I would be more worried if you have the engine to back up the intake. The Box is like all others and it is a flat power band till about 3200rpm and it did not show any gain in torque till about 6600 rpm and we shut the car down and was 40hp less than the RPMII all across the rpm running 14psi of boost.
i have a 12.5:1 comp. 347, with fully ported canfield heads, 600" hydrolic roller from bullit, 1 7/8 kooks headers, 75mm TB, 80mm mass, and power pipe, and 200 shot of nitrous, i think that this in take will work well but maybe not, what do u think
