Testing strategy bolt togheter converter
Posted: Sat Dec 12, 2015 2:50 pm
Try to understand in which order to fine tune the converter I have.
Data:
Chevelle 2900lbs, 1.68 PG 8" spragless converter stall 6400 shift 7700, fall back to 6950 during shift 4.86/33.5, ET 1.20, 5.35/128, 8.51/156 8200rpm(on revlimiter). Will up date the shortblock so I can rev 8500 for the next season
598 cu engine, 1050hp@7400rpm
When i calculate the finish line slippage I end up in about ~13% slippage
What I would like to do is to reduce the finish line slippage and increase the fall back a little
The converter have 0,100 internal clearence between pump and turbine and I have a 29 blade turbine/ 41 deg stator in it now
I have a 45 deg stator on the shelf, should I put that in and reduce the clearence to 0,080 or what should I do? As I understand a 45 deg stator will reduce stall and fall back but maybe increase the slippage even more with the spragless stator.
Hope for some help
