A few people have expressed they believe nitrous backfires they have had (on all make kits) to be linked to running wasted spark coilpack ignition.


The theory is that the spark which occurs on the waste cylinder can ignite the charge in the inlet.


My own view (and experience of DIS cars running wasted spark) is that this is not a risk, but i would be interested to here the views of others?


Surely if this WAS a risk it would be a risk on any car running batchfire injectors and wasted spark as they would also risk ignition of the fuel on the wasted cylinder?

If anything i would propose that the prescense of nitrous to cool the inlet would make it less like to happen?



Your views/experience/opinions please????
