Fuel System for 07 Gt500 with 2.3l TVS looking to make 700-750 RWHP ???

[builttodrive]

I am in the stages of a rebuild on my 07 GT500 that will be getting a Ford Racing fully forged short block and I will be re-using the 2.3l tvs set up with a 2.6 Metco pulley. The stock sized Ford Racing balancer is currently on the old motor but I was thinking of going to a 10 or 15% overdrive pulley to make a little more power this time around. I sold my stock injectors and will be going to something larger but not sure what exactly. I also scored a FORE fuel rail set for a decent price and will be installing those. My question is what recommendations do people have for what fuel system I should be using for the car if I was looking to make 700-750 RWHP with the car. Either with 91 pump gas or E85? I'm wondering what injectors and what pump set up?

I'm using the Ford #56 injectors from the 13/14 and a BAP. My TVS, 2.4 pulley, 10 % IW, LT's and L&M TB I put down 737 RWHP on a DynoJet. E85 would require larger injectors than the 56's.

bap and 72 or 80 your good to go above 800

but why ford racing short block ?

it has a very low compression pistons 8.1 to 1 you will need more than what the tvs can bring to go above 700-750 rwhp

You'll need I'd 1000s with the kb 20v bap. That will get you over 700hp with E85.

 

[Joewee500]

Will ID1000s last with e85? I know the ID1300 are e85 specific but will the 1000s have issues in say 20k miles of e85 use? I'm hoping for 700+ when mine gets back together but didn't know if e85 was an option for me.

It was supplied to me by my Ford dealer as the car had problems right after I purchased it. Also it is a great shortblock bang for the buck. It has forged H beam rods and forged pistons the stock short block does not. Also 8.1 isn't really that low compared to the 8.4:1 stock compression ratio. It may take a bit more than a stock motor to get to the power level but the car put down 640 on 91 pump gas previously with the 2.6 pulley and stock fuel system, exhaust, throttle body. Besides the 2.3 tvs and frod racing 113 mm intake the car is basically stock with a VMP tune. I'm sure if I added a bigger throttle body and some long tubes with a 10 or 15% overdrive balancer it would pick up some power.

VMP has suggested adding a dual boost a pump and ID1000 injectors tuned for E85 this time around so I would assume it is an ok combination. I just don't know enough about E85 or how much power I can really make on 91. There aren't any stations that offer 93 at the pump in my area.

I feel your pain. All we have is 91 in the 3 state area and only one E85 in the entire county.

 

[NightRide]

If e85 is available go that route, big hp numbers on 91 equals kaboom. I can only get 91 as well but have a torco tune for the fun nights.

Op you put down 640 with a stock throttle body and a 2.6? Those are nice numbers!

Yes the car put down 640 hp and 624tq with just the 2.3l tvs, 2.6 upper pulley, ford racing 113mm cold air intake and a VMP 91 tune. It also has a C&R dual fan heat exchanger but everything else on the car is stock.....engine, fuel, and exhaust related that is.

Mods are in signature. 80lb Injectors, KB Dual BAP.....

That's nice man. I'm hoping to get a throttle body after the first of the year and put down at least 650rwhp. I'd be happy with anything over 650rwhp+

Can anyone tell me why E85 is superior? We have a Cheveron hidden in the woods near Napa Auto-Parts that sell E-85 for 2.75 a gal...can anyone run this? I know my bros Expedition w\ Flex Fuel can, but do you have to convert your car\tune it with ours? Confused as to how racing with E-85 also means less chance of blowing up the motor if trying to meet same power? :shrug:

Simply put, E85 can withstand more boost/compression before detonation, so does higher octane gas but E85 is still better.
You will certainly need to convert your car to work with E85 because it wasn't setup for it.

Well now I'm annoyed my brothers flex-fuel Expedition 5.4l loves e-85 I guess I'll have to look into it, for him the benefit even stock isn't worth the cost, let alone finding a place that has it.

I see that some highs this week in Sioux Falls, SD are below freezing and lows are in the single digits. Unless you are only a warm weather driver, check with E85 owners who are starting engine in the cold. The few I know say it's not good in the cold.

I put the car in storage over the cold/winter months. They aren't exactly snow machines and the chemical that gets used to melt the snow off the roads during the winter months is pretty hard on vehicles so we store our hot rods to keep them nice and once spring rolls around we bring them back out.

e85 ID1000's and our fuel pump booster.

91 with Torco ID725s and no booster needed.

700 is the limit for 56's/booster. We've tested it with all sorts of injector/booster/fuel/boost/power combos.

I run a set of ID1000s and a booster on my car and at 23psi and 750 rwhp (no, not pump gas) the injector duty cycle is around 70% and the pump DC is a little over 80%.

No, you won't/can't more than once, make 700 on 91 octane pump gas.

Thanks for the info BJ. I am limited to the 2.6 upper pulley on my ford racing TVS but was considering a 10 or 15% OD balancer swap in my rebuild. What would your guess be for power out of the car with the current set up with the Id1000 injectors, boost a pump and E85? I'm sure I have limiting factors with the stock exhaust except for my SVT1 mufflers but what kind of power improvements would I see from a set of long tubes and a larger throttle body?
