you will switch over to permanent boost like sc or turbo after running out of NOS a couple of times LOL

Yeah personally I'd feel better reliability-wise with an SC than the N₂O, but I have limited experience with all of this (never on my own cars, just friends' cars). Whether I do any of the above is highly dependent on who makes the kits and how I feel about them after they're released (and even then, maybe after some testing by others).

Just a pet peeve of mine is all. NOS is a brand. Nitrous, is what you want to install - no need to say N2O

.

If I do an SC (which I want to do - 400 WHP is my ideal goal), bare minimum I'd be changing out the rod bolts and head bolts. Changing out the bottom end right off the bat might be silly, because that power amount isn't that drastic...I don't see why 400- WHP shouldn't be easy for this motor to handle...

I ran juice on my LS1, and it was great at the track. But thats it...I don't know, I didn't exactly street race much, it was overrated to me.

Its the cheapest power per dollar upgrade you can get, and can be very reliable with the right precautions in place (window switch, fuel pressure safety switch). Although, reliability issues with a supercharger? Did you install yourself? S/C's are generally very reliable, particularly if you aren't running some obscene amount that pushes the car past its limits...

If I were to install Nitrous, I would most likely go with NOS, the brand. Hence my use of 'NOS', the name. But your point is well taken, as my question was intended as 'what do people think of nitrous', not 'what do people think of this particular brand of nitrous'.

I had a Stillen kit on my Maxima (Vortech blower), and it was installed by a performance shop. The same guy who has installed all my 370Z stuff, in fact. The issue I had in particular wasn't with the SC itself. What happened after the SC was installed was an intermittent fuel cut-off issue. I'd step on it and every once in a while, all power would just cut out. If I lifted off the throttle and nailed it again, it'd come back. But it was really annoying. I had the car dyno-tuned after installing the SC and everything. I have no idea what caused that. Maybe there was a problem with the Apexi fuel controller we were using or something. In any case, it's made me apprehensive about going down that route again is all.

Bobo, any other reasons you would like to run a SC over a turbo? I feel like a SC would be better for me as well. I think I would better appreciate the power/reliability/cost of a SC over a turbo.

I was just wondering.

Actually the oxide is the important part of N2O. Nitrogen is an inert gas, it is the extra oxygen molecule that separates under heat and pressure that is important.

Probably the bigger issue is will the block take the extra heat generated and what are the resulting oil temperatures going to be.

Turbo's are a great option too, but unless you're running a smaller turbo, down-low power tends to suffer, and turbos tend to peak more. I'm interested less in peak power, than I am with power across the whole band. In which case, SC's are a fantastic way to build instant power down low (which is something the 370 needs badly...). Its unfair to say really, but I feel going for twin turbo setups is, in many cases, ridiculous because its only for people who want to shoot for the moon and say they made *insert huge number here* WHP WOO HOO! Will it ever be utilized? Probably not.

Also, running a turbo will require changing out your exhaust manifold, and may make passing emissions testing a royal PITA, and seeing as Im in a state that requires that, its not worth it. Whereas, a supercharger is quite happy with stock exhaust manifolds and a nice cat back

Thats a couple reasons right there for ya.

I'm just yankin' your chain dude!

BTW, why not NX or another brand that gauges its shots based on wheel horsepower instead of crank?

Actually, it drops intake charge temperature, and the only very noticeable effect is increased cylinder pressures (which is the thing you need to worry about). Particularly, using such a big shot to just blow a rod through the block. Burning a piston/piston ring can happen too of course. Either way, the key is to make sure you're spraying enough fuel to compensate, and to not use such a big shot that your bottom end wrecks itself.

The blue bottles that NOS uses would match the color of my car better, that's why. (I'm just kidding.) I haven't really researched all the different options on N2O, to be honest. NOS is just the brand that I used on the Maxima, so it's what comes to mind any time I think of nitrous oxide.

Nitrous Outlet tends to make some quality kits, that are well priced. Might look into them too. I think they gauge their shot based on WHP, also...

PS - sorry for whoring up your journal btw, RCZ

Yes intake temperate does drop (because it's an expanding gas) but burn temperature is higher due to the highly oxygenated atmosphere and additional fuel burn.

It's usually not a problem as you're only doing this for a few seconds at a time typically.

Oh geez...

Hey man, I'm still 15th runner up!!

Of course Im kidding. Im kinda sad today... Im about to run out of gas from the tank I filled up over the weekend with 108 Octane race gas....

Interesting ... did the car respond well to the race gas?
