Top end rebuild or supercharger?

they were awsome vids. When I talked to the guy at PIE I can't remember if he said it was
an sts turbo that they completed or if it was something else entirely. I whole heartidly agree
that turbos are a great way to make power, it just depends on your application. If I were to
build a strictly street rig I would definately want a turbo, they make gobs of power, and if I
was running street I wouldn't mind turbo lag. I do a lot of different things with my truck
including off road use and a rear turbo would get completely trashed.
I don't know if this debate would be the same if we were talking about an engine with a
higher capacity for revs. Not sure how a supercharger would respond to say like a v-tec
motor that runs into the 8k rpm range. My best guess would be that the power increase
would fall off but it would also depend on what kind of SC and what brand of SC.
Anyway, hopefully the OP notices that although we didn't always agree on forced induction
he realized that we both (along with others) agree that a top end rebuild would be a good idea.

Yeah, what I was referring to with the HP loss was with high rpm applications. I honestly dont remember where I got that info from but i cant seem to find it again soo im giving it as a "need to find out again". But, as for force induction, again i completely agree with you. Its all applictation. For me at least, i honestly couldnt decide if i would want a SC or a turbo. I love the whine of a SC and thats awsome power along with awsome looks; and with a turbo i love the whistle and i love the power. Sooo hard to choose.
+1 though for the top end rebuild, thats all that really matters in this case.

a centrifugal design. They work much like a turbo in respect that they don't come into effect
until higher rpms. Unless you can find a used Kenne Bell like I did you won't get that instant
boost a low rpms. Have you checked out http://www.superchargersonline.com they have a
lot of good info on the different superchargers out there.

Like supercharging vs. turbo it all depends on your application.

Hmm wow, good reads. Seems like we'd either want a centrifugal or a root for our rams. Mostly though a root, or a good turbo setup. Really cool.

Roots are some pretty sweet superchargers. If I could have found one I think I might have
gone for it over the twin screw design I have now. But then again the twin screw is nice
because it produces less heat while giving me 2/3rds boost by 1600 and full boost by 2k.
Oh the choices!!

setup, the supercharger is mounted to the passengers side of the motor while the TB and
air intake are located on the drivers side of the motor. Kenne bell uses aluminum duct work
to connect the TB to the supercharger then the supercharger to the intake manifold. All in
all I think it adds around 75-85 lbs of stuff on the motor. It also makes things a bit cramped.

and also an article on twin screw design ....

One nice thing is that I contacted Kenne Bell a while back and they said if my supercharger ever crapped out completely (where they
couldn't even rebuild it) they have newer and better superchargers that would fit this kit.

Maybe some day when I have enough money I will upgrade the supercharger head unit but for
now I will have to keep what I've got.
