Mine has the LS7 clutch fitted which is rated to 600hp(ish) so mine is really at the limit. I was contemplating more mods to push power up to over 700hp but would need an LS9 clutch and at £2k, it will have to wait
The standard clutch has a fault where sometimes the pedal doesnt come back up fully when you are changing gear aggressively. It is still working, (not slipping) but Vauxhall just swapped them out for LS7 when owners experienced it. You wont find many manuals that haven't had an LS7 fitted.
The switchable Wortec is the daddy
I just need new headers to unleash the full NASCAR mental...
Mine has been wrapped, so not a standard colour
