[QUOTE="Kevin @ Wicked, post: 7713866, member: 18076"] I know well enough on intercooling, forced induction isnt new to me. I made a comment to the customer when he was buying this kit because i saw the setup on a previous car we had to piece back together and i ask if he could get the kit minus the cooler and pipes because i would have like to fab up our own stuff and use our own core. Made another blast today before customer picks up and a 3rd gear romp to 5500 is yeilding a 40* above ambient increase. We were about 50* before the hit, and by 5500 and 14psi, at 90. If we continued the pull to 6500 like we intend to spin this combo to (didnt because we are still on break in) im sure it will be higher than 90. Im just concerned with a 1st thru 4th pull as the heat gets compounded and the core starts to heatsoak. Im taking LOADS of data from all the centri cars we do and high boost applications and comparing it to this and so far we arent impressed. Thats all. This isnt a thread to say it doesnt make power etc, the car feels unreal at only 14psi and 5500 rpm, i can only imagine what its gonna be like at 6800ish. But the IAT's will have to have a watchful eye. Dave Im familiar with the lightning iat, used to use em on the 2v centri's when we were still draw thru, we opted for the IAT built into the HPX sensor, its right at the TB, so its reading a fairly accurate indication of air entering the motor once the intake is flushed out and cooled by the incoming charge. If we were using the metal lightning sensor and had it drilled and tapped right in the intake i would suspect higher readings than what we are seeing. Just like the 5.0's and eec-4's we always move the threaded one outta the intake runner and into the charge pipe just prior to the TB to get a more accurate reading of air prior to heatsoak from intake.
