Any more results?

MK19, were fans placed on your rear bumper/intercoolers?

Post screenshot of your dyno sheet!

What a great day, thanks to Craig and his crew. Also great to meet so many fellow TT owners, some really impressive cars present, and a couple that pulled really hard. World Motorsports is an first rate operation with a large and well equipped shop. A look at the breadth of impressive iron in the shop speaks to the reputation the place has acquired. They work on a wide spectrum of cars but love working on and modifying P cars. Also, very impressive crew doing the actual dyno testing with military like precision, no worries about you car in this place. A really first rate dyno too BTW. Craig will be e-mailing participants their complete data from the runs this week. I hope he does a summary of the results. I think the cars would have to have hidden identities, some participants were pretty competitive about their numbers. Never the less I'd love to see a summary, maybe not by year but by car type. Personally I don't care if there is attribution of my car and the numbers, I'd just love to see a summary of how the various cars did.
Regardless, great job by Craig and crew. If he ever does this again, I'd highly reccommend it.

I agree -- Craig, Eric, and crew were great. I was there Sunday morning so it was quiet. My son enjoyed taking video of the dyno runs and feeling the crazy wind in the dyno room.

My car turned out results lower than I expected - but it is what it is. The only thing I wonder is if they didn't enable sport mode (I didn't remind them to), which does increase boost substantially on my car. I was guessing I'd hit ~475+ whp....

Here are my specs and results:

2007 Turbo
50,100 miles
GIAC tune (91 oct)
Wagner intercoolers
Kline SS exhaust with 200 cell cats
GT2 slave and Sachs "2.5" clutch/PP

422 whp and 458 wtq (AFR avg of 12.2)

On my other runs the power dropped quite a bit and the AFR went pretty rich, especially after 6000 rpm.

I wouldn't hesitate to go there again -- great team at World Motorsports! Maybe its time for a remap, boost leak test, tune up, or re-baselining my expectations

Here's my Dyno Sheets.
Looking for leaks/causes for high AFR.
Kevin, your help and advice is highly appreciated. We need to talk about a tune too.

Here are the next 3 Pulls, showing the erratic and high AFR.
Thx for any help seeking the cause of the apparent intake leak??

Kevin,
No fans at the intercoolers, but a huge 60HP turbine blowing air over the whole car through 3 x 4' diameter ducting (impressive). None of the gage temps went over about 190 according to the tech. Other cars made much more power with the same set up, but of course they were modified or likely modified too.

Did you guys get the data files? THe Mustang Dyno creates a TRB file for each run, and if the shop gives you the files you can plot your own graphs & see the WCF data, etc.. The PowerDyne software can be run in demo mode (and it's free) and it's pretty cool to see what's there.. Anyway, let me know if you want help in setting it up..

When I did my pulls last year I recall it took a good 5 minutes or more for the IATs to come down to something reasonable (~23C) with fans blowing into the intercoolers before they started the pulls.. The car idling in the bay, etc. really heat soaked the intercoolers. If they just strapped you down and started without any cool-down period then it could account for some of what you're seeing.

I understand that high IAT's disrupt power, but how does heat contribute to high AFR's?

Here are my dyno sheets as well. As far as I know my 09, a CPO car I bought from Rusnak a couple of years ago, is stock. I've have had a knowledgable person tell me my car could have a tune, but who knows? It certainly runs well, and pulls like crazy, but then this is my first turbo, so I don't have a lot of comparisons. Regardless, thanks to Craig and his crew it was a great day.

Yes........nice Numbers Bryan550. And except for the first run, low AFR's as I might expect.

Guys I think that there AFR testing was not accurate with some of the owners/cars that I have seen.

550Bryan, AFR for the first run does not make sense, the two later runs were better. I have seen this pattern on another customers car.

MK19 I sent you a PM.. Your AFR's are not correct.

^^^ I had the same issue on my Cayman S that I got dyno'd that day. One run had a really high AFR with the highest HP/TQ numbers, but the other two looked normalized with a slight decrease in power.

On Bryans run it's just a simple deal where the sensor came out from the exhaust on that run.

Thumbs up

I sure hope other participants post their numbers with a description of any mods, if any. The comparisons would be really interesting.

As for the numbers, and I expect this to create all kinds of reactions, so I'll stick to what I saw only. I witnessed 4 cars run in the following order /results;

1) '09 TT said to be full stock (but we can't be sure it didn't have a tune) - 400hp
2) my '11 TTS, dead stock, 401hp, 401 ft-lbs (a bit disappointing, but probably realistic 25% off of the 530 crank shaft HP advertised. 25k miles, on original plugs.
3) '11 TTS, Kevin's Tune and an EP (fuel unknown) - 480hp (nice number)
4) '17 Carrera S, Stock - 340hp (wow big number!, 17% off of the advertised crank hp).

It was interesting to see how hard the numbers fell on second runs due to slight increases in internal engine temps that capped the overboost. My car never got above 360hp after the first pull. And World has a huge 60hp wind tunnel like blower pulling air through 3 x 4' diameter stacks.....about as close to road conditions as you might hope for.

Thanks again Craig and crew!

craig did a great job for sure, and the facility was so nice !
