I'm building a 2.8l V6 for my MGB GT. I know its not an Alpine but the engine gives us common ground. I've had and interest in these engines for 30 +years but never done anything with one.
Having been in the race engine, and manufacturing business for almost as long. The right opportunity came to me to pickup up a good core engine for very little money and thought I would go for it.
Years ago I had some information on these engines but it wasn't much. Figuring that so much time had gone by that there would be more parts available and information to go with it. Turns out the evolution of the engine has moved but a freckle in the decades since.
I'm not trying to build a race engine, I want what most people want, decent idle not stock but not too lopey, broad powerband. Something with good street manners but will pull to 6500rpm if I want to shoot up an on ramp. Pump gas weekend cruiser.
Correct if I'm wrong but it seems like making 200 streetable hp is tough. There is very little dyno information, some vague head mod insight but no real flow bench data that I can find.
I know that there is a book that was written some years ago, some people thinks its great and some think it isn't worth the time go figure.
Having built race engines competed in Engine Master Challenges (too bad the last one was in 2019) I figured we would strike out with kind of a clean sheet build and see if we can't come up with some decent results.
It shouldn't be tough to make 200-210 streetable hp, some analytical investigation and possibly a little bit different recipe may be required to make it happen.
The induction is always the first place you look to see if your goals are possible, the 2800 has some curve balls thrown in the intake tract that will need straightening out . We have spent a considerable amount of time flowing the heads and the intake manifold. You have probably seen modification to the stock manifold , here is a video where dig into the cylinder heads.
