My car is 3240lb (1472.73kg) race weight and is not stripped out one little bit as more than a few people will attest to. It is a street car and gets driven over an hour to WSID on the tyres it races on, raced, then driven over an hour home.
As a matter of fact, 119mph, 265kW and 3240lb go together quite well in the drag racing maths world. Look up "Moroso HP Calculator" or "Moroso Slide Rule" for more info.
You CAN just attach a boost controller to a 33 or 34 and set it to 15psi. You can mate, simple.
