so the power results.....

Courtenay mapping achieved 305 bhp with the GM supercharger showo..

the owner is debating whether to fit a Harrop sc to get possibly 380+ bhp :wtf:
Did the owner end up fitting the Harrop or stick with the GM charger?


I believe it's now so quick he has decided to get driver training before increasing the power with a Harrop :wtf:

the car weighs less than 800Kg, so power to weight ratio is 380bhp / tonne :confused:

I can't even take in what that must feel like to drive. Lee's scared the poop out of me. I wonder what amount of G-Force is acting upon acceleration from a standing start?
