Nice Graph !
I have an observation and a comment, and a question.
some info. I have a 91 metro vert. I converted to 5 spd.( Homemade bed frame for transmission mount. As it wont take the standard mount.)4 dr metro tranny, higher gears than stack convert tranny.
I have recently installed a vacuum gauge, my engine pulls 18psi at idle. 21 is max decellerating. Gauge is cheap and my engine does have new rings. I use the reading for reference only.
So heres the question....
I notice than in 5 th gear that it sweeps faster (down) when I have to gas it, to get up hills and I can only maintain a 9 psi avg (2750RPMS). Compared to in 4 th gear when I'm running say 3250 RPMs, I can maintain a 10/11 reading. While driving between 45-50 mph in both cases.
So, Is it more effecient, to rev higher at higher vacuum reading, or should I shift to 5th and concentrate my efforts to keep the lowest rpm.?
Before I had the gauge, I always upshifted asap.
Now with the gauge, I believe I do better Reving.
anyone have a graph with mph/mpg on the 1.0 metro?
Thanks in advance, and hey anyone thought about a 20 hp Briggs powered metro/drivetrain. Or maybe motorcycle engine powered metro?
