Centri blower or KB?

[ninety15.0]

I will be going with FI in the spring and i have some important questions that i need answered before i make a final decision. I can get a good vortech setup V2SQ with cooler or a KB 2.2L setup for roughly the same price. I want to go with a nice blower and run 9 lbs of boost and be done with the power mods. I have installed, tuned and driven a SN 5.0 with a KB and bolt ons and the car was insane! Full boost by 2200 rpm. BUT my motor is already a little sluggish in low RPMs and i dont know if a KB setup will work well with my combo. It seems like a centri blower may be better suited to a higher powerband car? For those who have centri blowers on HCI cars, how is mid range power and boost? say from 2500-4000 rpm? thats where im most concerned! let me know your thoughts and experiences! thanks

Centris START to make their power at 3000 RPM, so your bottom end situation won't improve. This whole situation depends on what you're looking for: Instant power anywhere, or a top end screamer. A KB will wake up your bottom end big time.

In my opinion,,street car = KB,, Track car = Centri..
Everyone has their different opinions,,if I did it all over again,,Id go with twin turbo's..

Anything that Daggar wrote in this thread I would read if your considering a Kenne Bell.

Thanks for all the info guys. I read that thread you included and it has some good info as well. It seems like everyone is in the same boat...non-intercooled KB or an after/inter cooled centri. I think for ease of instal and my current powerband a centri would scream at high RPM....but i love low end TQ. keep the advise comming.

it trully is about what you want the car to feel like and what its duties are.... for a street crusier ....i dont think there is anything better than a KB....but if your looking for a dyno queen then centri-supercharger or even turbo


edit: and the whole not having an intercooler thing is now total bs......you could get a snow water methonal kit if your worried about cooling

true true...i have though about a turbo setup many a time...but it just means so many additional install issues and i have never personally worked on or tuned anything turbo related. I think for me an intercooler or aftercooler is a must on a centri blower for stayin real safe. I want to run just 9 or 10 pounds and be done with it. that will put me around 400 whp...and honestly thats enough for me. But i want it to be safe when i beat on it on a hot summer day too...so keepin temps under control is important...and it makes tuning a little simpler. thanks for all the advise though...anyone with an aftercooled vortech setup out there!??!

snow water/meth injection for cooling a KB, if you want low end to compliment your top end I'd definately go with a KB.
