Hks Silent Hipower

[Bazza]

so taking the fact that the original hiper was designed for the is200/Altezza, then by adding backpressure on the silent power model, over and above what the std hiper had, that means that , the action of silencing the sound was by increasing back pressure more than was needed, and by increasing back pressure more than needed you would be also reducing torque low end.

as you said by design the resonator disrupts flow..it does not divert gas flow, for it to divert the gas flow the resonator would need to be open ended, (i.e return to the silencer or exit to atmos)

as it does not, what it in essence does do is scavange away the sound waves or the resonance from the gas flow

the extra resonator works at ist optimum point at low rpm, low speed, low gas velocity

i think we are only guessing the silent hiper is in fact the same as the hiper but with an added resonator !

i personally think it probably is, but i dont believe HKS just stuck a resonator on without testing and maybe making some adjustments

i did say it disrupted the flow, and not diverted it, any disruption in flow will cause a pressure build up however minimal

to be honest in this case i believe it would be very minimal

Chris i think it could be removed and patched up quite easily, but reattaching it might be a bit harder

just never bothered since as im still contemplating selling up if the tax increases go ahead

NO!!!

Everyone is saying this. If you do that, then they have won!

yes but if it does happen i wont be able to afford to run it

that is my main concern because if i do sell the car the exhaust would be sold seperately and i doubt id get as much for it if it wasnt complete
