I bought desktop dyno and a little concerned about the test results. When I plug in all the info it seems to be off somewhat from experience. I ran a 350 chevy 8:1 comp, stock low performance heads 1.94-1.60, dual plane intake, 750 cfm, small tube headers without cats, a Crane 272H10 cam straight up.
I get 262 hp@ 4000 and 396 ft lb@2000. The hp seems to be fairly close but the torque seems to be off about 70 ft lbs or so. I know that it isn't going to be 100 percent but with the weather and alt. Dialed in I thought it would be a lot closer. Has anybody had any luck with this dyno.
