How about a small electric compressor directly in the intake that runs constantly to provide a small amount of boost maxing out at say 4 psi. Boost is regulated by a stepper motor controlling a very small wastegate or very large idle air control valve. The stepper is contolled by the ECU using input from the throttle position sensor. Not much compression of the air and it could come from a cold air intake so no intercooler. It's pretty simple electronics. Would it work and is it worth the trouble?

Simple arthimetic, Dave. So simple I screwed it up! 60 amp hours is roughly the usual rating on a car battery. Watts = amps * volts. 60A * 12v = 700W for one hour, or 42kW for one minute, or 2.5MW for one second (yow!). 42kW/8.8kW = 4.77 MINUTES (not seconds, my mistake). So, you could get, with one car battery, enough boost to last you for several runs. There's enough energy in one car battery to give 300hp for 11 seconds, assuming you could actually get that energy out without melting everything. |
