FallenPhoenix said:Well the advice is sound for most engines, but for one there are no aftermarket heads for our engines, cams are just now developing, hell we have 2-3 intakes at the most.
FallenPhoenix said:You can bore and stroke the 4.6 out to 5.3 but it's expensive and will not net you a ton of power. It is however a good start on a naturally aspirated motor.
FallenPhoenix said:CAI kits are questionable in thier power gains but you can pick up 5-10hp there. We may be limited by the cubes but our engines love boost for some reason so that's the way most people go for big power.

A full exhaust will give you the best power gains right now, as for making the scoop functional, I wouldn't recommend it as it has a tendency to bulge and potentially fly off at highway speeds if the honeycomb is taken out.

GinoGT said:Cams have been out for the modulars for a little while now.
GinoGT said:On the contrary, take a look over at the Corral. There's some guy with a project, forget the exact name but is has "350" in it. He has a big bore 2V with mild headwork and cams, a few other things, the stock lower intake, and side exhaust. He's putting over 300HP and TQ to the wheels. There's still a good deal left on the table too.
GinoGT said:Any engine loves boost, as long as it's not high compression. Then it just doesn't love it as much.
GinoGT said:CAI's aren't questionable, they're garbage. The majority of what little power they may make can probably be attributed to going from the paper air filter to a K&N-style one. You'll make 5-10HP if you're smoking a joint that came with it.
jbrown said:to get a gt into the 400-450hp range you will need a power adder, stock gt blocks cant take much more than 6-8psi of boost safely. A gt with bolts ons, cams, slick, supercharger at 6-8psi should make 400-450hp with a safe tune, it should be good for mid to high 11's to get low 12's you can do without the cams. nitrous in place of the sc should give you about the same results in the 1/4.
FallenPhoenix said:The design of our heads is a large part of the equation, any engine will take boost, but some are more efficient at it. The 4v motor likes it even more.
Dynos are not the end all be all of power measurement, a CAI will not show gains until your actually on the track moving air and under real world conditions. The CAIs that make power on a dyno (LS1) have large restrictions from the factory and show even more power on the track.
Sage427 said:however there are a TON of things you can do without going the forced induction route or the "Fast and Furiouis" way of juicing your engine every 10min which can lead to damage if not setup properly (did anybody else notice a rise in decked out eclipses with huge wings, painted crazy on the road after that movie came out!?).
