However you wanted to run higher boost???

The T28 could make a little more boost below 5000rpm but it would rapidly bleed off as the rpm increased as it could not sustain it very well. Also you would be pushing considerably hotter air so the point of diminishing returns is already at hand.

Maybe "nicer" dyno queen numbers but pointless in real life.

With more boost down low you run across even more traction problems! You really want to run less boost down low (below 5k) and more boost up high (5-7k)
You are just not going to get any real traction in our platform.

The 270FWHP plateau is it's "real" limit and that's already stretching it's efficiency range.

Again I am not saying it's a bad turbo just stating it's range of operations. It is an excellent choice for an overall power curve. It is just small IMNSHO. (insert Tim Allen grunt here )

You also made it sound like you wanted more power then a T28 could deliver. (the comment about raising boost)

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
