Hehe, so milage problem solved, a turbo kit for everyone:D

Oh yeah, it's been about 500 miles now. Averaging 15mpg. 17mpg on my road trip down to Jeff's place for the dyno. Which is very strange considering that I was getting 10mpg before the turbo. Mazda really has the stock maps running tooooooo rich.

Jeff just take your garden hose inside the house for a little bit then bring it back outside.

193.44ft-lbs @ 4643rpm was the max according to his calculations
190'ish torque was availible starting at about 3100rpm al the way up to about 7000rpm. So now you know what I meant when I said it had a bit more kick to it at launch.. no wonder I can go sideways in 1st-4th gears if I try

You need to have an intake tube in the airstream that then feeds a larger expansion (or more appropriately and compression) chamber. A way to do this would be to take a 6" pipe and feed it directly into the oncoming air. This pipe then feeds into a "box" where the area expands many times over the area of the inlet pipe. This box can contain the filter and then go on to the engine. When the air flows through this large pipe from the forward speed of the vehicle, it enters this chamber and the expansion in area slows it down. When it slows down, it compresses a little. This compressed air is what the engine is actually breathing. This is "ram air". How much of an effect this has is based on 2 things. The most important is vehicle speed but the next one is engine rpm. Obviously at 100 mph at 5000 rpm, the engine needs less air than it does at 100 mph at 9000 rpm. The amount of "ram air" available would be greater at 5000. Postive pressure is positive pressure though and a gain is a gain. For everyday driving though, you won't benefit at all. You might, maybe, possibly, on a cold day, see a slight amount of positive pressure at speeds as low as 75 mph but it probably won't be enough to feel. At speeds up over 150 mph though you might get a couple psi of "boost". In 1979, Racing Beat found that on their nonturbo 13B Bonneville Land Speed record RX-7, a "ram air" setup done in this fashion added 3 mph to the cars top speed. It hit 183 mph. Without "ram air" it would do 180 mph. Remember that the effect is much greater at high speeds. How much of a benefit does a properly setup "ram air" system really have on the street? I'd say little to none. At least not at legal speeds.
Mach 10?! "not at legal speeds" indeed

Maybe I can aim my 50,000 BTU propane heater at the whole thing for an hour or so....

Unfortunately, the tach in the RX-8 lies just like the tach in every other Mazda.
When he saw 8200 or so on the tach, the actual RPMs were only 7800.
No matter. Even though the absolute peak power might have been at 8000, I think we can all see the story from what we got. :D

Ice it up real good until the swelling is mostly gone then switch to mild heat. Take a bunch of aspirin (2 at a time every 4 to 6 hours) until you can get it X-ray'ed.
Ugh...

Oh yeah, I don't take asprin.. I prefer ibuprofen myself.. it's a better anti-inflammatory.

On another note, here a daytime pic of the MS front bumper. YOu can see the intercooler a bit easier now.

p.s. I know.. I need to adjust the angle on the foglights.. they are pointing too far down.

Nothing is hanging down.
