I've been told I should have locked my converter when I went on the dyno a few weeks back. Would that have yielded me much higher numbers?? Is that still considered a legit way to dyno an auto with a stall?

 

I went from 280 rwhp to 330 rwhp just by locking the converter. That was on two separate dynos on separate days, though. But both SAE.

 

WOW. Is this normal? When you had those power numbers, was it legit to say you made 330rwhp instead of 280rwhp? Is the 280rwhp a little more accurate for street driving since obviously the converter isnt always locked.

 

330rwhp was the actual number. It was a full bolton, stock headed 355 with a 224/230. Locking the converter just puts the drivetrain 1:1 with the motor, it is the actual number.

 

Interesting... then maybe I am really making about 300rwhp or so??

 

How do you lock the convertor?
