BEC newbie Questions!
After being adamant I was going car engine I find myself with a R1 engine on its way in the post due to the thought of the extra acceleration and the
overall lightness of the car.
Now I have a BE on its way I have a few questions that I need help with;
1. What is the best differential gearing for a BEC?
2. How do I tell by looking at the differential what gearing it is?
3. I assume I would be best with rear disks instead of drums, in which case I think I need two master cylinders to allow me to change bias the rear
brakes. Are there any other things like this I need to think about that will be different to running a car engine 7?
Thanks in advance.

i can only answer the diff question, turn it and see how many times you have to turn the input to make the output turn once. this is the ratio.

Are you going live axle or IRS?
You don't really need disks at the back, it's such a light car - I've used Wilwoods up front and standard escort 9" drums at
the back - and it stops lovely. If you do used disks at the back you will need to 'turn them down'.
As for the diff ratio - get yourself a gear calculator spreadsheet (do a search on the archive), I would think you would need somewhere between 3.01
and 3.54.
I've installed a fiat bias valve to the rears (£15) but have not needed it. The fronts lock up b4 the rears.
I would suggest keep things simple as possible - these cars don't need to be complicated.
Other areas you will need to think about is the gear change mechanism (cable or rod) and what clocks (and senders) you're gonna use

If you want a gear calc spreadsheet.
Send me your Email address.

I'm sure I've got one, just don't know where I've put it
