It changes the dynamics of the airflow.The car does indeed spool quicker and it feels smoother. The extra torque down low is noticable. When we did a comparison on the Dynojet software I think there were some areas where there were 35 ft/lb increase of torque down low but we lost a little in the midrange and picked some up near redline. Overall, there was a little give and take and we are expecting the real give is when we can rev the car out to 7500 rpms
And everyone really has to remember that the baseline that we compared it against was 20,000 miles and 1.5 years ago. Look at the dates on the bottom of the dyno chart. So we feel as though we have a winner but need to do a little more testing.
Looks promising. Post video. You guys should make an option to buy a front mount that has those two charge pipes already lined up so all the turbo dudes gotta do is connect their turbo/s 
An APS style vertical intercooler would probably work best to have the most direct piping to it. Just a thought.

Definitely gotta compare the 'after' dyno against a stock plenum with the same heavier wheels, and higher mileage!
Most would assume, that it is Safe to say that there are Constant power gains throughout the rev-band (i.e. No losses) b/c of the additions of weight and time to the car!
Sweet!! just got to drive Tim's car and it feels great!!
To 'try' and compare it with my butt dyno against a built Greddy car, they feel very similar, but Tim's car is running 6-7 PSI where the G i have is running 13-14 PSI!!
It does feel like the turbos spool a bit quicker on Tim's car too, .. of course the c/r is a bit higher on his, ...But the 60-1's are Much larger than the Greddy 18G's, so 'normally' you'd expect the 18G's to spool quicker.
Also, this thing PULLS like there's no tomorrow up top!! DEFinitely need to raise the rev limit to take advantage of the flow! ANYone with a built motor and/or some cams with a higher rev can Seriously reap the benefits of this manifold!
