Bailey motorsport dump valve

Or i could just replace the lot with nice brightly coloured silicone jobbies ! Where did you get yours from ?

Demon Tweeks are as good as anywhere else if you wanna go the silicone route. Its surprising how quickly it can get expensive, mind you! http://www.demon-tweeks.co.uk/products/ProductList.asp?cls=MSPORT&grp=MC047&pgrp=M025&tlgrp=MS004

Unfortunately, my car\'s in for paint atm, so I can\'t get the measurements off that. I guess the length might be a bit tricky for you to measure, then, but I\'d need to know the internal diameter. From memory, I think its 22mm or so?

Just had a little look through there, i see what you mean !!!
 
Gonna see if i can get a genuine part, Docklands Mazda still haven\'t come back to me...

Oops, sorry, dude. Had a rummage in my teetering pile of old RX-7 bits, and the hose you need is split at the end. Now I think about it, I\'ve a feeling that was what sent me down the silicone replacement route in the first place. Sorry not to be able to help

You need to take the Air bypass valve off which is the one nearest to your airbox, it\'s a little brown valve with ABV written on it, once that is removed it will leave you with 3 pipes, one the goes to the airbox, you need to block that one off, the larger one that goes to the manifold i think is the one you put the dump valve on and the small vacum hose goes on the pipe on the top of the dump valve...
 
With regards to the pipe being a smaller size to the dump valve, you need to get the fitting kit which includes a reducer pipe and plug for the pipe you have to block off on the airbox...

I\'ve been dicking about with this all over the weekend and been discussing it with a few people. I took the CRV (Charge Relief Valve) off and replaced it with the BOV which is further back in the engine, this was the wrong one !
 
Pearl_Rex, not so sure why yours is quiet, can you post a pic of where you have fitted it ?

Thanks for your help. I don\'t have an air box on mine; i\'ve got twin air filters. Although there are 2 pipes sort of just hanging there and i\'m thinking maybe they should be either blocked off or filtered or something!? :confused:
 
My dump valve is currently sat up near the windscreen on the driver\'s side. I\'ll try and get hold of a reducer piece and let you know how it goes. Thanks again,
