How about using a real dyno?

Wheels do not make that much of a difference in real life.

 

wow... the figured kinda surprised me...

Here's one for you Shawn...

Even with the reduced redline... why not try a 04 ECU in your 02? it will redlines before peak but at least we can see if the ECU has something to do with it...

Also, in the future, cams from a 2.2 into a 2.0 would be interesting to see also.

 

Well, if there is a dyno with a 03 w/ vafc vs an 04. I figure it'll only be 10 some hp diff which is expected from the displacement increase?

noooo, i want an 04 now......

 

Umm... the Dynapack is a real dyno. If you're referring to something like a Dynojet or Mustang dyno, then that's different.

The 2 latter measures power at the wheels/tires but you can fool the dyno into thinking you have more power just by running higher tire pressures. (less rolling resistance) The Dynapack is free of this kind of error... for example.

FWIW, wheels do make a difference in real life. Obviously, acceleration and braking are affected by the changes in just weight alone.

 

Wheels do not make as big of a difference on a dynojet as people seem to think.

Switch from stock wheels to something an inch bigger in diameter and there will be very little if any difference. I have tried most of the dyno tricks out there.

Personally, I am a follower of the Dynojet and like to know the power at the wheels since thats what I am going to be driving.

 

i think we otta wait till we get more dyno runs on more cars. i think UR dynoed their stock s2k about 20 whp less than most and when they intalled the turbo came with to big of an increase which to date most UR turbo kit owners dont see on their turbo cars. I think we need to see about 5 more cars to draw a conclusion.

 

Wheel weight does make a big difference on a dynojet. Its a fact and it has been proven. Add 10 lbs per corner (going from a 15" to a 17" wheel for exampel) to a 100 hp Civic and you'll see the dynojet reading go down by 5-7 hp. And on the road that effect is magnified because you still have to accelerate 4 wheels, while on the dyno you're measuring only 2.

Whether you're measuring power at the hubs or the wheels, you're making a comparison. The absolute number means little. Even engine dyno's vary in output, so you always have to make a direct comparison. But the Dynapack offers a lot of advantages over the Dynojet, as race winners/national champions in NASCAR, Speed World Challenge, import drag racing, NASA Honda Challenge and other series have already found out.

BTW, the car is a production car (#18). However, it was given to us by Honda PR, so yes, we want to test a customer car just to be sure.

UL do you know if the current aem ems will plug and play with my04 also?
