Here my more or less pleasing result :confused:

One measured on a Maha LPS 2000

VSA off, 4.th gear, 31600km, all OEM

Only which makes me happy little is the standard achievement 149,5KW/203,3PS makes already however which a little sad me it the 187NM(137,9 lb/ft) [smilie=cwl.gif] 6NM(4,4 lb/ft) less like series That it can be appropriate which I only 187NM has

Indeed. Stock FN2 are between 205-212 HP, so nothing to worried about, but you had a really good air temperature there.

@ pottsy

how many lb/ft have your Type R

@ dawid

yes the air temperature is good 11 degrees, but the type r love cold air.....it's very differnt to sommer 25 and winter 5 degrees.

@ fat

But the Maha dynos already is with very exact… or?!

@ mike

As you unfortunately mean it with the 138, have it only 138 :(

I'm happy with the 167ps on the wheels but I'm very sad with the 138lb/ft, normaly the type r have 142lb/ft

But i think 167ps wheelpower at 11degrees not so very good, which wheelpower you like that reached and at which temperature… that is nevertheless so the more warmly the worse actually

No, the figure for torque is not exact, it is a rough guess.

The only exact figure is the power at the wheels (P-Rad). Then losses are guessed (roughly) by measuring resistance on the over-run, and these guessed losses are added to P-Rad to make P-Norm. This is an estimate!

The torque figure is then calculated using the inaccurate P-Norm.

Torque = KW/2/Pi/rpm*60

Looking at your graph, you can verify this. Peak torque is showing at about 7300 rpm, where P-Norm is about 140 KW. Use the formula, and this comes out at 186 Nm.

So the torque figure you are sad about, is a very inaccurate estimate using a dubious philosophy. The only accurate figure is P-Rad, which is fine.


PS - torque curves on dyno charts are useful, but the tuner uses the shape, not the value. The shape of your curve is perfect.

I have a little question :)

Ist the 5.th gear better than the 4.th gear?

A user in a german forum say by 5.th gear you have mor PS and NM, because of 1:1 translation relationship

Better is make a dyno on 5th gear, but honestly it doesn't really influence on power & torque.

4th or 5th on the FN2 doesnt show much diference in top end power.

But the closest to 1:1 its 4th!

fn2 gear ratio

1st=3.266
2nd=2.130
3rd=1.517
4th=1.147
5th=0.921
6th=0.738
reverse=3.583
final=5.062


usually when you have 5 speed gear box 4th is closest to 1:1 and for 6 speed gear box is the 5th.

Property times a small calculation made, with these initial values
fn2 gear ratio

1st=3.266
2nd=2.130
3rd=1.517
4th=1.147
5th=0.921
6th=0.738
reverse=3.583
final=5.062

thus speed ratio 1….measured should actually in the 5th gear. So 1 - 0.921 = 0.079 .......... 4th gear was measured there here 1.147 - 0.079 = 1,068 this value then times PS and NM, comes then P-Norm 217,1PS and 199,7NM In such a way cannot does one think it not count :) but see paying already better out gives it a possibility it to project it there the 5th gear would be?
