If there is any interest ...

On Saturday the 21st of June, the team at VCM Performance/Magnuson Superchargers Australia are offering to host an AMG open day to their Autotechnique workshop, and run some cars up on the Dyno.

The suggestion is to meet at their Knoxfield workshop at ~10:30am for a look around & chat while some of our cars are given a run on the Dyno (4WD Mainline). They might even put a few sausages on the BBQ for a light lunch, and then we could trundle off for a cruise through the Dandenongs to a nice bakery for some coffee & nibbles in the afternoon.

There will be a token-fee of $75 for anybody wanting a dyno run. There will be a limit to how many cars can be run up on the day, so they will be done in the order of registering your interest below.

Please indicate your interest by replying to this thread.

Any figures?

Southways

There were three cars dyno'ed (including mine). From memory, results ranged from ~270rwkW to ~310rwkW.
It was really good to put some faces to names.

hi
any details mods & performance thanks

Southways

2103 Coupe P31 with ceramic coated IPE Headers, OE Tuning calibration.
No other performance enhancements.


310rwkW (4th gear, Dyno mode, repeatable on different days on Mainline dyno).

I'm assuming you meant 2013? Interesting if it is. Shouldn't they make more with headers and tune then a regular c63?

Southways

Yeah - 2013. I tried to pre-order a 2103 but the local AMG dealer seems reluctant to commit to a price for the FTL-drive with the cloaking option.

The numbers shown are at the wheels and are definitely more than the regular non-P31 ... up about 50rwkW (67rwhp) than one we tested a little while ago.
Also, the Mainline readings are quite accurate ... not as "happy" as some dynos.

RNS-11Z

What I meant was, a non p31 c63 with headers and tune dyno's around 310-320rwkw on mainline dyno. A p31 with the same mods, I assumed would make more, especially an 2013 p31 vs 2008/9 non p car.

Southways

The lighter rotating assembly of the P31 will benefit acceleration & durability, but I don't know of any other mechanical benefit the P31 option offers that will result in a better dyno number when both versions are recalibrated.
Is there something else the P31 has?
Are the cam profiles the same?

RNS-11Z

Apparently 2010+ spec cars have a different cam (I might be completely wrong here though I remember reading on this forum that the part number through the dealer confirms a cam change), how ever you are correct between p31 and standard car only the rotating assembly is different.

Southways

It is my understanding that the cam material was changed due to premature wear (quite a few early engines had cam/lifter issues).
I don think the profiles changed - happy to be corrected.
