Return Line PSI - SRT Forums

Adionik · 10-10-2009, 04:51 PM

Just curious to what those with return lines have their fuel pressure set to

I left mine stock after installing my return line because I was too lazy to tune all over again

Boost base only, this seems to work the best with the DS software. You can do a manifold based set up, but tuning the transition from 0 vacuum can get a little tricky.

Got mine setup 58 psi stock with the boost reference hooked up and I pulled almost 40 percent and it was in the 10s and then I added meth and now its like in the high 9s and 10s

Need to get a tune bad.

Mines at 58psi also with 1:1 regulator, without the tune it was rich as hell.

how much does the PSI rise with the boost only source? thats how mines hooked up.

just say on 20 turbo psi.

We like to set ours up 43.5psi with boost source only. That is if the injectors are sized correctly.

Fuel pressure will rise another 20psi. The average regulator is on a 1:1 ratio, so every PSI of boost will cause fuel pressure to increase 1 PSI.
