quick question with probably endless explanation.

how durable will my D36 be if I up the HP to about 300-330 and put drag radials on it. I have seen the 7.5 last with slicks and 5000 RPM launch and I have seen them break on DR's


who has a D36 and has beat on it and it lived?
who has killed them?

 

Simple answer IT ISN'T.

Look for a Dana 44 or make sure you "AAA" is up to date.

 

come on, it has to take SOME KIND of abuse, something? anything?
I am not planning on doing any hard launches or anything, just some rolling full throttle hits.
it will not be a drag car.

 

I have an 84 with a 550 hp stroker, 3500 stall, 700r4, d36 with 3.73. ON 315-35-zr17 sumitos it has lived with lots of beating. I am concerned that the day I hook I will be making chicklets but 3 years and I am still going.

 

It might break on the first pass or it might wait until the 100th pass, but it will break

I see you use the operative word "PASS"
if I am just using it for everyday driving, stoplight to stoplight fun and never any real hard beating, it COULD (again, another operative word) live for a long while?

 

I think it will hold up for awhile then, under those conditions.

Remember, the Corvette was never designed as a drag car. If they had intended that as it's main purpose it would not have the independent rear suspension.
It's the hard launches on really sticky tires like drag radials that will kill the D36. Put enough power down, and the D44 won't hold up either.

 

screw that, talk about a ton of work to fit that crap in there.
I may have to skip the nitto tires. I am not going for much, I just want to keep up with LS1 vette's

 

Speed costs money, how fast you wanna go?

 

HA, I got the auto so I could pimp and look good while still laying some smack down on a candy *** or two.
if I lay down too much smack, I wont look like a pimp, I will like like the bitch.....ACK....

 

mid 12's motor
high 11's nitrous

 

Sounds like a drag car to me then.

 

damn, I guess if I look at the big picture, I have been had.

now you have me back to not knowing what I want.

the more I know, the more I know I dont know.

 

Thats not to hard to do. I push 365rwhp 350rwtq to my dana 36 and eat up 90% of the C5s I see. I have 3.73 gears, 2400 stall all on Nitto 315 drgs. I usually drop psi down to 20 and run a 5 to 10 sec heat cycle befor crawling up to the tree. I see 1.7s 60' times and run mid 12s all day and a best of 12.2. I beat the snot out of the 36 and cant seem to break it. Once I break it , it opens the door for a new 44 from exotic muscle and 3200 stall from Vigilanti. That should bust me into the high 11s. Ive been told Im on borrowed time with the 36. I do wish I had the 44 in for peace of mind when Im entering the stagging lane.

 

Photo below is with 360 RWHP, I guess it's all about your combination.

 

Mac, have you busted a dana 44 with that car. What kind of stall do you run? and gears? Those are unreal #s. I was just throwing out my #s to show what some dana 33 can take. If your busting 44s you have to be throwing a high high stall and stickey tires at it. Mac, you have to be close to a record on a N/A LT1 350ci. I dont think Ive ever seen one hit the 10s

 

I have seen a guy with a big block in a 86 with a dana 36 do several 9.70 1/4 mile passes at Memphis Motorsports Park. I asked him what he did to make it hold up, and he told me that when he put the gear in it, he put all new bearings and replaced all the u-joints with good strong ones. He said he just gets under it and checks it all out before he runs it and replaces any parts the start to wear.

 

Okay, it was an early design and the power was more than doubled, but...

All I was doing was 'taking' a Bronco on the outside on a short on-ramp! In second gear, I just pushed the go fast pedal and BANG, lump-lump-lump, followed by that thick oil river. That was a 3.73 gear set with maybe 20k.

I am never real hard on any car; never dragged. My rears were 315/35x17s, a bit hard after sitting and waiting 3 years for me to get the conversion finished. They were my safety valve, I thought.
I could not find any deal on the rare 44, at the time, and my R.E. specialist spent many hours on research. He happened to have a newer (stronger) D36 case on hand and I went with his recommend to cryo treat everything, including the case (mine had split) and the 3.54s. He chose a gear set that had two (versus one) teeth in contact and explained that any tail can be broken. I opted for synthetic gear oil due to the heat of the 3" pipes being right under the unit, despite his avering that non-synth oil lubes better.

The guy is honest and hardworking and his shop in Anaheim has been around for decades. They do Vettes, Vipers, huge trucks, motorhomes, etc., and back their work. His son runs Drivelines, seen on TV, but also a great shop.

 

running a 36 in mine for quite some time w/3.73 gears and a six speed gear box....been through many passes at the drags, however always have run street tires with little traction and rebuilt it when we did the gear swap...may be on borrowed time, I don't know, but as long as I am running street tires, it probably will be fine. The car is a street car anyway, so I am not concerned about drag radials.
