Spark & It's Effect On Low End Torque

[Stanger007]

Guys, I really got a lot out of "How to Build High-Performance Ignition Systems", not a bad read for someone really wanting the nitty gritty on all aspects of ignition systems.

It's worth checking out!

You know a place on the web where I can get a .pdf of that for free?

But seriously...I'm gonna look into that.

It would be nice if someone that had a tweecer could dyno their car with the stock timing tables and then loaded their customized timing tables in to see what the differences is. I personally feel like there is a pretty good difference in the lower rpm torque. With my car being mostly stock the only differences I've made so far is timing and I think the only gains I made were in the low rpm's. if I can ever get to the dyno I will try it just to see

Nice topic...

I have a N/A "stick" question?

when having all the timing in by 2500 or so to full advance do you smooth out the sub 2500 to make it less of a drastic jump? Anyone have any issues from that drastic jump?

Second, has anyone tested (dyno or track) with say 34-36* from 2400 to 4k and then 33-35* or so at 5k and up. Vise versa?

In the winter ... I usually go up to 36

grady, i basically copied you spark table, but with a max of 30, and the next row below added around 2 deg throughput. and wow...felt like a new car at wot to me for some reason....pulled pretty hard.

You moved away from your forced combo ... did you not

If so ... why the conservative value of 30

I got the most power with my self ported E7's at 36
and
fuel at just below 13 to 1
and
running 93 grade gas
