Renntech officially states 650 horsepower and 840 lb/ft of torque for an ECU reprogrammed SL 65 or CL 65, but dealers are dynoing these cars at well over 700 horsepower I've been told ......

Seems Renntech is being conservative in their estimates .....Just like how Benz claims their standard 600 V-12 engines produce only 493 horsepower but they're being dynoed stock at 580 to 600 .......

The tuners might already be hard at work on having internal upgrade packages for the 65 engines .... this should indeed take them to 800 or more horsepower ... but still don't know if the transmission will be able to handle it .... even though the 65 trans has been significantly strengthened over the standard 600 transmission. Atleast there are now Benz dealers out there with strong ties to Renntech and have dealer & Renntech backed full 4 year 50,000 mile warranties on all aftermarket work, so even if you have a 700 horsepower SL 65 and you keep blowing the transmission every couple of months, they'll just keep putting in a brand new one for you every time no charge.

Also, so far I have not seen ANY auto magazine really seriously gun out any CL 65 or SL 65, I mean really put it through the whole works, put them through the paces with measuring gear and get some solid numbers down. .... every article I've read so far just states official conservative factory numbers .... which everyone knows are extremely conservative in their estimation .....

I can't wait for Car & Driver to gun the s**t out of an SL 65, since the standard SL 600 is doing zero to 60 in 3.6 seconds already .... also I'd really like to see them post up their best 1/4 mile and zero to 100 and zero to 150 and zero to 200 times for the SL 65 .... I have a suspicious feeling that not only will the SL 65 absolutely destroy any previous SL 55 or SL 600 times ... but that the time might be competitive or better in some cases than many ultra super cars that cost well over $400,000 each.
It's already really getting fishy and weird that nobody has tested the 65's thoroughly .....

Any thoughts? Comments? I don't know how many people on this forum give a crap about Mercedes but I think there's atleast a couple others besides me that care ....
