Just wondered if there were any gains from them apart from maybe de-airing the water system more easierly?

I wana go standardish looking engine bay, and also dont like the fact you cant see the water moving or your level with the bailey tanks, and i need a bailey tank to run feed for the swirl pot...

so can i get rid?!?! lol

just wondered your views lads...

 

I don't know if they are worth it or just a fancy item to tart up a bay - i bought one that was rough - blasted it and painted Matt black

Got it for pence for it and would say thats the only reason i bought one - put it this way i wouldn't pay £100 for what they are.

 

Anything to help the water system out, though I'm unsure if it's the best way as some water aswell as air is then returned to the tank and doesn't make it to the radiator for efficient cooling. Anymore thoughts on this?

 

I have a header tank that has the pipe coming out of the neck, i presume that is to get rid of any air taken back to the tank above the water line

 

hmm interesting, maybe buy a new clear header tank and have an extra port plastic welded in....?

think this would work? never tried plastic welding to be honest, lol

 

surely where they're situated the water would be cool going to the tank from the swirl pot as it's before the engine or have i got the cosworth flow characteritics wrong? and does it go the other way?

all i can see it doing is sending cold water and what bubbles you have to the header tank, but the header tank would be a better way of de-airing as it's higher and the bubbles will go to the highest point?

 

You've got it the wrong way around, the flow goes from bottom to top engine wise, ie opposite to the radiator where it enters at the top and goes down.
They are used primarily on very heavy boosted cars that develop hot spots in the water around the cylinder/jackets, this cases air to form, but so long as the return from the highest point is working ok, ie from the turbo this will return any air to the tank, so not really needed imo.
I think on the vast majority they are a gimmick, I would never have a metal tank of any make, as like yourself I like to see my level, don't try plastic welding the tank with another fitting, if you wanted to you can always "T" into the turbo return line with no problems.
tabetha

 

ever since i fitted mine i.ve had trouble with fans kicking in, untill i drive the car at full boost they dont come on which is k right problem when i started the car up at alton towers and qued to get opeople?an hour!lol any ideas people?sorry to hijack your thread matey

 

if you do get rid, PM me

 

so surely that means it's sending cooler water that's just come through the rad to the header tank again?

ok, maybe ill paint the swirl pot black like the hoses and get a standard tank so it looks kinda stock...

 

i dont mind at all matey, rather people get the right advice etc etc

 

Cheers mate shame im still waiting for the advise lol. Its sorn for another month so i'l post up then if no luck

 

Im not sure your getting it bud...
The water come from the head then through the swirl pot then to the rad not the other way round.

 

use a spec r one mine has a nice big window on the front

 

Not really needed

 

arhhh!!! there you go, pennies dropped, cheers gav!!

im a slow southern fairy i know.

 

As well as the before mentioned spec-r tank which has a sight glass to see the level of the water so too does the pro alloy tank

 

If they are worth it or not, I dont know..
But my RS500 had one fitted back in the 80´s
(when it was given a light touring car setup)!
It has to be good for something?

Good or not, I have it on all my Cosworth´s...

 

Bump, bringing up a old post cause I'm just getting my engine bay refurb, lol

 

I have a brand new spec-r one for sale if anyone is after one!

 

Oi, do one James this my post!!

Lol
