I'm about to do some more mods on my L, so in the process I'll have the chip reburned for the new mods. I'm trying to decide if I should go w/ a 75-100Hp shot of NO2 or a lower pulley to go w/my upper!!!
Need comments from everyone on pro's and con's of BOTH Nitrous and Extra Boost!!!

Pullies - run continuously.
Nitrous - only when required.

If your truck is a daily driver/occasional track visit, I'd say nitrous.

If you want to run hard to work, groceries, etc., go pullies.

Just my .02

 

So, wait, this will probably be a VERY retarded question, but, I thought the supercharger pullies only spun when the supercharger kicked it - i.e. higher rpm. So, in reality, does it spin always, but only gets used when the boost kicks in?

Tampa, are u saying u think the engine will last longer using NOS occasionally instead of pullies and stuff?

00FireRide: Go out to your L and start it up, open the hood and watch the supercharger belt spin the supercharger. It spins all the time. While crusing the boost dump is open and not giving the motor boost but the supercharger is still spinning.

 

They pulleys are always spinning. the boost is "on demand". by using performance pulleys, you are increasing the rpms of the blower, at all times, but now, the starting rpm and top rpm have moved higher

 

As soon as you turn that key, your blower is spinning. Its not creating bost until a certain RPM or load is put on the motor but its spinning.

If you mod your truck with pullies, its not really going to decrease the life of your motor, it all depends on your driving style! If you rarely get on it and the RPMS of your truck barely ever get past 4500 RPM's then your not going to over spin the blower. Which with all of us running pulley's I would be to worried about that anyway.

Nitrous creates more boost, and pulleys do also. they do the same thing just in different ways. Like driving to florida, or taking the train to florida. you'll get there, just by different way.

So when it comes down to it, it really doesn't matter what way you go, because sooner or later your motor's going to let go when you beat on it. Just decide if you want that power all the time, or only once and awhile. Nitrous does have the extra edge of cooling off the intake charge at the same time. Thats why I personally run a 4lb lower with a metco 1.5lb upper and a 50shot of juice at the track for mostly cooling and a little extra kick.

 

tommy: Hey thanks, the question just popped into my head that i had never thought of it before and I am at U of F between classes so couldnt look at the L right now.

 

When you bolt on a different pulley, that spins the blower faster, and it's spinning 100% of the time the truck is running. When you use nitrous, you're only getting the use of it when you are using it. There are pros and cons to both set ups. Pulleys are cheaper, and you have the boost all the time. But you are spinning the blower faster all the time as well, and if you get a bad tank of gas or something, you can't just shut the pulley off. Nitrous costs a bit more for a proper set up, but it also adds more power usually than a pulley, and is only on when you're using it. Plus you have to fill the bottle.

Both methods make power in the same manner. They both add extra oxygen into the combustion chamber. One does it mechanically, and the other adds a liquid chemical.

What would be a good compromise, is to get a less aggressive pulley, and run a smaller shot of nitrous. You will still make gobs of power, and have the pros of both systems on hand.

 

Now that's a great solution...

 

I know for motor longevity that both pullies and NOS are both not recommended. HOWEVER. Having a little experience with pullies on a Tbird SC. I can say that if you run pullies you are shortening the life of the SC bearings. But, my SC ran a long and healthy life until some pot-head kid hit it. The OE SC w/aftermarket pullies lasted 114k. The pullies were on for the last 70k miles too. Thats pretty good IMO. The pullies route big benefit is TQ increases, I have no experience w/NOS systems.

Where will NOS give the biggest benefit, will it just "inhance" the hp & tq that you have when switched on?

Thank for your prior opinion, that sounds like a great way to make the most usable safe power for the daily driver.

 

Performance on the street or performance at the track?
Seems to be the question I keep asking myself.

 

That my solution punk! Don't be steppin, HEHEHEHE

 

Is that what you were trying to say?

 

If you want to post a kill story here make sure you are running pullies only. There are a bunch of cry babies that will yell at you if you use nitrous on the street. It is okay to use pullies on the street. A pulley never got anyone hurt, only the nitrous.
I'm going to be running both pullies and nitrous on my setup.

 

yeah but I started to ramble on, HAHAHAHA. I get that way sometimes, I can't shut up today!
