Guest Deano2440 Posted April 18, 2012 Share Posted April 18, 2012 - at approx 1:39 when the acceleration starts, i notice the HUGE air compression sound from the supra, i have noticed this with a couple that i have watched on youtube...and only ever heard from a supra, could someone enlighten me on what makes this wonderful noise?(turbo i am guessing? if so what type!?) second question...on other videos there seems to be a 'spiraling' noise when the gear is changed...what is that!?? thanks people! (p.s i do not intend on promoting illegal road racing from the above clip...it was the best one for sound purposes) Quote Link to comment Share on other sites More sharing options...

Noz Posted April 18, 2012 Share Posted April 18, 2012 Sounds like external wastegate noise to me. Compressor surge between gear shifts may cause that `spiral` noise you refer to, though I can't actually hear any turbo noise due to camera being outside the car during the filming.

Guigsy Posted April 18, 2012 Share Posted April 18, 2012 sounds like a screamer pipe (externaly vented wastegate) to me. Quote Link to comment Share on other sites More sharing options...

add heywood Posted April 20, 2012 Share Posted April 20, 2012 The noise is because he probably has a turbo the size of a dinner plate under the bonnet Quote Link to comment Share on other sites More sharing options...
davis6110 Posted April 20, 2012 Share Posted April 20, 2012 In the description is the clue :-) Toyota Supra: 6765 billet wheel turbo, HKS 264 cams, AEM, E85, ~700 rwhp Quote Link to comment Share on other sites More sharing options...
