A few dimensions required
Avoneer - 25/3/05 at 11:51 AM

Hi Guys,
If someone gets a minute, please can they measure the height of the tranny tunnel at the highest point (on a BEC chassis) and the distance between the fixing centres of the centre prop shaft bracket (BEC prop).
Cheers,
Pat...

Moving from the front to the back of the car, the tunnel height is 355 down to 220 then back up to about 300.

The distance between hole centres on the prop centre bearing is 150. My Indy has 30mm slotted holes on the chassis to take M12's

I hope this helps

Sorry - not got the width as well have you?

Coming up to building the tranny tunnel on my Locoblade and like the dimensions of the Mk tunnell.

Cheers,

Oh, and are those measurements from the floor up or the top of the bottom chassis bars?
Cheers,

Hi Pat why not let form follow function ?
if you are building a BEC position your engine and drive system and THEN build your trans tunnel I can see no reason why the trans tunnel in a BEC should not be reduced to the absolute minimum especially around the area that would normally cover the car gearbox lots of extra foot room to be gained ..........

Hi Iain,
Though about this and that's sort of my plan. Just wanted to get rough dimensions as I like the size of the MK one and their centre bracket mounting.
Hopefully making the tunnel lower with a curved top rather than flat as I'm going paddlel shift and want to do something different with the handbrake.
Cheers,
Pat...

Hi Pat by paddle shift do you mean electric ?
when i had the hots for a Grinnal scorpion I read about using the solinoids from starter motors to work the sequential shift on a bike engine fairly easy to set up and thenn you could just have two buttons on the steering wheel one for up shifts and one for down . I include a photo for your information.
Best wishes

Yep, I'll get the width for you later
