i read an forum in option mag. actually it can be done.... but you need a BOV also... but you got to change the spring stiffness to be softer so it can trigger without so much of pressure.... the detail i donno how to build lah.... just share this out.... maybe other ppl can help...

last time.. our DIY king Johnson Lam got teach...

things needed:
1. car alarm siren
2. a small cheap car amp
3. key chain recorder

1st... bypass de circuit inside de siren and connect 2 wires directly to de speaker.. then for de "PISSHH" sound.. get use de key chain recorder to record de sound from our mouth(easier mah)
connect it to de amp and then to de speaker...

how to trigger it is a problem... i remembered Johnson said using some sort of pressure switch.. or u can trigger it manually lar.. hahaha

anyway.. happy trying! :)

the spring is something like the control... once the pressure reach the set limit it will realease the pressure loh....
correct me if i'm wrong.... mayne turbo car owner should know better than me....
