just a volvo chipping amazeed at what hes just read and added this the fastist he seen was 13.5 seconds quarter mile but this gives u some idea ,, 400 bhp per tonne. Say you have 225 bhp in 500 kg car. That's the equivalent to 450 bhp in a 1000 kg car, ie 450 bhp per tonne. If you have 300 bhp in a 500 kg car, that's equivalent to 600 bhp in a 1000 kg car, ie 600 bhp per tonne. On a good turbo and engine, the RICA 304 will produce approx 300 bhp. No joke.(prity amazeing if he hes right)power to weight ratio?
