    Honest question which may be answered by Andy's answer...

    Why can the S2000 run at ITR spec but the RX8 has to add weight? Why can't I run my RX8 as an ITR car?

    Stephen

    PS: Jake you are spot on for IT gains and stock they have 170-180. Biggest issue with any Rotary Dyno number is that none are really set up for them specifically so the user error is pretty high.

    Well, you know how I know, right? The thing committee guys do called homework.

    Displacement. The "displacement equivalency" of a rotary engine is 2x, thus your "1.3L" Renesis is actually considered to be 2.6L and is thus ineligible for STL absent the specific allowance(s). You are allowed to run it in STU as an ITR car.

    In my personal opinion, the philosophy of Super Touring engines is one of allowed intake/engine modifications and classification based purely on displacement. Thus, in my mind an unmodified rotary engine does not fit into the philosophy of STL on two fronts.

    But, obviously, that's only one person's opinion.

    So Greg answered a bit but let me simplify for you. There are only a few ITR cars that fit the allowance rule for running in STL in IT-spec. Has to be below 2L. Since the rotards are considered 2.6, they aren't eligible for that specific allowance. However, they did make a specific allowance for the RX-8 (or any Renisis-equipped Mazda product) at 3000lbs. Why, I have no idea, but that is 'better' than not being able to run in STL at all if that is where you want to double dip. Most IT cars go to STU and some even to STO.

    Are you asking about running the S2K or RX8 in ITR trim in STL or STU?

    Greg (et al.) - Can I get some guidance re: what specs you need in order to consider a specific spec-line request? What kind of documentation counts as sufficient evidence on which to base a decision? I'm looking at the Euro-spec VW ABF 2.0 16v, as found in the continental GTI of the same generation as Pablo.

    Thanks in advance,

    Kirk

    Not yet. We need to get the general idea approved before we can get to the specifics.

    My sense is that we're going to need power output specs to ensure it does not exceed expected guidelines for the class (whatever those are), and then relevant scrutineering specs so it can be tech'd (e.g., intake manifold design/part numbers, throttle body size/part numbers, valve sizes, some idea of stock port configuration, etc). But that's just a WAG on my part right now.

    Let's get buy-in on the concept then we can work on the details.

    Your thread over on RRAX brought about a response from Mr Keane (of the CRB ), who seems to indicate he's in favor of the concept.

    I really really hope they don't do the 5% off strut cars to equalize performance to RWD cars. Right idea but wrong order. Get big issues resolved, then do the smaller bits.

    I AM encouraged though, to see a bit of a break from the Everything is equal, just pick your weight and race mentality. Allowing that chassis selection does matter, and wanting to adjust for that...by genre...is a good indication that they are thinking that it would be good to get more cars on the same relative footing.

    You are perfectly welcome to install a 13B in the RX8 and run it at the 13b weight. There are options. Everyone would like there car to fit inside the Super touring Box neatly and cleanly. It just doesn't work that way.

    I for one know of an RX8 that will be running ST in GLDiv. Lets see how it does and if it really is that far off, then we can re look at it. I suspect it will do just fine.

    Chris,

    I was confused because I thought other ITR cars could run in STL with ITR prep levels. Some others on this site posted they were going to run an S2000 under ITR prep rules. That is what didn't make sense to me.

    Sorry, Back on topic...

    But you understand the rule now right? Cars prepped to IT spec that are 2.0L and under. The rotaries are classed at 2.6L.

    I'm just a dork but for the life of me, I can't find the "feedback requested" item re: non-USDM engines in ST anywhere... Help?

    As Andy said, Stephen, The STAC has decreed that they will use the 'double displacement' standard for rotaries when they class them in STL. So, a 1300cc 13B is the piston equivalent of 2.6 litres.
    And STL is limited to cars less than 2.0 litres. No ITR BMW, for example, may run in any STL race.
    But, a 2.0 litre ITR S2000 can run in it's IT configuration as it is 2.0 litres, but since the S2000 is on the chassis exclusion list in STL it may NOT run in STL configuration.

    Follow? I missed it at first too.

    If that Huffmaster kid is driving, it won't matter how far off the car is.

    Still wondering what rule or principle of the SCCA we're upholding by only allowing "in family" engine swaps, whatever that tortured interpretation is.

    I would like to see more of what Ron is talking about... complete engine swaps. set the weight based on engine adders, suspension adders and maybe a few other things and let them run! Use any engine in any chasis! That would be cool and I bet we would see some cool cars to
