Lemme explain it this way for you guys who dont see the point of JLP's new product. Im in no was affiliated with any vendor, Im just using a little common sense and Mechanical background to come to conclusions.


If you have ever used a pneumatic air tool, you know that the impact gun or air ratchet has more power thru a 1/2 inch hose vs a 3/8 inch hose. Both have the same fittings on the compressor,hose and tool. The fittings (Throttlebody in our case) are not the bottleneck, its the small hose.

 

My feeling is looking at the picture #1 and #2 there is a big difference between the inlet being mostly above the rotors with the stock setup and with JLs setup it may allow more air to come back behind the rotors easier. I don't know much about physics though.

 

Easter, I might be misunderstanding the point of your post. If I am, Im sorry.

Doesnt JLP's new product let you ditch the adapter plate ?


If so all your pictures are a waste of time, except for the Throttlebody.

Are you saying the Pipe is a good product or are you being a smarta$$ and saying it doesnt matter because the TB and blower entry point are smaller ?

 

I don't think the pictures are a waste of time. A lot of people have no idea what the KB, stock blower, TB, and upper plenum measurements are. I think this will help them see.
What JL's adapter plenum lets you do is get rid of the adapter and open the KB up approx 1.75 inches(see picture #2).
I don't really care if the thing produces more power or less power. My KB is on ebay right now and will be sold on Saturday. That is also why I didn't remove the adapter plate and take a good picture.

 

I am glad Easter started this post. I now allows us to discuss this topic like adults, instead of people crying "tuner wars".

I don't claim to be an airflow expert. I asked my question based on what logically came to mind when I saw it. I simply asked the promoting vendor to explain WHY this new product should work.

My thinking is that you have two ends of a manifold. One end has the TB, the other end has the blower inlet. For arguements sake, lets pretend the TB opening has 3 inches of surface area. What would making the blower end opening have 6 inches of surface area improve? You are still drawing through the 3 inch TB end. As far as I see it, having a huge open plenum after the smaller TB is just going to DECREASE intake air velocity into the blower. If you blew air through a 1/2" tube, then noted the air speed out the end of the tube, and then you attached a 2" tube to the end of the 1/2" tube and remeasured, you'd have a slower air speed. The open plenum after the TB decreases the air velocity into the blower.

I don't claim to know everything. If I'm wrong, someone explain why. That's all I originally asked. HOW does it improve?

Going by the responses that some have come up with so far, we should be able to take off our stock TBs, and put on smaller ones, and not lose power. (blower inlet now larger than TB opening)

 

Thru the history of people changing from the stock throttle body to the single blade, nobody ever has proved any signifigant HP or TQ gains, seat of the pants gains from better throttle response yes, but no real gains, but when upper intakes are extrude honed or hand ported, there have been some signifigant gains reported, so with that thinking in mind, I would have to say that the T-body is not a restriction the intake and its ability to deliver larger amounts of air to the blades of the blower is. Opening up the intake to let the KB (of any blower for that matter) get a larger VOLUME of air is a good thing.

Think of it like this Sal,

Your vacumm cleaner at home doesnt have a large mouth on it does it? Nope, it had a small opening and the smaller the opening the more suction you get even though the bag is large and holding all the volume, the efficiency of the vacumm doesnt go down when you put on that small attachment that gets dirt from the corners.

Or think about it like this,

Try putting a 850 Holley on a single plane manifold, then put it on a dual plane manifold that has more volume to it and what do you get? More power if the rest of the combination is ready for it. How big of a difference is the openings from a 650 to an 850 carb? Not much, so obviously the carb isnt restricting the engine from breathing like it wants to.

Seems to me from the pictures that the JL intake lets anyone that runs the KB to take advantage of the KB's full volumetric efficiency and capability

I'm sure I will see one soon.

Great job JL.

Didn't Kenne Bell show a big gain in the MM&FF magazine a couple of years ago?

Can you post a link? I had always thought there were no real significant gains...

So, with that thinking the smaller the opening the better? What if we stuck a pin hole size attachment on the end of the hose?

 

As far as KB showing a big gain with their throttle body, I honestly dont know anything about that, so I wouldnt want to assume anything.

Upper intake extrude honing does result in gains and that has been proven time and time again, at the track and on the dyno, not huge numbers mind you, but signifigant enough numbers that exceed any posted numbers from just a tbody.

No, a pin hole size attachment isnt better, what your failing to understand, and of course you will argue, is that the combination of tools that are given to you with the vacumm cleaner have been tested, and yes, calibrated to the efficiency of the unit, it doesnt hurt the vacumm if you put on that small attachment that reaches into corners because its been designed that way. Same with the tbody of the Lightning.

Hope this helps.

Where those tests conducted with a stock unported TB then with an aftermarket or ported TB?

So which TB has the KenneBell blower been calibrated for?

 

Sal, I agree to have a logical discussion like adults. I agree with everything you have said 100% except that you are assuming the TB is the restriction. Im saying that based on Flow Numbers provided by SVO, ACCUFAB,Billetflow it seems that the TB is not the restriction, its the volume that can flow thru the stock intake thats is the restriction. Just like bigger doesnt always mean better(Portsize) on heads, air speed does mean more air. It is possible to move more volume at a slower air speed. Another example besides my air compressor example would be a Outlaw car, if you look at alot of these S/C and Turbo cars they have a bigger feed into into the Cooler than the TB. Just like you said, I am not expert either, Im just baseing my thoughts on these examples. It would be nice if JLP or somebody did give us a explaination instead of us trying to figure it out.


Easter- Its obvious that you have a extreme dislike for KB and Sal is your tuner, this post was nothing more than sarcasim and like Grey03 said, no matter what your told your going to feel different.

 

What? I don't understand how you come up with that load of crap. PSP, JDM, JLP have all tuned my truck and I currently have chips from all of them. I plan on purchasing an SCT tuner in the next few weeks so that I am not dependant on any of them.

It think the quote above is pretty funny by itself, but look on page 292 from the October 2002 Truckin' magazine and they claim 17-20 hp with the accufab over the factory TB.

 

Just based on things Ive read on many of the boards, Be a man and just say what you feel.

Here are 2 to refresh your memory, you flat out dislike the performance your KB has given you as well as the customer service you have received. I will admit you have had problems with KB, I just wish you wouldnt beat around the bush like you are in this thread. If you think that Novi is gonna perform anywhere close to the way you KB does, your in for a hard let down. The Novi is a 1/4 mile Blower and will not perform anywhere close to what a roots will on the street. Might I suggest some 4.1 gears and a very loose convertor, and as you know, I speak from experience.

 

No where in those threads will you see me complain about KB warranty service. You won't even see me saying that the KB is a POS blower.




Granted I think any big centrifical or turbo is better.
