See this is what I'm thinking; Sure it may produce more downforce due to there being an increased low pressure zone, causing it to slip under the car faster than it did before. But in the end there is still far less turbulence because of the amount of air going under the car; and because of the increase in speed of air underneath, it doesn't allow turbulence, and creates pockets for the air to flow more directly.
Ford made a fantastic little engine with their 1.8 N/A diesel. With nothing but tick over it was able to pull Vanessa up a rutted hilly dirt track. DIESEL POWA!
It is a very short first gear, ~20mph is where it tops out. No idea what it idles at as I don't have a tac, but it is standard 1.8D, so I'd assume ~500-700rpm.
My old nova used to do about 35 in 1st, just over 65 in 2nd, about 95 in 3rd and went off the clock in 4th, although that may have been because i replaced the blown up 1200 lump with a suitably tweaked 1400 engine, with a decent rejetted twin choke weber, and left it on the std 1.2 4 speed box, god that thing used to rip
As with all diesels first gear is ludicrously short, because it is a rolling gear. Once you get moving you're supposed to slip it into second. When in an unladen vehicle it seems pointless, but once some weight is in the back it means you don't torture the clutch.
You've gotta eat through tires on that thing then. I can't go full throttle in 1st. Either the car doesn't go anywhere once I get past 2500 rpm because of the TC (which the tires still spin) or the car just sits and lights the tires up without the TC.
It's 2nd gear that I give it the go juice. Even then, the tires will start to spin when I reach above 2500 rpm half the time. They are pretty dang sticky tires too. I don't know how it will keep from spinning when I finally get some reasonably priced tires that will go in the rain.
There isn't a single aftermarket diffuser that has been made for our cars; there is one for the mazdaspeed3, but it is ugly and just replaces parts.
As far as functionality goes.. it at least covers the gaping hole we call the underside of the bumper. I wouldn't be surprised by any means if it helped just some.
made the template but having a few tiny problems with it; just because A the template was made for putting a texture on it in a 3d program; not spread out perfectly into a 2d shape.
As you can see, there is something holding the outside part down, not sure what yet, but it clearly isn't lining up with the bumper either so either way it has to get redone. I just put it together and didn't have my car near me so I wasn't constantly checking it.
So for anyone that has made one.. have any tips or anything on how to go about making a mold for something like this?
i havent made one,only modified mine to fit. but to hold it to your bumper you'll need to make brackets from plastic at least if not aluminium. it wont be easy thats for sure.just coz u prolly dont want holes in your bumper right?
