Mmm, that's annoying.

Thanks red91sit. It didn't end up taking THAT much time, and it was spread over a few weeks, so I'm sure you can squeeze in some mod time. :-)

zpiloto and Gary, I'll have to experiment with grille blocks. kps, constant fan running would be a good thing to avoid, huh? :-) I'll be watching out for that.

MetroMPG, I was surprised that the undertray made a difference in the noise level. I'm glad that you confirmed that others have noticed the same. It would actually be easy to add more sound deadening to it. I hope that you get good results with your air dam experiments.

CarloSW2, I'm glad that it was the right level of info for you. Once I got it assembled, I looked at all the wingnuts and thought "what was I thinking?" But it really did make it all go together easier, which is pretty valuable when you're lying on your back under a car.

looks real clean keep up the good work

My Civic hasn't had over heating issues at all with it engine belly pan. Only thing I can tell it does for me is help to keep the engine compartment cleaner. I cant tell its done a thing for mpg.

is it the lower u go on the air dam the better and more force on the front end, is there a wing for the 87 crxs on top of the hatch

[red91sit]

Not neccesarily, you go too low, and You increase frontal area causing more aerodynamic drag.

i tried putting tape on the front end of my crx and with-in a 5 miles period the temperature went up, i had to take off the tape, i do tho havea small 2 inch gap that gets to my radiator eand gets air, but was wondering if i could just make some holes in the front nose panel and re tap up the lower part

Bill in Houston,
I think you did a great job.

I drive an "89 Volvo with OEM air dam that was standard on those cars but I hope to add an extension downward based on what you showed.

Going off-topic - - -

I put in a grill block this past Friday. Tested a full block the day before, looked like a gain of 1.75% with full block in about 35-40 deg. F temps.

For grill block,
I wanted to leave small openings spread out over grill area rather than one single hole. I used lengths of dark gray foam pipe insulation stuffed between the grill slats. I thought it would not show but it's very visible. Insulation is 3/8" thick; squeeze flat and stuff into slot space. Ended up looking like a decent home-brew job. Don't know yet if I'll need to remove it in hot weather. Probably.
