Why would you think we would NOT apply as consistently as we can?
C'mon now, some of this is getting silly.
We've had the DW discussion on the committee. I don't think the committee's opinion is going to change. In my opinion, we are starting with "doing it right" with the Vette. If we do it your way we are going to see the weight change on that car two times over a six month period or so, and the CRB is going to ask (rightfully so) what the hell we are doing.
Yes, there is a downside and yes, there is a bigger picture than this one car.

Where does the RX8 fall in your new number crunch? Need to decide if I get new glass or lexan.

Struts up front, multi-link rear right?
Shouldn't change at all if so.

RX8 is Mazda double wishbone upfront if I'm not mistaken. Multilink rear.
So with the RX8... did we get the 100# deduct for lack of torque?
I REALLY wish they would use the SCCA forums to post HOW a car is classified and WHY. Not the process but list each new classification similar to an online journal for ALL members to reflect back on. Then we would have all known which cars got a 100# deduct. I honestly had no idea any cars got that.
Ron you are correct. ITAC Should I plan to add 50# or 25# since the car is only 50% DW?

There is a lot of data on that one and was set with real world numbers. It won't be changed -- I'm pretty sure Lee and I will be adamant about that as it was probably the most discussed car in the ITCS after the Miata and the MR2. I'll check but I'm pretty sure it was classed with the torque deduction.

I don't have the data from before the corrected classification went out feb '09, but it looks like a known HP number of 262 crank was used (translates to ~215 wheel), as was the -100 lbs for low tq. being consistent with the ops manual would add 50 lbs for suspension. otherwise the classification wouldn't change.
and like I said - I'm goignt o run my numbers WITH DW, without DW, and with and without strut and FWD struts. it's a lot of work to build the data and spreadsheet, but once it's done the core numbers my spreadsheet makes the varients easy. we'll run them all and evaluate the results agains curb weights, pwr/wt, tq/wt etc.. there will be no more than ONE package of recommended changes to the CRB.
And you can tell them the truth. That you went by the flawed Ops manual, didn't recall how cars were classed, and applied an adder when the class didn't currently call for it.
So you humbly admit this, bring the one car in line until the ITAC and the CRB align on a re-do of the whole class. Why? Because the simple fact is you should be considering a strut decuct at these weights instead of a DW adder. But that is just a time and committee thing, I don't so much care either way as long as the class is aligned.
It's really the most simple and fair thing to do. I can't see how you would see it any other way that to avoid a slightly embarrassing situation for the ITAC, unless the ITR redo was published in the next couple months, but that ain't how fast things can get done. ESPECIALLY considering the perceived desire of the ITAC to stabilize the rules for a time-period.
RX-8 is DW front.

Stop with the flawed Ops Manual. It's the best thing the ITAC did besides the process itself (and I'll ad you were initially opposed to publishing the Process). Josh did a great job with that.
What was flawed was the reason the unwritten rule of "no DW for ITR cars" came about in the first place. "All ITR cars" do not have DW. Another flaw was using a "static" deduct for FWD and them dumping it for a percentage after a lot of cars had been reweighted. I was apart of that and acknowledge being a part of it, and we are trying to fix things by being consistent and doing things right from the start instead of changing them on the fly or fixing them later.
You of all people should know we only have a certain amount of ability to change things before the CRB (rightly) starts to wonder what we are doing.

Why are you getting uptight about that statement? I was on the committee when we were revising it, it IS the best thing that has happened to IT in a while...but that doesn't mean it's perfect. And by that I mean that when it went to 'print' it wasn't completed yet. You guys forgot to write in what the process entails for ITR cars. It's ok, but it's fact. And I was in favor of publishing that document once we got it done - ONLY if it explained every in and out of what the ITAC could do...which is why it took about 9 months to get finalized. A quicky 'process' blurb would have only created more questions than answers.
Nobody said 'all ITR cars' had DW's. What was said was that the core car in ITR had significantly advanced suspensions to not warrant the separation, except when it was a strut-based FWDer. That was the process for ITR. Nobody codified it before it went to print, and now you are classing cars differently than the entire category...due to an error. It's OK, we acknowledge it and we decide whats the best way to fix it.
I submit again simply that you suck it up, pull the 50 back off the Vette and hunker down and strategize on what you want as a committee. +50 for all advanced? +50 for just DW's? -50 for all strut? -50 for strut and FWD? The ship won't turn in say, 6 months, so don't hang the new classification out to dry. I don't care how 'little' you think the weight is. My inbox is full of PM's asking me to justify +150lbs for excessive torque. It all adds up.
I know fully what the 'old' CRB will accept and not accept. I know a couple current members who call me all the time asking about certain issues and I am confident that when you lay out a good case for something, they will get it. I also know that doing what is right is more important than making one or two CRB members happy because they have better things to do than deal with IT.
Let's end the debate, I am sure we know each others position. No further progress is to be made. Time to go build that 300whp cease-fire V8.
Sounds like they didn't do much research on their C4 vette choice before commissioning the build. Of course it gets a weight adders for large displacement/low-RPM-power.
300 whp I don't believe. But I suspect you'll see north of 240 whp, with a torque curve that is flat like my desk and hitting the 280+ mark.
I am SURE they knew the 100 or 150 was coming. but I bet the 50 for DW surprised them.
(My recollection on the ITR tq thing was that it was discussed for MONTHS....like over 6 months.. What IS torque, how do you ID it? how much is too much? Is it the tq CURVE that counts? How can you FIND a the tq curve for every car. (if you can't then it's not applicable ), is it a relationship to HP? Do you stick a low hp car with the penalty if it has high tq? Or just high hp AND high tq cars. What about the transmission? LOTS of debate.
Then there was the 'if it has a lot of tq, does it get a graduated adder?' question. 50, 100, 150.? If so, how do you decide? What are the break points?
In the end, I think the committee decided it was too difficult to identify levels of tq, and a procedure for that was deemed impossible with the resources at hand, and decided that it was one of those things you knew it when you saw it, but couldn't really describe. (This was around the time I left the committee, I think, so anyone with better facts feel free to correct me)
I think, in the end it was just simplified with a "we will know it when we see it, and if we see it it's getting 150" kinda thing.)
I know a lot of that discussion IS in the notes on the board
