So your Cobra is making how much HP?! Says who -- the manufacturer of the individual parts? Did you also add 10 hp for those Splitfire plugs you added, and another 20 for cleaning the rear-view mirror?
Well there's a way to find out for sure... measure it on a dyno! I'm trying to spark some interest in having a "Cobra Dyno-Day" here in Austin where we find out how much we're really making. In addition, you can find out if you're running rich or lean, etc.
Colvin Automotive here in Austin charges $75 for hookup and including one run on their chassis dyno, and $25 for each additional run. This includes fuel and air monitoring at the exhaust to measure fuel-air ratio. With approx 10 people, we can get this for $65 + $15 for each additional (They haven't confirmed the minimum number for a group discount yet).
Without fuel and air monitoring, it's $54 + $15 for each additional. I really don't care for this, cause fuel-air monitoring is very valuable.
BTW, the only reason you would want additional runs is if you actually want to tune on they dyno to optimize your tune -- measure, change jets or tweak the computers, and run again.
BTW 2, the numbers from a chassis dyno are rwhp (rear-wheel horsepower), after all drivetrain losses.
Typical sessions are 20-30 minutes which includes hookup and runs.
Let me know if you're interested or not, and I'll try to set something up for a few weeks from now.
