I put a fresh coat of Swissvax Saphir on this morning so I decided to take some pics of my ride.

 

dude those intakes are huge lolz.

Andy

 

Duuuude!! You didn't tell me you got the VRP upgrade!! So how does your car feel compared to before? Car looks fantastic by the way. Congratulations.

Larry

 

Big Lar...VRP? What? Huh? Car goes on dyno tomorrow then back to track friday

 

Car looks great. Who makes those wheels...I like.

Have you ever tried Pinnacle Carnuba on the black car, I was looking at it yesterday.

Paul

 

Thanks for the compliments Paul....The wheels are Volks....and I have heard of Souveran but never tried it.

J

 

Hot Car master Jay! Hope you put some good numbers.

 

Umm hi VRP package! !! Great looking car man!!

 

Those coolers are scary...I put my hands to them under a full run...warm as a baby's bottle...

 

Dyno

 

 

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.

 

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

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

 

Results from Custom yell smurf CAI on SL65 w/aftermarket tune, I like it besides dorky filters...


Dyno, said it made 30rwhp after install.

 

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.

 

I wanted to add some data...after going over the files in Winpep, I gained a peak of 38rwhp on the 3-4 gear shift

 

Thanks Marko! that's what I figured, the kit requires ecu tweeks to adapt to new IC's etc..

 

As I always say "dyno-shmyno"...the real test is the track...I will have data for you guys by mid-day tomorrow.

 

I totally agree w/you Jay, but do love to see krazzeee RWTO #'s on these motors! kudos for getting data so soon

 

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.

 

I hear you on the early torque band, but disagree on roll-on ferocity Great talking to ya on phn bud! good luck tamara!

 

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?

 

+1
SICK ride.... Definitely one to be proud of...
