Max Boost

[turbo-sil40]

My question is am I able to run 20psi on this setup-
GT2876R
Equal length manifold
SAFC2
Greddy profec B spec 2
Venom 720cc injectors
bottom end freshly built
Full exhaust 3.5 in. to 4 in.
walbro 255 pump
nismo fpr
N60 MAF
Took it to the dyno to correct A/F the car ran 12.0 just about all the way to 7200 rpm on 7psi just for a break in and it made 190.35 hp and 166.79 torque. Run conditions were 77.64 degrees and humidity was 10%. Now i wanna punch it up, do I have enough to run 20psi or do I need something else.

why not go back to the dyno and start turning up the boost in increments and watch the a/f ratio's until you get to your desired boost level.

Just beware of the timing. As for fuel and AFRs, you seem to be pretty good.

How do i go about adjusting the timing should I use a timing light and turn the CAS until desired timing. Or should I pull one degree of time for every one pound of boost i run until I reach 20-21 pounds.

If you are asking this kind of question don't touch anything. Head directly to your tuner before up turn the boost up. You can only change the base timming. this is a set and forget affair. If you are not sure in what you are doing leave it well alone. Otherwise you may end up with a heap of broken engine and empty pockets.

Dee nailed it. You have all of the supporting mods EXCEPT the most important one! You have NO way to control timing. You need to at least get a chip burner and some software and become familiar with the stock ECU. Running 20psi on that setup will work for a while, but I think your lack of timing control is going to give you issues. You could throw extra fuel at it (run 11:1) to be safe but it's a bandaid.

How do i know how many degrees of timing im running now can I use a timing light bc I know turning the CAS controls how many degrees it is. The CAS is all the way advanced, so I want to set it back to stock then go from there. I want to see what the engine will do but I want it to be right

The CAS shouldn't be all the way to the right, something's not correct there.

Set the base timing to 14 deg BTDC.

I wouldn't run Venom injectors, unles they're a different brand to the one's I'm thinking about

You need something like an Apexi Power FC or Nistune to properly get your CA setup, messing around with an SAFC is just going to end in tears.
