I had said in another post I would post my dyno sheet, but had not gotten around to it because of my recent illness/surgery. Here is the Dyno sheet. This is RWHP/torque. The only mods for this dyno was a Veloce Performance ECU tune, renntech headers and K&N filters. This is a 93 octane tune.




Below are my new purchases that are waiting for install. 170mm overdrive pulley, phenolic spacers, dedenbear ic pump, dual pass custom heat exchanger.

wow, what was your baseline? regardless, i think your dyno operator is playing a joke on you. i'm not in any way questioning the mods but those numbers are EXTREMELY inflated for the few mods you have and especially for being measured on a dyno dynamics machine.

not trying to rain on your parade but i'd have to see 1/4mile times backing up those numbers before i put any faith in the guy that performed your dyno work.

Sunny55

Dyno Dynamics numbers are typically lower than Dynojet numbers. With the mods that you state, I think this is the highest I have ever seen or heard of.

I have to say WOW too....that's really really high for just ECU and Headers.
I'll be happy with 480-485 rwhp on a Dynojet, with all the mods that i've done (Kleemann K2, air filters, phenolic spacers, IC pump upgrade).

Anyhow, it's impressive, but kind of hard to believe and without a baseline dyno, you really can't see how much you improved over stock.

Mike:

You should come out to the track when I am running PIR w/the SL55. I would be happy to give you a ride. All I have is our ECU work and K&N filters. It is very strong! Your beast is running strong, but I didn't want to do that much to my car....and I knew that there was alot to be had by just tuning.

Everyone wanted proof. Thank you Doc for getting some!

Yep,those numbers are way off! Proof? No,I dont think so.

Sorry, had to dig and found one of my drag time slips. It is 1/8th mile on street tires with tirespin in 1-3rd. My new street tires are now 2 inches each side wider now. Have not taken to a 1/4 mile track yet. there are very few around here. Most are 1/8 mile tracks. I am recovering from major surgery and next track days won't be for a while. I will update when I can.

chiromikey

i'm not good with 1/8mile times but i don't think your mph is up to your dyno measurements...BUT are you saying you ran a 1.668 60' time on street tires with wheel spin!!!!! you've either got the baddest launching 55's i've heard ever of or something isn't adding up.

chiromikey

i'm not knocking your ecu work at all but those dyno numbers are huge for a dyno dynamics machine regardless of mods.

btw, i'd love to catch up with you at pir...just say when.

alroumi

Great no's , enjoy your faster sl and now for the Cam's

I apologize the 60 ft time is a typo. It should be 1.768. Yes On street tires Toyo Proxes T1R 285/30/20. Yes wheel spin galore. My SL55 kicks my sl600's a-- and it is renntech tuned. As far as something not adding up, what do I gain by making up numbers. I have better things to do with my times. The 60 ft time was a typo. The dyno numbers are true when compared to the other local dyno. I have not dyno'd at both, but It is a new dyno and the numbers on my friends cars who have dyno'd in 2 different locations were actually very comperable between the 2.

JAYCL600

I dont think anyone is doubting you or your car, im sure its fast and u enjoy it, i will say though that if your 55 with just headers and tune kicks your renntech 600's butt u need to get another tune on that 600

i have said this before, this is NOT the first dyno dynamics to read abnormally high, as the HP is further evidenced by the 1/8 mile trap speed which would put him at a 115+ trap in the 1/4, sometimes the best "dyno" is your trap speed

One thing I really believe is what Dino says. Veloce has been perfecting the amg55 motor because DUH the owner drives one. So they have found every little bit of Power without the pulley. I am curious to see how it does after I add my new pulley.

As far as needing another tune on my 600, I agree. To be honest I am not very impressed with Renntech. I could have had the headers ($5000) made by my fabricator buddy for less than 1/10th of what they cost. There really was no super intuitive concepts in how they were designed. They only get 50hp from tune and pulley and I KNOW I got 40+ from the Veloce ECU tune without the pulley. But sometimes it is just the right combo between the way the ecu is tuned and the headers/CF intake. But the intake was added after the Dyno/drag time.

Timeless

Those are some great numbers. I'm really itching to get this done to my car when I can find the time.

Dino needs to run a group buy on the ECU tunes.

