Instructive Video of FV front end at work: http://www.youtube.com/watch?v=dombJDMiOc0 I try to keep my link pins as tight as possible with no binding. Like Brian M. I don't believe the shims are for adjusting camber. They are for adjusting end play to align the top and bottom carrier to spindle conn...

Ray, 3.5 might be enough, but it would be cutting it close. My guess is that it would depend a bit on how rich you run you engine and how well your fuel picks up as you run low. I just looked through my notes from lots of sessions at RA. My per lap usage varies from under .2 gal/lap in a couple race...

Brian, I agree with you on the small radius being an issue. I'm not sure I agree that the material and fabrication is of poor quality. I had one in my hands and actually did some hardness tests on it in various places and compared the numbers to a real VW part. The materials appear very similar, res...

To expand on Jeff's response: From the March 2010 Fastrack: FV Spindle and carrier In 9.1.1.C.3, add a new section: “11. Alternate spindle from cip1.com part number C26-412-020 and alternate spindle carrier C26-412-025 are allowed.” Consider also from the 2010 GCR itself: 9.1.1.C.3.A.7 Standard stee...

Dear Bruce F., I spent 2 hours late last night reading and rereading what you "actually wrote" to try to understand what you were driving at then to respond in a civil, point by point manner. I believe I did so. I'm done with this and cede the last word to others. Please, FV drivers, vote ...

Greg, I wish our manifolds were 1/16" thick. Then there would be no distortion issues. Sadly, after ball sizing and acid etching the stock VW part, it is closer to .020" thick in many cases. The Aussi spec. manifold was 1/16" thick and it felt like you could have driven a truck over i...

Your facts have no bearing on our argument. You are stating that a rule change, from '96 to '97, that was more specific in where to measure was the cause of our current problem. A whole lot of mud slinging is being done on this thread accusing people of lying when the irrefutable facts show they ar...

First the facts... 1996 rules (from my 1996 FCS): Down tube -- 1.140 inches O.D. Horizontal tube -- 0.994 inches O.D. These dimensions shall be an average of at least four (4) measurements at equal intervals around the tube at any point. 1997 rules (from my 1997 FCS, all with black bars in the margi...

The FV committee supports the proposed rule change as it currently reads in the Fastrack. The measurement method and determination of legality needs to be as straight forward and foolproof as possible. The crb did make some changes to our recommendations, but we support the final proposal. It is the...

I think the "no structure, item or component other than bodywork" wording from the FV rules would exclude even an attenuation device that extends more than 10" ahead of the lower beam tube, unless the attenuation device WAS the bodywork. I'm just stating my opinion here and SCCA might...

Doug, you are right about the 15" minimum inside dimension at the attachment of the main hoop to the chassis. As I said, only did a cursory reading of 9.4.5. When I did my frame modification a while ago, I read it all very carefully and Brian H. is right about what defines the chassis: it is no...

As far as I can see, there have been no substantive changes in the frame requirements within the FV rules section since at least 1994. For 2008 we did change the wording of the last line of C.2 from: Body depth at firewall, Minimum: 25" to: Body height at firewall (bottom of frame to top of bod...

Ray, That's correct, it's either one or the other, not both. The reason for showing both is to give some kind of comparison between an averaging method vs. a no-go method. But our average was a 2 measurement average of the max and min OD taken just at the point of the maximum OD in each bend. Again,...

If interested, take a look in the Committee News section for a post with links to the manifold data.

Linked here are an Excel spreadsheet, and images of the individual worksheets from the spreadsheet that contain the manifold data that the committee received from FV drivers and engine builders, manifold makers, etc. A Word document is also linked that explains each measurement. Download the Excel s...

Where and when I grew up (upper Midwest, early 60's) it was called "Bug Slug". There was even a points system. When you saw any VW product (all air-cooled), you yelled out "Bug slug convertible" (or whatever) and socked the kid next to you in the shoulder. You didn't hit your big...

A couple more comments (just to confuse the issue...): 1. Yes, there would really only be "go" limit. That is if the gauge doesn't "go" over the tube the manifold is disallowed. The common term used for this style of QC is go/no-go so that's what we wrote. 2. With or without the ...

For those who want the whole thing, below is the complete current manifold rule. I thought including it within the minutes was "overload". I guess I was wrong. At this point we have made our recommendation to the FSRC and indirectly the CRB. What they accept is TBD. They will do what they ...

"It should be noted (again) that these dimensional limits would be in addition to ALL of the existing limitations currently stated in GCR 9.1.1.C.5.D.20"

Could we be more clear?

Ed is right. When I was taught to do king pins on street VW's, I was told that if they were a bit tight it was OK, even desirable: "They will free up in time". In a FV you are better off with a touch of free play vs having them tight. You don't have any time to "break them in". T...

I agree with all of the above as possibilities. Dan's suggestion is the place to start: determine if tire scrub is part of the problem, which with wide tires, etc. could make low speed steering tough. If you determine that it is the steering box (it's stiff even with the tie rods disconnected), you ...

A car will not lean (roll) into a turn, no matter the CG to roll axis relationship. I believe this is incorrect. In fact my father did his PHD analyzing a suspension design that did exactly this. It made the car handle "like a boat with an outboard motor" which leans "into the turn&q...

pressure inversely proportional to volume Perhaps it has been a long time. John Indeed, too long. Inversely proportional is not linear. Silly me :oops: As you say, the non-linearity would be greater when the volume of the pressurizing gas is small relative to the volume displaced by the shaft in su...

But, air volume displacement "springs" have nonlinear rates. John Maybe if the air is in a flexible bladder, but in a rigid cylinder I don't think so. For a given starting shock pressure P and gas (nitrogen or air) volume V. Assuming the shock fluid is incompressible... PV=nRT... assume t...

Talk about calling a bluff!
