Thanks again to Craig and the crew. I was really happy with how it went (other than the I405 traffic) and my car pulled strong. This car has 36K miles, completely stock power-wise except for a Cobb Stage 1 93 octane tune, and I run a blend of 91 and 100 octane pump fuel. This result and how well it runs has me even more thrilled with the car and its long-term keeper potential.

nice meeting you buddy !

Craig's summary reflects 8 997 turbos signed up for his event, three have posted data sheets so far. I sure wish others would do the same with a list of any mods. My, I think stock, 09 posted a best TQ of 424 and HP of 395. I'm curious how that compares to others. Part of my motivation was a statement made by a friend that my car could have a tune. My dealer pleads ignorance and the car certainly runs well. I thought having more comparisons might help answer the question, as well as being generally interesting. Of course that applies to other P cars, but my particular interest is with 997's, particularly 997.1's. In any case it was a great day, thanks to Craig and his team, and a wonderful chance to meet other owners.

Bump so hopefully some others share results!

Hey guys I would have liked to attend but was out of the country.

Sounds like this is a very low reading dyno...like GIAC and GMG where 997.1's can be under 400 and 997.2's are low 400's (maybe close to mid-400's on a Turbo S). Contrast this to the Cobb dyno where my 997.2 made 501/536 stock. All of you would read much higher there. Mustang dynos can have their calibrations manipulated however the tuner desires as you know.

If world does another event maybe someone can keep track car, mods and results. That would be a nice way to compare.

mine only made 499/585 on that dyno. i was told , and believe from how it feels vs stock it's a 600hp car . so i do believe it read a good bit low . no complaints here, , dyno's are just tuning tools.

Can you share your mod list?

I agree with bigrpwr, also no complaints. It was a lot of fun!!
Mine had a high of 580hp, don't remember the torque reading.
My interesting experience was... they ran 8 cars before mine, that I was there to observe, and when mine went on their dyno they had to stop and make a few adjustments to their dyno. I was told my car revved too quickly and it "freaked" out their dyno.
I would like Craig to explain what he meant!!! Why would changes to the dyno be required when the prior 4 cars before mine were four turbos all with various bolt ons. Yet only my car required adjustments to the dyno. Does it mean they had to put a higher amount of drag/restriction on the rollers?
They have a SUPERB setup. 15 - 20 minutes to drive in, tie down, run 3 times, unstrap and drive out!!!!
No matter what the HP and torque results are, its best to compare to other cars on the same dyno knowing their modifications. But shouldn't all cars be tested on the same dyno setup?

Bigrpwr followed mine and he had to run on the same dyno parameters mine ran on. I wonder if he ran before mine if he would have had a higher readout?

FWIW I can tell you that for calculating power-to-weight, POC (Porsche Owners Club) applies adjustment factors to the results of specific types of dynos, because they do read differently. The factors are .95 for a Dynojet and 1.1 for Mustang. In other words for a Mustang dyno, your computations use an HP figure 10% higher than the dyno reading, implying that type of dyno reads on average 10% under other types.

Now World's is a Mustang BUT it is AWD and has the enclosure with the fans...not your typical 2WD dyno and I would not expect it to read identically to any other dyno. Dynos are best used as comparative tools as noted above. I plan to be back down to World after some mods...
