I want NOS on my disco. I was thinking about putting a single nozzle behind the MAF on the hose or maybe tapping the intake and just trying it. Anyone given it a shot (pun intended). The stock 4.0 has a good bottom end, runs overly rich and with the knock sensors and everything it should be ok, besides new blocks are cheap  Ron PS I know its not a race vehicle but I really like going fast. stock it will do 60mph in 8.8, I would like to see 7 seconds. | ||

interesting....I want to see this. | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 210 Registered: 11-2002 |
NOS ROCKS!!! but if i was gonna do it I would use a jacobs NOS controller to integrate the knock sensor with the system to prevent a fry down. that or just limit the size of the jets,but then 0-60 in 7 seconds would be real tough. | ||
| Ron Brown (Ron) Member Username: Ron Post Number: 168 Registered: 04-2001 |
1.8 seconds is not much, what size jet would you recommend? I was thinking about getting a 60hp or 80hp shot. Whats this whole jacobs thing? I am getting my new Y-pipe tomorrow and I am thinking about getting a borla to so that should get me a couple more horses. Ron | ||

NOS is rough on an engine. Take it from someone who has played with it before. I have done some work on my 4.0, including machine work to the heads and port matching. I can edge out a 4.6, and that's with stock cam and computer chip, no NOS. If you spend a little time and choose your components carefully, you can probably get what your looking for out of that engine, without the danger of grenading it. And spend less than having to buy a new motor. If you do NOS, don't forget to ice the bottle down everytime you go to fill it. Just an old racer's trick. | ||

Here Ron: http://www.crutchfield.com/S-rD67LzEbLUW/cgi-bin/ProdView.asp?i=204NOS8 All the poseur benefits of NOS and you will be upgrading the crappy stock sub Oh yeah, adding the 'NOS' sticker to the back window will lead to even more performance increase out of this system..... | ||

NOS is really not hard on an engine thats in decent shape. It will more then likely kill one that isnt because it just agrevates issues already present. Ron ? You shure you want to do that ? I have a 250 horse kit sitting in the garage somewhere.... Getting the time increase you are talking about aint nothing but a thing as far as power is concerned. The driveline however might think differently. As long is you keep it rich you wont have issue. Tap the upper plennum right behind the Throttle body and let the big dog eat... I wouldnt touch the button from a dead stop though..... Thats gonna be ugly..... Kyle "Blow me" | ||

Kyle, Excuse my input, but: "I can't believe KVT wants NOS...isn't he the one that prefers Detroits over ARBs for their simplicity???" Just my input... | ||

NOS kicks ass! This is coming from someone that burned a perfectly good Chevy LT-1 with the juice. I cant wait for my next NOS car. There is nothing else like it. Next time..... Ron, might as well just order that new short block at the same time as the NOS kit. You'll need it. Dont bother tapping the manifold, just put a jet in the rubber tube just ahead of the trotle body. Hell, if your gonna do it just go all out. Do a 100hp first stage and a 75 second. You'll probably put 350hp to the ground through all four. At the light, hold it on the brake as high as the converter will allow. Drop the brake and floor the gas all at once, hit the first kit. Four wheel burnout. Wait a moment till it hooks up and hit the second kit. Cirp the tires again and off you go. You will do a bottom 14 or top 13 in the quarter. About 2 times! After that start working on putting the new short block in. Transmission, axles, drive shafts as neccesary. A stock disco does 0-60 in 8.8? Since when? I would be totaly surprised if my 98 would break into the 11's (0-60 not quarter mile, how sad). As master chung would say, JUST DO IT! Dan | ||

lol , it really cracks me up to see and hear the horror stories of the people that grenaded shit with the jug. Although , just reading the post tells me what kinda guy was behind it..lol Nadim , you still fucking up. I am not vouching for it , I am simply telling fact on it. I have used it more then plenty and before pulse solonoids came out and timing computers and all that jazz. Its not that hard on a motor that is in decent shape. Its simply isnt !! If the motor has some issues it will certainly bring them right to the top. Or if you dont know what you are doing with the shit. You need to get that timing back and keep the fuel rich. You do that and you are in good shape... Do any of you know where NOS was first used ? And if you know then you also know it wouldnt have been if it grenaded every motor it was put on... All I am reading here is "Urban legend"...... Kyle "Blow me" | ||

