QA1 Carbon Fiber Driveshaft Upgrade Rocks - Mullet Mustang - EP18

[@speedacademy]

Some of you have been asking about the benefits of a Carbon Fiber driveshaft over a aluminum or steel one. Weight is obviously a big factor but safety is an even more important one. If you’re racing or involved in an accident, the carbon fiber shreds like a broom, so it won’t bounce around and damage everything under the car or potentially come up through the floorboard like a steel or aluminum driveshaft may do.

[@bintangsena2249]

Speed Academy you make me thinking about starting a carbon fiber broom business 😂

[@noochmartin7711]

Google carbon arrow accident and click images. Yikes!

[@sublimegt500]

Speed Academy somebody told me that aluminum is better for the street because Rocks come up underneath and hit the carbon fiber and make it start pulling away. Is that true?

[@jonalarcon8564]

Speed Academy but if it chips its junk and has to be replaced it cant be repaired and at 1500 dollars forget it chromoly is the best and likes high speed unless you want to buy a titanium shaft which is stronger then carbon fiber , iv done my research on this subject and if you use two drive shaft safety loops you wont have driveshaft safety issues, if been running my safety loops since the early 80s in my chevelle

[@jonalarcon8564]

RS3 4 Me hey dont use aluminum for the street or carbon fiber use chromoly steel, it's best for all around use carbon fiber is expensive around 1500 dollars and if it chips or is damaged its junk and has to be replaced it cant be repaired , if you want to save on weight use carbon fiber on different car parts not drive train components and if your worried about safety with the shaft under the car install drive shaft safety loops they work I know been using them for years

[@duo02]

13:05 "Less load being put into the tranny" hey man to each their own lol

[@foolspeedahead]

Duo02 I named my Ford Transit “Caitlyn”. Lol

[@J2A61]

My God😱😂😂😂😂😂😂 i had to read it twice to understand lmao me and my brain was still under the car!!!!

[@Monstero5o]

Do a dyno run before and after using carbon drive shaft

[@CrossWindsPat]

Aweosme mod. Something I always wanted to do to my s2000 but it is a much smaller weight saving so might not be worth the money. Losing 19lbs of power train rotational mass is fantastic.

[@ethownzbh]

Yeah S2000 drive shafts are light as hell as they are. Can't imagine it being worth the money unless it's like a balls to the wall race car build.

[@thejohn6912]

Lucky rooster is correct (may not be 1 for every 20, I can’t confirm) but rotating mass is what affects performance the most, I’ve heard people getting these and improving throttle response greatly. Rotating mass is what really robs performance, thats why cars like the Lancer Evo has hollow camshafts, only saves a couple grams, but gives it 1k more rpms than stock mitsubishi eclipses that use the same motor with solid shafts

[@TABRO284]

The fit on that lip was top notch.

[@MitchDenham]

I really want a CF shaft for my 86. Its lightweight crank pulley alone made a considerable difference, can only imagine how well a CF shaft would do!

[@pvkjhilk8323]

they say 1 lb of rotational mass = around 4 lbs of static weight so would be around a 80lb power to weight gain supposedly

[@cruzanity7478]

Mullet looking, sounding, & driving very nice. Great job, guys 👍

[@mikegiles5038]

Great job guys.. I'm getting convinced that a 05, 06 mustang may be my next purchase.

[@cruzanity7478]

Mike Giles They are great cars. As an owner of an 05 GT, I recommend you look for an 07-09...Ford was still having minor issues with 05-06 models & if you could find an 07-09 with low miles on it...you will be a satisfied mustang owner.

[@mikegiles5038]

cruz_ thanks for the insight..im definitely following your build on KZbin and Instagram.. Just looking to make a good autocross and street car out of it.. Thanks!!!!

[@speedacademy]

Hey Mike, the 4.6L V8 S197 is a good purchase but as you can see it takes alot of work to make any real power from it. If we were to do it again, I think we'd shell out the extra cash and buy an 09+ with the Coyote V8 since that motor makes so much more power out of the box.

