What Does Engine Detonation Sound Like?

[DuFFR32]

Might sound like like a silly question but without a detonation or knock sensor how can you tell if your engine is detonating?

Curious because not sure how much a standard internal RB20 can take before breaking conrods n big ends

[R31Nismoid]

everyone has a different description.

It can sound like small stones on a tin roof, or stones kicking up under the guards.

To tell - ask your tuner.

Stock RB20 innards will easily run 260rwkw day in day out.

Nails being shaken voilently in a paintbucket is another way to describe the noise, I've never heard a RB engine detonate though.. which I hope is a good thing.

Car needs tune atm the guy i bought it off had it tuned by PITS in Qld anyone know who they are?

Apparently got 220RWKW at 16PSI

I need to get it tuned, how much boost is this setup capable of?

How long is a piece of string?

It really sounds like you need to go and talk to a tuner mate, just drive it very easy until then if you are worried.

How long is a piece of string?

Twice the distance from the middle to the end.

I always thought detonation sounded like an olllld diesel hehe. Its not a nice sound, so if it does it, youl know.

Try taking off up a steep hill in 2nd. tickticktick

Just remember that if you can hear the detonation, it's already too late - the damage has been done.

If detonation sounds that bad then ive not noticed it yet thank god. I dont have a tuner yet I live in Nothern NSW On the beach there isnt any good tuner shops here i was thinking of taking it to mercury motorsport for a nistune until i can save for a Power FC or whatever

[Strik3r]

PITS are very good. If they did the tune, the car is probably fine.

yeh matt spry is claimed one of the best in QLD so u should be fine unless things have been changed since the tune.. are u askin about the sound cause u can hear it or your just worried? doesnt it feel fast?

just tryin to figure out the reason of the question

Sounds like good news to me! The only problem with the car is its running pretty rich (it chews the fuel) and black soot covers the rear bar lol Other than that is the broken exhaust manifold stud which im about to try fix which i guess caused a bit of surge hard on the gas in 3rd or 4th

About detonation was just curious as to how much boost I could run with this setup, its pretty happy on 14psi which is fairly close to 1 bar right? (my boost guage is in BAR not psi) would 18 psi be ok you think? the guy i bought it off said 18psi is pretty fun haha
