Hi Everybody,
I put together a list of Alfa engines with there specs. from this link.

This info might be useful for those who are interested in doing an engine swap. I would also like to hear from Greg Gordon (supercharged V6 engine builder and now working on a supercharged 4) Jungle Justice and his available selection of South African built Alfa V6 engines. And Martin De Campo lets hear about your Greg Armstrong built special Callaway engine. And of course anyone else who has built or purchased a special Alfa engine.

Hi Charlie,
I will have to base everything on REAR WHEEL HORSEPOWER as I don't have the ability to dyno these things any other way. However I have the stock rear wheel horsepower numbers so a before and after percentage increase can be seen.
All testing has been done on engines that have no performance modifications other that the supercharger. All used the factory's L-Jetronic fuel injection and no intercooler, and of course pump gas. I will only post results on cars I have personally tested.

1. Stock 1985 2.5 GTV6 125 RWHP
1a. Supercharged 1985 GTV6 182 RWHP at 7+ pounds of boost.

2. Stock 1988 3.0 Milano Verde 148 RWHP
2a. Supercharged 1988 3.0 Verde 205 RWHP with 5 pounds of boost
2b. Supercharged 1988 3.0 Verde 228 RWHP with 7+ pounds of boost
