Kit for adding extra fuel pump???
#18
HI,I think John D. from SpeedTech runs 2 pumps with a stock intake set-up??Maybe he can step in....Thanks
You can see it here...

If you are running out of fuel and you want to increase the the pump output, you could use the "electronic" pump boosters made by Kenne Bell or Mallory. These units increase the voltage to your stock pump thereby increasing the output of the pump itself. It can also increase the voltage in a boost dependent manner, normal voltage at no bost and then increase the voltage with boost. This prevents your fuel constantly running high fuel rates with high return back to the tank via the fuel return line. In addition, if your fuel return line is too small and you are supplying too much fuel at all times, it can actually increase the fuel pressure at idle and make tuning a little problematic. These Boost-a-pumps have been used along time and I would think that it would be an easy solution. The claim is that it can increase pump output by 50% by increasing the supplied voltage and before you think that this is "ghetto", the Koenisegg uses the Kenne Bell Boost-a-Pump

injectors alone are not enough ....
I know you dont have a blow thru....
Yes its doable but its a a pain in the butt making it fit.... thats why not too many tuners have this option available.. if any...
As far as one blowing vs the other.... then running on one only.... we hook ours up to the stock relay....

can you please explain how "As far as one blowing vs the other.... then running on one only.... we hook ours up to the stock relay...." stops one pump from failing mechanically?

I see you're running 58# injectors... what is the theoretical (hp) limit of your current fuel system?
Thanks!

The 58# injectors were done in 2008, and need to be replaced with 72# if I want to make big numbers. I am actually more concerned with moving my spool down a bit, and hitting full boost earlier. New inlet pipes from markski are incoming!
