nitrous windows ????

hey guys i just ordered my nx kit and a msd window i have a ? abou the window i was wondering if i shoul dhave it turn off befor my car shifts(i have an auto) or let it go through? no if i have it shut off befor it shifts will it make the tirs spin when it comes back on? and will it harm my rear end? also i was wonder what u auto guys pills you use for the msd window thfor forr all your help.:D

Depends on how long you want your tranny to last you. 4L60E have a tendency to go down the tubes > 400 ft. lbs so you're asking for a rebuild if you spray through the gears.

Some people spray right through some people have it shut off a couple hundred RPM's before their shift. Completely up to you.

How big of a shot do you plan on running? You shouldn't spin after the shift since you're still putting your normal NA power to the ground during the shift....and I doubt you're going to be spraying a 200-300 shot.

Shouldn't harm your rear end.....unless you decide to spray from the hole with slicks. Then you're taking a chance. The great thing about auto's is we can preload the rear a bit by braking and bringing up the RPM's. Makes your launch less strenuous on the rear end.

all im goign to do is a 75shot and at the track maybe 100 but prob 75 the hole time

You should be fine but you may want to limit the times you spray through shifts.

The clutches in my tranny are already shot so I'm going to a built TH400....my last dyno before headers, cam and rr's was at 376tq so I knew I have been pushing my luck on how long this transmission is going to last before a rebuild.

Go easy on it if you don't have the means to do a rebuild...but like I said, I wouldn't worry to much with that small of a shot.

well will it be a lot safer to stop it when the car shifts i already bought the windo for it so it not a big deal i just didnt want the tirs to spin every time i shift

It'll be tough to spin the tires with a 75 shot when shutting off for the gear change.I would recommend shutting it off when the car shifts.
I spray through shifts with a 4l60e,got about 5 months out of a 100% stock trans.
I had the 4l60e built,and went a season and it still shows no signs of wear. The trans is coming out and getting replaced with a th400,mainly cause the new combo will destroy the 4 spd.

k cool and last thing when should i make my nitrous come one do u think about 3,000 that sound good?
