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!

My arm feels like its going to fall off !
Just got the final wet-sanding and polishing to go - hope it looks ok fitted

Looking good Sean. Nice one!

That is commitment to making an already awesome car that little bit better, improving the looks of the engine can only be a good thing

Sean Hath · 28 Apr 2008, 06:30 PM

Well, I've been sanding and buffing all day long and I think I'm done!
What do you think?

80% done

Finished !

Going to go have a little nap now!

Wow! You deserve a nap sean. It looks great.

Anders52 · 28 Apr 2008, 07:22 PM

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?

dannydumpvalve · 28 Apr 2008, 08:49 PM

Sensational effort Sean

Worth more than a nap mate. If it is lacquered wont it burn off when it gets warm???

Anders52 · 29 Apr 2008, 07:51 AM

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.

very nice work mate,sure it will look sweet when fitted

Sean Hath · 29 Apr 2008, 01:24 PM

Yep, fitting is the next job to be done........waiting for a sunny day off, couple of beers and the 'ball and chain' out of the way

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
