as Frank said... this is nothing like I-VTEC. OEM across the board on gassers still have several hundred pounds of pumping losses per stroke. Diesels don't... no throttle plate, no valve restrictions no pumping losses... sort of. Just gotta push the burnt fuel out of the cylidner and suck it back in.
I-Vtec is still going to have that.. whether the losses are generated at the plate or at the valve makes no difference.
As to the OP.
Not happening. Its possible to make the engine run lean. It is not very... convenient. Power would flood in as the revs increase combustion events would start to go off early or with heavy det.... engine goes toast... back down the resistance.. AFR steady state would be around 20:1. Which returns some pretty decent fuel savings...
Savings are devoured when the engine gets ahead of you every time you have to find the sweet spot with that specific road condition, wind speed, relative traffic.... at that specific moment.
Project at hand is a J32a2 in a custom chassis out of CF/FG twin turbo charged, with J35A4 crank, massive ram air intakes, massive ram air vents to cool the pre-coolers, massive radiators to cool the engine... and everything else is lifted from an Accord 97 and made to fit. not too terribly concerned about FE since the CL gets 30+ and this weighs about half as much and is more aero friendly....
