Okay I got my dyno results back from Edelbrock today. The dyno results they got were based on using the stock carb. They tested two Preds..mine and another. The other they tested had a drop in K&N and Pure Polaris silencer with stock airbox and it made 38hp vs mine with the stock airbox and stock filter, HMF silencer, 167.5/50 jetting made still a little more than the other one however when they removed the airbox and used the K&N clamp on they found it made 3 more horsepower over the drop in K&N. However they found that the drop in K&N with airbox makes more torque but not more horsepower and the clamp on K&N makes more horsepower but not more torque. They told me that the jetting on my quad was spot on and it was another factor to why it made more horsepower than the other. They will be dynoing it on Tuesday or so with the Edelbrock carbs to find out what improvement that makes. I'll let you guys know some more then. Oh and just so you guys know I've never messed around with my needle clip or air screw. So maybe its the elevation here that makes it spot on without having to do those two things that a lot of people seem to be doing.
