Running an intercooler, if it is set at 8psi, will see 1-4 PSI in 1 and 2nd gear, and then ramp to 6-8 in 3rd and 4th gear. So the power is really going to come in around the 800 -1000 foot mark and pull really hard on the big end of the track. The turbo makes power based on load. Loading is low in 1st and second gear, plus the intercooler on a low boost system is actually detrimental to making boost. The turbo is trying to make power, but having to pressurize the intercooler space, while the cooling effect is actually lowering the boost pressure as the air density increases causing the air volume to contract.

The positive displacement supercharger is making significant boost right off the line and holding it through the run, so it is going to have the power advantage during the initial acceleration phase.
