Good day everyone.
Is there any documentation floating around out there describing specs and configuration for 1973 914-4 race cars (SCCA or others)?
If anyone can direct me, I will be gratefully appreciative.
John

The class rules would depend on which organization you would want to set the car up to match. There were/are quite a few such as POC, PCA, IMSA GTU, SCCA production, SCCA GT not to mention the overseas race groups. The best way I would think would be to pick a car that is still around and then make yours match. If you want modern race organizations such as NASA, OTR or SCCA, they all have on line references for things such as safety, allowed mods, etc. As for what to race, the vintage organizations seem to be more laid back and are definately easier to run with with beatin an banging.

You know as a resource it would be nice to have general outline of SCCA allowed mods and setup for 914-4 FP car since this seems to be the most popular class for 914-4's.

There was an article in Panorama (Porsche Club of America newsletter) in the early/mid 70's giving some details about a 914/4 that was run by either Ginther or Garretson in SCCA E prod (or whichever class the 914/4 fell into at that time). The original article might be hard to find now, but PCA used to regularly create books out of assorted technical articles called Upfixin der Porsche. I am pretty sure the article made it into one of those. Good luck!

There are several great racing shops in the PA area, one even has a green 914 GT that has a lot of provenance. I would suggest a visit to them to see how they "interpret" the SCCA rules as they are very complicated to figure out. I think the rules have "evolved" a little bit over the years since 1973/74 for racing in the SCCA FP class. You could contact the SCCA directly to see if the have achived copies of their mod regs but when I looked at this in 1998 I was told that the safety would have to meet the specs of 1998. With vintage class cars it is different as I see many of them racing with 1960s or 70s safety equipement except for the new belts and usually a fuel cell bladder added inside a stock tank. Many cars of that era did not have on-board fire systems and still do not today. Good luck with your quest.

I have that article. I will scan it and post it later.

Here it is.

Holy crap! Cool article. Thanks for posting it!

But.. I think he wanted to know where to put his 73 914 in SCCA.. not 1973 race prep

I could be wrong!!!

His 73 stockish 2.0 fits in ITA with narrow body and stock injection. Car has to be caged, but cage cannot pass through any bulkheads and must have a min of .095 DOM for main hoop.

Stock brakes (any pads) and any cooling.

No rear decklid wing..

There is a lot more for ITA, but it is pretty simple to get the car to SCCA trim.

The rest of the classes for 914's are as follows: EP/FP/GT3/GT2 just add money as you move up the ladder for classes. No 914 tub car will be competitive in GT2 or GT3.

Do not forget that the 914 is in GTL now.

Oh well. I guess I misread the post. I thought he was interested in campaigning a 914 in period-correct vintage style ... still glad the article got posted.

Scott

I forgot about this article. Thanks for posting it.

as for a 1973 914-4, you can race it in FP, but that would cost alot of cash. TI could be configured as a EP car from that era, I will try to get a copy of the 1973 SCCA GCR for you, someone may have it.

Brad you can also run a 914 in GP HP.

I think the question may be more directed at vintage racing and what was period for this time. I have been helping another guy with a car that was raced in the seventies, and have contacted Ed Givler (Edge 2) for his input. Back in those days SCCA separated the "book" into GCR (General Competition Rules), PCS (Production Car Specification), and others. Ed has a 1975 PCS which should give you some solid insight as to what was available at least in 1975. I will scan in and post in a couple days.

Thinking back now, the article Blake posted will be pretty close. For 1973, you only had two choices in motors 1.7 or 2.0. I am not sure what they allowed.

Most of the cars were allowed 15x7 inch wheels, roof cut off, a front spoiler that had to attach at the bumper. stock track plus 3 inches (for the wheels), etc... Some of the other mods are in the article.

I'll try to post in the next few days.

Blake,

without going into great detail, tell me how the 914 fits in GTL/GP/HP ??? This is VERY good info!!




