After looking through some of his pics, the tread looks like the BFG DR. What amazes me the most is the fact that he is running as fast as the Renntech SL's even though they have an LSD and he doesn't.

Where did you get the mods done? What was your rwhp before the mods? On the dyno with 610rwhp is that on 91 or 100 octane?

Roger got his mods done at Renntech and his S65 has Renntech Stage 2. He was using 100 octane.

To answer a few questions:
The only mods on the car are the renntech ECU and Airbox.
I installed both of them in my garage at home.

They were BF Good Rich Drag Radials 275/35/18

The 610RWHP was on 100 octane.
The 11.0 pass was on 100 octane.
It runs consistent 11.4s on 91 octane.

Here is the Dyno before the Renntech Mods:

Perhaps becuase the S65 is so heavy it just hooks and doesn't spin? How much heavier is the S vs. SL's?

WOW, Benz really under rated that car...as someone said earlier probably to position the SLR as the top HP dog.

Thats 10% drive train loss. Its really a stock crank 675hp/810tq car...amazing.
