I've recounted the story before of my wife's mildly tuned 1098 minor exploding a riley 1.5 diff and destroying the axle casing with shrapnel necessitating a replacement axle :o you have been advised :D

I'm not particularly gentle with it and haven't busted anything yet.


The operative word here is "yet".

Whilst this can be discussed till the cows come home all I can say taking the above comments on board is that I must be very lucky with my Minor axle as it has withstood hundreds of full power standing starts so I will not be rushing out to change it for an alternative axle.
Having the right components and build quality does help.
Here is me and my Minor leaving the start line at Gurston Down Speed Hill climb under full (135 + bhp 1380cc 'A' Series) power and not a broken half-shaft or busted diff in sight. :D
I do believe that is smoke coming off the rear tires. lovely jubly.

Hi Phil.

Is it totally stock or do you have hardened half-shafts?

No - Hardly anything is stock on my Minor 8)
Many years ago I managed to get a pair of brand new Minor half-shafts and had them heat treated so that they would transmit a guaranteed 178bhp.
They have never let me down. I do have a spare pair on the shelf just in case but have never needed them.
Those are very sticky 7.00" slicks on the rear (and on the front too).

Not turbo charged so no intercooler - it is normally aspirated through twin 45DCOE Weber carburettors using all 4 chokes feeding through the 7 port Manx Racing 940 head.
There is a photo of Bill Quine who was a ex Downton employee and owned Manx Racing and who did the head, a photo of a similar 7 port head / combustion chamber one inlet manifold fitted and the other manifold with 45 DCOE fitted in the link below.

Gives me a bit of confidence. I've also got heat-treated half-shafts.

Not the 178bhp unfortunately:)

It does sound well - more like having a supercharger fitted but the noise is mainly made by the C/R straight cut gears in the Quaife box.

Phil is that a type 9 Style quaife box that would fit my supercharged V6 8) My good friend on here with the lotus pickup has a sequential 6 speed quaife box it sounds like a full blown race car on the road ! It's mad ! But I love the sound ! :lol:

No
The reason it has not been dry decked is that unlike the Mini the rear of the block is covered by the bell housing and also there is no room between the rear of the block/head and the cross member to fit the adapters. Within the rules I am not allowed to cut the cross member.
Notwithstanding the lack of dry decking the water is positively circulated by an electric water pump made by the Australian firm Davis Craig with additional electronic temp control.

The gearbox is a Quaife 4 speed Clubman box derived from a Ford RS200
