I figured it would be worthwhile to give this thread a bump with just some collected driving data on the Roadrunner converter.
So the unit is indeed a lockup unit that will fit on a stock input shaft. Particularly nice if you want the extra stall speed in 1st and 2nd, but would like to retain lockup for economy in 3rd and 4th. Mine performs within the advertised stall speed (2200-2600) and will flash stall around 2500 RPM. I also did a brake stall test, loaded it up to 2500 RPM, and let it rip while keeping the selector in 1st. Engine speed jumped to about 3000 RPM, and stayed there during wheelspin until it caught, then it continued to rev on up before I moved the selector into Drive.
I could never light up the tires before, but now it'll do a mean peg-leg burnout.
For typical, in-town driving, its been fine. It does most of its shifting around 1800-2000 RPM in 1st and 2nd, which is great starting from a stand. Only when I first got it from the shop was I finding it a little "un-fun" to get started since it would wind up a fair bit (2200-2300) before it really started going. Now that its been driven on a few hundred miles, it starts off fine with light or heavy throttle.
Hopefully it keeps working well. So far, I have no standing complaints with this one, even despite the limited information on their website.
