Okay boys and gals, you'll need to sit down for this one.
I thought I put numbers in wrong, but I haven't!
So here you have it...two day work commute setup with new pulley:
a) wheels open (no tape)
b) no skirts,
c) temps in the 40s-50s,
d) weather is reasonable - no rain, overcast, slight humidity.
e) full tank of gas
f) spare tire and trunk bits re-installed
g) tires inflated to 33psi front, 34psi rear (down from 38 psi all four)
h) 5w-30 Castrol, previously 0w-30 Mobile eco-oil
Result: 136.8 @ 4.753 gal of gas = 28.78 MPG!
Now this was an honest try to get high mpg, I was squeaking the best out of the car. But that matches some of by best results I had using the eco-mod tricks and gadgets.
That being said, this was done because I ordered an unequal length "race" header. The header has definitely been a power adder to the car. and I may have more than made up for the two days of green mileage. I will fill up on my way home Monday night, and stop for gas on Wednesday. We'll see if we can get a good comparison between before and after header.
The sad part is that I needed to remove my front grill block. I had "plowed" someone's recycling bin during winter. The resounding effects have now creeped up and the fiberglass is flaking apart from the impact zone. So off it had to come. It makes me depressed that alot of the hard work has come undone, but thats life! It will make it a huge challenge to see if I can match/near match mileage without grill blocks and the header installed.
