Holykrap! this is great Jay! #'s please!! what Octane tune are you runin'? Side Q: Are those IC's bigger than VRP kit? or same? looks great!!! can't wait to see your 1/4 mile & Dyno results..
Did you leave TCU alone or?

My TCU was tuned by AMG a while ago when they did the ECU tune. I am running the same 93 octane tune. I never put huge stock in dyno numbers as they only tell part of the story, I put more emphasis on trap speeds. This is the VRP Intercooler and Intake setup with my same tune. I made 541rwhp pre-dyno and 548rwhp after the parts were installed. But this doesnt tell the whole story as those are only peak numbers, I made 25rwhp under the curve. Both dynos were done in 4th gear. I then added ice to the reservoir and iced down the cores and pulled 562rwhp. I am going to the track on Friday and hope to better my 10.98 which was done in 55 degree weather. It should be around 75 degrees+ on Friday, If i can do a bit better then the 10.98 in 20 degree hotter temps I will be content.

Why no rwto reading? I agree your trap speed will tell the rest of story IE 128-130+ mph hopefully
Edit: I remember your ecu/tcu was custom just wondered if you had vrp custom tcu or ecu to work in harmony w/kit figured it would be nes to get A/F ratio corrected & max HP/TQ after bolt-ons

Interesting, I bet the CAI is responsible for majority of rwhp gains, the stock boxes have (3) 90 degree bends = krap intake, + another member has custom 1 off similar CAI made 30rwhp on SL65.. I'm more interested in RWTO gains?? Marko stated he picked up near 150+ rwto w/just bigger IC's

The increase in power(HP and TQ) that I noticed on my 65 was from the lifting of the restriction of the stock intercoolers. My boost went from 22psi to 25psi. Jay is still on 22psi due to software. The stock intercoolers appear to not want to flow well above 21 psi. Once his software is modified to not limit boost, he will see more gains. I'm not sure if the gains will be as much as the 65, but should be close.

Getting a tach lead to get RPM is a major biatch on our platform. That being said you can get a rough estimate by looking at your speed and extrapolating RPM from that speed and doing the math. Tom usually does it for me. I stopped focusing on TQ as it peaks so early in our cars and in a typical 1/4 run its only usable in 1st gear, after that that huge spike is gone. "TQ gets you moving and HP brings you home" Thats why our cars are relatively weak in a roll-on race as soon as you mash the pedal the car down shifts are youre at 4k+ RPM well beyond that monster TQ number. Think about a typical 1/4 mile run, after you launch in first gear and your car shifts, it never falls below 4500 RPM, well outside of that biq TQ number.

Jay! I knew our cars weren't dogs during roll-ons
When on Freeway cruising the 600tt before roll-on scenario @ 60 mph = 1800-1900 rpm's @ 70-75 mph the rpm's @ 2000, upon flooring it (did this today, roll-on style for giggles) it downshifts & rpm's shoot to 3000 rpm's @ 80mph, then @ 85 there @ the height/peak of the Torque band 3500 rpm's, that launches my SL600 ahead like crazy, then it starts to decline on torque band & HP takes over up until peak HP @ 5000 rpm's. Sheer monster on frwy rolls (that's where 90% of all my racing takes place) I think you're comparing perf too closely to 1/4 digs, unless your roll-ons start @ 85-90 mph

Interesting that it makes less than the 65, although the 65 does have bigger turbos to feed, so it has more to gain, plus its a bigger engine. I am loving those wheels, anybody who puts Volks on a big Benz is the man, imo. They look like TE37s, are they? I didn't know they made those in the right bolt pattern?
