Diff 3.64 vs. 4.10

**alexk** · 07-07-2010, 12:22 AM

This info is from Manos. He lives in Crete in Greece and has an M3 that is fully changed to CSL specs (all carbon bits etc).
I think he is member also here but doesn't post. He tracks the CSL so he is a capable driver.
I would like to thank him for the info.

The tests are in the same place, same temperature and weather.
With red is diff 3.64 and blue 4.10.
With the 4.10, the car also has SS race cats, and SS lightweight race backbox.

0-100 km/h 1.3 sec difference (3.64 faster)

The car is spinning a lot with the 4.10

0-160 km/h 0.7 sec difference (3.64 faster)
With the 3.64 you have 2 gear shifts and with the 4.10 3 gear shifts.

0-200 km/h 2 secs difference (3.64 faster)

100-200km/h 1.4 secs difference (3.64 faster)

80-110 km/h only here 4.10 is faster

0-400 m 0.5 secs difference (3.64 faster)

Redo the graphs to eliminate wheelspin...

From a standstill the 4.1 version hardly moves for a while, then look at the 1-2 gearchange and how long there is no acceleration, wheelspin again.

Maybe the ss cats caused a slight loss in power????

I wouldn't be surprised.

Too much wheel spin, for a realistic test. He needs to learn how to drive, or get better tyres.

Comments like these are not necessary

He is running cups and he definitely knows how to drive.
If the road does not have 'dragster strip glue', that's another story.
