Little fire in my airbox

Hello viewers,

After running a little rough for 2 days, idle unexpectedly dropped from 800 to 500 and stalled between gear changes, one back fire through the air box and hey presto!

I took the air box off to give it a tune and was confronted with this....could have been catastrophic!

Gave her a tune and now running better than ever. I still this car and engine. FYI

Yes, I think I will invest in an appropriate fire extinguisher. Then wait for a hole to melt in the bonnet and put out the flames.

That was lucky. Good thing to have a fire exstinguisher handy. Got mine from Halfords £20.

Time for an ACT air box.

I found exactly the same thing on my air filter, well rather RG did last week while checking the car over and doing the clutch. Same cylinder too I think, not sure on cause either, but a bit worrying..

WOW... lucky the harmonic balancer didn't melt too.

Would the same thing have happened if you had a Griff motor instead of a S6??.

Andy, when the TB's fall out of tune they get a little back fire action happening just within the TB it's self. And also the spray oil you apply to the filter is highly flammable as well. The clearances are were fine, she just wanted a tune.
