this is unbelievable as it's almost 70 rwhp more than my 06a6 stk and almost 40rwhp more than I got with K&N CAI, headers and tune! What is this at the crank??People say the 08's can't be underrated so how do we explain such a huge difference in dyno numbers?

Because drivetrain losses are not a fixed "across the board" percentage, but more likely a fixed, or near fixed, number.

My Z06 and your manual C6 do not necessarily both lose the same percentage of power in the driveline.

I don't necessarily lose 15% of my 505. If I had 605 would I lose 15% of that too???? How about 705 or 805......905 still 15% no matter what?????

No, I think not.

This thought about manuals losing 15% and autos 20% in the driveline, across the board, no matter what, is :

They say the LS3 is a heavy breather and responds to mods like headers, CAI much better than the LS2

11.84 @ 121.4mph w/1.95 60'ft on runflats....with LG Headers, Vararam, tune & ported throttle body

Still waiting on Robert at Advanced Dyno(Vendor on this site) to send me the graphs, but like I said 11.7 A/F and power started to fall off around 6250rpms.

Why are we talking about LS2s in this thread?

Great numbers. They don't lie right?

Ignore the haters and don't even respond to the dumb comments.

Q: Have you changed out any of the lubricants from stock, motor oil, trans, or rear?

I just ordered 2 Q of the Amsoil severe duty 75W90 synthetic rear end oil w/ 4oz of the additive to ward off the rear end clunk. Figure it might help w/ power as well. Thoughts or experience?

Great numbers. Plus you'll pick up some more power once you lean that puppy out some.

Here is another LS3 dyno with the stock tune:


Looks like mine is identical, even leans out the same in the upper rpms. Interesting stuff.
