OK, my turn.
The "10" adjustment factor was "kilometers per second."
My best pull, on a Wester's 5.22 Race tune, with a Fujita intake and pipes, Mach Shorty and Hi Flo Cat, was:
HP = 250.2 = hp @ 5000 rpm
HP was a nice linear climb up to peak with a tiny little flat spot between 3200 and 3500
TQ= 282.7 ft lbs tq @ 3200 rpm
Torque fell away to 250 at 3500, and then back up to 260-270 at 4500.
Will post my charts when I get them from Goat via e-mail.
My impressions: The Wester's SS and Race tunes are very similar in power and torque, but the curves of the SS are a bit more refined. Don't know that I would go along with brother Goat's "much flatter," but they are somewhat smoothed out. Frankly, I like my torque curve better, but that's just me. The SS on a catless downpipe was good for a few more ft lbs (5), but HP was so similar as to be within the margin of error.
The comparison between the GMPP GM tune and the GMPP Wester's tune were interesting, revealing that the Wester's Race and SS tunes deliver more in every department and have way better low and mid range performance than the GM GMPP package. Sorry, boys, but this dyno don't lie. The Wester's GMPP tune is promising, but needs work. After yesterday, however, I am in no hurry to add the GMPP package.
U-238's bone stock pulls compared to Goat's and mine prove that, on a turbo LNF, with stock sensors, Wester's competition tunes:
(a) Vastly improve the stock power curves. U's had a deep dive in the low 3000s; generally, right where you want the power and torque to come on pulling off the line or accelerating out of a corner. The dyno guy shook his head in disbelief when he learned that was the stock GM tune. My peak torque (over 280) is right at 3200. That's right where I want it.
(b) Close to 40 more real honest to goodness rear wheel HP, measured on a very unforgiving dyno.
(c) Loads of torque. Over 280 at the peak. Although I like to see my curve a bit flatter.
Note: Critter's twin screw blower wins the flat torque curve prize. When those twin scrolls spool up, it pulls like a mule and the curve is flat as a pancake all the way to redline.
In closing, I am no math wiz. I know all dynos are different and apply adjustment factors, so reported hp and tq numbers are always a bit spongy when comparing results from other people's cars on other dynos.
But the big important takeaway from our dyno day was that it was very cool opportunity to compare the performance of multiple Kappas in various states of trim and tune on a true, no BS, apples to apples basis.
Personally, I am very satisfied where my Wester's Race tune equipped GXP posted. The numbers are good. Applying various conversion factors, approaching the 300 frontier. The power delivery as displayed on the dyno results are pretty smooth and consistent. This validates what my ass told me about the tune.
