    Hello James, whats your take on the "unrestricted" 2.5 in the 323 e46, can it be made to overcome the extra weight? chassis should be better?

    Anyone got a picture of these plates? Who's received theirs so far?

    I race two classes; ITS and production class that doesn't require a restrictor plate. How easy is it to remove the plate and replace it? Will I just pop-off a hose, or must I un-bolt the plate from the output side of the the throttle?

    Steve,

    Nice talking with you on the grid Saturday. Carlos' car looks very good. It seemed really fast too. See you soon.

    Jim

    Jim, classic IT.com post. No mention of the fact that MVS easily won the race (not sure Mike even broke a sweat), or that his RX7 has regularly run 2 seconds a lap faster than his best lap in that race.

    that is true bruce .so please no more weight or resrtictor plate.
    mike won the race because a car about to be lapped and not looking in his mirrors was surprised by mike passing him .so the guy spun in front of carlos he took evasive action to avoid hitting the guy .needless to say mike was gone by that time.but yes we got our a-s kicked.

    ok, maybe my original post was a little "tongue in cheek". I've revised it to correct my evil ways.

    But, Carlos ran a 2"33.9. That is a respectful lap that either you or I would be happy with. And, with the further suspension tuning that Steve mentioned, the car should get faster (low 33's or 32's maybe). So, from my point of view, the restrictor plate did not take the ability to win away from the E36. The suspension development will put that car right with the other fully developed cars. That is where a top notch car should run.

    I realize that none of the E36 guys are happy about the restrictor plate. I'm sure you realize that everyone else in ITS is happy about the plates. Would you expect it to be any different? I don't.

    Jim

    carlos is willing to spend the money it takes to develop the car even further with the restrictor plate and the only way is with the suspension.i am not a bmw engine guru.i know a little about suspension so that where i develop.

    > very easy to install

    I'm not much of a wrench. The plate arrived and looks great, but I haven't a clue of where it goes and it didn't come with any paperwork. At all.

    Am I to bolt it on the intake side of the throttle body, or the manifold side? I don't think I'll be able to remove it or add it when the car is hot, between classes.

    Maybe it'll actually be obvious when I have time to have a close look at the car.

    its obvious. between manifold and tb. bmw gasket on one side and something like hylomar on the other to seal it. if you have q's, just call or email bimmerworld.

    The intake should be easy to change between sessions. There shouldn't be anything to burn you around the intake.
