The creativity juices really must have been flowing the day Turn Fourteen designed those T shirts.

[@rogerramjet5092]

True doesn't look like a lot effort was spent on the design. But look at the chevy bowtie or fords blue oval. Pretty plain also. Honda And Acura??? just sayin .

[@VS666]

sometimes less is more. minimalism. that doesn't apply to horsepower however...

[@kennywilcox7155]

Think it's supposed to look like those "Supreme" logos that everyone and their mother has these days...big in the tuner world not sure if it's caught on in the muscle car scene too but maybe they're trying to break it in there too? Who knows lol obviously different color than the Supreme red but you get my point.

[@based_will]

I like this series because it shows that you can buy a high milage car as long as it's mechanically sound. and its still worth it to do some sick mods to it. you don't always have to start with a perfect low milage car.

[@speedacademy]

Exactly, glad you're on the same page as we are!

[@WarriorOfEden3033]

Never understood the fear of miles. It's a car you drive it miles are a given

[@brucebrucestofiston5554]

I love how Sasha doesn't say anything unless completely necessary.

[@speedacademydave]

He is a man of few words but many thoughts.

[@kennywilcox7155]

I almost feel like he's annoyed to be bothered by a camera to the face lol

[@grocer3]

Why don't you guys have more subs? I think it may be because a majority of the other "automotive youtubers" are all swag and no go. I love your videos, I feel like I'm actually learning something new and not just getting clickbaited and having my time wasted.

[@speedacademy]

Thats so great to hear because thats our goal. It means less video and more prep but we hope in the long run it pays off.

[@gorillazgarage7482]

You need a bit more showmanship

[@madmiata1887]

@@speedacademy it paid off, look at ya now!!!!

[@doctorlobsteroctopus]

Is this thing headed to Florida? CAUSE IT"S ON THE WAY TO GAINSVILLE!!! I'll see myself out

[@jronayne88]

able to appreciate this as my family lives there. there are a million gainesvilles though xD lol

[@doctorlobsteroctopus]

jronayne88 haha hadn't even considered that but you're right!

[@rogerramjet5092]

Thanks much respect for that. It's always upsetting to see a punner thrown out.

[@speedacademy]

Looks like DP's been making some gains on the beard grey hairs too!

[@Raven05R6]

Looks like Peter's been skipping Hair Day and making those losses.

[@Captaindan7141]

I love the content. You guys are living the dream!

[@krusher74]

Poor Sasha when noobs turn up with their broken car!

[@speedacademydave]

settle down, it unbroke itself! :P

[@rogerramjet5092]

I think the plug porcelain looseness was a good catch . not sure I would have noticed, Swapping out to the old champion plugs seem to fix the misfire. So cool. All is good again.

[@CRUSHFACTORPC]

Their not there

[@AndrewNL08]

I feel like everyone is concerned with more power but ignore the balance aspect of actual racing. The car is heavy, the engine runs good for it's age and to be honest most great racing cars dont have 400 plus horspower to make them the best on track. If I could I would gut my car and replace parts that I removed with fiberglass panels that can be removed more easily for actual tracking and lighten up all my major body panels. Replace my suspension with all lighter than stock parts and replace my seats with carbon fiber or fiberglass...and dial in my road racing skills...ooh and biger brakes! I love watching this chanel because this is fun seeing what could be if I could, seeing what can be with the car I can say I actually own, freakn sweet! Heck, didn't someone mention that with the previous mods, the Mustang felt almost like a 911 on track?! Can't wait to see what's next, you guys give me hope!

[@Mtnbike121]

You're 100% right, weight is the first thing i consider when looking at a track car, people always overlook weight when it comes to a track car.

[@lawrences1347]

This 10:06 video would have been 5 hours of content for B is for Build.

[@cgault11]

Lawrence Sullivan Love B is for Build but you are probably right. Lol.

[@michaelbarnett2077]

Lawrence Sullivan The reason I can no longer watch B is for build.

[@Junhung90]

yea love b is for build but his progress is really too slow...

[@marcosaruca5283]

you guys should do a port and polish that would be great content plus a good horsepower adder

[@speedacademydave]

We'd love to get some CNC'd heads for this engine, it would really make some sweet jam, but these are pretty pricy pieces so not sure we'll man up and do it. A DIY port job is tempting if we ever find ourselves pulling the heads off.

[@Sim2Real.]

But that´s is hard af to do!

