C3 Hood Insulation or 'Go Naked'

[Adtheman]

Hi There. I have to renew my hood insulation for my '75 as its torn, tatty & hanging. does anyone know of any nice hood liners with a logo maybe, ive seen some super nice ones on C5,6&7 variants but not on the 3. i'm kinda loathed to spend £50 on a piece of shaped loft insulation as thats exactly what it looks like.
I've read various things about removing and going naked, some say not a problem others say it has effect on paint blistering. My feeling is its there for a reason.
Any suggestions?

I understood it was originally put there to reduce engine sound, not heat.
Mine was tatty so removed years ago with no effect on hood paint to date.

Thanks, Why ever would you want to reduce engine noise ???? Peasants

Premumably to reduce mechanical noise - like tappet noise and a big end or two knocking?

Exactly.
Someone has been known to drive around completely "hoodless" in public???? Not sure thats legal.

Perfectly legal I'm sure IF one makes sure any 'rotating' parts are covered so small children and stupid people can't stick their fingers, other body parts, appendages or stange objects in to and injure themselves.......

That could be tempting especially when I get my DeWitts Rad and electric cooling fans installed later this month. Seeems a lot of money to keep it hidden lol

ouch I think I’ll go naked for a while

It's an interesting distraction when driving (hard) watching the engine's torque reaction........

I reckon a hood could get hotter from the sun beating down on it on a summers day than it ever might from engine bay heat rising, especially dark colour paintwork?

I didn't fancy spending £50 for a bit of insulation, so I spent £20 for some self adhesive 6mm acoustic foam instead. Looks better to me, just hope the glue doesn't let go when it gets hot!

That's really neat, but dude who nicked your interior

I went down a similar route and used self adhesive foil faced heat resistant insulation rather than pay silly money for a custom made job . Bought it my the metre off a role from Earls at Silverstone Performance Parts at Circuit . Can`t remember how much I paid and cannot find the invoice which is odd as keep everything spent on the car . It wasn`t cheap as chips but not overly expensive as I only bought enough to do the job . I made a cardboard template first to get shape and fit right . Took the hood off to make fitting easier but still needed help to avoid getting creases because one slight touch and it stuck like the proverbial l to a blanket !

Interesting that we have two very neat solutions above, One sound and one for heat!
F1 cars use gold leaf to reflect heat away from carbon fibre panels that are millimetres away from glowing exhausts.

Being a racing supplies business , they had gold leaf insulation where I bought my insulation from . Needless to say I didn`t splash out for that !
