Timing

[Dookie]

For a long time, my car has been a slow piece of crap. Slower than a bone stock automatic 240. A couple days ago I checked my timing and it was at around 17 degrees, so I bumped it to 22, Im running 87 octane and the car runs awesome. Im not sure what a detonation sounds like, but is it safe to run 22 degrees timing on 87? I wanna keep it this way, an actual quick car now.

22 is just fine.. you should be running a higher octane anyways.. its good for you... kinda like milk.. stock timing is 20+- 2 deg.. so 22 is cool

Thanks, I just didnt really think 5 degrees of timing would actually give me that much power, the car feels alot better now.

bah lol thats me in that post above

I would run higher octane, it's 10 million degrees right now and your ECU will trim the injectors to run leaner with the hot weather.

put 89 in the other day, btw alan, what does a detonation sound like?

[left channel audio]

it sounds like the valves are "clattering"

best explanation i ever heard was a cann full of BBs rattling. and every time i ever heard it, it was much easier to hear with the windows rolled up. ive never ever heard my 240 detonate though, its a lot harder to hear on four cylinders too.... but i only ran 93 until a week ago when they ditched it

It sounds like a bad gasket, real airy sounding but a little tick.

I thought it sounded like a ping?

So on a 95 would it be safe to run 22 degrees or higher and im already using 93?

If it sounds like that, then Im not getting any detonation. There is this wirry sound though, like Im about to get a bad pulley bearing, I dont know if I had it, I guess I havent really checked for noises besides the usual timing chain slap.
