Middy BEC changes to McSorley 442 Chassis
chunkielad - 3/2/05 at 09:56 PM

Doodled some changes to theMcSorley for a middy BEC. Anyone any ideas on problems?

So far I have thought of, Diff has had to be angled up at the front - propshaft UJs will have to work to get the drive through. Is this too much of an angle for the UJs?

No transmission tunnel means tha the driver and passenger can be closer and gives a bit more arm room. Pedals are in a narrower area of chassis but they would have more space due to tranny tunnel missing. I think that the movement of the seats centreward would accomodate the movement of the pedals.

Driver is 300mm forward of book chassis. I would also look at something other than standard style body work I think - something totally new and unique.

Diff? Why not just use a transaxle?

seen a bike engine in a GTR bit like you propose, looked ok, not sure if the engine was'nt straight onto the diff (irs) snoopy will confirm for you, can't remember, been to bed a few times since i saw it.

Fury Menace uses sierra diff with widgy prop (6" or so) to the engine.

BEC only, though and Passenger sits a little forward of the driver.

Driver has engine right next to his left ear!!

Well no one seems to be too bothered at the moment - I didn't put a transaxle in due to cost (Sierra diffs very cheap) and I don't know what one is

I definately want the driver and passenger level. My thoughts were to have the exhaust and possibly battery in the area behind the driver so as to help balanve the weight side to side (grey boxes under engine are Exhaust) it also keeps the exhaust internal so I don't have to deal with SVA issues and I can't burn my leg on it!!!

Sorry, I meant the gearbox from a FWD car, bolts up like a regular gearbox with driveshafts coming out either side. Just take engine+gearbox out of doner and 'pop' into the rear of you middy.


chunkielad - 3/2/05 at 10:47 PM

That'd be because it's a BEC - Bike Engined Car The gearbox is IN the engine.

Ah, doh! didn't see the all important 'BEC' in the post.

I'll just go get my glasses!

Better still, why not flatter Jeremy Philips (sp?) and copy his Sylva R1OT setup. Added benefit that the engine is fitted the same way as the bike (i.e. East-West)

Lad,
Nice concept, but I have a couple of minor points:

1. Eyeballing it from your sketsch, and assuming you are using 1" square tubing, I measure the engine to be roughly 7" x 10". I think this is a bit small, even for a bike engine.

2. What do you propose to do with all the space in front of the driver/passenger. Maybe move the "cabin" a wee bit forward.

3. Having driven a Mini for many years I can tell you that one gets used very quickly to having the pedals offset to the center of the car, not directly in front of the driver.

Cheers
KT

Chunky, sorry to burst your bubble, but your design has manifested itself many many times before already.
Drop in to the Middy section and browse the posts there for further info and inspiration.
Good start though.


chunkielad - 4/2/05 at 10:03 AM

I didn't want to 'copy' anyone as the thought of coming up with this myself and doing it appeals. I know that the middy section has versions of cars which are similar but do anyof them use the McSorley?

The engine definately isn't to scale. I used the McSorley plans so the chassis is. I just wanted to eyeball and get peoples thoughts on it.

If the engine is the 'right way round' in the Syla R1ot, wouldn't it then use a chain? This is something I want to avoid really as there are maintenance issues i'd rather avoid.

The driver and passenger would be further forward and hence the pedals, footwell etc would be further forward too. I did drive aCorsa once (only once) which felt like the pedals were a little accross from centre and I hated it

Thanks everyone for their info. It does seem that it won't be a problem to sort then. Myt bioggest worry was the diff being on such an angle. Would it be lubed OK still?
