Not for Nuthin' But Close!

Aren't welded spider gears illegal? I wouldn't want to be on either end of that law suit. (The one that could ensue when an accident occurs because a weld or gear broke.)

Yup. Under General Regulations 2:11 Rear End,Welded spider gear rear ends prohibited in all classes.

They do it a lot in the fwd Dirt cars, never ever hear of anybody breaking one. Seen a bunch blow the the trans apart from the spiders spinning and cutting the pin in half. For setup you run less air from left to right for stager to go around corners and with the gears harder than the shaft it eats it up. For some of the rwd classes they have to run a mini spool with just the pin making it solid. If you work on the PS a little it does not take away any hp. 99 % of the all the dirt cars and nascar run PS. Its a old wise tail now days. How many time do you hear that somebody lost there PS and fell back out of contention, back in the day when nobody had it took a man to drive 500 miles. Tom

Tom, I know that dirt tracks can get really "sticky" but, as I'm sure that you know, it's nothing like a "glued concrete" starting line. And there's not much need for P/S on a drag strip. Taking off the P/S pump and laying it aside was worth .08.

I see they have made the P/S more efficient. In '64 it was worth .1 on my brothers '62 Olds.

Gm systems run a lot of pressure. When running a gm pump with a Mustang II rack you need to drop the pressure or you will blow the seals out of it. Borgesen makes a simple kit for this. Not to be confused with the flow reducers with a smaller hole in them. Gm also has a cold climate PS Fluid. I did not think it would slow the cars that much but your testing shows otherwise. Saturns have electric PS and have plate over pump hole, bolts rite on. I am told the VUE cams made more torque but they do not have the drive for PS. I have one if you want to try it. Tom

Just FYI, due to this post, I have been convinced to build myself a dime rocket.. So it wasn’t for “Nuthin”.. Just letting you know!
