Right front compression

[hucktyson]

How much right front compression @ 1,3,6,9" are people typically running on the right front on big fast race tracks like eldora or Pittsburgh ?

[save the racers]

Never been to those 2 tracks.Don't have my sheets in front of me but I'M at 100 to75 lbs between 3 to 6 with a digressive piston.

[hucktyson]

100# at 3@ and 75@ 6 isn't digressive it's regressive ...

[hucktyson]

And as a follow up question how about at tazewell when it's hammer
Down ?

Whatever it takes to keep it outta the race track. You can't go off compression alone. We didn't change anything on the Shock when we went to Eldora we just didn't get low on the RF spring stayed around a 350.

[Brian Gray]

Tazewell and bulls gap typical shocks have very high compression numbers. Near 700 lb of clamp compression on linear Pistons up in the 1000s mid rate.

I have never built an eldora shock with those kids of rates on compression though. Everyone i do shocks for are very average on the compression at eldora. with exception of 1.

there you go teasing us again, if your not gone tell who and what the " 1 " is, don't even mention it....

[hucktyson]

When you say " clamp " I assume you mean zero point ... Do you run a steel body at that point ? Even at 5 or 600lbs of zero point I feel significant expansion of the body on the dyno ....

[Brian Gray]

Yes when I say clamp I'm talking about the starting point or zero.

And yes we have had some failures. Mostly with alum pistons. No body issues yet.

[Brian Gray]

The 1 Ford i s me . only because of the steel block.

[hucktyson]

I wasn't suggesting the body would fail. I built a shock that made 2200 zero point and 4975 @5" per second based on advice of a soo called specialist . And there was any failures but it seems that when you can feel the body expand as the piston passes that a steel body would be much more consistent in such a build

[Brian Gray]

As long as you are taking that variable into the equation when managing the flow rates I don't see any problems.

But yes the steel shocks I do are much more consistent over the temp range than the alum tube. Significantly more stable, It's goes the same for fixed valve vs adj shocks. I believe afco is coming out with a stainless tube insert for the new body that will help some with deflection. I'm still waiting for an official word if this is happening.

[Brian Gray]

If your having issue with the bulge run some porting into the band on the side (comp/rebound ) where you are seeing the loss. I start With a #7 and drill from center of the band into the port. This will help push the band against the body when the pressure gets extreme.

Usually takes most of the variation out.

[TALON75]

The only way I see any of the numbers you two are throwing around working, you would have to move the decimal point to the left.

[Brian Gray]

When you give away the secrets someone will have to chime in and say your full of it. Believe what you want but I'll lay some cash down that says the club car you guys will have at eldora has more than 70. Lbs of comp . In those fronts

You want to take that bet?
