I was wondering if i needed a stronger Diff which one should i go for.

Sub-Zero

Depends! Stock and drives hard.

1. Cryoed only!
2. FI and races: AP1 Cryoed with reinforced caps.
3. FI 500+ HP and races: Fully built Puddy built or Inline Pro full setup if you can afford it.

All of this is depending on how hard you drive and launch. I have been driving for over a year at 500+hp and no problems with a cryoed rearend, reinforced caps, and a custom Puddy solid crush sleeve. That should be good for over 600hp and hard driving but no dropping the clutch.

These are all approximations off of what I have seen over six years.

I want a diff that will withstand abuse, and digs and most likely 700rwhp. Can the puddydad diff withstand this?

PrimoGen

digs in our cars are never a good thing. at the risk of flames....The S is not a drag car!!!!

The dif may, though you have to worry about other things.

Tranny (transmission)
axles, mounts.

PM the puddydad and ask him.

I have pretty much the same set up as Sub-Zero. I have only been driving the car for a bit now, almost 5k miles and have not had any problems, and do not expect. I just don't launch.

Sub-Zero

Raven is right. Hitting an S hard at 700hp the tranny, motor mounts and axles will go before a Puddy rearend.

The big question is how are you getting 700 hp?

Good question Jeff 700

I built both Sub-Zero and Rvens rear diffs along with this one as well

The guys at S&R drive the Sub-Zero car and have a good amount of fun with the 500 + Hp the car is putting out

If you plan on hard driving and some drift action then you will need an aftermarket LSD as well

Im thinking of building a motor then boostin it. anyways im gonna pm you puddydad lol.

Sub-Zero

I have got a S & R Performance built motor at 21lbs of boost it is only 561 rwhp on a 93 octane. That is with a small Garrett journal turbo and Mase got 616 hp at 26 psi on a Laskie built motor. 700 rwhp is really hard on pump gas and you will spend a lot to get there so if you can afford to get the car to 700 rwhp you should at least go with the Puddy Big As_ rear!
