Ok, how many two-stroke racing car teams do you know of ?
Maybe Saab and their rally car...?

They use to do it on super bikes and f1 before they went inconel etc.
I’m not after an argument, it was just relating to heat etc.

What we all need are mild steel systems, they make more power and don't radiate heat as much
Takes two to argue and I'm not either....just trying to fathom now your above statement if it only applies to two-stroke motorbike works racing teams on this thread.

It’s not. Works super bike, think the might of HRC etc did, f1 teams etc.

No offence but with the raised lip all around, that looks more like a drip-tray then heat-shield. A heatshield should have more surface area to prevent the heat rising around, in front and behind that 'tray'.

I guess it does both. Its nice that it comes with the manifold as part of the kit. I think the fact its called a 'heat plate' is the give away for its intended design.
It covers the bottom of the carbs totally, which is about as good as you can do.

No it's not at all !
There are many ways to be better and the most straight-forward one is to protect not only the carbs but the intake manifold through which the fuel passes before the engine.

Thats disappointing given the price.

Hardly, as it gives everyone the choice - you prefer this :
https://datsunspirit.com/shop/heat-shield-version-iii-for-dsi-itb-setup/
https://datsunspirit.com/shop/ver-ii-heat-shield-webers-itbs/
others do otherwise and a roll of D.Tweeks Nimbus is a lot cheaper !
Is this 'worth' $4500 ? https://datsunspirit.com/shop/hand-...-stainless-steel-header-with-merge-collector/
It was conceived for a specific purpose which it no doubt does very well but will it work for all set-ups and uses ? No.
Horses for courses...

I've known much smarter Z engineers than I install full heat-shields....and then cold-air intakes....so that it can be reheated before combustion ?

Sean, it is disappointing given the high price asked. Just because you can spend even more money(not a bit of bent alloy sheet is worth £150).

Good, because I'm tired of debating with someone who's always right and besides, it never gets THAT hot on your soon-to-be tax-haven island.

Considering the amount of data, references and photos I've given you over the years, and the amount of direct questions you've asked me over the years, I reckon this "your guru" nonsense might very well apply to you too.
Jealous?
Well that settles it then.

Cheers dude, simple but effective!
I'm begining to think that a small and simple heatshield will do an adequate job on the basis on what's been tried and tested without going mad with full sheets of insulation.
What seems to be of most benifit would be running some kind of cold air induction box in tandem like the one Richie has just finished.
There's always the next modification!
