What i think David trying say is saying is to not live on the dyno numbers...do a pull right next to another M3 who dyno's higher and do a comparo like that aswell...

I like doing a dyno testing (bone stock and with mods) and do pulls right next to a stronger car that dyno'd higher and see where your at...

I think u mean 4th gear, Alex dynos the cars in 4th gear not 5th. And dont worry Gintanis dd dyno reads low, 310whp is about average for stock.

yeah, probably cause he wouldn't want a car going 180mph on his dyno lol... most places do a 4th gear pull for safety purposes...

here are the gear ratio's for the 6mt E92M3

Final Drive 3.64:1

1st Gear Ratio 4.23:1
2nd Gear Ratio 2.53:1
3rd Gear Ratio 1.67:1
4th Gear Ratio 1.23:1
5th Gear Ratio 1.00:1
6th Gear Ratio 0.83:1

red line is 8,400 rpm as you guys know.


so yeah... technically 5th gear would be the "correct gear" to dyno in for accuracy but, like i stated above, not many dyno shops will do a 5th gear pull. personally, i did my car in 5th gear and all it told me was my car reads 175 but i'm really going about 165mph
