Agreed! By today's standards I'd be looking for 100hp per liter which in my case would translate into 750hp. But that is not what I am looking for. The name of this game is gains in mpg and torque.
Brian thank you for your post, and explaining what I needed to know. My concern with the intake is that while the air box draws air from the outside it sits a top of the radiator. Look at the link on my first post for pictures of the intake system.
Ed, K&N does make a filter for my van. It is a...
Gruntguru,
My van does use a MAP sensor that is easily accessed. You stared "If the car has a MAP sensor simply compare the reading at key-on-engine-off." But you didn't say what to compare to.
Could you please clarify.
Thank You
You guys have been great with your comments and suggestions, which I plan on following up. But we have not really touched my original question about exhaust pipe sizing.

Tmoose - thanks for that info that will save me from crawling under van and looking for the tag on the diff.
Gruntguru- thank you for your comments. I agree that some of these upgrades, such as the aluminum radiator, will not help gas mileage.
I will try to answer all your questions:
Current gas mileage - The van is new to me so I can speak from experience but what I have read is 8 mpg - 12 mpg. If I can get the intown mileage up into the double digits that would be a success.
Transmission - As far as I can tell it is a 4R70W. Gear...
I have a 1996 Ford E350 with a MFI 7.5L V8. This monster is renown as a gas guzzler and I am researching ways of improving gas mileage while making it more efficient and getting more power. One of the things I am considering is installing headers and a new exhaust system. My question: Is a Y...
