E46 M3 Cab Dyno Results

[tjw110]

I went to a Piston Heads Dyno day on Saturday, usual questions raised about the accuracy and calibration of the equipment, oem E92 M3, E60 M5 ran bang on BMW quoted figures, managed 364bhp with a quality map and induction, and after keeping up with another E46 M3 coupe in a 60 mph start 3rd gear drag race, am very happy with a healthy engine

Apologies for the error in the title should read E46 M3 Cab

Was a little confused there for a minute! I was thinking the 364 bhp was the figure at the wheels for the E90.Not a bad result for a E46 M3.

364 bhp sounds too high. What is the wheel power?

Obviously there is always the question of accuracy but as the 4 standard cars ran exactly standard power you can't go too wrong with your results. My E61 M5 was bang on, the E92 M3 was bang on, the Leon Cupra was bang on and your mates M3 Coupe was also pretty spot on. I'd be pleased with your map!

Nice one Tyrone

Was this with the "off-shelf" remap chip you had?

[tjw110]

The remap was done by AAT, K&N induction - happy with the results

[Mr Bimmer]

Have you got the wheel power results and a scan of the plot?

[tjw110]

My thoughts on the credibility of these results are based on the other high spec M powered cars hitting the BMW quoted outputs

What was the power at the wheels?

At the fly is only useful in the pub.
