Algodoo

1-6 gears,
up to accel
n and up for noz (sometimes rips the engine apart, was going to fix it but realised thats actuly realistic....)
2 tracks, on and off road, times 1/8,1/4,1/2 and full mile times
boaderline laggy, can be simfequancy can be droped a bit of need be, but dont go too low or the engine will fail, if its over laggy ill drop some of the pistons in the engine, there are far too many, 16 cylinder!
