Cams
Anyone selling cams for these cars yet?
something like a 264 with a bit more lift? would go nicely with a reflash |

and you'll lose low end torque, if you care about that.

On my VW R32 with schrick 264/268 I gain torque on low end and power on top end with a tune.
Thank's to the tuning ability of VVT. it was a win win. original are something like 254 on VW R32. Let's hope it's the same on this car. |

I'd be interested to see how you'll manage to change the laws of physics. Long duration/High lift is bad for low end torque. That's one of the main reasons for variable valve lift/duration systems. And ported heads can easily hurt low end torque too, especially on a direct injected engine. You lose combustion efficiency.

Velocity and charge motion are combustion's friends. Opening up ports and longer/more valve open reduce velocity so more rpm (piston speed) is needed to match the intake velocity of the original motor.

I'm still waiting for cam options. Surely it can't be long now before we see some 290+ duration and high lift cams. I don't care about low end torque, because race car!
