Driving under boost wouldn't really be the problem, driving under every other condition would. The car would be so rich it would probably hardly start and then it would run so rich you could run the risk of washing down the cylinder walls with fuel.

How will you drive with the boost down at 3 or 4? What does that even mean? You cant turn your boost down to 3 or 4 psi. DON'T drive with 650s and no way to control them. It would be horrible beyond horrible.

If you lowered your fuel pressure as low as it would go (about 20 psi), and if you had a 2g mas, you might be able to get away with it. But it's still a bad idea, I wouldn't do it unless you absolutely had to drive the car.

Drive under boost and you'll be fine. Make sure you swap 450cc injectors in though. You dont want to wash your cylinder walls with all the fuel from those 650's.

IF you have a 2g maf and you install a set of 450's than you will be running lean, you can get by with the 2g maf, 650cc injectors by lowering fuel pressure to around 25 base, if you have a logger you might watch the fuel trims because you can go to low and become lean, i've done this before and achieved a very good a/f ratio with just a fuel pressure adjustment. And would you guys quit telling him to run it in boost, that is about the dumbest thing that i've heard on here for a while, oh lets run it hard with a rich a/f ratio, great idea.
