I hesitated posting this because it turned out to be a failed exercise. We finally got the engine on the dyno and had a number of issues…primarily, because the 2.8l V6 isn’t an engine that commonly is built for performance, my dyno guy had to scrounge or fab the right fittings just to get it hooked up. Then, once we started, the dyno drive plate (which again was sort of cobbled together) separated and acted as a brake during the test runs and we had corrupted data. So, the end result is a very nicely running engine that, based on my engine builder’s computer calcs, should be in the 170-180 hp range (with the Sniper EFI). In my opinion, the 200+ hp engine continues to be an urban legend except possibly for specially race built engines.
Our plan was to test the engine with the stock manifold ( which has been machined, EGR ports plugged, etc) along with the stock 2150 carb, then with a Holley 350, and then with the Sniper EFI. The head work has all been done per DanR’s info and Pruett’s book. We unfortunately never got past the first step so ultimately I’ll put the car on a chassis dyno just to get an idea of how we did. I wish we could have followed through with the original plan because I think the info would be valuable to the V6 community but I’m kind of out of time and $ (for this task anyway).
