How did nitrous get such a bad rep...?

Please tell me this isn't the ultimate answer to why nitrous has such a bad stigma as compared to turbos or supercharging or ProChargers?
With your vast drag racing experience I know you have more to add...

I'm trying to blast on anybodys stuff either.. instead of counting how many times you said "if" or "needed" and totally for discussion... I think it would be agreed that if you have more to lose and your conscious of it that you would take more precautions.. also if you had an unrealistic view of your self-control (which I don't) it would be easy to take less precautions... I could see one of these basic kits and a low budget or junkyard motor and going for it being a suitable match.. on the other hand someone with a little bit of coin into their engine might consider a few extra precautions?...

Quite the contrary, if I understand that correctly. Trying to stay on the topic of nitrous getting a bad reputation, I believe most of what the naysayers come up with has been debunked by my car, in my experience, and in my opinion. I have added the same basic setup to another car with much more to lose if I screw it up, and we'll see what it does at some point (haven't yet), but I am not worried at all because I now know, only from my own experience, that it is much more forgiving at these lower power levels than the stigma leads people to believe.
Just look at how many times in this thread alone people have repeated the same old stuff, about it will blow up if you don't do this or that, or have this or that.

Maybe the better reputation for turbos and superchargers comes from the late 80s and early 90s cars really getting into those. But remember, those were usually fuel injected and kits come with a tune that is also on the safe side, and there is not much the average Joe could go into and screw up since it required professional tuning. That leads to less failures, and of course nitrous never got past the greedy users that burned up their stuff with bad tunes and lied about it being a solenoid failure, or better yet, just what happens when you use nitrous. Lol.

I found with my experience that dual quads have limited power adder availability... of course unless you're ready to sell the house or get a mortgage to buy a routes style supercharger... Never seen a dual quad pro charger or turbo setup yet.. not saying it can't be done..

Mike and Dale filled hundreds of bottles for us when they were in Signal Hill and Cypress. Used to hit up ol Marvin in Whittier to when in a pinch in that part of town. Lazar was up there too. Back when it was around $10 to fill a bottle IIRC.

It's funny how we have a whole section on the forum for forced induction conversation, but none for the redheaded stepchild nitrous...:mob:...:rolleyes:...
Look how many people use it without having a place to discuss it...

I was well on my way to building a dual throttle body turbo setup on my Honda engine. I built my own aluminum intake and joined the throttle bodies with a common shaft and had it running. The plumbing was just too much of a mess to make it look good. I went a different route. A single larger throttle body with boost can support way more hp than I plan on making with this engine.

That's why I kind of left it open.. I wasn't saying it was impossible, but you'd have to have a lot of will and a lot of way...
 
I forget the guys name but there is someone on FABO that helped a friend build a twin turbo twin carb 318 (?) in a truck. I’ll see if I can find the thread.

Some valid points, but some I believe are exaggerated. Let's say I agree with all the precautionary extras on a serious use with big horsepower gains. then we can move onto why I don't run all those extra parts that add cost.

First, a pressure gauge on the bottle fitting tells you pressure only. Does nothing for bottle liquid content, which is only accurately measured in weight. A 10 pound bottle carries 10 pounds of liquid nitrous. That same bottle that is 5 pounds light is about half full. Also, generally speaking, nitrous bottle pressure will be about 10psi for every 1 degree of fahrenheit of bottle temperature. So a 90 degree bottle can pretty safely assume a 900psi bottle pressure, given a decent amount of remaining liquid. That's why you generally heat the bottle to 90 degrees, give or take, depending on your tune. Now, it is easier to read pressure from the driver seat when using a purge system to get back down to 900psi if the temp/pressure has gone too high.

Now, purge kits. The reason I don't use a purge kit is because on a 250 horsepower or lower factory jetting tune up it's simply not worth the cost to me. I already set my bottle temperature before I go to make a run, so only benefit would be to purge the expanded gas out of the feed line all the way to the solenoid. To that, I just manually crack the line loose at the solenoid or do a quick dry hop with the system activated.

