ok first ill give some info on both verts....both are 8"the coan was built for a W2 340 it has a negative fin angle(around 100-150 degree)5500stall behind my new combo stroker indy SB. the ptc was built for a stroker BB +250 fin angle unported stator 5400stall behind the same combo as above. the coan is 10yrs old been behind several combos the ptc is bacially new.i lost almost a full 10th in 60ft with the ptc bacially 1.5ths on the top with same mph and rpm trap(same slippage).i bought the ptc because i wanted to use NOS figured it should be tighter but dissapointed.
Was the PTC built by them for your new combo? Or was "the ptc was built for a stroker BB +250 fin angle" that someone elses combo?

Your PTC may very well be a peice of crap.
BUT, these converters are not anyway shape or form the same converter. By your own admission you ordered the converters for different combo's.

they where both built for different combos.....my complaint is the slippage of the ptc.it is equal to the coan which is 11%last time i did the math.

back when i had some money, i bought a PTC and a spragless from TCT at the same time. they ran exactally the same.
TC are one of those things where i wish i could buy 5 different converters and try them all. I now have one from Ultimate
