Intake manifold

[Peter Empson]

I've just bought a spare intake manifold for my car for reasons I'm not entirely sure of (eBay strikes again...). The way I justified it to myself is that it would let me have it powder coated black to match my cam cover.

But I've also been wondering if there would be any performance gain to be made by having the insides polished?

I'm guessing the answer is probably not as I think its claimed Porsche did a pretty good job here, but maybe that would be different if I eventualy go ahead with a super-charged setup?

Best regards,
Peter.

Pete
Good minds think alike.....[][]
I was looking at the same manifold, to do exactly the same thing......Polishing that is...
Let me know how you get on....[][]

 

[Peter Empson]

Lol, sorry if you were bidding on it, originally I only meant to see if I could get it for its starting price of £9.99 []

However the good news is that once its fitted the old one will be spare, so that will be available!
Best regards,
Peter.

 

[Big Dave]

Pete . I didnt bid on it ...
How much did you get it for.??

I might be interested in your "old" one....

 

[Peter Empson]

I got it for £40 plus shipping, not a great bargain i'm sure, but seemed reasonable enough to me.
Once I've done whatever it is I'm going to do to with the new one and had it fitted I'll certianly give you first refusal on the old one.
Best regards,
Peter.

You can get it thermal coated both inside and out.

I guess the advantage on the intake side would be to keep the heat out, and the air going in cooler, altohugh in reality I wonder how much real difference this will make on all but the most modified cars!!

Then again, it will look pretty good, and is available in Black, Chrome, or a nnumber of other colours. They also do calipers, exhausts and engines. Before the "big one" last year, I was going to arrange a group buy, getting my exhaust manifold coated (it still leaks now!!) I might resurect this later in the year, as I'm thinking of getting my calipers done also.

Thanks Carl that looks interesting, although as you say its probably best for those running serious boost.
I think I'm looking for someone that can offer a similar service to http://www.gethoned.com/ but in the UK.

Irritatingly its all looking a little immaterial now though, was cleaning the dirt off the intake this morning and discovered it had a hole in it (in the main chamber area) that was filled with epoxy []
I've sent the person I bought from an email and will see what he's got to say.
Best regards,
Peter.

Can you use the hole to mount a temp sensor or something if the seller doesn't want to play?

Carl, depending what I decide to do I might have a set of uncracked and already coated exhaust manifolds available.

 

[carlmthompson]

Great - keep me posted!

 

[Peter Empson]

Well despite a couple of pleasent emails to the seller via every email address I've found, it seems they are ignoring me. A very bad show in my opinion as this appears to be their trade (they are a Porsche breaker based in Wembley I believe)...

They're even selling another S2 manifold at the moment so its not like they couldn't have solved the problem easily!

Sadly (stupidly) I left feedback before thoroughly checking the part over, I merely checked it was in the box as it was too grubby to go over properly and knew I wouldn't have the time for a few days to clean it up.

Its not the money I've wasted that bugs me, but being ignored in the hope that I will go away really iritates and makes me do the exact opposite...

One saving grace is I paid for the part via Paypal and I am considering contacting them to see if they can get me any kind of refund.

Fen, the hole is right on the corner of the main chamber against the brake servo so there's no room for a sensor to fit in, even if I could think what to put there!

Best regards,
Peter.

Can't you edit your feedback? Never tried it myself, but I know you can change it to mutually remove a negative feedback if you subsequently resolve a problem, so it must work both ways.

 

[Peter Empson]

Thanks Paul, I believe you can add a follow up somehow, but not ammend the original one unless (as you suggest) it is mutually withdrawn.
Best regards,
Peter

I guess I was thinking intake temperature. What about threading it and fitting a plug of some sort, then cutting off the bit sticking out? It sounds like you won't really see it there and the flow won't be compromised significantly.

You can claim a refund if the item is "Not as described" i.e. there was no mention of the repail/bodge.

 

[carlmthompson]

Paypal almost always site with the buyer, so claim a refund via them, and hope that the seller doesn't reply - that way you get a refund and won't have to send the part back [].

Happened to me after one nice chap ripped me off with a broken BMW Computer - chap didn't reply to any e-mails or Paypal, but after I got my refund through, he then contacted asking for the item back, so I got my own oppertunity to ignore[]

If you're using a new gasket I would not bother with sealant, unless you're aware of warping or badly pitted surfaces.

 

[TTM]

Though it may not be necessary I always add a bit of sealant as I'd rather make sure the intale is perfectly sealed than having to take it off, which by then may well require sealant anyway.

 

[gajh]

Thanks for the replies, it is a new gasket but think i will put a bit of sealant on just to be on the safe side.

Thanks

It really shouldn't be necessary mate.
