I have an all forged ls1 that I was going to spray with 300-350 shot of nitrous. I am now thinking about going to a blow through carb set up. Anyone running compression as high as I am? Talk to me about what to look for, what to change, as in cam specs, turbo size waste gate's blow off valves, carb size, ect. The motor made 443rwhp.I would like to be around 800rwhp on boost.

This will be going in a second gen camaro drag car should be 3000lbs

Switch to E85 and LET IT EAT!!!!

 

Yep, ditto. I don't know what your cam specs are, but at that compression I would contact someone familiar with turbo setups and higher compression. They can do a lot in the way of dynamic compression, your static compression doesn't really mean anything. Change the cam, throw in some e85 and let her rip. That is my next setup, a high compression turbo motor. That setup should make you very happy.

 

As stated
Cam plays a big part
E85 if available

Regardless of route you go the compression won't stop you it will just make it more critical that your tune is on and fuel up to the task.
