So this new part would kind of make the stiffer spring obsolete then?

 

Yes, since it can't be used with the new diverter.

 

Chris,

Is Alta planning a new product release and a websiter offering for this DV? Timeframe?

 

We are working on getting this on our website, it'll actually will be up within the next month or so officially.

 

Chris,

What are thoughts/comments regarding the use of your new vacuum contolled DV with the Forge sandwitch atmospheric valve? I will be looking to replace my OEM DV in the near future and currently using the Forge unit which I would like to retain.

 

Have been running this for almost 10 Months now. Still working flawlessly and I am very satisfied with the purchase. I am running a stage 3 map pushing 20psi in winter weather and it has held up with no issues. Would recommend this over either forge or any other BOV/DV on the market. Running this on an Auto MCCS I hold 17-18 PSI when shifting and then right back to 20 but never venting as long as the car is under boost. No compressor surge and a happy turbo.

I would recommend against using it with the Forge BOV, since atmospheric BOVs can cause issues. A recirc style is going to be much more reliable and easier to maintain.

 

Looking forward to reading what Jeff writes on the subject.

 

Hoping to install this tomorrow after I pick up a vacuum hose fitting for the boost tap sensor. Any of you guys have any tips on how to best route the vacuum tubing from the DV to the boost tap (MAP sensor mounted)?

 

Easiet way I found was to route it behind the intake and then under the intake piping to the DV. I used a few Zipties here and there to secure it but for the most part it is just tucked under there and sitting.

 

Wtf I can't find anyone that sells a 1/8 barb fitting that is 1/8 npt to fit this nm engineering boost tap sensor. This little project has become a pain!

 

You can try silicone intakes .com they have a pretty god selection of products

 

Thanks Man ill give them a look. It's always the little things lol! I got the boost sensor from a friend and wasn't even thinking about that part. I should've looked in to it beforehand. I think the Alta sensor comes with one installed. Either way it looks like ill be able to get the tubing on afterall.

 

No problem. It is always something pesky! Yeah the Alta comes prepped and ready. Hopefully you can get it on there soon and let us know your thoughts!

 

Hey folks. Got the DV installed and wow what a difference it's made. I had some fairly annoying lag and this has cleared up just about every little trouble I've had. Well worth the dough.

By the way here is Jeff's blog post about the new CRV: http://blog.perrinperformance.com/author/jeff-perrin/

 

Thanks for the link. A very good read. Sounds like a good part. Do we have a firm timetable for its official release?

 

The part is actually ready right now! To order the BOV, give me a call. We are working on getting it on the website soon.

 

Very cool, Chris. Thanks for posting. There was talk of a resistor earlier . . . Have all the bugs been worked out? Is the design finalized, etc.?

 

The resistor does still have to be used with this. It hasn't given any problems so far.

 

Speaking of the resistor, while mines only been on a week or so I can say its much less of a worry than you'd think. I used some heavy duty electrical tape and wrapped the whole plug several times. I also loosely zip tied the plug (resistor facing upright) to a closeby line to keep it from resting directly on anything extremely hot. This was probably overkill but I figured, why not. The hardest part of the whole install was getting at the plug enough to where you could tape it successfully. Not a big deal though.

I can't recommend this DV enough. It's Leaps and bounds above the stock valve and makes so much more sense than something governed electrically. Less parts to break as well.

Like was mentioned earlier there is a change in the way it sounds when venting over stock, especially if you have an aftermarket intake. I have the DOS installed so I do hear the whistle when the DV vents but its minor and I prefer it. I like to hear exactly what's going on under the hood. It's nice to be able to tell exactly when the valve is open/closed.

 

The ALTA diverter is live on the ALTA website right now! You can find it here: http://www.altaperformance.com/hardt...blow-off-valve

 

So if I have the alta stiffer spring I would have to revert to the oem one?

 

Nope. No stiffer spring, no oem valve. This takes the place of all that. It's a self contained unit.

 

So then this is a much better option to the own bov with stuffer spring? Sorry if this has been asked before I just want to be 100% before I buy it.

 

No problem man I'm with you on the diligence. In a word, yes, this is well worth it. While the spring upgrade is a nice step it only addresses one issue and it still utilizes the subpar OEM diverter valve. This DV takes place of the whole thing and does it far more efficiently.
