TSP 402 Texas Giant #'s
Hey guys, I finally got the bugs worked out and made it to the dyno today. The numbers aren't great but considering I have small headers, PRC heads and my Fast intake isn't ported I am pretty pleased. The motor only has 250 miles on it so its still pretty tight and it was probably 90+ degrees in the shop when it was on the dyno. The rest of my setup is in my sig.
Numbers
463rwhp/426rwtq closed cutout
497rwhp/448rwtq open cutout Yes that is a 34rwhp gain with the cutout
This is proof of how restrictive Flowmaster's are

one of my buddies just got a 402 ls2 in his TA..he said it put down 480rwtq but he didn't tell me the horsepower it put down..this was also with 1 3/4 inch headers and he is now switching to 1 7/8 headers so the numbers should definately go up ...oh yeah he also took it to the track and let off at the 1/8th and still ran a 12.3 so that thing flys...i wish i could afford one but anyway nice car and with some other little tweaks it should put down some great power
