You're going to laugh, but NOS w/ a progressive controller may be the easy fix here. The part about NOS that blows up engines is the sudden shot of XXX hp. A progressive controller allows you to dial in the amount of power, and over what duration. So you could select a moderate 50 hp that gets delivered over 30 seconds...enough to get you accelerating up that hill. It's about $750 for the entire set up and requires little else, and works just as well on lower rpm engines.

Accepting spears now.

i wouldnt lol gotta keep a bottle warmer on if you want the correct pressure, then there is too much pressure- also this is what happens when you pill up

Hmmmm
Researching. I've never messed with the stuff. Is it feasible to think that smaller gains would be reliably consistent? And Can I incorporate a switch into my hula girl?

And that looks pretty rough, lsJuan. What vehicle?

That was the second motor in the GTO when i had it.
I would stay away, seen a 416 and a 447 stroker eat bearings cause of it, even being built as nitrous motors.

plus once it runs out you are still on a nitorus tune and it will lose power off it.

I doubt a 50 shot of NOS would require a tune, or would pose much danger. All your horror stories are minus a progressive controller. However, if it' still idiotic (I've never tried in this application), please reference title of thread.

nope. that would be a progressive controller, this kit was on the 416 and 447 before it was on mine- though i will admit it was way more than a 50.

I ran a 2.0 Ford Cosworth BDA on nitrous/methanol back in the 70's/80's. It was a bit unstable and the problem was that it required flushing out with petrol after every race otherwise it eat away the alloys and magnesium parts. It was great for extracting the final ounces of power but needed setting up properly to run on the stuff as a naturally aspirated engine running on Webber carbs with electronic ignition back then caused many other headaches. I can imagine it's even worse on injection.

The worst point was the safety aspect, you couldn't see it burn and even worse the marshals couldn't see it alight so you had to have special decals declaring you ran nitrous/methanol and carry an automatic water deluge system onboard or get cooked alive. Many historical cars today, hybrids, still use it along with superchargers.

That does sound like fun. Invisible flames and corroded engine internals. You can run around the track in your underwear like Ricky Bobby.

All nitrous does is give you more oxygen to burn more fuel. The problem with trying to add power with it as I understand it is that the nitrous and the additional fuel needs to be added very uniformly in order to avoid disaster. If you are running a full on race motor and you can dump in lots of nitrous and lots of fuel into a manifold that has a large volume of air flowing at high velocity then it gets pretty well distributed but to add a small amount of nitrous and fuel into a motor operating at part throttle you won't necessarily get the same positive outcome.

Maybe a nice direct port system: Nitrous Systems - Direct Port Nitrous Systems - Edelbrock, LLC.
You could plumb it in below the manifold in the valley. Add some higher flow injectors and then watch the check engine light do its thing while the driveline tears itself apart.

I really have to wonder just what is going on with the engine you have. I have a 4.6 in mine with stock gears and 32 inch tires and I'm never feeling like I need more power. For what it is, my truck does just fine. I'd be willing to bet that a 4.6 with a cam that isn't worn out would be sufficient for your needs. Not to say I'm not anxious to see how all your proposed improvements work out but I wouldn't look to build something that is on the verge of blowing up all of the time.

A 4.6 with a decent valve job, port and polish, extrude hone of the manifolds (Extrude Honing | Powder Coating, Ceramic Coating and Abrasive Blasting Specialists), properly cleaned and operating fuel injectors, headers possibly, higher flow cats and mufflers, your bigger cam and rhoads lifters should make for a reliable, capable engine. With that setup you should be able to get yourself thoroughly mired in a Texas mud hole at some Rover event.
