It was the 600whp fwd cars we were worried about steady stating. Also, we didn't want to have to drive the car on the dyno and move stuff around (like hvac), just becomes a pain in the ass.
Plus we needed the dyno for our 2700whp golf cart we are making, lol!
We are very happy with our purchase, so I guess he can be proud of himself.
I figured we could scream a honda to 10,000rpm with about 50lbs of boost and hold it there for about an hour. You can't do that? Damm.
The reasoning for the upgraded front retarders is simple. Our dyno is in the corner of our building. We can't access the "rear" rollers, unless we went thru the wall. There would be no way possible to steady state a 600+whp fwd (or rwd if we switched up the eddy placement, which would be dumb). We had the option and we took it. Sorry you don't agree with our business practices.
