After reading several posts here about different FI methods and their various advantages and compromises, it seems the most ideal situation would be if the ECU could dial up whatever airflow rate it wanted (independent of the current rpm) just like it does for the fuel rate. Instead of having a blower that directly generates this airflow in real-time, why couldn't someone store compressed air in a resevoir and then meter it out electronically into the intake manifold? You would even have the added benefit of getting colder air as it decompresses. An air compressor of some sort running off main belt would keep the resevoir charged. In general, the resevoir would only have to have enough volume/pressure to store the air needed to get the rpms up during acceleration. After that, the input compressor should be able to keep up with the flow demand.

I'm sure this has been considered before, but I'm just wondering why it won't work or is too impractical.

I agree with the title.

A scuba tank is 3000psi and holds 80cu ft of compressed air. At WOT the 13B devours almost 500cfm - cubic feet per minute. Using 4 tanks as a resavoir and running 5psi of boost at that volume would last a few seconds and consume your trunk and back seat.

Then, if you did not want to take the tanks out - 3000psi pump shall be installed on the engine to recharge the system.

This does not take into account the enourmous danger of a 3000psi tank breach - ie explosion of aluminum shrapnel. Ouch.

 

good answer

 

1stRX8,

Thanks for the quick reply. I didn't know the Renesis sucked so much.

Thanks,

The more it sucks, the better it is.

 

Apparently a little CPR is desirable from time to time.
