When locking the torque converter on a dyno, do you lock it a low rpm before you start making the actual pull, or lock it up once your up in the upper rpm range??? Thanks

lock it down low. they say locking the converter is bad for it on the dyno, and it is, but if your not making a ton of power it's no biggie. lock it low, around 3k

hoping for 600rwhp, not to much lol...and 3k is usually where we start the pulls anyways

Lock it before you start the pull.

Ended up with 572 unlocked and 609 locked...not bad for just 9 lbs, to bad my car is so damn heavy though

That's not a bad drop from locked to unlocked for that kind of power. What stall do you have?

i can get 3200 on footbrake before it starts to push...and on transbrake ive never actually looked lol...I need to get hptuners so i can start logging my passes and see whats going on

TB is probably 4500 or a lil higher, ill try to pay attention next time
