2011 Mustang V6 3.7L Dyno Before and After BBK Long Tube Headers and BBK Off Road X-Pipe

Here are the Dyno results before and after the BBK Long Tube Headers and BBK Off Road X-Pipe were installed. The car made 315RWHP and 270RWTQ and it was 87 degrees and the humidity was at 38%. Before LTs and X-Pipe I made 292RWHP and 276RWTQ with only a C&L Cold Air Intake, Roush Axle Back Exhaust, and an American Muscle Bama Race 93 Tune. Both before and after dyno pulls were done at the same place.

Here is the thing you guys don't understand ...... oh get the vs it's better ..... This car is 20 000 dollars ..... for 305 to crank so about 265 to wheel he made a very nice 50 Hp gain for a thousand ..... very good numbers you can call it slow your get starts at 30 000 you know what I can put in my "shity" v6 for 10000 $ it will smoke any v8 in reverse .... my car club president is a 2011 v6 runs a 10.6 second quarter mile .... v6 plus procharger ... And few other mods guess what still under 30000$ .... it doesn't matter if it's a v6 or a v8 or a 4 cylinder turbo .... we're mustangs all of us ...stop hating you don't like it don't watch don't comment as far as I'm concerned it's a Mustang that's all I c is a sexy Mustang doing good work !!!

[@fitguyonline1502]

where did you see 50 hp? lol... kind of confused bro... it went from 292 to 315, that's 23hp difference.... My stock 2001 ls1 ws6 was pushing out 296 to the wheels, then I just simply got a hypertech chip and a k&N filter for 350 combined and endued up getting 327... so idk why you are giving this guy credit for dropping 1,000 into a v6 and getting hardly any gains. Before you comment, the car has 105,000 on it, i spent 11,000 when i bought it with 92,000 3 years ago. I also had no clue about modding a car nor engine work at the time... I wish I had a nice place where I could put some headers and exhaust on... I hate paying someone hundreds of dollars to do work on an engine that, if I had the equipment I could do myself lol... This car does sound awesome though!! I'll give him credit on that

[@3SevenStangVids]

Mike Chrisman 50hp at the crank hes not talking about at the wheels

[@fitguyonline1502]

got ya, but all that matters is what you get to the wheels... didn't catch it the first time watching. thanks

[@3SevenStangVids]

yeah thats true you can make 500hp at the crank but if your drive train loss is 20% or more you've got bragging rights thats about it lol

[@fitguyonline1502]

lol man, hey question though... how is he saying that he gained 50 at the crank and only 23 to the wheels... That would mean that since his car is pushing 300ish to the wheels it would have 600 at the crank lol... Simple math ratio right? 23:50 is clost to 1:2... so 305:610 if it's the same ratio

[@JamesDuncan1]

With this setup you can make a lot of money on the street. A lot of import car owners don't want to race the 5.0 but everyone wants to go up against a v6. This is a sleeper with one or two more mods

[@heyitschinoable]

A lot of imports dont want to race the v8?! Are you kidding me get your head out of your ass! Take that to the quarter mile when your done building it and race it against a built import. Or BETTER yet take it to an auto x event OH WAIT I FORGOT IT CANT HANDLE CORNERS. ( facepalm.)

[@cerebrix]

heyitschinoable so you dont know autocross at all. Google Sam Strano. 7x SCCA National Champion + 7x SCCA ProSolo Class Champion, 2009 SCCA ProSolo Overall Champion. he won a lot of those titles in a Mustang with stock power and just tuned suspension. I dare you to call his shop (strano performance parts), ask for Sam, and tell him you think Mustang's can corner. Sam would laugh at you harder than you've ever been laughed at or ridiculed before in your life.

[@JamesDuncan1]

heyitschinoable haha what are you talking about fool. Please show me a faster car stock for stock than a $30,000 5.0 GT. Please. If you are talking mods anyone can mod their car to be fast numb nuts. Even Hondas so yes I stand by my statement. And if you think Mustangs can't handle corners google a car called the laguna seca boss 302... Specifically the 2012-2014 models. It rapes other cars like the M3 on the nurburgring. (face palm)

[@pwnedbygary]

The 5.0 puts down 50hp more than this stock, and doesnt weight much more. i wouldnt really consider these v6's sleepers either, as they arent grandma's grocery getter with a LSX or something inside it, but the body of a sports cars with a decent engine.

