[quote name='bobmoheb' date='Jan 25 2005, 12:44 PM'] just to let you know a supercharger can be upgraded (add more boost w/ a smaller pulley)

 

Comptech's blower kit uses the Paxton Novi-1000, Vortech uses their own V-2 SQ SC compressor. Note that Vortech and Paxton are sister companies.

 

If you're going to spend the time and money, and do it right, a turbo can be a great option. Since you can up the boost more easily and even got to a larger turbo it is more capable of larger HP later on. It does require work though. You can't just slap on a turbo and leave the rest of your car stock. There is a lot of dyno tuning and a lot of extra parts you may need to buy such as an oil cooler kit, larger injectors and internal parts help also. I would go with a FMAX turbo kit. Or a custom kit using HKS or GARRET turbos. It sounds like you would be much happier with a turbo than an s/c even if it was a Novi 2000 boosting 15+psi.
There are a few ppl on that are running turbos so they can give you much better info than i can. Good luck, and with either option, S/C or Turbo, I'm sure you will love your S even more!!

Another thing about the Novi-1000 vs Novi-2000, the snail is an inch larger in diameter and about 3/4" wider. For those that have the Comptech kit, you know that you have to bend the lip on that cross beam bar in the engine bay for it fit in properly. I'll have a new challenge fitting this unit in the engine bay, you can only bend lip on that beam so much, cutting, welding and reinforcing the beam may be necessary to keep it's integrity. I'm not there yet, but I'll find out soon enough.

Also, the oil feed and return lines in the Comptech kit are not compatible with the Novi-2000.

I've got several custom made pulleys ranging from 4" to 3.1", not sure which one we'll end up going with. Rough estimate from Paxton is that the same size pulley on the Novi-1000 produces another 3psi on the Novi 2000.

 

i have a novi 2000. its double the power of the 1000 at same boosts.

 

One of the other things I haven't seen anybody address in this thread yet was the emissions issues with a SC vs. a Turbo. As I live in CA, I didn't want to have to deal with having non-CARB legal parts under my hood, therefore I was stuck with either the Vortech or Comptech kits (and pretty soon, another CARB legal option is the Elda turbo kit). None of the currently available turbo kits are CARB certified, and are therefore "for off-road use only".

I ended up getting the S/C for various reasons, some of which I've listed here:

1. Less "tuning" involved - The only tuning I've done was getting the car on a dyno, checking my A/F and having my FPR adjusted accordingly. Less than a day on a dyno, and I was done. Keep in mind that I only did this as a precautionary measure, basically for peace of mind that my motor was running good. No knocking, sputtering or hiccups before or after the dyno.

2. From my research, I concluded that it would cost me less to get up and running, and still get a decent amount of extra power out of my car. I didn't need to spend any extra money on engine management, injectors, tuning, etc.

3. I got my Comptech kit for a great price through one of the group buys here on this site.

So far, I've been happy with my S/C, and it's been running trouble-free for almost the past year. From all the information I've seen on this site, I've barely seen anybody complaining about problems with these particular kits (if kept in stock form). When trying to squeeze more power out of these kits (through use of boost pulleys, different engine management, etc.), well that's a different story altogether.

 

I went through the same points as 73Zero. Comptech SC was plug and play, CARB legal. It's also unplug and sell when it's time to sell the car with essentially no evidence the car was SC'd.

I wanted more power but don't have time for any hassles. No hassles was, incidentally one of the reasons for choosing the S2K in the first place.

 

Can't compare a 8psi turbo set up to a 8psi blower set up...will toast you any time of the day from any speed.

 

i disagree... unless you have a turbo the size of a human head.

 

From what I've seen, he's right. The turbos spool up faster, and since you're in boost earlier, that's a lot more area under the curve.
I will entirely agree that an 8psi super will not be as fast as an 8psi turbo. However, the super car would last longer and be easier to set up. It's all about priorities.
