[quote]Without increased pump volume you are just wasting time.


Not quite, the extra boost increases the compression ratio.


More compression = heat. Need boost and fuel


Yes and to get more compression you need more fuel not just boost. You can achieve more fuel by adjusting the alda but only to a certain point. To move into the higher boost ranges and have effective results the pumps need to be modified to produce more fuel (beyond the mfg specs).

The efficiency of your engine is directly related to the compression ratio. A higher compression ratio will give you more power out for the same fuel in.
