am I the only one that think's the first cossie doesn't sound good
Sounds like it's got a screamer pipe? which I hate the sound of
HKS SSQV "BOV" - facking hate them too!
What is it actually revving too? sorry if I missed it in the thread.
I've known a cossie with hydraulic lifters to rev to 8500 and occasionally the lifters would pump up, so i'd definately say solid's are the way to go over 7800ish