[@marcosaruca5283]

i mean its theoretically free if you do it yourself but if you have a machine shop do it im sure itll still be cheaper than buying heads....also itll be kool to see a master machinist at work explaining what he does kinda when you built your rotary

[@kennywilcox7155]

@David Pratte The way this build is going, I'd bet you will before the end of the year is up lmao just not having great luck thus far!

[@pheonixfps9248]

If your loosing that much bottom end on cams alone now, with ported heads, itll be far worse down low. It'll be doughie as shit. The reason is, is that there is more area to fill in the head, with the same amount of vaccum, which actually causes the air speed to slow. Once in the range, itll be great, but if it's still a streeter, just leave it as is and port match the heads.

[@BadDFWDrivers]

Extra RPM looks awesome with that chart.

[@speedacademy]

We chickened out too, thought about 7K but dont want to wreck anything.

[@braydenwilcox5521]

I love the videos, I plan to get a 3-valve soon and with cams (especially stage 2 specs and up) and springs, they are safe to go 7000 rpm. the hot rod cams for example are good up to 6800 rpm, but you need springs to rev farther than that. Great works guys, thanks for your videos! 👍

[@ldadol]

Keep up the good work gentlemen, the content is getting better and better!

[@speedacademy]

Thanks for watching, glad you enjoy the content.

[@chrissoto1657]

I still like how you include the problems that you incur

[@speedacademy]

We're trying to keep it real!

[@Mike-xt2ot]

The numbers are great for what you are working with. Up to this point a large amount of money invested into achieving the power numbers seen out of a 400 dollar scrap yard LR4 4.8 with a sloppy cam swap. I think i would've LS swapped it and used the 15 grand in savings to pay for a second vehicle. But yall are doing an excellent job.

[@therealboofighter]

Nice work on the car boys, so cool that you get to see the results on a dyno.

[@speedacademy]

Thanks for watching, glad you enjoy the content.

[@OhHolliwould]

As always awesome content. DP! You hitting the gym, bud? Looking good!

[@derrek1971]

MSD coils and NGK plugs. Champion plugs are for lawnmowers.

[@gerrit2107]

Conclusion: dont buy them spark plugs again :|

[@speedacademydave]

true story

[@DBGMLV]

A Coyote swap would be real nice, but also expensive as f**k. This is pretty much what I would do, except I'd maybe do is do the heads. A bit of porting, bigger valves. But that's pretty much it. And if I wanted even more power maybe throw a ProCharger on it.

[@speedacademy]

Exactly, the money is better spent on other mods or projects.

[@DrNoseWater]

Love the content guys, keep up the stellar work!

[@Shady97342]

Love all the build series' especially the (BAD)ASS2000. Also you liked some of my Instagram pictures and I may have fanboyed just a little.

[@asorjvideochannel3895]

My 06 mustang gt auto premium got 363 rwhp/348 rwtq comp cams stg2 XFI SPR and rpm set into 6900 with only LT headers, X-pipe, corsa touring cat-back, JLT series 2 104" Sct X3 strategy file tuned by me (91 Oct).. Back on time 2009 Adding cj intake manifold, BBK TB 62mm, frp spark plugs zero degree, accel super coils, steeda udp, steeda spacer, 3.73 gear ratio, intrax lowering springs over oem anti shock and it goes up to 402 rwhp/389 rwtq (442 hp @ engine) re-tuned again by me with 91 Oct tune file and using 95 Oct on pump gas and it was absolutely amazing performance it's making spinning between shifting until 4th gear and it's automatic tires are Brielle p zero 235/55/17 front / 245/55/17 rear even in dig it will also spin a lot.. Since 2016 til now I am working slowly and carefully on custom twin turbo setup with fully built strokerd cammed engine, fully built gearbox, one piece drive shaft carbon, fuel sys, new full exhaust sys configuration with corsa touring cat-back and Recaro seats.. And see how much power i can get with daily use..

[@tomkord220]

When the 3V does finally go to the big dyno in the sky, you should import a Barra: dunno if anyone's done it yet, but a 1000hp turbo six in an S197 would certainly get some attention lol

[@speedacademy]

man we would love to! That motor is insane for power.

[@tomkord220]

just let me know, I'll put one in a box for you lol

[@rogerramjet5092]

Coils on mod motors are maintenance items. You should just change them All around 85 to 100k miles. Because they are on borrowed time by then. They are just sm. cooked unlike the coil used with distributor which is large and out in the air and last till it dies which is usually beyond 150 k mile.

