Sup , i have an build 4.3L V6 that i'm gonna put 175 shot (NX) thrue it . I have an YANK nitrous V6 converter ( 2500 stall ) but i can only brake stall it at only 2000-2100 rpm . I have ET streets and i want to launch with all that shot . I know lots of you guys would tell me not to spray below 3000 rpm but if i wait until it reach 3000 rpm it may bog or or something . IT doesn't have much power like you guys with V8 . So i have seen you guys talking about flashing the converter with the nitrous . So how do i do it ? The full shot would be under 3000 rpm for a split sec so do you guys think it will damage the motor in that split sec with that much cyl presure ? I have an 350 ramjet intake cutted to fit my 4.3L , so what do you guys think of this intake for an big wet shot in it and would there be fuel pudling problem ?
thanx

 

Some may disagree w/ me on this, but I think you'll be OK if you launch on the spray at the 2100. When you hit the spray, the effective stall speed is going to jump up anyways directly to ~2500 or so.

I'm not a Yank/Vigilante expert, but most places rate their converters by true stall. and so you'd be about right getting ~2100 on the footbrake out of a 2500 stall converter.

Good luck!

 

Thanx man .
Actualy Mike from yank told me it would be an 3000 stall but i could only flash it at 2500 rpm and brake stall at 2100 rpm . I tougth that if i hit the 175 shot at around 2100 rpm it would flash to somewhere 3500 rpm or more . I want to know what do guys that have stock converter mean at shooting nitrous off the line . Cause i think the stall is around 1600 rpm . I read some post in here about shooting nitrous at low rpm but most the you guys says never to spray below 3000 rpm and thats starts scarying me .
c-ya

 

In the Cam/Birds that mostly hang out here, the stall is around 2100rpms on a stockish engine. It can be foot brakesd o ~1600rpms.

What I was getting at before is that with your slightly higher stall, when you engage the system it will flash up to 2500 or higher almost immediately, taking you right out of that dangerour point in which some guys deem to low of an RPM.

 

Thanx man , thats the answer i was looking for .
