I missed the tranny section when I looked down the home page.  After reading that, I am just as confused as ever  :)

A lot of broken parts does not make you a racer; it makes you a slow learner.

Here is a good post I came across. Slip isn’t always everything.
http://www.yellowbullet.com/forum/#/topics/2121025?page=4


Come on those guys are making some real power !!! nothing like our cars. Our 9/11 LU worked awesome. Yea we locked it to. Just sent it back a year ago to have it checked out . We have had it since 2006 from what I remember. Russ did go to a PTC non LU to try out. Worked great on the track.  9/11 to us is hard to beat on a street car goin to the track every now an then in my opinion (Mazda is a perfect example) The new PTC Melissa is working great in her car as she has gotten quicker (9.5s) still 3700# car . 6'0s in the eighth.

 It's like 99% of the women shopping in the Victoria Secrets Catalog and think it will make them look like the models. Put the book down and go back yo your trusty old  JC Penny Plus Size  book.  Whats good for the 6 and 7sec guys doesn't apply to us.
There is a more to locking up a converter then just jumping the A-F terminal and stepping on the gas.
When I did it years ago with a Vigilante converter I found locking it right after the 2-3 shift. Less strain and rpm pull down. If I remember right it netted me a ¼ sec. and 4-5 mph.  You also need to keep your rpms in your cams power band. If locking or less/more converter slip knocks you out of it your fighting a losing battle of tuning.

I was trying to get the point across that a locking up a converter typically only increases mph and you can’t alway judge a converter by slip percentage.

Again...conver tor choice is all important. Flash stall...correc t RPM at the shift points...slip percentage...e verything comes into play. I've seen a crapload of PL files with RPM drop from a shitass convertor of 2 to 300 RPM. Shitass lockup convertors seem to be all the rage these days.

I run Dave's 3021 LU and was seeing 7-800 drops between shifts before my pump slide took a dump.  Not saying it's the rage or anything, but seems to work ok for what I'm doing.......mi x of street and track. She's all fixed and ready for next years breakage  :icon_lol:
