Dump valve hole.
Turbo Mini Forums

Hi, i have bought at last a mini turbo. currently the engine is standerd from a metro turbo, afew little additions like a intercooler, but its running standerd boost and has no dump valve..... i crave that little woosh soo... whats the best way of pluming it in to the plenim chanber? i can't do alloy welding and i don't know any one with the gear is it best to find a local compainy who would do it or does any one make them? or is there another way?
thanks Alex.

avon bar sell them, but tbh i thnk there expensive, a local company could p[osibly do it cheep (metty turbo knows someone that he got to do mine for ?30) or you could buy a fitting kit and just plumb it into your intercooling hose somewere? not as effective as the plenum but it will still work lol

HTH, Dan

easy to do yourself then have welded, shouldnt cost much. prep is the hardest bit (well most expensive! lol!) so do that bit yourself.

here's a pic of mine



sorry about the size of the pic but you need detail

Iain has your car been on fire ?

Nope Not while owned by me.

well, occasionally after some welding, its alex's car now

My lastest has been on fire a lot today, new inner sills, door steps and a few more bits have been done today.

I found the end of a water pump or thermostate ideal for the mounting piece (was gonna put flange but thought it might spark off pervy comments) They are alloy and have the flared end:>

Thanks All. just 1 more question. what type of dump valve do i need??? i was going to just get one from ebay.

Diaphram type is probably best, the piston type ones (like mine) stick after a while because the seals react with the fuel and swell a bit. I managed to replace my seal with one made from viton which does'nt react with fuel. Cost ?6 mind for a farty little rubber seal but works.

still find your spark plug amusing iain

T3Tone, do you have contact details to get that seal? i have a diaphragm D/V atm but wanting to get a baileys piston one sometime and will want to replace the seals.

cheers, Dan

top tip, can you give some details of the seals you used as mine is starting to stick

i have a bailey dump valve had it fitted for a year now and no problems pretty loud.

We now do a threaded dump valve. So all you have to do is drill and tap the plenum.
Or we can do if for you

how much would that cost? the problem is i have to take it apart to fit it, and at the moment this turbo is my backup car which im useing. so its going to have to wait till my 1380 comes back from the body shop.

pot_dan..

I got the seal from a company called bsl brammer, try www.bslbrammer.co.uk I had problems giving them a part number off there site!!! but what you need is a quad ring with a 33.045mm ID and a cross section of 1.778mm.

treaded dumpvalve now i like the idea of that dont need one but good idea

no longer a series, but still 1.3 turbo.

threaded dumplvalve, thats whats going on mine, as soon as i get round to sending my plenum in to avonbar that is!

ryan

cheers T3tone will give them a try think i have just got a baileys one off feeble.
i do like that idea Mr. Avonbar tho again i dont need one now as my plenum has been welded lol.
will be ringing you soon to order a lot of stuff lol

cheers, Dan

Could you not just drill and tap the plenum to take a male bsp fitting? These are avalible in loads of sizes!

yeah bet its just inch bsp. easy enough especially in alloy

Don't forget you can get bsp fittings in stainless,alloy & anodised

sorry to be stupied but BSP?? and its going to be abit tricky to drill and 1inch hole and tap it, wish i had that kinda kit.

fuck doing all that if you got an intercooler just put a T piece in near as you can to plenum

easy
