need4speed Posted February 20, 2017 Share Posted February 20, 2017 Removed the trumpet base to turn it around and was wondering if it can be reused? Save me 15 quid.. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 20, 2017 Share Posted February 20, 2017 There's a gasket....? I thought it was just blue hylomar? Unless I am thinking of the wrong bit.... 1 Quote Link to comment Share on other sites More sharing options...
need4speed Posted February 20, 2017 Author Share Posted February 20, 2017 Maybe it's a mod to try and keep heat of induction air down? It's a gasket that fits between inlet manifold and trumpet base. Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted February 20, 2017 Share Posted February 20, 2017 Looks like one of these : http://www.sc-power.co.uk/pages/sc-power-plenum-spacers.html (Scroll down) Do you have the other plenum spacer? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 20, 2017 Share Posted February 20, 2017 P.s. can't imagine it making much difference... Not in a LR Quote Link to comment Share on other sites More sharing options...
need4speed Posted February 20, 2017 Author Share Posted February 20, 2017 No just the thermal gasket. Not the spacer Quote Link to comment Share on other sites More sharing options...
paintman Posted February 20, 2017 Share Posted February 20, 2017 (edited) Can't find that gasket on LRCat. Didn't find a gasket or spacer on mine (1986 EFi) when I had the ram housing off & the LR manual that covers mine (It's the big book, not the RAVE which doesn't cover mine) just says to use Hylomar between the housing & the inlet manifold. So I'm assuming it's a mod for some reason or other - I've seen articles where shortening the trumpets is supposed to do something so perhaps this is in a similar vein?

Bowie69 Posted February 20, 2017 Share Posted February 20, 2017 Yeah I am sure it's aftermarket also, half of that kit I posted above. Hylomar both sides if you want to re use it, if not just omit, and use hylomar. There's nothing I can think of that would mean you would need to space it by that small an amount.

paintman Posted February 20, 2017 Share Posted February 20, 2017 (edited) Bit more on shortening trumpets & also mentions the insulating plate you have. http://www.g33.co.uk/tuning.htm (Ginetta G33) "The Range Rover inlet manifold throttle body has a hot water preheat fed from the water pump. Although you might need this in sub zero temperatures, its really not needed in the G33. At low temperatures the manifold is heated to prevent fuel condensing in the inlet tract, but it also has the adverse effect of heating the air and reducing its density. You may have noticed the car performing well on cold damp morning, and the colder air is the reason for this. The simplest thing to do is simply disconnect the two pipes that provide the preheat just under the butterfly valve in the Plenum chamber. The pipe can then simply be looped between the water pump and inlet manifold take off points. Another modification involves fitting a thermally insulating plate between the inlet manifold and the trumpet base and are commercially available form some V8 tuners for around £50. This prevents the heat from the engine traveling up into the plenum chamber, and I have seen figures quoted of an extra 10 BHP when the engine is hot. There is a problem with the G33, that the insulation plates raise the plenum chamber by up to 10mm, and this means it wont fit under the bonnet ! The aftermarket plates are made of Tufnell. Blank sheets available on Ebay for a few pounds." The websites I've looked at which talk about trumpet shortening advise taking the same amount off each trumpet so the relative difference in lengths are maintained. ETA. Link talks about Tufnell, appears to be a spelling error & should be Tufnol Edited February 20, 2017 by paintman Quote Link to comment Share on other sites More sharing options...

elbekko Posted February 21, 2017 Share Posted February 21, 2017 The later Bosch engines also have a gasket between upper and lower plenum. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 21, 2017 Share Posted February 21, 2017 I very much doubt that any of that makes a noticeable difference, except to the pocket of the chap selling a gasket for £50 Quote Link to comment Share on other sites More sharing options...
need4speed Posted February 21, 2017 Author Share Posted February 21, 2017 £50? It cost me £15 including postage Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 22, 2017 Share Posted February 22, 2017 That's £15 more than I've spent and I can't say I'm suffering terribly from a lack of power then again I just never plumbed in the plenum heater so I' guess I'm getting the awesome power boost from that Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 22, 2017 Share Posted February 22, 2017 Was that £15 for the whole hotwire setup? Quote Link to comment Share on other sites More sharing options...
