finally finished my V-mount
well, its 90% finished.... just need to get a better radiator, and make some ducting, but tell me what you guys think. anything mechanically wrong with it?
and before anyone says anything, the turbo will have a filter on it before the engine actually runs.... and all the loose wiring will be taken care of. don't worry. lol.

Also is that the stock radiator? I always wondered how much air will go through the radiator with this setup; mainly because it sits so close to the engine.
This seems the intercooler will work more efficiently than my setup since it's getting fresh air, not air that's been through the rad already. And you'll definitely need a vented hood and some good "ducting" to keep air going through the IC and not just all over the engine bay.

The plumbing could have seriously been better. That BOV flange is a totall turbulance maker, also investing the 100$ for a more direct throttle body elbow would have helped some.
Im curious though, why choose this type of setup? where is the air going to come from to cool this intercooler?

uh..... from the hole in the front bumper.... same place the air comes from to cool your front mount setup....
how could I have made the bov flange work any differently? any bov flange I've ever seen gets welded on the same way... I guess I could have made it a little bit shorter... ?
also, does it really matter which side the bov is on? I've seen more pictures of cars with it on the turbo side of the IC than on the TB side.... plus the stock bov is on the turbo side...
and yeah, I could have done the different throttle body elbow, but then I would have had to make a much sharper curve to still make it around the PS pump. I seriously doubt I'd notice any sort of difference by switching to one, and it would have been a lot harder to make the piping all fit right.
as for the vented hood... that will come at some point... for now I have an extra stock hood to play around with.
yeah, I do need to do a lot of ducting to make sure the air actually goes through the IC and rad... and I need to clean up the wiring a lot... just need to make sure it all works first. lol.
thanks for the comments. keep them coming. I want as much input on this as possible.

Really cool.

i have mine on the hot side because it made sence to me and that is also where the stocker is

As far as the BOV goes...What is the pupose of it??
To release pressure from the system to prevent damage to the Turbocharger.....So it makes sense to put it close to the turbo right???
I think it's in the right spot. Or maybe all the thousands of car's I've seen over the years at the track are wrong........LOL.
If you want to mount something next to the TB it should be a PoP off valve......They open while the turbo is at full boost to maintain the preset boost level and prevent boost spikes under WOT...
I see them at the track all the time.
I also see many street cars with no BOV's just wastegates, since that's what controls boost anyway.
You should grind down the welds on the piping and make it all pretty and smooth.....
Other than that it looks okay.
That Intercooler is big, how much HP are you planning on making???

I'll give you an A for the setup. Its not done, so I look forward to seeing the finishing product.
Is that the TRUST/Greddy old FMIC? Seems like you cut the air return outlet and got it rewelded. Am i right?
Get a better radiator and some good ducting for the Vmount setup and it should work fine.
Good luck.

as for grinding down the welds... eh, I don't have the time for that. lol.
and yeah, the intercooler is kinda big... I'm only planning on around maybe 300 at the wheels at most... some day. for now, probably around 270 bhp? or whatever I can get with the stock turbo and megasquirt.

1. Keep the BOV away from the AFM. When the BOV opens, the intake pressure fluctuates, and this causes the AFM To flutter. This can drive the stock ECU crazy and cause all kinds of weird stuff to happen. (originally posted by RETed)
2. Most important; The best place to put is as close to the throttle body as you can manage. This provides the quickest response and is least likely to hurt anything. Remember, when the throttle plates close, the pressure surge starts there. You want it gone ASAP. (originally posted by truespin88)

But putting it closer to the turbo minimize lag. I don't think this guy will boost 30psi so there's no real chance of exploding the TB. Your setup is really cool man, just make sure like others have said before to seal sides as much as possible.

I thought it was there to aid in opening by way of vacuum/ boost pressure from where ever you choose to connect it to....
Am I mistaken on that??

A BOV is to prevent 'compressor surge' of the turbo, not blowing up the TB...

But isn't that why there is a vacuum hose connection on a BOV???

I only say that because I searched around and found several (more) respectable forum members talking about it in an obvious fashion in several different threads...
But we all know it WORKS both ways, so no big deal...

the shock wave is caused by the tb plates closing.... putting the bov by the tb plates dumps this shock wave out without it first surging back through all the pipes and fmic...
fast moving air going in one direction... hits the plates that are now closed.. that air then would have to stop and flow back the other way to vent... then a split second later reverse again when the TB opens again. Im pretty sure its a flow thing.
If it was the turbo causing the shock wave then the ideal place would be by the turbo... but its not.
It will still work where you have it... most people dont care and/or dont know.
that huge *** bov wont have any problem venting what ever you throw at it... the stock turbo dosent flow a crazy amount of air... you shouldnt have a problem.
now im running a t70 and decided to put my bov by the TB... its no where near as loud as it was in the stock spot.... hmm i wonder if thats why.

You want the BOV close to the throttle body to improve boost response between shifts.
Here is why.
When the throttle plates shut and the BOV opens the turbo is still spinning compressing air. If this air can exit closest to the TB the whole air column still has velocity so when you open the throttle plates there is less work for the turbo to do to get the air column back up to speed.
It would be best to have a very free flowing BOV or two at the TB.
If the BOV is closest to the turbo when it opens air will exit the IC and piping toward the turbo causing reversion the turbo will have to fight once the TB opens again...
