Talk Morgan Forums Morgan Sports Cars Morgan Photo Gallery NEW 1600 CVH Intake

Been thinking about the new carb and induction set up on the race car for for some months.... The CVH sits slightly further forward than the cross flow or TR engine and the front carbs using DCOE's are shrouded by the inner bay pannel (inner wheelarch).

I wanted a positive pressure manifold with minimal losses and ideally must out-perform an open to atmosphere (ie. just trumpets with no filtration). But with must use a filter for longevity and require no alternation to the bonnet or ideally the visible part of the wing.

Having come up with a few sketches at home and A LOT of measuring, the parts all arrived over the last few weeks and....

Over the last few weekends and all this weekend we've finally developed a new intake for the 4/4 CVH. I've not seen this on any other Morgan before and has been developed following the concept found on the Aero 8.

It should provide performance beyond that of bare trumpets & carbs due to the ram effect of the intake.

Yes... the Airbox can take another 15mm Ram pipe length (45mm max) so I went for the 30mm versions to give plenty of space.


Not yet, still waiting for the electronic ignition system. It is booked to be set-up on the 14th. (all bieng well)



Interestingly the advice from the Rolling Road company is that it will be extremely difficult to mimic the full ram effect without actually driving, therefore will set-up without the air-box and supply 1 step larger Jet if we find it leans up at high speed.... might possibly try to direct their high speed fan and run at the end of set-up with the inlet fitted??? (Not really ideal though)



Unknown.. and possibly might not get to find out... that said the shrouding of the front two cylinders means running without an airbox with no other modification would certainly be worse. The clearance to the intter bay pannel was 20mm from the end of the carb with no trumpet at all!




Let you know what figures I get.. might even post the graphs as I have before.. also keen to get a revised weight to calculate Power to weight.
