Andy, and everyone, thanks for the great work.

Am I reading this right -- no weight on the E36, but a bigger restrictor?

The 944s got the help they need. Hope that brings them out en masse.

As to the SIR on the BMW...there were two options:

1. Raise the weight of the E36 325 to where the process said it should be
2. Restrict the HP of the E36 325 to where the process said it should be given it's current weight.

SIR technology has been proven in other classes. It's not so much the size of the RP in this case as it is the size AND design. Mathamatical calculations are being used (and verified) to size the SIR. More info can be had with a little help from Google. PLEASE don't think this is just a simple reduction in restrictor size. Do the research on the technology before you simply state it is x% smaller, etc.

The BMW's should not get any slower if they were using a proper RP this year. This technology just prevents cheating and mandates the HP levels, given a weight target. As with any RP however, it has much less effect on lower RPM charateristics (like torque) than it does higher RPM charateristics, like HP. The BMW should now fit the process without potential for monkey business. If it is still the car to have in ITS, then it is the car to have. It fits the process...period.
