Which would you rather own: Turbo V6 Mustang or V8 Mustang

[SeanPlunk]

Based on announcements over the last couple days regarding engine choices for the F150, it appears Ford has two engines with basically the same horsepower and torque numbers. The first engine is a 3.5L TT V6 that is supposed to have 400hp/400tq (in the trucks at least, the car version has 355hp). The second engine is a new 5.0 DOHC engine (called Coyote) also with 400hp/400tq. The rumors are that both engines in some trim will eventually make their way into the Mustang. Assuming this is true, and everything else was the same (transmissions, rearend, price, etc), which car would you rather have?

It's a tough call for me. I love the idea of a new 5.0 Mustang and I bet it's going to sound amazing, but I think the mod potential for the TT V6 would be incredible. I bet with bolt-ons it would be easy to have a reliable 500hp out of the V6. Given the choice (I know this is blasphemy), my vote goes for the TT V6. For purposes of this poll, assume you are choosing a starting point and would mod each car according to personal preference.

[Vettezuki]

My guess is the TT has considerably more power under the curve (i.e., peak torque at lower revs).

Assuming both made 400/400 and both cost the same I'd choose the 5.0 then add a centrifugal to it. But if the V6 was less money, even with say 355hp, I think I would choose the V6.

Yeah, the reason I went with the V6 TT is because of the forged parts, and I figure you could easily get to 500hp with around 1k in mods. The 5.0 obviously wouldn't be forged and putting a blower on would be more money, but ultimately it'd be a lost faster :judge:

[BRUTAL64]

Easy, V8.:motorsmile:

[Chate]

The mustang II from (iono what year, i'm just a kid) signalled quite an outcry for not having a V8 option right?
I think that magic number 8 is key to american motorminds...never heard of a "muscle car" with less than 8 cyl, so dunno how well that'd go over with the enthusiasts...

But yeah, being the R34 lover that i am, and with all other components being equal, I personally would go with the V6 TT for the same reason as above, more boost capacity out of the box.

There was no outcry for a less than V8 Mustang II, it was a function of the times and government policy (somewhat indirectly). This was the beginning of the hippie-tree-hugger era. It was bashed by enthusiasts of the time.

BTW, the R34 is an I6 not a V6. They are quite different animals. I love many I6s, including the Skylines and Silvias of history, but also some of the British versions, especially the vicious TVR. Not as much of a fan of the V6, though I'd probably take a TTV6 over an NA V8 in a production Mustang. Ironically, I think I'd go the other way in a Vette. :huh:

[Chate]

Right, outcry AGAINST the v6 is what i was suggesting, right on with the I6

[SeanPlunk]

It looks like this may actually happen, although it sounds like the TTV6 will "only" be rated around 365hp.

[SeanPlunk]

Oh, and I'd still rather have the TTV6 for the record :pot_stir:

[BRUTAL64]

V8.............that's my final answer.:D

[Vettezuki]

Will the TT be all forged from the factory? If so, it's kind of a no brainer for me if just power in an otherwise tubby car is concerned. Now give me a light car, and a 400hp DOHC 5L NA (Coyote) would be my choice.

It's not forged, but neither is the BMW TT either. With the direct injection it doesn't seem to be that big of a deal.

It's a different upper limit if you want to tinker. Then again, comparing much of anything to what you can do with a stock Supra motor is not really fair.

[enkeivette]

It's so close for me it would depend on how the engine was setup. If the V6 didn't get into the boost at part throttle, I would take it. It would have better gas mileage and be more tuner friendly.

But, if it was ultra low compression and it needed boost just to get from one stop light to the next, I would go with the V8. If you're always in the boost your mileage would be as bad as the V8 motor and you'd have to deal with the added heat and the added cost to service the motor.

