when must you use super gas, and race gas

Kamin

i was gonna post this in your other thread

why do you think you need race gas? its only need for very high compression motors or motors that run HIGH boost.

i just get 92/3 or whatever is at the pump.

running racegas if you dont have to is stupid and will probably hurt performance. more octane dosent mean more power.

, use 93 octane on your lsvtec with 12.3 -1 compression, its fine

but if my CR is over 13? then what?

your compression wont be over 13:1 unless you are using some crazy domed pistons. If you plan to use CTR pistons on your ls/vtec then you will be fine with 93 or 94 octane.

when do u get race gas from if thre track isCLOSED

If your compression is too high or you are using a lot of boost (increasing effective compression) then you must use higher octane fuel and more of it to prevent detonation.

wm5holla

how high?

Depends on the motor. People say that hondas can run higher compression than other motors due to the superior cooling ability of aluminum heads and their combustion chamber geometry. Also, injecting more fuel cools the mixture and prevents detonation. Most people feel that a wee bit over 11:1 is ok on high octane pump gas. The problem is when you get a little too high, you need to retard timing to prevent detonation. If you retard timing, you lose the HP you gained from uping compression. Most people seem to think that around 12:1 and race gas is in order.

Please note that I am being conservative when I give those ratios. I am also very conservative in what I chose to believe.
