not sure on how to ask this ? How do I ask this?
Has any one built a special induction system, for their procharger, vortech, paxton, powerdyne, or turbo?
the reason why i ask is because i know their are many DIY guys in here
That have the time, tools, and shop to do it in.
most roots and twin screw superchargers mount in-between the throttle body
And the engine block.
even the side mounts have tubes so that the supercharger is right in the middle of the throttle body and the engine block.
has any one built their centrifuge supercharger in the same fashion as any of the side mount Superchargers?
If yes what were the gains?
Did boost come on sooner?
Did the horse power and torque curve change on a dyno run?
How must sooner did the power and torque start on the rpms in the dyno graph?
How much more torque did you see in the lower rpm band on the graph.
Did top end horse power and torque change?
boost pressure from a centrifuge does not happen until the blade in the throttle body opens past a certain point to allow the boost to come in and make power.
when i run down the highway at 70 i see 2.5 psi on the boost gauge out side of the throttle body while i am seeing 10 on my vacuum gauge inside the intake.
now if i can make a special power pipe to go from the supercharger to the intake and some kind of a J tube to relocate the throttle body to the induction side of the supercharger just like a side mount whipple or magna charger, should I not see power come on sooner.
I'm just asking if any one set up their procharger like a side mount magna or whipple and what kind of gains did they see?
i know by 2000 rpm's a side mount is making around 5 to 6 psi.
and on my set up by 2000 rpm's i am seeing 2.5 psi out side the motor not
doing any good at all, but acting like a ram air on the throttle body.

That is a very nice gain, so I am on the right track to get more out of the unit.
what about the torque in the low rpm band, did it rise to around 50 as well
Or did it climb higher to work with your choose in cams.
Now what about DD?
With the system set up different you did drive with it both ways.
First the factory way and then modified.
How much of a difference was their?
with the extra power did you notice any increase in mileage from the
Factory way to the new modified way?
Were you able to make any dyno runs, such as a before and after.
most of the dyno graphs i have seen a procharger made high horse power
But very low torque numbers.
50 horses and even 50 foot pounds of torque from this mod would make
A total different power curve on a dyno graph from the same set up.

The torque rose as about the same as well.
The difference between factory and modified was over 150 RWHP and 130 torque.
With cam and exhaust only the car dynoed 361 RWHP and 356 torque.
After the modification the car dynoed 553 RWHP and 544 torque.
There was a difference of 192 total RWHP after the upgrades.
Mileage went down form factory a little since I had to get a larger fuel system, but not much. I can get about 320 miles out of the tank on 93 octane.
The numners I listed above are from dyno sessions.

I have a lot of fabrication pictures at my site.
Moving your throttle to the intake side of a centrifugal blower has a couple minor advantages if you are road racing, but will not yield you a different power curve. The centrifugal's are rpm dependent and do not have good low rpm abilities.
