CAMSHAFT SELECTION AND A BIT MORE
Discussion
This is the John Eales developments manifold for Webers or TBs.
It's actually the resin cast but the real ones are about a couple of weeks away.
If you want any more info let me know and I'll put you in touch.
It allows TBs to be put under a TVR bonnet which a vertical setup (like mine) is hard to do.

He was saying around £600 when I last spoke to him but it all depended on casting costs etc.
It doesn't need a separate thermostat housing and a couple of other bits which keeps the overall cost down.
It also means not having to cut a hole in the bonnet and so on.

£600 Plus how much roughly for throttle bodies, airboxes, filters etc.? Inquiring minds... (although I have a feeling I don't want to know the answer, really...

)probably a lot, but if it really works well and you want an edge over the competition surely it'll be good value

You can run 14 cux if you resort to boxing the trumpets back in via a plenum etc but whats the point of that?
Feeding the trumpets from a plenum doesn't seem like such a controversial idea, how else are you going to feed them with cold filtered air unless you stick them out through the bonnet? TVR do it and that seems to work OK? You'd need to pay attention to the restriction, but if you can engineer throttles into a trumpet base surely it's not asking much to stick a box over the top and pipe it out to the front.
Whether it would be sensible is another matter, I can't see any good reason to keep the CUX if you're making mods that are this dramatic. Surely you'd want to get rid of the AFM restriction, and get mapped ignition etc.
Hi pete
I am sure we are on the same wavelength here!!
All i am trying to say in response to the pics of the trumpet base with the throttles in them earlier in the post is what is the point of putting the throttles there only to go and put the plenum back on? why not just leave it as it was?

You could do this for a lot less, you are going to have to use airboxes on these if being fitted into a tvr due to the exhaust being directly under them, now if it was me fitting this manifold i would not bother with throttle bodies and just fit trumpets into the manifold, make a nice air box out of carbon and put a 75mm ish throttle body on either side facing forward!
It certainly is worth a rebounce and in particular with respect to the JE manifold / throttle body arrangement. I have only a limited understanding of what is seemingly a rather complex issue, however Rob’s comments had also crossed my mind when looking at it. I thought that one of the problems with a plenum, particularly when running a cam with significant overlap is exhaust gas from one cylinder contaminating the next one to breath in. With throttle bodies they should only contaminate themselves not their neighbour. However if you put a set of throttle bodies on and then stick an air box over them it seems you have to some degree the same problem. I suppose the contamination is limited on a light throttle by the throttle itself and also in this case you now have two sets of four rather than eight.
Other than the charge contamination issue what are the benefits of using individual throttle bodies ?

I would luuuuv this manifold on TBs combined with an Emerald,DTA,Megasquirt etc,oh how the RV8 would show you gratitude It's actually the resin cast but the real ones are about a couple of weeks away.

then i could go completely "Ye Ah" with the cam profile and some cowl induction/ram air

Yep it's definitely the future imho It's actually the resin cast but the real ones are about a couple of weeks away.

I would think you only need tb's when you have very lairy heads and cams ..
Whilst the ACT triple plenum is good the ultimate restriction will always be the std rover manifold which narrows to somewhere in the region of 38mm on each.. so that will restrict the ultimate power/torque.
Too big a TB will will the motors driveability.
