Nitrous vs. SC Longevity

All things being constant, what can I expect with engine/transmission life if I compare a 75 shot of nitrous vs. a SC system on stock parts? My engine is nearing 80k miles and I'm afraid I won't even get to use my car long enough to enjoy a FI system. But with that said, I'm not happy enough with the power I'm putting down now, so I've been looking into nitrous.

are you serious? are you going to be daily driving with the nitrous all the time? lol... depends how much you use, how good of a kit, etc etc.. but in general... nitrous would be a lot more risky than a reliable SC kit...

Haha, yea I plan on keeping 10-15 bottles on me at all times and just hold down the TURBO button.

No but seriously, I understand the SC will give me power on a daily basis and the nitrous only when I want it. Either scenario is fine for me, I'm just looking to make a reasonable jump in power without having to worry about extra reliability issues down the road.

a supercharger is very reliable. i had no problem with my car, but then again, i had way less miles.

High torque tends to break things on stock blocks. Compare the torque curve on a car with NO2 and one with a SC.

a reasonable shot would be no different trq wise than any TT/ ST setup. They run TT's on the stock block everyday.

you can get a full blown used NO2 setup for $500. That about 4000$ less than a used SC kit by the time you add guages, ems, injectors etc

Just depends on how you drive. Properly installed and tuned, neither is more reliable.

if you compare power for power.... the Nitrous system will be more efficient due to not having to overcome a parasitic factor in producing the power....the SC will require the engines work to develop the boost needed to make the power....so from a longevity/wear point of view the nitrous will be "softer" on the motor....as it is more efficient.....and the SC will accelerate wear a bit as it is always engaged and being driven....

as stated above...tune is critical.

A 75 HP jet would create 60 lb/ft at 6,000 rpm and 120 lb/ft at 3,000 rpm and 240 lb/ft at 1500 rpm.............obviously everything depends on the rpm you engage nitrous.
