dont have spray and anyway it wouldnt cool the intake manifold which need to be as cool as possible why cool your air with a great big front/top mount/spray then send it to a red hot intake manifold...pointless

[QUOTE=swisstonihasher;7999871]Na m8, you not follow proper like, I've got intercooler water spray (external) which might help a little to cool induction but also water injection (internal) which def does cool induction and will also cool the inlet manifold as the whole charge and some of the surroundings are cooled during water evap.[/QUOTE
Ok but you said spray not water injection

Check me words, says "water injection - just up the spray" its right as its still spraying inside...anyway dont matter...
Wonder what the manifold spacers will do temp wise to induction, real hard to prove any drop that near to combustion area.

Yep,the colder the better! Im making my own at the mo,have also made some header tank spacers to stop the heat transfering to that side of the inlet manifold. Im also going to take the throttle body coolant pipes off and join them together,as this stops the hot water heating up the intake gasses as they pass through the throttle body. Total cost? £15! (and a bit of time!)

You is best get bigger intercooler at end of day if big power as inlet manifold spacers just stopping heat from engine core to inlet...this heat is still somewhere but not on induction, better to have it reduced in some way, spacers dont do that, water injection or FMIC helps.

Been on the sher---berts but yep, def disconnect the de-icer hosing from the inlet manifold - I did that ages ago, no probs but cant afford to run in winter plus she mad enough in dry weather let alone snow.

I did extensive testing with insulating materials some years back; a phenolic grade insulator was found to prevent the onset of heat soak longer than the equivalent thickness tufnol and had suffered less creep.

Im using 10mm tufnol,got a 300mmx300mmx10mm sheet online for £15 delivered. There's enough to make two sets,so if i mess one up,theres loads left. I've just got myself an abro file,which will make things easier,also have a dremel to 'fine tune' the finish,when i get round to it!

How does making the phenolic insulator thinner, avoid having to use OEM gaskets to seal - unless they were never needed in the first place with the thicker gaskets made by Carl?
