spooling is for grandma's priceless!! i like the on/off nature of my kit lol it's like vtec LMAO
but I get to use regular when i don't use the kit and i don't use it often enough to really need a turbo or have i spent enought to buy one
it's a part time power adder i don't need a turbo to commute

Aside from the fact nitrous is now illegal. Do you really want a compressed oxidizer in your car? Think about a paramedic or fireman having to deal with a rescue with a highly compressed oxidizing gas (more than likely poorly installed) in a vehicle.
Bottom line, if your running nitrous in a street car. YOU ARE AN IDIOT
Besides that, a turbo or SC is definitely greater than N2O.
Onto the S/C - Turbo debate....
Turbo>S/C slim margin, but a real one
Why you say -
-parasitic losses for one.
-Homo belts another.
-The whine noise gets irritating. Cool at first, but so are paddle shifters
-Fixed to low pressure levels (on most S/C design - ie roots/eaton)
-Difficult to intercool (LHT has a nice setup, D's are discontinued tho)
-Centrifugal units need oil lines (yeah I was surprised too!) ex Vortex
-Boost isn't ON DEMAND like it sounds.
The pressure levels you experience in your IM are based on your total VE levels, if you open up your exhaust, boost drops. Also, Boost is not linear like most ppl believe from an SC, the flow is linear. Boost will increase and decrease as VE changes throughout the RPM band. Usually this will follow your factory torque curve, multiplied by your increase over atmosphere times your VE. A turbo is regulated with expansive ability, an SC is fixed output.
-Spooling at 3-4k is NOT lag, that is your BOOST THRESHOLD. Lag consists of the timeframe of said application at say 5k coasting, to stomping on the gas. If its a ceramic BB application your talking about the same time it would take your JRSC bypass to close. A fraction of a second. A non BB Turbo is still less than a second. Read a book and then change your exhaust AR on your turbine.
-two words - VARIABLE VANE... it owns S/C even more. More torque ALL the time with lower losses than running a S/C
To end this off. Look at Europe, literally screwed in the arsehole from OPEC they primarily run turbos. Why you say - efficency. VW dabbled with the G-Ladder (which was really neat btw) in their corrado's but was worthless. All you see is 1.8T not G60 on the back of VW's now. BMW, Mercedes, Porche, Pugeot, Lotus, Renault, Ferrari, etc etc.... Who uses S/C - f-ing old buicks and pontiacs...really no comparison

With a supercharger boost is definately not linear, its more the torque curve thats very linear. However you'll be seeing positive pressure within 500rpm or so after punchin it with a s/c....ur car made like 2psi very quickly with the jrsc setup you had, even at very low rpms, which isn't full boost, but positive pressure nontheless. Did you ever have a boost gauge on your car with the jrsc? It would make boost at like 25% TPS iirc.
Superchargers are better off on an engine that already produces a lot of torque, i.e. a v8. They take power to make power (parasitic loss) so the higher the torque output of the engine the better the supercharger will work...essentially. Turbos are incredible on v8's so i'm not saying s/cs are better than turbos on v8's...what i'm saying is superchargers work better on v8's than small displacement 4 cylinders (hondas)

i was looking into sc/turbo for my k20 type-s ep3 ....
most people with k motors who SC, find that after 10lbs of boost - due to heat, they run into detonation/knock issues.
with a turbo that can be fixed with a good intercooler...
unless with the SC you wanna do REALLY high octane gas and meth injection.....meh.
and, the sound of a blowoff is hot
