Hey Guys...

check this out

Base run:

473whp
532hp at crank
633Nm / 467 ft lb torque at crank...

Preparing Stage 1 "as we speak"...

Stage 2 hardware is ready and will be installed and tested in 2-3 weeks from now

Cheers from RENNtech Germany!

What is the stage two hardware?

I would be very surprised if anyone has this info yet...

We naturally won't share any details yet...

But after testing and testing we can finally share some current STAGE 1 / ECU TUNE dyno numbers...

Expect more to come very soon

Great work.

Now those numbers are respectable. Much closer to what I thought would've been stock on this GT.

Well, STOCK it's approx 25hp over given stock numbers... on 102 RON Octane we have even measured another 7-8hp more...

Higher hp than latest US price list 532 vs 503 but slightly less torque 467 vs 479. Curious why the lower torque. Maybe some type of measurement variance?

Seems to be due to the delivery mapping...
You can see it's also building up the torque quite late so it drives like a NA.
Maybe also so it doesn't put too much stress on the DCT.
Different torque trend to the C63 BT ... https://mbworld.org/forums/c63-amg-c...ps-806-nm.html
Our dyno is very exact when it comes to calculating the losses... and it is frequently calibrated by TUV so we can use the measurements officially for the paperwork.
Sport Auto also just released a measurement (Test against the Porsche 991 Turbo) and they had measured around 640Nm and similar power ...
I would say: the may torque figure is there within a normal measurement accuracy range, but it is built up later than it is supposed to be.
But for sure the car is not missing the power...

Tq/HP not crossing at 5250 is quite odd... Is it due to torque measurement in Newtons?

Impressive none the less.

As you can see, power and torque scaling is different (left / right scale)...