[@mikegiles5038]

Speed Academy very smart... Although your video gives a lot of ppl a vision and hope being that Chassis is difficult to make progress with..ill be looking into the 09 and 10 as well.. Thank you

[@nicksisson7538]

Mike Giles s2000

[@RobertKohut]

Where's Moose and Connie??

[@crazyviolent69]

Peter Tarach from. Modified mag. Boy do I miss that mag

[@mitsuhed]

crazyviolent69 same here, after scc ended, modified mag was my next choice.

[@mondomoleno.3404]

There were so many good import performance magazines back in the day. It's too bad Source Interlink axed them all except Super Street. Even finding a copy of that is getting hard to do these days.

[@DoRC]

I'm confused. How do they have a u joint on one end and a cv on the other. Unless the u joint is perfectly straight which it's not there's going to be vibration induced....

[@eddarell9474]

Yee-haw! Mullet Mustang is getting pimped out! Nice!

[@Stigs722]

Loving the mustang build

[@Hernandez471]

RX-8 already comes with a carbon drive shaft 😎

[@tsaltsirf2219]

Hernandez471 But no horsepower or torque

[@RallyDriva]

Hernandez471 Problem is that it comes with an RX-8 attached to it

[@MidShipCivic]

So does a 350z

[@Dub_Content]

Too bad you gotta put in oil every 5 miles

[@SARDOG]

It's actually an aluminum drive shaft that's hydrodipped ;)

[@RHBTurbochargers]

20lbs less in the car from the drivetrain itself... yeah you'd feel that

[@WarriorOfEden3033]

How advanced the Crown Vic is compared to the Mustang is amazing. Factory 1 piece aluminum drive shaft & factory watts links it was years a head of the Mustang

[@iVTECInside]

KZbin recommended a video filmed 10min away from me.. That's a first...

[@mondomoleno.3404]

This is my least favourite car in your fleet, but my favourite build. That is, I'm not a Mustang guy, but I like all the work you guys have done to it.

[@AutomotiveAnatomy]

You both are loosing weight but it is more noticeable on Dave. Keep it up brothers.

[@dro3023]

YES, IVE BEEN WAITING SO LONG

[@Christdeliverme]

Nice upgrade!

[@MistrMcGill]

Nice thick shaft

[@Leofred2000]

More Celica vids, plz!

[@stevengrizzle]

So when are you guys going to gut the car out?

[@PowellMoore]

Lip looks awesome she's looking real mean

[@adrianperez9894]

Omg, that v8 swapped brz right there!

[@kidmars93swagg]

That rusty front fender is killing me .My 05 s197 had that same issue .

[@andrewmcintosh9832]

Now you have more torque to plow into the crowds!

[@destruxandexploze2552]

The fact he’s not even struggling to hold it. It must eliminate so much rotating mass over the old one.

[@brentgoodkey3067]

gee nice like pipes there huge lot tourque neat good northern ontario

[@hatersaywhat8986]

Add the yokes (U joint) and carrier to the carbon, being you counted it on the ford driveshaft scale

[@frankth3frizz]

350z with a CF drive shaft checking in!

[@HermanWillems]

Probably nothing different. The 350z has already a carbon fiber standard from factory.

[@Twobarpsi]

Woot

[@foolspeedahead]

I want one for my 68 Camaro project. I’m putting a LS3/416 with a 4L80E and Heidts Pro-G IRS.

[@ravenstylea2]

Another great video!!

[@based_will]

that driveshaft is way too fancy for that old Mustang 😂

[@boostedbuiltgarage]

Guyssss! You gotta drop that exhaust, sand it back and spray it with some black VHT Flame proof paint! 😉🙄

[@pknlpr]

now good roll cage. safety first.

[@LocoBlitz81]

How do you eliminate NVH? I have it bad. Just installed the QA1 in my 2019 Mustang GT.

[@jerimiahbondy1565]

I don’t have a gt can I still use the same carbon fiber driveshaft

[@lcouvaras]

Would you guys consider using an my shifter

[@nbowling10trio]

Will it keep up with a stock altima yet?

[@pontiacmaniac7772]

Might not be able to keep up. But it is way cooler than an Altima.

