I have asked this in a roundabout way in the track day forum with no specific answers.

As above, are they robust enough to take a bit of abuse on track/mileage beforehand?

I am considering one as a new track day project & am curious.

I know with reduction belts & pulleys, upgraded intercoolers, decent exhaust, proper inlet kit they are good for 240+, but do they last?

Even with part of the above does anyone have any direct experience of these?