The Ecoboost has 10:1 compression and turbos that spool quickly :thumbs_up:

[BRIAN]

With a 3.5L on a twin set up I'm pretty sure that motor will have spool almost instantly. Of course there are many variables but if they want a smooth power band it will be quick spool, more than likely the reason for going with two snails :)

Exactly. Plus, I hear the motor is good for 450hp easy :whistle:

[BRIAN]

450 could probably be done with just the usual drop in intake, 3" exhaust, and a boost controller. Reliability is a different story, all in the tune.

Very true. I've heard tuning the SHO is difficult at this point :huh:

[94cobra69ss396]

All new cars are difficult to tune until they figure out the code. Give the aftermarket a year and they will have hundreds of tunes. I did read though that the turbos are really small and that is going to be your limiting factor.

True. I have also heard the other limiting factor may be the transaxle. In the FWD setup I guess it can't handle the torque. Now in the Mustang though it wouldn't be a problem :bigthumbsup:

[BRIAN]

Yeah the new SHO looks nice from a luxury point of view, I don't think I would want to mess with tuning a ride like that in the first place. Although I don't doubt the 8 year old's of today will be picking these up and modding them blindly 10 years from now.

[Leedom]

A turbo is quickly pumped up in HP but has a lower ceiling. Bang for buck can you really go wroing with the TT V6? Did I just say that... must be the captain (moragn) talking.

[BADDASSC6]

?????? Why wouldn't it be forged???? The 4.6 DOHC had forged internals????


Here is what it comes down to:
Budget build go witht the six get a boost controller and ditch the cats.
Want to dominate go with the 8.

[eric97srad]

Given the choice (I know this is blasphemy), my vote goes for the TT V6. For purposes of this poll, assume you are choosing a starting point and would mod each car according to personal preference.

Yes, blasphemy.

Bang for the buck factor aside, I'd still have to go for the V8 in the Mustang. It's only logical... Now, take that TTV6 and put it in yet another attempt at a new T-bird (something similar to the late 80's early 90's SC) and I could go that route for the right price.

I just read an article in Popular Hot Rodding about the EcoBoost V6. Turns out that it has a forged crank but the rods and pistons are cast. Even with those they are still using 10:1 compression and 12psi of boost and it can run on 87 octane. It's all because of the direct injection. However, for added safety the Bosch ECU can pull out up to 20 degrees of timing.

It also said that the turbos are 48mm Garrett GT15s. They are said to be capable of 200hp a piece so it looks like peak hp will be around 400 at the flywheel unless the turbos are upgraded. I'm not sure that you would want to go any higher than that with cast pistons anyways. Hopefully they will offer a higher hp version later on that has forged pistons and rods.

Great info - thanks!

It's interesting though, I have heard from a couple Ford insider guys that the EcoBoost is good for about 450hp as is. Maybe those mules had bigger turbos :huh:

[trymev8]

if i were to buy an american car it would have to have a v8. It is a heritage thing in my opinion.

I think they made another engine like that. If I could only remember which one?:smack:

[SoCalC55]

Putting down substantially more HP with far less money invested is nice and all, but a mustang without the V8 noise.... is no mustang at all...

I agree with you. V8 -- Mustang is jthe only way to go.:p

[jedhead]

V8. Then add turbo's

More Mercedes should have loud exhausts. I heard one going down the street the other day, had to look twice... sounded sick. Kind of like a new Vette with Borlas.

[SoCalC55]

Had to have been a 63. By doing the same 2 mods that ive done to mine (reonator/ secondary cat delete) you can sound like this

YouTube- Optima Invitational Road Course Burnout Start

[enkeivette]

Didn't sound like a 12, sounded like an 8.

I wouldn't want the TT12 btw, I can't image how expensive it would be to service that motor. Give me the supercharged 8.

One was trying to race me in traffic, I wanted to give him a taste but there was no room on the 57 at 5pm.

The new 63 series are not a twin turbo 12 it is a n/a va with as much power as the old supercharged v8

[SoCalC55]

^yep

The 65s are the TT V12s

63s are a N/A 6.2

I like how the Z06 that goes just after him in the video sounds quiet =p
