hey guys. I am looking into my next project before I have already finished my current one.

my next project I am looking at building a 2wd turbo ls swapped 88-98 pick up.

where my question lies is. in Ontario we don't have e85 or to many gas stations that have fuel over 91 octane there are a few but not many.
how much boost could be run on a turbo cammed 4.8 or 6.0l while running 91 octane with out meth safely? would it be possible to push 600 wheel hp?

thanks

That should be an attainable goal I dont see why not. Just have a good intercooler, a 4" would be best if you can fit it. I mean why do you have to have 600 hp right off the bat? Get the truck all setup and tuned good on lower boost and then turn it up and see what happens, if bad things happen save your $$ for meth. Thats what im gonna have to do, I cant go past 12 psi right now or else my IATs get too high

 

thank I will start low and turn it up as the time goes. I just don't want to buy something and its not capable of producing those numbers then have to swap it all out if you could just buy the stuff to produce those numbers the first time. any one else have any input on the 91 octane fuel?
