Yeah I’ve heard that also but I can’t seem to sand enough to get to a 10.8Anytime you take the spring to coil bind, youre going to lose some tension. I dont know of anyone who does that. Ive been told they sand the spring.
They’re yellow stripes I believe they’r3 a little over 11 lbs at 850. I had a guy that was doing it for me and he passed awayWhat #'s are you getting at .850 .
What about pre run springs how much would they lose ?
I don't think sanding is the correct term .
More like sanding on a powered disc sander .
Like this . Lay the spring on the table square .
Preferably with an internal guide . Press against the disc with a # scale and guide set at . 850 . Sand till it reads 10.8.
I have the spring tester and an intercomp tester as well. I will check out the box stock projectthe real way is to get the tech tool. too bad it's $395+ shipping you can get the yellow stripe springs pre set from Box stock project.
Theres been many builders in my shop, and ive known many others throughout my years with the Tri State and other big events and am friends with some of the best in the business and they all said sanding the spring, may not be the correct term but they all said it. Im not sure if there is any actual other term for it.I don't think sanding is the correct term .

Yeah I just have to be 10.8 at 850 install. Problem I been having is having to sand to much getting the lower and upper to thin. Maybe I can sand them then leave the tech weight on them for a bit and keep checking, or run them a few heat cycles to see if they drop.I use a bench grinder. Using the side of the stone. Problem is with todays springs once you get the 10.8 correct the 18 lb is off or viser versis
Are track has talked about drop in red springs. But the issue some members have is the other tracks they run don’t follow suit, so they complain about pulling springs. Are clone class runs 212 motors flat top pistons .040 longer billet rods and a Mod 2 cam, combustion chambers open no porting but can mill the heads. Springs I had before Covid hit I ran for 3 seasons no joke no issues, now I’m lucky to get 6 races out of them.IMO the springs are an issue and have cost many a racer. we have tried on the dyno several types of springs including illegal 10.8 with no HP advantage. we should just go to height, diameter of wire, and number of coils and be done with it.