Next, teeing into the existing fuel line. Fuel system needs are basically based on your expected fuel consumtion of the entire packaged, correct? If I am making three hundred horsepower naturally aspirated with a carb, why in the world would I run something like a giant Aeromotive 1000 series electric fuel pump. Screw that. Put on a mechanical fuel pump, using the stock fuel line setup, and just the make sure the fuel pump delivers enough galons per minute to maintain a 300hp setup. Now if I want to make 450hp with a carb, regardless if its with nitrous or naturally aspirated, I can still put on a nice mechanical fuel pump rated to supply enough fuel for that power level, then it is safe to tee into the existing fuel line going to the carb from the pump. And the pump only puts out 5 or 6 psi, or if I already have a regulator to get that pressure, I am good to go.

Fuel octane is another one that is often overrated. If that same 300hp naturally aspirated setup only has 9 to 1 static compression, and I have a camshaft that is keeping the cylinder pressure in a reasonable range, reasonable enough to run my same octane up to 450hp, then why not stick with that same fuel octane, since it's cheaper. It's the same thing as the cruise night guys that run racing fuel just so it has that smell when he pulls into the show. Not needed.

I would never bag on anyone for overbuilding the system if that is what they want to do and can afford it, but by repeatedly saying everyone running nitrous needs all this extra crap is just adding to the whole negative stigma surrounding nitrous use. I don't intend this overly long post to be negative toward anyone, but as it pertains to this particular thread, this is how I do it and why i do that way.

You sir sound overly intelligent. Yes you can get away with what you are doing but 99.9999% of people make too many mistakes so you have to build in a safety system. I'd much rather tell someone to over do the fuel system and spend $60.00 for a 5 gallon pail of 110 and add in 1 gallon per 6-8 gallons of regular fuel then to be blamed for them blowing up their 100,000 mile, piston slapping, no oil changing, and never tuned up stuff. I'd much rather have them not run it if they can't add in a few safety items. ps fuel and oil pressure switches also. Again if you are one of the .00001% ...

People could call me whatever they wanted to as long as they were handing me their cash!!! I made more money street racing in the mid 80's than I did working my job and I was WELL paid for that era. Not a minimum wager, making more money than my mother who was a nurse.

I hid things all over the car. Places that you'd never look, behind panels, routing in the engine compartment that you can't see... The BEST... My entire roll bar was a nitrous bottle! Car ran REALLY hard with no bottles in it.

Well it's together and it runs pretty good (still a few fuel injection issues to iron out). Right now Larry (64mopar) has it apart to do some more body work and in the middle of it we started work on his '64 Barracuda which has now been interrupted by the Corona Virus. When he gets back to it I'll try to get some action video.

The other one that got found out because a friend came over to help work on the car and then told one other person and away it went. Of course I said anything you see on this car, you don't speak of to ANYBODY, fell on deaf ears.

I was out and someone wanted to race. I said cool, set up the race and they wanted to see the engine. You can look at anything I had, but you don't touch anything in the compartment! I don't trust you or any of your boys, etc. Open hood, hand goes in and grabs the heater hoses right at the firewall. Got asked, Why would heater hose be just warm to the touch after a 30 minute drive and 180+ temps? DOH!!! Two weeks earlier the friend was at my place "helping". Quite the coincidence. Another hidden routing busted. Ran that for 3+ years. Had a fake plate on the car, I'll disconnect the hose or unplug wires at the solenoid if you want... anything to sell the illusion of it no longer being active.

I routed the fuel and nitrous lines inside the heater hoses with a pair of pass through tubes installed in the intake to get it under the plenum. Always nice to have family that was an aerospace engineer/fabricator handy for crazy thoughts and solutions. Fabbed a sealed box on bottom of intake to keep oil out of the solenoids. Oil was a big problem fouling solenoid seals when located in the block valley. Lots easier if the manifold had a heat crossover, weld/seal crossover at intake sealing surface shut, and open area below plenum. Made for more room.

950psi roll bar...
 
As i said, i will post this up on your thead.
I can post these thing up, all day long, from u-tube.
How many can you post up on turbo cars and supercharged/blown (not talking about nitromethane!!! that's a whole different story all its own.

All that is 90% operator error... the car you posted was probably what doing a thousand horsepower shot or something?...
