BOVs are used for the following reasons (if my googling can be trusted);

- prevent compressor surge

- reduce turbo and engine wear

- maintain turbo speed during gear change (to reduce lag)

What he said.

There is no benefits of running a aftermarket blow off valve unless your running really high boost. Just retain your stock one. Going by your username if you have a GTR, GTR BOV's are really good and more then sufficient.

i think he's asking the pros and cons of with or without a bov, not whether if it's aftermarket or not.

Well the only pro of not running a BOV would be less weight, less piping.

Hardly see those as any gains to be had.

Not going to debate the effects of turbo damage from lack of BOV. That is another topic.

Basically, I'm just going to say there is no real benefit in removing the BOV. Just make sure if you have one that it is a plumb back.

Lets consider for a minute the fact that most race cars don't run a BOV.

Lets consider for a minute the ONLY reason they were created was for emmisions reasons.

Lets consider for a minute the only people who started spouting about engine wear and turbo wear were the manufacturers of aftermarket BOVs...

The only thing they will do is remove "dose" (Which is perfectly fine, non damaging and doesn't slow the compressor down)

I run a MASSIVE fark off turbo, laggy as hell, and between shifts, it comes snapping back on full boost. The real way to setup a wastegate will prevent lag between shifts from not running a BOV... :blush:

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
