That does make sense on the surface however the goal was great power and throttle response at large throttle openings, and very fuel efficient at small throttle openings. I must put a video together so you can hear how crisp this thing is ;-)
A small turbo produces a very small orifice for gas to pass through and therefore more back pressure. I chose a medium size turbo because it offers less pressure drop, easier smoother flow, and more cfm per lb of boost. I also plan to drop a new LS3 or maybe an LS7 in there later so wanted a system that will easily adapt over. Both LS3 and LS7 will get better mpg than my LS1 for the following reasons:
1 - LS1 is old - done over 100,000 miles
2 - A new LS3 or LS7 blueprinted and built right is very fuel efficient at part throttle - esp with some tricks to ensure very low leak down and friction reduction etc
3 - The LS3 or LS7 would go with a 6sp to get mpg up as the larger engines will see little (if any) mpg gain on an auto over what I have.
