Will nitrous provide more/less engine wear than a supercharger. Yes, I realize they differ slightly but they're both force fed. Just wondering the downside to either/each. Any takes. I realize some of the differences like price, low end torque, etc. But I need other takes.

NOS requires very good engine management when it is sprayed. If the timing and A/F are controlled very well - you should enjoy great service out of it.

Blowers also need good control but its easier to get it right - but costs a lot more.

I'd go blower because I like it better but NOS will give you more power for your money and there are tuners who can do it right for you.

Doc ,I think its fair to say that that most guys who choose to install and SC over N2O do so because they want that power available at ALL times .
Not to mention the fact that if you cost average the N20 over a period of 3 years estimating that you are going through a bottle a week..You would have paid for an SC .

If your thing is to run your car in the 1/4 mile and don't really mind the inconveinience of always filling the bottle then I would suggest N20.

If you like to kick a little ass on the highway and like having the raw power 7/24 then I would suggest an SC set up.

Either way you should look at getting forged pistons installed.

:twocents:

Good Luck !

As an aside, I think that NOS is illegal in most states whereas SC's are not.

do you have a purging unit? where does it purge? out the naca duct? I've seen one do that and I've wanted it just for looks (cheezy, but oh well).

The entry price for nitrous is around 1/4 of the cost of a supercharger installed and can have comparable power.

The other benefits of N2O are that it is invisible to the car when turned off, which means better gas mileage, less wear, etc. And it's fairly easy to pull out a N2O system for dealer warranty work on newer cars.

I think that most of us who have N2O would want a supercharger in a heartbeat to have the power available all of the time. But cost is usually the deciding factor. Especially if you only use the extra power rarely. The Viper is plenty fast for the street even normally.

you never have to re-fill a S/C or lose trunk space to hold a bottle or two.

That Is so true.

That all depends on who you buy it from.

DLM
Heffner
Roe
And others

It also depends on what other Mods you have done to your car in Conjunction with the S/C.

That's why I used the word " think " /images/graemlins/supergrin.gif <shrug>
In NY/NJ/CT you can be ticketed because of the compressed NOS bottle. Other than heresay, I really have no idea beyond the states that I usually drive.

NS is right. The cost is very variable on alternatives. As an outline, you probably HAVE to spend $8,500 to buy and install the Roe (bolt-on) SC. But you can add logical mods to the set-up to add another $2,000 - $5000. DLM and Heffner are much more integrated systems and will run from $15,000 and up ("up" can easily get to $25,000 - $30,000). Others here may critique these numbers, but the previous should give you a "feel".

At low end of the price range for supercharger systems are the Roe twin screw supercharger and the Paxton centrifugal supercharger. The Roe system retails for ~$7500 and should provide about 150 extra horsepower to the tires. The Paxton kit retails for ~$8,000 and claims a little more than 150 extra horsepower due to a higher boost level than the Roe blower.

Just remember that the Roe system (at that price) needs to be installed...Not sure about the Paxton system.

Also the DLM and Heffner systems require delivery and return of your car to their shops.

Now that is with the stock pulley on the blower.

If you change out the pulley you are pushing up 14 lbs of boost with the Roe system.

This is what I'm doing.

Along with these mods:

- Heads
- Cam
- Smaller pulley on S/C
- Bigger Radiator
- 70 mm TB
- Front Sway Bar
- Balance and Blue Print engine.
- Boost to 12-14 lbs
- After Cooler

This does not include the mods already done to it. :devil: :devil:
