So who's running a Comp XE268?!
I have a manual trans.If you run too much initial with a big cam 223 to 292 in mine, and lots of cylinder pressure,with a manual, then at low rpm,it tends to get jumpy; like an 80s Mustang. And with a manual trans, the engine is sorta married to the tires.
So to cure the bucking I run 12 to 14 initial,
and it doesn't start advancing until 1000 rpm.
I have a two stage curve using one spring with a long loop; so the first stage hustles up to
~28*@2800, then it slows down and
tops out at 3400 or so with 32*.
I tried 34 and 36 and my butt-meter couldn't tell the difference, so I called 32 done.This curve lets me burn 87E10 full time, yet car went 93 in the Eighth @3467 raceweight.
To cover the torque loss using the lazy timing curve below 2800, I modded my Vcan for 22*, and adjusted it to come in fast. So, at 2800, at Part Throttle, She could have up to 28+22=50* for cruising, which with 3.55s and 27s, is 63.5mph.
My cylinder pressure, with the Eddies, is about 177 IIRC.
