HSR-West 3K Class (2.5l) Questions?
 

Hi Guys,
We plan on campaigning our cars to HSR-West next year and was looking for some info on classes for my 2.5L Porsche 911. I see on their site that I would run in their Production Class 3K (2.0L - 2.5L). On their site they do not list specifics to tire size, aero, wheel size for the 3K class (They do for their 2.0L Porsche Challenge- but that is not my class). Anyone have more in depth rules to share? I thought I would check here before calling them. Any info would be great.

The HSR West rules are a bit understated, I guess you could say. Essentially you bring the car that was raced with some other organization such as IMSA, PCA, POC, SCCA, ALMS or whoever and race it as is. If the car was built up for vintage racing specifically then it probably matches someones rules such as the SCCA CP or CP-3 or SCCA GT classes. With reguards to tires, everyone uses the largest that will fit under the fenders and in the case of early 911s or 914s that is usually 225 size. That is why the 225 was picked as the 2L challenge size tire. In the medium bore group or Porsche group at larger events there is a real mix of cars such as the RSR clones that John-James in Phoenix has or the roadster 914s of Jim Patrick or the 80s and 90s PCA/POC GT cars. At smaller events there will be a big mix of Datsun and Alpha 2.5L sedans, Miatas, BMW spec cars and a 944 spec car or two thrown in. So in the end, the answer is really it doesn't matter a whole lot as long as the car and driver are safe and looks and runs good.

Thanks for the info. I have raced against those RSR clones before and it was very fun. One of their tires was the size of two of mine.
Are their any Porsche ST clones out there? I'm getting ready to give my car an overhaul. I have always wanted to convert it to an ST but just hate the idea of cutting the rear fenders off my 69 E. I guess I would keep the narrow fenders if I ever wanted to weld them back on.
Are their any weight limits? Do they weigh cars?

Chad, contact Ron Zitza at Zotz Racing in Orlando (don't have the number handy) He races with HSR in the east and campaigns many different class Porsches out of his shop. I'm sure they run the same rules on both coasts.

Not sure about the rules east vs west. You might also want to contact Frank Beck on this.

So Chad you are jumping ship?

Just you and your pops or the whole Plavan gang?

The only time I have seen any cars weighed was a several years ago at the height of the Porsche 2L series, which has pretty much drifted away now. When Motul was sponsering it and we actually got some $$$$ at the end of the year for winning a class such as 194-4 or 356 or 911 or 914-6 for example there were a couple of 911s that were really fast and they got weighed after being protested by one of the shops concerned. They were both slightly over weight and their speed was due to really fast old guys driving them. One was a retired brain surgeon from the LA area in a silver 911S that was a PCA car and only had a roll bar and fire extinguisher, etc and was really fast. The old guy could barely walk and we used to help him get in and out but once he got strapped in tight he was foot to the floor!

It was very interesting to watch someone with a 914-4, running a slightly tweeked D-Jet FI system outrun a 911 with a 50k engine at the CA speedway because the car was at minimum weight and the old guy driving was an ex IMSA CanAm driver!

Final thought, are you running one of the trick gear boxes with the 904 input shaft and a really high 1st gear so you use all 5 speeds on the track? That is what many of the 911 drivers use on both coasts I think? I could never afford to go that route but wish I could have.

I've helped put one of those 901 gear boxes together for the SCCA runoffs at Road Atlanta for a 914. Man that was 16 years ago already.
