Here you go, let the fur fly. Run was done on a Mustang dyno, numbers are SAE corrected, we had good DA but it shouldn't matter with the correction. Bone stock except for Monarch 20's. This run was done during the Eurocharger/LET tuning session in Texas yesterday. No ice or other tricks.

Unfortunately, we had issues getting the Eurocharger tune into my ECM so we'll complete that latter this week. The '07 and up cars are not as simple to flash. Another stock CL600 put down almost the exact same numbers.

Once I get the ECU flashed will dyno it again.

Gotta tell you these Mustang Dyno #"s are way off... Mustang Dynos should read lower than ANY DynoJet yet these are HIGHER than any DynoJet average stock SL600 not to mention 20" wheels rob HP/TQ EZ 20/20 less...

484.7 rwhp way high & even further off buy a good 100+ rwtq lol 669.4 rwtq NOT gonna happen on properly set MD dyno period even a high reading DJ will put your SL600 stk w/20" @ 420-440 rwhp 520-540 rwtq VS. true stock SL600 on 18"19" whls on DynoJet make 450-460 rwhp 550-560 rwtq @ MOST

These TQ #'s are so off it's not even funny, gotta say it Jerry what's up w/these #'s they don't add up remotely??? a bone stk SL65 would put dwn less rwhp rwtq on 19"s on properly setup MD...

And you say This MD is totally off

2003 S600

Yeah I got 490hp after my Kleemann tune on a DJ.

blazeone

This isn't my first rodeo, yes the loading bearing Mustangs normally read about 20% less than a DJ.

I asked the operator about this and he stated he had the dyno set up to emulate a DJ "regarding #'s". Other than that you'll have to ask Jerry.

I'm going to have my car dyno'ed on a Dyno-Dynamics also in a week.

Thericker

Jeez...This info ceratainly sheds some light on Busa's S65 tuned on this exact MD made unheard of 840 something rwtq on otherwise stk S65 I knew something was off Thank you for posting Blazeone

Stock rwhp Vs. any high reading DJ is off by good 40-65 rwhp, especially rwtq by EZ 120 rwtq considering you ran w/20"s

Stockers make 560 rwtq MAX on 18"-19" whls on HIGH reading DynoJets

blazeone

Jason who I've known for years has got the same numbers on two other dyno's here in Houston. Also he ran his S65 to a 11.54 @123mph bone stock with DR's.

I'm not going to defend the #'s as they seem high to me also but not nearly as high as some of you Californians Maybe your weak 91 gas and smoggy air f-up your hp

EVERYONE else please check out this link and note para 3.

Everything is bigger in Texas

Thericker

Ahh nope I've dyno'd @ (2) different DynoJets & (1) Superflow Dyno - read like MD's

My SL600 has mods noted in siggy, DynoJet #'s were bet 475-500 (500 was w/Ice on intercoolers for 40min in 95 degrees)

I used 94 octane mix on all runs...

There are numerous DynoJet records from all over the country, the STOCK SL/CL/S600 ALL fall in around 450-460 RWHP 550-560 RWTQ @ best

Thericker

Bro, you think your stock SL600 on 20" whls no less makes the EXACT SAME RWTQ AS STOCK S65 Come on man

Para 3. from your link... Busa's S65 results This is still high for ANY STOCK S65 you have no clue what your commenting about...

Dude the only thing that is off and wack is you... And you are coming off as someone with serious dyno envy... I have had my car dynoed at 3 different facilities on a DJ/ MD/ DD including Kurt's. The horse power numbers are all within 2 %. SAE correcting is standard at any good facility with an operator who knows what they are doing.. All of the track times on this car agree exactly with the dyno numbers.. So if Kurt's dyno was as "overinflated" as you say the car would not have been able to post the times that it does.

Maybe your tuners aren't that good, but what makes a good tuner great is to be able to start at a standardized base and use that information to record legitimate power gains (or losses) as opposed to variable gains like temperature drop, heat soak, change in DA, calibration, etc. Last time I checked there was not an official standard for dyno calibration so if you know this universal dyno by which all others should follow I am sure Kurt would be happy to recalibrate accordingly (and Jerry would also demand of the dyno operators at all of his tunes) , we would also need the standard rpm at which all cars should be stabbed at since that can cause torque numbers to spike hugely if done at just the right moment.

blazeone

Post one of your DJ charts. So your saying you have no tune "like me" and got 475-500rwhp and I got 484whp does sound that off to me. So you had 94 I ran fresh good 93 probably no diff at all. Our conditions were very good as approx 50F and high baro and low humidity. Although dyno's correct I've still seen better "corrected" #'s in good conditions.

