Whats the point of paying for that crap then messing with installing it when there are tons of programs out there that will show you the cars power/torque and simulate a real dyno (and many are very accurate I must say)?

The difference between theory and practice is that, in theory, there is no difference between theory and practice.

^unless the Theory is proven wrong. but then again, its no longer a theory anymore, haha.

Hmm.

$1,500 actually isn't all that bad, especially since it seems like it'd be relative easy to move between cars. Factor in the vehicle's service brakes, and assuming you have a long, empty stretch of road and a co-driver, you have a brake (load-bearing) dyno.

I wonder how much the liability insurance is.

Figure each (real) dyno tuning session would be at least $200.

They assume a perfectly flat road with 0 wind.
Do you have one?

I have one, but it's usually blocked by large herds of perfectly spherical cows.

Fairly flat with a little wind will skew the numbers by no more than about 5hp/tq. I know I know, where then do you "draw the line", but IMO it gets you real close. At least close enough to help you tune quite a bit. I've been tinkering with these programs on Subarus/Evos for years now, and they're insanely accurate. Assuming you don't fudge the numbers or dyno off a cliff with 100mph tailwinds or something.

Jason i'm assuming youre at SEMA?

JasonC SBB

No, I read a post about it.

LOL @ Joe's spherical cows.
