EGR Intake and webbing - needed or not?

[FricFrac]

Normal disclaimer - yes I've searched and read literally for hours but the results are inconclusive.....

 

With a EGR intake on an L28 (mine is an F54/P79) if I choose to use the heat shields is it better to leave the webbing in (trapped air as an insulator??) or remove some of the webbing to release the hot trapped air to reduce heat soak on the intake? I know if you aren't using the heat shields traditionally the webbing is removed or a non-egr intake is used.

 

My thought is that its likely optimal to use the heat shields and remove the webbing but I'm far from an expert on this one....

That is what I did when I was using a stock manifold. It seemed to be the best solution to me, although I don't think anyone will be able to give you more than anecdotal advice.

 

I did go the extra step of ceramic coating the bottom half of the manifold to reject IR radiation from underneath while allowing heat to be dissipated from above.

I'm putting in a ceramic coated header which should help. Since its ceramic coated is there any advantage to wrapping the header and will moisture be an issue if it's coated?

i left in the heat sheild and removed the webbing, manifold is touchable when running normally now, before i couldnt touch it. i havent seen any increase in mileage or power, but i havent dynoed it.
