Thought it time I finished a design I started 4 years ago.......
Turbo Mini Forums

Almost to the month back in 2005 I started this - then stopped in Jan 2006 when I got into the K conversion - so I've pressed on in the past few weeks to get it together.

hope the lines don't make your eyes go funny.lol!

If Carling made Mini engines
it would probably be like this one!

wheres the heater take off?

there is an additional piece which bolts to that side of the head to complete the water circuit - you can see some recessed machining at that end in the pic ready to accept it.

Whats the stud pattern on the inlets?

Paul

I seriously doubt it!

Paul, what I wanted to do with my design was to keep the inlet tracts as straight as possible, this isn't as easy as it sounds when you start looking at packing throttle bodies into the spacing that two inlets close together require. The stud pattern is to suit "single" throttle bodies which I can make fit this spacing, the other option I'll probably take into account look is bolt on stubs for M/C carbs. You can't see in that shot but the inlets are down draught to a good degree to increase the length of the short turn radius.

I presume this'll be ally John?

not tempted to machine a cam carrier to fit on top of it LOL

Hi Joe - yes ally - billet as usual from me.lol!

I don't know if my mind can take that many cross configurations,hehe

LOL,

I like that the ports are closer together than on mine, it will make plenum building much easier, IIRC the centres on mine were around 95mm for the outer ports (as per a weber naturally) and approx 110mm between the centre two, that couples to the 40mm hole at the port face means you end up with a massive plenum (circa 2.2litres iirc).

if i was you John I would (at least at first anyway) make the head so std bmw throttles would bolt straight on, as yu have the stubs already, and the plenums.

Joe - port spacing is 66mm for the end pairings!

thats significantly better, i guess probably about 85mm between the middle two, thats getting on for a third less than mine for the total length,

can i see injector holes on the head too?

also have you seen the pics of cut up elder 7&8 port heads?

yip those are injector holes facing the back of the inlet valves

not sure I've seen the inside of those heads - seen them from the outside

A couple of pics with less lines.
