Had Chris and Hoyt at Dyno Edge install a smaller pulley on my CTS-V. With a mail order tune this is what we got. First run is stock, last is with the pulley and tune, no other changes.


I'm pleased. :headbang:

Nice numbers out of a nice car! Got any pics?

There is an older gentleman here in Las Cruces with a new V with an STS twin turbo kit compounding the factory supercharger. The car is sex on wheels and sounds amazing! He said it laid down 700 horses with a mild tune.

Nice numbers! Is 445rwhp average for stock? I know they rate them at 550hp I believe. I know the z's dyno stock right about 445rwhp also, with a 505hp rating. Unless your numbers are uncorrected.

That's a pretty average number for a SAE auto tranny CTS-V. I've seen them throw down 430 heatsoaked, and up to 460, but 440-445 SAE RWHP is average.

In truth, they tend to run better than the dyno rwhp numbers would have you believe. Mine dyno'd 371 rwhp uncorrected stock but ran a 12.7 @ 112 on a 7,100' DA day. If you run the HP/weight calculators for 4400 pounds including driver, it shouldn't go that fast. Adding 70+ rwhp to that, she should be a solid 12.0 car here now. :eek:ldman:

Did not realize it was an auto. Bone stock auto on street tires [email protected] up here and 4400 pounds. That is kick ass!!

To be honest I don't know his name. I've talked to him a few times but never got his name. The car is silver. I'll be sure to get his name and maybe some pics next time I run into him.

6speeder, 12.0 in Alb, that is just nasty from that car. I love the small cowl on the hood of the V.
