Vito just pointed out to me that the 944 Spec racing rules include some 928s, and the PCA is adopting these rules, so this may be a new opportunity for 928s to race....

944 Spec Rules in PCA Club Racing

Interesting that they excluded anything after 928S ... but that leaves a HUGE field of performance ... nice.

Thats was a very confusing read. And I read insurance contacts for a living.

928s allowed in SP3, okay - is this a long or a short track? A "928S" is any 928 up to and including the 86.5 cars. So they are saying the SP3 will allow a 928 on the track in t his class? And the motor limitations look like you could prepare a 1978 stripped 928, with a 5.0L 32V S3 engine being run my stock computers, on DOT tires? I can't decipher the allowed sizes.

BC

A 1978 chassis, with a 928S 300hp (or more) "stock" 32V motor, S3 cams, and a 78 transmission with a 2.75 rear end, weighing 3100 pounds at least? Jesus, that would be a track beast right? Even if it has to compete with 2200lb 924Ss?

Rumor has it, that there will be 2 new classes in SCCA that should fit the 928, and replace ITE class. I spoke to one of the directors this past weekend at Laguna, and was given a heads up...

HTH,

Those are basicly the same as 944Cup SuperCup rules. 32V cars are not allowed. By 928S they mean 83-84 US 4.7L. Euros are not allowed in SuperCup if they are different than the US model (78-79 are okay, 80+ not allowed). The 100lb penatly for Euros is interesting in SP3. I wonder if my exhaust would bump me to prepared. If not, I could run at 3300lb and probably be pretty competitive.

BC

Matt are you sure about the 32V rules? It says 928S of any year.

Is there somebody that can get this clarified?

FlyingDog

It says 928S of any year in Stock H. I don't think 32V fit in Stock H. I think they're in a higher class. That was the case with my Euro for SuperCup. Their rules said Euros would be bumped up a class. Since H was the only legal class for 928s my car would be bumped out. I checked this several months ago and I think the rules were 2005, so they could've changed the rules for 2006.

BC

This is where I don't get it. Is there a "larger" rule book that we don't see? More specific stuff like allowable cams?

So you could put a 5.0L bottom end on a 2V Euro head with S2 cams, LH computer from the Euro car running it, maybe even the LH from the USA cars, with chips. ?

FlyingDog

Yup. Stock rules start on page 8. Classes for cars starts on 14. http://www.pca.org/clubrace/docs/pca_rules_2006.pdf
85-86 288hp 928s are in F-class.

E 87-91 928S4 3505 316 11.09
E 90-91 928GT 3505 326 10.75
E 92-94 928GTS 3593 345 10.41
F 85-86 928S (5-speed) 3351 288 11.64
F 85-86 928S (Automatic) 3439 288 11.94
H 78-79 928 3373 219 15.40
H 80-82 928 3439 220 15.63
H 83-84 928S 3439 234 14.70

BC

Okay then Matt. Right you are.

So what is the difference with thsi year that stan was trying to show us?

So I can take a 4.7L (Side note - how would they know it wasn't a 5.0L?) Euro motor and put it in a 78 USA body and the 2.74 rear end.

Sounds like a good one? 3100 pounds, somewhat competitive.

BC

What the hell do I know I've never even been on a track, but I am looking at my options to try and do it.

Stan.Shaw@Excell.Net

Brendan,

As far as I know these are based on stock classifications, so the engine must have come in that year. These aren't classes where you build your car from all the best parts you can find. Same goes with the brakes, transmission and differential. At least that is how PCA club racing normally works, not sure how the 944 spec classes will be integrated, but I can certainly get answers to specific questions.

BC

So they actually have classed the early 928s with between 220 and ~260hp and it must weigh 3100 pounds and stop with (almost) the same brakes as 944s and 924S cars that weigh 2300lbs? That is a 800lb difference and what power difference. Am I being ignorant here? Why the hell are they making these 928s come in at such a high weight and without the later-928S brake upgrade?

The 951 came with the four piston brakes. Jesus. So in SP3, there could be a gutted 3100lb 270hp 928 on the S-brakes and pads and rotors against....No Wait I'm wrong, Stock F is the 951, which Matt says DOES allow the 32V 5L engine on the 928.

In Stock F would they allow the 86.5 brakes?

Jim bailey - 928 International

Correct update back date rule says if it has S-4 brakes then it IS an S-4 and higher class, increased displacement higher class, cam change higher class, underweight higher class ... do just a "few" performance upgrades and the class you run in is against Mark Anderson and Joe Fan ...
