I'll take some pic's and post them up tommarow, it's hard to explain with a keyboard. It wasn't hard and I just followed what Christ recomended earlier in this thread. I just drilled holes thru the round part and bolted it on.

Man, this new weather is so nice.

My tank just went up from my normal 4 mile drive home from school. Starting temps were around 70. Just pulled 35.6.

I've actually kept my tank right around 35.5 (started with ~100 miles highway) with these small 4 mile trips.

Also, have "small" side skirts on. Maybe a 6 inch tall piece covering top half of the wheel well.

Here's the only pic I could rustle up. I didn't use any of the holes under the bumper. I just drilled small holes, for the bolt to fit thru the round part, then drilled a larger hole thru just one side for the bolt head to fit thru. I just positioned it out near where the bumper turns under, at least at a point where it looked decent.
I think your weather gets here tomarow. Can't wait for it. It's been 40 in the morning and 50 in the evening. Last tank suffered cause of some drag strip fun, but still 37mpg

I've been pushing to get 40+ on this tank, we'll see how it goes. The peak of 39.8 was done in colder weather, however I was driving like an extreme crazy man slow. People were just honking at me and such, so I've sped it up a bit and no one seems to be bothered as much, but the mpg's fell a little. Seems like the heaters might be helping by approximatly 1mpg, judging from the fuel logs. Nothing conclusive though.

We need some pic's of the "mini skirts"

Pic? I don't see a pic...

It was tooooooo big, now it fits

LOL - I forgot about the Home Depot lip :P

Tygen1 · 03-18-2009, 01:39 PM

Home Depot rules! $16.74 for two cars worth of Lip's. I've already got a knife in my glove box if it ever gets damaged and is dragging. Just cut it right off

Best tank since October!

Changing the oil this week, hopefully. 7k miles .... haha.

You'll be over 40mpg in no time, the summer gas will be here soon and so will it's benefits

I'm still stuggling to get a 40mpg tank....I've changed my driving habits and it hasn't helped, however I found a BSFC map for our motor and am trying to use it on this tank for Pulse and Coast to see how that works. Seems to be working so far.....
Chart attached: First one is baseline without EGR the second is with 10% EGR, which is probably close to what our's is doing. Nice wide band of rpm and load that we can get good mpg's. Folks may be flocking towards the ZX2 after seeing this

I think last year, I instantly went up somewhere between 2-4 mpg with summer gas.

Unfortunately, those charts mean nothing to me as I haven't go a clue what any of that means...
