Ive got the incentive back to finish the cossy and im just wondering what dumpvalve would be best to run with a GT35 turbo.
The cars off back to Harveys this week to be checked over so i need to get a dumpvalve sharpish

pee vee

not on topic, but nice one on gettin the incentive back!
didnt you sell a load of it?!

Don't need to run one apparently, as the shaft is strong enough to cope (so I have been told by my turbo vendor )

rather you than me some have fitted 2 dump valves just to make sure they are not as strong as your turbo vendor thinks

I was told I could use it with full anti-lag no problems

John

speak to martin h he will tell you all about them he has used a good few now and he will put you in the pic as he has experiance with them

Jon(m600)

Cheers Lads got pissed off with sinking money into Fords But im back on track(32 PSI here we come)

I was always told you had to Run one or more dumpvalves with these turbos because the shafts are Fragile

Dunccoss

good on you mate, get it sorted and injoy it

any tuner views on GT35 and ALS aplications and shaft strenth plz?

Billabong

I can't imagine many of them would entertain the idea!

spot on!

Wil,
Your turbo vendor is best avoided, as they are VERY weak compared to a T4 and MUST have both a dump valve AND the water-cooling attached or they WILL break . They will also only take mild anti-lag, as it does not have a maram shaft .

It WILL break without dump valveSSSS

RWD_cossie_wil

iTrader: (9)

right, shall be having words then

SapphyMike

what about on a GT30? 1 or 2 dump valves?

Alg1k

iTrader: (2)

Depends on boost but if you think about it the less you stall these turbos when you shut the throttle the better
A gt30 will take more than the bigger turbos before it fails

Jon(m600)

Gutted because i dont like the noise a dumpvale makes But if it saves my turbo then who am i to argue

Martin-Hadland

iTrader: (2)

get a recirculating one then!

Jon(m600)

Is that like the setup the rs500 came with as standard? and where do i get one from martin?

Martin-Hadland

iTrader: (2)

yep, same...... Bailey do them, i might have one in stock at work or you could pick one up at Ford Fair (if you are going)

Jon(m600)

How much are they m8 and what they like to fit?

Mike Rainbird

Piece of proverbial, this is on my Sapphire, but you get the idea:





Retail price is £103.98, but as Martin says, you should be able to pick up a deal at one of the shows.

I run this sort / set-up on my Escort as well (but with dual piston internals for the ALS). Best dump valve on market IMO.

wimwerf

best recirc dv on the market....

Stavros

IMHO I cant see them bailey recirc ones flowing all that much air, some other aftermarket recird ones the valve opens far further so should dump a lot more air.

Jon(m600)

Cheers for the pics mike So it dumps the air into the Turbo inlet? and does it come with the connector tubing and what actually goes into the cooler/inlet manifold hose?

Jon(m600)

Forgot to say i will be going to ford fair so whos got one?

Mike Rainbird

iTrader: (3)

Which is why it is so good, dumps just enough air to prevent damaging turbo stall that occurs with big turbos, but not enough that it makes it laggy as fook when the throttle is reapplied .

Jon,
NOTHING, this is where the air comes OUT and goes into the turbo inlet. You have to supply the tubing for this. On my Escort it is some copper heating tube to hide it under the slam panel . "Proper" plumbing . Mr Bailey will have several .

Jon(m600)

Right so if ive got this correct The air that is to be dumped travels along that long bit of tube and through the dumpvalve and into the turbo inlet and doesnt make a pppttttiiiissssshhhhhh noise

Jon(m600)

Good job im a heating engineer aswell Jobs a goodun!!

Mike Rainbird

iTrader: (3)

That is correct. However, given the fact that you have a chav-tastic cone filter , the noise will not be very well dampened .
