RENNTECH announced its new Stage 3 tune for the 2008 65 series AMG models, which makes use of what RENNTECH calls "next-generation ECU software" to get 695 hp and 890 lb-ft of torque from the AMG's twin-turbo V12. "Power will always be important to many customers, especially torque," explains Hartmut Feyhl, RENNTECH's president and ex technical director of AMG North America. "Our cars have always been able to make considerable torque, and have been praised in magazines for their drivability. Still, we are constantly trying to improve our product."

The latest software takes advantage of the increased power of the new engine computers, and offers a number of small improvements that add up to a big overall improvement," Feyhl explains. "It really is that next-generation sort of product that is much more advanced than what we were capable of offering before. Compared to earlier versions, our new software gives customers more power and better drivability in a way that is more reliable, smoother power curve, and even improves emissions and gas mileage." In addition to the software upgrades, RENNTECH adds a larger intercooler pump and secondary heat exchanger, as well as a pair of carbon fiber airboxes to improve the flow of cool air into the big AMG's V12. The intercooler system upgrades reduce air intake temperatures by more than 20 degrees, delivering more consistent power compared to stock and allowing RENNTECH to more safely increase boost throughout the rpm range.

RENNTECH's stainless steel sport mufflers (also part of the new package) produce a deep, distinctive growl that is suitably aggressive for a high-end luxury car. Feyhl suggests that his mufflers "let the car sound the way it is supposed to sound." With almost 900 lb-ft of torque available from the engine, RENNTECH's upgrades deliver a real, noticeable improvement in terms power and acceleration compared to the already impressive performance of the stock 65 series AMG cars.

I was never a big fan of white cars...but this one definitely looks great. I wonder if the new software improvements are also available to the W215 65's?

Tom

 

Absolutely stunning!!!!!!!!!!!!!!

 

the amount of power these things make is sick

 

VRP has one that is making 1000hp.

 

Those are the biggest brake calipers ever! Car is so sick too.

 

Any more info on that VRP tunned 65??

 

about 6 pages here: http://www.mbworld.org/forums/showthread.php?t=222124

 

this car does not make 1000hp, its a 65 with a different intake and larger intercooler cores and hasnt even been dynoed yet. Their goal is to make 1000hp at some point, we are basically just following their R&D as nothing has been tested.

 

The intake looks like it has lots of promise. My only question is...why did they post it in an E55 thread?

Tom

 

because that is basically where everyone goes to look for performance, its the most popular section on MBWorld

 

Knowing Vadim and Victor, it will....soon.

 

soon is a relative term
