Any reason we lost the injectors on the Mini? Not sure how we catch a Solstice without fuel. Have one and building a second one so curious.

You didn't. Injectors are free in STx, it was struck as a redundant note.
Back story is that there used to be a line there where a combo of some pulley (JCW?) required stock injectors, and one pulley (stock?) allowed open injectors, but when that combo was removed the redundant note was not.

Did this note just make IT a legal national class that will allow you to qualify for the runoffs?
Production
1. #12279 (Philip Royle) Allow IT cars to run in Production in IT trim
Thank you for your letter. Add 9.1.5.B5.: 5. Any Improved Touring car meeting all the requirements of ITCS 9.1.3 may compete in the Production class in which the same make, model and engine displacement car is classified. For Improved Touring cars competing in Production, the level of preparation and modifications will be as determined by ITCS 9.1.3 and not by PCS 9.1.5. This is intended to allow Improved Touring competitors to become more familiar with Production to assist them in determining whether to modify their cars to meet the requirements of PCS 9.1.5 and also to permit Improved Touring competitors to compete in all events open to Production cars.

the classificaton of the B18C5. Not quite sure why the 1" porting note has to be there. Is that not the rule for all STL builds?
Also why more weight for the RWD? didn't a FWD qualify 3 and 4 at the runoffs?
Good to see my request got through.

Why the hell is someone asking for a VW Passat to be classified in Touring 4?
Early (1997) Type R B18C5s were hand-ported from the factory. Subsequent B18C5s were subject to a CNC clearance process (something that typically may be part of a good IT/STL-level engine build anyway). The CRB would not approve (and I would not have supported) the engine if we allowed the factory porting in, since it would not be able to be scrutineered (what part was done by eunich ex-Ninja Shinto monks, and what was done by the competitor?)
That note is an exclamation/clarification that the ported B18C5 engine will not pass scrutiny in STL. Any porting work, factory or otherwise, is prohibited. If you've got a hand-ported '97, you'll need to either get one that is not ported and/or start with a replacement casting (e.g., B16A/A2/A3 head).

1. #11724 (Willie Phee) Classify Acura TSX in ITS
The CRB requests member feedback for this question. Please submit letters to crbscca.com. Should the 04-08 Acura TSX remain as currently classified in ITR at 2760 lbs or be moved to ITS at a weight of 3175 lbs?
---
Bring it on into ITS with 205 stock hp @ 3175 lbs and some 15" wheels. Hoosier guys will love it.
tGA - stupid (maybe?) question:
STL now has weight penalties (understandably) for certain engines, RWD/AWD, etc... are these applied successively, or are they summed before applying the cumulative % penalty over the chart?
e.g. the B18C5 has a 2% penalty. if RWD this would be chart *1.055*1.02 (1.0761)or *1.075?
at 1800cc this is 2430 chart, 2615 as successive, 2612 as summed.
I recognize it's 3lbs in this instance, but that's enough to get bounced at impound.
I would disagree, Eric. STx is an engine-centric category, and the engine weight is the baseline for everything. Additions for specific engines should be factored into that baseline. So IMO you'd tally up all the stuff for the engine, and that's now your new base weight for the chassis it's installed into.
Example: B18C5 Type R engine installed into an S2000 chassis. Engine is 1.8L so 2430 pounds. B18C5 get +2%, so 2479. Gets installed into a RWD S2000 chassis, so +5.5% over 2479, thus 2615#.
If there's reasonable disagreement in this, then it's something we should clarify/codify.
- GA
don't wait for disagreement, codify it NOW before there's a problem. again, that problem is AT WORST 3 lbs with a 2% engine modifier but if this system becomes a more common practice, you could expect that delta to grow.
and as I said above, 3 lbs is enough to bump you at impound, and it's 3# higher the tGA way than the tEH way. just state the order of operations, and do that every time you add percent weight changes to other allowances.

Yes, you beat me to the punch. The revised Prelims are now up.
...are posted:

So it was requested that the renisis to be eliminated from STL but it looks like it just lost weight and then they added a restrictor? And the type r engine that races in ITR with the renisis is being added?
Greg, can you clarify? I am searching for an auto rx8 to possibly do a few swaps to run in STL but again I am thinking of sticking to IT until STL gets sorted out in a few years.
Thanks, Stephen
Another rules nerd question: STL fuel cells. A car built to IT specs can have a non FIA cell. A car crossing over to STL needs a FIA cell?

Lemme try! Before Greg gives us the real info:
Stephen - yes on your two comments. Greg asked for the Renisis to be removed, and the committee decided that they would just handicap it instead of that. Lower weight but I am assuming an educated guess on how much power they took away.
The addition of the Type R engine includes a weight penalty assuming because the cam spec is outside the rule-set? Interesting.
Chuck - your fully IT compliant car can run in STL provided it meets the engine size requirements (non ITR) no matter what rule is or isn't specifically compliant in STL. It just has to be 100% IT with no mixing and matching or rule-sets.
On edit: I wouldn't put a dime into an RX8 for STL right now. There is committee issue with the motor design, and RWD adders keep on rising. A good plan would be to run one in ITR for a couple more years and see what happens...but just like in ALL National classes, you win the runoffs, expect a lead trophy (or RP or...).
