Yeah I really wish I had more knowledge on motors but oh well. 12 years on and she still breaths.

Just out of interest why do you want to heatwrap manifold? I was told its a bad idea by a BMW race technition that built engines for BMW race series cars!

He was explaining that all heatwrap was designed for exhaust systems on stripped race cars so that heat didn't transfer under the car & threw exhaust tunnel into the car making the car a sweatbox for the driver!

He said as heatwrap is designed to keep heat in, by wrapping your manifold etc is just transferring the heat back threw the head, which isn't ideal which when you think about it, it makes sence! People do it for show coz it looks good but it dous more harm than good.

They wrap exhausts around 10inches from manifold/turbo elbow so its dousnt create exess heat towards the head!

Just a heads up

I was told in keeps engine bay temps lower and also that the hotter the air the faster it flows

Enough cooling for engine bay on a R & maybe im not sure but better flow would be down to ported manifold, uprated elbow & 3 inch exhaust id say...

Im no expert lol but after what that BMW guy explained about it keeping heat in towards the head etc makes sence as its just more excess heat so id preferably avoid it tbh

Fair comment bro. I’m not too sure now. I’ve got the 3 inch elbow.

How many mm have you ported out?

A lot of Big power cars have been wrapped. Need more feedback

If you look at a lot of race cars or highly tuned time attack cars none of them are wrapped, there cryo treated as that dispursess the heat in a dbetter way but think that's quite expensive... If not getting it cryo treated then id prob just leave it how it is, But personal prefferance I suppose

Cryo more for Gear Boxes and Running Gear.

Manifold maybe, but it would be done so that the Manifold doors not crack at the seams under extreme temperature.

It does not increase the flow of the manifold or keep it cooler in any way.

Again this is just info I’ve picked up. I could be wrong

Side note, how many highly tuned track cars/time attack cars sit in a traffic. If there's a constant movement no point wrapping it. Wrapping a many or downpipe helps it keeping localised.
