FC3S Differential Pinion Brace (By Ray Platek)

[digitalsolo]

Glad to hear it's doing well, Don.

I can't believe you'd have any trouble with that setup.    Let us know how you like it over time.

Went to Great Lakes Dragway today to test the pinion brace.
Wasn't my best 1/4 mile but it was my best 60ft on street tires. I give that to the pinion brace.
Had 2 comments from guys in the stands that the car didn't squat and it shot out like a rocket.

I might have had much better times but a kid sprayed his tranny all over the track and proceeded to drive across the lanes to make sure he destroyed both sides. They tried to reprep the track but it was still slippery. Oh well.

Good Info Don and Ray.
I will do that mod the minute I tear my front diff mount. 
How long did your diff mount last before breaking?

About 7 hard launches.

A traction bar for the FC, woohoo.  If you would add a truss under it and extend it 3 or 4 feet farther forward you would have a ladder bar like we used to run on our old shoebox Chevys.
 
Don, what springs do you have in the back?  Jeeeze, get some tires!

You said it before I did........Ask Santa for some real traction, and get the job done!

Okay Don, between myself and Ray we are going to help you.  Get some big ass M/Ts, let 'em down to around 9lbs, put, oh say, 5000 rpms ( I know you can go over 7 ) on it and sidestep the clutch.  Then immediately grab second and go from there.  Right foot flat on the floor for the shift.
 
I guarantee that will work,  that's the way I launched my old Plymouth.  If it doesn't, you will need to install the Ford diff that you've been dreaming about anyway.
 
Happy Turkey Day everyone!

Hey Jim,
Just don't have the cash flow for wheels and slicks right now. Maybe next year.

I'll finesse my times on street tires then when I do get slicks I'll be perfect. LOL

So you like the new brace huh? 

It worked pretty good on my auto trans as well, tho I still had some wheel hop til i went with the 929 axles, poly bushings throughout and later new struts, after that I was pretty good. I'd still get a slight tire shake on drag radials once and a while but not much and not for very long. However the 8.8 solved that and everything else combined to make mine so stable I have zero fear of spinning til my heart is content lol!

Add some traction and I'm going down the track now lol. Cant wait to see what the Z06 cam will do this spring lol!

Yea Bill the brace works great.
With the MMR bushings and my springs and shocks it launches great.
When I was going through the water box they spun great. I try not to spin on launch but the track was pretty slippery from a previously blown transmission from another car.

Well then some good tire should put you closer to 1.5 60's and a little better 1/4 mile. Now you know what to ask Mama for for christmas!

Don will be happy then!

I gotta sell the 17x18 ATS (Mustang) rims with tires I have on craigslist and then I can buy some slicks.

[jim3]

Good luck with the sale, Don.  What do you have in mind for the back?

I'm not sure. I'll probably just get some 15" steelies with MT drag radials.

I ran Ray's 16x9.5 Hoosiers one night at the street drags and had NO traction issues at all. Did'nt seem to matter about the tire pressure though my car is stock(ls1). They were on 16x 6.5 acura rims too. If you have to spend money on tires, I say at your power level go with a set of those. DR's will probably leave you somewhat disapointed especially if you plan on more power later in the game. I know mickey's are better then Nitto's, but launch is where you make the most time up so slicks is a no brainer here.
 

Thats where I'm going next lol!
