Total load of *****, it looks like a nice piece too. Considering it's "tunnel ram" design, I'd like to know how it performs down low. The Edelbrock Pro Flow has proven itself to be sluggish on the bottom but nice up top

If all else is equal, longer runners mean more tq down low....

In for more info as well, seems the long runners would be similar to the longer runners on truck vs car intakes, should help down low? So why would these intakes make it sluggish down low?

I would be extremely Intrested to see the performance of this intake especially the lower range of power say around 3500 rpm and up!