The cars that were tuned showed very reasonable gains. A coupleof cars in attendance were prevously tuned and Jerry could not better the #'s and admitted to the owner.

blazeone

Why don't you quote the entire paragraph, your not a politician are you. Also, you can get over the 20's. My set up weights the same as my stock 18 factory crap. And yes I know about wheel diameter and centrifugal effects, etc, etc.

Thericker

Jeez here we go 101 dyno course, my SL has mods & you're running 20" whls shown repeatedly on Dyno to loose 20 rwhp. Do you know what CAI is? IC reservoir? exhaust work? Ice on Intercoolers alone has shown 25 RWHP gains, Jerry knows this & used my Ice trick & noted it while tuning another members S600 go look it up, I have better things to do w/my Sun...

You think your SL600 is making 110 extra RWTQ vs the rest of every known DynoJet reading in North America? Enjoy your fake puffed up #'s

Benz-O-Rama

I also posted this in the AMG forum where this debate is also going on...




This post is for comparison purposes only. Not getting into the dyno vs. dyno debate.

My stock SL600 dynoed, on a Dyno Dynamics, at 432 rwhp/530 rwtq

With a LET shelf tune, it dynoed 484 rwhp/610 rwtq on the same dyno, same day, same operator.

Track day at MIR is this Friday, so we'll see what happens. Unfortunately, I'll be running on brand new all-seasons, so grip will be a major issue for me. But, trap speed should give me a good idea of what's going on.

blazeone

Why do you think I put "let the fur fly" in my post. I knew this would start some poop. Once again get over the 20's you can't say that as a blanket statement. They ALL don't lose 20hp, it depends on wheel weight. How much are you losing from your 19's over the stock 18's?

Yes I know quite a bit about engines, I sell them for a living. CAI? oh let me take a guess - cold air intake Let's see intercooler cooling tank? ah that would be a device to cool down your charge air - duh!

Exhaust work? lets see - delete mufflers and straight pipe so that it makes more noise and less horsepower. Now that's a mod I'm not doing. But in all fairness sometimes one sacrafices a little hp for what they like.

Try to come off like you know it all. Oh, and I don't believe in faking dyno #'s by icing intakes, IC's or anything else accept beer.

I love this, keep it coming.

Wheels make no difference on a load bearing dyno but can on a inertia dynos. Your car on your dyno has no bearing on Blazeone getting a baseline from which to tune his car by. The common term used, is every dyno and every dyno day are different..Baseline is a baseline, it is used for tuning. Calling BS on TQ numbers , just shows a lack of dyno knowledge, as with the concern over wheels. It means nothing but just a number to tune by. If Blazone gets a tune and changes dynos, then he will not have a baseline, unless he used that dyno for a base..


TQ numbers can be affected by more factors than HP. One, depends on what RPM you stab the car.. This can show 100 more TQ alone.. It is damn tricky to stab these cars under 2500 rpm needed to hit peak TQ numbers. It can be done but takes know-how..



Nice Dyno graph on that 2007 SL600! Thank you for sharing your dyno results, from your dyno of choice !!

98aggie

Here is a dyno graph from a SL55 that was at the Dyno Day. This is a bone stock SL55.

Graph shows baseline and I believe a Stage 1 tune. Dyno numbers are spot on for this car before and after.

Sorry for borrowing this threat here on the DYNO topic.

I got mine powerchiped and then dyno tuned by my indy - BUT I have no ideas on what the "good" ones should be liked? All I know is that it seems (and feels) to have a lot more power and torque than before.

Here is my measuring at the wheels (are these diff places to measure?). I was wondering if anyone have an idea if this is good or bad on this 2004 SL600?

67supersnake

Dyno number are just numbers (but do reflect the power of the cars' side by side). My 67 Mustang WILL take the SL 600 from 20 to 140. But from 0 to 100, the traction control WILL make a difference if you do not know what you are doing. From 140+, the SL600 has the advantage.... but then... how much is enough?

Nice collection, love that Snake!! Hp & TQ almost the same!

I don't see what the exhaust comment is about, on an sl600 they are a flow through muffler, so it doesn't produce any back pressure either way, just changes the sound, it only changes things if you go with a bigger diameter pipe or a hi-flow cat