[@speedacademydave]

Good to know, thanks Roger!

[@skinanbonesOG]

DP you might want to switch back to a black cap, that white one seems to be bleeding down into the beard

[@harrylinka5227]

I've got 352 Plus horsepower 340 1 Tork with competition cam stage one and Steeda motion plates and phaser lockout full lockout if you do this you will get an additional 20 horsepower plus twerk desalvo racing I did the dino and what a beautiful job they did my Mustang is a 2006 GT

[@nathanunderwood6920]

Been waiting for this..

[@RRninja-jq6lp]

swap 5.0 = fix all problems

[@speedacademy]

We want to sooo badly, but it's not a cheap swap.

[@rkan665]

Speed Academy 2.3 ecoBOOOOOOOOOOST!

[@wiliambanquiter8039]

swap the old honda motor from pt's bros car😂

[@stevendoporto2123]

I paid 6,000 for my swap with bolt ons and tune and made 436hp 407tq

[@kikosmith2088]

Robert must be rich. Like that

[@gedasalekveravicius5466]

I still think megasquirt will be better and (maybe) easier to tune in my opinion you don't nneed turbo for that, also lauch control and other.

[@andrestnt]

325rwh is not bad, i would be lucky to get that with my 331 stroker. one thing is for sure, you need port and polish work on the heads to take a real advantage of those cams.

[@MrNRvS]

Put some vernier cam gears on, and do an episode degreeing in the cams. Try to get back some of the area under the curve that you lost.

[@speedacademy]

That's so much work though, sadly we don't have the time for it at the moment.

[@Stigs722]

This build is so much better than the B is for build turbo mustang

[@garibay711cod]

My 08 GT-5 Speed Long Tube Headers CAI JTL 37'3 gears 62 mm throttle body Pulleys HOT ROD CAMS 93 OCT Tune....Make 344 RWHP !!! Thats 400HP at the crank :)

[@lilldebby2592]

Not surprised. I work at oreilly’s and the only spark plugs that get warranted out is auto lite 😂

[@eirikauster]

Would be cool to see some outside shots of the car during track testing. With a followcar or something.

[@rufles74]

Nice!! throttle body upgrade, u/d pulleys, intake or control valve deletes,...... can't wait to see the finish product. I have 2005 gt black with 253000 miles on it, pulls hard, 3.73, airaid cai, u/d pulleys, email tune.... exhaust is next.

[@speedacademy]

Deletes are next, but other than that power mods done.

[@79chevy901]

Sounds good fellas.

[@harrylinka5227]

With a proper tune you can get 350 horsepower rear wheel 330 foot pounds of torque with the stage one competition cam but you have to have the tune without the tune I was making 320 rear-wheel horsepower

[@mtktm]

NEVER use autolites or E3 plugs. garbage

[@XxIBRAHIMxX11]

Lol i guess thats why my car runs like shit and shake at idle < E3

[@DonSodaRomero]

mtktm E3 has been good to me 😂

[@jacobwebb8818]

I've heard E3's are good but expensive all the tests I've seen E3's make like 1-2 extra horsepower 😂 lower impedance maybe?

[@guynoir3116]

Seems there's lots of bad plugs for these 3 valves , make sure you use one piece plugs .

[@whatsreallygoingon253]

it was those plugs for sure i had one that had a tiny hairline crack that made me spend 2 grand chasing a misfire

[@Gravstein]

Not bad for an old boat anchor! Boost next maybe?

[@ryanvignogna4643]

That car needs NGK Iridiums those are the best spark plugs

[@bandwagon240]

Ryan Vignogna Just regular V-Powers are really the way to go. I put them in everything I have with an engine, even my lawnmower.

[@speedacademydave]

unfortunately NGK doesn't make a plug that fits these oddball '05 to '09 4.6L Ford V8's. There's very few companies that make plugs for it, the Champion platinums are literally the highest quality plug we could find for it. In '10 Ford switched to a more common spark plug, so one more reason for a Coyote swap.

[@ryanvignogna4643]

David Pratte that's crazy I didn't know that. I used to have a pretty built wrx and NGK even makes plugs for that... I swear by those spark plugs man I could physically feel the difference when I switched to them.

[@speedacademydave]

ya NGK plugs are all we run in our Japanese cars. Can't beat em.

