should i set my window switch to spray inbetween gear changes on the automatic or should i set the window switch to cut off @ 6400 RPM? that way it turns off @ redline and than back on after the ****t @ like 4k or wherever the autotranny puts it? will this on off put 2 much stress on the tranny/engine? im going 2 be runnning a 75 shot

 

I think any shot of nitrous in any situation on an auto is going to be too much stress for it. It's a lot more delicate and it's going to really hate those sudden jolts of power. If you do use nitrous then you will definitely want a GIANT tranny cooler. I have a felling that you'll kill your pressure plate quite soon. You'd probably get away with it for a couple of shots but you'll start chippin' little pieces of metal of your gears. I would suggest to get a manual in that before you juice it if you've got the resources. I hope this might help you out.

 

Pressure plate what pressue plate its an auto

Any how i ran the zex kit on my auto for about
two years and i used it quite frequent
(refill every two weeks)

about 1 year on 55 shot then upped to a 65 shot for a year
then i did a tranny swap and the auto was and is still fine i even took a look at the tranny filter after i took it out and it was clean no metal

yes i did have a tranny cooler and changed the tranny fluid twice a year begining of summer and end of summer
i also had a nitrous controller wich i set to stop flow during shifts

a 75 shot would shorten the life as any shot will
and take note that with a hyundai auto
there's about a 50/50 ratio of good and weak auto trans

 

how big of a tranny cooler should i get

 

well i went for the biggest i could find
and i went for a multipass cooler instead of a
tubular cooler as there not as efective

on an auto heat is a killer for them as it burn
the tranny fluid

 

Sorry...I meant torque converter (really tired when I wrote that)

 

i have a b&m tranny cooler. i used to run zex on my car.
ran a 55 shot for a while then up'd it to 65 shot. loved it. id spray while the gears changed. never hit the redline.

just take care of the tranny.
