Looking to get some converter numbers for those willing to post. Looking only for 1/4 mile numbers. Even though it may not be the perfect way to check slip only interested in time slip mph and logged rpm. This is a good way to see converter performance. My next one will be a NLU, but would like to see how performance stacks up. Basic combo info would be good to if not in your signature.

Converter – Husek 3021 9.5 LU
Zero Boost RPM – 2300
1-2 shift RPM – 5500-4750
2-3 shift RPM – 5200-4650
Trap RPM – 5800
Time Slip Trap Speed – 120.14
Trap Gear – 3rd
Rear Gear – 3.42
Rear Tire – 255/60-15 MT drag radial
Car Weight - Full Weight (Never Scaled)

Thanks gusszgs. Only question is are the shift rpms 4200, and 4350? If you are in my condition, a couple of martinis into vacation, the digit off is understandable. :)

Not sure what your talking about. My car shifts from 1st to 2nd at 5200 and 5350 2nd to 3rd. The shift RPM'S drop to around 4500 or so if that's what your referring to.

Sorry, yes. Looking for the RPM drop after the shift. So the minimum RPM after the shift.

Are you guys with 200r4 transmission manual shifting or letting the trans shift on its own?
