It was on low boost and pump gas, first pull it made 435whp because he stoped at 8000rpm. So the second pull I said dude go to 9000rpm hit the revlimiter. So my last pull it made 470whp at 8500rpm. I was like wtf I wanted him to go to 9k because from 8500-9000 the car picks up a solid 40whp oh well. The dyno was very accurate though comparing it to synapse dyno. I looked at my graph from synapse and my graph from this dyno and at synapse I made a little over 500whp on pump gas but that was at 9000rpm. At 8500 rpm it made 470ish which is spot on with what it made at this dyno day. Damn dude. Excellent setup pulling that hard all the way to 9k. All my dumps peak about 750-1000rpm before redline. --- _[View the full topic](https://forums.speedlife.net/t/dyno-day-open-house-this-saturday-april-30th/258133)._
