Turbo efficiency and alky

[GDNF2ET]

My DSM runs 22 pounds of boost on 93 with no knock...My evo 16g turbo is efficient up to 22psi... Would alky benefit me even though I'm at my turbos peak on 93 ?

without a doubt probably 10 more psi plus higher timing. you havent begun to hit the efficiency of those turbos

You might get some more boost... The only map I have for the 16G shows it is still 74% efficient at 25 or so psi.....

What alky will let you do.... is run more boost than pump gas.... and if you are currently hitting 22 psi.... with tuning 25+ shouldn't be an issue.... and since the alky cools the intake charge off so much.... you can likely increase the timing to give you even more power......

BUT..................... BE WARNED............. Anytime you go beyond where you regularly have been... you are taking a chance at scattering the motor. May not have any issue.... but IMHO... you should be able to run at least 25 psi with more timing using pump gas and alky if you are currently tuned for 22 psi and no alky.... bigger hair drier.... might get you 30 psi on pump gas and alky....
