Superflow Autodyne dyno?

Anyone ever hear of this dyno before...? A local speed shop has this dyno, which I have never heard of. Just curious.

Superflow AutoDyn SF-840 chassis dyno

I hear it reads similar to a Dyno Dynamics dyno and a bit lower than a Mustang Dyno. There's one down the street from me that I've been thinking of visiting.

Does not matter how they read. just do a map 0 run at the end and check the delta.

I ran my car on a superflow a long time ago. It put down 398hp and 410tq. They say it typically reads about 9% lower than a dynojet.

I ran my car on a Superflow Autodyne 30 back in Feb of 2011. Stock results were 290 rwhp and 309 ft lbs tq. After adding the JB+ at 75% results were 337rwhp and 361ft lbs tq. I am not absolutely positive as to the accuracy of these dynos, but hear great things about them. I mostly wanted to make sure that my psi was remaining at safe levels, which final psi was 10.5, and I still have 25% left on the JB+

Baseline about 25hp and tq too high.

Superflow is an old and trusted brand, but they primarily built engine Dynos. I think that they are newer on the scene of chassis dynos.
