reaper was quite interested in it.im waiting on him but il let ya know

dont know if i can help u guys out but my missus did this to my im for me by hand took her a week but looked good:
half way through sanding

almost finished



all done by hand diffrent grade sandpapers till smooth then polished with a polishing thing she has got she said she dont mind doing one or 2 for u guys as long as u pay materials and obviously supply the part just bung her a couple quid for her time they wouldnt be as good as if done on a machine but as u can see still very shiney.

Was I the only one thinking it was the inside of the manifold that you'd want polished?

mines been done both

na i did want hte outside done for now, but the inside will be done later on once i start workin on performance

i got my heatshield polished up but no where near as good as that. i went up to 2000 with paper. what did you use???

whats that? grunt grunt...............

our intake is sold to reaper so sadly not available guys!
mr tatlock-get digging in the garage

ahh dammit. well considering loads of people have said it takes an ages and 4 blue moons mine dosen't seem too bad now considering it only took a couple of hours. Its nowhere near chrome but does look cleaner and more reflective, just not blingbling haha

When you say 4 grades of polisher and 3 grades of polish how do you mean??? can you name some??? cheers:D

ahh okies ill have a ganders:D cheers dupe

Thinkin about it....what the hell is an overboost and airram???? i know they sound pritty self-explainatory but how does it work??

both types of intake manifold-airram is the best you can buy

IF someone wanted to post me a spare, id be quite happy to 80% prep it for a small fee. Its the last odd and sods that i wont have the time for, but ive done mine

sounds a good offer

it is about 400 hours labour.

Alternativly - what about getting it chromed? Duple, would it withstand the heat?

yes it would withstand the heat but it would be mega expensive id say.chroming has gone really expensive last few months

Dupe- so how do they work together???

Androoooooo - Your only in sittingbourne aren't you??? if your cool with it, ill see if i can get hold of a spare and drop it down to you?? how much would you want???

1- Port & Polished Intake Manifold
Think of the air going through your engine like electrical current in some wiring circuit, starting at the intake filter and ending at the exhaust tip. Along the way, the circuit has different resistances to air flow. In stage1 we have just eliminated the main restrictions to air flow by changing the major and more important parts to less restrictive ones . But is that all resistance that air charge faces? Fast answer is No. The basics were the major required changes to let your engine breath faster and easier, but there are still others to play with, and one of these is the intake manifold.

In this upgrade, the intake manifold ports mating the cylinders, and the intake port mating TB be machine for slightly larger sizes. Also the internal runners of the intake manifold will be chemically treated for smother surfaces, and in some cases the chemical treatment will etch little of the runners wall to even increase the cross sectional area of these runners. These changes combined will allow the air to flow more easily through the intake manifold to engine.


Gains: 2-4bhp


Earlier there was an aftermarket intake manifold for coupe (Air Ram IM), that used to completely replace the stock manifold and giving this advantage. But the Air Ram IM is not available in market anymore.



2- Big Bore Throttle Body
With your aftermarket intake system, and the custom work you had in your port & polished intake manifold, the stock throttle body now with its stock bore size is a bottle neck for the intake air charge. And it is feasible now that if the throttle body bore is increased it will help further to decrease resistance to air flow. No matter how small the reduction in that resistance is. If you are after every horse out of your naturally aspirated engine, then with this you might be able to extract couple more of them.

Gains: 2-3bhp


Here it is good to point out that doing PPIM & BBTB together will be more fruitful to your desired gain. And if ever you would do only one of them don’t let it be the BBTB without porting your intake manifold.

This is a pic after about 6 hours sanding and polishing, a good diy if you have a spare day or so but you'd never make a living at it
