Class designation for production turbocharged Motorcycle?

[donpearsall]

Would a production turbo-ed bike be a P-PB? I also see in the records that there is a P-PS, but the rule book does not list a -PS engine class. What is it?
Thanks

I don't have a Bonnie rulebook handy but in the ECTA world (which is genrally the same for classes) a production supercharged (turbo) motorcycle would run in the P/PS-(whatever cc) class. A non turbo production bike is P/P-(whatever cc) and a production pushrod is P/PP-(whatever cc).

The production classes are a bit different then the modified/altered.

Hope this helps!

Thanks Deb. So the engine class is not PB (for Production Blown)? There is a -B engine class in the rule book, but not a -S. Does S mean supercharged?

For SCTA classes

425 P-P Production Frame Production
426 P-PP Production Frame Production Pushrod
427 P-PB  Production Frame Production Supercharged
488 P-PV  Production Frame Production Vintage
489 P-PPB  Production Frame Production Pushrod Supercharged

The only PS is partial streamlining.

Don, what Deb writes is correct for ECTA(Maxton). Anything before the first break is frame and body related, anything after the first break is engine, power adder and gas or fuel, (and then comes displacement in CC of course).
With this in mind the following and current Maxton 500cc record is a Production/Production Supercharged entry via ECTA.
P/PS Scott Guthrie Racing May-98 113.498 

As Dean explains it(and relative to the area your question is), it's different at SCTA(Bonneville and El Mirage).
With that in mind the following and current Bonneville 500cc record is a Production-Partially Streamlined entry via SCTA. 
P-PS Gary Webb Honda 8/03 127.928

I(like Deb),  can only help in deciphering the ECTA alphabet.

   Well, then. If P-PS is as you say, where is the engine class. I do remember seeing that record before and couldn't figure out what it was. According to the SCTA Rule book I'm looking at PS is Production Supercharged. Same as production but with an original brand factory installed turbo or supercharger. 

So it would seem SCTA and ECTA classes read the same. Whats before the - relates to the frame and what's after relates to the engine.

I see the P-PS record, but if you want to run at Bonneville you need to enter a Body Code from Appendix A (for a motorcycle it is the frame/engine combination) on the entry form, and the ones that I listed are the only ones available. P-PS isn't one of them

Jason on 1 of my bikes holds the P-PPB 500 record at both EM and Bonn.
It was forgotten but not gone also when the wizards invented so many classes.
When he showed up with it and suggested they forgot it, they said he would just have to come back next year if he wanted to set a record.
That didn't set too well with him and some nastygrams got it fixed but only after they tried to blow him off.
It would seem they have forgotten the others in production without pushrods also.
It is tough to do it right when your focus is so scattered.
That level of mentality is a big part of the "Us and Them" that will spell their demise within SCTA if they are not careful.

Both organizations appear to have added and subtracted class seperation designations over the years(and it most likely continue), the objective is to do what you are doing Don and get the proper answer before the question really NEEDS asked and defined(as Jack referenced).

PS and PB as the second designator are commonly defined between venues. And although SCTA recognize both, it appears from Dean' explanation that they only currently authorize the latter, while ECTA only recognizes and authorizes the former.

All BASE ECTA classes were obtained from the SCTA.
Sometimes differences shown can help regain unity. <---(the scrunchy face is correct)
