The limit is there because over 8000rpm you need solid lifters. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft" Peugeot 306 GTi-6 2000 (X), Moonstone

But in turn your going to over spin the charger by 25% 126,339rpm if you Rev the engine too 8.200 ________________________________________ Me

I am using the same rev limit on the current engine and setup but with a bigger charger and that makes 454bhp restricted. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft" Peugeot 306 GTi-6 2000 (X), Moonstone

Any box issues ? I’d like to make the 400 it’s claimed but if I Rev to 7.800 it won’t make that and I don’t want to over spin the charger much there not a cheap thing to fix ________________________________________ Me

I've had the box internals strengthened and to be honest I'm very mechanically sympathetic with it. Traction wise, it's fine, don't have any bother at all. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft" Peugeot 306 GTi-6 2000 (X), Moonstone
