Can I use 914-6 5 lug hubs, wheels rotors, etc?
What are the differences in the 914-6 Caliper and the M- Calipers?
Can I leave the engine lid out and build a tray for the carbs?
What about Scoops mounted in the rear window?
Can I leave out body plugs to feed air to the oil coolers?
Can holes be cut behind the Fog light mounts to feed brake ducts or oil coolers?
Do I have to use the Ginther style windscreen?
Can I use multiple tubing sizes in the cage as long as I follow the GCR for the main hoops and side bars?
Can I go to full Glass fenders and Quarters?
How do you guys do the doors? Can you still open them or weld them shut, etc?
Does air have to be fed through the dryer duct for the engine cooling or can I pull air from the open cockpit area?
Can I put a fairing over the passenger side?
914/6 Front calipers are in fact M calipers.
the rears are like the /4's with bigger pistons
Any reason I can't run Stock 914 Front on the rear?
Check the rule book for the group / groups you plan to run with.
What is OK for SCCA and PCA might not be legal in HSR or POC.
SCCA E-Production.
I am reading a 2001 and 2002 rules set. I don't want to buy and start building to a 2004 rules set if they are going to dramatically change things in 2005 and since SCCA won't publish the rules until Jan or Feb I don't want to wait. Is that cheap or what?
Why no air scoops? I see nothing in the rules about it. it says airboxes are free. I don't think you would have to make any non original openings if you mounted them directly to the engine lid. What about a small flap that would direct air down onto the engine lid, kinda like what Jon Rogers did on his roof top but mine would be mounted in the bottom of the rear window.
"Air cleaners, velocity stacks, and air supply ducts and boxes are unrestricted provided no modfication of the body or chassis is required to accomodate their use."
To me that means as long as I don't have to make any modifications to use them I can bolt them to the engine lid and not have any problems.
Chris is spot-on with his guidance. He knows the rules well.
I see your reasoning regarding the air scoop, but I think if you pushed it, we'd end up having to run that damn rain tray. There are no provisions to "add" anything to catch air. The only legal air ducting is the removal of front lighting equipment in the "Lights and Lenses" section.
The big changes in the production rules are centered around illegal cages. If you build a closed car, build it legal and you're all set. If you build an open car, make sure you build a full-width main hoop that's legal otherwise and again you're all set. If you want an open car with a partial width main hoop, you may be in for a bumpy ride regarding the rules.
I am going to an open car, planned on running a full width cage with a low fron hoop.
Can I make a GT engine lid or do I have to keep the stock grill? would that be considered a non stock opening?
I guess I'm not familiar with the GT engine lid.
The rules say "the hood, hatchback and deck lid may be replaced with components of an alternate material." So, I'd say you have to stick with the stock engine lid, but I guess one could debate that the engine lid is a deck lid, but I don't think that's the intent of this rule.
Word of warning on the low front hoop, full width main hoop.... Unless you're really short, plan on using some kind of layback seat, not a FIA approved seat. I bought a beautiful FIA-approved seat, but couldn't get it low enough to keep the main hoop anyway near the targa bar. So, I had to go with a Kirkey layback seat and I laid it back much further than the 20 degrees that's build in. I had to cut the wings off of it so I could steer. Now, there's not enough side bolstering and I'm bracing myself with the steering wheel. I'll fix it, but I just wanted to warn you on that.
I thought that the Ginther-style windscreens were illegal now. If the short screen was grandfathered-in (i.e. built befroe the rule change), it was legal. All new to the class 914s had to be built with the stock roof.
Later,
Don
No all 914s can run topless. There are no new cars allowed to go topless.
Chris according to my rules:
Chris what in your opinion determines the line between an mechanical advantage and driver skill? Would a car that was built to the maximum designed potential be an advantage?
As soon as my registration comes back I want to ask this question to the production forum as well.
9. Body/Structure
a. 1. "Lightening: Component parts of the car's body/structure, e.g. hood, doors, Hatchback, and deck lid, may be lightened, provided that structural rigidity is appropriate and that the original appearance is maintained save for those alterations permitted by these rules. No non-original openings shall be created. Chemical removal of metal ("acid dipping") is prohibited."
This is enough for me to say the GT lid is not allowed.
a. 15. "Heater plenums that do not serve as a major part of the structure of the firewall may be removed or modified. Any other firewall modifications are prohibited unless specifically approved and listed on the specification line for the vehicle."
That says to me that creating a hole in the firewall for an engine cooling air pipe is illegal.
b. "Integrity of Structure: All permitted alterations, modifications, components, or safety structure installations are understood to be additions to the basic vehicle. No part of the body/frame or unibody shall be altered or substituted unless specifically authorized by these rules or by the vehicle's specification line."
This closes the door to lots of things people would like to do.
Also, you can't use what is allowed in one rule to override something that is specifically outlawed in another rule.
Sounds like there is as much ambiguity in the production rules as there is in GT. Time for a re-write to clarify many of the contradictions. So who wins in a protest, if one rule says you can and one sorta says you can't.
Chris you gonna be around tonight? I'd like to call you and talk some about this. Email me your number.
Good luck at MO. I'll wait until you get back as you will have enough distractions there.
You make a me feel a little better about things after reading the rules all day today and talking with my regional tech inspector.
