 Subject: Why is 4.7 aftermarket so shady?

Case in point:
airmax intakes never materialized
g-forced intakes never materialized
eho cams never materialized
hypertech programmer never materialized
no 02+ fipk
no heat shield/box on volant intake
no catback with measurable gains
Whats the dilly? This engine has been around long enough that "it's still a new engine" excuse just aint cutting it no more. I have an 02 4.7 and have some money I would love to turn over to the aftermarket, but where they at?

Since I don't show my truck at shows, I made my own true cold air intake, doesn't look like painted ceramic, etc., doesn't cost as much either, probably works as well/better though. The HO cams, Ho intake, etc. do pretty well, they are mild though, kinda glad though also.
They did pretty well from the factory.
How come the engine in the tundra, 4.7L v8,
with the DOHC, 4 valve per cylinder, only puts out about 5 more ponies? 'Cause Dodge kicked but on this engine from the factory!

On the other hand, the 4.6L DOHC V8 in my Mark VIII puts out 290 hp, which makes the 4.7 look a little lazy. Torque is at least about the same.

dc spent a lot of time and money on the 4.7 exhaust, so much that headers produce only 2 hp. thats right only 2 over the stock manifolds and I for one am making a pretty good outside income on the aftermarket intakes, it sure is nice to own a small mfg. company so I can produce my own to sell to you guys, sorry no internet sales, don't wanna end up like berned, out of time, money and customers.

Because the engine is not a caberated dinosor with one cam , pushrods and some hydralic lifters! If a brain dead buba can not just bolt it together and turn a few screws you are screwed!! The only way you are going to get anything out of this engine is to go the "import tuner" route. After market ECM, manual trans and then have cams custom made and pistons custom made until everyone starts copying you. THe factory pistons and fuel tables and timeing tables are so rescrictive that no one wants to touch most new engines. The exception would be in performance cars were you are guranteed a market demand. So it is easier to find complete kits and packages for a Viper that has very limited numbers produced then it is to find packages for our 4.7 Dak witch is sold in huge numbers. THe GM trucks with GenIII V8 get to piggyback on the productes designed for the corvettes..... WHen you do find something like Huges raceing cams the price is so insane that no one can really afford it! What ever happened to the idea of spreading the price of development cost out over 2-4 years. If you like to play the HP game your daily driver is not the place to start unless it is carberated, a General Motors Product, or a Honda!!!! Dodge is on their A$$ for not makeing a real attempt to have HP parts available for this motor!!!!

And now that the Hemi is out, it'll steal whatever thunder the 4.7 has...I heard a rumor that they may start to phase out the 4.7 and replace it with a Hemi-based design.

I'd take a baby HEMI V8 in the Dak. Another reason the Tundra makes more TQ and HP is the fact that is has 4 valves per cylinder, where as we only have two. It's more efficient overall, but I still think we have a better motor with our 4.7L as far as mods go. Ours is way simpler and easier to work on.

Here's a link...
http://www.dragtruk.com/ENTRIES/0F64H9L1P5IL.html
I don't have the FMS 21# injectors any more. Other than that, that's all I got.
Most important things you can pick up right now are these
1. Get your PCM flashed by ASE, KB, or Leach (2000 and older trucks). Do a search for contact info.
2. Get some cams. HO Jeep cams, KRC 206 cams, KRC 218 cams, Elite Customs EHO cams... whatever. Get a set and drop them in. It takes 4-5 hours.
3. Get a bigger throttlebody and a better air filter set-up. Whether you port your stocker TB or get a huge-errific model from F&B or Fastman. Whether you buy a K&N drop-in or a $$$ Z-Tube, doesn't matter. Just get more air IN the motor.
4. Get the exhaust system enlarged to a single 3" pipe from the end of the y-pipe all the way back. That includes the 3" cat and a 3" muffler. Doesn't matter on brand names or noise levels. Just get more air OUT of the motor.
5. After those steps, then you can start looking at stuff like the HO intake manifold, removing the clutch fan, short belt for the track only, whatever.
That's pretty much the basics. Those first four things will act oddly if they are installed in separate steps, but once you have all of it in place, your truck will haul ass compared to factory stock. If you are worried about losing low end torque and all that BS, look at the dyno graph at my link. I don't know how much torque you need for bottom end, but starting at about 2000 rpm, I've got tire smoking torque. And that's not a figure of speech.

Hey they used a "tester" for the heads, I'll "TEST" the cams.
How fast do you want to go dude? Got money?
Get a charger or some nitrous, heads, cams, intake, throttle body, computer flash, slicks, traction devices, cold air intakes, headers, shifter, ........
All of the above are out for the 4.7L now.
I've got the inside scoop on how to get 301RWHP and 351RWTQ out of 2 bolt-ons, and one of them is a muffler.
I'm waiting on the Superchips Micro-tuner, and more money...A good tune on this thing, and a couple more tricks, and it will see 400HP.

| Cold air intake seletion for 4.7L

Message:
I am looking at an airmax cold air intake for a 2003 4.7l. AIrmax has these for the 2000-2001 models but none listed for 2003 like what I need.
Does anyone know if there is a difference between the engines from 2001-2003
I am also looking at a helix throttle body spacer to match. Any comments ?

Why would any manufacturer waste money on an engine that captures less than 1% of it's market? Ford and GM small blocks rule the roost and whatever they don't get goes to Honda.

Couldn't you install a Jet preformance chip?
Also if couldn't be emissions have nothing to do with it. If there is a aftermarket for V10 powerd Fords, then it sure could be on for a much smaller 4.7 with two less cylinders.
