How do I check my TC stall rate???

[Syclone#2960]

What is the best way to test my stall rate?

I'm suppose to have a 3200 stall rate but I don't think it is.

why do you think that? there was a thread on this posted in the last 3 weeks. can't remember who or what, sorry. but launching it makes a 3200 stall higher under load

I'm having trouble building boost against the brakes on a 67dbb turbo. I even have the exhaust dump open. I need to post a video of it.

i got a 2800 on a turbo like that, and can hit 12 psi if i wanted

Not me.. must be the front mount A2A...might have to back down to a PTE-63.

i don't think that is your problem, not sure how big your front mount is, you have an wbo2? if you lean it out bit on spool up it spools up way faster.

do you have 3 inch intercooler piping too? maybe its too much idk

I guess you can flash the stall convertor. Get the truck rolling about 10 mile an hour then stomp on it 3/4' peddle. The rpm's will go up to what the stall is.

Thanks Harmon I will try that.

I went with 2.75" piping instead of the 3" to prevent such a thing from happening. I tried leaning it out & it's still the same.
I installed a 2 step & have been playing with that last couple of days.
I want to rule out the TC stall first.

2 step should help it build boost.

What is the exhaust wheel size (trim) & also the A/R number on the turbine housing?

Can you actually hit full boost, or at least what your set to while from a roll and getting on it?

It spools up quick after it gets going...It's just the initial boost launch that is giving me hell. Takes a very long time to spool up to 8-10 psi against the brakes.

Not sure about the wheel size (3" inlet) & the A/R is .85.

The PTE intercooler is rated for 750hp at 3.5" thick.