[@DoRC]

You're insurance OK with the removal of your airbag?

[@tonylikesice]

hey fellas enough with the mustang and s2k, what's the update on the Celica. Getting ready to do a beams swap on my te72 and I need some tutorials!!

[@rogerramjet5092]

I remember seeing the magazine on news stands but never even picked it up. Wrongly assumed it was an oval track mag which holds zero interest for me. Now of coarse having watched this channel for yrs and having gone the web site. i really regret not just flipping thru it even once. I feel sure would have liked it. Based solely on the content I see presented here and the website. So checkout the web it has many of the same projects but with greater detail and background. Also some content not show on the channel. I learned of Pete's 930 months before it was even mentioned on the channel. There's also a build of an E-rod equipped 240sx. E-rod is GM SMOG LEGAL LS-3 6.2L 430HP all alloy badass crate motor.

[@Djtonydraper]

Nice video/install. Thanks for sharing. Wondering if this would be a good up-grade on my 2017-GT350..

[@excelerater]

looking to pick one up for my 2015...How was the improvement ?

[@mitchellspencer4726]

whats happening with the badass 2000? when will get to see the ep about engine teardown??

[@lilde66]

Have you done a dyno test before and after?

[@AndrewNL08]

yes!!

[@RobertKohut]

Nice!

[@WickedMachineWorks]

Must be time for a turbo!!!

[@jamesdewiel4736]

What to do for wheel hop?

[@ronniehardaway]

do you still have a horn with the quick release hub ?

[@pballer2005]

Too bad my driveshaft shop driveshaft was that well marked. I had to unbolt it, rotate it slightly, get it up to speed, rinse and repeat until the vibrations went away

[@supared25]

pballer2005 same here, and the bolts supplied were 5mm too long gouging into the pinion flange and one snapping before 50ft.lb. Had to drive the car from Ohio to NC obviously with a slight balance issue due to the bolt and the pinion bearing needed replacement by the time I got to NC. Cost me another $400 to have a shop replace it and $40 for a machine shop to get the bolt out, and another $20 for the right size bolts. DSS went dark on me.

[@joshpietro5790]

Where can I find the transmission linkage bushing for a 2010 mustang gt? It wasn't until I seen this video; that I was able to figure out what's up with my car.

[@speedacademy]

Sadly, there are no companies that make it. We have been contemplating making bushings but dont think there will be enough interest in it.

[@lilde66]

At 8:25 I believe I saw a nail in the front passenger tire can you check it.

[@matts490]

Hey did you dye your hair PT?

[@biggboysouth]

Man I still wish you guys would have gotten a 4th gen camaro or trans am instead but this stang is starting to get pretty decent.

[@pontiacmaniac7772]

biggboysouth I have a 95’ Firebird I’m about to do a bunch of stuff to

[@jameswright8563]

Where was the drive shaft? You installed a carporn fibre prop shaft, as far as I understand the drive shaft connects to the wheels, the prop shaft goes from the gearbox to the rear differential which is what you replaced.

[@flubdreload2818]

It’s still considered the driveshaft.

[@truthseeker8483]

The technical term for those bushes condition is shagged....for the full manly chin effect glue on fake grass onto chin spoiler and spray black...

[@party_boy69]

is the drive shaft a used/press release unit? I know it's canada but those bolts already have rust on them. Otherwise a very fancy bit of kit edit: assuming the bolts aren't coated because QA1 balances them by removing material

[@speedacademy]

Those bolts arent coated hence why they rusted so quick. There must have been moisture introduced into the packaging which caused it.

[@wakjob961]

No dyno before and after?

[@89DIDD]

Whoa! cmon guys! That's an overkill! Use a hollow stainless steel shaft instead, that's enough for the amount of power a modded NA 4.6L engine will deliver. I know you're seeking weight reduction, but just strip the interior, that's way cheaper! (I hope you eventually go for a SC to justify it). Nevertheless great video, interesting series, I'll keep up with the build.

