So I am piggy backing on an existing thread that has been napping for a while because I didn't feel I needed to start a new one on the same topic.
One of the things that drew me to buying a GTP was that I was getting 30+mpg on the highway with my Bonneville with an L36 which now has 290,000 miles on it, so in theory it should last a while. I haven't been able to get those numbers with the GTP, I got 29 with it on one trip. My mother only gets mid-30s with her tiny little Aveo and it is miserable to ride in for any period of time.
Anyways, I wanted to bring the topic back up of fuel mileage and ask or re-ask some questions either posed here or in other threads.
I understand the most important mod for better mileage is the idiot sitting in the driver's seat. I spent some time today reading ecomodder today and they have some good ideas on hypermiling... I would not want to be seen in a vehicle with a boat tail... ugly.
Here are some of their suggestions for driving for mileage:109 hypermiling / ecodriving tips ...
They also had some mechanical suggestions, some of which would help performance : 68 Vehicle mods...
I could see myself getting an electric water pump, anyone know of an electric power steering pump or brake booster for our GPs... in addition to using less mechanical power to run those, a person could shut down the engine and coast in neutral while still being able to steer and stop with help.
I was wondering if anyone has thought anymore about running two PCMs as was discussed in Running 3 Cylinders... one for performance and one for efficiency... or for that matter if anyone has heard anymore about a displacement on demand being retro fitted on any vehicles. The other thought connected with that would be to have all the cylinders not fire every other time as this should have the same effect as only running 3 as there should be the same amount of cylinders firing in a given time.
So in addition to those for mentioned ideas, good maintenance will help with mileage, a tune will as well as getting the engine to breathe better on both ends (intake and exhaust).
Anyone have any idea if there is a way to find out how lean a person can run an engine without burning it up. Honda had some engines they called lean burn that got great mileage.
One more idea in my ignorant blatherings... anyone ever heard of an HHO generator. A guy at the golf course I work at in the summer was in the process of putting one in his Honda Accord last summer, then this summer he ended up having a triple bypass and I never got to ask him about it. I am also moving at the end of the month because I got a new teaching job so I will not get a chance to talk to him. I guess the HHO generator is suppose to add hydrogen and oxygen to fuel to help it burn more efficiently, sounds like a gimmick to me but there are some websites that are DIY for these kits so it isn't just one brand trying to sell junk.
Edit: I found this info from an engineer that explained more on these HHO generators: http://fuelsaving.info/hydrogen.htm
Anyways, I had lots of thoughts and and nonsensical words stringed together, feel free to criticize at will.
