Absolutely no issues, this simply replaces the bosche unit. I will post photos of both so you see the difference.

It doesnt run rich or anything at all? I was told by another local stillen sc guy who has the turbosmart bpv that he had to
recirculate it back in cuz it was messing with the car. Told me
venting to the atmosphere was causing issues since the mafs thought there was more air in their than normally. Maybe if u can tune for it it would be fine? Cuz i love the bov noise

My tuner said this was the highest HP Stillen SC setup that he has done yet so I guess that was a good sign everything was working perfectly. If their was an issue i'm sure HPLOGIC would have told me or advised to use the one that came with the Stillen SC. Kyle Millen has this exact same unit in their own 370Z and that was why I got it.

The new MAF connections also remove potential bugs with extending the wires on previous kits because of the potential resistance differences in splicing them. This was a great solution Stillen came up with and very happy I had these in time for the install. HPLOGIC was about to splice the oem maf wires and run these longer extensions just to hook up the MAF but with the new connections provided we were able to simply plug and play.

Yep I got the wrong one.

I vented mine too, runs actually better now at idle, The weakest setting it would idle at 12.1-12.8, I set it in the middle. Runs really good. My car would go from 13.9 -14.8, kinda jump around, now it doesn't stray from 14.4 -14.8. It sounds really good under high load. Im happy with it! When the setting was to stiff, it would almost shutter the bypass valve, and almost surge back towards the blower, I could clearly hear it. I loosened mine up and that went away.

Hey Diego, I'm glad you are enjoying the car! Can't wait to hear more about it!

The BOV will make the car run rich on decel. As you mention, because we use a draw through setup the car's ECU has measured and is therefore expecting the air to be entering the engine. However, as the air is not there it will run rich.

With that being said, we've been running blow off valves on draw through MAF vehicles for over 20 years. I've only seen it cause an issue when the BOV isn't set correctly and is overly sensitive and if you're cruising slowly through a parking lot or something. It could open and cause the car to stumble and possibly stall...again this only occurs at low speed. But we've been running these dual pass BOV's on our GT R builds and as Diego pointed out, our Z currently has this BOV on it as we continue with some more testing.

Also, just to clarify, the shields in Diego's kit have been in all of the G kits since we began production. The Z uses a different shield but it too has been in there since we began production. These shields protect the intake/filters but also help to clean-up the air flow before the air enters the intake path.

Hey Kyle

Thanks for the clarification :tiphat:

Ahh i gotcha that makes sense. Kyle can that be tuned to where on decel the ecu can know that theres less air than it thinks? I would imagine if it could stall in a parking lot it could stall in traffic too

I re-read my post and realized it wasn't very clear. Sorry for the confusion. What I should have said is that if the BOV isn't setup correctly, and you are traveling at low speed such as in a parking lot you might experience a stalling or stumbling. However, this is only if the BOV isn't properly setup.

With that being said, the great thing about the Turbosmart BOV is that it's a dual port. So if you're just cruising through the parking lot it's actually still recirculating. It only vents to atmosphere when there is sufficient pressure to open the valve further so that it reaches the next level.

So since you are here Kyle, does this BOV indeed hold more boost then the Bosh unit?

?
Is the spring that comes with the TurboSmart sufficient?

There are a couple of answers to this question.

1) We have not experienced any issues with the Bosch units holding pressure. Keep in mind that this is still a relatively low pressure system compared to other O.E. applications running the same Bosch unit at higher pressures.

2) Our standard kit no longer uses the Bosch by-pass valve as we purchase these from Vortech and Vortech now offers a very nice, all aluminum by-pass valve. We have switched to the new Vortech unit. There is nothing wrong with the Bosch units, it's just a running production change that Vortech made, and we made as well.

From our experience yes, it's sufficient. There are instructions that come with the TurboSmart BOV on how to dial it in but basically you adjust the body of the BOV which in turn adjusts the internal spring pressure. It's pretty easy to do really.

So far with 350 miles on the car with the Turbosmart BOV, I only have noticed how good she sounds :) I love everyone's reaction when they hear it lol.

Hey Diego,
I'm really happy you enjoying. I will be going down this road again soon with my sedan, Just need to save some $$ just incase it my bad luck happens again

Can't wait man. Will you do the same mods to the Stillen SC again?

I gotta install my new Clutch/Flywheel/CSC but will wait till the OEM gives out. Surprisingly it feels great for the type of daily driving I do.

I will for sure do the heat exchanger and Bypass valve. But not sure about the other ones .

What did you do to the heat exchanger?

I replaced the Stillen one with a front mount one from Frozzenboost.com.

There are a few guys on here that started running it after me . IVO(swiss370Z ) has done a great job on his he wrapped his hoses also.

linky :)

Air to Water Heat Exchanger

Hmmmm interesting!

Yeah mine came in a couple days ago! Just need to figure out the lines and im waiting for mocool to arrive.

You'll like it and its going to LOOK good,. only thing is you have to turn your crash bar upside down, LOL , Was different for my( G37) I only had to cut my tow hook off. :tup:

LOL Who needs a toe hook anyway :tup:

What's your plan if you ever need to tow it? There isn't much besides the tow hook I would want anyone hooking up to!

That's what flat beds are for man LOL, They can use the sub frame to get the car on the flat bed, Trust me I know had my coupe towed 7 times before it was all washed up :icon14:

Sorry I was being sarcastic. I would not want to eliminate the toe hook.

I guess I was thinking more about at the track, I don't think they would take the time to do that. I remember reading in the NASA rules that if you don't have a tow hook they hook up to whatever they can to get you off the track the fastest.

I bought this one off ebay, Air to Water Intercooler Aluminum Liquid Heat Exchanger | eBay

Dropped my coolant temps by20-30 degrees, no lie.
I also rapped my coolant tank in heat rap, aswell as the coolant lines. Great mod for 150 bucks and its very noticeable.

On Saturday i can Report
The BOV is now in my Country and on the way to my home :icon18::icon18:

Sweeeet!!! Looks nicely packaged. What size does it need to b to work with our kits?

Kompact Plumb Back-25mm

:tup:

By the way, you don't NEED a front tow hook. I can't access mine because the front bumper mesh is in the way. No problems with towing the car. Just use a soft strap when towing the car and tow using the front lower control arms. I've done it plenty of times with no issues whatsoever getting my car onto a flat bed. I don't drive my Z as it's a show car/trailer queen LOL. :ugh2:

Goes right on. Plug and play

If any one wants the plumb back version please hit me up ridiculous deal. If you look under the vehicle in the wheel well there are holes on the frame for actual hooks to hook up to.

Mmmmmmmm Aussie made goodness!

(Probably made in China actually but at least its an Aussie company :P)

Any updated vids with the dual port at idle and running thru the gears?

^My tuner was not able to run a 50/50 vent to atmosphere with the Stillen SC and Turbosmart Kompact dual port. The venting created issues with the tune and driveability. It's set to fully re-circulate. No pshhhhhh sounds. :( Car runs great though.

EVOHUNTER, did you need to get your ECU re-tuned or did you just tinker with the knob on the top of the BPV until it was venting and idle was OK.

Doesn't the BPV suck in unfiltered air as well?

For us guys still on full re-circ, any tips for how to set venting to atmosphere and re-circulation? Do you just go half way on the top of the bpv, rev the motor, and repeat until it idles OK, AFR are stable and no stalling?

At what RPM should the BPV vent to atmosphere?

At what PSI should the bpv vent to atmosphere? Should we

Just a thought, could you not run a twin piston dump valve? That would stop the idle/stall issues and vent to atmosphere. Something like a r-spec type B or an HKS SSQV.
