SL/R230: Difference between Maybach 57 & 600 TT engine...
the article also went on to say Mercedes severely DE-TUNED the 600 engine to keep sl55/65 sales up!--------------------------------------------------------------------------
But the 600 TT is still highly underrated in stock form....I found this too
--------------------------------------------------------------------------
481.5 rwhp OEM... that is just amazing. We are TRULY in the golden age of automotive performance. car will SMOKE virtually any of the factory muscle cars from the 60s and 70s. a VERY quiet, VERY refined, VERY fast beast.
Regarding drivetrain loss. The smoother you make a car and the stronger (heavier) the components (hint: this is a heavy smooth POWERFUL car) the greater the drivetrain loss. 15% is a reasonable number for a NON IRS rear wheel drive car with a manual transmission. Most luxury cars in this class have a least 20% loss and can be higher (4wd). 22% seems exceedingly reasonable.
22% loss calc: 481.5 / 78 x 100 = 617 flywheel horsepower.
also, 718 flywheel torque
This 600 TT car engine appears to be underated by OVER 100hp and 100tq

was a big part in my decision on what Mercedes to purchase nextI gotta keep my modding plans on the down-low, pm me for my latest up-coming modzzzz.

BTW do you still have that lower T-stat for sale? what gains would one expect to get w/that? besides obvious less heat
any more HP to be had w/it?BTW....Did you ever get any dyno charts? love to see your rwhp/rwto

. To be honest, I'd really rather not spend 5-6 grand to do it though. I've been doing research to find out the best bang for the buck on the tuning but I continually come accross conflicting information. From someone who's been there, done that (E55JAY) and from someone who's looking such as myself (Thericker), what do you two guys think? I know this question has been posted many times before on these forums and I have actually pm'd AdamG with Evotech, but there's been chatter about him no longer being in business? I just pm'd him 2 days ago, so maybe he's just not had time to respond. Don't hate anyone, just some things I've read....I know nothing about AdamG nor any of his business dealings.
This dyno is the only one that I have that has a TQ reading. This was done by the previous owner in Oklahoma after the original modification of the ECU/TCU, this was the only modification to the car at the time. As you can see it was conducted on a Mustang Dyno and made 481rwhp 658rwtq uncorrected and it corrected to 517.5rwhp 708.1rwtq

The owner traded in the 600 for a 65. For some reason the dealership took the car to another dyno to have it tested. At this time the car was suffering from a faulty intercooler pump but no one knew this. You can tell the car bleeding boost due to high IAT's by the dyno numbers. This was conducted on a dynojet which reads slightly higher then the previous mustang dyno so you can theorize the HP loss.

Upon delivery the car had a host of electrical problems that I immediately got fixed, at the dealership they scanned the ECU and found high IAT codes and replaced the stock IC pump with a new stock one. Ironically at this time I didnt know these cars suffered from this issue. The drove like a beast and I decided to take it to a local dynojet to see what it would make here in MD. The below are uncorrected figures done slightly above sealevel 60 deg F. Dyno operator was not able to get a tach signal. 525.44rwhp which evidenced the HP gain/loss from the bad pump.

Next I changed the airfilters. I went to same dyno as before, temp was 19 degrees hotter and I baselined 512rwhp, I then took out the old filters and installed my k&n's and put down 522rwhp for a 10rwhp gain. I have misplaced that actual dyno run.
Next I changed my exhaust, went back to the same dyno in almost weather identical conditions as evidenced on the dyno sheet. I made 537rwhp picked up 16rwhp peak to peak and 32rwhp under the curve.

Next I added the large water reservoir to the trunk for ice. I will re-dyno at some point, I think maybe I make 550rwhp+ 720+rwtq with ice water in the veins but thats just theory for now.
What did you notice before you "replaced the stock IC pump with a new stock one"?

I just sent you an email. With the intake air cooling system on the biturbo being water to air like the kompressor cars, aside from changing the pump have you added a larger core? I just had this done on my 55 and the proof is in the #s, I know that the biturbo cars don't have the problems of having a ****ty IC core being mounted under the blower, but it seems like from what you are saying IATs are a problem. What are your thoughts on a Johnson pump and a nice big core?
