DOHC comes back? - ZR-1 Net Registry Forums

LGAFF · 05-03-2010

Anyone see the new Ford Mustang GT has a 5.0 that is knocking out 412 NA HP @ 6500? That equates to a 12.8 @110....not bad...will be interesting to see more specifics as the engine comes out.

Wonder if there any ideas we can steal?

fords been running dohc in mustang cobras since 96 and sohc in mustangs also since 96...I think the sohc came in the crown vic around 93-94ish? I love the new mustang

LGAFF · 05-03-2010

I know that, but they have not come close to 400hp without forced induction......fuel economy is better than the 3 valve 4.6....K&N did an independent test of the motor, coming up with almost 440hp.

Modular V8 came online for the 1991 model year.

Direct Injection?

LGAFF · 05-04-2010

Nope, direct injection was not in the budget.....although casting is set up for it down the road.

Aurora40 · 05-04-2010

Equally impressive is their new V6 that makes 305hp and gets >30mpg on the EPA's 2008+ highway test. You can get a 300hp 6-speed manual and a warranty for about $23k sticker.

They also have a V6 performance package that adds the GT suspension, but it isn't out yet. I assume you could get that on a base coupe for a real performance bargain, but who knows.