[@matt2m]

89DIDD sponsored man I would not argue

[@89DIDD]

I wouldn't argue either, that's why expect a SC in the future, you could build a car with some serious torque with a CF shaft. They would only need a new transmission, diff, tires, brakes, etc.

[@SamnissArandeen]

I doubt boost is in the cards now that they have Stage 2 cams in it.

[@89DIDD]

Yeah I was thinking more like in a long distance future, when they've had the NA build finished and one they stop to look at it and think: "perhaps we should start a new proyect". Other than that I've always liked the idea of the NA build and still expect them to finish it as a NA build.

[@rogerramjet5092]

True, over kill YES, cool YES. Agree an SC WOULD BE COOL. On the coyote motors respond like crazy. 3-valves need all the help they can get. They have already exceeded the pwr gains I expected.

[@MrDannyd9]

if only you knew about the heat soak issues when making this. I imagine that the lower grille cover could have been removed.

[@speedacademy]

Oh it wouldve been such an easy job!

[@mrpmj00]

Is there a carbon fiber driveshaft for the 2014-2018 Corvette C7?

[@speedacademy]

If they havent made it yet, they are certainly working on it.

[@mikemahlen3713]

So I get it when people call third gens mullet machines but how the heck is a s197 a mullet car now? If anything, mullets "came back" during the s550 years lol

[@decorativeironplus4644]

hey guys great vid on doing the up grade , i have a question to you or anyone else reading this post . i have an 08 shelby mustang GT that has that two piece driveline . my car no matter how hard i try when i go to do a burn out the tires spin like crazy but cant get smoke off the tires even with the traction control off it has the 4.6 w/5 speed i have asked several other people so far no one can tell me why i have tried two other types of tires along with drag slicks played around with a different tune . my own conclusion theory is by it being a two piece driveline im thinking maybe its depriving it from torque making its way to the rear end any thoughts or suggestions ? . i have seen others the same year with a solid drive line blow the tires off the car but id like to find out for sure before i spend a bunch of money on it thanks Bill

[@chehystpewpur4754]

no

[@TheCdM1981]

Except for when it rips apart. Then it’s not much of an upgrade.

[@smumm]

What is that fresh looking CRZ/Prius looking car in the back @10:59?

[@BookerTJohnson]

Sean M 9th gen si

[@BunnyBUNGALO]

Idk why but I always thought that carbon fiber had bad torsional strength

[@MrPappysCobra]

2 piece out dated drive shaft. What is ford thinking!

[@ricardomcgrath4911]

damage danger trouble ago hard justice.

[@montyshelby]

Damn ur one short guy or ur about to take pictures Damn

[@ZoltarSoulFunk]

Where's Connie?

[@NhoyBarangay]

I have a DSS CF shaft for my S197 GT. But after seeing AM's drag race on their S550 with CF shaft it made me nervous launching my car hard.

[@snowyedgar]

Please paint the vent rings

[@jeffg213]

Why on earth is the dash in those cars so high?!

[@jimvines5589]

Jeff Grindstaff try sitting in a second gen trans am or Camaro. lol. I agree, it's high, but if you're too close to not see the tires on the car in front of you you're driving like a deuche anyway.

[@pontiacmaniac7772]

In my firebird, the dash is low but the hood is long.

[@ryanbarbolt3691]

Except driveshafts are almost always independently balanced.

[@chris77777777ify]

Dyno is the real test. Where is it

[@Z06Boss23]

mmmm plastic bushing are rusting on the sleeve?......okay lol

[@crazymodder2]

Dude you sit close as fuck to the steering wheel lmao!

[@DoRC]

The carbon driveshaft WILL NOT improve performance in any noticeable way other than the weight saved. Hell even QA1 doesn't mention performance gains on their website....

[@mustangsaully2377]

I have recorded a tenth difference in just a second gear pull with my aluminum driveshaft . Others have gotten a .1 or .2 tenths difference in the 1/4 mile with just a driveshaft difference.

[@boostedbuiltgarage]

Do R/C! It will certainly increase throttle response and be free-er revving. Half the weight, way less rotational inertia!

