| Well it was raining Saturday so what better day to be inside on the dyno? It was a pretty good turn out too, about 20 people in 15 cars. Apologies in advance as I forgot to write most of the results down. 
TT.net member icanznow in the white 2+2 next to the Nova. MarTTy4653(SeaTTle)'s charcoal TT 
Scott running damn near 400rwhp/400rwtq at 17.5 psi. I don’t know what he’s upgraded but I would surmise from the couple loud backfires that some tuning is needed. 
Marks modified Z31 Turbo, I don't know the details but I heard 16 and 20 psi being tossed around in the conversation. There was some trouble finding a reliable point for the rpm pick up but he pulled almost 300rwhp and 350rwtq. 
Marks other toy, a lightly modded Titan. Made 380-something torque and 260-something horsepower. 
Ken’s 350Z, stock to my knowledge but still made 231 rwhp and 183 rwtq. 
Mike’s TT, wired up with all the electronic goodies, Skyline ceramic turbos and a dual power seat conversion. Made about 360/360 at the rear wheels running a solid 1 bar (14.7 psi) if I remember correctly. 
Rob’s TT, just about dead stock sans the JWT intake. Made 261rwhp. 
Craig’s 530BB powered TT conversion, came in last year at 498 rwhp. It was running rich as hell today for some reason (like 9:1 rich) but still made 411 rwhp. 
Drag car that showed up, no blower, no nitrous, still cuts low 9s. 
Pretty sweet Nova with a 496 under the hood that revved to 6500 rpm and put down 350rwhp and 450rwtq. 
240SX conversion that came with Scott. I think it was only running 10 psi but it still made 170rwhp/180rwtq and considering the stock motor only makes 200hp/200tq that’s not bad. 
My Z did pretty good, 387rwhp and 360rwtq at 14.5 psi on 92 pump. 
Obviously still needs to be tuned but for just a boost controller and JWT ecu guiding it I'm not to upset with the out come. I would have thought that the peaks and dips at the start were the Profec being a Profec but the boost stayed pretty steady at about 14.5 psi except for the spike at 3850 and towards the end (green line on the chart and from watching the boost gauge). A/F is in blue, it doesn't have a scale unfortunately, but it was in the 11.3 to 11.8 range the whole way, a little lean at parts but not too bad. I was watching the timing on data scan and it waivered a bit at the beginning (which I would attribute those spikes too) but then held steady at 17 degrees under full boost. Given that the spikes in boost at the end of the run are almost on top of the spikes in the power I would imagine the curve would be pretty smooth with out them, it wasn’t showing any signs of knocking or boost leaks. If there are any tuners out there with some input I’d love to hear it. This was on a mustang dyno corrected to SAE standard using a correction factor of 1.06 for those wondering. As far as the Dynojet (inertial) vs Mustang (loading) debate: [ http://www.germanmotorcars.com/Dyno_load%20vs%20inertia_1.htm ] /\ That makes sense, maybe one of the more educate members can chime in on the matter. If I screwed up your numbers or name, drop me an email. [ http://www.hpranch.com/ ] It's a pretty cool place. The owner, John Garner, built himself a shop and decided he'd like a dyno in his garage. This is one of his other toys: 
Makes 1000rwhp with a supercharger, air-to-water intercooler and a rather large nitrous bottle. Good times, good people and even some good hot dogs. Look forward to doing it again once I get the AFC wired and purchase some wide bands.
