hey there my fellow skyline enthusiast,

i have a r33 s2 gtst... and it is relatively stock..

however, it had an aftermarket bov which was attached one of the intercooler pipes..

the stock bov was still in place but was blocked off (top hose was cut and a screw put in there)...

i removed the aftermarket bov and put the stock pipe back in to see if there was any difference..

besides getting a little flutter action.. i noticed my car was a bit more responsive.. no change in boost level or anything...

and today i got a spare hose and reconnected the stock bov... my car was current boosted at 9psi..

so went for a drive.. and and gave it a bit of gas and saw my boost gauge hit 15psi... and i it wouldnt rev past like 4500rpm or so... im assuming i hit the fuel cut at boost levels that high...

so my question is... how did reconnecting my stock bov bump up my boost so dramatically?

What he means is the actuator working? It sounds like it isnt because your boosting continually and that seems to be the actuator not responding to whatever limit the boost controller is set to.

Connecting the BOV doesnt effect your boost level, your boost controller does that and if you have not connected it you will just continually boost.

EDIT I just read your last post.... you havent connected the boost controller, it is next to the pwr steering res.

im not running a boost controller man... im using a hks actuator to control my boost... it was set to 9psi before i took out the aftermarket bov... and wen i took the aftermarket bov off and reconnected the stock bov... the boost went up past 15psi... i dont have the boost solenoid either... just actuator to intercooler pipe..

i have readjusted my actuator to 10psi now... boost comes on much earlier now.. and kicks in harder..

just weird how it jumped up so dramatically...

The std bovs are quite good. Block the little bleeder hole in them and they work as well as a tight 'good' aftermarket.

I blocked my std bov off some time ago as I don't see the need for one + I prefer the slight dose noise over an airy whosh bov sound.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
