Hi all, I'm after some advice on what to do with my engine. I've already fitted the AMR300 supercharger (brackets & pipework) and the lump is at the mechanics getting striped. The head has been upgraded to 998 cooper spec and converted to unleaded, the rest is stock. I'll only be running a low boost due to the small SC. The engine befour the upgraded head did 30.9BHP (big I know
) so with the SC I think around 50BHP just a guestamate.
Will a standard spec diff & box do that power with no problems or should I look at 1098 or 1275 parts?
Also any susjestion on clutch and flywheel?
I don't want to rebour it if I don't
have to, is it worth getting some low comp pistons?
What would be a good cam and is it worth changing from std?
Would one of those pulsar dizzy's be a good idea?
I asume it's a 3.44 diff, it has pot joint CV's and a rod change box (2 rods from box to stick) I use the car as a daily drive and I want to do 110km with out it screaming in pain but still be good at low revs, I don't want to rev over 4500-5000.
Any susjestions would be appricated.
a standard gearbox should be fine, but an uprated clutch is probably a good idea.
if you run low boost, you can run standard pistons, but make sure the motor is healthy and not blowing past the rings or anything.
you suggest you dont want to rev the motor and you say its a daily driver., So a standard cam would be my first suggestion, a sw5 might be another option, theres a bloke using one with his supercharged smallblock here in adelaide.
my re-13T equipped mini doesnt get going until 3000rpm and has a lumpy idle.
a pulsar dizzy is a bad idea, it will not suit your engine without a lot of modifications.
I am running standard points no worries., but i will upgrade to a petronix or similar at some stage. Dont forget to have your car dyno tuned including ignition.
i'd guess at 60-70hp at the wheels.
