What is the stock boost for a 85 Regal T-Type. I have this motor in my 85 Chevy S-10 and need to know the stock boost. Thanx for the help.
12# max with the original non-adjustable actuator...some have seen as low as 8# stock...Anywhere between those two...this is with the factory chip...
Stock Boost

My car came with 8psi of boost when I got it, and it was in 100% stock form!

With that 8psi of boost under boost it would get up to the "Yellow" on my caspers knock gauge! Crappy Stock Fuel system!
