ok so im going to the track tomororw and im woundering what I can turn my boost up to for only a few runs. Right now ive got a Dynoflash ECu and run 20.5 PSI but im woundering if I put race gas in if I can crank it up a few PSI and still be safe.. what you think???

 

On a 50/50 mixture of shell 93 octane and c16 116 octane, I run anywhere from 27 to 32 psi... usually around 28 or 29. However, I am tuned for it and have many supporting mods to do so... but keep in mind, it'll always taper down to around 21~22psi at redline.

 

yea im not gonna turn it up anywhere near that high cause im still running stock Injecotrs. I was thinking maybe like 23 though but i know its gonna run a little lean on top cause im not tuned for it but is it still safe for a few runs?? Right now im tuned for about 20.5 PSI

 

20.5 is a great number, dont go above 24psi for sure, but honestly you may see better results at 20.5 to 21 tops, good luck!! The car prob will pull timing bad up top.

 

I'm running on stock injectors as well... and I'm spiking to 28psi easily... but yea, definitely don't recommend high boosting without other supporting mods (fuel pump, headstuds, etc.)... and without effecient tuning.
