here is your power graph

hehe messed up on the first one so here it is again

 

now your dyno table

 

Here it is.

 

An embarassment of riches, eh?

 

and a g raph to show you your volumetric eff
and manifold pressure

 

350 horsepower...

one of the car mags. did this exact same setup about a year ago, and they only got 275

 

Thanks alot guys. i think i need to go buy one of those. with your experience, how accurate are they compared to a real chasis dyno?

 

Well, it's only as accurate as the info you feed it. It also assumes that your tuning is perfect, perfect a/f ratio, timing, coolant temp, no detonation. But if you give it all the right info, and your tuning is right on I've run several comparisons to engines I know the actual dyno numbers on and it's error factor runs about 5% on the hp and 8% on torque. The tq numbers are usually a little high, and the hp numbers a little low, but it does go the other way a fair amount to.

 

is there where i can get a free demo of it or something i want to try it before i buy it. seems to be more valuable than gtech.

 

anyone running D.T.D. on windows XP????? Hate compatibility issues!!!

 

Yeah, I am. It works fine in xp. Try running in win98 compatability mode if you've got problems.
