sideexitsupra Posted April 24, 2011 Share Posted April 24, 2011 Whilst out enjoying the sunny weather today suffered a strange incident. Not happened before. I have a TT6 which is BPU with a Greddy Profec II boost controller and a fcd. Anyway, in low boost setting, about 1.1 bar was pulling in 5th. 2nd tubby came in very late at just over 5000 rpm and at 5500(ish) there was a loud bang and loss of power. My first thought was I must have popped a hose somewhere. Everything seemed fine immediately afterwards so switched to high boost and did a pull in 3rd and all was just as manic as normal! Checked hoses and all seem as they should be. Limiter has also been removed so we can rule that out. Anyone shed any light on what might have caused this?

DaveR Posted April 25, 2011 Share Posted April 25, 2011 No idea about the cause, but if that had happened to me I'd be straight into the in-tray of a tuning house somewhere to get it looked at (post bank holiday, of course...). Quote Link to comment Share on other sites More sharing options...
sideexitsupra Posted April 25, 2011 Author Share Posted April 25, 2011 Been perfectly fine since and no warning lights at the time so not too worried. Will call Whiffin tomorrow if no explanation by then. Quote Link to comment Share on other sites More sharing options...
Nic Posted April 26, 2011 Share Posted April 26, 2011 (edited) Back fires are usually caused by unburnt fuel in the exhaust, maybe a result of the 2nd turbo coming in late, worn plug(s), broken coil pack connector(s), etc. If it's working okay now I'd just monitor it over the next few days to see if all is working as it should.

Thanks Nic. Wasn't a backfire though. My description of a bang may have been inaccurate. More of a loud thud. Not had chance to call Mr Whifbitz today, might send him a text now.
