Thread: anyone have a "desk top" dyno?

Tweet

IMO that's a real generous virtual dyno, the numbers are plenty high.... I've had similar sbf's with better heads and a roller cam, the "real" dyno numbers were around 430hp and 460 torque.... 503 & 464 would be great, but I think the simulator is a bit on the high side....

1 5/8" headers would be better, and tri-y's would be better yet. The tri-y's on the dyno always seemed to bring a bit more bottom end to the party.... Timing is probably about right for street and cheap gas. On track days and 100 octane, you could bump it a couple degrees.... With the 5 speed and 3.54's must be a long winded thing on the straightaways!!!!

I've run desktop dyno against actual dyno numbers dozens of times and they're usually 5-8% "optimistic".

He asked for dd numbers and that's what I gave him. I would expect real world, with a solid tuneup, of about 450-460HP and 415-430 ft lbs.

hey geezer would you be able to desktop dyno my combo on my 'first 496 build a running success' post please? its not a very extreme build but i wouldnt mind a rough idea where im at for power and there arent any reputable chassis dyno operators in my area. all the specs you need should be there, need any more just ask. cheers man

5-8% is a reasonable descrepancy ..................

Your 496 comes up with 480HP @ 5000 and 547 ft lbs at 3500.

So figure a real world 440-450 and 500 ft lbs, a real "stump puller".

It should be stout in a heavy car like your Impala (or my cad!).

hahaha awseome! cheers man
