im running a b16 with ctr internals. what is the best octane to run to get the most power out of it???

is 110 octane too high??? i heard that high octane sometime make the motor run more slugish, so let me know whats up.

 

high enough that it does'nt knock, which 91-92 octane should handle just fine...............John

 

would 110 octane make my motor faster or would 91-92 octane??

what is the hype about higher octane????

You want the lowest octane you can possibly get away with.

High octane burns slowly and doesn't atomize well, you're likely to lose power or do engine damage with racegas unless your engine is downright nasty and can't run on pump.

 

I use 93 in my 12.3 CR LSVTEC

But I would like some clarification on why race gas would cause damage to your engine, it just does'nt seem logical at all to me. I can understand it losing power but not causing damage..........John

Burns slow, you run stock ignition timing which doesn't ignite the c16 early enough to get anything aaproaching a thorough burn, and you end up with still burning fuel-air coming out your ports when the exhaust valves open - just like having your timing too retarded. If that doesn't overheat the combustion chamber and shitcan your engine, I dunno what will.
