I am curious, at what kind of power level is it worthwhile to upgrade to the vic jr? Is there a better way to know then a power level? Thanks in advance

Ive read that the pi intake is the best "all around" intake under 600 hp but it depends more on your setup and goals. For a street car, Id run the pi but if its an all out drag car Id run aftermarket.

Which year bullitt? Do they help it breath better? I'm going to be buying my old mustang back in a month or so. It's got d1sc and headers, stock heads and plenum and cams. I have a set of mph cams with springs, boost a pump and fuel rails ready for it. With stock manifolds and bad belt slip it was 434/403. Headers helped it a ton and now he put some tacky stuff on the belt and it has been holding up well till I get an 8 rib setup.

There isn't so much of a power level, but more of an RPM threshold. If you've got a really high revving setup (think stage 3+ blower cams with 6500-7000 shift points) then the Eddy can help you out.

PI intakes like to pop when you start forcing 16psi or more into them, it seems. It doesn't always happen, but it does start occurring more frequently at that level. That's the main reason I went with an Eddy. One less thing to worry about.

I have thought about using the F-150 intake from a 2004 Model they are cast metal just like the Bullitt but half the price if you can find an original one instead of that shitty Dorman one..

Edelbrock intake shines in higher RPM, High boost, Nitrous ETC. I don't want to put nay numbers on when to swap as far as boost but for me anything over 12PSI ide personally start looking.

IMO intakes really don't do much for our cars simply because the motors are so Small unlike a larger cubic inch motor which can benefit from a large intake.

Ideally you want an intake that's forward or rear facing(aimed slightly down)runners tuned to your cams, heads, rpm's, ect. Plenum volume that at least equals your engine size (ie. 281). Intakes aren't just a slap on job. Now with our power levels on here for most of us a stock or off the shelf aftermarket intake is great and will do the job we need them to do. No reason to get a 4k Marcello intake or a 3500 plus Berry Motorsports but still need to be picky on your intake of choice and what your doing with your car. There is a lot of great info on the web and very interesting to read about. Well, for me at least.

I'm just getting back into the hobby again so I'm trying to remember a lot of the info. You say the intake isn't just a slap on item, so I should contact a company like mmr and find out the best option? I would guess I could find a plenum from an 04 f150 at one of the many local junk yards. I sure don't have the money to buy a brand new intake and heads etc right now. I'm kind of trying to stock pile stuff so I can tune one time and be done potentially.

Take a look at logan they make nice intakes, Y2k2GT emailed them today and verified they still make them at request.

Mmmm that's weird. Logan told me they don't make them anymore bc demand was so low. That would be great if he started it back up again.

I do have a cowl hood on mine but I can't remember how much more space it gives under the hood. As far as I know, it is a 5.1 stroker, D1sc, long tubes, Ford GT pump. I have MPH cams, dual rate springs, edelbrock fuel rails, and boost a pump sitting in the corner. I need an 8 rib kit before anything though.

Well an edelbrock wouldn't be a terrible decision. Likes rpm's like the d1sc does. The TFS would be a great choice too. Both can be ported if needed as well.
