Well, I haven't gotten much reponse from the single turbo group, so I figure I'll try with you guys.

I'm running a T78 w/ GT79 wheel and decided to open my ports up some more since my last motor was mildly ported for twins. Before I put her back together I wanted to ask for everyone's opinions. Any suggestions? I'll post my intake ports tomorrow.

If you look closely at the last pic, you'll notice that I have room to probably square up the top of the port. What are the advantages and disadvantages to doing this verses keeping more of a "D" shape?

 

It's my understanding that squaring off the port does move the torque band higher...keeping it round broadens things a bit...this from the "other" forum and Judge Ito. I've been told not to go too far up either, especially on a street car. I'll shoot you a PM and give you the direct link. You can see images of my port job there as well :-) I thought you would have gotten your motor together and in by now!

 

looks good :-)

 

I have also heard that while a squared off port will produce more peak power in general, the rounded port will give a broader powerband. Looks good though man
