PLease tell me a safe psi

[DSM-Talon-John]

Ok I want a safe psi but I want it to be fun and a noticable change from my tiny t-25. I just bought a evo3b16g, I have a walbro 190 on my car right now, I have 650 injectors but wont be putting them on till I get my safc. So with just the 190 fuel pump whats safe to run? My mods are in my profile.

Also My car has been fully tuned up besides spark plug wires which I just bought, so it is running in tip top shape with 73k on it.


Ok and once I get the 650's on and tune it reasonably good what should I get out of it?

14psi should be safe and timing friendly maybe 16psi.

Get a logger, and start at 14psi or so, and turn it up until you see knock then back it down 1-2psi. This is ofcourse after you get the S-AFC.

What will 14 psi feel like compared to the t-25. Will there even be much of a difference? Im hoping to get some injectors hopefully they show up? So 450 injectors can only give you around 14psi?

I agree

It's not just a matter of injectors. The factory setup is good for up to about 14-15 PSI. Since you've got the 190 lph pump, you're part of the way there. Above 14 or so PSI the fuel pump alone isn't enough. You need to get those injectors in, as well as some sort of fuel control. An Apexi SAFC-II is a good answer to this problem. You can then adjust your own fuel and air ratios, and compensate for increased boost. I did read your post, but build your engine up to the turbo you bought. I have the same turbo, and I have to do these things in order to take real advantage of it. Good luck man!
