Yeah, I often wish I had more torque below 3000 rpms

 

To the OP, I know lots of questions were "answered" that you didn't ask. If you have more, don't hesitate to ask. The discussion isn't "silly" to you when you're the one wanting the info. Lots of things to consider.

 

 

A waste would be having a supercharger that only boosts power in an rpm band that you rarely visit on the street

Fixed it for you. Thank me later

 

 

Mine's pretty strong at 6500 rpm....it's also pretty strong from 2500 all the way up. Thanks for the fix!

 

Yeah, my little 370c.i. lazy low compression engine is really lacking in the torque department compared to yours.... come on man, get rid of that pd and step up to a centrifugal setup, you'll be very happy you did!!!

Just messing with ya man... somebody has to give those "in denial" PD guys a hard time!!!

 

I know...it's a sickness and you guys feel the burning need to "cure" me. I appreciate it. You obviously have my best interests at heart. I've got it bad though. Just bought another Maggie TVS so I can run one every day. GMC for work and vette for play. Anything without a Maggie on it feels like I'm dragging a parachute around

 

Haha, come on guys... we have 3 basic groups for forced induction, centri, PD and turbo. Just like blonds, brunets and red heads, pick one and have fun... All have pluses and minuses. If there was a true winner then we wouldn't have threads like this .

I'm somewhat neutral because it depends on many variables, too many to list.

Pick what suits you and enjoy. But at the same time look at growth potential, if looking for max effort down the road.

That's it and added nothing to topic at hand.

The problem with gobs of torque down low is TRACTION! What's power if your spining it all away. In reality everybody would want a 4L wipple on a 440ci vette if it had limitless traction. Sure on the highway you don't have to down shift to destroy that mustake GT with a Roots, but 1st and 2nd will be pointless with anything near stock size tires/compound.

 

roots + centrifugal

/thread.

 

The problem with gobs of torque down low is unless your shifting at 3500 it doesn't matter.

 

I've never heard of anyone that owns a good pd complain and want a centri. The only complainers of pd's are centri owners-weird.

 

And then there is the elite Turbo group............

Flame suit on

 

First of all forget about legal speed. With any kind of Supercharger as soon as you hit the gas you will be flying.

I am also someone that has been considering a supercharger(SC) and have been considering the positive displacement vs. the Centrifugal. Second forget about the Roots type (primarily Magnuson). The Twin Screw(TS) SC are much more efficent for about the same price as the roots. Based on my research the TS offer great low end torque all the way to the redline and does not drop off likes a roots. Also, again based on research (I'm sure people will correct me if I am wrong) the TS offers comparable peak HP to a Centrifugal Blower. If this is true you are getting the best off both worlds. Great low end torque on demand and a respectable 1/4 mile time.

Now this is based on base kits. When you talk about upgrading, you open up a whole new can of worms. Above a certain HP level the Centrifigal is superior because with the TS the torque becomes so great that you cannot even launch the car because of the wheel spin.

I'm not sure if this is a completely accurate comparison, but I have enclosed a link for a comparison between a Kenne Belle (KB) TS and a Centrifigal on Mustang. Sorry if I insulted anyone by bring a "Ford" into the discussion. The KB offered great low end torque and a comparable 1/4 mile within a fraction of seconds.

Let me know what you think,

Let me know what you think,

 

My c6 makes 630/581 with a little SI trim(3.8), and meth. Sure exhaust and a smaller pulley could pull it up to around 700rwhp.

That is the nice thing about Centri's, is that you have room to grow. I also purposefully don't want that tq and boost down low. If you're spinning, your not winning, and without a burnout, 630rwhp will light it up, even with MT's on the street. The centri blower makes it easy to roll in to the gas and keep the car hooked and going fast in a strait line.

 

There certainly haven't been any complaints from me. I just see the more torque down low argument over and over every time this debate comes up. Personally I've never tried to race anyone at 2500 rpms. Downshifting works so much better.
