Legalities with engine conversions?

[brett_celicacoupe]

but this part of the argument came from D-Master's engineer wanting to calculate theoretical top speed so as to work out brake size required... so its more a bagging on the SA engineer than an argument as to why you need to increase brake size.

bzzzzt not quite

TSA will want a brake fade test done $375

I can then calculate a theoretical top speed to determine the tyre speed rating needed.

enough bagging out 18RC's

my 18RC is capable of pushing the RA40 up to 190 (on private roads)

Uphill is a different story, but you have gravity to aid your decelleration then. So I dont know just how valid your argument is.

With a sufficient power:weight ratio, uphill or downhill doesn't make a lot of difference. Let me know next time you're in Brisbane, I'd be more than happy to demonstrate this point.

even with a reasonable p:w.. I'm pretty sure my old ma61 would have been limited by revs/gearing only - at 220 it was still pulling like a train at any rate (private track etc)

never mind him, he owns a 16R ra40 LB.

uphill matters!!!
