JamesF Posted July 16, 2005 Posted July 16, 2005 Just wondering how the WRC cars have a really chirpy wastegate and what you would have to do to get a road car to sound similar ?
spooks Posted July 16, 2005 Posted July 16, 2005 You can do it but external wastegate/ no dump valve and many many turbo changes would be called for so its not advisable.......... gotta love the noise they make though Spooks
Johnny50 Posted July 16, 2005 Posted July 16, 2005 Really wish i knew how to get the sound... But going by the fact that nobody else has the sound... Tenner says it wouldnt be a cheap mod !!
dougster Posted July 16, 2005 Posted July 16, 2005 I got it a little bit when I ran my standard airbox with ITG panel filter, standard DV but with the resonator in the inner wing removed!!!!!
st3ph3n Posted July 16, 2005 Posted July 16, 2005 Correct me if I'm completely wrong, but isn't the chirp to do with the anti-lag? So perhaps some sort of anti-lag system is in order. Not cheap I imagine.
the squiggle Posted July 16, 2005 Posted July 16, 2005 Had the WRC style chirp for over a year now To obtain WRC style chirp requires you to remove all of the dump valve components and blank off the openings. The TD05 turbo fitted to the early cars can handle the stress of the turbo spinning back and forth very quickly when you lift off the throttle. The IHI series of turbos were a bit more fragile in the main shaft dept and are not suited to non dump valve spec. I now need to fit a std recirc as i have replaced the TD with a VF28 so no more chirp for me... Grant
Johnny50 Posted July 16, 2005 Posted July 16, 2005 Dont think it`s Antilag. I had Anti-lag on mine, along with other mods, and it never made that noise. Although, i had an HKS SSQV, and it was close the the noise sometimes. I had ALS setup, and it produced 1bar of boost at tickover when switched on.
st3ph3n Posted July 16, 2005 Posted July 16, 2005 Thanks Johnny, I have learned something, and on a saturday too!
Johnny50 Posted July 16, 2005 Posted July 16, 2005 PMSL... Just dont tell anyone you learned from me... lol
higgy Posted July 17, 2005 Posted July 17, 2005 correct me if im wrong here but is the chirpy noise not the tubo stalling ,wich would result in turbo lag Just a thaught. Higgy
JamesF Posted July 17, 2005 Author Posted July 17, 2005 Thanks Scott, everyone, for your input. I didn't think it would be cheap (ha, no pun intended ) as the amount of design and technology that goes into a WRC car is phenomonal. If you don't ask though.....
