MBH motorsports

i've been mod sober for a while now, just running my headers and thats it. Keeping myself busy with MBH. So today the addiction overwhelmed me and the results were a gain of 98wtq and 58whp over my header only setup.

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.

Makes more on the dyno than mine.

But then again, you know how I feel about dyno numbers. Great gains though! Let's see some trap speeds now!

I have to get to the track. Last time I was there I was getting some body movement at the top of the track with stock wheels. I'm gong to once over everything to make sure the stuff is tight. The only guess I'll make as to what it will run is.. Faster than before.

BTW Clayton, congrats on the new record. You deserve it.

Benz-O-Rama

Thanks Mike, it's been a battle.

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.

thats some nice gains there

MBH motorsports

I know how it is.. I've been there and I've been following your ups and downs that have finally got you to this point. Sometime chasing a number is such a grind. I just glad people are still trying to push their cars. What are you running for tires at the track?

MBH motorsports

thank you.

265 width 18" Mickeys. They were good for a few 1.6x 60's, launching of very mild boost.

Nice gains! To think that's only a pulley, LT's and tune. Damn your headers speak for themselves.... Every time I see MBH threads it always has me wondering about doing some LT's and ditching my original plans with this car all together.

Just a side note: My brother who has a CLS55 just did the same mods Headers, pulley & tune. He made 505whp and 575wtq. I think I spent more time on the dyno letting my ECU learn up. I did a bunch of driving yesterday with a bad I/C pump. So my ECU was pulling timing. It literally made no power over just headers. with my bad I/C pump. So we took the extra time on the dyno to make sure the ECU was fully adapted. I wanted to get to 600wtq so bad, but it just wasn't meant to be, yet. Other than that it was very consistent on the dyno, with the stock I/C HE setup.

Still great numbers for a generic tune, I take it your HE isnt ready for sale just yet?

MBH motorsports

It will be ready very soon.

kustom2k1

Im patiently waiting on one, my cars in Florida and I'm in NYC until the beginning of Feb..would you consider that soon?

How long does it take for a set of headers for an SL55? Thanks!

MBH motorsports

SL55 headers? not long at all. we've gotten pretty good at making SL55 headers fast. I'll have the H/E next week.

kustom2k1

I know you've been in contact with Wade about the HE for me and next week sounds good, I can get the to get him for install. Now onto the headers, what do you need to get started on a set $$$ and whats the wait time after funds are received?

MBH motorsports

I'm just leaving to head home for the day. Give be about an hour and I will PM you.

MB_Forever

Very solid numbers Mike.... I wish it was that easy to get gains those types of gains on the 63 platform

here is a copy of my brothers CL55 dyno with the same mods

Since you are in AZ, Pro Auto Sports is having a Sat/Sun event this weekend.

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!