@Dan Marshall people own V6 Mustangs for a reason. Not taking anything away from the awesome coyote which I love, but there is a cool novelty in owning a 3.7. This is the first 6 cylinder Mustang with some REAL power. And honestly, we like being able to run with 335i's, Challenger RT's, and any GT minus mods pre 2011. The insurance is much lower too. The only thing that sucks is losing that classic Mustang roar, lol. I love the V8, but Ford has truly made an awesome V6! If you don't mind sounding like a Toyota Supra, that is lol.

Thank you for the dyno test. I watched the BBK install. I appreciate the 3.7 love. I look foward to the next mod. I do not understand how one can claim that they love Mustangs but trash them if they are not V8s. Are they just scared shitless that a V6 will beat them?

[@skybluemarshall]

It's a just matter of preference, that's all. Some people want the best of both worlds: A very nice looking car, with great styling, good mileage on trips and commutes, without worrying about gas money or $200 more per month in ownership costs, MUCH more power and acceleration than most bland, vanilla, 4 banger Asian commuters. The 2011+ pony delivers all of this in spades. Not one person in 8 years, ever called my 2004 Honda Civic "A beautiful car". No excuses. I bought a Mustang and I love it.

[@Blonde_Cyborg]

Smart decision to buy a v6. Proud owner of a 2013 v6 manual with performance pack as only option. Couple of carbon fiber pieces, cai, tune, one piece aluminum drive shaft, cams, headers, then either super charger or pro charge and let's see the v8 people talk then as I run right past them. Ohhhh yeah while retaining good gas mileage, lower cost to own, lower insurance, and will still be less than a basic v8.... This day in age no real reason to get a v8 any more. Nice vid also! Cheers

[@ckboy221]

hey, if u start getting annoyed with the raspiness of the roush but still wanna keep the volume, try out the slp loudmouth exhaust. i had an offroad roush setup as well and only bought the slps because it was basically a straight pipe. LOVED the sound. i wish i had a video of it now but i cant record it properly anywhere around here. i do have a video of my roush o/r setup though. check it out sometime.

[@srvanddt1]

Heck, I do not think my H/C/I 90 Mustang even puts this much down. Proves what technology can do. Very nice numbers!!

[@skybluemarshall]

The supposed arguments for buying a GT: 1.They magically cost the same as an equally equipped V6, even though Ford MSRP is $8,550 more. I guess car dealers are just really nice guys. 2.They magically get 30mpg at 80mph, even though EPA rating is 15/26mpg. 3.GT insurance costs the same as a V6, even though the rest of us are quoted $70-$120 more per month. Dudes! The GT is a GREAT car, for a lot more money. Got cash? Buy a GT. The V6 is a GOOD car. Low on cash? Buy a V6. Now, please stop the BS.

Sounds wicked man, 315 rwhp is damn nice too! Noticed it lost a few torques with the headers and off-road x-pipe. Makes my wonder if a catted x-pipe or less free flowing axle backs could help with that without hurting too much of the top end power.

[@joeysanabria1]

Thanks for videos brody... I am about to add the same headers and mid pipes. The mods i have right now is Air Raid intake, Borla ATAK axle back and Bama tune on my 2014 V6 Mustang. My question is... Do the drive that daily and if so does the cops stop you? Thats what I'm a little scared about.... Your stang sounds amazingly awesome

[@ShillBilll]

Just picked up a 2014 mustang V6. Base model options.First mod was simply a K&N Filter, and ordered a 93 octane bama race tune. This car gets GREAT mpg when you don't have your foot in it even with the tune. As far as power it will smash on mustangs up to 2010 (it will lose if you don't have a tune as i've compared before and after). The 5.0"s are BEAST machines and i used to be a chevy guy. I raced a 5.0 mustang and took him off of the line ONLY because 5.0 wont get traction without slicks.

[@mikesanto70]

@pastelasoproductions Have you ran the 1/4 mi yet with the new #'s the 315rwhp / 270Tq ? Also you should put some 4:10 or 3:73's in that thing and it will really pick it up with your new found power!!! Nice #'s and the BBK longtubes are a way better deal than Borlas LT's,

Nice Car for sure and very close to my 2013 V6Premium/Performance Package (Black/Brown Leather) Airaid CAI, Bama Tune (93Octane) 73MM Steeda Throttle Body, Steeda LT Headers, Steeda Exhaust. My numbers were almost identical with yours just the CAI and Tune. The throttle body is the only thing I have that you don't and it really made a difference. 337 HP/291 Torque on Steeda's Dyno. Only other mod I'll be doing isSteeda lowering springs. Enjoy your car man, I know I'm lovin mine!

