I asked Yates about his crank hp claim he said he built an adapter for an engine dyno, possibly his engine dyno and had a company make a harness for a 3800 to run on it, I haven't seen proof but he says he actually engine dynod his 3800
ive looked at it with Opel, its fairly easy to adapt it, engine harness is fairly easy as well. in fact im working on a stand alone harness/fuel can so I can run my engines on the stand.
I wanna be able to dyno test the 80e's though
