2011 GT500 whipple 2.9 dyno numbers

[JUST TRY 03]

i had the guys from modular depot tune the shelby today. i installed the whipple 2.9 kit from lethal performance. i also added an afco heat exhanger with fans, and ARH long tubes with a catted mid pipe going through stock mufflers. With the tune from lethal i was making around 656.

At the end of the day i ended up with 697.50 and 603 lb/ ft of torque.But we found out my stock fuel pumped maxed out at around 5500 rpms so we set the rev limiter there for now. I ordered a kenne bell boost a pump which will be installed next week as well as a smaller pulley

Nice number's, cant wait to see what it does when its not starving for fuel.

 

[JUST TRY 03]

yea i ordered the complete kit from lethal, i called and asked them if a fuel pump was needed and they told me no over and over again, the first pull on the dyno the pump was at 97%. hopefully with a BAP ill be over 700

I was there today with my 04 Cobra. I seen and heard your car. Nice ride. I over heard your conversation with the guys a MD Speed. The pump situation sucks. Good luck with the BAP and Pulley.

yeah I'm maxing mine out also. I'm going to go with the Fuel Pump assembly over the boost a pump. I made it over the 700hp mark but I think the injectors and throttle body really helped it out. Your almost there though. These cars seem to love the 2.9

i looked into buying the dual pumps from ford racing but apparently they dont sell them. they only sell them with the 2.9 whipple kits. i would have rather went with a new pump but im hoping a BAP will work

thanks. your cobra looked good as well, what did it end up making?

Nice numbers. What injectors are you running. Also call Paulshp.com if you want the pumps that come in the frpp kit.

 

[rtvickers]

My best was 546 hp. But it is way too lean. When I go back there going to do a tune and maybe switch to a 3.00 upper. Well see what that does.

I heard them driving your car in the lot. Sounds pretty wicked. They were talking about that pump after you left. They called someone and tried to see if they could get one and lady told them they weren't selling them. He asked what if he needed some replacement parts in the pump. She said sorry. Sounds to me like its only a temporary thing. Hopefully they can get it figured out for you. Good numbers.

What size pulley are you running and how much boost were you making?

+1 OP, what injectors are you running?

im running the stock whipple pulley for now with 72 lb injectors, i believe they had it up to 15 lbs of boost

Dont worry about the bap. Its been proven time and time again to be a safe way to get the fuel you need to the injectors without having to drop the tank and install new pumps. The chevy guys use them too with all their blower kits. Its a great product.

 

[Black'03GT]

How does the car sound with the new LT/midpipe and stock '11 exhaust? I'd love to hear a sound clip or video.

you dont have to drop the tank to swap the pumps in these cars.

[strongs_2009]

Agree just lift teh back seat up and the hat is right there. The BAP is good I have been running one for awhile but I have also upgraded my pumps with the ford gt pumps.

[dirtyo2000]

shoot me a pm but you will be suprised what you can do these days. The boost a pump is always a sure way but I like to keep everything plug and play and add as little to the car as possible.

it sounds pretty good, i have the long tubes, catted mid pipe and stock axle back. its alot louder than i thought, they had a 10 gt500 with magnaflow axle backs there, i liked that sound better because it was more deeper and sounded like a muscle car. to me my car sounds a bit raspy at high rpms

 

[bull3441]

in Lethal's defense, i'm sure they told no on the pump as to there tune. you maxed out the pump with retune. never cut corners on fuel delivery, get the larger pumps. nice #'s

The BAP works fine.
