MED DRY DECK ADAPTERS & PIPE

Description
Part of our dry deck kit supplied individually.
The kit consists of the following parts;
- 2x aluminium adapters
- 1x silicone hose
- 4x Allen cap bolts
- 2x hose clips
The engine outlet fitting will require a small cut-out to fit around the engine steady fixing, to be machined after drilling and tapping of the block.
Frequently Asked Questions
Why would you dry-deck an A-Series engine?

'Dry decking' refers to the process of blocking some or all of the coolant transfer ports between the cylinder head and block, re-directing coolant flow to more evenly maintain temperatures across the engine. On a competition Mini engine, we find that cylinder number four, furthest from the water pump, tends to suffer from excess heat build up. Dry decking re-routes the coolant flow along the block, out of the engine via a 180-degree hose and back through the cylinder head.
How do you dry-deck an A-Series engine?

There are a few different ways to complete this conversion. Either modify the cylinder head with brass bungs to restrict flow of coolant, modify the block, or use a special steel-shim gasket, with the waterways blocked off. The end core plug will need to be removed and this face drilled and tapped for the supplied hose take-off. On the cylinder head, the end will need to be spot faced and drilled to suit the second take-off. The supplied screws are M5, standard 0.8mm pitch.
Will this suit all A-Series engines?

We would usually recommend this for Mini/Metro applications only, as the Sprite bell housing can hinder access. It's most effective on high performance or competition engines that generate excess heat, or those driven hard in warmer climates.
How does the hose take-off adapter fit around the top engine steady?

Once the adapter position is decided upon, you will need to file a notch in the block adapter for clearance of the engine steady bracket.
Where does the hose fit exactly?

We would suggest to use the front-most core plug, obviously on the clutch side of the engine. On the cylinder head, typically this works better placed centrally on the side face. The end will need to be drilled and spot faced, as above.
