Short Belt @ 2500rpm 118/247tq
Stock @ 4000rpm 195/256
Short Belt @ 4000rpm 197/258

Short Belt @ 5000rpm 208/218
Stock @ 5800 163/148
Short Belt @ 5800 168/162

Remove Accessory Belt:

Remove @ 2500rpm 118/249tq
Stock @ 4000rpm 195/256

Remove @ 5000rpm 217/228
Stock @ 5800rpm 163/148
Remove @ 5800rpm 182/165

Timing advance from 10* to 15*
@ 2500rpm stock = 117/245
@ 2500rpm bumped = 118/249
@ 4000rpm stock = 190/250
@ 4000rpm bumped = 195/256
@ 5000rpm stock = 197/207
@ 5000rpm bumped = 203/213
@ 5800rpm stock = 156/141
@ 5800rpm bumped = 163/148

Ice Intake (this one suprised me) (with flowmasters)
@ 2500rpm stock = 118/249
@ 2500rpm bumped = 128/269
@ 4000rpm stock = 202/265
@ 4000rpm bumped = 211/277
@ 5000rpm stock = 217/228
@ 5000rpm bumped = 223/234
@ 5800rpm stock = 182/165
@ 5800rpm bumped = 185/167

All stock car with flowmasters, modified it added quite a bit more.

Synthetic Lubricants added 2hp and 4-5tq.
Removed Air Silencer added 2hp/4tq @ 2500rpm and @ 4800rpm 6hp/8tq
Underdrive Pulleys added 2hp/4tq @ 2500rpm and @ 4800rpm 8hp/9tq

Then there are MAFs, Intakes, Exhaust, TBs, Blowers, Cams etc. They all have full dyno numbers from 2500-5800/6000rpm but I just shortend them to make it easier.

yep if it can cut a few tenths off of your et, then you know its going to be worth a fair amount of extra ponies.

When I was racing my car I had an ice can that the fuel lines ran through, and I used to ice down my intake before every run. It made a big difference on hot days.
