I talked to the guys at CSP yesterday who did my car, and they said that I was at the end of my fuel system when the car made 557whp, is that even possible?

Procharger guy told us a while back that not every car can make the same power on it's stock fuel system, my experience and yours obviously support this over the blanket claims. Yes I am saying that if CSP tells you that your fuel is maxed, then I think that you should believe them. |

Do you have the entire LT4 fuel system hight to low(Injectors, HPFP, LPFP)?

Do you have data from CSP? Otherwise we’re guessing. Need to know: 1. Low side pressure 2. High side pressure 3. Injector pulse width

Sorry, I did not notice your sig about the LT4. But, if you only have the hpfp changed, perhaps your low side pump is falling? You could ask CSP what you need to fix before pushing it further.

You can certainly benefit from a Standard rotofab and 95 mm tb. https://jannettyracing.com/products/...-including-z06 If you add a JMS fuel system voltage booster your fuel system will support 580 RWHP but that's it. I recommend adding our LT1 fuel system upgrade package which includes the JMS https://jannettyracing.com/products/...2018-camaro-ss

That is your issue...you need the entire LT4 fuel system high to low. Just changing the HPFP gained you very little.

I knew I should've told them to do the whole thing, I wonder why they only suggested the high side.. and the blower has to come off for this doesnt it?

Doing the HPFP and not the injectors does not make much sense IMO. The LT4 HPFP runs a higher pressure that the LT1 injectors are not supposed to run. Complete mismatch IMO. Maybe someone knows something else that I’m missing?

I’m being told that my best option is a better cam, and that the high side is the one that’s running out

LT4 in tank with JMS LT4 HPFP with cam LT4 injectors That combo will get you in the right direction to make power with a blower.

He’s what they’re saying. Me: I meant like do you think I’m running out at this level because I only have the high side done? No injectors/low side Them: No, that is what was running out, not the low side or injectors. They are independent, If the low side was dropping that can cause the high side to run out but the low side was holding steady
