Terminal speed is so aptly named... <img src="/forums/images/graemlins/scared.gif" alt="" />

A few things to note on the turbine powered compressors (turbos). You can get boost at whatever RPM you would like by matching the turbo coreclty. So its possible to get signifigant boost well under 3500 rpm with a turbo.

The tiny hairdryer on mine spools up at about 2400 to 2600 rpm, by 2800 rpm I have 12 to 14 psi of boost pressure.

That will hold to redline.

Frank is correct its the mass air flow that matters, not just the pressure. Decrease the restricion in the motor and you can flow more air at a given pressure. The other factor is temperature, cooler is of course more dense.

8 psi at 280?f is a lot less effective than 8 psi at 180?f.

Thats the fun of an intercooler....The faster you go the denser your charge since it will cool better. As far as response goes it will be very interesting to see the combo off a TPI with a blower, of idle should be great.

My system is at the opposite end of the spectrum, TBI and a turbo. It takes a tiny bit of time to respond from a standstill, almost a second, or about 1/2 way across an intersection, on a roll its instantanious.

Someday I will get a TPI setup for mine.

Looks good!
