From what Roy has said im pretty sure his has seen 8500 on numerous occasions!
And its not like his motor is lightly tuned either.
BUt prob wait till he comes in and drops his 2c
But i feel the same as well as you guys... I remember going to Launch my car once and i forgot to put it in gear :S
I dont know what it revved to but it did make a odd noise, like not something breaking and not flutter and not my BOV... Motor still seems A-OK though!
