Does anybody have any mielage numbers for a car with D-power stage 1 installed?
thanks

I think he meant the mileage. Well I have Cosworth Level 2, and the mileage is about the same, but it's hard to take it easy when you have that much power

What is 'Forbidden Doughnut'?


Welcome to [FJ].

I would think that the installation of just Cosworth's intake, CAI and ECU reflash (d-Power Level 1)would not improve mileage efficiency so much as be the foundation for d-Power Level 2.

'Forbidden Doughnut' is a reference to the Simpsons episode
where Homer sells his soul for a Donut.

I certainly did not expect the kit to improve fuel economy, but I was curious as to what degree it would be impaired.

ummm just extrapolating from the torque curve here, but it would not surprise me if Dpower stage 1 had significantly better fuel economy than stock.

my reasoning? Torque is a measurement of basically the force of each individual explosion. The torque is lower on the level 1 across the board compared to stock. This means the force of the explosion is smaller. THe main factors controlling the force (that we have to worry about) are fuel and air. Assuming the AFR isn't too different, that means that the level 1 kit will use less fuel each revolution, which means less fuel at a given speed, which means higher MPG.

Actually, I don't drive slow enough to share worthwhile mileage figures.
I hardly ever use 5th gear and I rev out 2nd and 3rd too much because, well... it makes me happy.


On Saturday morning I drove from LA to Monterey and I had to stop for fuel after covering just over 200 miles on a full tank.
That doesn't speak well for the fuel economy, but again its how you drive it that matters.
On the way home I got nearly 300 miles out of the tank, but that tank included the last leg of my trip up there, mileage in/around Monterey, and I was pushing it quite a bit on the way home too. That ~600 mile drive was the only long distance run I have really done in the car - most of my regular mileage doesn't involve much highway driving.

If I drove at a more moderate pace, I'm certain that 30mpg+ on the highway is entirely possible.

If it's producing more tq though you could run the engine at less load. So, I'm gonna guess the greater tq to load ratio the better the mileage.

I know what you mean
It's addicting sometimes. Speaking of miles per tank, the best that I got is 315 miles for a full tank, and that was a combination of normal and fun driving.

Drew AKA focus owner skid said that the more you uncork the cars the better gas millage you will get, It breathes better with d1 and d2 so I assume if you drove like before you had the packages that you would see an improvement.
