Dyno #s

Kenneth called me today and said NPR is open for TNT on the 7th, gotta see if a Wed night works for everyone.

You coming to "Wes's Fun Dyno Day" tomorrow? I'm pitting a bone stock S197 stick vs auto with identical tuning to see if the 5R auto tranny holds its own. We'll probably have a bracket racing competition on the dyno also, whatever everyone wants to do for kicks.

Better be getting rid of that FMU and 24s and going with some 60s and a second pump.

I've got some more (safer) power in it for ya with more precise fuel control.

Stanger, how much did you gain by tuning?

This particular car was already dynotuned by another shop but I offered to try to work a little magic on it.

I baselined it when it came in on the old tune and then retuned it.

We ended up making it both safer (AFR was in upper 13s in higher RPMs on old tune) and made more power. I worked hard to get the average #s up across the band - this is what I look for the most. Peak numbers are neat and all but I will take the car with better average power/torque every time.

These are in stingy MustangDyne #s which is why the graph above (In DynoJet scaling) differs:

Max OLD: 261hp 268tq
Max Wes: 270hp 274tq

Average OLD: 193hp 243tq
Average Wes: 212hp 248tq

The averages speak for themselves. On an untuned car you can imagine even larger gains (although these are extremely good). This one made for an enjoyable evening of tuning, we had quite a crew at the shop to witness when word leaked out about the re-dyno-tune so I was tuning under the gun and taking time between each pull to explain what was going on and then predict what the next pull would do and why.
