Hey everyone,

Noob question. Searched but didn't find what I was after.

Just trying to get some information, why is X BOV better than Y BOV. Why pay, say $400 for one, when you can get one for say $100 (just guestimating prices)

Apart from the sound, what is the difference?

Assuming there is a reason for going better ones, does it only matter if you have a decent amount of HP?

Just curious as when I get my skyline I will be doing FMIC/BOV/DBC.

Cheers

Chris

As people have come to expect form me now I will tell you that the money is better spent elsewhere if you are after performance.

The BOV modification offers NO advantage in performance terms. You will find no one providing you with conclusive dyno or timed improvements. The only test I've come across is a dyno test of various makes including the stock one where by none of the aftermarket units improved power or boost holding at all, no suprises there.

Improvements are made in attracting cops and getting defects however. In terms of improved performance in that area they aren't a waste of money.

Thanks.

I didn't expect a performance gain as such, but my understanding was the BOV will release the pressure (obviously) thus taking load of the system...therefore running a 'safer' system. Especually with high amounts of boost (Which I won't be running anyways)

I always planned to get a plumb back, I am not an attention person, I hate attention... but if u get a plumb back how do you know it is working if u cant hear it?

Still curious about the differences in the different BOVs.

If you want a noise dont bother with a blow off valve and just get a POD Filter. They are loud enough. Also most people are turning away from external venting blow off valves since they are really rice :D

Thanks.

You have a factory BOV, it's a good one. It can hold plenty of boost , more than your proably ever going to run and certainly way more than the factory turbo can throw at it. If you decide to run huge boost 30psi, you can easily modify the BOV to hold it.

you can tell the factory one is working on the stock ecu because your car runs and idles, it's that simple. You will certainly notice if it fails.

There you go money saved. Now you can spend it on something else :D

rev210 - thanks for kinda answering my question.

to the others : i was asking why different BOVs are better...not that i only wanted noise. In fact i want as little noise as possible.

So if anyone knows - I am still curious as to the difference between BOV's other than noise.

If the stock is good enuff, then i will keep it, but still curious about the different BOVs.

Cheers

Whats the point of spinners? there is no point... just rice

As far as i know its to do with the rice factor/sound.. and the amount of pressure they can hold...

but no reason to upgrade stock BOV.

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
