I vintage race a 2.0L six single plug narrow body 914, and for years used a Patrick Motorsport “901” style flywheel and Centerforce 215mm clutch package. I would like to go to their 5.5” clutch and ultralight flywheel, and I understand all the advantages, but I don’t know if that’s offset by lurching around the paddock and in and out of my trailer, and shorter clutch life. Will I forget about that on the track?
Thanks for the advice, Gavin |

Learn to drive it correctly and you will be fine. If you get the proper equipment you will have no slippage as Andy is saying...this car runs a 7.25" triple and is rated for 1,200 horsepower.

QUOTE(Cracker @ Oct 13 2021, 11:00 PM)  ...this car runs a 7.25" triple and is rated for 1,200 horsepower. That is an absolute beauty of work. But I hope it's a project in progress, as that's not NEAR enough rollcage for that application. Smaller/lighter clutches for lower rotational momentum (faster acceleration) versus sufficient clamping force (for no slipping). Pick your compromise. I'd suggest leaning toward the latter. We're not F1 here, and we're not going to win any money and chicks and job opportunities doing this. And dealing with a slipping clutch on race weekends sucks. |
