I know I have probably missed this somewhere along the line but...
Why and how does my jap MY95 WRX "pop" and is it harmful? (to the car that is!) Thanx in advance Knowlsey |
Knowlsey, the pop could be over fuelling. Do you have a complete de-cat system?
It is common for a scob to over fuel, not much to worry about. Dan |
mine has started doing this have just put on a magnex centre decat system other than that it runs fine i think the popping sounds cool :-)nothing to worry about
mark |
Popping can also be underfueling - if the high rpm/low load part of the map is weak, when 'removing foot from pedal' at high rpm there isn't enough fuel to light in the chamber but enough to ignite in the exhaust!
Anyway, most people worry when their car isn't popping :D |
Thanks lads,
now how can I make the popping louder? |
Take off the backbox will make it louder ;) Louder exhaust = louder popping. Strnagely enough, the loudest system I have heard of was fitted by your namesake from scoobysport.
