The guy in the other lane...quite interesting...

Wow.

It's so sick how fast these TT V12's are with just a tune.

I'm excited now that some tuners are finally throwing on upgraded turbo's and cranking up boost for race gas.

it looks scarily fast

What are the mods done on the engine ?

As far as I know, Renntech uses the stock intercoolers...

Why do companies like Speedriven engineer those big intercoolers if you can reach those speed records with the stock ones ?

Not really ECU only, sure it had lighter 18"-17" rear drag wheels + from article: SL65 were a RENNtech airbox, RENNtech tune and Hoosier drag radials. (although not listed I bet RENNtech upgraded IC pump was installed too??) Very plausible w/favorable DA & sub 1.6x 60' IMPRESSIVE AS HELL nonetheless! Congratz to ALL involved

PS Speedriven powered 65's run much faster including Traps in the 133-135 mph range vs this SL65 @ 128 mph.

DON'T confuse it w/SGC's CL65 it has 1-off true Ram air CAI, 1-off Ceramic super lightweight rotors, Carbon Fiber Driveshaft, light weight wheels, weight reduction, Intercooler pump upgrade kit, heat exchanger, more than likely @ 29-30 psi etc..

A little birdy told me that RENNtech IC pump is actually a BMW....ssshhhh don't tell anyone; top secret spy stuff

Who's car? Is this yours too, SGC?

Congrats, can't wait for my first 10sec pass. So close.....

Thanks DCMETRO22Z, it only has Renntech Airboxes and a Renntech tune.

Car has stock intercoolers, stock heat exchanger and stock pump. Heat soak is an issue.

Will lose 3-4 mph trap speed if don't let cool down.


Thanks Ricker. The SL is my personal car, and it still has the stock intercoolers, stock heat exchanger and the stock pump.

I was going to leave it stock; however, I have no self control when it comes to leaving cars alone. 11.50s @ 121 was not fast enough , so I threw on a set of Renntech airboxes that were collecting dust in my garage from my old S65, and had Renntech put a tune in it. Also, I ran 18 inch Hoosiers on Renntech Monolites. I've gone nearly 130 mph trap speed letting it cool down, and it slows down to 125 - 127 mph when it gets hot. It needs a better pump and heat exchanger. Probably the next thing I'll do.

With a ram air system, better intercoolers, more efficient heat exchanger, better intercooler pump, and 100 octane, it should run 10.4 - 10.5s @ 133 - 135. If take some weight out, like ceramic rotors and carbon drive shaft, should go 10.2 -10.3s @ 136- 137.

However, the best bang for my buck was a Renntch tune, and a set of airboxes from my garage

Thanks Benz-O-Rama. Its my car. Had it for awhile.

I was trying not to mess with it. No such luck.

SGC

Benz-O-Rama, you definitely have the mph to go 10s.

I just watched your 11.1 video, sounds like they're not afraid to use plenty of traction compound at MIR. I'd really like to make some passes there, as we are always fighting the heat and traction at PBIR.

Also, your SL600 sounds nasty (in a good way) compared to my SL65 - you can't even hear my car going down the track. I can hear your turbos spool through the exhaust on your burnout. Did you delete the resonators or cats? Sounds great.

Bring it up in the spring! You will love it and the people. I haven't been to a better track Congrats on the record

Btw, how much weight did you save with the cf driveshaft and where did you get it?

Benz-O-Rama

The 11.1 run is old news....I've gotten down to an 11.02

But yeah, MIR is prepped very well. I still had traction problems at our last rental though, but that was because of track temp. Not much could be done about that....

The only exhaust work I did, was a simple rear muffler delete. There are no resonators on these cars, just 1 pair of beer keg sized cats.

Congrats again, and bring it out to MIR!

SGC

Thanks BlackBenz.

Renntech had the shaft made.

I think it saved at least 10 - 15 lbs of rotating mass; however, the additional strength was what we were really looking for.

If my memory is correct, the ceramic rotors saved about 100 lbs of rotating mass.

Great videos and congrats on the 11.02.

3 hundreths of a second separating you from a 10.99. Thats a killer.

BTW, the SL sounds great with the rear mufflers out.

I'm rooting for you to get that 10 second run . Sooo close.

May plan a trip to MIR. Let you know.

blackbenzz

I see. Thanks for the info. I know renntech does all your work but I was wondering who they got it from. Rebranding and charging a crazy premium is not my cup of tea

Sweet freaking thread. I love Mercedes power. It is amazing what little respect we get. I have had many a midnight run (in Mexico) with people that say "are you serious, we are running against an F-ing Mercedes?" I smoke them with my modded 55k. I could only imagine what they would say if a nicely modded V12 ran their ****!
