Check this out i have a question if I have a vafc II and 550cc injectors. for my GSR TURBO do I still need a raising pressure fuel pressure reg? i have a greedy 18g plan on keeping stock internals for a while so 7-8 lbs will be tops so if i got the comp and injectors doesnt that do the job of a raising pressure regulator:dunno:

Using a "afc hack" will eliminate the need for a rising fuel pressure regulator. For 7-8 psi 500cc is kinda overkill unless you plan on raising the boost in the future.

thanks again bro
please explain the frequent use of the term "afc hack"
is it garbage or does it do the job safely:1zhelp:havent purchaced a fuel management system yet

I wouldn't call it garbage, but it is a "band-aid" however. It will do the just fine until you can invest in a good stand-alone. The "afc hack" is just using some 440+cc injectors along with the AFC or VAFC. To start with, you set all the points at -40, this will allow the car to idle with the oversized injectors almost perfectley. Then you can always dine tune it on a dyno. I got my A/F to a perfect 12:1 across the board in all rpm ranges using the "hack". It works fine for lower boost cars where it might not be worth spending $500+ on a stand-alone.

thanks for the explanation and guidence that will be a huge help with project:evillol:
I cant wait to join the turbo club rather go slow than make mistakes:dogpile:
Melting pistons and valves not on my list of favorites:headshakeor things to do. Rather add a 12 second time slip I'm in the 14's on a g-tech now
But today i was fucking with a turboed sohc, he seemed quick but there was no room in traffic on 95 sucks. Plus I saw a saleen mustang pulling people over, I dont know might be part of that damn agressive driving task force
