looks like a crock o poo to me...too many tubes!!!!

It looks simular to the extreme boost one, but not as shiny... But with 2 too many tubes!!..

steve b · Post by **steve b** » Sat Jan 15, 2005 11:07 pm

why too many pipes? there are 4 that are just split in 2, presumably with the same theory ar the twin entry turbo??

ERM....LOOK AGAIN DUDE

i don't get it what am i missing...

looks like it'd line up where are the 2 extra tubes?? the feeds for 2 cylinders have been cut off.

still not convinced...if siamese induction tracts were such a good idea then why are they wasted on the head?

Has you guys seen the standard manifold for the Rev 1/2? They have those same twin intakes (2 intakes per cylinder) This is because of the TVIS setup. You need to have twin runners for each cylinder to be able to close one off for an increase in low down torque, and open the second to increase top end flow.

The reason that manifold retains them without the TVIS is because i looks like he's just cut the standard runners off the manifold and wielded them onto a custom plenum chamber.

The reason they don't split in the head is because theres only a needed for the TVIS to work, there is no point carrying on the Split runners after the TVIS. You will also find that the start of the head port size on the Rev 1/2 is bigger than the Rev 3+ to accomidate the extra space taken up by the divider on the manifold flange.

so it could be a good idea then.

I thought you lot who were saying 2 to many tubes were the blind ones

whos cylinder head is that?

what revison car is it off?

mine, well it was, before it had a shim under bucket conversion and a set of performance cams from Vmax performance (american twosrus supplier) and then sold it to a bloke called Navs

It was from a rev2 N/a but when it came to be re fitted a crack in my block was found to be the issue not the head gasket as suspected,... it was here that the decision to put a turbo lump in took over

Its not really a benifit to the manifold design, only that you have to have this for TVIS to work correctly.

If your not using TVIS then don't split the runners, if you are using TVIS then you have no choice.

We'll be selling a custom inlet manifold soon, should be ready the start of feburary. Will make two options with split runners or single runners. Initially for rev1's and 2's

That one on ebay looks very bad, the welding is all over the place. Thats the problem welding two cast alloys together especially if their dissimilar.

Is this feeding from the centre a real problem or is it myth, it would surely be worse feeding from one end only? Can't see it myself.

Some very high powered stock turbo cars feed from the side this way i.e. evos

I've gone for the RMR one. Should be here in the next few weeks. Had them fit a rev 3 TB to their centre feed manifold for me.

Lol ! they should have fitted a chargecooler core in that manifold with the size of it... people are gonn think you've got a supercharger bolted to your engine as well !

stevecordiner · Post by **stevecordiner** » Tue Jan 18, 2005 10:53 am

Lol ... note to self, fit spark plugs before manifold and chargecooler

Well, it'll be interesting to see what gains it gives

Owen @ Kent Car Craft · Tue Jan 18, 2005 1:18 pm

JAMES! Thats what we need,a supplier in the UK for maifolds etc,especially for rev1+2's
I'll be wanting one straight away!
Are you likely to be pricing them to compete with the RMR units?

Fonzy · Post by **Fonzy** » Tue Jan 18, 2005 1:44 pm

That welding is cack! my manifold is done in the same way but welded ported and polished to a pro standard, the boyz in the states do this as common practice,
Oh by the way the beast is in the car now!

How are you going to get the chargecooler to mate up with a centre feed manifold.
