turbo with high compression rotors
How much boost could I put on my engine (reliably) when it has high compression rotors(9.4-1)? This is a streetported 13b 4 port. Im currently running a weber 48mm sidedraft carb. Also, can I boost through this carb or should I go with something else? Thanks for all the help. Just want to go faster.

I have the same rotors in my TII setup.
I was not able to run more than 12 psi without water injection.
Actually, it started pinging at 12 psi so 10 lbs. is about it safely with a small room for error.
That was only on 91 octane as that is all we can get out here (readily) in CA.
Do a search, this has been covered extensively, even a few threads from the last few days about the same topic.
It is better to go with fuel injection instead of a carb with a turbo.
I imagine you could boost through that carb but I am no expert when it comes to webers.
If you want to talk about carbs on bb chevys, then I can talk all day.
