Yes, as Greg said I mount all transponders in front of the clutch pedal behind the frame rail. Then I drill a hole through the belly pan and cover it with duct tape, Those transponders are way to expensive to mount them in a vulnerable place IMO. On another note something I learned is that if two ca...

Well you won't be surprised to hear that the average age of a SCCA member is 50

Well the stroke could be measured by removing the spark plug and inserting a rod and measuring the distance that the piston travels. Measuring the bore could be a bit more complicated.

Ask and you shall receive. Here is the dyno sheet from a Penske 7600 that I just purchased. This represents the factory standard valving.

Brian, I installed a 14ga steel belly pan in my M5 that weighed 22 lbs. It was welded to the frame rails, virtually impenetrable, way stronger then a .030 riveted aluminum sheet, and the weight was in the best place possible, the bottom of the car. I have been bolting weight on my go kart for years ...

I like the " Mr Harding" it shows respect and solves the double Brian thing. I would suggest that we need to also use " Mr. Macarthy" for Brian "M"

Tire spring rates are available on the manufactures web site last time I looked.

Brian, there is no short answer to that question and I have had a long weekend. Lets talk about that next time we see each other at the track.

Would that not make the wheel rate half of the spring rate in the case of most FV suspensions making the shock pressure even less relevant? Brian Absolutely, but I would use the term less effective, not less relevant. All of the top runners in any class understand that it is the small things that c...

Yes, Brian "M" you are one good looking dude.

BTW, nice to see you at the track yesterday.

Brian "H" IMHO your stiff suspension theory is all wrong.

Using the "100 psi and moved the shock 1", the pressure would be 133 lbs, a difference of 33 lbs and about 6.5 lbs additioanl force on the shaft" as an example, the spring rate would be 6.5 lb/in? How do you combine two spring rates to get one value? Brian Don't forget to factor in t...

Ok, one of the two Brian's need to change their names. It's getting me confused.

Sorry to hi- jack this interesting discussion.

Brian, I have yet to see a FV with high shock movement. Most FV's have a rear motion ratio of less then .4 and the front isn't any better. After re- reading your post I think you mean hi shock travel.

The pressure charge is contained in it's own chamber. At one end of this chamber there is a floating piston that separates the air chamber from the oil chamber. When the shock shaft is forced inward or you might say in compression, the pressure in the air chamber offers a slight resistance to the in...

I have found through my testing that the shock air pressure makes a difference. Not huge but noticeable. I run pressures that are radically different then everyone else and have found it to be a benefit.

Compressed air works fine. I have been using it for a couple seasons and was told it would be fine by my shock guy.

I used to be in the "weight doesn't make that big of a difference camp" until I recently had my son, who is about 25lbs lighter then me, drive my car on the same test day in the same conditions. WOW is all I can say after reviewing the data. I am currently about 200lbs and 6'-1" I wou...

Just as a follow up I did contact the people at Eagle Fuel Cells. I gave them the dimensions of a standard, off the shelf, ATL FC152 cell. They came back with a price of $925.00 So much for a low cost alternative to the other two manufactures. I ordered my FC152 today from SR for $550.00 I'm in the ...

Here is a link to their web site.

Dave,

One additional note: you will want to put the sway bar in the lower tube of the beam, not the upper. I put mine in the upper tube and it caused one of the ball joints to come out of the control arm at about 90mph. it was a wild ride.

Bruce,

With the way that I like the car to handle, and some of the unique suspension settings/designs that I like, yes, it works very well. I wouldn't recommend it for everybody.

P.S. Please don't tell anyone

Indeed it is an anti-sway bar. It attaches to the same point on the leading arm that the shock drive rods attach to.

Everyone told me that it would not work but I had to try it for myself.

Finally finished the rebuild of the M2 late last year. Thought I would share a few pictures.

Your preaching to the choir, that is why I built the Mystique M5 FST. In my mind, FST is FV............. with the addition of logical parts upgrades and logical rule upgrades, like the increase of the minimum weight. I can not make minimum weight in my M2 and I only weigh 200lbs. Over half the FV fi...

I can, drum brake backing plates are not made by any aftermarket manufacture that I know of. I don't believe that new intake manifolds are available either.
