Alternate title: Group 2 by any other name may not be Group 2.
Greets all,
As a large number of 2WD teams from ALL OVER will be in Idaho, I just want to take a second to break out the classes and maybe clear up some of the confusion as the CRS Competitor Liaison. If you don't want to be hit with a competitor inquiry before you even get to tech - this is for you.
Idaho is a NASA sanctioned event. NASA has car prep rules, but is a sanctioning body.
Idaho us a USRC championship event.
* USRC two wheel classes = OPEN 2WD, PRODUCTION 2WD.
If your car is Rally America Production Legal (Bone Stock, etc.) you are eligible for USRC Production 2WD. EVERYTHING ELSE is OPEN 2WD. Got it? Easy.

Idaho is a Max Attack Championship Event.
* Max Attack brings GREAT exposure for us 2WD guys.
Their class is anything 2WD at 3 events each year. Register and you could win a cash prize based on how well you do. Sure, you may have a slow 1.5l - but turbos break.

Idaho is a California Rally Series Championship Event.
* CRS two wheel classes = CRS-5, CRS-2, P-STOCK.
- If you have a "RA Group 5" rally car - you are in CRS-5.
- If you have a "RA Group 2" rally car - you MAY NOT be in CRS-2 !!!
From the rules:
"The table of adjustment multipliers below will be used to determine a vehicle’s adjusted displacement. All factors that apply to a given vehicle will be used. As an example a 4-valve engine with variable cam timing would have a total multiplier of 1.32 (based on 1.2 * 1.1). All 2wd vehicles with forced induction or rotary engines will be placed in CRS-5. Eligible vehicles with an adjusted displacement of no greater than 2400 cc will be placed in CRS-2 while those above 2400 cc will be placed in CRS-5."
Engine Characteristic Multiplier
4 valves per cylinder 1.2
3 valves per cylinder 1.1
Variable cam timing 1.1
Diesel Engine 0.8
Pushrod Engine 0.8
- If you have a 2.0l 16 valve motor you are in CRS-2.
Anything above that and you are in CRS-5.
So a 3.0l motor (no matter how much your car weighs) is NOT eligible for CRS-2.
Update your rally registration accordingly.
- If your car is Rally America Production Legal (Bone Stock, etc.) you are eligible for P-Stock.
- If you car doesn't seem to fit in CRS-2 you may want to have a look at the CRS P-Stock rules:
"Internal parts are free with the following exceptions: 1. Stock block must be retained in the stock location. 2. Dome-topped pistons are not allowed unless they were stock on the specific body. The stock induction system meaning the intake manifold, carburetor, or fuel injection system and exhaust manifold must be retained. However the stock intake and exhaust manifolds may be modified. The stock carburetor may be rejetted. The choke mechanism may be removed or fixed open."
There are lots of other restrictions on a P-Stock car, but it means that you "could" have a 2.2l 16 valve motor (breathing through the stock manifold) and run in P-Stock. In this example you would be in "USRC Open 2WD" and "CRS P-Stock" with a car that may be fine as "Group 2" in a Rally America event. So it's worth your time to take a look at the rules if you are in this position. You may just need to slap on a stock manifold? If only...

Idaho is a Pacific North West Rally Championship Event.
Please someone from the PNWRC chime in: Are your classes equal to RA classes?
Here again I will mention that: Just because you are in Group 2 PNWRC you may not be eligible for CRS-2.

Any questions?
GO two wheel drive! Be smooth, DON'T LIFT!
