系咪你个涡轮太细？你装既几多号？作者: chrissyong 時間: 2010-9-7 01:41 AM
your car got blow off valve or not?or your car boost too low,like 0.3 or 0.4 bar,sure not blow off sound,u try up boost like 0.7bar or 1bar,sure got sound,but must tune your ecu for safe air fuel ratio like 10.1 if your engine internal still stock作者: huit 時間: 2010-9-12 01:54 AM
Or if you don't want to do something drastic like messing with the boost pressure (most people dial up the boost pressure to go faster and not to make noise), and all you want to achieve is louder noise, get a riceboy style BOV with a trumpet attached to the nozzle to amplify the sound (Blitz makes some good ones), or relocate the BOV closer to the turbo so there's less pressure drop, or relocate it closer to the outside of the engine bay so the sound deadening material under the bonnet won't muffle the noise (eg near the intercooler)
While a higher boost pressure will definitely result in louder noise as the BOV discharges - you cannot say categorically 0.3-0.4 bar would produce inaudible blow-off noise - there are too many factors involved.
But first of all, you need to establish whether you car has a BOV at all - most cars come from the factory with a bypass valve that vents the charged air back to the intake, because in most jurisdictions BOVs are illegal.作者: atomu28 時間: 2011-8-22 07:32 AM

放气声有好多原因
PSI高同低..出既声又唔一样
