Dblock Posted December 4, 2011 Share Posted December 4, 2011 If its not leaking 100% then its the decats that give you the hiss. Quote Link to comment Share on other sites More sharing options...

Dblock Posted December 4, 2011 Share Posted December 4, 2011 Sounds like a turbo hiss,is that the decats then ? Most likely as long as it isnt leaking. Quote Link to comment Share on other sites More sharing options...

The G Man Posted December 4, 2011 Share Posted December 4, 2011 HFC's do it in gear, out of gear, they do it on the over run, I imagine decats are the same, nothing to do with gears. Quote Link to comment Share on other sites More sharing options...

Decats hiss on the way down from the rev, and in gear it never drops like that. Hence why it doesnt do it in gear. HFC's only do it slighlty.

That's nearly right, it's called the over run, nowt to do with in/out of gear, Berks do it all the time, in neutral as it drops revs, in gear as it drops revs, over run. Again I imagine the decats are the same Quote Link to comment Share on other sites More sharing options...
Dblock Posted December 4, 2011 Share Posted December 4, 2011 My car never did that in gear though. Hissing was only ever heard on the over run whilst not in gear. Never really did it with the HFC's. Quote Link to comment Share on other sites More sharing options...
GT4 Zed Posted December 5, 2011 Share Posted December 5, 2011 Decats all the way and also the bungs on the K1. Took me ages and countless gaskets, bolts and torging of exhaust bolts to finally realise this At the Ring car park lot's of pips still belive my car is turbo'ed and i'm lying when i say its not Quote Link to comment Share on other sites More sharing options...
