Blow-Off Valve installed !!

you will get used to it. i've noticed that changing from 1st to 2nd, you will only get a noise if you give it a bit, and change gears at around 3000-3500 rpm. from then, changing from 2nd to 3rd, and 3rd to 4th, to get the loudest noise, it is best to give it a bit of throttle and change at around 3000-3500rpm. at the engine heats up, so will the bov, and the springs will loosen = louder sound again.

Personally, my bov is bloody loud, it is not really a good example in the video and i wish i had a better camera, but my gf clearly hears me coming from well down the street and around the corner.

are you sure it has been put on the right way...one of my mates put one on his Ralliart Colt a few months back and had it on the wrong way for about a month before someone said something. when on the wrong way, your car will flutter softly = not good!

have a bitof a drive around doing as i said and see how you go. you should be driving for at least 7-10 mins before you get the most out of it.

You will not damage your turbo by not running a blow off valve. Period. Whether it is bush bearing or ball bearing doesn't matter. The weight of the air in the intake is 2/5 of **** all and will not in any way be enough to damage the bearings or anything else in the turbo. Blow off valves were made for 2 reasons:

1. To reduce noise - new car buyers don't like a car that makes a weird fluttering noise.

2. For emissions compliance on maf sensored cars - with an atmo bov or no bov the air that has passed the maf does not enter the engine, causing the car to run rich and fail emissions.

No bov causing damage to a turbo is an old wives tale and is NOT true. Many many street and race cars have run very high boost pressures with no bov for long periods of time with no negative effects. Bovs do NOT increase performance and they are NOT required to prevent damage to a turbo. On a maf sensored car the car will run poorly on gearchanges without a plumb back bov, on a map sensored car they serve no purpose other than noise suppression which obviously isn't relevant with an atmo valve. Atmo bovs are just a good source of boost leaks and wanky sounds, nothing more.

You forgot the 3rd reason BOV's are employed...To prevent compressor stall from the surge of compressed air being redirected against the turbo compressor turbine when the throttle butterfly is snapped shut. This prevents turbo lag when the throttle is opened again, so in a sense, they do help with performance, by allowing better throttle response. Blow off valves will help on any turbo'ed car(except diesels, most of which don't use throttle butterflies). The sound may be wanky, but I like it...Did you ever hear a Audi Quattero S1 Rally Cars BOV?? That sounded the business!!!

Im not saying i dislike BOV / Flutters.
It is a wanky noise. Why have a atmo one when you can have it plumbed back into the system? Because you want a wanky noise...
I was just saying that it doesn't cause damage like everyone says it does.

[Kai]

o and btw.

I have no bov.

All the lines are blocked. Have been since day 10. Havent had a problem and have 0 shaft play for anyone that says i will have heaps...

I find that the car feels better in between gear changes aswell without it on there.

where can i pick up one of these for cheap? ive rang autobarn and they quoted me $320... i looked on ebay the same price but i have to pay 10 dollars extra for shipping.. any other options?

He's the guy for that ! Especially about Forge Motorsport in this case...

They are required, you are wrong and if you keep your car for a while you'll be eating your words.

Hahahahaha...this was a long and drawn out argument in another tread also...We firmly established that a BOV/Diverter Valve was required on petrol driven turbo cars.

Dose pipe the only way to do it..
