Converter Slippage at top end
Currently using a 10 inch Yank 4400PT Locking converter.
Calculated a 12% slip based on Wallace Racing Calculator What is a typical converter slippage on Racing Converters. Trying to determine best gear ration for my 95 Impala SS for Stock Dan |

Re: Converter Slippage at top end
Going through this right now. I was at 13% and tested using John Deere Hydraulic oil and dropped 300 RPM. I think I'm at 9% now. It was just an experiment and now will remove converter to tighten up top end and hopefully keep starting line rpm the same. Debating on what to get converter set at because I race from 2000ft to 6500ft of air throughout the year and don't want to change converters.

Re: Converter Slippage at top end
The PT converter is a lockup so you should have ZERO slippage .
If you are using it as a non lock up of course your slippage will be higher than a real purpose built Stock Eliminator converter . |

Only question would be: Will you have enough steam to run a second under, or are you just looking to run the index? |

If it breaks PerformaBuilt will rebuild. Far less expensive than a built Th200-r4 and much stronger. Don’t have to make a new Cross member or Size a new drive shaft. More first gear for weight of car 8 inch Converter is being built. |
