Default Bolt on dyno #s


new to the fourn but figured I’d post dyno #s. 2005 c6 base m6. Car has 120k. Mods are slp CAI. Fast 102. Ebay headers(they actually fit 150$) connected to the stock x pipe back to an slp loudmouth.

Dynos are tuning tools that have their greatest value in seeing the difference between the first pull and the best subsequent pull after tuning changes.
Dragstrip timeslips are also tools to tune not only the engine, but the car and driver. They are the better indicator of real power and driver control. Here are examples of dyno sheets vs timeslips.

It's not meant to diminish the value of your dyno results, but just to show the differences between the tools and methods.

It made I think 405 the first pull but the tuner said it was way lean. They even said they were suprised because they usually only see them make around 390. I am nervous to track it because I don’t know what shape the rear diff is in it.

LS2's have a crummy intake and intake manifold, with the headers CAI, and especially the 102 those numbers don't surprise me for a M6 congrats!! I'd like to see 390hp from my 07 with vararam, home ported stock intake, zo6 manifolds and mid pipe and tune.

I understand the concerns with the '05 diffs. Search for posts by Joe G. He's very helpful re: '05's.

Maybe I didn’t do it right. But searching 2005 differential with “joe g” had no results.

Try "Joe_G diff" without the quotes. About 170 results.

https://www.ebay.com/itm/201772036484 . Had to massage them to better clear the frame. Had the exhaust shop hook it up to the factory x pipe for $75.
