After having issues with the twin plate slipping when trying to up the boost, I replaced the item with a OS Giken triple clutch, it now grips hard!!!! had to adjust the boost controller as it started to overboost on the lower setting no slip!!! new PB on the low boost setting 14 psi of 10.76@128.
Next run higher boost 18.5 psi, the car gripped,big launch , the RH driveshaft snapped, too much power, will be upgrading to Stillway driveshafts shortly. Will have to wait until next year to beat my 10.46
