Had some thoughts recently about a 3800 NA W/ ITB's. Anyone done this before and have some numbers compared to the factory SC engines with let's say a 3" pulley and proper cooling?
Since the intake isn't much of a problem with a 3800 I would think the gains wouldn't be that impressive, also I don't know how something like that would even be tuned, might be outside of the limitation of the 3800 PCM. The intercooled 3.0" SC would definitely be faster by a long shot.

alpha N mode would work ok. Tuning it is not particularly easy to do because most of the alpha n tables are missing... but it would run fine. I helped a camaro guy use alpha n before.
After some research, seems if I want itbs an ls1 is much cheaper with better results
lololololol
How did you determine it was "much cheaper" to setup more throttle bodies on a v8 than a V6? How did you determine that they would produce "better results"?

You'd have equal runner lengths, equal plenum volumes, etc. The downside is that plenums and runners are usually tuned to a specific bandwidth, so it may run worse at lower speeds than a single throttle body setup. Plus, you have to "sync" them, each tb/cylinder should pull the same amount of vacuum as the others.
yeah, it looks cool, but then it rains and your motor hydro-locks. Or, you forget to cover your car and a dust storm rolls through, game over. Or you have a really awesome looking paper weight because you can't ever get it running right.