[@tsaltsirf2219]

Do R/C! Stick to RC cars

[@DoRC]

Tsal Tsirf haha. ok I'll quit my 15 year career as a mechanic tomorrow. I suppose I should have said that a lighter driveshaft will not make a car noticably faster to the average driver. If you can tell 1/10 of a second in 14 seconds by the seat of your pants good for you. That's about a 1 percent change. There are a lot of things drag racers do to eek milliseconds out of their runs but I'm guessing there are a lot of things that $1200 would be better spent on by the vast majority of people.

[@dinobot_maximize]

why isnt the CV carbon lol and the bolts too while theyre at it. eh i know thares probably limitations on the kind of shapes you can make with carbon.

[@dinobot_maximize]

also, why get rid of the steering wheel with the airbag? you may have a better seat belt system but isnt your skull going to fly off without a pillow to land on? always seems reckless to get rid of any airbags. you may have high confidence in your driving but if you take that thing outside in public who has very questionable driving skill, some circumstances can be out of your control and you just have no choice but to crash horribly.

[@dinobot_maximize]

why does the nanny state deem it illegal to drive without a seatbelt but get rid of an airbag, no problem lol not that i care anything about nanny states but i wouldnt remove any safety items. i wear a seat belt for safety not because the state says.

[@dinobot_maximize]

or why doesnt the state bitch about really loud exhausts? yet there are laws about unreasonable noise. a loud exhaust isnt reasonable except to car enthusiasts idea of cool and fun. but its actually pretty annoying. imagine everyone was a car enthusiast. then it would just be a droning hell 24/7.

[@mustangsaully2377]

It is illegal in Canada to remove a functioning air bag from a vehicle. They just roll the dice on not getting ticketed for it. Considering the car probably isn't a daily driver the chances they get unlucky and get pulled over by a cop who cares about that stuff is low.

[@rogerramjet5092]

Because it's too situational dependent and subjective. Think of all the times you pop it into neutral just to do a rev at good spot. I used to be really annoyed at LOUD Harleys. Till one day asked a guy about it, he just showed me a patch on his vest "loud pipes save lives". The light dawned...!

[@The570Experience]

I've seen these break countless times...no thx

[@MiesvanderLippe]

No wonder it's rusted to shit right above the exhaust...

[@dinxsy8069]

Does Dave actually get any oil and grime under his fingernails? Take the RA24 didn't see one nut spun was Moose at it, his soul is in that car that's for sure.

[@zinoabreu3029]

Where's the badass2000 !!!!

[@zig-zagwraps9992]

ZIno Abreu the motor blew and they're deciding too buy a new one or rebuild the blown one so I'm guessing the are waiting on machine shop or delivery of new motor

[@audiwankenobi361]

how can you NOT know who sent you a gift?....that's soo shallow!.....your appreciation wouldn't even cover that dudes pinky toe but yet he made himself known....smh

[@ConLLee]

im gonna go with the guy didnt include his name with the package... but i dont really understand your comment and its over a year old so yeah

[@ExtraRust]

please do one build at a time like the k swapped civic, all these cars are too much to keep up with

[@davapikyan403]

No not necessarily. I don't watch any of the jdm shit so if they did one build at a time I wouldn't watch them for months but like this I watch the stuff I want to watch

[@ethownzbh]

I, for one, can keep up just fine. Plus the K swapped civic is already done with the main build. They'll just do little upgrade parts here and there with this car and like they've always done. If you can't keep up just go back and rewatch some stuff.

[@itzzToon]

lol. the only cars i can recall from memory that aren't "JDM" are this and the Porsche. Everything else is practically Japanese. I do like the mixing up of flavors though

[@frank09busa]

$1400.00 bucks can be spent elsewhere and be actually productive

[@chasevineland1508]

Carbon shaft is the last upgrade I would do... been there. I would rather invest in better rims way before.

[@zig-zagwraps9992]

Chase Vineland wheels you mean rims are for basketball courts

[@j.m.5995]

Who in their right mind would waste money on a Ford mustang

[@FranciscoLopez-xp5jv]

It is easier and cheaper to get 1000whp or 2g lateral accel modding a Mustang than any other more expensive car
