I run 21 lbs boost w/ 93 octane, what would be a safe boost level with 100 octane?

 

i run 25psi on 101 octane only. my '03 uses no other gas. this is how Al dynoflashed the car to gain maximum use of the stock turbo.

 

thanks, maybe i should dump a tank of 100 octane in my car when Al is in my area again, just to be on the safe side, so he can tune it and find max boost.

 

as long as you have a FULL 3" tbe, fuel pump, boost controller, & gauge, he can flash you for 100 but then you will have to use that octane ALL the time. if you have a shop in your area that does Ecutek flashes, that may work better for you cuz then you can run 2 fuel maps.

 

You run nothing but 100 octane? That must get expensive.

 

I run 26 psi on 100 octane and 29 psi on 105 octane

 

As much boost as minimal knock will permit. Get it tuned so you will know....

 

thats what its looking like. I was just wondering if there was a "magic" equasion to figure out octane to boost level, but looks like every engine is different.

 

Bingo!!! Even every Evo engine is different...

 

Beg, barrow, or steal a logger. Log your runs and watch the timing advance. Keep turning up the boost till you see flat spots or pulled timing. Turn it down 2psi. after that and have fun.

 

Swear to god, I have an RNR gt-35r and a bad boost controller. NO KNOCK at 30 psi on VP-100. I have data loged this several times. I am running factory timing on my UTEC. Its so fast, i could care less what the timing is.......might take the wing off next week. Afraid ime going to lift off.. Dont believe me??? come to my house......
