Size of your pipes make a big diff. Any time you can an engine breath in and out better, improves power and gas mileage. BUT if you go to big with your pipes you lose power and mileage do to loss of back pressure. | | | Re: Want kind of gas mileage do you get. | Joined: May 2011 Posts: 10 stranger | OP stranger Joined: May 2011 Posts: 10 | I think the Moon Disc helped fuel mileage at speeds above 50mph and I didn't have wide tires either which helped. I used tall tires too, think front were 225/75/15 and the back tires were 255/70/15 if I remember right. The exhaust was 2 1/4" with glass pack bullet mufflers, sounded good. It wasn't real heavy, just two captain seats up front and the back was typical cargo van with carpet and paneling on side walls. I hope I come across a decent van with a blown motor because I'm thinking I could stick a Dodge 4 cylinder with an over drive trans in it and get some really good gas mileage. Has anyone seen a van that has been modified in the front and rear of the body to clean up aerodynamics for better gas mileage? There could be a big market out there for someone who designs a front clip that looks futuristic and adds to the over all looks of a van and of course improves gas mileage. I'm just saying. | | | Re: Want kind of gas mileage do you get. | Joined: Aug 2002 Posts: 18,536 Likes: 135 Supreme Master | Supreme Master Joined: Aug 2002 Posts: 18,536 Likes: 135 | Would a Dodge 4 cylinder really move a full size van?

I highly doubt this engine would have enough HP to move a full-size van. Even turbo-charged I just don't think there'd be enough low end torque.
V6 or Slant six at a minimum.

These are a turbo 4 cylinder. Bread trucks are pretty big,so I guess it would work in a van.Here is one on Ebay Arianrhod:2003 Chevy Astro Black Magic: 1985 Dodge B-250 Serenity:1985 Chevy G-20 The Outcast:1983 Ford club wagon Luna 1974 VW bay window transporter Freedom:1990 Ford E-150(parts van) Outcast Vanners van club Support your local 2% | | | Re: Want kind of gas mileage do you get. | Joined: May 2011 Posts: 10 stranger | OP stranger Joined: May 2011 Posts: 10 | I'm gonna put a 4bt/3.9l cummins diesel in my Dodge. just lookig for the right bread truck to pull it from. These are a turbo 4 cylinder. There you go, I bet you'll get 30mpg. Just think, if you do some research I bet you could even run that engine on used deep fry oil/bio diesel and have the best smelling van in the neighborhood. I was thinking of using a 4 banger out of one those little D-something mini pickup's that were around in the early 80s. It was a rear drive truck so I'm hoping it would bolt up to an over drive automatic transmission from a newer car. I would sacrifice high performance for good gas mileage, don't need a Van that runs 0 to 60 in 6 seconds, if it gets there in 10 to 12 seconds, that will be fine with me. I live in FL so I don't need mountain climbing power, a Van going down the road 55-65mph only needs around 60 horsepower max. 75 if the A/C is on. | | | Re: Want kind of gas mileage do you get. | Joined: Aug 2005 Posts: 21,211 Likes: 25 Supreme Master | Supreme Master Joined: Aug 2005 Posts: 21,211 Likes: 25 | The 5-cyl Mercedes-Benz diesel in the old Sprinters moved those big boxes around pretty good. I wonder how one of those would work.???
