Disclaimer:
The following info is a little messy because I've dynoed on 3 different dynos in varying forms of trims (street and race).
My best previous dynos were running the Thunder Racing TRak cam (233/235 .644/.598 112LSA). On a nice crisp October morning, I got an exceptionally good dyno (SAE corrected) from Racing Solutions that was 472 rwhp/420 rwtq. When I dropped the catted y-pipe and ran open headers, I gained 6 rwhp/8 rwtq. Dropping the belt gained me another 9-10 rwhp.
Before the RSI dyno, I put down 455/402 on Thunder's dyno (through catted y-pipe and 85mm MAF) and later in Feb '06 I put down 466 rwhp/410 rwtq with open headers and no MAF on Thunder's dyno. Had I run my catted y-pipe, the numbers would have dropped to 460 rwhp/402 rwtq.
In March, I swapped to a Comp XER 234/238 114LSA cam as an experiment and returned back to the RSI dyno. Through the catted y-pipe, the numbers were 458 rwhp/400 rwtq. Sadly, I could not duplicate the stellar numbers from October. Was it an exceptionally good correction number that day? Who knows.
To average things up as best we can, let's throw out the October dyno and look at the dyno numbers that seemed to be repeatable:
Typical numbers for the 233/235 .644/.598 112LSA +2 cam through catted y-pipe in pure street trim were around 461/402 rwhp
For the XE-R 234/238 .598/605 114LSA +2 cam through catted y-pipe in pure street trim were around 458 rwhp/400 rwtq
Today, I went to MTI and dynoed my new Thunder Racing Torque Series 224/228 .637/.639 110LSA +0 cam through a catted y-pipe in pure street form and put down 459/410 rwtq.
Here's how the numbers compare between the cams (averaged):
.......TRak cam..XE-R cam..Torque Cam (rwhp/rwtq)
2500...130/290..128/270...150/320
3000...191/335..183/320...200/350
3500...247/370..233/350...247/370

4800...367/402..366/400...375/410
