Polished inlet manifold

Hi there,
I bought a spare inlet manifold for 20 and 'ave been sanding and polishing it (knackered) all day.
It'll soon be ready and I'll have some piccies.
Was wondering if anyone else has bothered - or has tips to make the whole process of smoothing the ally down so it can be made to gleam!

looks bloody good m8. Have you thought about putting a lacquer or a clear plastic coating on it to stop it from tarnishing with the grime in the bay?

wouldnt have thought so as the plenum / intake on my last car, a vectra v6 came lacquered from the factory and these engines run hot since there was sod all space left in the bay.
Just need to find some high temp stuff to use i guess.

If you polish also the inside of the manifold, it will increase the engine power?

No not necessarily, the engine needs a turbulance in the air entering it to ensure a clean burn. I do know because of the way the scoobs engines are laid out (flat 4) they are very prone to the way the air pulses enter and leave the engine. Not instanly destructive shall we say but in terms of efficiency and could lead to problems further down the line unless its done by someone who knows the engines inside out and who can map it to suit.

Thats my tuppence worth anyway.

I agree. Time better spent polishing the inside of the Manifold.
I thought the idea was to get the air and fuel in spark and then gas out as quick as possible. Why have a large bore exhaust?

Top Job on the Manifold Polish
