4cy Turbo's in Muscle Cars

My FIL has a gorgeous V6 Stang Convertible in a very nice deep blood red color. It has a specific package on it to resemble the V8 model with identical exhausts, tires and rims, etc.

I must say, I was quite impressed when I nailed it! Very respectable, and would definitely smoke a lot of so called "fast" cars.

Very respectable in the ragazines, too. Folks running unreal quarter miles in these things with minor mods. Real V8 territory!

Don't know what others are talking about, those lil V6's can really fly these days...

Probably because it's programmed for max fuel economy, so it up shifts to max gear very early. Another reason to opt for the manual trans.

The SVO still had a solid rear axle but the suspension was tuned with special springs and Koni shocks. I think there were some later SN-95 Mustang Cobras that had IRS but no Fox Mustangs ever had it. (moved)

You may be thinking of the Thunderbird from the same era. EDIT: Nope, looks like you may be right.

Fixed my earlier posts since I couldn't edit them now.



1984 Mustang GT Turbo. Real car.
 
Wonder if the ecoboost Mustang will actually have any real turbo "boost"? I've driven a few ecoboost vehicles and they didn't have any turbo boost at all that I could feel or hear. The turbo cars of the 90s would throw you back into the seat as soon as the boost kicked in.

Older turbo engines had low compression ratios and terrible turbo lag. So the engines went from pathetic power to maximum power. So they felt like a rocket only because they felt like a slug before the boost kicked in.

Newer turbo engines have high compression ratios because the fuel and ignition timing is very precisely controlled. So the engines have good power even before the turbo spools up. The effect doesn't feel like your being thrown back into your seat but the speedometer will tell you otherwise. The engine drivability is a significant improvement over those 80's and early 90's turbo cars.
 
My 2700 pound, Honda S2000 has a 2.2L engine and an aftermarket turbo setup. It makes just over 400RWHP at 19.5 lbs boost, which spins both rear tires wildly. Better behavior at 385 RWHP/17.5 boost, which is where I drive it, as it remains controllable in 2nd gear.

Short of some absolute magic, I'd never mount my "old school" S2000 engine in a modern, heavy Mustang as it's just too laggy. However, I know Ford does a great job getting early and ultra responsive boost with the direct injection engines. I can't wait to drive an EB Mustang. I'd guess it's just fine and a whole lot of fun.

Interesting dyno chart. Looks like the engine will be producing plenty of torque at any reasonable RPM. I like it already...

Some boost management to flatten out that torque curve and it will be near perfection from a "feel" point of view. That would require an increase in boost at 5000 RPM. So many people hate to do this, but it works wonders with certain engines. Ford did it years ago, with a boost jump at 4500 RPM to keep the torque curve and volumetric efficiency flat.

At the moment, the better tuners are getting just over 500 RWHP from the EB Mustang with a few critical mods... (hint, bigger turbo)

Not sure about seeing that in a Mustang II, but I bet there will be plenty of Ford (and other company's) sedans with that exact setup.

Car and driver did get a higher skid pad number at 0.98G with the 4 cyl than the V8, at 0.95
If the car lost 500-600lb it would be quite the sports car!

A few reviews I read that was the statement made. With the 4cy turbo it turns the Mustang from a pony/muscle car into a sports car and competes in whole different class.
Interesting.

Well, the big problem remains. At 3657 pounds as tested even with a stick shift, the Turbo Stang is ridiculously heavy. Then there's the sounds it makes, even with Ford pumping in fake noise through the stereo speakers.

But a little work could make it a great car...
 
What's not to like? Beautiful pony car proportions combined with modern four pot turbo for economy. Just don't open that long slick bonnet.

I can't figure out why cars like the Mustang and Camaro weigh so much...they should be able to trim A LOT of weight off of these things...

Hahahaha a Prius that sounds like a V8

One could do the same with the Mustang 4 cylinder turbo. However, a well tuned turbo 4 sounds great IMHO.


Agreed. Alfa has one I like in the 4C (http://www.caranddriver.com/reviews/2015-alfa-romeo-4c-coupe-test-review) but most, including the Stang, sound like a moose is being strangled or something...


Alfa just revealed the new Giulia QV (bound for the USA by 2017): 3.0 V6 biturbo 510 bhp, 3300 lbs, RWD. Carbon fibre axle, bonnet androof, extensive use of aluminium, and likely the next Dodge Charger will be on the same platform

People like stuff and stuff adds weight.

IMO that will never happen. Way to expensive,exotic platform for Dodge. AR is now positioned alongside Maserati.
