Naturally Joe, I would think that everyone reads the forum and is aware that people post their opinions. As you did. And as I am about to do.
Your "facts" 1-4 are not all proven to be true - yet.
1. reduced engine costs - how? Development will be more expensive with SIRs in place. Why?
But when the maximum intake airflow speed has been reached, improvements in the combustion efficiency and reduction of friction losses can still yield more power. So, we change from getting maximum hp from the motor to optimizing everything under the effect of the SIR. Sounds like a lot of ECU time and dyno time, coatings, bearings, and other yet unknown tricks to get every last 1/4 hp out where as before one was satisfied to get every 1 to 2 hp out.
2. closer racing - Maybe, but the SIRs aren't as straightforward as they were thought to be. And, we'll need different SIRs tested on all manner of engines to level the field. Small motors will need slightly larger SIRs than calculated to make up for torque deficiencies, big motors will always be suspect on making too much torque, etc. Who is going to check all this? Who will make sure it is right? The ITAC is hard pressed to get weights right. There is no time, manpower, and money to handle all the testing that will need to be done.
3. ok
4. I'd say lead is consistent. It'll reel in the fast cars and can be adjusted cheaply and easily. Too much? Take off 100lbs. Too little? Add 100lbs. I guess count me in the class of disbelivers that don't buy that the addition of 300lbs of weight will take a uber competitive car, a winning car, down to a unracable box in one fell swoop. Yep, it'll increase wear a bit, but there are lots of cars that wear brakes, pads, and tires out extremely quickly and as far as I know the BMW was given an exception by the ITAC or CRB from this possibility.
I don't think you are going to like the proposed ITU class. The cars are going to be too heavy to your liking, but, fortunately choice is free and you don't have to race in it. Just like you don't have to race a BMW if you feel it weighs too much, wears things out too quickly, and costs too much to campaign.
