I have tried installing HKS BOV's onto my car. All together i have tried putting in 3 of them. Each of them stall my engine. Which means there is sumfin funny goin on wif my car. People say that my car is too modified to put one in but i think that is complete crap. I have got many mods, some people say that it is my Fuel/Air ratio is stuffed. Since the Stock BOV is a plumback and the HKS is an atmosphere BOV people tell me that there is not enough air goin back and the engine then puts in more fuel which stalls my engine. Does that make sense? Ive also heard that i can buy some sort of a Idle Restrictor from HKS that wont allow the RPM to drop and stall the engine. Ideas please.

Thankz

Chris

Your friends are correct. When the BOV vents your car will run very rich, so rich that it will stall.

Sell the BOV and stay with the stock one, if your really keen you can do the mod to it that is on this site (do a search).

Either that or buy a plumb back one.

There are little add on electrical things that can solve the stalling, plus a S-AFC will fix it too. But your money is best spent somewhere else.

nuh the think is i didnt buy it, First the guy installed it, then we went for a drive and it stalled, then he put in a second one, also stalled, Its not a tunning problem. He tried everything. So at the end i just put back the Stock one. So now my money is going towards a Apexi Boost Controller :)

I assume the vacuum hose was connected to the HKS BOV?

If it wasn't that would make it still for sure...

Even the stock BOV will stall the car if its not plumbed back! I tested the stock one vented in my car, return pipe blocked, Bov vented, vacuum hose connected = drives for a while ok, then HALT!!! Nothing :D

yea it was all connected correctly. The stupid thing was that the person who had the car before me was driving it with a HKS BOV. How dangerious is that if you are on a round about when u have to go slow and your engine goes off. Brakes and power steering are gone. Dont know how he was driving it. Plus it wrecks the Clutch 100 times quicker. I staying with the Stock BOV and saving up for a APEXi Power FC. Damn i wish i had a money tree :)

i have the same problem with mine i got HKS ssqv. skylines seem to have alot of problems with BOVs the vent to much pressure out causing the car to stall.

the only BOV that i have been told that does the trick and doesnt stall are turbosmart ones, but my friend has blitz one and is does it very rarely.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
