| 460 inch Big Block Chevy, twin turbo, liquid/air intercooler. 800 HP @
| 6000 RPM currently, requires only 80 lb/hr. However, it is well within
| reason for this setup to put out 1000 - 1100 HP at 6500 RPM, requiring 105
| lbs/hr. I don't think it is such a good idea to install injectors
| sufficient for current, unmodified, output levels, when I can simply turn
| up the boost, and make some other adjustments, to add HP. I want a
| reasonable amount of overhead to add HP over what I've already got.

| Thanks. That's what I'd heard.
