I hate to say this, but I'm looking at your datalogs and your converter is acting like a 3200.
Here's what I mean: The 2 datalogs I have of camarojt's car, his 3600 Circle D converter shows peak tcc slip at like 4000rpm on launch. IMO, he's basically got a 4000 stall, and has cut 1.5x 60' times. My old car had the 3600 Yank in it and consistently had peak tcc slip around 3800rpm, so I pretty much had a 3800 stall and was cutting mid 1.6x's. All 3 datalogs we did of your car tonight show a peak tcc slip at 3200rpm, and you ran pretty consistent mid 1.7x's. Maybe someone that knows a little bit more about torque converters than I do can confirm for us that tcc slip on launch is a decent indication of actual stall rpm of a converter? Should be. |

Really, I'll call and ask Matt tomorrow but I told him 3600 and he confirmed that

What brand converter did you get? IDK a lot about them but I do know yank is a tighter converter than circle d

Doesn't Stall Torque ratio (STR) come into play in this situation? I think the Vigilante in my Formula has a 2.45 STR. Just a shot in the dark here but maybe that'll get someone's wheels turning.

I hate it when you have to wait in a staging lane FOREVER.
