How come the numbers were down from when you had the runs with the HKS? Was the weather warmer?

kreazik-s2k-

Hey... was the car using the stock ECM? You'll see less variance between the dyno runs if you had it running with a more aggressive ECM (like Mugen). It looks like your car was getting heat soaked and the stock ECM retarded the timing abit.

Hey krazik does the car have any other mods? Or just the headers.

But look at the torque curve!

Especially check out the higher res version. http://albums.photopoint.com/j/ViewPhoto?u...9833&p=34250113
Click here then on the graph.

The car is noticably peppyier(sp), is also much easier to get moving from a stop, and the headers weigh significatly less

krazik:

Something funny is going on. It was also 55-65 degrees on the day you dyno'd this header. This is actaully a bit cooler than when the exhaust system runs were performed.

So were the initial runs showing better results than subsequent? Did you do 3 runs each again? Since you had to swap headers, I'd guess that there was a 30min-1hr cooldown between the stock and Mugen runs. That should be enough time to stabilize the heat soak.

I guess I'm wondering what your analysis of all this is. Also, does it sound any different?

Looks like more low end torque, with no high end gain. It should be faster in the city but about the same on the track.
