Ok lemme see if I can explain this..I have a heavy 3900lbs car with a 3.42 rear gear a 468 with 6x heads and a victor Dom set up.Car runs 11.9@115 spinning ,I go thru the traps @ 5100RPM.Ok heres the problem,I ordered this converter from PTC 3800 ten inch,It flashes in third gear rollin 10 mph to 3900rpms.I did not tell them about me using a tranny brake but I did tell them about the NOS useage.I have the NOS wired into the trannybrake with a relay.Heres my question,will the trannybrake make the converter not lock up as well on the gas?When I tried it out,the rpms came right up to 6000 and when I shifted they came right up to 6000 and I didnt gain any eighth mile MPH from my motor run.I just unloaded the car and tried to footbrake it and the tires spin @ 2800 in my driveway and it stalls at 3900 against the brake.Any suggestions before I pull it out and ship it back to PTC.
Thanks,
Roger
I did check the fluid and it is clean and not burnt.

It sounds to me like you're laying the fins over inside the converter. While this shouldn't be happening in a properly assembled nitrous converter, they should know that you're using a trans-brake also. A lot of companies will only install one anti-ballooning plate in a non-trans-brake nitrous converter. You need anti-ballooning plates on both the front and rear of the converter for your application. As for the fins laying over, if that is indeed the problem, that issue can come from poor quality components, poor workmanship, and/or a lack of furnace brazing on the fins.

What Ponchopete wrote or converter clearance problems. Converter, anyway you look at it.
