Hi chap's
When fitting throttle bodies, tuscan racer manifold. How have you guys plumbed in your heater matrix, that's if you still use them. I would like to keep it plumbed in.
Cheers

Hi chaps
I have an LT77 out of my tvr griffith and another out of an SD1 which I no longer need both have bellhousings and linkages, how much are they worth these days or am I better off keeping them?
Cheers

Maybe worth checking for an air leak in my opinion, ramon albon(sorry spelling) On here has a great site for the flapper system on the sd1 iirc

In my view they are better left not connected unless you live somewhere very cold.
The hot water warms the inlet charge reduces power, just my opinion of course

Hello can anyone help I need to find out where peak power occurs on a rover v8 when fitted with a 256 camshaft just as a guide for me to start mapping
Thank you in advance

Hi Chaps
Does anyone have any dimensions for the down draft manifolds like the ones that john eales sells? I could do with knowing the height just the manifolds come to, in relation to the rocker covers or head surfaceif possible, so i can look into throttle bodies which will fit under the griff ...

Hi A friend of mine had an original example as it left the factory and that had 38mm standard trumpets he changed a few things and made 350bhp without altering CC. But I guess with TVR you could have pretty much anything

Hi
If the 500 manifold is standard it will have a standard 38mm opening at the trumpet base end. If it has been ported it will be 44mm approx, the twin plenum trumpets are 42mm, so you are better off port matching a manifold to the trumpet base or have bigger trumpets fitted.

Edited to add ...

Thanks again mike for your help

Thanks again Mike that's most helpful, I am planning on running a mcleod alloy flywheel (11lbs in weight) do you think this will make the vechile less driveable with this cam?
James

Thanks Mike
Your engine sounds interesting, :D
The cam power band is stated as 4000-7400 in a 3500cc rover V8 I intend in running it in a 4500cc which may lower the curve a tad, the heads will be either JE UBV or TVR BV's, the induuction will be a twin plenum fed by (wo seperate feed pipes ...

Hi Guys
Does anyone have any experience of a rover v8 with this cam fitted, how does it drive like in your vehicle, and does anyone have any cold tappet clearence that will help with fitting it to a cold engine.
Thank You
James

Thanks Ian for some great ideas to try
The radiator is far superior to the standard, the engine in its original design had two water pumps but due to packaging problems the removed one causing said problem. My initial thought was the smaller electric pump to help when needed as it is by far the ...

Thanks Ian
Unfortunately its a gear driven pump from the crank, so not a viable option, also it revs to 8000rpm+ so cavitation could be an issue.
Back to the drawing board I guess.
