the Prisoner
LZ:
Hello friends and hope all are having a great year so far.
Nice to see some new people and cars coming aboard.
So anyway a little update on the Prisoner.
The cam is here.
and a shot of pistons and rods from Venolia
Line honed the block in , thanks to Matt Shaff and Ken Nojay for pointers. Had not used this machine before.
Because of some good OT at work am upping the Crank budget and am deciding between a Bryant or Callies.
So slow but we will keep at it as possible.
Thanks for watching, BCNU

Keep at it!

Well well well. Its been awhile.
So when you're feeling like " Im never going to get this done". Were all in this together. Gotta keep moving.
The Cranks here. Took longer then quoted but she's a beauty and I don't feel worthy .
Hoping to get a bit of work done next week and will post if it happens.

My experience on 12" wide rims, with the 31x12x15 D2585, and the 33x12x15, D1288 is it looks like , by looking at photos going thru the lights, is 2585's grow at least 2 , and the 1288, less, because they weigh 31 lbs, and grow less.
But I assume you are asking about tire growth trying to figure rear gears, expected MPH, & rpm. With looking at the RPM's , gears, & MPH, I have found that the 2585's grow a bit more, because they are lighter [ 26 lbs] and with narrower rims they also will grow more. But the bottom line when I look at my RacePak, and ET slips, it looks like if you just plug in the tire dia, ie 31" [ 2585] or 33" [1288] that the RPM is very close to the MPH when using one of the on-line formulars. My 2585's at 190 mph matches the ET slip by using tire dia of 31 1/2". Which of course doesn't make sense compared to the photos, but what we have going on is the converter slippage. So just figure 1/2" more, like 31 1/2" or 33 1/2" to figure on gears, RPM, & speed. i helped out another JF car when he was having traction problems, at the hit, with his 2585's on 11" rims, I let him use my 2585's on 12" rims, it helped, he ran a 7.04. But he did not like the 12" rims because with his 387 ci SBC, he ran lower MPH, because he couldn't pull the wider rim but he would smok'm more often. Part of the difference in our two cars combinations, is his was superlight 1355 lbs with driver [ that's why he built the smaller motor at 3.5 bls per ci] But with his motor out 50" and both of our cars had the same front axle weight, which means he was 90 lbs lighter across his rear axle = less traction. It's all about car balance.
We had two sets of 2585's one set on 11" rims, and another with 12". The 12" rims were for running in the finals at Bakersfield, when the sun was down and the track cooling off.
In our car , last time racing I had 9811 rpm @ 186.61, with 4.88 gears and 9000 stall converter, on the 31 tires on 12 rims, last year at the same track [ Sonoma] we ran 190 mph also on the 31's, 4.88, and a 8528 stall converter. So you can see the looser the converter the more slipage.
Feel free to call me if you are looking for more info/ numbers.

Thanks for taking time to write up and share some info Jon.
Had an interesting conversation a few weeks ago with Mike Milsap from Southwest Jr fuel assn. Nice guy.
When in our discussion we talked tires and of course your name came up ,along with the GY 2585's. (which he was also running) . He had a set of Hoosier 31.0/12.0-15 C11 on trailer. Remembering conversation as best I can. He said that Hoosier made a few sets of these as they were trying to get a tire out to use in place of the GY 2585. He said that they were heavier then the GY but they worked well in colder conditions. Funny thing was they marked tires just as in there catalog. Did not notice any markings distinguishing these from an off shelve tire? ???. Did not ask him about what they did for his car. But he was selling them if that says something
Anyway sure will be talking to you when the time comes to replace mine.
Hey as long as I have your ear. What would be an acceptable tolerance ( spoked wheels) as far as axially in rotation ? Notice one of my hayden's wobbles a little. They came with car I bought. There beauties Jon and am honored to have them.
Guess as long as were talking, what about a runout tolerance?
Figure to log this and make it a periodic checkout.
thank you
Luke
