why are you running with the converter unlocked?

 

[Sweet6]

I have never locked my converter at WOT. From what I have read it is debatable on what is picked up. I just had my trans done and don't want to take any chances on having it fail faster than normal. Maybe someday, but I did not have the wiring set up to do it and it is not programmed in my chip.

what were your highest dyno #ers?

And that was last week. I drove the car home from the dyno last week and to the track yesterday. Did not touch the car in between.

your times at the track look about right for your dyno numbers. Personally I think you should try locking the converter. It's going to cut down on your drivetrain loss top end, but it'll cause more heat in the tranny. I have mine setup to lock around 100mph and I ran a 12.2@115 on 21 psi with a 2.0 60'.

 

[Sweet6]

If I do lock it, I would do it around 90-100mph. I have heard most guys say that they pick up a MPH or 2 by locking it there, but no ET gain. Maybe when I run the car again I will try it. Not sure if I am going back out this year or not.

if your picking up the MPH up top you should see a gain in ET. Since technically you should be reaching about the 100 mph mark at the same time if you're going to lock the converter or not since it's unlocked all the way until that point. But from there to the 1320 you're actually accelerating faster with it locked than you would with it unlocked picking up the extra couple mph and a little bit on your ET. I doubt it will really be a whole lot but I would guess between .05-.10 seconds, nothing too noticeable.
