^^ figured I may wait a few weeks to wear the engine in a bit beforehand but I'm planning to dyno mine down at ptuning before doing any SRI/exhaust/etc, curious to know if anyone has already run theirs on a dyno...

 

Couple places have. Descendant did theirs before adding their turbo and got something like 200 whp stock. Obviously, many people (including me) had doubts. Someone else ran a dyno with about 160 whp.

 

Ptuning uses a "heartbreak" dyno so be happy with 150 whp on it lol

 

Search feature works wonders...

I had mine on a Dyno Dynamics the first weekend with it. It made 145whp.

You'll find the figures are all over, so if your going to dyno make sure you use the same one for before and after.
The base number is only accurate to those that believe them but the gains will always show similar no matter the system.

I was so close!

 

^ LOL, but I can't find the Descendant one though.

 

This is my first tC I am going to dyno it this sat I live in LA so off course highest octane i am going to use 91 car has about 1200 miles on it
I used to be a Honda guy I had a Integra with H22A with I/H/E and AEM EMS I put 186whp on a Dynojet going to the see the difference

The premium fuel wont do anything for you, so save yourself the trouble.

But interested in seeing your numbers!

 

Found the Descendant Dyno for you guys,

Any time there's an increase in gas prices you'll often see news stories posing the question: "Is premium fuel worth the premium price?" After the "expert" gives his two cents, the reporter will often conclude thus: "There you have it-if your vehicle runs fine on regular, stop throwing your money away on premium!" The average consumer can easily be lulled to the conclusion that there are no benefits whatsoever from running gasoline that costs a premium price of 20 cents more per gallon. The logic experts use to justify their claims is straightforward: If you run 87 octane and your car doesn't knock or ping, you'll see no difference if you use 89 or 91 octane. There are also claims that if your vehicle is only designed to run on 87 octane, you could possibly encounter problems from using higher octane.
To test the "premium gasoline is a waste of money" theory, we borrowed an unmodified Jetta 2.5L designed to run on 87 octane. In order to get a more accurate read on performance and pick up on any drivability differences, we decided to do more than just dyno tests. We performed the various tests using four tanks of gasoline. Under real-world driving conditions, the tank was run from full to empty first on 87, then on 91, and then back to 87. With the last remnants of 87 the car was dynoed until completely empty, then refilled with 91 and dynoed again.

Vehicle Data
Engine: 2.5-liter I5, dohc, 20-valve
Transmission: Six-speed automatic
Mileage: 4,520
Current modifications: None Dyno Type:
Six-speed automatic
Baseline : 87 octane
Performance
Temperature: 66° F
Humidity:15% Peak Power: 133 hp @ 5976 rpm
Peak Torque: 134 lb-ft @ 3444 rpm

Test Notes
All testing was performed on the same day. All horsepower and torque numbers are quoted at the wheels. Keep in mind that the properly calibrated "Mustang" dyno produces more accurate real world numbers. While these numbers might seem low when compared to figures gathered from a Dynojet, what is important is the differences between each dyno run. When we strapped the Jetta to the dyno the needle of the fuel gauge was right at the red marks and we dynode until the fuel light appeared. All five of the Jetta's 87 octane runs were virtually identical with no major variations and at no time did the vehicle experience any knocking or pinging.

Test 1
Performance
Peak power: 138 hp @ 5908 rpm
Peak torque: 146 lb-ft @ 4060 rpm
Peak power gain: 7 hp @ 5790 rpm
Peak torque gain: 13 lb-ft @ 4150 rpm
Temperature: 67° F
Humidity: 13%
Pros
• Increase of 1-2 mpg
• Increased throttle response and smoother power transitions
• Reduce risk of knocking or pinging
• Reduce risk of horsepower loss from heat soak

Cons
• $0.20 per gallon price premium

Test Notes
We took the Jetta to a gas station about a mile away from the dyno facility and filled it up with 13.74 gallons of 91 octane gasoline. We then drove the vehicle for 25 miles to give the vehicle a chance to adapt to the octane increase and make sure there was no 87 octane left in the lines.
