Here are dyno charts.
before head, OBX header, alta bigger intake hose (just remembered)
2/27/05: 165.6 hp, 150.5 ft. lb. tq.
I believe temp. higher than 80 deg. F., arrived hot and nothing done to cool intercooler except blow air over intercooler.
graph 1 below
8/12/07, after head 207.5 hp, 166 ft-lb. tq. Temp. about 80 deg. F., maybe less
intercooler cooled with some ice before the last run.
different dynos, 91 octane gas

Peak HP was 232.9, although that was before we fixed the issue with the dip, Peak Torque was 190.1, on the same run, if it hadn't dipped, it looks like it would have gone up to 240-245.
We made 230.6 WHP on the final tune, and 186 ft/lbs, slightly less than our "Best" run, but in my mind,

I knew there was a catch...
sad:
Looks like we need to put together a dyno tune day out our way for Jan.
I thought you were going to make this toon available for everyone who bought your head, or is it just for people who can come to your dyno

I see rustyboy did 23 runs on the dyno, what on earth would this cost? And what about us without a head, would it benefit us to come down?
his car was run using very large injectors instead of putting in a new fuel system like some do. Now that everything is tuned , it won't take long to get the tune on. Running stock or JCW injectors is very easy to tune compared to Rusty's car. We are working on a package system where all you do is put the tune on. We are getting close to that already.
I have been working on "BASE" maps for other cars that will get you close so the tuning only lasts a short while on the dyno.
When tuning like that to create the base maps and then fine tune them you would rent the dyno by the hour or day. Less expensive then the 3 pulls for $X standard for a reading.

Yeah, so what, that and 5 bucks will get me an overpriced, overhyped, blandish coffee drink. It's not about quantity, it's a about quality.

The cost for the dyno was $200 for about 5 hours, extremely cheap dyno time. The goal was to develop a base map so nobody has to deal with the what we did. You baseline your car, upload the base map, dyno again, then make adjustments as necessary, dyno the final time, and you're on your way :-). Once the base map is completed, only little tweaks will be required on the dyno (Really only necessary if you're trying to squeeze every last pony out of your engine).
