trap speed and hp?
What would you expect a stalled auto LT1 trapping 100mph to dyno?
280?
270?
260?
I'm just curious as I dynod only 231 stock and trapped 95 and now I trap 100mph and I am surprised it trapped that high at all.

Try this calculator. http://www.wallaceracing.com/et-correction.php . There's a bunch more in the stickie on the Drag Racing page.

Stalled autos do not follow the normal hp/ET/trap/dyno/etc formulas as manuals. Dont worry about what it puts down (or even what it traps, to a point). The ET is what is really important, and like you noticed gears and a stall help a LOT, even though they wont help on a dyno or change your trap too much.
I agree that you're def not putting down almost 300 with a bolt on stalled auto LT1

I've never heard of using "trap speed " on a dyno, but rpm will affect your wheel speed. Revving to 5600 rpm on a pull will have a slower speed than if it was revved to 6000 rpm but the hp and tq could remain the same.

60'--- not recorded from regal destroying light
I2----5.494
I3----8.545@79.8
I4----11.136
ET---13.468@99.9
This was my fastest ET, but I trapped 100 hotlapping 5 minutes later (13.53@100.1)
Huh? I'm talking about when I dynod 231 whp I went to the track and trapped 95.
the General rule of thumb is 1 mph gained from every 10hp so based off of that I gained 50hp, but I don't buy that at all. I just want to know where the 5mph came from.

With the same mods I currently have in 80 degree weather I was still trapping 98.7 so at most I'd have gained 1 mph from that first stock run.
It's a performabuilt 3200 stall. Seems to be pretty tight.
