One thing the PAC may want to adjust (unless this is intentional?)

There are three listing for verbiage change in camshafts in the TB. These changes state specifically (for example):

Comp. Ratio limited to 11.0:1. Valve lift limited to .425”.

The words "limited to" were added, and "max" was stricken. This means that these cars can only run the listed valve lift, without deviation. This means that anything less than that is not allowed.

Is this the intent? If so, I'd find that hard to understand...

Edit: GCR Appendix G.2.11 (p146, Dec 2021) states, "Valve lift is absolute maximum." I'm curious what the purpose of adding "limited to" is; seems confusing and (at best) redundant.

Oversite for sure.
What did I miss about the Spit 1500 and Spridget 1500? Are the engines the same? Why would the weights not be?


Glad to see SCCA trying to keep racing cost in check by tossing a carrot to Prod racers running 100TW tires.
Not even 2%?? Really .

"Comp. Ratio limited to XX.X:1. Valve lift limited to .XXX”."

That has been the standard verbiage/structure for listing those spec forever. Look through the Prod spec lines and you'll see it. The change you're referencing in this Fastrack was only done for consistency to this. The issue you're taking with it is one you could've had ten years ago, which is reading the word "limited" as "limited in option" and not "limited in max value". It's a point one could argue I suppose, but I think everyone understands the intent, and it's not anything new.


The PAC has zero interest in trying to balance the ability of one tire versus another through weight adders. Nothing in the rules stops you from using those 100TW tires, or a 200TW tire, or a DOT-R tire, or a bias ply slick, or a radial slick, or a Goodyear slick, or a Hoosier slick, whatever. But starting to toss weight adders or subtractors based on what tire you chose to run, in order to try and balance the performance ability of one versus the other? No thanks. And if that's not the point of the weight subtractor, to make it a competitive option, than what's the point at all?


I found this to be interesting under "Recommended Items":
GCR
1. #30855 (James Devenport) Request use of tire warmers
Effective 03/01/2022 In GCR 9.3.46., TIRE WARMERS, change as follows:
"Pre-heating of tires prior to competition by electrically heated covers or similar means is prohibited( on the grid)."

They removed the "on the grid" wording, so now not only is it still illegal on the grid *cough2020FPRunoffsracecough*, it's also now illegal in the paddock or anywhere else.

The chassis are entirely different, and per the PAC, warrant different weights.

Racing has never been cheap. Unfortunately, you need to spend money to go fast. It's always been that way. But per Kevin's reply... you don't need to drop coin to have fun. You can run whatever tire you like to save money and still have just as much fun on track as the rest of the group.

How come I could not get a weight break VS the BMW 1600 with my solid axle Toyota? BMW is still l ighter.

Racing cost money for sure . I am aware that SCCA has prided itself on being the best armature racing around.
Face the reality that H Production is one of the cheapest entry level classes that we have . Reducing the running cost per race is a large part of retention. A lousy 2% weight off may entice some racers to buy these tires, race for 4 weekends or more . Win for the regions, win for the racers. What is the downside?? Anything?

The cost per weekend for me is about 2000$ with slicks and 1000 or less on 100TW tires. How many races will I do at 2000 per? How many will I skip to save tires ? Am I the only one ? Doubt it. Just the loudest .
What is the result? 3-5 cars per class per race. That seems to be the number for many of the Majors and most regionals.
Now with the Runoffs qualifying being whatever it is. Racers stay home and pick a couple of races to drive around at. Maybe with cheaper cost per event, more would race more than the bare minimum. Econ 101 says that it is so. Inverse cost participation equation or something like that.

I will pursue a Regional level 100TW weight correction, put cash in for those racers, and try my best to promote HP 100.
The SE division has SM Toyo, SMSE and maybe more classes+ of SM Miata. All aimed to reducing cost and increasing participation. And those classes are flourishing . Simple math . It's not rocket science.
Keep in mind that all of the alternate series race on 200TW tires and kick our ass numerically . The tire cost was a major selling point of those series. We ran the same tires for at least 2 events. 24 - 30 hrs was not out of range .
Finally , I will try to make a couple of Northern races in 22 and try my hardest to beat Jason Stine with my 24HC 100 TW tires . :)

so the 1500 Sprite gets 1.25in Carbs?, I would certainly think that should be allowed on the Spitfire as well.

Come up any time! I’ll even take you out to dinner so you can save $$ and buy more 100 TW skins :D

I think THAT was an oversight. Looks like it was just a copy and paste from the 1275 spec line for carb allowances. Should be the same carb as the Spitfire 1500 and unless I’m mistaken, the 1500 never came stock with an SU carb in the US. It was an aftermarket upgrade and the ZS is standard. Therefore, that spec line should be changed to have the same wording as the spit 1500 and not allow 1.25 SU.

Kevin or Bill T - can you comment? I do not believe this was intended…

Yes, that's wrong. I've already sent in the request to have it corrected. It should be the same as what the Spitfire Prep2 1500 has.
