Are SSIs considered headers?

[DaddyGlenn]

After my next SCCA solo event in two weeks, I will move out of the novice class.

Does the fact that my car has SSIs and a camber bar force me out of the BS and into the BSP "Prepared" class?

What effect does a move 964 grind cams have on my class.

BTW, I'm running street tires and have no othermodifications.

[juanbenae]

yes.

[DaddyGlenn]

Thanks Toby.

Not exactly what I wanted to hear. But I kinda figured that would be the case.

Do you know if a 964 regrind on the cams would put me into the "modified" class or would that be considered a legal "update?"

Anyone have recommendation of upgrades/modifications to make my car more competitive in the BSP class?

[LARRY SHARP]

are you sure your car wouldnt be in ASP? a aircooled 911 up to 3.6 liters is there I thought. the cams wouldnt make much difference I think but they may be not allowed.

Cams are an internal engine component. For PCA it would put you in a modified class.. I can't imagine it wouldn't do the same for SCCA events.

[Dave at Pelican Parts]

I believe in SCCA, you would go straight to Mod, or perhaps "only" to Prepared (not Street Prepared). The update/backdate rules apply to complete assemblies only (e.g., all of the engine, or all of the transmission) and not to individual parts.

--DD

[LARRY SHARP]

But the SSI's probally bump you to street prepared since they arent stock to your year car

[Dave at Pelican Parts]

They might not if the car was a 74 or earlier with the early-style exhaust. But a stock-class SC would have the stock roundy-roundy smog exhaust, and the SSIs are very much non-stock for it. So yeah, an SC (or any 74+ 911) would go straight to SP just for having SSIs.

Where would the cam swap put you? One friend who asked that question was told this answer: "You don't have non-stock cams on this car. No, trust me--you don't."

--DD

[DaddyGlenn]

Well... the 964 would be in "B" so why would a cam grind from one "B" car in another "B" car make any difference? Right?

[NathanR]

If you go into Street Prepared, you'll be in "A" Street Prepared, not B. I looked it up a few days ago. Stay in B Stock.

[rfn026]

I doubt if anyone at a local event would give you a hard time about the SSI exhaust and camber bar. You can be certain that at the regional and national level you will be protested. It's going to be a lot easier to remove those two items than it is to build a whole new car for the SP class.

Stock is a good deal for you. Anything else calls for cubic money.

As of 1/1/07 Porsche 911 to 3.2L are in BSP. BTW, if you really want to cry, your Carrera style oil fed chain (I am assuming you have them)tensioners "technically" make your car illegal in BS. As do turbo tie rod ends. (In fact turbo tie rods take you right to Prepared, not legal in BSP, as they were not available on any 69-89 911.)

[LARRY SHARP]

Yeah those turbo tie rods and oil fed chain tensioners sure do make my car faster.. No offense to anyone whos a SCCA person but they sure do put our older Porsches in very non competitive classes. I am glad to see they move the older ones down to BSP. In ASP I would have to run agianst the newer Vettes which are very very good autocross weapons

[DaddyGlenn]

So I'll leave everything as is and and run in the BSP class, keeping my focus on driver improvement and fun.

If I start beating the pants off everyone (risk of protest) or get the urge to compete seriously, I'll find a different weapon.

For now, I'm having a blast!!

[dfink]

As soon as you touch the internals of the engine you go to Prepared in SCCA. I am pretty sure that you would be FP. Porsches are excluded from SM and SM2.

[newms]

I don't mean any disrespect, but this thread is a perfect example of why the internet is a place to gather information carefully. Porsches are excluded from SM, but are absolutley legal in SM2 and in fact SM2 is a great place for lightened, engine swapped, fiberglassed hot rod type 911's to run. There are weight minimums based on displacement etc. but really liberal rules. The problem is the rules are liberal for all cars!

[dfink]

Guess I didn't know the porsche qualified as a 2 seat sports car. I did send an email to the scca technical advisor asking if it qualifies for SM2. I will post if and when I get a response.

[dfink]

OK I guess I will recant the SM2 statement. Though I can't find where SCCA has clarified the statement and they don't appear to want to answer the question I posed to them directly I will have to go off the advice of others. SM2 or FP both allow the engine mods for the cam. Either are tough classes.

[dfink]

OK Just for future official reference I received an email from scca technical advisor D Gill that the porsche 911 is legal for SM2.
