Car just got dyno
Hi folks,
Finally got my car re-tuned and re-dyno after the upgrades. I upgraded with test pipe along with DC headers. final numbers are 354 and 219 tq and thats was at 11lbs of boost!! thats an improvement over my last dyno which was at 334 and 215 tq. But some how my boost have gone down quite a bit (??) throughout the rmp range, don't know why. I retighten the belt during the dyno because the tuner noticed a decreased in boost. I want to know is it normal? and now am boosting more. and my redline is also raised to 8900rpm. How do I post the dyno graph on this forums, so I can get some opinions on my dyno sheet! any help would be appreciated!!

Hows you "raise" the factory redline of 9000 by -100 ?
Im guessing my math sucks.

The Comptech blower can make 20+ psi, but it becomes quite inefficient after 55k rpm(its blower speed). IIRC, that is a 3.19" pulley at 9200 rpm(engine speed). Also, there is not enough data to presume that the tp, header, and retune couldn't yield such a gain. One day may have been muggy; the other not so much, etc.
NO S8NT put down 417 rwhp in a similiar timeframe on the same dyno with the same tuner as I did. I got 395 w/ my CTSC w/ AC and the car was seriously suffering heatsoak(not much later the Cometic head gasket failed
). Kevin's motor is completely built and resting at 9:1 compression, while mine is a stock block, Laskey head, and (was)2mm Cometic hg.He had single exhaust and 3" all the way back. I have a testpipe and Invidia. So yes, for soup'd up SC applications, go Vortech. Stock sc'er kits, I'd do CT again.