| Jason T. Barker (Speedminded) Member Username: Speedminded Post Number: 134 Registered: 10-2002 |
It also has alot to do with how you use it. Most people are always running cars much harder while on it....constant redline, wide open all the time, etc. Even running like that without the nitrous something is gonna give eventually but the nitrous just adds to it. Would "Adds fuel to the fire" be a pun or a cliché in this case? Its just cheap, easy, & addictive power. | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 211 Registered: 11-2002 |
i have run nos on three cars...one old base plate 4barrel kit and two in modern injected cars. one my BMW. never fried anything ever! once again its all in the set up, just like most mods you have to be smart about what you are doing. in the BMW I used a jacobs NOS mastermind system that would retard the spark as the NOS came on. that way you could still have maximum power when off the bottle and retard and protect the motor when you are pounding it on the bottle. I agree with Kyle I would avoid launching it on the bottle only bad things will result.the driveline just isnt meant for that, but with a well thought out system you could blast and blast away with out problems in a healthy rover motor.or any healthy motor for that matter. hell people run 300hp systems on old honda motors, A rover could sure use 100hp squirt thom | ||
| Brian Friend (Brianfriend) Senior Member Username: Brianfriend Post Number: 552 Registered: 09-2002 |
My big question is what would you do with that power? The thing still will not be fast right, except when the nos is used. And how long does one shot of it last? Off road uses? | ||
| D. Chapman (1hank1) Member Username: 1hank1 Post Number: 72 Registered: 02-2003 |
Do you really think the 24 spline axles will handle a 100hp shot off the line? | ||
| Greg Hirst (Gregh) Member Username: Gregh Post Number: 124 Registered: 10-2002 |
Yeah, for aircraft it was an even more dramatic improvement due to normally decreased performance at high altitude. The Germans also pioneered water/methanol injection in same aircraft for same reasons. I've read of experimental supercharged/nitrous ME-109's even but don't know how they faired. I really don't understand the attraction of nitrous in a Rover though. Maybe in a TR8, MGBV8 or even a 3500 but in a Land Rover? Give me a big broad torque curve and tires and gearing. (and lockers, articulation, clearance,etc.) | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 212 Registered: 11-2002 |
till you let off the button no reason for it in a disco but I know lots of guys that run 44" tires and NOS in the mud. one guy I know touches the button to blast the mud out of his treads during long continued mud bogs....but he is a sick fucker that puts 600hp in 4000lb trucks | ||
| Greg Hirst (Gregh) Member Username: Gregh Post Number: 125 Registered: 10-2002 |
Yeah, I know the kind. One guy I know in Norcal runs an FJ80 with a twin turboed Chevy 350. He runs front/rear Dana 60's with custom coil suspension and has more money than sense. (Maybe I'm jealous? Of the money that is..) | ||
| Christopher Dynak (Adtoolco) Member Username: Adtoolco Post Number: 120 Registered: 08-2002 |
After reading this thread all I can say is: Why haven't I done it yet? The Disco could use a good kick in the ass. The only question I have is how to integrate it into the ECU? Does the Jacobs system do this for you? -Chris | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 213 Registered: 11-2002 |
sorta...it uses the knock sensor output to retard the spark and shorten the pulse duration. the real benifit comes from controling the NOS in a number of ways. Nos at too low of rpm will do big damage to blocks bendind rods and inverting the dome on pistons and cracking brittle cranks. the jacobs system integrats the NOS based on rpm. the more the rpm the more NOS a motor can handle, thats why those little rice grinders take it so well. also if fuel pressure wimps out such as it would with a wimpy land rover fuel pump you need to be able to turn off the bottle in a milisecond or you will fry holes in the pistons. the jacobs system controls the bottle and shuts it down if fuel rail pressure drops. The jacobs system also has a pulse duration control that lets you tailor the amount of NOS so you can prevent blasting away and losing traction . losing traction will lose you tons of time coming out of the hole. all in all it will let you use NOS in a very safe way preventing all the bad aspects from biting you in the ass. thom | ||
| Kyle Van Tassel (Kyle) Moderator Username: Kyle Post Number: 142 Registered: 11-2002 |
Thre is definately no use for it in a disco and after using it for awhile you have issues. Not the truck , YOU ! The poor ole truck will never feel the same again.... Thom , when I was still in high school we did a couple of mud runners with power shot kits on them. It was actually kinda fun in a sick sorta way....lol Kyle "Blow me" | ||

| Christopher Dynak (Adtoolco) Member Username: Adtoolco Post Number: 121 Registered: 08-2002 |
So Kyle, Just curious. How did you "get off the bottle"? Anyway, I wouldn't add it until I port & polish my heads & intake and switch to a 4.6 crank, rods, pistons, etc. With all that said, the bottle is REALLY attractive. | ||
| Kyle Van Tassel (Kyle) Moderator Username: Kyle Post Number: 143 Registered: 11-2002 |
I got off using the bottle all the time by going from 351 cubic inches to 428 cubic inches...Although , I was primarily a street racer so the darn thing somehow stayed in the car even after the swap... Just got harder to see... For comparison sake , I had 1.5 60 foots with the fairly "Stock" 351 spraying it right in the gate. After the swap to the (Not so stock) 28 I had some 1.45s but was mainly still in the 1.5 range and no jug. So you can see that the little blue man does make up for some horses.. Couldnt spray the 28 in the street as it would just blow the tires off the car even with the glue on them.... Its a violent thing when you push that button right from jump......lol Kyle "Blow me" | ||

