just wondering how long the turbo would last with no dv running at say 1.2 bar ov boost? come on all you experts

 

td05, ages

 

just to add its on a my 92 wrx with water injection soobyecu and induction kit and a knock link and a dawes afr full decat if it makes any diffrence

 

Whilst playing around with fmic pipe work I ran my TD05 which has done 140k miles with no dump valve for about 2000miles and no ill effects.. seems very strong.. and as Pavlo says it should last ages..

I just cringed at the chattering noise and visualised the blades stalling all the time so as planned fitted the dump valve in to the pipework now I have finished playing with samco (for the moment).

As mentioned, they do make a noise but survive it ok. I was running 1.8 bar on a td05 with no dump valve for a few thousand miles with no problems. Opinions differ but I found that it improved spool up between gears.

Andy has a good point about the spool.. I found no dump valve was better spool between gearchanges than the standard dv but that the Forge I now have fitted was as good as with no dv and no cringing noises.. lol

Your just a hero mate!

 

Just the person vulnax999 and on the subject of dump valves..
Do you know which spring colour you have in you Forge? I have a couple spare.. save you buying the complete forge tuning kit..

I am currently running a f/e TF05 with no dump valve at 1.4bar with no issues (apart from the size of my injectors).

Spool up seems far crisper and lag between changes has reduced, with some real nice chattering on full boost changes.

Andrew...

 

i tryed it today i dident get any chattering noises. tbh it all sounded the same with as without the the dv. is there something wrong. it sounds like its blowing air back into the induction cone but it sounds like that with the dv on iam comfused

 

What is the dumpvalve and was spring?

It might not have been dumping already if spring to strong..

Easy check is to refit it and remove and block (with a bolt) the vacuum line to it and refit to test as with no vacuum line it shouldn't dump etc...
