I have been looking at the two and i wanted yall's opinion on which would be a better choice. I know you can make good power with both but which would be more reliable for a daily driver? I am planning on a H/C/I swap in the next few months and i want to top it off with a blower but i cant chose which one.
 
Prochargers come w/ Intercoolers...Kenne bell dosent....Procharger used to have leaking issues.....No isses w/ Kenne bells. Procharger is cheaper overall and you get more hardware IE.. Intercooler.
 
This is the big debate over on the 03 forums. If its strictly going to be a street car, id go KB. If its gonna be a street strip car, id go procharger PSC2. Full strip car id go procharger F-1. Honestly, with your power levels comming close to stock block limits, youll want the intake charge to be as cool as possible, another + for procharger, as centris are much more efficeint then Roots. But roots are very fun on the street. You have to ask yourslef do you like getting thrown back immedaitly in the seat or do you like gradually just sinking in the seat further and further.

The kennebell isnt a roots blower. Its a much more efficient twin screw. Out of those two choices i would go with the kennbell. I have read too many horror stories over at the corral, mainly seems to be the street blowers that have issues (prochargers).

You need to remember with the kennebell you have FULL boost by 2k rpms, which makes for massive amounts of torque. And great area under the curve. If you do a search on kennebell over at the corral in the supercharger section you will get alot of great information. There are a bunch of fast KB cars over there.

Yes, sorry it is a twin-screw. I keep getting mixed up btwn the eaton and KB. The procharger problems with the seal are long gone though. The KB is much more efficent then the roots, but the centrifugals are much more efficent then a KB. Like I said if its a street car then go KB. If its more of a strip car go procharger. Because on the track your power band is limited in the upper RPMS, where the Procharger shines. Just launch above 5000 rpms and stay in the powerband bwtn shifts and youll loose that KB no problem. but on the street, a kb is a diff animal if your into roll races.
 
I can't believe anyone would use "efficient" and "centrifugal" in the same sentence :p :D.

Personally, I'd go with the KB, for a couple of reasons:

1. No belt tension issues, no extra pull on the crank
2. More power under the curve. And arguable you could run more power overall, since you don't need to turn as high an RPM to make power, and it's really RPM that kills motors.
3. Everyone has a centrifugal blower. Be different and get a KB.

The intercooler isn't much of an issue in my opinion, I'd get a water injection setup (couple hundred bucks for a commercial one), water injection is more effective anyway. Downside is you have to fill up the tank once in awhile.

And the KB can make good boost at the top end as well as the bottom end, it's a myth that centrifugal blowers are better at higher RPM. They're not.

Exactly, you might get the same peak numbers, but then you will be looking like the "dyno-queen supra's". You want power under the curve. If the torque curve is as flat as the desert, then you are running at 100%.

But, if the torque raises with the RPM's, then you will get much less power at lower rpm's(3500-4500). Usually, after each shift, you end back up at around 3500 rpm's or so. You want full boost at 3500 and up. That is what the KB will do for you.

That's a negative, Captain. There was a thread in the 4.6 or Power Adder forums just a couple days ago and a guy with a newer Procharger said he had trouble with the seals 2 or 3 times and had to send it back to ATI each time. :notnice: Evidently the problem still isn't fixed because I still hear about it. I like how ATI includes an intercooler and they do make great power but it's not worth the risk IMO. I'd be much more comfortable with Vortech, KB, or Paxton.
 
I havent heard any in a while, and I know plenty of solid prochargers that are out there.. and yes The centrifuglas produce MUCH less heat then the KB's, at a given amount of boost.The procharger will yield better numbers at the track, but it depends what you like. You have to decide if you like getting thrown back in the seat when u hit the throttle instantly at almost any RPM or steadily getting pushed back until about 4k then hold on. KB has it problems too, if you boost it past 17#'s your going to get oil spraing out of the case, but I doubt youll boost that high, thats for the 03 Boys.

Here is another one, 2 D1SC head units, 2 1/2 years time. On my 2nd D1SC that blew its third seal a few months ago. I havent had the chance to test it out yet, but I can imagine whats gonna happen. ( Total of 7 blown seals with 2 blowers ) The issue is definetly not gone.
I can say this that the 'only' reason I went procharger is because of the intercooler. I am sure that it decreases the intake charge quite a bit over a non-cooled application, whether it be a twin screw, or another centrifugal unit. I am thinking of some data logging software once I get a new motor back in the car, that way I could actually see what the intake temps are. But, I must say that I would not buy another procharger on a bet. If I were to go at it again, I would either do a novi 2000, or a single turbo setup. ( and someday I may )