LOL I love it. Oh well we will see, how would you wire it. Full throttle kit and a switch was all I was thinking and possibly an adjustable fuel pressure regulator. Its just a little baby kit out of a 4 banger. I like the four wheel burnout thing. I know the cvs hate it but there is nothing like seeing all four spinning 911 turbo style. Ron PS 8.8 to 60mph is for a 5 speed disco | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 220 Registered: 11-2002 |
I agree 4 wheel burnouts rule. everytime I smoke all 4 on my trail truck on the street whoever is next to me freaks out and stops racing. so it is pretty cool. superchargers are way more complicated and demanding than than NOS and Superchargers heat the intake stream where NOS super cools it so if I was looking for a once and awhile blast of power on a disco Nos would get the nod way before a supercharger would. | ||

So Thom how would you set it up? Ron | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 222 Registered: 11-2002 |
i would add a second fuel pump use the jacobs NOS mastermind and two fogger jets in oposite ends of the intake plenum. run it with a two stage set up that dumps 50 hp or so on stage 1 and and about 125 hp after the motor is turning 3500 rpm or so. | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 223 Registered: 11-2002 |
if you were going to use such a aggresive system you would want to use a wet system that injects both fuel and NOS. if you could satisfy your thrill with 60hp or so(still wont get you to 60mph in 7 sec) then you could go with a dry NOS injection sytem and rely on a variable regulator to boost fuel rail pressure to suplement fuel, but be warned that type system is sloppy and needs to be watched close. | ||
| Carl D. (Cdoug3) Member Username: Cdoug3 Post Number: 42 Registered: 01-2003 |
I tend to disagree on the nos vs supercharger thing. A supercharger woudl be better suited for the land rover engine and the way that it is used than nos. Also the supercharger may heat the intake air but that can easily managed. Superchargers are more complex than a nos system but as a whole it is less stress on the engine and drivetrain parts. The supercharger would also yield better gas mileage as a whole. As a side note: Before I sheared the teeth off of first gear I would get crazy looks from doing 4 wheel burnouts in my Audi although I don't think I would want to be pushing the button of that bomb on the disco. | ||
| Greg Hirst (Gregh) Member Username: Gregh Post Number: 130 Registered: 10-2002 |
For anyone interested spoke with a friend from Chino Airport about supercharged/nitrous ME-109 and he said it was relatively common in use at end of war. FWIW I looked and found this about DB605 engine: http://w1.1861.telia.com/~u186104874/db605.htm | ||
| Kyle Van Tassel (Kyle) Moderator Username: Kyle Post Number: 144 Registered: 11-2002 |
Yeah Greag , I laugh my ass off at the thought of those boys yelling (In german) "Spray this bitch!!" lol Carl , well , I hate to break it to ya but the charger and the NOS do pretty much the same thing, just in different ways. Ron those baby kits arent real hot and are mostly dry systems. Dry systems are bad bad bad unless you can richen the motor through other means. Just keep in mind that the NOS is not a flamable substance. It allows the engine to burn more fuel thus increasing the flow going through it. If there isnt more fuel added then you arent getting the power gains from it and you are running serious risk of detonation and just generally fucking up your junk. I have seen quite a few instances of this and its not pretty at all. This is where all the NOS horror stories come from. I aint sure the Disco would handle a 4 wheel burn out at all...lol Thats gonna be real ugly.. Kyle "Blow me" | ||

I wont get into the theory of it but depending how you set up the systems, the nos actually creates for stress on the engine components. Once again depending on how you have it setup. | ||

LOL I was mostly joking in my post up above. Sure 4 wheel burnouts are cool, but not in the disco, unless your related to Bill at GBR. There really is nothing like NOS. Between a supercharger, a turbo and a NOS kit that all add 100hp the juice will feel the fastest of the three. I'm making plans for my 2 stage system now. But this will go in an LS-1 camaro not in the disco. I was mud bogging the disco Friday afternoon and she seemed to do fine with the stock 4.0 in low locked. I know my pig is slow but in off road situations at under 20mph in low she does fine. I think the Rover people knew this when they put that 4 liter in there. I for one have never wanted to add hp to the disco. If I want to go fast I'll get a car that's fast to begin with (chevy LS-1) spend 2-3K and do solid 11's. Why spend money on the rover so I could do 16's instead of 18's? All that said, four wheel NOS burnouts still rule. Dan | ||

Oh boy. I leave for a week, and Ron posts this while I'm not looking. Please don't encourage him... he drives too fast as it is! And yes, he absolutely accomplishes four wheel burnouts. Like a moron. At stop lights. In the rain. I prefer driving under the speed limit. |
