HP4 Flywheels

Hi all

Any news on these flywheels? horror stories etc? good points?

Like to hear your comments

Good points are:
They increase power sometimes as much as 1bhp+
They sound fantastic

Bad points are:
They increase clutch wear and can cause clutch problems
They don’t cool as well as std flywheels
Can make peaky motors even more peaky
Can fall to bits
Have been known to cause timing problems.

My advice is to either lighten your own flywheel or fit a pk one[:rotate:]

yes, Diablo made a very good profile of them. Nothing more need to be add.

Just one more thing for you Fairlie, the lights are not so bright with the hp4 either

Ok Lads Thanx
