Cobra Broke

[BurnTire]

Well I noticed some vibration and what appeared to be gear wine on the drive home last night. Took the car out to investigate again today and still noticed the noise and some vibration so I was like WTF?

I did some looking around and everything appears to be OK on the rear end. It didn't really make sense that the gears would wine after a track beating with a solid pinion shim, ARP bearing cap studs and a T/A girdle.

I was attempting to remove the drive shaft to check the pinion nut only to find that the yoke will not slide off the output shaft. I also noticed the bell housing appears to be a little lower on the passenger side.

So there may be a motor mount issue not sure yet.

I know for sure the drive shaft yoke has welded itself to the output shaft of the tranny which more than likely explains the vibration.

Well life is good I am getting all 4 wisdom teeth removed on Monday. I hope they come out easier than it will be to remove the drive shaft.

[Lucafu1]

damn man that sucks. keep us updated.

[MinGry03]

Bummer. Sorry to hear about the car and your teeth. Maybe you should have kept the IRS in until it broke?

[BurnTire]

I don't think this is a rear end issue. The drive shaft yoke is supposed to move freely on the output shaft to compensate for the suspension moving up and down. Well it is totally stuck. I even gave it a few taps with a hammer and it will not move. So I know that stuff is toast.

In did set a new best time last night of 10.75

When the tranny comes out it is not going back in. This will be the 4th time the tranny has been out of the car in 12 months. 4R70 sounds like a plan.

JEFF loves hammers lmao:biglaugh:

[wickedcobra]

That sucks.....did anyone get your new best on video?

[BurnTire]

JEFF loves hammers lmao:biglaugh:

The bigger the better!

[QuarterHorse]

This may sound kinda dumb but....I had a 66 Ford Galaxy 500 and needed to take the driveline out for some reason...can't remember but when it wouldn't come out I came up with a plan. I took a comealong and chained it to the front yoke and the rear axle. After about an hour of banging and winching it still wouldn't come out. Well I said the hell with it and went in the house. Came back out later and found the driveline laying on the ground....go figure. Just a thought...lol

[AZSonicSnake]

wow, not good news man! i do like the auto thought. i know if i ever have issues with my t56, i plan to go that route. :woot1:

[BurnTire]

Found the problem. I finally got the driveshaft off the car. The output shaft is bent and the splines twisted. I am surprised it didn't break.

Must have been the installer, I bet he put the driveshaft in upside down.:bounce:

[4Jenna]

Jeff was shimming his trans mount up to set pinion angle...hehe

Sorry to hear Jeff but we know thats just racing!

Congrats on the new best, and smart move if you go auto.

No big deal. I have had good luck with not breaking anything since Oct 04 so I guess I am due.

I am doing a bunch of auto research to find the best fit for my application.

[4Jenna]

Time to go real fast, and be real consistant now!!!!

If you only had a turbo you'd be set:tearsofjoy:

Do it right and put a TH400 (Turbo 400) in it!

[Dan]

that trans eats up alot of HP to turn that bad boy.

C-4 FTW and when he makes more power then do a glide

[Viper_ed]

C4 won't hold up to the abuse and the glide will do unless he plans to still drive it on the street. The 2 speed is no fun for that.

Look no further than here for a trans Jeff:

[BurnTire]

I have been doing a bunch of research on C4s', TH400's and 4R70's. I will go with one of them.

[Viper_ed]

I priced out a C4 for my 88 Turbo car and it ended up being almost the same price as doing a TH400. The TH400 will be the only tranny you'll ever have to buy if you get one that's done right.

[fazm]

its one of those things where a turbo 400 just eats more power, while a manually shifted c4 auto will take less. and we all know jeff likes to go fast lol.

ill PM you a link jeff

[Viper_ed]

and we all know jeff likes to go fast lol.
He's going to go quicker with which ever one he goes with. Hell's, he's going to need a new screen name soon.........

I'm thinking illrunitcausemineisquicker might just do. :sticktonge:

Hell I have him beat big time 10.75 running cats and less boost. I would figure an auto will knock off .3 more when setup properly.

[Venomous Bite]

After the auto you'll need to upgrade that 2.3 to a 3.4 then the stock longblock will........:hi:

tell that to the people running over 1000hp on the stocker lol


wonder how long they last at that level though lol

[4Jenna]

You will be freshining up a C4 ALOT more compared to the others.

Some have lifetime freshin ups, but not free shipping.

[fazm]

eff it, just row the gears :)

Yeah I know they can last at that level but knowing Jeff I don't think he will take that chance.

[P Machy]

It would of been fine with the IRS :sticktonge:

Spec 5- Steel Flywheel. 5000 RPM Launch = Boom IRS

[P Machy]

Spec 5- Steel Flywheel. 5000 RPM Launch = Boom IRS
Ouch!!!

Nothing worse then getting a car back up and running to only break again...

Why the Steel Flywheel again?

[chewbaccajones]

There ya go.

[BurnTire]

Inertia, less chatter. And the spec 5 can only be run on steel.

[BurnTire]

May pull the trigger on a viper spec t-56.
I am not missing all this cool weather like last year with the half shaft fiasco.

What gears are you running and how are the street manners?

What do you tach at around 65 MPH?

[wickedcobra]

I say do they Viper T-56. Im sure one of the Auto trannys will be a bit faster but there is nothing like a manual IMO. :3gears:

An auto is boring no matter how fast you are(my o2 of course)....I will never own a auto race car!!! Autos are for daily drivers lol!!!oh yeah and old people lol!!!:twothumbsup::biglaugh:

[Lucafu1]

I spoke with D&D today. Sounds like their Viper Specs are now a Cobra Core that is a direct bolt in. Just change the yoke.

For the time being a 6 speed will probably go back in.

The ultimate plan is an auto. But I am very picky and want to do it right the first time.

I know you want to put that TH400 in.:biglaugh:

[Ruckus46gt]

friends running a freddy brown manual shifted auto in his street driven 9 sec twin turbo mach. No issues either

[6Jeff6]

Running 3.55 gears and run at about 2,800 rpm going 65-70mph.
I got 18mpg driving 1200 miles back from atlanta when I originally bought the car.
Never really checked mpg after that.:sticktonge:

And saying an auto is no fun on the street is wrong. With this much power traction is the only issue and a stick would make it that much harder.:woot2:

Wow thats not too bad. Is that with normal size tires?

Also I assume you got the speedo working?

[6Jeff6]

315 35 17's bfg dr's.

Speedo seems to work good.

Remember I do have a gear vendor on the end though(like high low in dump truck). I actually used the gear vendor on top end of track. It's supposed to be good up to 1200 rwhp.
I can give you more info on how the gear vendor works if you want. It wasn't cheap but the car is so street friendly it's scary.

It will never be as fun as ripping tru the gears though!:woot1:

[4Jenna]

Ripping thru clutches and trannies more like (on big power cars)...why I tapped out on the 5 spds.

I hear you on killing clutches. Now I have a Strong clutch and it is killing the next weak link.

I am waiting until after the holidays and then I am going to get some pricing from PSR on the 4r70 and make a decision on which direction I will go.

I am going to pull the tranny as soon as my frickin jaw heals. I can't wait to see that output shaft.

[ThePunisher95]

I edited my post thats what I ment whats on there now

10.75 is you new goal Mr Spark plug.

I was scheduled for an hour to get a 4 teeth out. Left two hours and 45 minutes later. The tops came right out. The bottoms were difficult. They had to drill the bone to get the hooked roots to release. So it still hurts and it would even hurt a big muscle man.
