Enemy's new ass... AKA moving the Jeffco

[Enemy]

Ok, I am going to try and remain as calm as possible while I do this first post...... 
Here it goes.

Dear Jeffco,
 I had to find as much extra chain length as possible to help combat my extreme chain heat issues that you provided absolutely ZERO information about with the exception of "What other people are doing BS". (seriously! DS has the pictures to prove it!) This is what's being required to gain 10 inches of chain without scraping the entire friggin' rear subframe of my car.
This is where the box was >


And this is where I'm going to put it (I'd REALLY like to PUT it somewhere else but I'm in a good mood today!  )>


P.S. Jeffco,

SO now that I got that out, here's some pics of progress toward the new rear suspension ideas! Woohoo!




 Much more to come, but I am now off to slide down some snow packed mountains...Hopefully still upright!

How many tooth sprocket is that on the gearbox?  Is there an option to leaning the gearbox back?  Last question, what is the rough measurement from center to center of your sprockets?  Sorry about all the queations, just reading, and learning....

Rear count is 28. Center to center on the shafts is now 12.5" where it was 9.0". Rocking the box back will only gain so much chain before running out of adjustment with the current plate or moving the motor entirely (not an option)
 I am doing this redesign on a very tight budget, which means using what I have as effective as possible. (and not cutting the entire back half of the car off!) Everything has to fall together  very precisely on this and thankfully so far it is. We got a lot of brains and a lot of great ideas going together on this one so check back often! I will get more posted up later, but it is Va-Ca  time!

Hope your done for the April trip so I can dust your ass at the drags!

[dsrace]

I'll be right beside you! 

enemy you are doing one hell of a nice job moding that unit and after the test runs with the 530 chain and larger sprockets I do believe extra length will get you the run time you are looking for!!

as for the jeffco box, so far the box has held up nicely but the lack of info in black and white and via phone calls is very discouraging! if you are not going to offer the live spool and inboard brake then change the box so the flanges are centered again and please tell people that you recommend a 14" - 16" sprocket center to get a full season out of a chain! that is very useful info that goes a long ways in the beginning of the build rather than after!!   also for future reference to all others that want a 5-1 final drive reduction like enemy's go with the strong 530 chain and an 18 tooth counter shaft sprocket and something like a 32 in the rear I would also recommend spending the extra money on the sprocket hub they ONLY OFFER IF YOU ASK  ! I don't know what the bolt pattern is but I believe it's a stock suzuki so you could buy sprockets from sprocket specialists in any tooth count you want!!

enemy I know we'll see you there in april, when your ready give me a shout and I'll swing buy and help you finish it.

One more day of skiing and I'm gunna get right back on it! Those new tabs ya had made are friggin' BRUTAL DS! I got the upper tabs tacked on before I left Thursday and the measurements are looking very nice on the new upper A-Arm bars. Get ready for that phone call!

Ok, brain is going crazy tonight thinking of different ways to finish up this design on paper..
I'm pretty much set on how I'm going to do this but I have something that's been bugging me since day one that I have not found a definitive answer to...

Question:  On a rear disk brake set-up, what the HELL is the difference if the caliper is located to the rear, or to the front of the rear tire!!?? I'm getting mixed feedback on this. All the conversion kits I look at for the street, the caliper is located to the rear side of the tire on solid axle trucks and cars. On my '66 F100 with an old school Lincoln Town car rear disk swap, the calipers are to the rear. I'm getting hints that it has something to do with anti-dive?? Just something that bugging the shit outta me once again!! (I hate it when the brain wont let this go dammit!)

Any thoughts guys? Chime on in here! I cant friggin' sleep :-\

On an independent rear suspension there is no  difference where you mount the caliper as far as anti dive is concerned. On an independent suspension antidive does not happen.The  difference is how clean the pads/rotor stay. In front and on top wil tend to drag dirt/mud between pad and rotor whereas a   rear mount will tend to dislodge dirt/mud and have it fall away instead of ending between pad and rotor.

[Enemy]

Thanks Master! That makes alot ( ) of sense!

I may have to do some rethinking on this and change it up a bit...

[fabr]

There is a widely accepted misconception as to how antidive works.

[fabr]

Personal opinion is for primarily dry sand it makes little difference where the caliper is but if there is wet sand or mud then ,IMO, rear mount is the only place to mount them.

[Nutz4sand]

On an independent rear suspension there is no  difference where you mount the caliper as far as anti dive is concerned.

 I agree with this above... BUT... It disagrees with this you said below. 

On an independent suspension antidive does not happen.

Also I do think you can induce antidive with with brakes on an independant suspension.

I needs clarification here! I is cornfuzed!

Enemy I am guessing you already figured this out but will moving the box back affect the driveshafts enough to worry?

I will be introducing about 3* of compound angle into the shafts if I keep my current (desired) wheelbase. I had around 1/8" of plunge on the shafts with the old position of the Jeffco, so HOPEFULLY will not be increasing that amount by too much. I just picked up all the material to build some jigs for the arms so I should know exactly how much by the end of the weekend if all goes well! WOOHOO!