[@ronnieoshay5796]

I've run a similar setup on my 2014 V6 mustang. BBK long tube headers, BBK off road pipe, Roush Axleback, BBK CAI, BBK 73mm throttle body, 4.10 ford racing gears, and tuned for these mods specifically by MPT. I've never dyno tested it but it runs 4.5 0-60 and it clears 185mph. I never thought a v6 would run the way these do if you mod them right

[@simbanugz2906]

Lol clears 185? Man I have a fully built motor running a coyote throttle body, fbo with 75-100 shot of spray. I've hit 152 N/a 160 on spray.

[@V6MustangPerformance]

These new V6's are very impressive. 23 RWHP is sweet. My Bassani full exhaust set put out about 29 RWHP. The stock headers are quite restrictive. These LT headers are a great Mod.

What are the tires and rims?! They're too nice!

[@TooManyChoices1]

Yeah the 6ftlbs of torque that were lost scare me lol. I want headers, but I want to gain torque , not lose it lol. Do you track(1/4, or circuit) race this car? If 1/4 , what ate your times like before and after long tubes?

I have a 2012 mustang v6 manual 6 speed right now, but I also used to have a 06 mustang v6 manual 5 speed. I did like that 06 but it was a slow car. I am not trying to insult you but I am just curious what v8 you beat with that motor... the only mods I had to my 06 were a airaid cai and a tune.

[@twinturrbo406]

@JerryMiahGonzo ... i believe those are GT500 wheels, they are like $144.00 per rim, not too bad for an 18x10 ... here is a link where you can buy some from, they have a blown V6 3.7 Mustang, it went 11.80's@116mph so far, and well over 30mpg !!! My 2012 will have this blower soon ......

[@mattspontiacta]

Mine is a 93 LT1 Firehawk rated at 300 flywheel hp. Most Hawks on youtube dyno stock at 270-280 rwhp. depending on auto or manual transmissions. With my headers, 3" ORP , tune, she dynoed 309 rwhp. Which is pretty good. Stock LS1 with no mods with a manual typically dyno in the 300-305 rwhp. If they put headers on, tuned it would probably dyno in the 325-330 rwhp range. Hope this helps you understand.

[@justinguerrero135]

Didd you have problems with shifting after longtubes and tune? Visually and taking out nothing is wrong did you run into any problems in currently doing what i seen you have done

[@TheTallAbacus]

Fingers crossed for a 2015 Mustang with a turbo or two, 300+ bhp, and 33+ mpg. Winning.

[@skybluemarshall]

Please explain why you think a modded 3.7 Mustang will beat or run with a stock 2005-2010 GT Mustang (305hp - 315hp), but it will not beat a stock 02 Camaro with 305hp? You said that your modded Firehawk spanks modded 3.7 Stangs (and I totally understand that). But, Tappedurassout stated, these V6 Stangs can hang with a stock LS1, which is very similar in power to those older GTs, which you mentioned and you disagreed with him. What am I missing here?

[@NEVVEDGE01]

Props to Bamavol89 I'm glad one person hear caught that besides me. Not hating its just not realistic I had a 95' GT that was at least 385-400hp but only put down 310-315 depending on conditions.

[@ThePantyDroper]

I didn't buy my truck to race, I bought it to haul stuff. I'm running a tune for towing. I was just explaining how easy it is to get decent power out of the new V6

[@patrickpp14]

the "before" dyno had stock tires but the "after" vid had those saleen reps with pretty meaty staggered tires..Could that have mad any difference as far as power considering the fact that u simply have more tire than before?

[@croneous]

Wow that's about 60 hp gain all the stock dynos iv seen were 255 rwhp that's impressive just need a throttle body and one piece aluminum drives haft and I bet you can get 325 rwhp maybe more I talked to American muscle and they said with all those mods plus the ones iv mentioned they've seen anywhere from 360-380 at crank with those v6

[@Ag-gp7kp]

Gregg Lange I highly doubt a driveshaft is going to alter hp. The good thing about upgrading your driveshaft, is that it won't crap out on you when your driving like a bat out of hell. I do have a single piece aluminum on my car.

