I recently purchased a 78 chevy malibu for 600$. the car is super solid (for ohio) and has a 74 350 in it that was rebuilt to stock. The car is a super gradma cruiser with its stock hub caps, white walls, two-tone paint (tan and copper.....puke!), and the landau top. I've been driving it every day and recently cut a 14.8 and the strip in it (with single exhaust, a cat, and 2:29's in the back). I'm thinking of installing a nitrous shot on it to just blow some minds with. I need some good tips on about how much I can spray and completely hidding the system.

I wouldn't worry about hiding the system, but on a stock motor with no timing retard and a stock fuel system your gonna want to keep it way down, like 50-75 Hp. Something that may be beneficial to you is looking at a lower rear end gear ratio as well (and a posi if it isn't one)

I agree with gib here.  I would get some gears in the back, at least 3.42 or 3.73's.  I would also do something about that exhaust before I thought about nitrous.  With what you have now your not going to blow many minds,  you may just blow a headgasket instead.......

Obviously you guys have not run much nitrous-


You should be able to use 75 to 150 shot on premuim fuel with no problems and no changes in timing, exhuast, gear ratio or anything and it should run real good. If you live in a cold area be sure to get an electric bottle warmer and a nitrous pressure gauge and run the bottle preasure between 900lbs and 1100lbs.

QUESTION Can I simply bolt a nitrous kit onto my stock engine?

ANSWER Yes. NOS manufactures systems for virtually any stock engine application. The key is to choose the correct kit for a given application; i.e., 4 cyl. engines normally allow an extra 40- 60 HP, 6 cyl. engines usually work great between 75-100 extra HP, small block V8’s (302/350/400cid) can typically accept up to 140 extra HP, and big block V8’s (427-454) might accept from 125-200 extra HP. These suggested ranges provide maximum reliability from most stock engines using cast pistons and cast crank with few or no engine modifications.

 

QUESTION Will nitrous oxide cause detonation?

ANSWER Not directly. Detonation is the result of too little fuel present during combustion (lean) or too low of an octane of fuel. Too much ignition advance also causes detonation. In general, most of our kits engineered for stock type engines will work well with premium type fuels and minimal decreases of ignition timing. In racing application where higher compression ratios are used, resulting in higher cylinder pressures, a higher fuel octane must be used as well as more ignition retard

 



QUESTION Are there any benefits to chilling the nitrous bottle?

ANSWER No. Chilling the bottle lowers the pressure dramatically and will also lower the flow rate of the nitrous causing a fuel rich condition and reducing power. On cold evenings you might run on the rich side. For optimal running conditions, keep bottle pressure at approximately 900-950 psi. NOS has a nitrous pressure guage that allows you to monitor this. If you live or operate a nitrous system in colder temperatures, it may also be a good idea to purchase a bottle heater kit, part #14164. Generally, ambient temperatures of 80-90 degrees Fahrenheit will allow for best power potential of NOS kits.



QUESTION Will the percentage of performance increase be the same in a highly modified engine compared to a stock engine when using the same NOS kit and jetting?

ANSWER Not really. In most cases the percentage of increase is greater from a stock engine because it is not as efficient as the modified engine in a normal non-nitrous mode. However, since the effects of nitrous oxide magnify the output of any engine, the total power output will be much higher in the modified engine.

 



QUESTION Should I modify my fuel system to use nitrous oxide?

ANSWER Most stock fuel pumps will work adequately for smaller nitrous applications. It is important to check to see if your pump can flow enough fuel to your existing fuel system (whether carburetor or fuel injected), as well as being able to supply the additional fuel required by the nitrous kit under full throttle conditions. It may be a good idea to dedicate a separate fuel pump to the nitrous kit.

It's a real shame, I thought by now you would've left. You really think it will run just great with those 2. something gears turning 3000 RPMs at the traps and frying one tire off the line, alright whatever... I'm just hoping everyone just ignores your advice.

Well, you booger eating moron, he ask for advice on nitrous and since you know very little on the subject other than what you read rather than from first hand experience, you tell him to do other things than what he ask for. So if I want to change my carb, should I look at changing my rear end gears first? Dipchit! Nitrous makes a ton of torque, you could run 2:29's and still run good and be a driver also. We have run open 3.08 with good results on stock street cars sleepers. Why don't you try it first before you shoot off your advice. And how do you know it will benefit him if you don't even know what he is doing nor how much he has to spend? All he asked was "I'm thinking of installing a nitrous shot on it to just blow some minds with. I need some good tips on about how much I can spray and completely hidding the system" and you tell him:

Listen sphincter, gibs does know what he's talking about. Now, unless you are going to switch to a forged piston, stick to 100hp shot or less, for reliability sake. if you want to hide it, use a top shot system, and sheath the lines in rubber hose.

I've used nitrous on many vehicles, using many differing styles of systems, and I've about had enough of listening to your book smart ass. You say all he knows is what he's read...you don't even know who he is.

Those gearswill work, but you'll be comprimising alot.
Shows how much you know, ***

I remember way back in the eightys peoply were running nitrous and blowing pistons out the tail pipes. keep it low. even a 75 shot may be the end of your daily driver.

On a stockish, cast piston motor, I'd go no bigger than say 100hp. Most of the time, people blow stockish motors on nitrous because they run it too lean, or don't have any idea how to tune it, or just try to run too much nitrous thru it.

Hello,


 


Sheesh!!! What a mouth full. Though the guys are right about keeping the shot around 100 or so, just make sure the fuel pressure is up to snuff at wot, you don't wnat to go lean ( cooks the pistons, not good).


As for the rear end, if it's an open diff, then you will more than likely just spin the hell out of it, looks cool but doesn't help ET or trap speed, still it is fun. I would be careful using the juice on the streets though, with that rear diff, hitting nitrous at low rpm can stress the bottom end pretty hard not mention the drive train. I'm speaking from a little experience in this matter cause my buddy had basically the same set up and it worked twice then new noises were heard that weren't there before, though it was with a bit more juice than 100. oh and I'd back off the timing 2-4 degrees and make sure the plugs are fresh.

thanks for all the info guys. Recently installed a buddies plate system just to see what the car would do. The system is on the car and jetted for 125hp and the motor takes it all day long (surprising). Although after 5 test runs on a industrial road outside town it destroyed the the carrier in the 7.5. it does now have a 72 skylark 8.5 with a posi and 2.73's which my still sound lame to most but really stepped this car up. when I get to the strip i'll let u know.

Your car sounds like fun.  That 8.5 should take some abuse.  Should also be a non c-clip.  Spend a little and put a ring and pinion in it, bro.  It would be a lot more fun.  Good luck!

went to the strip yesterday (dragway 42), i bolted up the M/T ET radials off my nova on it and got it to go 13.2 as a best. kinda good for a stock motor (smog motor at that). i think i'm gonna put a old performer intake and cam package on it i got in the garage and and maybe pill it up to 150hp and see what happens.

Just messin with ya.  Sounds like fun.  Good luck

I love the smell of burning rubber in the morning
