First Track Run
Hi Guy’s,
Well after three years of driving my SL65 I final got it on the track. I guess it not as easy as it look to get it going down the track and all runs was done with tracking control on. This is the fast time I could get after 5 passes on the track. Man, it was a lot of FUN..

Your driving is good but your car is down on power. A lot. You should trap over 115. You essentially fell on your face after he 1/8. Check your intercooler pump it you have not done so already.

I agree. A 108 is a slow trap for a 12.28. Even your 1/8 and 1000' mph is slow. Here's my slip from my best run in an SL55 for comparison. Your times for each segment...60',330, 1/8 etc...are close to mine, but your mph is way off at each point. Maybe its the Traction Control? Try lowering your rear psi to around 20 and turning your TC off.

I've never run with the TC on so I don't know exactly its effect, but I know from it being on on the street it feels like its intermittently cutting power to the wheels, and thats why I threw out the TC idea.

1.8 sixty footer, low 12s and you gained only 8 miles between the 1/8 and 1/4 mile?

So your MPH is good all the through the run, but your 60' is .45 slower and the over all run is .14 slower (that 2nd slip is a 12.42, right?). That means that the slower run was A LOT quicker beyond 60'. A little more than 3/10 quicker. And the trap speed bears that out.
Im no expert and I could be wrong, but I think that its your TC that is holding you back a bit. Next time try turning it off and compensate by lowering the psi in your rear tires to 20-22 lbs. Everyone is different and mine is a completely different car, but this is and coming out at 1000rpm is what works best for me. Play with it and find what works best for you. If you can nail a 1.8 60' and finish the run like you did with the second slip posted, you're flirting with 11's.
And btw, this wasn't your first rodeo was it? Your R/T's are a dead give away. Average Joe who takes his car to the strip on a whim doesn't consistently cut lights like that.

The trap is high because he spun.
That second time slip looks right for an sl65.
And yes- I too was about to comment that if you are cutting 1.8 on a street tires in the sl65 you either have a sticky track or you can drive well or... Both

You cut consistent 1.8 sixty footer in a stock undertired 600hp 4000 pounds car and you have never been at the track before?
You are a natural. Be proud.
Btw, shifting early has its advantages in the sl, but you want to hold second gear as long as you can as gearing is tall in the sl65 and as gears climb the car falls on its face at high speed. That is the reason why the new sl65 will be a high speed monster- 7 dense gears.
