I figured I would post my latest dyno outing from yesterday (7-14-12). This was up in Chesaning at the Cruise to the River Car show on X&M Hot Rods Mobile Chassis dyno. Same dyno as last year, and the year b4, and blah, blah. Basic set up is a 96-00 Explorer long block that I added my B-21 cam to and the rest of the supporting mods. Heads have not so much as been off this engine since Ford built it and I dropped it in back in '06 with 90k miles.

The graph shows last falls street trim pull in which it made 303/337, so instead of comparing it to my open header, short belt pull of 317/347 I used this one since I ran it in full street trim yesterday also. This pull was in the fashion I drive the car 85 miles daily, minus the drag wheels/tires I had on for the show. You can see how it didn't really show much of a gain in terms of peak, in fact it dropped tq, but it carried it out further, my guess is the long tubes were accountable for this.

Changes since last fall's dyno session were; went from BBK shorties w/h-pipe to BBK long tubes w/x-pipe, went from 40 series flos to Dynomax welded straight thru muffs, went from 3.73 gears to 4.30 polished/coated gears, stock radiator to aluminum, Pro M Maf to an 03-04 GT Maf, Stock flywheel to aluminum flywheel, new clutch, MicroBlue polished/coated bearings throughout rear end, and other misc other stuff that wouldn't make a diff. like the radiator. The car picked up from a best of 12.47@110 last year to a best of 12.29@111 this year even with a crappy 1.75 60ft so regardless of the "gains" on the dyno, it works. Although the dyno readings were both in SAE it should be noted that yesterdays air was horrid compared to last October's, and the fact of the 4.30 swap, would have been nice to see how it would have played out with the same gears but, oh well.

So, here it is...Enjoy.
