Anybody running CTSC with Comptechs FPR and Factory injectors? Whats the max psi before the factory injectors and Comptech FPR starts to fall off?

 

Buy my 440 injectors for cheap and max them out!!!!! I'll sell them to you for 150 shipped

 

I have the RC 650s but I don't know if I really want to use them. If I could get away with stock injectors, I think I will go that route. So I need some info..been searching but the search engine here is kinda tough to filter out other data. Max boost on factory injectors, comptech FPR and Walbro 255 pump anybody??

 

Max SUGGESTED is 7 psi...I did 10psi but a had a boat load of methanol spraying also, I don't suggest this, I did it just to see and later removed that setup.

 

Any other variables to consider such as using a piggyback like a (V)AFC(2)/NEO, or meth?

s2000junky is pushing the stock CT setup to its limit, but he's using the variable I mentioned. I think he's at 10 psi?

 

Thats just the info I was looking for. Thanks!

Now if I do use the 650cc injectors, would I need some kind of EMS to control them or would I still be able to use Comptechs RRFPR? Just wondering, I doubt I would go over 7 PSI without a standalone and supporting mods to go with it..

 

Yah I have a VAFC2 connected already and a wideband set up soon. I wanted to see the max PSI I could run on with the factory injectors and comptechs RRFPR. Then I would basically set the FPR to a acceptable AFR from VTEC to redline and trim the fuel with the VAFC on the lower revs.

I heard it was dangerous to cut to much fuel with the VAFC because when you pull fuel it advances timing??
