would this be any good the 1/4 mile run i think it will with the lsd. but not sure on the gear ratio thanks
adam

depends on engine, gearbox and tune. I would expect it to be fine, all that could go wrong is hitting the limiter in 5th before the quater is up, but thats not likely unless you have a rather large turbo.

its only an escort rs turbo engine. its runing 210bhp do you think it will suit this engine or is there a better ratio.
adam

it will be runing a type 9 gearbox

im sure there are charts out there to link bhp/tonne figures to rough quater mile times. Id imagine that car would do roughly 10 or 11 seconds and a final speed of maybe 120 to 130. Hence, make sure you are geared to 130. You need the gear calculator program, a search should find it.

edit make that 12 seconds ish.
