G8 GXP - 490 RWHP N/A - Video Inside

![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
We recently installed our L92 Stage 2R MAX camshaft in a customer’s 2009 G8 GXP (6-speed manual). We’re very happy with the results. The car was baselined stock and made 351 RWHP / 360 RWTQ. When finished, it made 490 RWHP / 442 RWTQ…. A gain of 139 RWHP / 82 RWTQ! We haven’t had a chance to do any fine tuning on the street yet due to the current weather conditions, but I’m confident it will drive very good for having a camshaft this large.

I have a video of that cam in our GXP, but I don't have any videos of a GT with that cam. I know a guy on the G8 board installed the 1C and AR 1 7/8 Headers and exhaust system in his GT and made 400 RWHP.