[@croneous]

Ag ik it won't add hp but it will lessen rotating mass which could effect the loss between the crank and rear wheels for every 20lbs rotating mass it almost equals to 100 lbs mass stationed weight

[@Ag-gp7kp]

huh. I did not consider that.

[@spawn302]

Also, stock v6 mustangs are limited to 120 mph electronically because otherwise the driveshaft would break. Put that aluminum drive shaft and make yous have Z+ rated tires and you're good to go to remove the electronic speed limit barrier.

[@skybluemarshall]

So how much did all those mods cost? I might be wrong, but I think a super charger kit will give you everything, including a tune, for about 5K. Granted, it probably wouldn't sound nearly as nasty as this car does, because that price doesn't include any exhaust mods. But, a SC would put at least 115 more hp to the ground and I've even heard a SC can pass California emissions. Your set up was probably close to 2K after tax. One traffic stop in Cali and you'd be wrenching all that stuff off

[@Ag-gp7kp]

You gained some hp, but lost some torque. Did you stick a different rear end differential on it?

[@patrickpp14]

what is your car lowered on? what parts specifically? Im only asking because i want to lower mine and dont know what to get?!

[@skybluemarshall]

What can I say, I love the leather seats. I've never had Leather interior. I like the throwback look and the perforations breathe well. I like the badging and the grill of the Pony package. I like the upgraded stereo, with steering wheel mounted controls, bluetooth capability, USB connectivity. I like paying almost $70 per month less for Insurance and $65 less for gas. I like getting 30mpg (33mpg) at best) and going over 450 miles without having to stop for gas. GTs are great cars but not for me

[@jeremyshoemaker5515]

I can guarantee that with a stock sealed airbox, a highflow catted x pipe, and chambered mufflers this car would have made more power. It would have definitely had a better torque curve as well. Louder is not always better.

[@jesuswithcheese]

did you get a copy of any of the actual dyno plots? can you post those?

[@agjr85]

How much less HP do you think w/o the BBK X-Pipe, just headers and other items? I'm very tempted now. I'd be happy with 300RWHP

[@98MAzdaMilleniaS]

You are not considering the fact that it lost 6(!!) lb-ft to the rear wheels although it gained 23 whp. & this v6 only makes 270 to the rear wheels with full bolt ons and tune ?

[@ThePantyDroper]

I have the F150 with the 3.7. I guess it will upset you to know that with an intake, exhuast, and custom tune, I am making roughly 350 to 360 hp and around 310 torque.

@butterpoop its been done before... SVO. Hell if the turbo is big enough, people wont complain

[@iXetsuei]

@Mr6Stang But hell, I'll be nice and explain why an X and H pipe have no benefit to a V6 motor. V6 motors all have firing orders of LRLRLR. This means that through both pipes of the exhaust exhaust flow is equal. With a V8 though, the firing order is LRLRRLRLLRL. This means that double the pressure is coming out one pipe and the other pipe there is no pressure, and vice versa. This is where the X and H pipes come into place, to balance the pressure because of unequal exhaust pulses.

[@skybluemarshall]

Sorry, I just realized, he said his SS put down 305 RWHP stock, not 305 flywheel HP. Now I totally get your statement. The older SS Camaro out powers the older GTs and it has more torque than modded 3.7 Stangs and newer V6 Camaros. But, wait a minute, now I'm confused again. Why did his stock Camaro get 305 RWHP and your Modded Firehawk only gets 309 RWHP? I need to go read up on those early 2000s Chevys. Now I''m lost again.

@jrand13 350 at the crank. they downplayed it to make the vette's 350 look better, but the vette's 350 is true for all. plus, try finding an LS1 that hasn't been modded on the street.

Where in florida did you do the dyno runs

[@biscuitninja]

I'd put some cats in there and throw in a rear gear. After that, some lightweight wheels. Taking away weight is alot easier than adding HP. I've done both.. but one is certainly more expensive than the other.

you know the things I like better about your mustang. even though the interior is all plastic, I like the style much more than the new stangs. Your trunk is also much much larger than mine and it feels like the tq is down low on the 4.0 where my peak doesnt hit till about 3800 rpms. anyways you got a nice car that will last a long time

I may sound dumb but do gears 3.73 or 4.10 help out on hp gains at all? I dont think so but someone told me they do lol

[@ADD8oi]

Because it makes 300+hp stock and is a great platform?
