impossible to say. you just need to try it out at various revs etc. too many variables. tyres, suspension, diff, as well as engine spec etc all change things totaly.

go find some deserted industrial estate, and do launch after launch at various revs, gears blah blah till u get it right, the only way youl know.

esp with launch control youl build up boost the longer your bouncing off the limiter too, so thats another thing to try out. with L/C you should easy get 1bar boost+ after a few seconds on it, and then a 2nd gear side step clutch launch is deffo on the cards, even then it might spin too much, need to try it to find out.

what engine you got anyhow? peak power at 4300 is like a bloody turbo diesel
