Just picked up this month's issue of DSPORT Magazine because I noticed that they are using the 2 as a project. Anyway, they dynoe'd the car and it made 99.61 to the wheels. This was with the 5-speed (don't know what type of dyno though). They also installed a K&N drop-in panel filter, it netted an additional 1.16 hp, putting it over 100hp to the wheels.

What does that mean? I don't have a clue. Is that a good thing or a bad thing?

They put the 2 on a dyno. It's a mechanism that measures horsepower to the wheels. It's a better figure, and what u want to know when u want to find out what kind of power a car is making, being that manufacturers measure their hp numbers directly from the crankshaft. Due to drivetrain loss there is a loss in power from the power output from crank to wheels. It's a rule of thumb, that on average there is normally a 15% loss of hp in comparing advertised hp, and what a car really has. I was surprised that with the 5-speed there was really no loss in advertised power, once it was dynoe'd. I knew standard transmissions were less restrictive in making hp, just didn't think it would be next to nothing in hp loss.

Well that sounds good. I like good news.

I am surprised how well the car does with the small horsepower & torque numbers. I drove up the mountain roads today & pretty much stayed in 5th gear the entire time right around 62 mph. I wouldn't have been able to accelerate in 5th, but in my old 4 cylinder truck I remember I always had to downshift to 4th & it still didn't have any juice to accelerate. The mazda2 does just fine, and it's a lot more fun to drive.

Its 2300 lb curbweight is what really helps it, so 100hp is plenty to get it going. While other underpowerd cars seem sluggish, the 2 does not. I can just imagine what 150+ hp feels like in the car.

150+ would make the car go nicely, but some decent suspension would be nice to add on too, generally an intake and exhuast should add about anywhere from 5-10whp.. which is not bad.

Yea I think I'm just gonna focus on suspension mods for the time being... Start saving for coil-overs, sway bars, strut bars, etc.

I heard Knight Sports supercharged version has 170hp. I wonder if that is just with the supercharger attachment or if they did any internal engine work?

yeah dude suspension is key to a light car with low power it gives it a huge advantage over the higher bulkier cars.

as for 170 hp i think there was prob minor internal work done, but maybe a wideband was used or just a full stand alone ecu
