Ignition Questions. Anybody with boost.

[phoenix64]

I'm just wondering who is running modified or stock ignition, and what your experence has been.

My problem is that the richer I run the car, the more timing I can run, but the more it missfires. Any thoughts/suggestions appreciated.

TR6's ?

Your car is intercooled. You can get away without the TR6 but you do have to lean up a bit.

I just came from American Muscle Installation. There's a SC Mustang over there that was running so rich that flame and black smoke is actually coming out of pipe. It made me think of Fast and Furious. I'm not kidding either. The car does stall at idle.

For us without an intercooler the rule is dial one for every 3 psi of boost.

Thanks for the advice, I'm already running TR6's.

I'm not that rich, my max timing is achived at about 11.5:1, but it missfires. I guess I'll just replace the wires, and plugs again.

what gap do you have on the plugs?

the longer the gap the more chance there is that high compression will blow out the spark.

I have been fine at 6 psi and .035 gap on the old tr6's.

My plugs are gapped at .035.

I found some info that explains why I can run more timing with a richer mixture. Turns out that your better off with a lean mixture, and more retarded timing anyways. At least as far as power goes.
