high compression timing advance, how many degrees?

[mackdaddy240]

Ok I've been playing with my timing for a while now trying to find the best setting. The compression is 10.6:1 and I'm running 93 octane, It seems to run pretty good at about 25 degrees. I'm just curious as to what other high compression kas are running.

I run about the same. What plugs are you using and what are the gapped at?

[mackdaddy240]

Well, when i run N20 I use the zex plugs that are pretty cold, but usually I just use regular bosch platinums that are spaced for a stock ka, I'm not sure exactly, I've never measured them. But I am using a msd digital 6 plus, and a msd blaster 2 coil so it fires twice instead of just once under 3,000 rpm.

OK so I am not familiar with Bosch plug numbers because I am not a fan. I use either NGK or Champion in the race car. It has more compression but about the same timing. I run them 2 steps colder than stock on the NGK or the champion. We also found that with more compression the engine likes a little tighter Gap than stock. We closed them up to .030 and found the best performance there.

You mean tighter gap for less detonation/ more advanced timing, or more hp?

And are you talking about retarding the cams?

Mackdaddy420 i too am looking for LSD, i have been tripping on shroomslately and plan to grow some.

More Hp and drivability

I'm talking about turning the distributor to adjust the timing. And its mackdaddy240, although shrooms do sound pretty good
