Definitely a cool dude) for some friendly comparison runs. As those who've been keeping up with the news around here, now my SL600s been getting it's *** kicked left and right and we decided to see if indeed there is something wrong with my car by lining up.

And the results, yes. Very much so in fact, every run we did he pulled multiple car lengths, averaging bus-lengths on the freeway. Embarrassingly enough, after one run, he even asked me if I left off-- NO, you jackass I've already taken my car to the shop and they've found the problems (IC Pump, collapsed transmission mounts) and I am in the process of fixing them. Today's result solidify what I've already known-- my car needs (warranty) work!

Anyways, all that out the way we managed to strap his car to a DynoJet at HK Motorsports in Oxnard; which I hear is rumored to be quite a conservative dyno. His SL600 was strapped down and had 3 ridiculous runs:





And here's a video.

First run, his car mustered a whopping 480WHP! We thought that was amazing, so after a classroom session (LOL!) we went back for round two. I was expecting the WHP to drop due to the extreme heat in that shop (last I recall, it was near 90 degrees!) but no... his second run ran an even more impressive 490WHP. And his last run... well... he ran his best, a breathe-taking 501WHP!

I do not have the DynoJet charts, but Sean (TheRicker) will post them as soon as he chimes in here.

For comparison, there was a E63 with headers over there that ran something like 405-410WHP. Also a C63 in the mid-300s, Sean correct me if I'm wrong.

All said and done, I was impressed and can't wait to get my 600 fixed to join the party!

And Sean, here's just a pic of your car from the freeway runs:



And another (1)video.

1/2 tank 91 ****-octane mixed w/latest Torco octane booster = about 94-95 Octane. Got their an hour early popped hood iced-down both IC's then strapped her down (Only had about 15 miles on Octane booster so I think she adapted as we dyno'd, about 15-20 min bet pulls) 95+ degrees in shop

1st pull 487.21 RWHP
2nd pull 489.05 RWHP

3rd pull 501.72 RWHP


Thank you for the informative Dyno session Harry (Owners name is also Harry)

(No RWTO readings were taken) All runs were done in 4th gear.

They also had previously dyno'd (In the past, & showed both Harry & I their charts) (3) C63's (1) CLK63 BS (1) E63 w/Longtubes, the stock C63's made 360 RWHP the CLK63 BS made 400 RWHP & the E63 w/Longtubes 415-420... So as you can see this Dynojet is conservative...

Before you guys cry foul, I had her dyno'd 3 weeks ago on Superflow Dyno @ Bottle Blown Racing (from experts here & research I've done Superflow compares nearly exactly to Mustang or properly set Dynodynamics "Heart Breaker" (SL had same fuel mixture) Completely Heat Soaked 45min in traffic then ran @ 100mph for about 5 min to make appt, ZERO cool down or iced went directly on Superflow. She made consistant 444 RWHP on multi pulls @ that time.


Very nice meeting you finally, good times bud
