As subject says is n20 safe on a stock rearend?

 

broke mine on a 100 shot.

 

Depends if you are running slicks or not. If you launch on the nitrous with a six speed the days are limited. I had an Auto launching on a 100 shot.It held up but I had traction problems. 60ft was a 1.89. I used the TA-Girdle and stud kit to make it last.
Now I have a 9 inch.Cant wait to leave on trans brake.

im gonna use dr and im not gonna launch on nitrous ill have a window switch for probably 2500 rm the lowest and it will be a 150 shot

 

150 shot, your rears days are numbered, plan on a 9" or a 12 bolt.

 

would a t/a rear girdle help

 

On my stick, I plan on shooting only 100 in 3rd, 4th, and possibly 5th. Got 4.10s and an Eaton Posi, can't get traction in 1st anyways.

 

Sorry to say but a M6 + sticky tires + 150 shot = Rears usually last awhile with A4's because of less drivetrain shock. I'm still running a 10-bolt in my car.

 

can you please exlpain what a twelve bolt is , also what a 9" is. please

 

its a stronger rear end, if you count the lug bolts on your stock rear there are 10 a 12 bolt has twelve. The gears are bigger and hold more power heres an article about the two http://www.carcraft.com/techarticles/1038/index.html
The only downfal of these rear ends are the price, look to pay at least 2000 bucks for a complete asembly

 

a twelve bolt is a GM rearend that was used in older muscle cars and Gm trucks....it can take a hell of a *** kicking with no problems...

a 9 inch is a ford rearend and will hold just about whatever you can throw at it


the 12 bolt vs 9 inch is a toss up.....9 bolt will hold a tad more power..but the 12 bolt cost less money

 

thanks alot for your replies,

 

I use a 150 wet shot in 2nd, 3rd, and 4th gear at the track. I have Nitto Drags on the 10 bolt with 4.11 gears.

I think that if I ever sprayed in 1st gear with slicks, the ring gear would snap the instant the clutch engaged.

Besides I am having a hard time hooking up with drag radials and 4.11 gears just with the power the motor is making NA.

 

how do u spray in only a certain gear i thought it was just a wot switch and a window switch

 

You can add another button in series that only works when pressed. So, it is like adding another safety switch in the series.... could be a thumb button or another micro switch.
