I would suggest we do tech for the GT classes at the same time.

[John Streisguth]

I'll have to remember that...

[Noose]

We may still do them separately due to some people's work schedules.

The regulation of "RetroPro" is same as that of SCRRA?

Haruki

[Matt Bruce]

Haruki raises a good question regarding RetroPro. I would hope under whatever rules we run, that the X12 arms will be allowed. Last I spoke to Jay and Mike they said they were.

Jay will most likely post something real soon so everyone can prepare accordingly.

[Noose]

We at working on an IRRA™ rule set. Nothing final yet but at this time it appears X12 OK, as well as .015" front, .050" rear, and .790" rears.

Stay tuned.

[Rick]

Was that a typo? You mean .790" and .040"?

[Noose]

Nope.

[Noose]

It appears the initial rear clearance will be .040" thus making the rules in line with SCRRA.

Stay tuned for further info.

[Cap Henry]

Myself and Mike Muir are in!

[JerseyJohn]

Awesome, guys!

[NJ SpeedZone]

RetroPro for the Fall Brawl will be using the SCRRA rules: .015" front, .040" rear, and .790" tires.

Thanks,Mike Iles

ILLUSTRATED LIST OF APPROVED RETRO PRO BODIES: CLICK HERE

Please refer to the SCRRA Can Am rules for all specification, except for the following:

RP-1. Chassis construction
RP-1a. Drive type: open to the imagination.
RP-1b. Hinged movements in any direction are allowed.
RP-1c. A single straight, one-piece front axle of a minimum 1/16" diameter is required, carrying both front wheels. NO hinged front wheel movements are allowed (i.e. no "L" arms). Front wheels may rotate independently.
RP-1d. Rear axle: two methods are allowed:
1/ An axle tube of constant diameter capturing the axle bearings. The axle tube may be notched for motor clearance. This axle tube must be held by the steel, bronze or brass-wire main rails.
2/ The bearings are set in a one-piece formed sheet brass bracket that may also hold a bolt-on motor bracket soldered to the base of the main rails.

RP-2 Tires & Clearances
RP-2a. Minimum Rear Tire diameter: 0.790"
RP-2b. Minimum Front Tire width: 0.063". O-ring tires allowed. Minimum Front Tire diameter: 5/8"
RP-2c. Minimum clearance: 0.040” at all points under the chassis rearwards of the center line of the rear axle and 0.015” under the most forward part of the chassis.

RP-3. Body rules
All SCRRA Can Am body rules apply except:
RP-3a. Bodies must be originals or exact reproductions of pre-1974 Can-Am or Sports/GT pro-racing bodies by MAC, Associated, Dynamic etc. or from new molds made in the spirit of the period bodies. Maximum body length: 6-5/8'. Bodies must be mounted following their marked trim lines.

RP-4. Motor rule

-Fitting of screws to hold end bell to can, installation of ball bearings and shunt wires. Magnets MUST remain stock items. Magnets may be shimmed and glued to can. Can may be trimmed at rear side's corner to clear the rear axle. Can's nose may be trimmed to clear chassis rails.

Mike, Jay, John,

There are a couple of clarifications I/W on the SCRRA RP rules that actually will make them a bit more liberal in one area as compared to the current wording. Plus a restriction in one area that is really a wide open chasm of a loop hole. Bryan W. has been working on them and they will be ready soon.

So basically anything that was legal at the CPC and Zimmerman Speed Festival will be legal. They were run under the D3 rules then in effect.

See y'all in the fall.

[Bryan Warmack]

Mike, Jay and Fall Brawl Retro Pro racers,
Seattle racer, Tom Hansen, who will be attending the Fall Brawl called me yesterday and said Speedzone will be using the newly written SCRRA rules for the RP race in November and we discussed several concerns of his about the rules. A recent change to the SCRRA rules which includes RP also and will be officially added in September is regarding chassis construction and the materials allowed. Beginning next month the maximum allowable piano wire rod that can be used will be 1/8" (.125). The SCRRA and D3 before them have never limited main rail cutting or grinding to make rectangular spring steel flat pieces but this just puts a reasonable limit on the size of the piano wire that can be used to make flat rails.

Another issue we discussed was the SCRRA rule concerning body cutting and trim lines. The rule, "Bodies must be mounted following their marked trim lines" was primarily written to control excessive trimming of the FRONT for lowering purposes. (see pic) As Tom pointed out to me, most of the RP bodies don't even have any SIDE trim lines.



After a few races some bodies seem to just naturally droop and a little trimming is necessary to keep from dragging. This would still be a legal body and our body enforcement rules are fairly liberal. I suggest Jay or Mike or anyone in charge just use the SCRRA rules as a basic guideline and decide how strict you want to be at the tech table. Have Fun and I hear some racers from BPR may make the trip!!

[JerseyJohn]

Brian great info thanks. There is allot of excitement in running RP. A, angle-winder B, open x12 arm . Will you be coming east ?

Regards JJ

John,
Unfortunately any faces from BPR this year probably won't include mine!! I hope to make it sometime. The RetroPro cars are great. They even work well on our little 90 foot Kingleman out here and it's kind of like a wingcar race............just brutal nonstop action and speed!!

[JerseyJohn]

Brian what kind of gearing on a king ??? Thanks, JJ

[Bryan Warmack]

Brian what kind of gearing on a king ??? Thanks, JJ

John,
Ask Jay as he was the Retro Pro winner at the Checkpoint Cup!! Everyone seems to be geared around 5:1 at BP. 8:40, 8:39, 8:38...
We are also considering a maximum rear body height...........something probably a little more than 1 5/8". I will let you know in a couple days as we are amending a few rules as of September 2012. ALSO.....spoilers are NOT allowed in Retro Pro.

[Rick]

The fastest retro class avialable and no spoiliers, I am sorry, but that makes zero sense to me! WHY????

[Cap Henry]

Rick, I'll let you run my retro pro car LOL

[Bryan Warmack]

Rick,
As you speak!! we are discussing a maximum rear body height and changes which will include.... SPOILERS!! We hope to have these changes sorted out in the next few days and I will let everyone know!

[Ron Hershman]

In ORS we have allowed a maximum 1/2" rear spoiler to be added to the body.
