Dave, Thanks for the offer, but my chassis isnt here yet, but can you measure the engine for me, please?  overall height and height from crank centre to highest point and lowest point would help a lot. Also if you are interested in selling?

Regards

dave

Probably a bit late to be continuing with this thread but thought it may be of help. Will a crossflow fit under the Eleven bonnet, see the attached photograph.

The 1500 Midget engine is not as simple to tune and doesn't have great aftermarket parts availability like the A Series. The BMW K head is the one that they fit to the A Series and it won't go un

I will do measurements this weekend for you. If you want me to ask Westfield if they have ever fitted a x flow into a X1 I can ask when i'm there on friday. Yes I would sell it but it has had a lead free head and a rebore and acrank grind it stands me at £350 for engine and recon'd type 3 gearbox.

Spoke to Ian at Westfield today and he said he had never put a Crossflow in a 1X but recons it would be a  nice mod if it was to be done. His fear was the same as mine being the oil filler but that could be moved to the bach of the engine easily. From the crank to the top of the rocker is 13" and crank to bottom of sump was 7" on the 1300. Modifying the sump and rocker cover is easy. Hope that helps.

Just a thought...

Dry sump crossflow will be much pricier than a rebuilt A Series, surely?  Do be careful to stay in the guidelines of the DVLA major components.  Details are here:

I understand the DVLA are really tightening up in this area, and are liberally dishing out Q plates!

Indeed, a Q plate could well be an unintended consequence of fitting a crossflow, or any non Midget engine.

Hi, All,

I've just been researching next week's Monte Carlo Rally Historique and came across a page in Monte Scot's newsletter - http://www.monte.scot/pictures/Classic Updates & Monte News Sep17.pdf  (Page 5).  In it, Douglas Anderson has updated his MG Midget.  He hasn't bothered putting a BMW K series motorcycle  cylinder head on an A series block - he's put the whole bike engine in there!  The front of the engine seems to hang off a transverse bar that links the two inner wings (on rubber mounts).

It could be worth considering for an Eleven but, once again, critical dimensions will need checking, plus the support for the front bar will need to be sorted prior to going ahead.  Buy a Midget, drop in the bike engine - take photos and get the logbook updated with the new engine number, continue as normal and you should still be OK for the age related plate?

Douglas' contact details can be found in the linked magazine article but I'd leave it until the second week in February if you wished to speak to him as he will be busy with the Monte until then.

Now that's a coincidence Simon as for the past week  I've been looking in to the K1200RS conversion ( www.specialist-components.co.uk/index.php/shop/twinkam-16v-conversion/twinkam-complete-engines. ) to do when I have got mine through the IVA  that is.

I sent them an e-mail last Friday asking about how high the head is fully built up form the top of the block, but still waiting for them to get back to me, what spec did you build you engine to ?

Hi, Tony,

Mine's a fairly conventional A series.  +040" Overbore, Lightened Flywheel, Balanced Bottom End, Gas Flowed Head by Brian Slark, Trackday Cam (happy to work from 2,000rpm, pulls strongly from 3,500rpm), 33/29mm valves, 1.5:1 Roller Rockers, Weber 45DCOE on Alloy Manifold,  Megajolt Electronic Ignition.  It was measured at 106bhp at the flywheel on Neil Slark's Rolling Road and feels quick on the road - but (most importantly for me) is torquey.  I don't know how the bike engines compare with respect to torque.

Hi, Jon,

The engine was built by a good friend of mine who has known and raced with Neil Slark for many years.  Slark Race Engineering provided the head work, the cam and rolling road tune and local Oxfordshire specialists did the majority of other machine work with Trevor overseeing.  We bought the other bits and pieces from all over the place for Trevor to put together.  I was very lucky to have it done "mate's rates".
