as subject. does anyone have any experience with this ex manifold.

 

the only people i know who had one is ian howells which i think got sold to brom

 

a mate of mine did have a 909 manifold waiting to go on his motor

but he never got round to build it and sold the car

did have a garage full of spares, may well still have it

is it the same one you mean?

 

i saw one on the site of mountune.

the original 4wd one


the wrc 4wd one for my 4wd saph.

 

yeah that looks like what he had, i shall find out if he still got it

 

experience i mean does it fit straight on, does the turbo fit straight on, do i need a turbo damper.

 

anyone?

 

most people on get 2wd manifolds as its capable of flowing enough for 600BHP

 

We was after one for my Dad's car but couldn't get hold of one. Even Mountune couldn't supply....

 

i know rene. but this looks ok to.

 

Ian (Racetek) didnt have a genuine one.

Genuine ones dont mate directly up as a straight swap for the 4x4 manifold, cant remember what bits dont fit, but they dont

If its meant to mate up to the WRC IHI turbo then i doubt the manifold/turbo flange fits either.

And doubt its good for much power as WRC cars are barely over 300bhp...

 

so you mean a wrc exmanifold from mountune is no good for my saph 4wd.

 

AFAIK you would be better off converting to the original 2WD type, especially if you are after big power. The 2WD ones flow really well and are quite cheap........if fitting a T34 or T4 you will require a damper/hanger.

 

The Mountune 4WD version was prob developed to help minimise the effect of the mandatory 34mm restrictor

 

according to mountune it has a good flow. better then the original one.

cheers

 

Do they mean "better than the original 4WD one" ????

 

yes a lot better.

do you have the internet site from mountune.

 

From Mountune site:

http://www.mountune.com/acatalog/C99682.html

 

All well and good....................BUT Ł620.00 + VAT

I mean how much better than a 2WD drive is the Mountune item?

We "know" that the the cheap as chips standard 2WD manifold is good for 500 BHP and beyond..........At the price Mountune are charging you are well into the price bracket of custom built units with external w/gate provision.......with maybe some change left over

 

i got a feeling it places the turbo in a different position to standard, meaning modded boost pipes, modded downpipe, and possible problems with it hitting the brake resovior etc on RHD cars...

and of course 2wd costs 50quid and is good for 600+...

 

That'll be the 'Mountune tax' Doug, lol Look what they want for a bare block ......

I tend to agree with what you say, just posted that up for reference, and to clear up the 'what turbo' issue.

 

How much are the stainless manifolds in the UK then?

I know know which i would choose

 

here is a costum job http://se.mobile.de/SIDxgXXQdDIv1UY3...8562123&top=1&

 

ok...the original one is good for 430bhp so this one is better. how much i dont know.

about the price your right. there expensive.

the manifold looks good.

i was looking for a manifold without using a turbodamper. thats why i'm asking around about the manifold.

cheers

 

do the tubular ones crack or do they last the sort of mileages you would want on a road car?
nice weight saving from up high though

 

The Cossie dampers are no problem to fit or maintain.........and not too expensive either. But the damper to me is as close to a "bodge job" from the factory as it's possible to get.......IIRC there is a resonance inherent in the YB engine was causing the 2WD manifold to fail - even while Cosworth were doing early dyno development at light loadings/low/modest revs

 

nice manifold.

 

The Original-- the manifold is cast iron not stainless steel so wont crack

 

the manifolds were not the problem, newtons third law is the turbo tries to twist the manifold off the head due to the reaction against the exhast gasses hence why a damper is needed

 

ok but the 4wd ex manifold dont has one.

 

becasue the 4x4 manifolds are much shorter /stiffer in torsion they dont need a damper

 

cheers

 

If a tubular manifold is cracking, I'd suspect the material.

321 stainless is *much* more resistant to cracking than 304 stainless.

Wall thickness will obviously play a part as well
