SL55/63/65/R230 AMG: **Dyno** LTH, 180mm, Tune
We started the mods monday, but due to 2 bad I/C pumps and a blown relay It made more a boat load of time chasing our tail. To only realize the dealer sold me a bad I/C pump. We were able to pin point it to the new pump after some tests. I was a little upset, because I hate working on something twice. I almost even questioned, if I should have stayed away from modding.
After many aborted runs on the dyno for high IAT's we go the issue resolved. I have to say... If I ever have to strap down another car on the the dyno. It better not be for a long time.
As I said before, My only mod was long tube headers. Then I mated that with a 180mm pulley and a Dyno-Comp custom matched dyno tune for 91 octane. I have to say I was expecting the peak power to be around the 500whp area. However the torque very much exceeded my guess.
I can't wait to get this car out to the track. Maybe some street tire passes this weekend. Next up throttle body, H/E, Airbox, and whatever else crosses my mind.

But then again, you know how I feel about dyno numbers. Great gains though! Let's see some trap speeds now!
BTW Clayton, congrats on the new record. You deserve it.
Can't wait to see your traps. Your car is making some serious power!
BTW, I dyno'd at only 484/610 on a Dyno Dynamics, last I checked.

But that was before I switched to my Jeremy tune.

SL55 headers? not long at all. we've gotten pretty good at making SL55 headers fast. I'll have the H/E next week.
I'm just leaving to head home for the day. Give be about an hour and I will PM you.
It is a road course, so you will have to negotiate corners, rather than step on the gas and 'hold on'!
I have had the SL55 on road courses and it is actually very good. The last time I was out with the other instructors, my 55 stayed even with a Z06...... lap after lap...... until my brakes went away!
You can't quite overcome 4K pounds, but it is huge fun, and challenges you, your car, and you can get a tan.... which is tough when playing on a dyno!
