I am not 100% on why people with nitrous seem to screw up an engine quicker than boosted folks.
I had 6-7 hp in mind per pound of boost so that would say someone running 9 lbs or so could roughly equal a 50shot give or take, but close for comparison.
Now negating the people who toss nitrous on and put too big of a shot on there or do things improperly, why does it seem that turbo engines which are pretyt much constantly in boost last longer than nitrous users who spray for shoter periods of time.
Again leave out things such at stuck solenoids etc etc, My only guess is that turbo setups are a little more dependent on people having the proper fuel/timing mods etc.
A properly setup/tuned nitrous system, and a properly tuned turbo, with approx the same amount of gains for each, and I feel that the turbo will still last longer when dumping the boost constantly to it.

well nitrous is a lot harder on engines than turbos are.
a lot of "kids" think they can slap on a nitrous kit and spray all they want partly due to mr. dominic toretto and brian spillner. that might last for a while. but the negine will blow up due to these "Kids" not doing there homework. like you need colder plugs, premium gas, WOT and RPM switchs. that sort of thing. heck i know a guy, a month after Fast and Furious came out he installed 6 nitrous kits within 3 weeks time. he had to rebuild 5 of those engines because the owners did not do there homework.
but with proper precautions and tuning you can a 100 shot safe on an engine. example: look at Nitro how long has he been running 100 on his motor? probaly close to a year now.
i also heard of people blowing up the engines with a 35 shot. and i also heard of people getting away with as much as 12 psi of boost on stock internals. but its all about the tuning
Im a Xbox 360 fanboy...and damn proud of it!!
i know the cases like nitro having great luck with it, but figured that enough people would actually take the time and do it properly to hear good stories about it. With my plans, I was going to do every possible thing to do it properly:
fpss
wot switch or TPS sensor (same thing in the end)
dual nitrous solenoids
RPM window switch
colder plugs
in time msd dis-2 ignition
in time safc-2
What all is needed to tune nitrous properly, and why exactly is it harder on engines. In essence you are just adding more airflow, the same general concept, adding more air
I am going to start with a 35, get the hang of it and up it to 50 in time... eventually I want to do 75, and possibly 100 after I feel confident that its all ready for it.
I have been looking at software to read sensors etc so maybe logging and seeing the a/f mixtures, and then using the safc to adjust fuel curves I can understand to match things up better.
In the further future i plan on building internals rods/pistons/cams as well.
What else am I missing anything? I would love to go turbo, but I feel there is much more tuning that goes along with that, and with nowhere local to do tuning I am hesitant. I figure I can install it myself, as I know my way around the car pretty much, it would just be things such as tapping the oil pan I would worry about. And having my car down for a few days while I install is something atm I cant afford.

alot of people around here run nitrous. 50 shot mostly, but there are some that go 75.
1 blew up cuz he missed a gear and still hit the gas.
the other one blew up cuz he forgot to put a jet in.
its mostly user error.
nitrous is harder on the engine then a turbo. it creates such a big explosion in the engine. its not as forgiving as a turbo or supercharger.
as long as u keep the shot a reasonable size, run good fuel, have colder plugs, and didnt eat paint chips when you were a kid, u should be fine.
im interested, why would you use dual nitrous solenoids? to answer your other questions, any good, respectable nitrous kit installed correctly should already be tuned properly. Since not everyone who installs nitrous has an air/fuel controller like the safc, it's all pretty much adjusted by the size of fuel and nitrous jets you use. As long as your fuel pressure is good, this will pretty much give you a proper mixture. Anybody correct me if I'm wrong.
Also, I believe the people who use nitrous blow their engines more than those who use turbochargers and superchargers because of the work involved. Nitrous is commonly thought of as a quick and easy way to gain horsepower, and due to its relative ease of installation, people often may cut corners and take shortcuts without doing all their research. Because a turbo or s/c install takes a massive amount of work, and it considerably more expensive, people often do more research first.
all i have to say is that turbo > nitrous.
I was a retard, and now I'm permanently banned.
run dual solenoids so that incase one fails and sticks open... the other will shut, someone has had that problem and it basically keeps injecting nitrous and makes you lean out like crazy, boom... running 2 prevents that if you run them in series so atleast one will close, jst incase.
I get the explosion part now, makes sence. Doing a turbo yourself, and doing nitrous the right way come pretty close all in all price wise imo, but i jst cant convince myself that the time to install a turbo and properly tune it just puts it outta my league right now untill i get a daily driver...

Well a couple things. Your talking about 2 different technologies which will not equal the same amount of abuse and don't operate in the same manner. Yes a turbo runs constantly but it's not pushing full boost while your going to the corner store. Spraying should only occur while at wide open throttle and like said puts more abuse on your engine especially because you are at full throttle.
The thing is...people have almost as bad as a time with turbos than nitrous kits but you don't hear about it as much because it takes time to usually occur. With nitrous, you could blow your motor the first time you do it, with turbo, it will take some time...maybe a week (if really don't incorrectly), a month, a year, you never know. Also, people who can afford a turbo kit usually can do it correctly. It's the people who try and do custom kits (not ever person who does it) who have problems because they try to cut corners by cutting cost on quality parts or not including parts. Example: people who run a turbo but no inter-cooler, not properly tuning the amount of fuel needed etc etc
