I asked you pointedly, did you ever build up an engine that was tune to maximize fuel economy.
You did not answer that. If you didnt ever build an engine that was tuned to maximize fuel economy then you are only speculating, which means you didnt "debunk" anything. I have heard about your actual experience, sounds like you have a masters at throwing wrenches and temper tantrums.
Why dont you stop by and I'll show you how accurate I am with those wrenches. Dont start slinging personal dirt buddy. Thats bullshit.
I have done all the modifications on a 4 litre that are both performance and efficiency related except turbo and SC. But I do know people with both.
Only an idiot would spend the money and time building a 4 litre specifically for the purpose of maximized fuel economy.
As explained previously, it doesnt pay.
I run the most efficient jeep straight 6 on this board. Bar none. Aluminum head, rollerized, long rod stroker, header work, intake, piggy back programmed, high compression, premium fuel, hot spark pluges, low range cam, large throttle body, custom intake system.
Its definately an efficient motor, and there is little else you would do to maximize efficiency on a straight 6. But only an absolute idiot would build a motor like that for a couple miles to the gallon.
Just like someone that continually argues the merits of fuel effiency in jeeps after bolting a 100lb tire carrier on their rig and blowing past people on the hiway at a buck 25.
So seriously, pick your fights somewhere else. Your hypocritical bullshit is getting really old.
