Wär schon interessant.
Aber ein ordentliches Gebläse ist wichtig, hab erst unlängst einen sehr kritischen Text über die Prüfstandsläufe gelesen.

Hier der Link von Brodie-Britain:

And a word of of warning, stay off power testing on rolling roads! No fan (other than a wind tunnel fan) has the ability to cool the air through the intercooler. Put your hand out of a car window at 100 MPH and see if you can find a fan that has the same effect. We have been advising our customers since the mid '80s (Cosworth days) to stay off power testing on rolling roads. They do more damage than you can believe, since it's impossible to keep the inlet charge temperature at a safe level! We have seen countless damaged engines all down to reckless power testing on the rolling roads! You have been warned!

So guy's and girls (we know of one racy Cooper S chick near Dundee!) there you have it, remember its our philosophy at BBR"if its OK, don't change it" look between all the BS guys, its your hard earned money!

Note for Cooper S pre 2005 model owners with supercharger pulley reductions:
We have noticed without exception due to the extreme heat induced on so called "power runs" on rolling roads, Cooper S owners are over heating the coat applied to the rotors within their earlier type Eaton supercharger unit. This causes delaminating and flaking away of the Eaton rotor coating, a loss of efficiency within the supercharger (loss of seal) therefore reducing boost pressure and airflow! This will cause a loss in power, but more importantly the delaminated coating has nowhere to go other than into your intercooler (further restricting air flow!) or even worse with smaller parts straight through into your engine!

Ja wolfi ich mach das eigentlich für euch ich hab solche Berichte schon vor glaub 1 1/2jahren gepostet vor allem im technikforum nur in deutsch ich bin nicht Prüfstandgeil aber ich hab mal gefragt.
