do you guys see a problom with runnin 9.2-1 compression with iron heads with no intercooler, but meth injection on 93 pump gas and running it up to 15-20 psi??? kepp in mind this is mainly a street car. looking to make around 600whp with a paxton novi1200.... also with the novi1200 kit its comes with a box that encloses the whole carburator and pressurizes it, do i still need a blow thru carb??

oh yea, 410 inch smblock, forged assembaly, stage 3 ported x heads, hyd roller .575 lift, eddy victor intake, tti step headers.

You're basically doing the same thing as I am planning on doing. Mine is 9.3:1, non-IC, E85. I won't run as much boost as you, but you'll have no problems doing it.

Meth is good stuff, even better then E85. I know that the turbo guys just ABUSE their stuff on E85, so you should be fine.

No you don't need a blow through carb if you have a box. I just don't know how great the box really works. That's definately an old school approach.

this is what the paxton kis looks like with the enclosure for the carb

I think 15 may be 17 pounds at the most but you would want to watch for detination.
