Well im not going for mega power. Im keeping the current engine for the time being which is only 380bhp.
But im hoping to get the weight well under a ton. 800kg would be nice but may be a struggle with the heavy 4wd running gear.
The car is currently 1250kg with a full interior and overly heavy GRP arches etc etc Just stripping the interior on a puma can save 100Kg easily so i think well under a ton is realistic.
With my current engine its good enough to put on a new turbo and bits and bobs to take it comfortably to 450bhp so in a car weighing say 900kg would be 500bhp per ton which would be fast.
