Guess I will have to agree to disagree.. F&B TB they designed a 52x55 that flows 1000cfm. Thats the next step up from there 52mm that flows close to 900cfm and gives a nice bump in hp/tq on these motors but with the formula/math it shouldnt because the motor only requires 525cfm. I do have a 52x55 on the shelf that was on a 360 with bolt ons that ran like a raped ape through out the rpm range (5200 daily). No driveability issues what so ever. Performed as advertised thats because F&B understands how this all works. Like designing the blade for better off idle characteristics. Something that can not be done on a fuel flowing carb. Take a 1000cfm carb on same motor and you would drown and choke the poor little mouse. Would not start with that much carb let alone drive. Without displacement (318/360 mouse motors)let the gears give you the low end needed for towing ect ect and build for hp to keep you going. http://www.sporttruck.com/techarticl...s/filters.html another article that supports the 14x3 and is the best bang for the buck for an intake. MY last response on the subject. Let the audience decide.

 

I think part of the problem we are having here, is you are misinterpreting what I am saying.

Also, I am talking about stock, or lightly modded motors, not motors specifically built to take advantage of higher flow rate tbs, induction systems. That is an apples to railroad ties comparison.

I am also talking 'bang for the buck' here. As I have previously stated, spending 300 plus bucks on a CAI, that in reality, isn't going to be any better than the stock system for 90% of the average persons driving, is a waste of money. If you have a built motor, that can actually take advantage of it, that is an entirely separate issue.

That article is somewhat lacking in any empirical evidence...... Show me some dyno runs, THAT I will believe.

 

I would like to see this rig CC5.9 has. Put a 14x3 and take time off 14x3 will just pick up all the heat from the motor bay, 1000cfm will be a bog monster with just bolt on's, over 5200 rpm daily, please...........and let me guess this is with a stock tranny right.

Looks like you ran this truck at the track post up some time slip's and some photos of it running the track.

 

I run a 14x3 and haven't noticed any bog from the heat in the engine bay... But that's just me...

 

I never said a 14x3 would make it bogg did I. Hot air is the last thing you want in a motor, gotta think air density/charge at diff temps and the effect it has.

 

True.

I think I just worded my reply poorly.

 

^^^ No worries Stewie

But right from the F&B site.

2x52x55


Applications: 1992-2003 Stroked 5.9L V8

The F&B 53x55mm throttle body features a radically profiled 17-4 PH stainless steel shaft for maximum flow and 53x55mm Oval "easy tip-in" plates. This TB flows the equivalent of two 56mm bores. (980 CFM at 25") The kit includes a new factory gasket, all new 18-8 stainless steel cap screws for your factory sensors, stainless steel hold down bolts, and the F&B billet seal nut with Renzoni bridge mount for your airhat. The manifold opening and factory gasket must be enlarged for this throttle body. We recommend the use of a MPI 4 bbl w/2 bbl adapter or the MPI 2 bbl manifold from Mopar Performance to optimize your setup. No modifications are required for most aftermarket air inlet systems This TB is for stroked motors over 360 ci or heavily modified 5.9l motors. displacement.

 

Knocking the ridges off and blending the TB combined with cleaning up and knife edging the blades, then blending the ports on the manifold and cutting down the runners...along with a cam...and now a tune...and it's still slow as hell. Best single mod...none, some made it worse until the cam went in, namely lopping almost an inch off the runners and blending everything.

 

You've done a few things to let more air into the engine... what did you do to let it out?

Look at the mods in my sig (in order done)... Hemifever was a nice bang for the buck, but not until I did the LT's and exhaust did did I realize the benefits of the earlier inlet mods.

 

Just ebay headers ....y pipe is long gone...and 3 inch to side exit exhaust in front of rear tire, flowmaster super 44s
