Nos ?

[Colorado Scott]

why would you want to use NOS, I mean shit, my 04 cranks out 217hp and that does not include the acetone. What do you want next, Banks twin super charger from a diesel are something.

Ooooh 217hp? Acetone doesn't do jack for HP or torque. Suckers? You must be a flat-lander.

For pulling long highway hills I say go for it. I want one too! I tow a 4,800 pound trailer and I would love to be rollin? at 60mph up and through the Eisenhower tunnel and over Vail Pass instead of struggling at 40mph.

Nitrous requires more than just a bottle and jet to work properly too. Those kits with nothing but a switch and a solenoid are garbage. Luckily, the people who don't know how to use it or go cheap get blown up fairly quickly- kinda like a Darwin thing.
I've used it a lot over the years and never had a problem, so it CAN be done. It's just not a quick OR cheap fix if done right.

Yes, it can be done if done correctly. But why? Like I said before in an earlier post, a 75 shot would probably be the safest on a Rover engine. I have experience with nitrous-powered cars and can tell you that a 75 shot or even a 100 shot is not gonna give the Rover that "kick in the ass" feel. I had NOS in a stock 5.0 Mustang and didn't really "feel" any difference 'til I bumped the jets to a 150 shot.
jdcline78, if you want to install NOS on your Rover, do it. I just think it will be a waste of time and money. Just my $.02.

I still say do it!!!!!!!!!

Did I mention I have some sort blocks for sale?

 

[logigeek]

Do it!!!!!!!!!!!!!!!!!!

How many bottles do you plan on installing? Do you want to have a nitrous bill to go with your gas bill? You do have to re-charge these things, you know... It's usless as soon as you run out.

Contrast that with a mild cam and a reasonable supercharger, plus a re-worked air system, and a PROPERLY designed exhaust system. Get handy with a Dremel in the manifolds, and things get better. That's at least 50 HP from the getgo, CONSTANT. With little reliability lost. If you can chip it at the same time, even better. Have it professionally re-mapped after the install, and you are sitting extremely pretty.

Hell. Stock RV8s seem to absolutely love a twin turbo setup.

Nitrous is as silly for street use as it is for wheeling, especially on a heavy truck that will take a while to get up to speed even with another 50-100 HP. It's a waste of an energy source that has a limited supply. You need something that makes the motor a better air pump.

try changing your gear ratio

 

[D Chapman]

Kennith,
Tell me about these supercharged and Twin Turbo charged rovers. Have you ever seen one? Who has one? How many miles are on it?
I call BS on the reliability.

Nitrous doesn't work like the Fast and Furious movies that all you guys claim you've never watched, but I bet the DVD's are hidden under the bed. It's not as if you punch a button and a surge of power slams the drive line within a fraction of a second, jerking your head back into your fake eBay Sparco copy seats.
Lots of people outside the Rover world have used nitrous for towing and it works. There are progressive controllers that ease it on and watch for detonation. A good system will keep the timing from advancing- that's when things explode. Unfortunately if you plan to rely heavily on nitrous for power, the adjustments you have to make to run big shots of it will reduce your HP when not running it... except if you go high end and drop $2K on a proper system. Back before these processor controlled brain boxes, we used to have a series of relays and solenoids that were connected to a boost gauge (we were using nitrous to correct bad turbo lag), and as the car made boost it would back off the nitrous. At full bore, I was running a 250 shot on a Nissan 300ZX and it would taper down to zero at full boost. That car laid down 670HP at the wheels- back before it was a common thing on an import car. That car is still around, although the nitrous was removed and smaller turbos fitted and has almost 200K miles on it.
As for the Rover V8- I've seen TVR guys doing crazy stuff to them and having fun.

 

[kennith]

I've seen quite a few. Most not in America, though I am sure more exist here. One Range Rover had over 200,000 miles on it and was used for scavenger hunt type rallyes quite often. I think it had about 100k with the actual turbo setup. It was a 1989. I have seen a few more, but most of them were older. A DII was used as well, but it had a bit more done to it, and I have seen a few D1s. Then there are your drag cars using forced induction on a RV8, quite a few of those. A couple of Nissan pickups with them shoved in the engine bay just for car shows had small turbos. There is that Defender in the US or was it Aus? I think he had problems with his setup, though.

And I know nitrous can be used in that manner, I just don't think it's the best solution. I also severely doubted that was what he meant. It can get almost as expensive as the things I mentioned in the long run.

It's like anything else in that respect. Extra stuff with a benefit you have to constantly pay for. I'd rather have the motor use more gasoline, and only have one fuel to worry about. I did toy several times with the idea of using nitrous in my Discovery, just to be a little different, and all times I really couldn't put it up beside forced induction, or a good old fashioned stroke and big cam, and seem myself on top. Either way, it ends up a gimmick that you have to pour money into.

Maby I jumped the gun on them, but you have to admit, when somebody mentions throwing NOS to a car, the first thing that pops into mind is some yahoo that has played too many videogames.

Cheers,

Kennith

Forced induction can work on them- but the people who believe everything RPI says can't admit it, but there's a story there. RPI blew up a ton of engines and screwed a lot of people when trying forced induction, so now they claim it cannot be done and have quite a diatribe on their web site about it. The thing is, the blown up failed attempts were their own! They just won't admit it.
There was a kit back in the late 80's that worked really well using a sprintex compressor and a piggyback ECU. It was over $6K for the kit, so only the beautiful people could afford them, but they really woke up the ol Rangies.

So, your telling me in 20 years, no one has made another kit to bolt on to a fuel injected Rover? I wonder why......

RPi was not the only ones having troubles.

Can it be done? Sure. Will it last? No Is is even worth fucking with? Hell No

 

[edthediscoman]

Nitrous Got me airborne.....naaaa...I just farted!

 

[jdcline78]

Eaton super chagers makes a bolt on carger for about $1000 that ads 80 to 100 hp Ive seen it and I missed buying the range rover p38 that had it equipt by one day I drove this truck and you can deffenitly feel the difference I AM ALREADY GEARED WITH 4.75'S and the only driveline change I haven't done is a atlas 2 tcase witch I am saving up for now

Let me know when you find that Atlas.

The kits were $6K... that's why. The serpentine belts that came along made a redesign necesary and then the newer computers were harder to work with. Nobody makes them now because who would buy a supercharger for a $1500 truck? RPI wrecked the entire idea of supercharging a Rover, although others successfully did it.

 

[D Chapman]

Sorry Steve, the tolerances in these motors are worse than a Harley Davidson. Without extensive machine work, it's not going to last. The only thing worth a shit in modern Rover V8's is the crank.

If your caberating this supercharged engine, it may work. Otherwise, it's not going to happen and last. The 3.5 or 3.9 would be the best bet, but even then, your on borrowed time if you run it at higher RPM's often.

 

[MUSKYMAN]

well back in the day of the buick 215 the hot rodders were bolting a offenhauser manifold and a roots style GMC 471 blower on top of these engines and making big power.

but they milled the tops off the pistons,starped the main caps and ran chevy valve springs to make it all work right.

IMHO any time you are dealing with either forced induction or Nos you need to start inside the block or its a very short term deal

but then again a dry 50hp shot may be just what a 4.0 needs to keep the carbon off the valves.

 

[D Chapman]

Back in the day, those guys were running a 300 crank and a set of 300 cast heads totally reworked, too.

You can pull some major HP out of these engines...just not with the Rover FI.

all you have to do is call advanced adaptors the cost is around $2400

So, how is the drive shaft going to mount? The only way it would even come close to fitting, is if it were turned upside down... Even then, the rear shaft would be at an angle.
