I think dyno numbers on these manifolds are all worthless numbers. You have to take these cars to the track to really see the benefits. I've had parts that showed no gains on the dyno but picked up at the track. The dyno will most always disappoint you unless you have an operator that manipulates the number for you. My C7 only picked up 15 rwhp on the dyno with long tubes and no cats, went to the track and picked up 4 tenths and 4 mph. Went from a Lt1/87mm IM to a MSD/95 mm lost torque on the dyno and ran slower at the track because my 60ft times and 660 times were slower. We had to raise the rpms shift points and continue to extend the shifts points to get it to run 10.90@128 from the 11.00s we were running with the LT1 IM, but it took more than a 1/2 dozen passes to get it there. So, once again dynos are for tuning, the track shows the true torque and hp if you can hook the car on the launch.
