I have a h/c/I 06 zo6 , makes 551/520 stock short block , I have a 450lph pump and 80lb injectors on e85 , can I tap into where my flex fuel sensor is and pull fuel for a 50-75 shot safely ? Will be running a single digger nozzle n/x kit with the lingenfelter timing retard box , how much timing should be pulled for a 75 shot max , thanks

I had an OEM Z06 pump on e85 with a magnuson supercharger and a 125 shot pulled from the fuel rail. Made 650 uncorrected

Wanted to piggy back off this thread as not to start a new thread with a similar question. Can I use the stock pump without a BAP for a 100-150 shot if i up the fuel pressure to 72 psi base with the BMW 16147186454 regulator. Trying to avoid using a bap or a stand alone fuel system and keep the jet syphons

If your car is stock and you only have nitrous you do not need a bap or anything for a 150 shot.

We always recommend an aftermarket pump when pulling fuel off the fuel rail and you for sure have enough fuel pump. As far as timing is concerned you would need to know what total timing of the motor is when not on spray. Anytime you use nitrous we recommend pulling some sort of timing out of the motor. Since you will use the LNC controller you could start by pulling a few degrees. But you must know what your base timing is before pulling timing. You will sort out the fuel first with the wideband then you will work on the Ignition Timing map. I recommend you switch to a NGK BR7EF non projected tip spark plug. This plug will will be good up to 150hp.
