PTC Non lockup 9.5?

[wheelin]

This convertor comes with 16 fin or a 17 fin could someone explain the difference besides 1.?

thx mike

It comes with a lot more stators than that. I think 14-21. Its referring to the stator design. There are a lot of other variables that determine the converter spec that should only be kept between the person spec'ing the converter and the converter builder. The pump and clearances have effects as well the stator design. If you are interested in a PTC 9.5" PM Dusty Bradford. He will take care of your needs.

Got one last week:biggrin:

It's a lot to type and explain.

In that converters stock form, before it gets transformed by PTC, Myself, or Pats, it has 15 blades in the stator. Typically adding fins in a stator lowers the stall speed, but being that is a hand built steel stator, things like fin shape, angles that the fins are placed, and fin clearances between the pump side and turbine side of the converter will all have an effect on how the converter will react to a certain combination.

PTC makes custom stators for every 9.5" they sell.

Our stators are custom made for each setup .

 

[bison]

Yeah. Thats what i said:biggrin:

 

[blackplague]

I realize that they make each stator per combo,

PTC makes custom stators for every 9.5" they sell.

But the original question is what is the difference between the 16 and 17 blade stators. I just wanted to add that the stock stator in the converter core their using is 15 blades.:biggrin:

The difference between 16 and 17 the 17 will spool A little better .

Maybe. But mine is ideal. The one in my sig is a 16 and spools the 66 S-trim easily. It goes form zero to 20 psi in about .5 seconds on the t-brake. If he has a P-trim id definitely want the 16. The 17 may work better if its an S-trim or GTQ especially if the cam is larger than mine or the compression ratio is 8.0:1 or less on a 231. I only had about 3% slip at 134mph.

 

[chris718]

mike what core is it?

 

[Dusty Bradford]

mike what core is it?

Is this really necessary? Just buy one and figure it out yourself.

Are we talking 3 or 4 bolt turbos? 20 psi takes about 4 seconds with my set up, so that must be 3 bolt i assume? measuring off idle with the transbrake applied.

3 bolt .85 Precision. Its spools really fast on the t-brake. I played with the fuel map and it shaved about .5 seconds off the first attempt i made. A .96 4 bolt would take a lot longer even with a 66 and it would require a loose 17 blade on my application.

Dusty Im asking a question.I sell ptc converters as well.I can call tomorrow and find out.Go play with someone else.

That's all you had to do if you wanted to know. Call Lane, if he wants you to know he'll tell you.

I guess you heard that, Bradford...

The only thing I heard was the sound of women rolling off a golf cart:biggrin:

I keep reliving that moment,can't get it out of my mind.

Dusty,you gonna be at the FAT Tuesday race?
Im pretty sure I am coming down

Misty and Cyndi both have scars from that night...but it sure was fun...
