SL65 RennTech runs 11.07@128
My buddy Lou took his SL65 RENNTech to our local track yesterday. He beat his previous best record of 11.10@125. It looks like it's only a matter of time until he's in the 10's. The conditions were better than previous but still not ideal. The temp was 62f with 22% humidity.
He's running RennTech ECU, transmission module, CF airbox. He's also running 17" Bogart custom wheels with Mickey Thompson ET street radials. No NOS.

Damn! Any idea what the different mods gain? Stock I am at 11.7 so I am guessing the ECU brings it down to 11.4 or so and the drag radials the rest. Not sure what the airbox does, anyone? Great job.

Woah, that is an excellent time for any vehicle, let alone a 4500 lb one. Did you check out Brabus though, their ECU brings power up to 715 hp and roughly 800 tq (converted from 1100 limited Nm). I believe RennTech is 650 hp and 840 tq (Brabus is 65 hp more, but 40 ft lbs less). Both fantastic power houses of cars.

I wouldnt suggest Brabus.... Kleeman or Renntech would be the way to go. They both reach the HP/Torque claims that they have made. On average Brabus produces alot less, unless you want to speed a lot more money. To get the same power that we have on our SL from Renntech, you would have to spend about $10-15,000 more.

The CF Airbox gave a pretty good HP/Torque gain. The tires are really good, they help us launch better. That isnt our best 60ft time so far though. Currently its a 1.562 60 ft time.

question for lou, i am running 7.33 in the 1/8th with a 60ft of 1.71, i have ecu upgrade and bf dragradials, i use the dyno test mode for my burnout and for my run. what kind of gas are you using and are you in dyno mode for your runs or are you running with traction control? how did you get the 17inch rim on the rears? did you take off the stock rotors?

No the rotors are the same in the rear.. We had a guy custom build the rims for us. We do run in dyno mode and before we were running 104 octane but this weekend we are gonna try 109 octane and see how it runs on that.

the guy who made our rims is Bogart Racing Wheels. We are still using a stock exaust but we are gonna be trying a Eisenmann exaust here once it gets here. The CF air box gave us about 40 hp and 60-70lbs of torque increase. We got lucky cause they say it doesnt usually give that much of a increase.

i just installed the eisanmann sl65 sport exhaust today it sounds really good when you step on it. cruising speeds is slightly throatier, i changed my h pipe to x pipe. i was woundering if there is a big diff. in drag times by using 18in bf goodrich radials, to 17in mickythompsons? or is it the gas?

well fuel makes a difference.... we ran a 10.85@124 on 109 octane and with the mickey's you will notice a ton of difference, they grab so much better then BF's could ever dream of lol

Also, CONGRATULATIONS ON THE 10 SEC PASS. It brings a little tear of joy to my eye to see all these fast Benz's running around. Little did I know when I put the ECU in my '03 S600 and started running 11s, how quickly it would escalate.

how much did you pay for your wheels? 17x10 . i am trying 103 octane friday, i cant find 109 anywhere. did you have to run race fuel for 150 miles before the cpu adjusts to the fuel? i was told i need to let the race fuel cycle so the cpu can resest

When we started using the 109 from 104 octane you could tell a big difference with it. You dont really have to run it too long for it to adjust unless you use it for alot of casual driving.

If you really want to get fancy you might want to try CO2 spray on the intercoolers. DEI makes kits for this might give you the little extra you are looking for.
Actually in Air to Air intercooling those kits work wonders. But with Air to water intercoolers you have to use alot more NOS prior to the run in order to cool down all the water. At which in a day of racing you will most likely go through 2-3 10lb bottles. I have been speaking with a few people to see about putting in a racing intercooler pump to help cool it down some

Hey Joe, did Lou ever get his transmission done? I thought he wasn't gonna open her up until he did that?
Amazing time though... and that trap speed! close to 129!
edit: Sorry didn't see you were on the thread Lou, did you get it done?
