Anyone have an idea of how much boost I can run on 94 octane pump gas?
I have a Walbro FP, Adj. reg., 3"THDP, 37# injectors w/chip, 2.5" exhaust.
I never messed with the boost but I do have an adjustable wastegate.
Will I blow it up? I have no knock now. Should I let well enough alone?
Also, how much FP should I give it?
No, I dont have a scantool....Yet.
Car runs great, I want to keep it reliable.

Thanks!
 
Do you have a knock sensor?
Or it is that you can't "hear" it knock?
Without a tuning aid (scantool, or at least a knock gauge) I wouldnt touch it if I were you.
Some cars run differently, some will take more boost than others, but you really cant safely tell without some sort of feedback. Even if you do have a knock gauge, I would hope that a scanmaster or other tool will be in your near future.
On 94, I would stay under 16lbs if I were in that situation.
 
Assuming you have a stock turbo, you can run 15-17lbs of boost. But I still wouldn't do it until you get a scan tool.
