How much psi with 16g on pump gas?

[13secGST]

Ok..I searched (once ) but I didn't find what I was looking for and got a whole bunch of matches.

My question is how much psi will I be able to run with a big16g

My mods now: 1gBOV, MBC, 3" Tanabe RM, 2.5" test pipe, K&N FIPK, AFC, EGT/Boost/Intake Temp guages, Upper IC pipe.
mods I'll have when I get turbo: walbro 255, big greddy 24r FMIC

What would be a safe boost level...what would be the max?
How much could I run when I get Denso 550's? What about 660's would they be better, could I run more boost with them?

Again this is all on shitty CA pump gas which is 91 octane...but I use chevron I'm sure the techron would let me run 10psi more right :laugh:

I would just keep it around 18.5psi on pump gas and with race fuel I would run it with 20+psi. I see nothing wrong with that.
My 20g I keep my boost at 20 for pump gas 28 with 110.

anyone else?

20gst's estimate seems accurate

 

[13secGST]

so even if I have 660's and the 255, if I have 91oct then I shouldn't go above 19psi?

what is all I have is the 255 is it the same 19psi?

also about what kind of whp would that setup push at 19psi?

your EGT gauge can tell you also
