Mine is a PTC 9.5" 2800@0psi L/U and spool up is immediate on the street with a billet 6765
This must be a new item. All ptc 9.5" converters were not lock up converters tmk.

. This is also true comparing journal to bb cartridge on the same turbo when launching off a t-brake. A bb is pretty much a waste of $ if the car is properly launched off a t brake.

Bison,
I bought my PTC on 9/23/09, the reciept is calling it a PTC 95200 Protorque 9.5" lockup converter, set to 3200 stall. I really can't feel any more then maybe .5 second lag when I go WOT with this old school 62 on the car now.

Protorque 3200 lock up if I am not mistaken? Just throwing it out there.
I am familiar with the Pro Torque 9.5" LU. Not bad units especially when use with 65 trim or smaller turbos. They need to be locked in high gear to get the best e.t.Bison,

I wish my 6157 spooled like that vid ,mine takes about 4 times that long.
Does your box look like this This is what is known as a "PTC"?
On a relatively low CR 7.5:1 234ci engine with ok heads and 212/212 my 18 blade 9.5" spools and old dinosaur 7276 bb with .85 ex housing in about .5 to 15psi on the t brake. Stall @ 0 boost/vac is 3300. Car has an xfi and timing/af are tuned in for max spool.
That's a great example of how much the tune plays a roll in spool-up. On a stock ecm car that hasn't been tuned for spool-up, that combo would be a lazy fat pig:biggrin:
I guess you have a few routes you could take, a restalled converter, a new converter, and/or cam and heads to up the air flow on the exhaust wheel... it's all in the combination of parts.
I almost forgot, 1st make sure you don't have a issue with your puck sealing the waste-gate hole in the exhaust side of the turbo, if it won't seal the boost won't build very fast because the exhaust flow/pressure is being diverted around the turbo exhaust wheel, and lost out the exhaust pipe. The other thing to look for is leaks/cracks in the headers/cross over pipe.
Good luck with your adventure if you decide to chase it down.

It is common for the PTC converters to be confused with Pro-Torque out of New York.
I have restalled several of the Pro-torque converters and they are nice pieces. They call theirs a 9.5", I call mine 10" but they will behave very similiar. There is only so much you can do with the lock-up based converters. They will always spool well if the combo is well matched to the converter and they will always begin to slip pretty bad once you reach the low 11 to high 10 second range. That's just the nature of them and being single disc it isn't recommended to lock them at WOT.
Now, they can also be built as a non lock 9.5 but the way they spool and couple will not change.
This is why I call mine the 10", to lessen the confusion when people talk lock-up and non lock. My 9.5 PTC non lock is not based on the same parts as the 9.5 lock-up's others sell and it behaves totally different.
