What is everyone doing with their fuel pumps with forced induction cars. I'm being told that if I wanna get any more out of my Whipple I need a fuel pump upgrade. The Shelby 500 pump is pretty $$$$$$$$ and it has to be re-wired to fit the GT. I'm told boost-a-pumps aren't the best option either because it increases the voltage to the GT pump (which is what you want) but it can cause the pump to burn up eventually...........Any ideas guys. I feel like an idiot here. I just need some sound advice.

 

I'm using the Boost A Pump; I haven't heard much about reliability but I do know that Brenspeed sells alot of them and if they were having problems, they wouldn't sell them. I think ultimately twin pumps from the Ford GT or the GT500 would be awesome but $$ is a killer......

 

What's the next pulley bump for the Whipple? 10psi?
You do that, I am guessing you need to do the fuel pump....

With JDMs Saleen set-ups, once you hit the 3.4 inch pulley (9.5lbs boost) then I believe they tell you do do something with the fuel pump.

I'm running the 3.6 so I am good to go with the stock pump.

We have a great price on that BTW...

Good luck!!

CR send me a PM on the price for one. Also I need to know how hard it would be to wire in an extra pump (Ford GT pump) to my existing stock pump. I NEED MORE FUEL!!!!

 

If I remember correctly you have the non intercooled version Whipple, if this is true you will need a lot more than just fuel pumps. To go much past what you have now your IAT without the cooler will put you into detonation very quickly. I think you can add the intercooler to your setup but I’m not sure. The Boost-a-Pump would be the easiest way to increase your fuel quantity but the GT500 pumps would be the best in the long run.
