FROM 2001 SCCA FOURM

some more info, from another thread in the Technical Forum, about Roll Cages...

6. Material:
A. Seamless, or DOM (Drawn Over Mandrel) mild steel tubing
(SAE 1010, 1020, 1025) or equivalent, or alloy steel tubing
(SAE, 4130) shall be used for all roll cage structures. Proof
of use of alloy steel is the responsibility of the entrant.
B. Minimum tubing sizes (all Formula, Sports Racing, GT, and
Production Category automobiles, and all automobiles
registered prior to June 1, 1994) for all required roll cage
elements (All dimensions in inches):
Vehicle Weight Material
Without Driver Mild Steel Alloy Steel
Up to 1500 lbs. 1.375 x .095 1.375 x .080
1500-2500 lbs. 1.50 x .095 1.375 x .095
Over 2500 lbs. 1.50 x .120, 1.50 x .095
1.625 x .120,
or 1.75 x .095
C. Minimum tubing sizes for (all Showroom Stock, Touring and
Improved Touring Category automobiles registered after June
1, 1994) for all required roll cage elements (All dimensions in
inches):
Up to 1500 lbs 1.375 x .095 DOM / Seamless / Alloy
1501-2200 lbs 1.500 x .095 DOM / Seamless / Alloy
or 1.500 x .120 ERW
2201-3000 lbs 1.500 x .120 DOM / Seamless / Alloy
1.625 x .120 DOM / Seamless / Alloy
1.750 x .095 DOM / Seamless / Alloy
or 1.750 x .120 ERW
(American Sedans may construct to these
specifications regardless of weight.)

3001-4000 lbs 1.750 x .120 DOM / Seamless / Alloy - No
ERW
Over 4000 lbs 2.000 x .120 DOM / Seamless / Alloy - No
ERW
Main hoop: 4 bends maximum, totaling 180 degrees ± 10
degrees.
Front hoop: 4 bends maximum or Front downtubes: 2 bends
maximum.
Rear hoop supports: No bends.
If any of the above bend requirements cannot be met, all
components of the roll cage shall be fabricated from the tubing
size(s) listed for the next heavier category of automobiles.
D. For purposes of determining tubing sizes, the vehicle weight
is as raced without fuel and driver. The minus tolerance for
wall thickness should not be less than .010" below the nominal
thickness. Improved Touring roll cage tubing sizes are to be
calculated based on the published vehicle weight minus 180
lbs.
E. An inspection hole at least 3/16 inch diameter shall be drilled
in a non-critical area of all tubes with a specified size to
facilitate verification of wall thickness.

If anything I will probably follow as closely as possible the rules & regs for AIX. I may try to run this car in that class sooner or later, but of course I will be at a major disadvantage in the weight category. Everything else is looking decent and Jake's subframe is an approved subframe (the class requires stock subs or an approved aftermarket bolt in version)

I agree!

A lot going on over here lately. Glad to see you're making progress Dave!

When you do you get your bad mamma jamming engine back in the car ?

:offtopic: does anyone know what the original side markers and front signal lights look like for 68 camaro? where they amber with amber light or white/clear with amber light? I have to buy some and when I get an inspection they may say something if its clear I have to follow DOT standards for now :bang:

Brett is coming up this weekend it looks like (and maybe even my arch nemesis Rob :stirthepot:) to grab all my stuff and take it all down to his new shop and start kickin some ass on it. Can't wait. :thumbsup:

Hey Sean, I actually do not know as I have never really paid attention to that. But I am sure someone on here knows and can chime in for you with an answer.

FRONT SIGNAL ARE AMBER AND FRONT SIDE MARKERS ARE CLEAR


REALLY??? YOU'RE GONA LET ROB BE ALONE WITH BMF???:confused59: :bitchslap: :lostmarbles: :underchair: :gitrdun:

Ok I have been playing with my new MSD 6AL-2 programmable box and trying to set up a fuel curve here. First time doing this and wondering what you guys think.

On the dyno we ended up with 30* timing (dist locked out).

Since I will run this on the street occasionally and thought programming some retard down low would help at start up and low speeds/off-idle.

Figured the idle will be in the 1100-1200 range so I started the curve at 1400 rpm and have it all in at 3000. I've some curves where the retard is linear from zero up to 2500 or 3000, and then I have seen some like this where it's a "flat lined" constant retard for an rpm range before getting up to all in at 2500 or 3000.

What do you guys think?

With that combination, you won't bog it down in gear below 2,000 or so. If you do, you will want less timing to prevent detonation.
