This sort of tails off to my "response" to one of Chris C's posts, didn't want to steal his thread.
Does anyone have a rule of thumb, general guideline, or heck exact formula for reduction in converter slip and performance in the 1/4 mile?
And assume you have not been able to verify your converter at a RPM where it is hydro locked..
Say I noticed a 5% reduction in slip @ 40mph. (this is just a hypothetical, actual numbers are different).
Can I use this to extrapolate? Or do I need a timeslip or chassis dyno to get the real deal here on actual converter slip, and then I can begin to guess if it all it will make a difference at the end of the 1/4?
Say (made up examples again) you have 15% slip at your 1/4 mile mph. And say you get a new converter that drops it to 10%. Is there a formula for gain? or is it not linear or whatever?
I don't feel like forking for chassis dyno data because of what happened last time at the chassis dyno with a higher stall converter on a non-load dyno, but I have compared 40 mph and if I feel like going 80mph on the freeway I can get data for that too, but I haven't done it yet.
