Porsche 928 officially eligible for SCCA National competition in GT2 class
I have been working on this for a few years now, and it seems we have finally made some progress. the 928 has been recommended to be added to the SCCA GT2 class for national competition. this means, the 928 can run in the SCCA Run Offs which is their National championships and is televised.
I just got the word this morning.
I think that is a bit of good news for the old classic , Porsche 928! anyone wanting to race "officially" soon will be able to with their Porsche 928. (edit): Officially racing as a Manufacturer model, and within SCCA National club racing)

This is just SCCA taking 8yrs to do something others have already done.
This is not true in any way shape of form regarding SCCA classed racing. Within SCCA, the 928 was never officially eligible for competition, except for world challenge competition for a limited time period (over 10 years ago)
Now, if you are talking about "officially " running in other organizations, that is not the subject matter here. I'm referring to this national class for GT2 (not regional, like ITE) It's important, because now anyone with a 928 can run in the national events , regional events and the televised national championships.
as a reference, the 928 can run "officially" in NASA GTS, or ST2 because it is based solely on production based classing using hp/weight ratios.
That's excellent! I am not familiar with that class.....what kind of mods are allowed. Basically, will the Devore car be allowed?
The problem with custom race cars, is they are not built to a rulebook, so yes, you can race it, but usually in weight/HP type classes, and the 928 is not really the winner car in those groups, too heavy.
Doesnt mean its not fun, just its not a car to win unlimited classes.
One could review NASA GTS rules to see what class a 928 would fit in, but depending on work its a difficult tradeoff if HP and Weight decisions all over the map.
There's ST and PT, but those are classes based on modifications and points-per-mod that put you in higher divisions..and then also a weight problem.

basically its allowed to run in GT2 class because of its history running Speedworld Challenge. it can run in the form Mark anderson ran (i was far below that specification)
basically, cam, intake , headers, wheels , tires, wing, splitter, and then all the basic (ST) safety specifications found in the SCCA racing rule book.

Its not really about the weight of the car, its just an old design that doesnt perform to modern standards. there are corvettes that run faster than anderson ran at laguna seca now, at 320rwhp and 3000lbs on DOT tires! (ST3 class) it is a cumbersome platform that is not easy to run fast. in NASA GTS class, (bmw hybrid e30s with e36 euro motors) your point then reigns true, about weight. the GTS3 cars are running faster than anderson ran and doing so on DOTs as well. all while running near 10:1 HP/weight. (1:40 sears, 1:30 laguna seca) crazy fast!!!! 2500lbs empty weight and all sorts of bolt on and width mods (like 1+foot wider) Generally, for the 928, it can run ST2 (8:1) or ST3 (10:1hp/weight) or GTS 3 or 4.
There are not a lot of racers in these groups and the 928 is not competitive on a national level. GT2 is near the same thing, but it is a little better for the 928 as the car have to follow their stock form factor much more. This is a KEY difference. On a national level, the 928 competes better there. it's televised, its a huge national program.

Just spoke to the SCCA National folks. Looks like the 928 is official on January 1st 2018 for GT2 competition. It will be interesting to see what is on the VTS. (vehicle technical specification)
Interesting news I'm trying to class my cars right now, I think Casper can run GT3 and the new Widow will be GT2 with 360-370 RWHP. Casper has 275
yes, it is GREAT news in my opionion. the 928 finally has an official spot in the national classes of SCCA. this means anyone now can run the runnoffs from this point further and the VTS is going to have further changes to help it with its performance and parity.
HOWEVER, this is not a HP/weight class at all, (like NASA ST2 ST3, GTS4-5) or even an engine size class like PCA. it's a manufacture and model class, which is actually better for the 928s vs the heavily modified BMWs and Vets with serous body work and handling advantages due to major chassis mods.
Casper , can run GT2 in SCCA national. GT3 is a class for small engines. same with GT3 in PCA. under 3.6 liter. what casper can run with its 275rwhp, is ST3 in NASA. but , in ST3, there is some huge competition with the very light BMWs with the same HP as casper. their weights are 2750 with driver. thats very tough in a 928. the lightest anderson ever got was 2850 with driver if i remember. that chassis would be a decent competior due to all the suspension geometry and width changes. but still no match in ST3 with the bmws and corvettes. theyre running near the same times as he ran with 150 less hp on DOTs.
Yeah the 928 doesn't really class well with all the competition It was never designed to be a light weight race car.
welll, it depends. as i mentioned, in NASA GTS2 and GTS3, its only hp/weight but german cars. your going to have a hard time being 10:1 hp /weight and compete with such a MUCH higher weight than the competition. in ST2-3 , its also HP-weight, but the more common competitors are the Vet, and they are in the same weight class, but handle so well due to better balance weight distribution, as well as all the racing bolt on and aero that we dont even come close to having access to. Same thing goes for PCA.... you go against the largest NA 911s with no control of body panels or aero aids, as well as weight.
So, in the end, it comes down to GT2 with SCCA. its a class where the car has to be the weight it had in World Challenge GT and the body has to fit the stockish form factor. limits on wings, splitters, undercarriage aero, etc. For national recognized competition.
However, have fun in ITE, or the other local classes, as there are lots of places to race the 928.
I think the lightest off track weight I got from casper was around 2830lbs.....with my 200lb self and almost warning light on fuel.... I did just see a pic of 2861 with a shade over 1/2 tank

yep, thats what we see too with scots car, and Andersons was in the 2800 range too, but he did all that chassis lightening as well and it was the S4 which has more "stuff".
the main thing is that the 928 vs the M3 or Vet has so many disadvantages the driver is the only thing that can really make up many of them. balance, weight, geometry is just naturally so much better with a car 10 to 15 years newer, as well as the 1000s of dollars they spend on stiffening, geometry improvements, and width modifications along with aero. again, just two guys here locally , one in a vet, ( robs old C5 wcgt chassis) and one in a BMW(TCdesign e36 with S54 motor), both run St3 or ST2 and run 1:52s at Thunderhhill or an amazing 1:31 to 1:32 at Laguna seca on DOTs. these are the very top cars, so the 928 does fit well in those classes against the majority of the competitors in ST2. in ST3, it just doesnt handle well enough to hang at 300rwhp and 3000lbs, vs the 2700lbs BMWs. now, if you make a frankenstein out of the 928 with widening the track, huge 335s on all 4 corners and bolt on a nice set of motos or JRZs with major aero mods.... you might be able to make it work and hang in ST3
go price out a C5 WCGT chassis build or a TCdesign BMW build from Tony. if you spent that kind of money , using the best of everything, we might have a car that could hang.
It's official. the Porsche 928 is officially sanctioned to run in GT2 class with SCCA in their national competition . this means its officially eligible
to run in US Majors tour events and all SCCA regional events, and if you want, as i will be doing, competition on their national stage , the SCCA Runoffs, which are their national championships. (televised too)
Thank for all that helped me with the effort to get the 928 in the books.