[@bandwagon240]

That is nuts, I guess nobody really wants the liability headache of dealing with the 3v. Pity as if anyone can do it correctly, NGK can. Oh well, motor is garbage. Throw it out, install a Coyote instead. Oh the sacrifices...

[@robostrikeyou4365]

No 2Jz It needs a Ford 4.0 Turbo Basrra engine from Aus. They can make 600 hp on stock bottom end.

[@cajunspecial238]

RoboStrikeYou.....or a domestic 5.0 Coyote. makes more than 600 with a few bolt ons and a tune.

[@speedacademy]

We love those engines, would be great to get one here eventually.

[@robostrikeyou4365]

project mullet could be changed to Project Bogan with a Barra fitted.

[@louie111887]

Freaken subscribed! I got a 05 GT myself. You should nitrous it. Nothing serious just a 100 shot.

[@kennywilcox7155]

If I've learned anything from this build so far it's that I never want to own a 4.7L Mustang in my life lol just seems like a big pain in the balls to do anything that should be mostly routine. I'm sure the 5.0 Coyote motors are just as annoying but I have no experience with it nor have I seen anyone do videos like this so I'm assuming it's gotten better hahaha looking forward to more vids of this high mileage beast doing good shit on the track.

[@speedacademy]

It is a sluggish motor but working on it isnt crazy awful. Its a typical V8. You get into the newer engines and they're really awful!

[@Trill44471]

And badass mustang man

[@PGHdrift]

Soooo we gonna see some burn outs jeeeeezzz

[@speedacademy]

Soon! One more wrenching episode, then we hit the track HARD

[@fordmech7913]

Should have done the nsr vs the vsr honestly I prefer the nsr stage 2 127200

[@danielcgomez]

bump up the compression ratio, then the losses lower down the rpm range would come back and increase the upper rpms figures even more!

[@broadwayline]

Why didn't you show Sashys aggressive angry testing?! Also Dave I keep telling you I got a coyote that made 436 wheel hooked to a 6r80 + f150 driveline laying on my floor collecting dust....

[@speedacademy]

Angry tuning means rev limiter action lol

[@joshuamittie791]

Do you still where u at

[@rudis1994]

Why those spark plugs ceramic piece get loose, i had that experience with really good spark plugs.

[@4ener_]

I have Flowmasters exhaust on my 06 GT with comp cams sounds beautiful gas mileage kinda ugly tho lol

[@gedasalekveravicius5466]

Awesome videos like always. And mustang is my favourite. Would you port'n'polish it's head? Some extra Airflow and powaahh

[@speedacademy]

If it didn't require tearing the whole motor down then we would certainly consider it.

[@yothegaragebrodrick4113]

Thats weird, I have autolite plugs in my car and it works great. From my experience I heard they made great plugs.. Clearly not great quality control though haha

[@SumnerKidd]

Can you guys please do a e3 spark plug test next time you are at the dyno? Would love to see how they perform with dyno evidence, seems like they are snake oil so it would be cool to see the results.

[@speedacademy]

Sure we'll try to do that but we've tested them before and they don't really make any reasonable power.

[@TheTortugitaTURBO]

Sasha be like. let me do MY thing! and shut up lol.

[@OnDUBzProductions]

love gains

[@Ran-dom1]

The cam adds to everything, isn't that stock air intake, stock exhaust, stock everything else? so just adding a cam into a stock engine isn't going to have huge gains, but I think if you were to add more to it, like exhaust, maybe injectors etc you would see HUGE gains.

[@justjcs]

They payed someone from FIVERR to design those turn fourteen t-shirts.

[@Ultegra10SPD]

Lucky that high mileage car didn’t have two piece plugs in it or they had already been changed. if they didn’t come out your day is over. That and this 3v high mileage engine + cam swap - did you change the cam phasers? U10

[@anthonygonzalez8818]

Autolite spark plugs are trashhh!!!

[@CSkwirl]

I'm in Australia, I've never seen those plugs here but I can't remember how many forums or videos I've seen that say how crap they are! Don't know how they didn't know that.

[@speedacademydave]

we know the Autolites are junk (they're actually the same plug as the Ford Motorcraft plugs), but it's all we could get when we flooded the Champions. We swapped the old Champions in out of desperation but we'll put some fresh ones in asap.

[@rogerramjet5092]

Used to be the OEM supplier for ford. Just a bad few plugs out of how many thousands?? It's one of those opinion luck things.

