Brent B, bbrock,
Interesting. Nice test rig. Did it bind up where the horizontal upper board slides on the vertical members? It seems that might give a false reading. How did your spring rate? (IMG:style_emoticons/default/idea.gif) |

It seems that might give a false reading. How did your spring rate? (IMG:style_emoticons/default/idea.gif) No issues with binding. The mortises the uprights fit through were cut really loose (almost a half inch oversize). The uprights just held the top board in place enough to let me snug the nuts on the all-thread without flopping all over the place. The biggest problem was that stupid scale. It only reads for a few seconds so in the end, I wound up have to just heft the top board down with my own weight and quickly read the damn scale when I got down to the 1 or 2 inch mark. Springs tested at 50 lbs. give or take. I decided that was close enough to stock rates to clean them up and use them. Engine isn't in the car yet so we'll see. Based on the test result, I gave them one green dot. (IMG:style_emoticons/default/lol-2.gif) (IMG:http://www.914world.com/bbs2/uploads/post-20845-1551674284_thumb.jpg) |
