Turbo technics say i must have a D/V, ideas please?
turbo went today, they said over the phone that i must run a dump valve,
i prefer chatter but understanderbly i would rather have dump valve then
rather go throught the rigmorole of changing a turbo every 3 months,
does any one sell dump valves that are quiet or recirculate as i prefer chatter
cheers troops

wont a recirculating dump valve get rid of the chatter? cos chatter is back pressure on the compessor wheel? so and recirculating valve will not put it to atmosphere but put it bk into circulation rather than allowing bk pressure?

Andy i hate dump valves and was gonna take mine off my s1 its a 1.9 with all the trimmings and a stage 2 hybrid but after reading this im just going to leave it on mate.
I think its worth loosing the chatter and putting a DV on if its gonna stop blowing your turbo

I'm running 14psi on a 2.0 zvh, i've just removed the dumpvalve is this gonna cause any damage to my turbo over time? If it is then i will refit it, but would rather not.
Cheers, Mark

What turbo do you have? Need a dump valve
None of my mates use a dump valve on their cars and they don't chew up turbo's like they are going out of fashion. Mr C runs 28psi held on a GT turbo and has no trouble.

for a month and preferred it, ran a lot better and seemed to pick up a lot
quicker, the car is running 21psi, now i get told different things all the time,
technics say i MUST run one but like you say, C & B run with out one,
the oil line has been tested and is pushing out 58psi, engine is 8k old and
everything new, i.e, hoses, oil feed pipe, i have bought a bailey
breather to fit once turbo back on, i dont want a dump valve.

but the first 4 were dodge and were not good as soon as they were fitted
to the car, they were done by a local firm, turbo force, aka turbo farce, LOL,
they alll had inbalanced shafts and could not take the high RPM

you cant use a recirculating dump valve with mfi as it will confuse the metering head and technicaly make a massive air leak!!!!
you defo dont need a dump valve!

Had three DV's including a twin piston Bailey job over a period of 3-4 years and the car was never right with any of them. Best thing i did was file them away in the spares drawer. My Escort doesn' have one and my Fiesta won't be getting one either

Does the car have an Airleak or something else maybe that is causing the Turbo to overspeed? That seems very likely IMO. It should not be spanking turbo's at that rate, in any case.
Sorry if you already said and I missed, but in what way have the last 2 or 3 failed?
As Tony said, I run close to 2-Bar on what is considered one of the most delicate type of Turbo, the GT Series, and have never run a Dump Valve.
I used to run similar boost levels on my Stage 3 T3 too.
To be honest, yes to run a Dump Valve will increase your Turbo's chances of surviving, but when you stack all the other odds up against it, there are so many other things that can kill your turbo first.
Turbo warranties aren't worth sh1t in my opinion. As soon as a Turbo fails under warranty, it will have mysteriously been subjected to either a 'Foreign body' or 'Oil contamination'. Both of which are hard for you to fight anyway.
My money is on an Airleak. Start with your Throttle-body to Inlet Manifold Gasket.

Christian and Beccy
thank you, that is getting changed any way as i have a new inlet manifold
to go on, the first 4 turbos where done by turbo force and they did not have a good enough
machine tyo test the turbos to 150, 000 rpm so they were never good enough

As above i think the problem lies else where six turbos Surely thats telling you that there is something wrong whats the chances of cooking six units in under 8000mls without crazy boost id get the turo replaced and then get it booked in somewhere to try and identify the problem Good luck
