I saw 20k lb in one of the descriptions but was hard to find.  I do plan to call them.  I was hoping someone had experience with them.
P.S. Will you be in St. Louis next month?

Tow Vehicles / Dynamax Force HD Motorhomes
« on: July 25, 2016, 09:17:05 AM »
My wife and I are looking to get a Dynamax Force HD to haul our car and enclosed trailer.  Eventually we want to upgrade to a 2-car stacker.  Has anyone had experience with this brand an model?  They have 350hp Cummins 1000 lb torqe.  20k lb towing capacity.  The one thing that concerns me is the overhang past the rear axle which is 11 or 12 feet depending on exact model.

Thanks, Chris.

Call Dennis Young for the availability of Aussie heads @ 714-321-6133. Tell him a friend of McKrays gave you the number.
Thanks.  I will call him. Does he have iron heads?

The car is 184" WB.  1214lbs on rear, 338lbs on front.

Update on my 7.80 pass. When I got home I read the logger closer (had to pack up quickly as my wife had enough) and found that on the last "all-out" license pass 1 plug was closed up all the way and 2 others were "re-gapped" to .010 for me.  I checked the bearings, no issues, just not enough piston to plug clearance.  So, I'm expecting more out of 8 cylinders. Also, I took 100 lbs off the car over the past 2 weeks.  Now down to 1552 with me in it.  I can't wait for the NDRL race at Gateway.

Thanks again to all of you for the help.

Hi Drag:
Once again way cool with the 335. Love those engines and great to see one in a FED.
So am I seeing high port heads in that photo??  Did you do them or are they older heads? Are you using them again or going to an aftermarket on your new heads?
Thanks for posting on your gr ogress . This is way fun to read about.
Luke
Thanks for the complements.  I did these heads myself.  The new heads are done the same way.  I'm not aware of any aftermarket iron heads that are in production any more.  CHI used to make an iron version of the 3v head.  They quit and I haven't found any for sale.  I have a complete 429ci Windsor smallblock with c302 heads that I may drop in sometime and run the 7.50 pro NDRL class.  For now my goal is to run 8.00 and sqeeze as much out of this old Cleveland as I can. 

I bought my first fed when I was in highschool (wanted a fuel altered, MOM said NO). I put a real stock Boss 302 in it and ran 9.50's.  Then I built my current car from scratch in 2005 with a stock 351c and ran 8.50's but burned up parts right an left learning the whole way.  Wanting to get into porting, I built a flowbench and started on a set of Cleveland heads for the car.  Needless to say, I'm still learning... These heads on the car flow 315 and I have a new set that flow 330.  My goal is 360 or higher.  I've thought about designing a new iron head and having it cast(something that would flow 420 or so).  I've laser scanned the stock head and have played with it in solidworks for a bit.  I had to stop for a bit and kill some cancer. But now its game-on!

We were just talking about tires in another thread ! Is the Hoosier you are running a new tire ? I had heard that they were working on  A new Junior Fuel tire . Sound like you are heading in the right direction with your car !
This is not a new tire as far as I know.  These were out at least for 2 years.  I was looking at them 2 years ago but was not smart enough to know I needed them.  The folks here got me on the right track.  My car was so violent with the 8 inch converter and the old 10.5 tires that I couldn't make more than 3 passes without severe back issues.  Now it is so smooth it is somewhat boring.

Congratulations. Can you share with us the weight of the car accross the scales; rod length; and who did your heads? You might consider shortening the ram tubes when they get near the top of your 'Bang for the Bucks' list. McKray built a 406 Cleveland-Head Ford (tall block, long rod) back in the mid 1990s that was promissing. That car was sold to a SWJFA participant who in turn sold it to the Frye Bros of Ohio. They had a crash and a trailer fire that greatly affected their racing.
Thanks. The car is 1650# with me.  Im 218. The rod lenghth is 6.125.  I did all of the head work.  I'm no expert but have a local mentor who is.  These are not the good heads.  I have a set that I'm working on for the next motor that have many more hours in them.  The tubes are shorter thsn in the old pic.  Here is a pic of the new motor.  I've also invested in a dynamic cylinder pressure analyzer from TFX that also shows the intake and exhaust pressure waves.  I have done some preliminary dyno work with it.  I'm still learning about what to do with what it is telling me.

Thank you all for the help and advice. Over the winter I put in a new A1 7 inch billet aluminum conveter, 4.56 gears, 12 x 31 Hoosiers, new Weld 2.0 rims, and set the wheelie bar at 1.5 inches. Last night at Gateway I finished all of my licence passes endind with a 7.80 at 170.  1.140 60 ft.  No violence at all. The converter is stalling 7500, shifting at 8800.  The converter ratio at the trapps was 1.05. Still spinning too much but getting closer.  I didn't want to experiment too much. I just needed to get my licence passes in.

Here is what the car looked like before the new motor and smaller tires due to Good Year discontinuing the 30 x 11.5 I had.

Thank you all for the input and advice!  I think for now I'm going to get the Jesels installed, lengthen and lower the wheelie bar, get the gear ratio right to turn 8500 thru. the traps with the 31x12 tire.  I may play with the 10.5's a little because I have them but I see the 31x12 is probably where I will end up.  As for cutting the car up, I did that once before to get to this point.  Not a problem but my plan is to learn what I can with this car and graduate to a real Jr. Fuel car in the future. I've attached a pic of the old car and the new car.

masracingtd1167,  If you don't mind, what is the part number of your Braille battery?  I'm probably going to go to a mag over the winter but if not I'd like to use a light-weight battery.

JrFuelHayden, I was concerned about the 18v Milwaukee battery burning up the datalogger or is there a voltage regulator built in to the battery mount.

JrFuelHayden, I'm running 9 to 10 psi and the tires wad up and shake to the point where you can hardly see.  When I get it back together I was going to play more with tire pressure but I'll try lower as well. I have not had a good 1/4 mile run with the new motor but it looks like I will have to drop a gear ratio with the 30" tire and maybe 2 gears with 31". I'm currently goin thru. the traps at 7800.  I need to be at 8400 to 8500.  What king of rpm drop do you see at the gear chenge? I feel mine drops too far (8500 to 6200). I attached a data log. My converter is a 2-piece 8" that I made myself.  I've played with 6 or seven stators to get the stall where the motor likes it.  ~6500 to 6800 seems to be ok.  60' times wer better with lower stall (5800) because the car would dead hook and bend the wheelie bar as it tried to flip over.  The higher stall get the motor in peak torque and now spins the tires before it touches the wheelie bar. I'm looking for the best scenerio but I admit I'm a bit lost.  I'm going to got to remote start battery and install a new mag.  I would like to conver the front wheels to 17" and will give you a call at the end of the season.  Does anyone make lightweight modern spindles for that hub?  I want to get rid of the bellcrank steering and run the sterring rod out to the spindle to make room for centering up the fire bottle and reduce backlash.

Thank you all for the input.  Looks like I need to go to a mag and remote starting battery.  Any issues with running a data logger on 18v? What is the best mag setup for jf? Thank you all again.

Roo, Here are a couple of pics.  See what you think.  I can post more if there are some details you would like to see. Thanks for your help.
