Not only that, they're pretty tapped out on power ability. Add any kind of forced induction on them and they go boom very quickly. To add to the discussion we had on your thread about the air filter being inside the trunk and getting it's source of air from the trunk vents. Here is a great picture of why that's not the best idea. On a good note, my motor seems to idle better with a clogged air filter. lol
I can definitely see how those filters would get dirty quickly if there's nothing between them and the cloud of speed you're kicking up. My money is still on pulling air through the trunk lid. I wonder if a stop gap would be to *cough* duct tape some generic filters in place over the vent openings. Cheap filters will probably breathe just fine and may at least cut down on the dirt storm inside the trunk.
Rough idle is a sign that the design is working! Lean her out and squeeze out that power baby.

When the owners manual says that the laws of physics can't be broken by this car, I took it as a challenge...
At the last race it had become real difficult to get any power down. That's always a big problem with RWD and the main reason RWD vehicles are typically slower in the dirt. I decided to move the battery as far back as I could. I also plugged the holes in the trunk so dirty air couldn't get sucked in to the air filter.
Thanks to Truegear's build thread, I upgraded the single toyota tercel radiator to a much larger radiator built to fit a chevy impala. The new radiator with fans was less than $300 and surprisingly well built. The latest improvements helped immensely and I walked away first in my class of 15 and second overall, losing only to an AWD subaru.
I picked up my next race car for $3000. It's a 2000 996 C4. I'm not quite sure what power plant I will end up using. I'm leaning towards a LS because I really want 400hp and 400tq. Not going to get that out of a M96. This project will be on the back burner for awhile as I'll be busy building my new shop. It has 2500sqft of enclosed space and an additional 1000sqft of cover.
