turbo basics

[grey1]

At what point would my turbo be the most efficient? As far as h.p. gain? Also, does 1 deg. of kr really kill my run? Thanks, Dave
(Now I can run 24lbs. w/ no knock, pump gas.) 25-26lbs. 1-2 deg.
At these boost levels will I be more safe to stay at 24lbs?

How are you running that much boost with only 1-2 kr, you must have alky.. right? TA-49 sweet spot is 22-24 psi.
1 or 2 degrees of kr wont kill ya unless you are running at those boost levels 25-26 .. I would stay away from that, but thats me.

What kind of pump gas is that, that allows you to run 24 PSI with no knock?

Mostly the Holiday 93. I have tried the Standard 92, but, could get 22lbs. w/ a 2-3 deg. knock at 1-2 shift. After 3rd gear, none. (22lbs) Using S-L-X from Home Depot without any mixing. Very Happy. Just wondering about retarding too much timing. Is 1 deg. on T.L. effecting engines perf.? If so, how much am I losing?(ballpark) Thanks, Dave