Tyler Durden

Agreed; without a baseline dyno, the results don't mean nearly as much as they would with the baseline to compare it to. Think of it the same way you would a diet, except you didn't know what you weighed to begin with, you may be happy with what you have now but it'd be a lot better knowing where you came from to begin with, would you rather KNOW you lost 2 pounds...or 20?

I have excellent access to a Land & Sea dynometer which uses Dyno-Max 2000 software. When I do mods I'll be more than happy to do a before and after, and post the numbers, it's just a little difficult, at least as far as selecting the tuner themselves is, to pick one to begin with. Big difference between a $400 SCT handheld tuner for my truck and thousands for a friggin' ECU tune...

chiromikey

i never accused you of anything and i'm sure we both have better things to do with our time. i simply said something doesn't add up and obviously i was right...1.768 is easily believable for the situation where as 1.6x was not so thank you for correcting the typo.

just for comparison, you're putting down slightly more hp than i am on a dyno dynamics machine but my 1/8mile times are 7.4x @ 94.x mph in worse conditions. BIG difference.

Jrocket

Nothing you or Veloce has typed on this forum has added up.

I know how to end this back and forth.

Dino should flash his car back to stock, then dyno the car.

Then immediately flash to his latest program and dyno again.

Post the dyno's ... end the debate!

My 1/8 mile times are at a backwoods 1/8 mi track that is basically someone's back yard. No track prep on the day the time run. Wheel spin from 1st-3rd gears so you running faster times is no surprise. See if you can even find it on a map. http://www.baileytondragstrip.com/ Next time I am able to go it will be on street tires but with 4.6 more inches of rubber on the ground. We will see what the numbers do. And there is no way your conditions can be worse than this track.

Murtaza

Your 55 is making 550hp from ECU + filters alone???

rbtronnie5

now this is just insane...so you are saying your renntech sl600 gets it's *** kicked next to your 55...lol

rbtronnie5

he always has small typos...the 60 foot time for example....or maybe how in the pics section he said his wheels were 9f's 11r's which is obvious they aren't...then tries to sell the wheels and states they are 8f's 10r's...hmmmm

chiromikey

sorry but i find it hard to believe you're getting wheel spin through the entire 1/8mile (1st-3rd)...ESPECIALLY if you want me to believe your 1.7 60' time. if you had anywhere near the wheel spin you're stating you'd never break the 2 second mark on your 60' time.

regardless, i'll put our da conditions against yours anyday. there are only 2 places with worse conditions than arizona and that's new mexico and denver, but at least denver doesn't have sand blowing across their tracks like the desert states do.

you should try to find a 1/4mile track if you want to compare more meaningful data.

ROCafella_M6

Those numbers are ridiculously high for and 55 with just ecu, filters and headers on a Dyno Dynamics machine. Plus those dyno numbers mean pretty much next to nothing without a baseline dyno. Anytime you tune your car, you should get a baseline dyno first. Then after the mods, go on the SAME dyno machine and do a few runs and then compare your baseline to your modded.

erdocslx2

I honestly can give a rats A-s if you believe my numbers or not. As far as the wheels go My HRE's are 9F 11R, The Ones for sale now are 8.5 F 10 R. Get your facts straight. I have like 5 sets of wheels between the sl55 and sl600. as far as conditions, I was talking track conditions, not weather conditions. Your not telling me anything I don't know about Arizona. Coronado High School grad (Scottsdale). But dry hot air is always easier to compress then moist hot air. Gotta love Boyle's Law!

I do not care about the numbers. I thought this was a friendly forum, not a keeping up with the Jones' forum. Some engine builders/tuners get more power out of the same equipment. I was just posting my data. I really do not care what you think or if any of you believe them. If they are that important then you see my location. Fill it up and we can hit the streets!

I have no personal experience with Renntech, but somebody there sure makes some serious money..! If your 600's butt's getting kicked from your 55, something's terribly wrong over there..!
Sweden sure is a place way of geograficly speaking, but I feel sorry for you spending that kind of money, and still be disappointed with the thrust on your 600...
How much did you spend on this so called "tune" anyway..?
I can tell you, that you will not be disappointed if you go with the same ECU that I got from Tumba Turbocenter in Stockholm...
Just read my thread called "My latest darling", and you'll get some info on one Monsterchip... Trust me.
And, PM me if you're interested.
