I picked up 51 rwhp with the btr stage 3 truck cam in your 5.3

 

Do you have the chart on this? I'd love to see more of the low end torque.

Intresting, id like to see a graph next to it with say a tsp220 cam

 

And what did he say?

 

FYI...That graph was dyno end in second gear (stock driveshaft) trhough an FTI 3200 stall unlocked

 

Following up on an old thread but my LS3 swap with BTR stage III truck cam goes on the dyno today (finally). Will post up the results when finished.

 

Forgot to update with my results of the BTR Stg3 Truck cam in a LS2 GTO. It's a ported LS2 Intake, 243s with a good VJ and milled .030, Kooks 1 3/4" headers into 3" dual exhaust, UDP and ported TB with Vararam Intake. Made 432 SAE and 442 STD thru the A4. Look at the flat torque curve and it peaks higher then one would think.

 

wow! great numbers and a testament to BTR for designing these truck cams for heavy vehicle. I have my stg III stuffed in a stock LQ9 mated to a Yank 3000 stall and absolutely love it, curious what numbers it would put down though.

 

On three pulls to 6500 my truck made 370/372, 370/370, and 370/368. So it's certainly consistent. My guess was 380 and I was secretly hoping it would hit 400. Between the transfer case, 14-bolt, 4.10s and 22" wheels I'm sure I'm trying to overcome more drivetrain loss than most. Best part is the driveability with the converter is 100% better. Overall I'm happy and highly recommend Andrew and Complete Street Performance.
