Off to the dyno...

I'm back.

I have made no changes to my car since the last track outing where I ran mid 11's @ 123.xx mph. I made a baseline pull and about crapped when I saw 350.9 rwhp @ 5500 rpm and 341.5 ft-lbs @ 5250.
The car was very lean, and had inaudible detonation. This was with 93 octane gas. We richened it up, and ended up getting 365 rwhp. I then tried a pull without my homemade 3" pvc cold air inlet that grabbed air from the foglight hole, and put the meter and filter where Paxton intended.

Next pull, 393 rwhp @ 6000 rpm, and 365 ft lbs! It not only made more peak hp, but under the curve was up through the whole run. I could not believe I picked up almost 30 rwhp by tossing my "good idea".

I made 8 psi consistently, with no belt slippage. Now the car is chip tuned, and feels night and day on the street. It actually feels wicked fast.

I had the tuning done at Detroit Speedworks, in Warren, Mi. www.detroitspeedworks.com. The owner Greg is a member of this site. (Turbolx)
For kicks i'll probably make a Dynojet pull when the weather cools off. 90 degrees and humid is not good air for a blower car. I am not sure what it will do, but on motor I dynoed 270 rwhp on the Mustang Dyno, while netting 309 rwhp on a Dynojet. About a 40 hp difference.

Now to put the bottle back in...
