Just got back from the TDi’s dyno and Steve L’s car made an extra 29bhp at the hubs with the Whifbitz 280 cams, thats around 33bhp at the flywheel approx. So pretty happy with that. Unfortunately TDi’s hardrive fried last Friday so they lost the dyno plot I had with the HKS cams fitted.
So all we know is that it makes more bhp, 629.4 at the hubs which is about 723bhp at the flywheel. Thats good enough for me, they work and better than the HKS offering.
