Has anyone dropped in a nitrious system yet for these new 4.0 stangs? if so what can they handle? and what type of hp are u getting? also what type of system?

Not saying I plan on spraying but keeping my options open. I would rather mac dual exhaust , and then supercharge down the road. Just want to get a feel for what people have done to their 4.0's and how far can we stretch them before they break with just factory engine.

I was running a 25 shot for a while, but didn't want to go over that until I was able to have the car tuned / colder plugs were available.

I removed the system, when I took it back to the dealer for a free oil change. I was going to put it back on, but I really want a bigger shot (50-75 range), and for that I need a custom tune and colder plugs.

From what I've read the stock internals should be ok up to about a 75 shot, maybe a 100 with a REALLY good tune. I wouldn't go over that until you've rebuilt the engine with stronger internals.

You're gonna run into the same problems with a charger. The engine as is, can only take about a %50 increase before it fails.

You also want to be careful if you remove the rev limiter. I hear the crankshaft tends to flex all outta whack at high RPM's in the 4.0 engine.

wow that is it 100 more HP???? geez that kinda sucks do we know for sure that is all the stock engine can handle? I imagine that ATI will charge close to the max on whatever the limit is. Thanks for the info... I guess no since in adding nitro........ thanks for the response
