NOTE: I already searched, but didn't find anything directly on point.

I like the unit for it's power potential and mostly it's adiabatic efficiency.

A few questions...

1) Is this appropriate for a big, heavy car?

2) I'm looking for a powerband that starts off fairly weak, so as to not blow away the tires out of the hole, then builds up fast as the RPM increases and the engine can eat more air. Is the X-Trim appropriate for that goal?

3) I'm thinking that I want to have a relatively low PRESSURE, but a large volume, so as to add less heat. Can an X-Trim fit that bill?

4) In line with question #3, what heads should I be looking at, to be able to eat a lot of volume quickly, and keep the pressure towards the lower side of it's range?

5) In line with question #4, I believe that I would want to open up the exhaust as much as possible, in terms of valve size as well as flow. Is that thinking still correct, or is it outdated?

First and most important.. what are your horsepower goals???

I believe the x trim moves 1600 cfm as does the ysi trim. YOu might want to think about using a xx trim which moves around 1850 cfm, but it all depends on where you're headed with the car.

I was thinking along the lines of running a large supercharger and oversized heads, to kill some power on the bottom (for a better launch), then have it come on strong in the mid range, once the car is already moving and traction is less of an issue.
I was also thinking that this setup would have a relatively low pressure, but a higher volume.

To put a number on the power level, which I don't usually like to do because I believe it's incorrect thinking, I think 700-750 would make me happy.

There are a lot of different ways to get there, including just buying a ZZ572 and being done with it, or using a large single turbo (or two medium sized one), but I think the centrifugal option has some packaging advantages.


I'm not worried about the bottom end...
I know how to build a strong bottom. That's actually easy, since you just follow a "recipe" to build it strong.


I'm interested in getting a certain behavior out of the engine...

Keep the revs down under 3000 and it'll be a fairly tame driver.
Get into the throttle more and it'll wake up in a big way.
