2015 5.0 fuel system?

[mod mod t56]

What do you know about the 15 5.0 fuel system? fuel pump size? Injector size ? And location ? I took the cover off and didn't see a fuel rail? My first gdi car e 85 compatible? stock compression and timing? Any info would help ....thanks in advance

The compression for the V8 is 11.8:1 (sorry, that's all I got).

Here is some more info:

5.0L V8 Engine
DOHC 32-valve V8 with CVVT
420 hp @ 6,000 RPM (Premium Fuel)
383 lb.-ft. @ 5,000 RPM (Premium Fuel)
11.8:1 Compression Ratio
Gasoline Direct Injection (GDI)
Tuned Intake System (TIS)

there is a video floating around on the GDI system on the V6, I assume it would be similar to the V8. The fuel rails look like they are deep in the V of each engine, under the intake manifold so they are very hard to see. The high pressure pump is on the driver's side valve cover and is driven by a lobe on the camshaft.

And don't use E85, scary things will happen to your engine...

BIG NO on E85

Why not? All you need is a pump, injectors, a tuning solution, lines, fittings, and very little else!

I run e85 om my cobra ...with tune and e85 compatible pumps injection. Made 120 rwhp with more boost and timing....good times. ?.im not try I ng to do all that if its just a tune ....and dont really want to pull the intake to on tap fuel line ....fml ....no easy way to do this....gurr. ...where did you get ur info ? Any one know if r spec headers fit the 15? Any real power there ?.. any one run custom exhaust with good results orjust the off shelf magna flo? I thought nitro would be eazy 75 hp ....I guess nothing is eazy ....dammit

Made 120 rwhp with more boost and timing....

Huh?

 

[Aquineas]

Huh?

120whp delta between stock and stock + boost + timing adjustments.

 

[amartz]

120whp delta between stock and stock + boost + timing adjustments.

That sounds a *whole* lot better. I wasn't terribly impressed with 120whp!! Now 420+120, that's a different story!!

The e85 is on a 03 cobra 590 on 93 octane. 710 on e85. ?..more boost more timing ... my gen 2 5.0 is stock at the moment.... I have brembos slotted drilled rotors and
ads waiting to go on along with a zex wet kit .... but not looking to pull the intake. Was hoping to tap in to a fuel line or something accessible

your issue is going to be tuning. these ECUs are notoriously difficult to crack. I have a Shelby GT500 and looked into going E85 but decided that at 730 rwhp the chassis was basically maxed out and adding more power would simply make the car worse.

I have modified my Genesis extensively and am currently working on some one off engine and performance mods that I can't share much about right now.

Good luck - hope it works out.

My 03 is heavily modified and I've read that about the Genesis computer that's why I was looking at the nitrous wet system I figure I could get in hundred horsepower without a tune... ps do u track ur gt500 ? What tires do u run.....

Great tuning video by Steve Dinan.

Good video

The engineering videos on drive are always very informative.
