KB blower

[jasonh_86]

I was looking around for a good blower, i figure i'm going to go w/either a Procharger or a KB.. could anyone who knows some #'s and some good websites for the KB please reply and post them.. i have already been to procharger.com a million times, i'm just mainly looking for KB..

Peak numbers don't mean much, the centrifugal Procharger will give the biggest numbers, but produce less power thruout more of the rev range.

Either setup should be great fun, but IMO a twin screw such as the KB is the only real way to go. As it will give you big block grunt down low and plenty up top too.

Sorry dude...centrifugal supercharges will not always give "bigger numbers". See my numbers below. I don't know any vortechs or prochargers (maybe a few prochargers and paxtons with the right tune) putting out those numbers on a stock 2v.

Get a KB, you will love it!

well dude!

I'm afraid its science fact that centrifugals can produce more PEAK power. (not on every application, but that isn't because of the blower type it will be other reasons)

MM&FF (I think, there is a link from the KB site to an article) built up a 4.6 and added different blowers to it, the centrifugal produced 50+bhp on a 700+bhp motor than the KB did. However the KB will produce more power more of the time.

But the way I see it is a Centrifugal has the worst of both worlds, it doesn't have the instant low down grunt that a twin screw or even a Roots blower can produce, yet it still can't match the BHP numbers of a turbo.

So I do agree with you Kennebell all the way, its the route I will certainly go.

really depends on what your final RWHP goal is for the car -

I wouldn't buy a P1 Procharger anyway. You'll really be limited on how much power you can make. D1 Procharger is bigger / more powerfull / F1 Procharger is a big ole race version.
Vortech JT trim is hefty
Paxton Novi 2000 will take you pretty damn far too

KB / roots style / twin screw blowers will give more torque / low rpm power, and centrifigual blowers can be capable of much more horsepower.

a quick downshift in my car has never left me disappointed since I never race from 1,500 rpms

when you really get serious about blowers post here in the power adder forum there are tons of guys here that have every power adder there is including twin turbos

hell their shop may not be far from you - now I'm jealous.

Yeah the centrifugal made 50+ bhp but that was only somewhere above 6000rpm or 6500rpm... So who cares... Under 6000rpm it was making way less power, like up to 150+ bhp less.

i'm just mainly looking for somethin that'll give me the power as soon as i put my foot on the gas.. i dont want to have to wait for the boost to gather up thru the rpm range.. such as, when i'm trying to race a car down the street i wanna be able to shift from 3rd to second and walk away.. i'm looking for 400-500 hp, but i really do not want to get into the internals if i can help it..

 

[ADRENLN]

400- 500 id say go with forged internals

You've never seen a Centrifugal blown car make over 411rwhp and 423rwtq? You need to get out more.

Hmmmm 3-2 shift puts you right in most Centi sweet spot and is right around where the twin screw starts to mellow out. This is where the Centi's take over at the track and it's going to be no different on the street.

i'm looking for 400-500 hp.

KB

Centi will make that much power....and more, for less money.

but i really do not want to get into the internals if i can help it.

KB

You're going to need forged internals with either blower at that power level, but the Centi car is likely to hold up better with a more gradual volume of air than the KB's spike right from the get go. Positive displacement blowers make thing lean in a hurry, all it takes is one little detonation and it's all over.

I'm all for KB's guys, but quit being so bias here. Most KB owners talk as though it's the only blower available or worth getting? Is that what most of you guys have to keep telling yourself and others to justify spending all of that money? A KB is a kick-street blower, but it's not the only street blower, nor is it the only one capable of adding serious, fun, usable power to a Mustang.

Sorry, I shouldn't have said "any"...a majority of blowers out there today will NOT make over 400 hp on a stock 2v. I have seen tons of vortechs (with great tunes) only in the 350-380 range. I have also seen tons of prochargers and paxtons in the 380-400 range.

Actually, when you compare the prices (believe me when I say that I always compare prices before I make a purchase...especially when you are talking thousands of dollars) all the other superchargers cost about the same amount. Even a vortech kit when you add aftercooler (the KB has an intercooler so you have to compare apples to apples), dyno tune, installation, etc. will be about the same price. See, my KB came with everything I needed and I installed it myself. Those hp #'s are with the stock KB tune too. So we are not being biased...just speaking the truth. KB's rock!!!

PS. The twin screw does not mellow out. You are so wrong. See my dyno graph (http://www.modularfords.com/forums/showthread.php?p=239286#post239286) and tell me where my twin screw mellows out.

Come on! How about I have dyno proof to back up my claim, what evidence do you have?

These threads always start flame wars. Be careful and use solid evidence.

well.. i have compared prices for the KB and the procharger.. for the procharger kit i was looking at, which came complete w/everything needed including a chip, injectors, and an intercooler it was around $3400.. and the KB 1.7L kit, w/all the stuff was around $4900.. that's my problem.. i do not want to spend $4900 ALONE on the supercharger unless it's gonna make my car so much faster than any other blower out there w/JUST the blower.. that's why i'm leaning towards Procharger..

 

[ADRENLN]

the kb comes with its own intake, i think that gives it a little advantage power wise over others. so in all fairness, on a stock car see if the kb and its intake makes more power then a novi2000 and a p-51, or a bullitt intake. i think they will be about the same.

all im saying is i think that some of the kb power should be credited to their intake.

 

[jasonh_86]

yah.. that's one of the reasons i liked the KB.. b/c i didnt wanna take a chance at putting too much boost on the factory plastic intake, altho it's P.I i still dont want it cracking or anything

Either blower will give you a ton of power. But that power will be delivered differently.

The Prochrager will come on soft and start to really get going around 3000-3500 rpm and build at a rapid rate to it's peak.

The KB will come on strong and low in the revs (down around 2000 rpm) and carry it's power much longer as it builds to it's peak.

If you want peak numbers to brag about get the Procharger. If you want really usable power over the entire rpm range, get the KB.

What it really comes down to is what do you want. Do you want a lot of horsepower way high in the rpm? Or do you want torque all over the place and pretty close to as much hp? Are you building a race car? Or a really hot street car that's fast at the track too.

The KB comes with a new upper intake like someone said.
