what EXACTLY is detonation?
 

I am hearing a LOUD "pop" sound. However, ir's not coming from the motor, but rather from the DP, right inder neath the shifter it seems...it only happens after I hit low boost, and let of the throttle. could this sound be just an obnoxious backfire due to running a little rich? or is it detonation?

Re:what EXACTLY is detonation?
 

no thats fine.

my car does that same pop when i downshift sometimes.

also detonation is when the fuel explodes instead of burning in the cylinder.

Re:what EXACTLY is detonation?
 

where would the fuel explode during the detonating??

pingin sounds kinda like a peice of metal getting hit by something moving/spinning, at least it does on my car. more of a tinging sound

Re:what EXACTLY is detonation?
 

Pssst... hey buddy, In the cylinder... but shortyz meant that instead of a controled burn, it burns/explodes at the wrong time, usually before the piston reaches TDC. That causes alot of stress on the piston and rods, causing a blown motor...

ahhh i see..thank you.

whats the best way to prevent detonation? retard the timing?

Re:what EXACTLY is detonation?
 

retard timing, have good quelch areas, lowering compression, using higher octane gas.

Re:what EXACTLY is detonation?
 

Yeah, definately retarding timing, good fuel management, and plenty of tuning will all help prevent detonation.

oh yeah... how can you tell if you're detonating? I don't think i've ever had it happen before so i'm not sure.
