What does pinging sound like?

[SICKM]

In every car That has ever come off the dyno when it is taken on the street, the only way to be certan that there was no pinging was to do it with the widows up. You can hear it 100 times better, and notice things that you could not here with the windows down. Another way is to stand on the road and listen as the car is comming towards you. Cover both you ears with you fingers, sounds stupid but it works. Doing this blocks out all the back ground noise. Try it!

I Fitted a loud exhaust and mine went away :D

Actually I've been worried about mine lately

It makes a pinging type sound only low revs + load... Doesn't have any issues top end, Although it seems to be more noticable when cold.

The car is going in for a dyno in the next week or two so I will have to ask em what they think...

I agree with SICKM, it is often easier to hear with the windows up, and the blocking the ears thing is proved by the fact that on a dyno, often the dude who is listening for pinging with his head in the engine bay does so while wearing ear muffs! Not so much for the volume of the engine as for making the sound of the pinging stand out more.

Tex, one thing I have also found is that i was able to hear pinging the best when i was standing a good 25-30 meters away from the car when itr was on the dyno and blocking my ears, also helps if you are looking away from the car as it does not distract you! lol

Jesus! Must have been some pinging!

I have found tat if there are lots of reflective surfaces around, such as brick walls etc. I can hear pinging quite well with windows down, though I think this works best if the pinging is a particularly harsh metallic sound, as it is with my car...

My colt (which ran out of rego and went to car heaven yesterday) was the ping-o-master, and yet still ran for 2 years (couldn't be bothered getting my hands dirty and winding back the timing).

You could hear it from about 100 metres away. Sounded like ball bearings dropping into a flying pan It was worst at low revs when you put some load on it (ie, going up hills). If you revved it out, it was usually ok though.

LOL Rhys!

Hey I just had an idea, Fook, would it help if I went out and made a wav of my car pinging its tits off? :D I'll send you the bill for the rebuild! :p

Hmm, strange when I drive in a tunnel or next to a wall or something I can hear a sort of metallic rattling, but I think that's just the engine rattling, cause it's all the time, not just under load etc... and it sounded like that even when the ignition was wound back to +0...

Someone else who has an old Corolla just emailed me, he's running +35 degrees ignition... :D

i used to run about 40 on mine thats a guess cause it was well off the timing marks!! i found from 30 to 40 tho there was bugger all difference, so i left it on 30, it didnt ping but it had a huge cam, heaps of head work and big carbi.
