plenum hotspot removal

[johntom]

Hi
just wondering about removing the hotspot from beneath the plenum. Is it best to simply cap off the inlet/outlet hoses or remove the minor casting under the plenum(4 bolts), if so do the bolt/water holes need pluging?

Remove the whole thing.

Plug any bolt holes that penetrate into the plenum throat with cap headed bolts and threadlock.

Its fed with coolant from the two 10ish mm coolant pipes that run from the waterpum area, tee'd via plastic tee pieces. Remove the excess plumbing and replace the perished (well, it probably is by now!!) hose with gates multifuel hose from the motor factor. 'S wot I did, and if nothing else the engine bay looks smarter.

On a TVR the hotspot is about as relevant as tits on a fish.

What is the "hot spot" ?

John you will have nothing left if you keep taking things away.
Good to see that you have got yourself down for Chatsworth, are you going to try the run on Sat before (I 've not before but hopeful for this year)

It's the throttle body heater (under the disc area) and is useful if you run a Landy or Rangy in sub-zero temps. As Ed says, just do away with the hoses and re-route. I actually left the alloy plate in place, just without the hoses connected. Either do that or remove and seal the bolt holes, otherwise the idle will go through the roof.

It was disconnected on all my cars exept for the 430 Chimp I had & the Chimp was probably the hardest revving of them all, really went like stink. So how much difference it makes I don't know. Easy to disconnect though.

's funny I drove a chim and found similar - accidentally bounced it off the rev limiter!!

If you bin the heater plate, it allows you enough room to remove the left-hand rocker cover without having to take the plenum off first.

I forgot to plug the bolt holes in mine and it just wouldn't idle, never mind through the roof...
