Yes. a lot more time. But everything else adds up to about the same as an SS.Crash Enburn said:

I may just be guessing, but I think a good unlimited adds about 120 to the SS's 150. More when you find out you need extra bearings, because my tests indicate that only about 25 percent of bearings are what I call "outstanding", i.e after prep need to spin over 120 seconds. Also, winning wheels (w/o bearings) are really fragile for a car to place in the top 10. IMHO you just need a full set of spares. So let's say you buy 18 bearings hoping to get a really fast set, that's 180, and another 60 for the spare wheels. UNLM is a very expensive class. AND BREAK CLEANER ALSO, with an air compressor that puts out at least 130 psi.

I was actually going to say between 100 and 150 psi.
I should also add that the storage of extra bearings can also be a problem
I have purchased lots of bearings over the past years. Perhaps as many as 100. In all that time, I have had 3 where blowing them apart occurred. I have always just assumed that those 3 bearings were flawed to begin with. I may be wrong, but that's just my assumption.OPARENNEN said:
In another post somewhere on this forum, I posted my test results on a large number of bearings. I bought most of these directly from BOCA. I found that in testing a large group, (now I am only going by memory):
10% were absolutely deficient.
15% were usable, but only for "outlaw events" where just entering a bearing car makes you a winner
50% were good, but not enough to place in the top 5 of any NPWDRL event.
25% were way above average per my spin testing.
in the MidAmerica event this past week, I entered my two best cars that had the super bearings, and both of them only placed around 10th. Perhaps the low placement was due to the bearings, OR maybe (my present belief) the actual wheels were not as perfect as I assumed. When I get the cars back, I think I will be able to find out.

I have several "ladder" bodies, although I frankly don't think they are as good as DD4H's X style body. The SS you are talking about at MidAmerica, is called "Blue Hole". That body might not be as fast as other bodies, but with the transparent top, I thought it looked really nice. BTW, that car has fenders both in front and behind the front wheels, plus a thin side piece connecting the two fenders. That was all done for beauty, and not necessarily for speed.OCDerbyDad said:
However I normally modify the X style body thinning it down to 1/4", removing the single "cross bar" strut, extending the front triangle hollow up to just behind the front axle strut, and adding another hollow just in front of the front axle.
IMHO, if you cover the entire body (either front or bottom) with 1/64" birch, you really don't need the X section at all. Just leave that whole middle section without any X or ladder support.
John (DD4H) now has a body that I believe is superior to all of the above. He creates a single hollow section that goes all the way from the rear axle to the front axle, and then in the weight section just behind the rear axle, he mills out at a different depth. Thus when you thin this body down to 9/16ths, the weight section has a 1/16ths top, but in front of the rear axle, it is all hollow. I'm currently creating two new SR's and one SS using this new body, and I like the results.

Come up with an idea, and if it's viable, it can be done. John and I designed that body, I'm glad you like it OPA.

Obsessedderbydad said:How does one get a hold of these few ideas?
In my case, I sent in a body design to John and asked him if he could do it. He said to me: How about this instead (I am assuming that's the body Kinser talked about above). I simply said: Good make me several, and he did right while I watched. However, after receiving four of them, I added hollow holes in front of the forward axle.
I'm not very good at posting pictures, but if anyone wants to see the final result and can accept Text messages and pictures, PM me with your phone number, and I will send you the picture.
I didn't know that was an option! I have a drawing of what I want with measurements... Does that work?
