It's definetly going to take a LOT of CAREFUL planning to meet those goals.

Back to what I HAVE done. I ran a '74 Maverick, 302 low compression, RPM intake and a Powerstroke turbocharger (early powerstroke...model TP38...1.15 A/R hot 1.10 cold). No intercooler, just good hot air. It was capable of 22+ psi, but efficiently it was good to about 14-18. It made enough to split not one, not two but three 302 blocks, right in the mains. One even put a hole through the 6 and 7 cylinder walls...both of them. Serious cylinder pressure, and it was my fault for jury-rigging it together. What kind of power? I've never had one of my own engines on a dyno, can't afford that stuff. It was enough to light up the 265/50-15's at ANY speed and in ANY gear (C4 w/ 2800 stall TCI) on the freeway. 70 mph rolling burnouts were an absolute breeze at 16 psi. I ran it at the track one time....left at 5 psi went about 300 feet and it went ka-pop..burned a couple plugs off due to a bad fuel pump, but still went 1.55 in the 60' and 4.17 in the 330. It was on a good pass. I'd say a fairly easy 6.50-6.60 1/8 mile. It also managed 24 mpg. Stock camshaft at first (out of a '85 Mustang GT engine...Hyd roller) but I later changed to an Erson turbo grind which made the best MPG of the two. The GT cam was ~15-17 mpg, IIRC. Best thing about turbos...you have to keep your foot off the throttle to get any sort of mileage. Once you hear the whistle of boost, your gas gauge will drop pretty quick. My SVO was the same way. 33 mpg normally driving (no boost, low RPM) and maybe 10 if I drove it hard. That was IF it ran (half the time I spent fixing the dang thing!)

Damn dude! That homegrown build sounds like it was way up there on the coolness scale. It also sounds like you were able to knock down some pretty decent milage with a carb. I've never been able to get decent milage in anything. I must have a heavy foot or something.
I was sort of thinking something along the lines of what these guys offer. http://www.turbotechnologyinc.com/tu...er_systems.htm
