stock is 255 and according to everyone who has done similar builds 525-575 is what is made after all the parts are updated from the ones that were originally drafted in the early 70s....modern tech tends to be MUCH better

"75% more efficient"- is that like making 525HP vs 300HP on the same amount of fuel?

[Striker2237]

YES SAME AMOUNT, stock injectors flow OVER 24 LB/Hour and waste huge amounts of fuel because the engine fails to use most of it. 24 LB/hour sized injectors in a V8 are supposed to make over 500HP if the rest of the engine is set up correctly (best it can be eff wise) even more so if it is supercharged as forced induction overcomes any small imperfections in the engine setup via simply forcing air past areas that would otherwise not flow optimally

Well you can get more efficient while using less fuel, compare 2014 Civic to a 2010 Civic. According to EPA, the 2014 gets 2-4 more MPG while having more horsepower (I think it's like a 5HP difference, but still).

You can also compare 1990 Ford F150 V8 to a 2014 Ford F150 V8 and you have a bigger engine on the 2015 and get better fuel economy according to EPA.

This should show how much room for improvement there is on cars without converting to a hybrid or all electric vehicle.

With my totally stock engine if I went foot DOWN I could WATCH THE GAS GO DOWN, this shows the massive amount of fuel the injectors are able to throw into the engine even though it wasn't using most of it (tested it for over richness at it was at an almost sad 6:1 AFR). With the work I've done so far I'm getting 3 mpg MORE and if I choose to hammer the gas it uses said gas more effectively and goes faster than stock....if I use the gas normally I can get up to the speed I like with LESS rpms needed to get there in the same amount of time as before and I can also keep the rpms lower at any given speed. This leads to me using (however slight it may be) less gas than stock

[Striker2237]

and as awcook said, newer engines make more power AND use less gas. Im taking something MADE IN THE 70s!!!!!!! and updating it to modern levels

[Frank Lee]

That's a nice increase!

From what I've seen on ecomodder, the '90s were the best years for Fuel Economy in smaller cars. But, those numbers are a little skewed since those cars have less safety features and produce more emissions (more emissions = more power for less fuel) whereas today we have too many safety features and produce close to no emissions (for compact cars).

The best years for Power, however, are whatever is most modern. I mean, we have street legal cars that go 0-60 in ~2 seconds! We have normal, everyday trucks that can haul 30,000+ lbs. All while using less gas than previous generations.

You should put your truck in the Garage on here, Striker, and start a fuel log. The log has helped me see where I am making mistakes and how I can make a tank last a long time.

Okay ill do that, in regards to what you said about emissions that is one thing that I'm very worried about. I installed headers, a mid pipe and new cat back with two precats and a high flow main cat but even though I did that (most people don't bother with cats on a performance car but I care about that sort of thing) I am producing slightly more co2 than stock and I'm trying to find a way to fix it.....

thanks lol, it just kinda always bothered me that my engine was not using it's fuel as well as is possible lol
