SCCA catagory for my 914-4, racing catagory 914 Options

[FastFroggy]

Hello all,

I previously ran HPDE events and autocrosses prior to my engine issue. I am now wrapping up my 914-4 rebuild and just passed my SCCA Licensing Class. Really enjoy running the car. Would like to see if there is an SCCA class I can fit it, but looks tough. Looking for guidance on the best path forward given my stated priorities:

1. SCCA regional level minimum
2. Extent of further modification needed
3. Relative competitiveness in class

My car:
a. 1973 914-4 with up to date safety items(Cage, extinguisher, seats, harness, etc)
b. 2.0l stock internals
c. race headers
d. large bore twin carbs
e. 5 lug conversion
f. 911 1973 rotors
g. 911s calipers front
h. fiberglass fender flares

Please PM me with feedback. Thanks, GregM

Thanks for all the insight. Really appreciate it.

- Have an SCCA Race Novice Permit.
- PM'd Chris about a fuel cell
- Stamp on cage is 50-07009
- Looking at the cage, I will need to verify about the upper diagonal. Probably to add with the lower.
- yep. 7x15s, M Calipers and 40mm webers on the list
- photos to follow in next day or so. reestablishing my drop box/photobucket accounts

Question: PCR indicates only rotor diameter with no mention of solid or vented. are vented rotos ok as long as they meet the diameter? or is of a weight penalty?

Do you have your schools signed off yet? What's the plan?

- Stamp on cage is 50-07009

That was issued by Region 50, Utah Region. Their web site is sparse, but you can send them a note to utahscca@outlook.com and see if anyone can identify that logbook number. If they can, we could possibly re-issue it with that old number.

However, except for posterity's sake, there's not a lot of usefulness versus getting the car re-inspected and issued a new logbook. It would be cool info to have but is not required.

Question: PCR indicates only rotor diameter...

I think you mean GCR (SCCA or do you mean Porsche Club)? With SCCA, you can run one of two brake configs in EP:

- "Front “M” calipers permitted, 914-6 calipers & discs allowed" (whatever size and config they are) with no weight penalty; or
- Any 4-piston caliper and any rotor that fits within the allowed 15x7 wheel, with a 2% weight adder (GCR 9.1.5.E.7)