B

You can run GTL with a 1.7 or 1.8 with a 25mm SIR at 1920#. This is what I am building at this time. Full tube frame, Hewland, RAT/HAM engine. GP is being split up between FP and HP. 914 1.8 is a Limited Prep GP car at 2000#. They might be moved it to HP at 2165#. This is not a done deal yet. GP is still a National class they just can't go to the Runoffs next year. In GP the car must have stock suspension pick up points and brakes, 10.5 CR with 420 max lift. Stock FI throttle body and plenum but an ECU and IT head prep.

Thanks Blake!

I have full access to a full tube chassis 914 roller right now. It was setup for a 6cyl, but can run a 4 also.. All Chrome Moly, 5inch round rear control arms.. all heim joint.. custom front control arms..

Interesting thought!

Click to view attachmentirst, I would like to Thank my good friend Ed Givler for providing this information. For those of you that don't know, Ed has been racing since the sixties, and has been wrenching on type 4 engines since the early seventies. Ed isn't as fast as he once was (sorry Ed), but as a well seasoned gentleman, he is still a very solid race driver. I hope I am going as good as he is when I get there.

What Ed has provided me is the 1975 Production car Spec book, and the 1975 General Competition rules (GCR). I have scanned these in for everyone to see how it used to be done.......... Back in the DAY.!

This should answer the questions on what can be done for a vintage car and what can't. The only issue with a 1973 car would be early bumpers, and in EP the engine would only be a 1.7 with corresponding valve sizes. The 2.0 could be run in DP, and the same car that won the Runoffs in FP in 2005 driven by Mark Hotchkiss, was the same car that David Finch drove in DP races back in the seventies.

Here is what I found:

Does anyone know this John guy from Penn?? I'd like to know which direction he is headed..

Is it true you have a new track coming to Penn?


B

Unfortunately, the scanned ones are all over 2mb. Can anyone help me reduce the size, I am not quite sure how??

Erik

Erik, how many pages?

Just like the other one, they are two small 3x5 pages each, I may have to scan them in seperately.

Erik

Brad,

I never really followed-up on this posting. Since I asked the original question, I've learned an awful lot...much form the folks here @ 914Club. My direction, from the start, has been vintage with HSR/SVRA and the VRG Club. Today, I have components and advice from Tangerine, Aircooled and several other 914 vintage guys as well. Parts for the "new" 914 (Blue with and orange stripe #31) came from Chris, Jake and a new engine build at Proformance out your way. In fact, Classic Motorsports Magazine spotted me at Savannah early last year and published an article (June issue, I think) just before the endurance race. What a hoot it was being as the lowest powered car by MANY ponies! I think a Rothmans 956 lapped me 3 times. However, we did a modified LeMans start, and I started the race in about position 6 out of 60 or so starters!!! I was on the track with everytinng from Indy Lights cars, Lotus 23's various sports racers, the Rothmans car as well as a beautiful 906 and many Corvettes and Mustangs.

As a reference point, the orange car was purchased from CA (Mike A.) who I met via 914Club. It was sold to a guy in NC for some DE events to finance the blue car. It was a well-sorted race car that should have been sold here on 914Club, but wasn't. The price was perfect for an entry-level person. Anyway, I get to do about 6 or 7 events each year including the Pittsburgh Vintage Grand Prix...a REAL vintage event. And, my home track is BeaveRun about 30 miles West of Pittsburgh. I don't know of any "new" track coming our way, but perhaps the info travels from West to East.

So, thanks to all of you that pitched in with advice, comments and criticism along the way. It has been and will continue to be big fun for me.

John

Yeah it reminds me of a certain Ford that is posted on this forum. Just WAY nicer!

Thanks Dan...a better driver would improve things, but I try to holdmy own.

Thanks for the kind comment...although I've never seen that "certain ford."

ah-ha. very curious.

Gulf decided to reduce my sponsorship, so I removed the BIG gulf decal from the front of the car.

could tell yo another styory as well...

Thanks for posting the photo for me,

John
