efficiency of HF manifold?
i was just wondering how efficient a hf manifold will be under high boost..i know it is cast so it would be pretty sturdy...i have one on my d16 right now and just worried if i get boost crazy and turn it up..i'm running a t3 right now....

yeah, your right. I would think a nice tubular mani would flow much better. But the hf really isnt that bad.
you could probably clean the ports out some. HF's are for the budget racers lol, like me

I donno you would have to do some major porting to make it flow decent for high hp,
whats the highest hp you have seen using the HF?

from a flow pov
the HF should feed a turbo better than a log mani, especially if ported out b/c it has better transitions. (Tho, custom logs can be fab'd to accept A/C, P/S and such.)
However, the HF will never be as good as a 'ram horn' style mani.
IMO.

You could run some t4 compressors but you would have out the torque mount if you have a standard adapter plate.
There have been lots of inventive posts lately though that don't use a standard adapter plate, then you can fit any turbo you want in there.
