You just need an old Stuska Dyno like my builder has. Throttle in the right hand and the water brake valve in the left. Those Superflo and DTS type 5 second "zinnng" pulls are a joke IMHO.


I don't want to get to far off topic,but my Superflow will pull low rpm's and can be manually controlled just like his "old Stuska". But it can also be set to pull at different servo controlled rates which allows repeatable accurate pulls that a manual test can't equal,which makes for better comparisons from pull to pull.Not every operator wants to take the effort to make the changes.
I don't want to argue on here,but if you want some information on how different dyno's work,feel free to P.M. me.
