Oh jezzus, i'm being bashed over the internet..... what ever shall i do.....

Yes "ambient" air runs through the IC and rad, then out the bottom of the car, i dunno about your supra, but my Supra still has a stock "air box" for a reason. The intake portion of the "box" is seperated from the engine bay by the chassis and runs into a space behind the fog light, seperated from the IC by a plastic panel. I believe he did answer his own question, he's searched over the internet and found a general HP limit on pump gas pertaining to his situation. Please, "mkiii boy", i'm 21 FYI. Had my Supra for 5 years now and I've had my Supe and friend's Supra's apart more than enough to know what i'm talking about, i slipped up and was caught by a troll, I only say this because a simple search of your posts reviels alot of bashing and critisism, even if the poeple were wrong, and not much helpful info adding to the site. Don't take this personal though because i've never met you in person to see who you really are.
