Megan Header Dyno Results

[ChinoCharles]

Thank you Ashley, everything makes a bit more sense.

Mustang Dynos apply a small amount of resistance and use that load and not the mass of the roller to determine horsepower. Got it.

Russel, how do you like that HUD? It has to take some getting used to...

You got it. A mustang dyno is much better for tuning because you can simulate driving conditions with more realistic loads on the car, and do steady state tuning, That is more effective and accurate than using a Dynojet and doing WOT tuning.

What a fun experience man... I got to shoot the shit with the guys from Twisted Innovations and talk about this car and other cars. I learned a lot.

As far as the results, their printer was down so they are e-mailing me the sheets tomorrow. The gain was 3 or so horsepower, but that doesn't tell the whole story of what the header does. There was also a steady 3 ft/lb gain in the torque curve that came on quick and stuck around for a few thousand RPM. There was no net torque gain though. We did both runs in third gear.

It was funny... we first ran the car in fourth gear and got a whopping 125 HP to the wheels! I was so confused! As the boys said, though, "the dyno doesn't lie." It was even calibrated a couple of weeks ago, so for a second we were stumped. Then one of the guys in the shop said that some of these fuel efficient pump gas cars have two overdrives to save some MPG's. Anyone know if that is the case with the Yaris?

The third gear runs had us in the 105 HP range. I'm sure if we had done the tests in first gear we would have been in that 70-80 WHP range that is documented. Either way, we got the gains.

The guys at TI seemed excited about the prospect of having the car in their shop, and hopefully I will be working with them to develop some more parts for the car. You'll see threads popping up in the appropriate forums meant to gague interest in certain parts. If you see something posted that you would like to be on the market, post in the thread, because they're watching.

I'll post the actual sheets tomorrow.

Where's the pic of your header that's installed on your car?? Can you take some pics of it installed on your car??? i really want to see it, cause im thinking to get a header too .
