2011 GT Steeda CAI will be available in about a week's time!
We have some numbers now we are ready to release. But first a little background.
In 5th gear this car dyno'd at 368hp but would hit the speed limiter before the rev limiter due to our car being a 3.31 gear equipped car. In 4th gear the car dyno'd at 336hp at the wheels.
We decided to work with the car in 4th gear. This will produce lower numbers all around, from the baseline number to the final number so they should not be used to compare against other cars.
Keep in mind a car with 3.73's will also dyno slightly differently in both 4th and 5th gears. Add on top of that the fact not every dyno reads the same, different days with different weather conditions produce different results, etc and it becomes nearly impossible to make accurate apples to apples comparisons.
That is why discussions on power numbers can become so heated. With questions whether one company or even an enthusiasts dyno number is accurate, what it really means, will it affect performance?... etc... etc...
In addition, with the speed limiter removed and rev limiter increased wheel speeds in 5th were going 170+. As unlikely as it was that a tire would blow out from that wheel speed we decided safety first and did our testing in 4th to keep the wheel speeds safer.
The attached dyno sheet is from pulls done on the same day, on the same dyno, on the same car, all in 4th gear on a manual transmission 2011 5.0 with 3.31 gears. This is the culmunation of over 8 months worth or work both here and with Ford right in Dearborn on pre-production cars. The numbers shown are the result of the cold air and custom tuning. Like our 05-2010 Cold air kits a custom tune/cold air package will be required for these gains.
Peak gains are 44.04 horsepower and 52.84 ft/lbs of torque, with even higher point to point gains. The highlighted point at 5500 shows a gain of 59.83 horsepower and 59.19 ft.lbs of torque. These gains are on 93 octane fuel. The baseline number was on a completely stock car with 87octane fuel as delivered from Ford.
