While the roll cage fab and covid really delayed things, we've been testing and racing for the last six months. The NC has been a fantastic car for us. We've had four starts (two at VIR North, two at NCM), four FTDs, two wins and one second place finish. We might've had three wins if we hadn't of shown up to VIR with no crew, just me and my co-driver (0/10 do not recommend).
We'll be at CMP with it in two weeks, then PBIR, then Sebring. Next year we're really hoping to run in the SCCA's national enduro series.
The car is about 1950 lbs full of gas, and makes 167whp. Stock motor, we ported the intake (removed the butterflies), 1.8" GWR header, custom ram-air intake, and my tuning. 255 tires on 17x10s. We've tested a few different compounds and so far our favorite are Cooper RS3-Rs.
We also tested 225/45-17s on the stock wheels at Daytona, and oddly found them to be barely any faster in the straights. We repeated the same test at the Firm and got the same result. Baffled me, but the data doesn't lie? At the Firm the 17x10s were worth 0.65 seconds, though with different compounds (255 V730s vs. 225 RT660s). I thought the RT660s handled the heat better.
The only failure we've had was a fuel pump (the original one from 2009) at VIR. The car started to lean out to 16:1 AFRs. Remarkably the car lasted for hours like this and took the win, with no signs of engine damage. We still haven't even popped the valve cover off.
We were going to run GP1 in WRL, but they changed ownership a while back and no longer allow cars without windshields. We tested a makeshift windshield with no roof at Daytona and it was awful, lost 7 mph! I think we'd need a factory-shaped windshield + hardtop to make it work.
Could a mod move this thread to the endurance section? Thanks!
