1275GT 8 port group 2

[tom17]

Hi ,

Here is my project for historic racing , a 1275gt group 2 ( period G2 ) with cooper's engine and weslake 8 port cylinder head.
I made a replica based on the works 8 port clubman YMO 886J ( I know it was initialy build for group 6 but can raced in group 2 with minor modifications )

All parts from the engine are original special tuning.
































I use a modified round nose mini to build my GT ( a mk5 body that will be converted to mk3 )











The engine rebuild is in progress.










I will share next steps !

What a nice Project!

Thanks,
Today I have received the left and right tank as fitted on rally car.



Normally I can use a third fuel (bag) tank to have a better autonomy like Works rally car , but I will wait to know more about the engine fuel comsuption, maybe 50 liters wil be sufficient to race today ( rallies are more shorter today ).



I have find also original repro of C-AJJ4020 wings extentions for 1275GT groupe 2 as describted on homologation form.

that looks to be an excellent project ,with some rare parts used ,keep us up to date with pictures

[tom17]

Today I have started to pre-assembling the engine , i have bought the engine dismantled as you can see on the first page.

I have checked the block and crank line , pistons clearance ( 0.0035in/0.090 mm , great !), timing and mesurate/control all the parts etc etc to prepare final assembly.

I have a question , I have see that the camshaft have two pinion , one for distributor , but the other one ?
If someone can tell me why ? ( I think it maybe for a pump ... )

hi mate
the oil pump is usually driven from the end of the camshaft what that other skew gear is for is a mystery

Finally I have find for the other gear , that's to drive oil scavenge pump for dry sump system used on sprites sebring

[mk1]

The second gear on the cam was to drive a dry sump pump. This was used commonly in single seaters, but only very rarely in the transverse models.

Sorry, I was a bit late there

thanks for your reply, all comments are welcome

[roger mcnab]

well it would be hard to run a dry sump in a mini where would one put it like the sprite has plenty of scope
well cheers roger mcnab

Didn't Mark LeMaitre's car in the late '80's early 90's run a dry sump?

[mk1]

There are quite a few examples of Minis that were dry sumped. It's just that it never became particularly common.
