how to get a rally style exhaust pop

[bobster1982]

Well I had a rather worrying change of exhaust note today... anything above 3,000 rpm gave me a big rally style backfire popping when i lifted off the throttle . My mate following me saw flames a couple of times :yikes:

got it home and checked the obvious.. found out why it was missing so bad.

engine lovers/servicers look away :frown2:

didnt have much of a tip left on my plugs. Could have parked the car between those gaps!:incazzato:

One set of NGK's later and im away again

You know Rob, sometimes i wonder............................

What how somebody gave me a driving licence and a cougar??

Yep i wonder that at times. :yesnod:

thing is they only got changed 10k ago

Dont tell me........your using bloody NGK's :idea:

I just changed my motorcraft after 50k and they were nowhere near that bad, AND i run LPG

[bobster1982]

I think it was in a former life mate yea

BANG! POP! Whizzzzzzz....Flameout...what did you think you were piloting? a bleeding F14 Tomcat with afterburner? lol

Glad you got it sorted though mate, just wonder why your plugs didn't last very long???...NGK?....think from reading all the threads on here I would opt for Motorcraft

Mines been playing silly buggers just recently, even after i changed plugs, had a good look today and found an open vac pipe..................hopefully sorted now

You could use that as a guage to measure the width of the Suez canal Rob... pretty poor for 10,000 miles really!

I thought the nutter Bobster had fitted a flamer kit then That rally style pop only sounds good on a rally car with anti-lag fitted, sounds like a bloody Ak-47 then
