Modified SL55 vs stock SL65 who would win ???
Anyone have any experience with a Renntech Modified SL55 the package they sell for $15k that gives the 55 613 hp and 626 trq? Does it make the 55 capable of beating a stock SL65 ??

I spoke with one of the guys from RennTech a while back when I had my 55, and he said that they will be about even until 80 mph, and that's when the Turbo's of the 65 will kick in, and the race would be over for the 55 shortly after!

The 55 has better top end? Why?
I second the comment that the 65 reaches 155 quicker than any other stock car I have driven. The mid range of this car is INSANE.

I've raced a Kleemann stage 3 (580 bhp) SL55 in my CL65 from 70 until 160 mph and at no stage could he gain any ground. From 100mph onwards I pulled the gap bigger and bigger until the 160 limiter, and then he caught me up and overtook me, as his car had a 187mph limiter, d'oh !

My apology, I didn't realize we were talking about limiters on the cars. Sure, if your SL65 has its 155 limiter on it, then any other AMG with its limiter moved up to 186 is faster.
If they both have their limiter raised to 186 then the SL65 will reach that limit quite a bit faster than a SL55 and a Renntech tuned SL55, how is that.
My bad.

supercharging a car is kinda like increasing its displacement, the behavior of the engine is the same, except more low end torque than a n/a engine, it pulls to redline, turbo cars run out of puff before they hit the redline, again im not sure why
the midrange is deadly though

Where are you getting your info from? I have spoken to people that have owned both and all say the 600 walks away at high speeds and the 65 is on another level.

Maybe the statement was referring to the point where the 65 turbo's become toooo dominate for the 55.

Hey Jeff,
Looking forward to some fun runs in the am. I have only a E55 with K2 so we can get a good idea when you start pulling on me. My guess from my last track day is that we will run close to the same 1/4 and trap but you would start pulling away with the increased HP&TQ over 120 mark.
If we ran a 1/2 mile run you would see the power of the 65.

Another issue is the heat produced by the V12s. AMG will not provide the AMG Sport package for the SL65 because the engine produces more heat than it can shed at high speeds, hence they will not raise the speed limiter like they do on the SL55.

Where did that information come from?
That is not correct at all. I know three people in Germany that have SL65's that all had the speed limiter raised at AMG in Affalterbach. It is common practice in Germany to take in your SL65 and CL65 to AMG to have it raised.
None of them have had any problems at all running high speeds for long periods other than the need for frequent fuel stops
True the SL65 runs hot in general but it is within specs. Take a look under the SL65 hood and you will quickly see why. That engine is stuffed under that hood!

At high speeds the temperature is fine, its only at lower speeds like in traffic the temp goes up a bit more.

The only thing they dont have which the '55PP has is the increased limiter, but in Europe you order this seperatly anyway.

With al genuinely due respect, does this Rob Allan person knows his AMGs? This is the 3rd questionable alleged statement from him I read here in a weeks time. About the SLR nose on the SL (which seems like speculation at this point), about the 6.2l 63 engine in the new S-Class AMG (which is being denied all over the place) and now this.
Mind you I'm not bashing or anything, just an honest question.
