Does anyone know the difference in gee gee's between the two on a J spec tt auto? I got 290 at the wheels and only 345 at the fly, but he said he estimated the fly!!!!

 

Jase :cool:

Fly is always an estimate.

 

I think its approx 15% for a manual and 20% for the Auto

 

(Thats a percentage loss from flywheel to wheels.)

Jase 290 at the wheels is aprox 360 ish IIRC, mine did 290.5 and it worked out being 363 fly :cool:

Someone did have a conversion on here some where, no doubt it will appear shortly ;)
