viscous coupler welding?

[swifteagle]

Anyone know if you can just weld the up the back of the viscous to make a vce for dyno use? Or do you have to turn it down and then weld it.

The outter shell needs to be cut off to get to where it needs to be welded. It takes about 5 minutes on a lathe. If I had a VC laying around, I'd whip one up and do a write-up. I used to have a whole box of VC's years ago but I think the garage ate them.

 

[swifteagle]

I have a extra one

Where do you have to cut it?

Post a pic of the front of it and I'll mark the location.

It's been a good 6 years since John at TRE showed me where to cut, but this is about where it is. Just go straight in with your cutter and once you get deep enough, the outter sheel will come free from the center. Then, clean up both center pieces and weld them together along the seam. The viscous fluid smells pretty bad too, so be prepared.

on the inside of the red line?

 

[99gst_racer]

Turn the entire area in red.

Ok tomorrow i'll start on this and see what happens.

Very good info.

Viscous after cutting.

I'm not sure if this is the best place to ask this but will this make the car RWD, FWD or 50/50 AWD?

and a pic of the vce done. I just used a 110 mig with gas but make sure before you weld to clean it very good.

It will lock your drive train. then you can take the tcase out to make it fwd. Our I guess you could take the front axels out and it would be rwd.

Ps. If you have a welded center diff you need to put the pieces on the trans and tac it together so it will be clocked right.

 

[Miakehl]

So if you left all the axles in place it would be an even 50/50 split front and rear?

The reason I ask is I've never really liked the FWD biased AWD systems, an even 50/50 split all the time seems like it could eliminate what few traction problems high HP AWDs have.

Isn't welding it up basically what was done here?
VISCOUS COUPLING ELIMINATOR (VCE)

 

[swifteagle]

Yes it locks it so yes 50/50 and it is the same thing that shep sells for 100$ But its not good to run it all the time unless you have a welded center diff.

 

[99gst_racer]

Nice work!

 

[swifteagle]

Thanks. I like your compound set up.

is this okay to do with a 4 spyder center diff? and what are the down sides to locking in 50/50 for street use? does this create wheel hop? i thought wheel hop was accociated with center diff welding. anyway i think i need to do this because i keep spinning the front tires off at the line.

Have you ever thought of spending money on setting your suspension up the right way? Judging by what's posted in your profile, your setup is far from optimum as far as getting any kind of traction on street tires at the track goes.

I have these

But i dont have bump stops from koni for them so yah ive thought about it.

So instead of putting a band-aid on your problem by welding your VC, why not fix the problem and put that suspension on your car?

 

[Archer Fabrications]

And I'm pretty sure welding the viscus coupler doesnt just make it fwd. it makes you have 4wd and with that you can choose to drop the drive shaft and be fwd. am i correct?

A welded VC or VCE (same thing) will make the car a true 50/50 split with the TC left in place. It will also allow you to remove the transfercase and run the car as FWD if the driveshaft is removed, or on a dyno stationary.

 

[dsmcurse]

correct. go to a 2wheel drive dyno if thats all ya got, do a phatty huge FWD burn out to show off for the girls, you know, these kinda things

Band aid?? If welding it give you a 50 50 distribution of power to the front and rear? Why is that a band aid?

I dont need to be fwd for anything magnus's dyno is awd. I wanted to do this only for better 60'
