Not sure on the 220whp run, probably a preliminary tune compared to one that's more dialed in. These runs are on 91 Utah pump gas.
Doing some math I get ~510ci to fill a 6 foot 3" pipe, and around 450ci for a 12 foot 2" pipe. So the time to fill each pipe should be about the same. The Intercooler isn't giant, around 2.75" thick. Supposedly the longer pipe going under the car helps cool the air charge and reduce the dependency on a large intercooler. Keeping the intercooler size reasonable should also help with the response.
I expect there to be a bit less responsiveness, due to the turbine not being able to take advantage of the expanding exhaust right out of the engine. With that said, most aftermarket turbo offerings use pretty long runners and noone is complaining about the lack of response in comparison to other turbocharged cars that mount the turbo closer.
I hope the car still has good response. This looks like a more viable option to me. CARB legal and capable of quite a bit of power. You can also take out the price of the exhaust since this kit isn't really dependent on exhaust sizing. Though it couldn't hurt to delete one of the cats... or put on a nice header design. I would like to put this setup to the test at Miller Motorsports Park.
