The problem is our cars don't have a bucket per say in the tank its a fuqing donut with lpfp stuck in the middle. So unless we can fit a bucket in there or some sort of alternative I don't know. Showtime says spool got something but they never replied to me. David Shoup said he will check for me and get back to me so let's see. |

If someone could answer a dumb question:
I got an upgraded hpfp (spool fx150) when I got my ps2 although I'm only on pump - no e - is there any point to upgrading injectors (and tuning accordingly) on a setup like mine?

No point... these are really meant to be for people who want to push more ethanol.... you can probably push more fuel but can't change the octane rating on pump gas.

After the ps2 it was worth upgrading the hpfp in order to push more fuel - even just pump gas - and add more boost...at this point I don't understand whether the stock injectors happen to be the constraint or something else before something more could be done with just pump gas

Wondering if that's sort of just the limit for pump gas, or maybe if it just so happens that then the injectors become the limiting factor and this upgrade might actually be worthwhile. But, small chance, I figure.

yes everyone is right. In order to reach anything above 21psi+ you will need a HPFP. Stock cant keep up. Especially if your running e85. The more e85 you run the more strain you put on the fuel system. Especially the primary LPFP. Even when you have the LPFP and HPFP you then will put a strain on the fuel injectors. When tuning you want to keep the LPFP happy. The stft must stay between +5 and -5. You also dont want to max out your fuel injectors or the rail pressure will crash. Everything has to flow in accordance.
