Looking at CPS, which is "Classic Production Supercharged", can this be a factory car that came with a turbocharger rather than a supercharger? There doesn't appear to be another blown class for classic production turbocharged cars.
Any idea when the new records will be posted on the SCTA website?
Thanks,
Gentry

Per section 4.FF, a turbocharger is a supercharger.

The UN_OFFICIAL records are posted on the SCTA web site. We are in the process of making any corrections
and verifying them at this time so the record certs and dash plaques and proper information is on the trophy's.
It takes a little time as this is also volunteer time away from our regular lives. with over 2200 runs and record runs to sort out it takes time to assure accuracy. I have just finished the 1st go around and have sent them to J.D.Tone and the SCTA records group.

I had a similar question. Does the production supercharged car have to run the same supercharger as originally equipped or can you upgrade to a super-duper-mammer-jammer supercharger and still qualify in the class?

Does the word "production" ring a bell?

I do not know of ANY productiion turbocharger vehicle running PS or CPS with a stock sized turbo. Good Luck

It is required with bikes, and not so with cars.
The visual rule as presented to run is the difference. :wink:

If we can run a turbo in the CPS class we can stretch the rec big time. We were running 213 record breaking belts. If were allowed a turbo the record would be in big trouble. Let me know cause I'll be your newest challenger for the class. I have built the last 2 cars to set the CPS car records 2006 and 2007. I will shoot for 2008 with a turbo!

You can run a bigger turbo if you wish.
The C/CPS record is 222.226 set at World of Speed by new 2 club member Mark Miller. Look for this car to be faster next year when Josie takes the seat, she weighs 1/2 the pounds of mark. See Danica Patrick controversy from earlier this year.

I thought more weight at bville was better?

Dan did the car have to come with a turbo in the turbo in the first place??
Josie might run slower if she is too light and the car spins the tires (http://www.cybergifs.com/faces/bigthink.gif),

"More or less weight is less important than the right weight in the right spot., even girls know that." (me) :wink:

Yes, maybe.
A blower is a blower. I think if the car came with a turbo it would have to use a turbo in a Production class. If it came with a roots or screw type it would have to run that style in a Production class. It is production after all. Removing a 6PSI Eaton from a 5L Ford and replacing it with a giant turbo just isn't in the spirit of the class now is it?

Yep, I totally agree. I was asking since Steve's post seemed to suggest that maybe they were going to run a turbo when maybe the car didn't have one to begin with and I hated for them to find out in August.

Now I know Ford had turbo 4 cyl., but was not aware of a V-8 coming with one and I think that is what he would run. He talks about breaking belts and I would assume that those were blower belts. Steve what do you have in mind??

Doesn't a 2003 Mustang Cobra run a 5.?L with an Eaton blower? They have drive belts.

Yep, what I was talking about when he said belts and why I was concerned if he felt he could switch legally to a turbo,

No turbo's allowed in the C/PS class, just factory type supercharger that came eqiped on the vehicle. We had to make it a 306ci to qualify for the class. we had to do some things to turn the 4.6 into a 306.

Lets make sure we are all talking about the same thing here. the original poster was talking about "Classic Production Supercharged" and somewhere in the thread it got changed to C/PS which is C engine, Production Supercharged (C/PS). There were very few classic production supercharged vehicles ever available.
Production Supercharged does allow turbochargers if the production vehicle being entered originally came with a turbocharger. Like J.D. said, it has to be like for like but it can be much bigger. You CANT replace a screw type S/C with a turbo and call it production supercharged but you CAN replace a T25 turbo with a GT60 and remain in production supercharged.
On production vehicles the general rule is that it has to appear aerodynamically and visually stock (externally) and since the turbo is external on a M/C you pretty much have to keep the stock unit where on a car it's under the hood and not external so you can change it. At least thats how I always understood it.

Production Supercharged---Heavy Print '08 rule book:
Speceficaly address types as "TURBOCHARGER or BELTDRIVEN SUPERCHARGER" doesn't mention what type of belt.. MUST stay with type and number of either as came originally.
