Is this wheelspin / slip on the dyno ?

[M5 London]

Hey Guys,

Just wanted your opinions on this dyno run please ? :





It definitely doesn't translate into any drop in performance on the road....


Thanks in advance !

Can be loady

Youll know if its manipulated if both whp n trq doesnt intersect at 52-5500rpm. Imo

Cheers mate !

They definitely cross at 5252 RPM (where HP = TQ when both their scales are equal).

Just curious about the dip on the post tune run. I have some other examples of wheelspin on a dyno run and they have a similar dip to some extent.

Thanks

If your talking about this this could be from shifting 3-4 or 5-6. Somethingg like that. Here is my dyno shifting

Thanks but I don't think so as there were no gear changes once the car was pushing on with a power run on the dyno.

Quite possibly !

However the car is on 4,500 Miles and has been stock until yesterday when it got upped to about 620 WHP and 565 LbFt.

Have been driving it hard today and no real evidence of clutch slip in any real conditions.

I never ever drive off hard from a stop either.

I'll keep monitoring it for a while.

Thanks
