so I dynoed my car today on maha....

i used normal fuel from first fuel station like always (fuel in poland is a huge issue as we have here "fuel mafia" for more than 15 years so the quality is poor, in Germany fuel is 10 times better), no methanol or some other special stuff.

please notice that measurement is finished at 297km/h as 300km/h is dyno speed limit.

here is one more with higher load, we stopped earlier as this is high stress for engine.

during all power tests on 6th gear my intake temp rise only 10C

Wow, Great numbers!

Do you mind clarifying how long did it take for the dyno run, how fast was it? To get these torque numbers on a properly loaded MAHA you must be running 2 Bar of boost or more ?

Sorry I am not familiar with your engine build, and you could be running N/A compression rather than turbo engine compression? Otherwise it is very unlikely to make those torque numbers at less than 2 Bar..

Just trying to understand the numbers, I am not doubting them at all. They are fantastic.
Edit: just realized that since it is in 6th gear the torque numbers would be higher..but not by much I think.

here is picture of one of the clutch sets I have tested.
it's clutch masters stage fx400, it was working 2 days, no hard launches, it start to slip on the 4th gear during acceleration.
springs start to play immediately...

The resistence of the MAHA rollers under full load makes it very difficult to get any grip and have a clean run, I have experienced it at Manthey so have other forum friends with high powered engines. The dyno sheet mentions 1.5 Bar and -2 degrees C, I am guessing those are not accurate.

why not?

it's 1,5 @ 3000 and 1.15 @ 7000.
I'm not using any external boost controller.

hmm..my ecu guy is doing a lot of programing for Manthey.
