Flash Stall for PTC 3200 rpm 9.5"

[TTipe]

Does someone know what the flash stall of a PTC 9.5 n/l 3200 rpm stall is?
Thanks

The stall rating is just a number, the true stall will depend on the amount of HP/torque the motor is making.

That's why one stall works in one combo and not so well in another as the variables will net different results even though two different cars may have the same converter.

What is the blade number? PTC 9.5 converters are never given a stall rating.

Thank you sir. You gave the exact response that I expected. I'll look at your combo and take a guess based on your 3200 stall. Thanks for the help.

I provided Dusty a "guess" (just another screw up) of 3200.

You have a stroker & ported irons. I've got ported gn1's. I think I'm going to fall short.

Flash stall under full power is the important number for optimal track performance. Do you have the orginal box? It is in the part number. It is also stamped on the converter and is visible in the car.

Isn't the flash stall the rpm the converter drops to on a WOT 2-3 shift?

 

[forcefed3.8's]

Flash stall is under full power, the rpm after the shift.

Do you have any idea how much power you are making?

Don't go by my combo. You need to be in the ballpark on yours.

I will tell you that my stock stroke motor with a TE63 ran just fine with the 3,200 stall and maybe you just need to get your tune right as that will also dictate how well the car launches.

You have an advantage in that you have XFI for more accurate tuning. Do you have a .63 housing on the turbo??

I agree but I think what he's looking for is brake stall by what he's describing.

I could be wrong and will let the OP correct it.

Then he wants true stall, which is pointless. He is getting hung up on a number because of a min stall for a turbo. It will spool fine.

It could be on the receipt??

He needs a minimum stall to achieve maximum spool. I hear what you are saying but that is one of the points I've tried to make in the past.

If the converter is coupling outside of the power band it can drag/hold the motor back until it gets on the pipe.

It will spool fine once he reaches the RPM at which his turbo will spool which might be in the 3,500 rpm range depending on the size of his turbo, tune and other factors.

If true stall is pointless then why not just put a low stall converter in everything from stock to 8 second race cars.

its depends on the blade,and the amount of power you can hit it with.

I have a "63e" big shaft which I was converting to 360 deg thrust. This combo is in build process. My original "63e" and 3200 stall looked like an ok match. Then due to getting the work completed on the 63e (thrust bearing) I started looking at the 45A, trying to dodge the ball bearing stuff. I have not purchased a 45a yet. I have a Precision .63 on the 63e. I'm sure a garret 63 housing will fit on that P trim wheel. I don't know whether the nozzle in the garrett 63 will put the gas velocity in the proper spot so I don't get surge.

I was looking for the stall from a dead holeshot. No one likes a sluggish car at the stop light. I'm interested in flash stall. It would be very nice to see a low 10 sec time slip. That will take a fair amount of work.

What blade PTC do you have? A 17 blade will be perfect for this combo, and will spool up fine. You are not going to have much of a lag difference between the 2 turbos. I am not getting into a converter debate here.

I'm strongly against converter debates.

You don't need to purchase the 45A, the 63 you have now will be fine. A garret .63 will fit, that's what I have on my TE63 Ptrim.

I didn't have any surge issues at all.

Are you running a precision housing right now??
