I'm going to get a baseline dyno done this Saturday. This dyno baseline will be in Pure Factory Stock Condition...No K&N, no Gears, no Removed MAS Screen, no adjustment to the TB alignment; just exactly as the car came from the factory but with 1500 more miles on it.

Today I ordered the "Non-Comp Densecharger" from Demolet Motorsports. After the Densecharger is installed next week my plans are to have another dyno check done to see just how much improvement was made.

By the way...my dyno readings will be FULLY POSTED; in 100 RPM Sampling Increments from 2000 to 6000 RPM. There will not be any holes in the dyno numbers that will leave anyone guessing as to what the curve looks like. If I can't post the actual curves, all you'll need to do is plug the numbers into an Microsoft XL Chart and build the curve from the numbers...simple.

Like I mentioned before...BULLITT #00680 should be loose enough for the attack on the dyno by Saturday...should have about 1500 miles on the clock by then. I've rolled her stoutly through the gears several times and the engine is feeling much more responsive that it did prior to the 400-500 miles mark.

BLUBYU,
I think Bullitt680 is refering to the K&N Filter. Demolet offers his CAI with an "off road" (competition) Filter or a regular GT "legal" filter....So I suppose his reference to the Non-Comp filter is the GT leagal one........

Here are the numbers from my dyno this morning. This is the best set of the 3 runs.
BULLITT #680 had 1525 miles and was completely stock as it came from the factory except for a fresh oil and filter (MotorCraft 5W-20) change the evening before.
Run Date and Time: 5/26/01 @ 12:31:26 PM.
Acceleration from 2600-6000 RPM, Int=100RPM.

Looks like the BULLITT does make the power that Ford was claiming for it. Let the mods begin!

Thanx for the numbers!! Hopefully we'll start seeing more dyno numbers coming out and we'll get a better picture of what the real deal is.

Most important are those torque increases over the GT!! Now wonder what a little manifold and chip tune will reveal?

Regarding the removal of the Mass air screen..I happened to read an old issue of MM&FF,where they were dyno tuning a 98 GT I believe. When they removed the screen,power fell by 3-4 HP. They put it back and engine picked up. They assumed it slows or diffueses the airflow a bit so the MAF can read it.

i think with Ford STILL not releasing any numbers i think the change is due more to keeping SVT happy and not take away Cobra sales. Imagine what the numbers will be after cleaning out the intake! Hmmmm.....

When are you going to dyno it with the dense charger. I like the idea of the dense charger but want to know what to expect in terms of performance gain. Let us know soon.

I will be getting my car dynoed soon with the Densecharger. Dont have a base dyno though... And I have a hypertech. Should be interesting.
