Locking the converter on the dyno

Whats everyones opinions on it? With a high stall would you lock it on the dyno? I'm pretty sure SAR did to make the 44x rwhp. Do you think it gives a better idea of what the setup is making since the converter isn't skewing the numbers?

i don't know what it would damage wise, but if I go back to the dyno, that's what I'm doing. I didn't even think of that when I went, first time ever at a dyno and was nervous as hell. my converter didn't lockup till 95 mph(5250 rpm), and you can see where it kicks in, and my peak numbers are off, LT4 conversion, a4, lt4 hot cam, 3.73s, 245 50 16s, tci 3500 stall, 275 rwhp, 338 tq. if you search my name, you can see my dyno sheet.

What's the point of locking the converter up on the dyno?? Are you planning on running it this way at the track? Bragging rights are pretty silly if they aren't accurate. You can easily verify the lack of efficiency of your converter on the dyno through Datamaster.
I hope you're aware you'll kill the lock-up clutch in short order by doing this. Single disk lockup converters weren't built to take the abuse of being locked up under WOT.

It's your converter...

Exactly.

Vigilante makes a multi-clutch disk if you plan on locking up the converter @ WOT. Normally at WOT, the converter doesn't lock up anyway.

Excessive use WILL burn up the lock-up clutches.

Re: Locking the converter on the dyno

thanks for clearing that up for me. I didn't know what damage it would do, but my power curves look wierd till the stall locks up on my dyno graphs, I don't think I had that high of peak power because of it. Did not know they weren't meant to lock up at wot. damn, I need a t56.

what do you all suggest I set it to in lt1edit? should I keep it at 95 mph?

Thanks,

Jeff
