Julian H Posted April 19 Share Posted April 19 Hi I have a piece of insulation with a foil face wire tied around my starter to protect it from the exhaust heat. It has deteriorated quite a bit over the years so would like to replace it with something, the same preferably. What is this product please? The insulation is about 10mm thick and made of a very dense Rockwool type product, with the foil on the outside? Thanks, Julian Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 19 Member Share Posted April 19 Please could you add a photo. Jonathan PS: I'd rather have a shield that's spaced off the starter. Link to comment Share on other sites More sharing options...
Julian H Posted April 19 Author Share Posted April 19 Hey JK 👍 I guess mine is spaced off the starter, by 10mm insulation LOL That is what I like about it too! Julian Link to comment Share on other sites More sharing options...
Julian H Posted April 19 Author Share Posted April 19 Insulation around the starter that has seen better days! Link to comment Share on other sites More sharing options...
PlastererPete Posted April 19 Share Posted April 19 “DEI”do heatshield blankets for starter motors (available from Demon Tweeks) as do “Funk Motorsport”. Both priced around the same. They look thinner than the one you have but are probably a better grade of materials. 1 Link to comment Share on other sites More sharing options...
Julian H Posted April 20 Author Share Posted April 20 Hello Pete I saw that thanks. I will probably go for it if I can’t find the insulation backed type. Cheers, Julian Link to comment Share on other sites More sharing options...
JP Posted April 20 Share Posted April 20 @PlastererPete - thanks for suggestion of a heat shield - I've been thinking of one myself. The DEI looks simple enough to fit. Is it a case of cut to fit with a velcro closure? My primaries will make fitting anything else a real faff... Link to comment Share on other sites More sharing options...
PlastererPete Posted April 20 Share Posted April 20 @JP I haven’t got one myself as my primaries are on the opposite side. I have got DEI exhaust sleeves and Funk Motorsport cable heat shields. The cable shields are just cut to length things so I assume the starter motor shield would be a similar thing. 1 Link to comment Share on other sites More sharing options...
7 wonders of the world Posted April 20 Share Posted April 20 bear in mind that this material conducts electricity and it not secured it can and does vibrate free and cause a short - I would look at a proper heat shield 1 Link to comment Share on other sites More sharing options...
john milner Posted April 22 Share Posted April 22 Some exhaust wrap for a few inches to a foot around the primaries may also help with reducing heat to the starter. Link to comment Share on other sites More sharing options...
JP Posted April 22 Share Posted April 22 That might be a better idea. Any particular brand of tape to recommend? I've seen DEI tape available on DT website in 15' or 50' rolls. Roughly how much does one need to wrap 4 primaries? Link to comment Share on other sites More sharing options...
Guy Lowe Posted April 22 Share Posted April 22 (edited) I gave up with wrapping the primaries as they starting rusting (stainless 🙄) have now made a shield with Nimbus double layer from Merlin Motorsport p.s. Image taken when primaries removed. Edited April 22 by Guy Lowe 1 Link to comment Share on other sites More sharing options...
Ainsley Posted April 23 Share Posted April 23 Rusting ! That's not good, is that because the wrapping held moisture and that caused the rusting ? I'm curious as I'm planning on wrapping my pipes. Don't they get so hot any moisture is evaporated very quickly ? Link to comment Share on other sites More sharing options...
TomB Posted April 23 Share Posted April 23 That Nimbus product is really neat, I like that. 1 Link to comment Share on other sites More sharing options...

Are you thinking of a bit of angled sheet bolted to the block and acting as a barrier between the starter motor and the exhaust but leaving the starter motor fully exposed?

Not really sure on either question, my primaries are Cheesman so good quality stainless steel. I had them wrapped from new for about 4 years when a fellow owner (Phil Waters) warned me about the problem he had, so I removed the wrap and there was definitely signs of rust and they were very badly pitted. Took a fair bit of aggressive polishing to clean them up. Link to comment Share on other sites More sharing options...
JP Posted April 23 Share Posted April 23 Wow, my primaries are from Powerspeed c.2002 and seem fine and that's after 14 years of no use being stored in a draughty barn...but with no wrap... Link to comment Share on other sites More sharing options...

Mine have been fine since I removed the wrap 😃 1 Link to comment Share on other sites More sharing options...
Nigel Riches Posted April 25 Share Posted April 25 Nice tin bashing here Guy, I saw your post on the other page we use, and I have a sheet of this stuff in the shed, especially as the starter has started to emit a strange noise on cranking, possibly too late now, more fun and games, I seem to spend more time mucking about sorting things than driving it. Cheers. Nigel. 1 Link to comment Share on other sites More sharing options...

Hi Nigel, It’s really easy to bend, I just rolled it round a large bottle on my bench and you can cut it with a good pair of scissors or tin snips. 1 Link to comment Share on other sites More sharing options...
