even with FI you will have the restrictions. but trust me having more power than a standard non-Terminator Cobra and walking ******** in 05 GTs is fun

Uhmmmm I dunno about what he said about the Mach 1.

Here are some flow specs to look at.

I have not changed out the gears yet. I guess I'll do the UDP's next. I was looking at a bunch of different kits but have no idea which to go with. Saw some ranging from $190 to $350. Anybody have any suggestions and reasoning why those? Budget doesn't matter on these.(and no I'm not going to skip that and get the m112...not yet at least)

Btw my laptop crapped out so I'm only able to respond from my iPod.

If you ever want to do a supercharger, skip the UDP - you'll only go back to a stock crank pulley later.

Save for some real power instead of trying to squeeze out 4-6hp a couple hundred at a time.

go with some 4.10 or 3.73 gears with a new diff. huge difference. you don't get any power but it's the best thing you can do for under $1000

I just swapped the stocker for a 70 mm accufab and I ground out the stock plenum. The throttle response is definitely measurable as far my butt dyno goes and revs quite a bit quicker from 3000 rpms to red line. I won't say I gained any real power but it sure is more responsive

And I bought 3.90 gears yet to be installed but if you wand any real performance 3.73s are minimum

OK, not the one I was looking for but here is a side by side comparison of power added by mods on a new 5.0. Notice that there isn't a lot of power made from the throttle body, and that's not just the TB, that's power for both a larger Tb and upper plenum. A lot of this "power" and "throttle response" is in your head, 1-3 hp isn't noticible, if you want to notice a huge power difference from a real mod, come to my house, I'll take you on a run in my Cobra then take you on a run in my 5.0, you'll notice a real difference in power and throttle response there. 5.0 will spank my Cobra all day long.
