Hi all,

How much do those desktop dyno things cost? Are there any free trial offers? Which program is the best? Will it work with windows 98? Sorry I'm not a computer wiz. Just a welder.. graemlins/clonk.gif :D

Thanks
Aaron

The original Desk Top Dyno from Mr Gasket is about 36-45 dollars but is quite optimistic about the power you will make. I don't know about the new version from Comp. Cams.

The "genuine" Desk Top Dyno is entertaining for about one evening.

You'll need to spend LOTS more to get a decent program.

I have the one from Mr Gasket, and you can get it cheaper than that I purchased it for $10 at englishtown swap meet. Its just fun to play with look on ebay get it cheap if youd like.

I use my copy of D2K and Drag to look for trends when looking for part/power combinations.

And like already mentioned, there are better sim. programs out there if you want to be more "hardcore" and spend more money..

Pat Kelley's great "Dynamic Compression Ratio Calculator" site that you get to by his sig. and the one titled "Boost Calculator" on the web along with a static compression ratio calculator like the one at the "ROSS Racing Pistons" web site are also good sim's to play around with b/c together they look at pump gas octane usage..

Remember intake valve closing point AND static compression ratio/dynamic compression ratio set pump gas usage...

I got Pat's DCR Program. I guess with the dyno programs you can enter variables such as cylinder head #'s, cam timing, octane vaules, compression, ect...?

I have Performance Trends' Engine Analyzer v3.0. It works pretty well but I would like better. One thing, it loves a wide LSA. Comparing the same lobes on a cam with 112 LSA and 108 LSA, EA says the 112 will make more peak torque, more average torque, and a wider torque band. The wider torque band and higher average torque is correct but the 108 cam should make more peak torque. With it, if you just keep widening the LSA the engine just keeps making more torque, both peak and average. I don't think this is correct. A wider LSA should flatten the torque curve compared to a narrower LSA. I don't use it much anymore. I think it's about $120. They have one for some $350+. It has more bells and whistles but I don't know that it is more accurate. You can DLoad a demo but you can't change anything. Google Performance Trends for their web site.
