Hot day little fan. 3rd gear 4 5 th would be higher #'s

Your pushing 630WHP?? Where is the chart you attached?

The numbers seem really high, even for a chipped 65. Should be around 580WHP...

Autoscope

Really, I was under the impression that upper 600's were about right! I will say, our dyno's are VERY conservative and the owner said he has dyno'd like 730ish on a different dyno in DFW. I wonder if he will chime in....

I am trying to get the graph.....

Your dyno charts didn't attach to your post. Please try again.

Kleemann 65 amg dyno 2 stock 3 upgrade runs.pdf

630 hp / 762 Tq Rearwheel that's why you Kleemann a SL 65 , not a 600 or a E55 , all nice but not comparable .

I'm sorry, what does a 600 or E55 have to do with anything?

TMC M5

If I am not mistaken these figures appear to be done at the Kleemann USA facility in Colorado Springs, CO. Who hand wrote all the commentary on the side? When I was talking to Cory at Kleemann he mentioned that they report all their dyno hp figures at the crank. I think that is what happened here. All those figures are all at the crank....which isn't bad considering that Colorado Springs is 5,000+ft above sea-level.

My friend just had his Kleemann S600 dyno'd a few weeks back and got 465 HP, 625 Ftlb Torque to the wheel (on a dyno dynamics dynometer). My stock S600 got 450 HP and 560 Ftlb Torque on the same meter last weekend. The gains don't seem as impressive as I thought they would be. I am thinking about going Renntech.

That was like Emiril L. BAM! BAM! I knew these #'s were & not remotely possible @ rear wheels w/only ECU Care to drop any more pearls of wisdom jg8881 Everyone here knows Kleemann's in house dyno reports corrected Crank HP/TQ readings, welcome to the club 600 & E55's are every bit as potent when modded by Kleemann.

Take a trip over to Dragtimes........ & puruse all the Dyno & 1/4 mile data for all (3) models N' report back M' kay.........

Akademiks

Wow. Are you sure his 600 isn't suffering from some cooling problems?

Marcus Frost

Impossible your stock S600 did 450rwhp on a dyno dynamics. On a dynojet, yes, on a dyno dynamics. Not a chance.

I believe your friend dyno'd his S600 on our dyno day here in Chicago, and 465rwhp on a dyno dynamics is a VERY strong ECU'd 600.

I have dyno'd almost a dozen of my own personal cars (including a RENNTech SL600, and a stock SL65) and seen countless others on dyno dynamics. 450rwhp is not possible for a stock 600 on DD.

TMC M5

+1.. although I was under the belief that a DD can be set to read like a Dynojet. I think the load setting that supposedly comparable to all dyno dynamic #'s is the "shootOut" mode setting. So maybe the same dyno had a different run setting on that particular day...

I was feeling a bit bad cuz Treynor's did 480 hp on a different dyno on dragtimes. I didn't think there could be that much difference between dyno's.

Marcus Frost

I know what you are saying Tom, but any dyno can be made to read anything, corrections can be off, all these things are inherent to any dyno. I probably should add a legal disclaimer to my strong language

Thericker

I've seen multi stock 600 dyno's Treynors S600 was the highest @ 480 rwhp, the average is 450 rwhp & 550+ rwto on Dynojet... Your S600 is indeed healthy

Reckless

Marcus: You had renntech SL600, would you go Renntech again or would you go Kleemann (if price wasnt the issue)? I wanted to come that day you guys were dyno'ing, but had prior commitments. Hopefully, I'll see you guys at the next event.

Marcus Frost

Reckless,

Thanks for the graph, but I'm sorry to tell you, either your S600 isn't stock, or something was up with the dyno when you made your pass. It's strange that it's CPT, who definitely knows how to dyno these cars, so I will have to ask Al.

As I mentioned before, I've dyno'd quite a few cars at CPT, have organized two AMG dyno days there, etc. I've seen a LOT of AMG cars dyno there, so I know what numbers they should make.

Here are some other comprable figures from that day to put things in perspective

Stock 55, 400rwhp (Rated @ 500hp)
VRP600+ E55, 464rwhp (Rated @ 600hp+)
ECU'd S600 465rwhp (Rated @ 627hp)

My SL600 RENNTech and SL65 both dyno'd in the 440 range with failing water pumps as well, but if they were running 100% I'd put them in the 450-460 range also.

-m

Marcus Frost

I'd go Kleemann. RENNTech has way too much ego, and you can't just say price is not an issue. RENNTech products for the price do not deliver something that is more than their competition. Even if money isn't an issue, the principal of a company doing that bothers me. I will say that Bob @ Renntech is somewhat ok to deal with, but it's not enough for me.

On the other hand, Cory @ Kleemann is always prompt, cordial, and he is extremely knowledgeable. Klemmann makes a good product and while they are not perfect (NO ONE is), they work hard when things go awry to make them right. I would not even consider RENNTech again for my cars at this point.

Any reason why you're choosing Kleeman over Renntech for your SL600?

Thericker

+ 1000 on what Marcus has noted as well as current pricing for Kleemann ECU/TCU is only $3k the RENNtech equivalent is North of $6k last time I chk'd

Independent dyno's prove they both make the same power, if they were equally priced I'd still go Kleemann (I've read a few past RENNtech tunes made less than advertised power on members cars here) Kleemann seems to be on point

AMGfan

Hard to beat customer service from Cory and Brandon...

E55AMGFan

Ahh ok! I've seen a lot of great Renntech 600/65 cars on dragtimes but never a lot of tuned Kleemann 600s and 65s in terms of 1/4 mile and dynos. Of course we have the thread starter who posted his but those numbers but I prefer rwhp. I saw the sale they are offering on Kleemann stuff, and it's a steal as you're paying half price and getting the great power. That mean's more money to buy replacement tires once insta-torque kicks in. Please post your baseline and your ecu/tcu numbers once you get it done bro.

Reckless

Marcus: I just talked with Al and he did 3 pulls that all were in 440-450 range with same settings as the dyno day. I checked with my friend who had his S600 on the dyno (he knows my car in and out) and he said he is sure its completely stock. I do drive the car hard regularly, maybe the engine is starting to like it?

Right now, I'm leaning to Renntech, but I would agree with you that Cory is superb to deal with and Renntech is a bit difficult. Renntech claims they are the only one with a software programmer on staff. I emailed them my dyno to see what they would say. I would agree that if price is an issue, Kleeman would be the best choice.
