How much of a gain?

Hey guys I'm new to the board but have loved GN's for a long time now. My father has also been a Buick fan since the 60's. Well, I was wondering. How much do you all gain from the Alcohol injection? I have read a lot on Water/Alcohol injection and I see that you all seem to have experience with it so I figured you all here would have a good estimate to the gains. Thanks

You don't gain power directly from alcohol injection. But, among other things, it raises the octane level and allows us to run more boost, which does add power. For an estimate, many people say 16-17psi is the max you can run on pump gas (93 octane), but with alcohol injection most are running 23-24psi.

Oh I understand now. It allows you run more boost with safety and that intern produces more power. Thanks
