Here are the first 2 pulls as the rest got progressively worse.

Nice little dyno. Brand new dynojet 248.

Of course with it being a Benz, the whole shop has to stop and watch. Mouths wide open as she pulled 462 first pull and 455 on pull 2.

What a friggin car. This guy had a Camaro with tubbing and all that *****.....the guy running the dyno told me mine pulled more hp and boatload more torque that he did.

Only downer if any is that those are corrected numbers for sea level just like Klee does. Acutally rear wheel at elevation was 395.

***Air fuel ratio question.....we started with around 14 at about 2000rpm and she went suuuuuper rich up to redline down to about 10. With an A/F of 14.....that's a little to lean to be thinking about NOS system isn't it? Any input would be great.

Overall again, the Benz impresses, I am happy and life is good.

Scan sucks, but least you can see the numbers.

AMG BLISS

Not too shabby at all. And to think for so long you were worried about the altitude.

So uh, anybody want to race?

Numbers don't look bad at all. Would like to see your AF graphed before you start thinking about a dry shot of N20. Also, a datalog of the injector cycle would be nice to have as well.

WOW!!!! You don't mess around when you say you are going to do something.
I expected a dyno in a couple of weeks, not 12hrs.

I think the dyno sounds pretty good. Now that you know you car is making the power, drive to sea level and find a track.

Jakpro1's one of those guys that likes it right now!
Why do you think he got one of the fastest sedans on the market, and made it even FASTER!

vrus

Nice numbers!!

Was I close or what...

I guessed 460rwhp and 500rwtq.. I did say though that I expected the K2 car to pull 515rwtq - 530rwtq which is bang on with your 529rwtq.

That is a very healthy beast you have. I hope to be joining that league of numbers VERY soon..

Enjoy the roasting power!

P.S-> I just gotta say.. damn.. 490lb/ft of torque at 2,000RPM!!! If that isn't a tire shredder, I don't know what is..

BoBcanada

what mods do u have? Kleemant stage 2?

E55_POWER

Jak, don't you have Stage2?

I got similar numbers with just ECU and Pulley from Renntech.

When I was Klemann S2 in my CL55, I pulled similar numbers as you did...I think your ECU may need repogramming.

Exactly

Where's the bottle neck?

BTW Jack, Nice BEAST

Jakpro1

I could have Klee check but one thing is for sure. The 5.5 has to have the biggest hp differences of any motor I have EVER seen.

Mine pulled right around 480 stock at Kleemann, while Gid_e_ups pulled 516 stock at Kleemann on the same dyno. That's a 36 hp diff.....if I had Gid's motor...I would have been posting rear wheel near 500.

Just nature of the beasts....wish I got the upper scale, but just didn't. 36 hp is no biggee though. I am happy.

Thanks for the input.

VelocitE55

Thats good power! You have yourself a mean car! Enjoy!

Were the pulls made under the same temp, bulb and baro conditions, same operator, same tires/wheels, same tire pressure, etc? All these variables can lead to a difference that big.

E552006

Correction factor "should" do away with most of these variables. I don't write DynoJet code though..
Tire pressure and wheel size could not create that much variation IMO. Unless you have some ultra bling 22s.

E55AMG99

I'm not sure the corection factor would take into account all of these variables. Atmospheric yes but the others, no. I've seen diffs of over 10HP with different operators and the same on the tire pressure as well. Add them together and you are more than half way to the diff here.

BlownV8

You made a little more than I had estimated but I wasn't off by much. You get the uncorrected RWHP up to 430 and you'll be running low 12's at your elevation.
