2006 CTS-V on dyno

This is my 2006 CTS-V on the dyno for the first time. Numbers were not accurate due to being very hot out and using a very small fan. Adding that it's a portable dyno too. Numbers recorder were 331rwhp with cutouts open, xpipe, and no muffler.

Nice numbers! Thanks man. And yeah, I'm finally able to throw headers on her. There's a very trustworthy machine shop around me that can make custom stainless headers for me. He does custom exhaust work on lambos, Ferrari, Maserati, and Aston Martins. Shown me pics. Nice work. So gonna let him make me almost identical to the stainless works headers and install. Then finally tune. 400 rwhp is on the horizon!

Get some headers on that bad boy with a cat delete. I'm on 1 3/4 pacesetters with offroad pipes (no cats) on stock exhaust with cutouts... 371rwhp on one of the stingiest mustang dynos on the east coast. LOL Tune Time. I'm still on stock airbox. Nice V, chief.

Because it was 90 degrees out, it was a small indoor fan they had. And they even told me it wouldn't be 100% accurate.

What mkes you think a portable is not accurate?
