BOV mount experiment

[jjorgensen52]

I'm working on a mount setup for my BOV based on the TB plate, which has approx 5/8" draw from the turbo side of the intake. I've fabbed up a *rough* first version of this using an HKS style BOV mount. Thought I'd share a few pics for those interested (forgive the weld quality, I'm on my second day of MiG and still need some practice :roll: )
Top:

Underside of TB plate

Mounted:

With stock style IC

Very rough size comparison to HKS valve

Re: BOV mount experiment

those are some big f'in welds.

Interesting idea though:tup:

Re: BOV mount experiment

i thought the tb plate was after the throttle plates if so then the bov will be useless.

Re: BOV mount experiment

yeah, you need more practise welding..

but its a start.. and yeah.. i think the throttle blades might be infront of the plate..

interesting fab up :tup: ...but i also thought the bov is supposed to be before the throttle plate???i need to find this out before i try puttin mine on.....

Re: BOV mount experiment

have your intake and ic bead blasted, those are dirty as hell.

It is, if it was behind the throttle body, it would not work properly.

I had the same thoughts as well, sitting right on top of the TB, you are almost halfway on each side. You would have to make sure that it was completely sealed on the intake manifold side of the throttle plates. Then, make sure the path up into the BOV pipe flowed as much air is needed to effeciently blow off.

Always good to see creative thinking put into real world projects. I would like to see how this turns out, and I hope for the best.

Re: BOV mount experiment

you may need a cowl hood if you already don't have one

Re: BOV mount experiment

The Throttle body does have a source in the front of the plates (the space between the two bores). I am not sure if their is a enough air flow through that opening to disipate all the of pressure created by the turbo, (I think the passages get narrow) however it might be good enough though...

Re: BOV mount experiment

from what I looked at the TB flow (on my new BBK 58mm) is about equivalent to a 5/8" internal diam. pipe... I believe it could be opened up a tad more, but I haven't check too much. The stock one has a larger (and weirdly shaped :lol: ) passage.

yea, I know . Going to an RPM front mount a2a and having the intake cleaned before install.

you may need a cowl hood if you already don't have one

I'm about 99% sure this will clear, hence why I angled the front side of it down, but I haven't got my engine right now to check. If it doesn't, the pipe size could be reduced slightly, or just sort of flattened out towards the back of the TB plate. Last alternative is to angle the tubing down after the TB so the valve is next to the IAC thing instead of above and to the left of it (but I don't have tubing bending equipment, so my ability to do that is low.... )

Re: BOV mount experiment

Why not just have a flange welded to an end tank of the A2A.
This would be a cleaner and easier setup.
Less chance of leak and stock hood can surely be used.

at this point, because my welding skills aren't so great and I didn't want to mess up the a2a (which is beautiful, btw). The real problem was that the steel tubing to the intake is powdercoated and I don't want to have to remove it all so I can weld the flange to it and then recoat it :roll:

in the end, I'll probably end up having to make a 2nd edition of this, but it's not a hugely pressing issue to have the BOV since I haven't got a motor to put it on right now...

Its nice to see people trying new ideas .

I have a tendency to do this kind of stuff when I have time on my hands ... this is getting way more feedback than I thought it would, by the way :lol:

Re: BOV mount experiment

May be an aluminum TB spacer that could be bolted in front, carved and ported, then weld the final part on to it? I think it would take care of the TB plates issue.
One more question, could this be done in fiberglass and withstand the pressure, heat and vibration?
Im wondering 'cause im very good working with fiberglass, when i brought my Sy to Mexico i lost the front right cladding and had to make a mold of MDF from scratch. You can't even tell the glass from the plastic one.
Thanks.

At least you aren't off welding turbos onto Geos or anything crazy like that :rotf:

Nope, I didn't have any suitable donor vehicles to play with :rotf:

Re: BOV mount experiment

Whatever happened to this? Was it a success or not?

 

[skipztt]

Re: BOV mount experiment

u need to tig that aluminum. also helps if the aluminum is very, very clean (clean with lacquer and sand off any paint and gettt of any grease od junk that is on it.)

also if you could preheat the aluminum that helps alot. just giving you some tips...good job, hope it works out

Re: BOV mount experiment

Well, I'm still running on my truck as we speak. It does function flawlessly, it does not move as much air as a traditional style BOV (there is room to improve with some port work but I didn't bother). It's more of an insurance than anything else, it does help to reduce turbo flutter except in the most drastic WOT cutoffs
