No, you certainly didn't go "long" on your answer. That was great info and interesting input/opinions. Your opinions with your reasons behind them were very useful past just objective reading in books. I had earlier arranged a setup for a 8:1 3.0 using GT2054's using Webcam's 20/21 and EFI. Now that I'm going 3.3 with traditional 7:1 compression and higher boosts should I even try the GT20's or go ahead and figure on new GT28's. The GT2054's I have use proprietary flanges I've converted to Vbands, so they can't be easy swaps at a later point to a larger chassis.

The GT20's were listed as 260hp and when I used the maps for a 3.0 at .8bar it looked to be in the sweet spot on the graph for a responsive 400hp engine. Is this all just a wash with the engine spec changes? Am I even evaluating the maps correctly for our air cooled 2 valve hemi engines?

Sincerely appreciate your time,
Luke S.
