Was talking to ITR-585 at the latest socal meet and he was saying that after adding his jdm 4-1 header, he had bumped up his gas mileage considerably! like from 26mpg to 30mpg. has anyone else experienced the same? in the end of it all, the mod eventually pays for itself no?

kepani-who's making it harder NOT to mod his car...

 

If my math is correct..

Say a gallon of premium costs $1.75. Say you increase miles per gallon from 25-30, on a modification that cost $500.

So, ($1.75/gallon)/(25miles/gallon) = .0583 dollars/mile
Then, $1.75/30 = .0673.

A difference of: $.008974, we'll round up to $.009/mile

So, $.009/mile * x miles = $500 (how much the mod cost)

So if you drive 55555 miles, you'll pay for your $500 mod.

.. I think this is mathematically sound reasoning ..

I see why you have that Screen Name now.....

 

I was almost done writing it out in one formula, but I figured I had better explain what I was doing too..

Of course, this formula is dependent on the price of gas and how much mileage improves.

 

LOL...that's just what i was thinking!

 

Just mod your car. Never hurts to get more mileage and power at the same time. Just watch your foot.

 

i may be in the market for a jdm 4-1...
from the results of the great header test, the jdm performs well and is much cheaper than the other spoon/mugen types. however, i guess it would depend on what my plans would be down the road huh? adding cams, etc. would warrant a spoon/mugen/hytech type...

am still wondering about a spoon n1...but i am kinda discouraged by the noise issue...
