Volvo Turbo Blowoff Q's
 

yea so i got a TD05-12B from a 740 DL, its got the blowoff on the compressor housing, is anyone familiar with this? i was just wondering if anyone knew what this sounded like, and would it affect anything if the top of it is a little crushed??? ill post pics if anyone wants to help me out with this/knows what the ---- im talking about. thanks.

the first one shows the bov on the compressor housing, the second one shows where it got crushed a lil bit, does anyone know if this will make a diffrenece.?

i had that same turbo.... take that bov off and completly fill it in with jb weld to keep that bitch shut... u dont want that on there trust me. even with vac it opens under boost... jus keep it shut and jb weld the ---- out of it and run a differnt bov on ur piping somewhere.... TRUST ME =x

thanks.. but i kinda used up my budget on other ----.. so ill have to use that one till i get money for a real bov. do you think theres gonna be any issues wit it being a lil crushed.?

Looks like the exact same diaphragm cap that comes on the 1G DSM, which is a great junkyard BOV. I was holding one up to the picture on the screen, identical in proportion.

The small dent doesn't look like anything from what I can see. People actually slip the DSM units into a vise and crush the whole top (dsm.org has writeups) to increase the spring tension of the BOV for higher boost apps.

I suspect turboDA6 had a defective unit, or poor vacuum supply to the BOV. If the spring tension of the unit is low, as per a 6 psi *automatic* turbo car, I can see where it would get blown open if you had a few psi pressure drop in the charge pipe. At that point, crushing it should take care of that problem... O0

yea the turbo is mitsu made for the volvo 740dl for 3 years... so what your saying sounds good. thanks.

Re: Volvo Turbo Blowoff Q's
 

yea o saw one of those at a local yard. I was gonna take it just to sell it. BOV/Turbo combination... I'm sure it works fine... just shitty if one or the other components break...

Re: Volvo Turbo Blowoff Q's
 

to where does the air/pressure escape????

Re: Volvo Turbo Blowoff Q's
 

it escapes back towards the turbo inlet. self recirculating... im telling u i tried using that bov. its designed kinda like the 1g bov but its spring is so soft it can't hold boost for ---- =x that piece of ---- would open under boost then flutter when i let off like it was clapping open/close open/close... if u dont listen u will regret how ur boost feels. u get 4-6 psi tops then it opens. n stays open acting like a hole in ur ic piping. feels gay n sounds worse.
