Ya, I agree with French store in cool dry dark no electric motors , place. Best wraped in plastic.
We are racing GY's made in 2016, changed at 2020 MM , just because GY just made a new batch.
GY suggests replacing slicks when 60' times get worse with no combo changes.

You just need more seat time you'll get use to it. In my dual engine Top Gas dragster my eye line was in the middle of the blowers, a 6 foot tall guy could stand at my front axle and I could not see any part of him. Just drove in perspective so much on each side
Our driver complained at first trying to look around the offset 20 amp MSD in our Heritage JrFuel, but as he had more time driving he just is  getting use to it.
i don't like bar stool drivers , don't look right.

I agree with Bruce, need photos, but I think the big tube hole is for a tubeless valve stem, not a tube

real nice work Bruce !

yes I agree Neil & Parks Racing 785-422-8722, in KS
It is a good idea to have it made out chromemoly, at least 5 feet long, with no vertical supports to keep it somewhat flexable so it will not hit the WB so hard it will unload the slicks.

Wanted to buy / Re: wtb pg torque converter
« on: May 29, 2019, 05:10:58 PM »
What size, 7", 8",9",10" I highly recommend A-1 in Washinton they know FED and have built ALL of the JrFuel converters and most of the Comp Elim too.  360-574-9966, Adam or Alan

Bruce, I have built a few tall 21" wheels, with 28" tall tires, that they race full tree classes, Comp Elim, Top Dragster, with legal offset axles, which of course gives them great 60' times, and reaction times, because they are blocking the beams longer. I compared  two cars roll out , one with 17", and one with 21" , the 21" has a 4 1/2 " head start on the start line. No red light because of 3'rd beam problems.
No advantage with a pro lite tree.

Bruce, then nobody needs light shields ? Then why when we raced Phoenix did ALL of the cars without shields red light and all that had light shields not red light ?
I witnessed a red light problem at a national event at Vegas with a Comp Elim A/AP when it red lighted without moving [ video] , not even tire wringle, NHRA tested and tried to doublecate, and NHRA decided that a photographer standin shooting at the startline, outside the K rail , was the cause of the flash camera reflecting off his front wheel because the photgrapher was actually shootting his competitor because they left 1'st. That's why NHRA does not allow photos at the start line now. Allan Ellis has since blacked out his wheels. 
How's Dennis Murphy car coming along ?

Yes , I think 9 lbs is too much, but it also depends on the brand of slicks you run. Call the slick manufacture for pressure suggestions.
M/T seem to like around 7 #, I use mostly 6 # on our JF Goodyear 31x12x15. Keep in mind the 10.5" tires are designed for the 10.5 class 2500-3000+ door cars not FED's, but I know of some teams running well with 10.5 tires like the NHRA Comp Elim points leader now is A/ND [ JrFuel type car] running 6.80's .
You also posted that you hit the wheelie bar a number of times, I have suggessed to a number of FED racers to add ANOTHER 20 lbs on the front end, and they run quicker I think because it will not hit the wheelie bar hard and unload the slicks, plus it may run straighter because you can steer it. Add more weight if you think you need it and then take some of the weight off to get the weight balance where your cars wants.
I know of some teams that run a total of over 100 lbs.  Less if their engine is further away from the rear end.   
What size and brand slicks are you running ?

Wow, Greg, 500 rpm under stall, that would be way too high for us , we stall 8500-8700 with the SBC JF car , but what seems to work good for our car is leaving around 6400 rpm giving us 1.01-1.04 60' times. Keep in mind the higher you launch at the quicker the RT you get.
Again it's all about your combination , Greg you are running a blown alky SBC, running in a breakout class, we are running a 10k rpm injected alky no break-out JF . We need to get some tire spin going at the hit, yours makes more torque because of the blower, and you no-doubt run a 8" tighter converter than my alum light weight 7" converter. I still run a 7" but tighter converter with our Hemi [ more torque].
We shift at 9600-9800 rpm with the SBC, and 9500 with the Hemi.
How high you launch has to do with what RPM the motor comes on at, track prep, tires , tire pressure, rim width.
The other issue is tire shake, I think tire shake is caused by TOO much bite dead hooking then unwiding of the side walls. Too much bite , I let some tire pressure out so the tire works more on the edges of the tire thus reducing the footprint . To check that out I use my temp gun at the turn-out and read temps across the tire, ei hotter on the edges. On our Gooyears we run 5 1/4 to 6 1/4 lbs, depending on track conditions. i have heard as low as 4 3/4 with bead locks on a low torque engine combo. My  GY guy has said that more and more racers are having tire shake issues because the tracks are over preping the tracks [ TOO much VHT] that is why I'm going to try some other tires, like 31x10.5wx15 M/T and M&H. No doubt I'll need to try different tire pressures [ MT like high pressure] launch rpm , and rim widths.

I agree Hoosiers are track temp related, even with my JF Goodyears I will not make a Qualifying pass if the track temp is in the mid to low 50's , it just will spin not even smoke on the buern-out , just spinning.
If you are running NE-1 [ 7.60] NE-2 [8.60] you can run some nitro and some not all teams run nitro. if you are running under 50% no compression ratio change is needed.

Wanted to buy / Re: advanced ET roller
« on: May 25, 2019, 12:16:47 PM »
Justin, I know of a few FED for sale , one is a roller JF car with out engine or powerglide, in Phoenix it has won NHRA Comp and Heritage races.
 I think his engine is out 44" with 225" WB, he also has a trailer that will take a 225 WB car. Also there is a JF roller for sale that will require some work, last time out the air bag under the car broke and some tubing will have to be replaced. I think its 185" WB with the engine location at 44" it was running a Ford so as with any car you get , you'll need motor plate and front mounts. This chassis is in the LA area, last I heard he wants under $5k. In Walnut Creek there is a JF 185"wb roller for sale racing the last two years the engine is 42" out I think.
So call me if any of that is interesting
