Stock LS1 Fuel Pump Limits?
Stock LS1 Fuel Pump Limits? At what power level should I need a higher flowing fuel pump? Im afraid my stock pump is holding me back causing me to miss out on a few ponies.
I dont have an accurate dyno sheet, but my car should be around 470ish rwhp.
I have Trickflow 215cc CNC heads, milled to 61cc, vengence racing vrx5 camshaft etc...
U better get a pump asap with that much power. I would not trust the stock pump over 400rwhp. That pump is not made to supply that much fuel and remember the stock fuel system is returnless so a weak pump will cause a ton of pulsing in the fuel rail cause its a dead head.

I vote if you have the $$$ and NO2 is in your future go with the 340lph and a hot wire kit.
Your 48lb injectors should get you close to the 550-600 hp mark.
The 340 would get you more in the end if you plan on some Go Gas in the future. I had a Walbro 255 with a hot wire kit and started to loose pressure around the 550 wheel HP mark. This was on a blower car witch will tax the fuel system a little more than NO2.

ill probably go with the aem 340 lph pump since more power is definitely in my future. Are all hotwire kits the same? and hopefully my 48 lb injectors handle a 100 shot without too much trouble.
i will go for the performance rx pump 255 with hotwire kit
i asked the same question on the fueling section , and the racetronix tech told me that with stock regulator you will see a significant increase in pressure , you will need a front mount regulator , also that the return line will get overloaded on stock system over 300lph pumps
i will go for the performance rx pump 255 with hotwire kit
