Hi all, what's the easiest way to find out the diff ratio of my live axle??

May have a change of plan on my engine conversion, just bought a c20xe now thing of a bec as I have experience of bike engines.

Issue I have is that my car is about 650kg with a crossflow and type 9, so my bec will weigh around 550kg!! would this be too heavy and still to my original cec??

Thanks

Julian

Can you not just count the number of turns of the input shaft for 1 revolution of the output shaft?

Ed.

true that will give me a rough idea be better if I knew the different ratios of a standard the live axle..so I can gauge it better.

There's normally a metal tag on the back that says the number I think, there was on mine.

550kg with a bike engine is fine!! Not sure it'd make that much difference though.

Bike engine is 60kg (ish?).
Is a Crossflow and type 9 really 160kg?

Seems heavy for a crossflow engined car.

My Indy + Pinto weighed ~600kg

Have you had it weighed on a weighbridge to confirm?