[@yunclehead]

Roger, you have the wrong sampling size. Its not a few bad plugs out of how many thousands because the guys didn't test thousands of plugs, its 3 bad plugs out of 8. That's a failure rate of 37.5% which is fully ridiculous. One bad plug out of 8 is considered totally unacceptable because of the engine's degree of performance degradation.

[@cruzanity7478]

What about an Off Road H pipe or Off Road X pipe? That would add a couple horsepower and make a mustang sound very aggresive. The SCT tunner will take away the check engine light that the off road mid pipe throws out (due to the catylitic converters deleted)

[@speedacademy]

We've got an X pipe on it already! Watch the previous videos.

[@seanhenry8030]

Give it the old "DIY the hell not?" Basic, home port job if the heads are off again.

[@smoke_oguwop]

Imrc plates would of helped it rev more that’s why the rpms fell so much

[@CottonRamen]

install Ford Racing black lung manifold. these rev up to 7k safely.

[@ecoboostluke1755]

Question. If a car loses power under 3,500 rpm and gains power afterwards. Why can’t you just set the tuning back to what it was last run as far as under 3,500 rpm and then keep the current tuning for after 3,500? In theory it makes sense. Someone intelligent please explain why it does not work like that.

[@cabrera373]

How much is the cost to tune a 97 mustang gt ? I want to know prices plsease

[@vegasfordguy]

Never use any plugs except for Motorcraft! Especially in the 3 valve. Same thing goes for aftermarket coil packs, only use genuine OEM! This is common knowledge. I can't believe you guys don't know this.

[@kevingilroy]

Oh boy. 30 horsepower for only about 2 thousand dollars!

[@j-tuned1955]

Might have slammed fuel in to the spark plugs when it flooded. Lucky it didn't bend valves if that's the case.

[@speedacademydave]

Ya we did a leakdown test and it was all good.

[@MendicantBias1]

Correction: Make some 'jam' with the new stage 2 Comp Cams.

[@302hobronco]

What cam is the stg2?

[@vaioskaliakoudas6388]

Why don't you turbochage your car? It'll make more horsepower and it'll be more fun to drive. And make sure to upgrade the tranny and the clutch to response to the power gains w/ no issues

[@HandSolo1]

What exhaust does it have?

[@aussiebloke609]

Of _course_ you can just drop those cams in and take it for a drive. No one promised the engine would be running well...just running. (For a given value of "running.") :-P

[@Trill44471]

How much was the cam install ?

[@ruru2500]

How much ya makin' in that cammed v8? 325.... what??

[@jkflorida]

Get some NGK's!! Those champions love to drop the ceramic and score your cylinder wall! I've seen it happen.

[@sergebouchard2672]

It look like you have a GT 350 intake Manifold, would these CAM fit on a 2017 GT or do you know if Comp Cams have somes to fit a 2017

No thats the stock intake manifold. You can certainly get cams for your 2017 Mustang, just check their site!

Mullets were an 80’s thing. That’s 2005-09 Mustang = no mullets here.

[@pabauza]

Dave and Petter, I'm considering a Mustang for the track. Do you have any engine concerns with such a high milage car?

[@speedacademy]

Nope just make sure you've done all the maintenance and mods. Its a great way to get a car on the cheap.

[@pabauza]

Speed Academy Cool thanks. I have a new GT but will probably get an 05-06 for the track. Looking forward for more vids

[@ryanbarbolt3691]

Thanks

[@408modelshop]

"gained power with cams!" captain obvious over here..

[@chickenfishhybrid44]

Autolite spark plugs are garbage! Ive never seen the porcelain be loose but doesnt surprise me at all. Ive had multuple issues with them causing cars to run like shit or have misfires. I strongly reccomend motorcraft plugs, especially when dealing with that goofy style.

[@speedacademy]

Well we've definitely learned our lesson.

[@g-mane7497]

why does it look like dave lost some weight?

[@300zxdriver]

Heard engine is hard to work on.

Why are even power ratings measured/showed only at peaks? Thats actually really misleading. Imho, the area, under the curve, would describe the power a lot better. I mean, lets say - 2 engines - both rev to 5k. 300 torque from 2000 - 4000 RPMs is going to be a lot more, than 400 torque at 4500, but "turbo lag" torque levels up untill then.

[@speedacademy]

That's the biggest issue when comparing dyno results no one ever covers area under the curve just peak!
