John's intakes are the best on the market-hands down.I've used them all-everyone just builds a cookie cutter intake that will fit the car.John makes an intake that works on your engine-and hopefully will fit the car.He hates the words "i have to fit it under the hood"

It's interesting that no one publishes their intake dimensions of specifications. Intake runner length, taper degree or plenum volume although I can honestly say that dealing with John Beck is a real pleasure. give him as much information related to your build and goals and he will build you a perfect match. I can attest to that from firsthand experience.

how would this be possible when every intake is custom and every engine requires something different?

And the only way to say an intake is optimum for any setup, would be to build and dyno multiple intakes.

Not exactly a cheap option for anyone. So I'd say all designs are built to fit within the space provided.

Although generally speaking if you can maintain long runners without affecting flow, all the better. Likewise maintaining adequate plenum volume.

But space will always compromise these things.

Very true...Duh...

Bottom line is. As long as whomever is building the intake is listening and has the experience, you'll be in good hands.

All the mentioned intakes have done the deed. Some better or worse than others. The Brass Tax is the each engine builder has the intakes they like and push, that they have used with good results, ect, ect.... They all have their place in the market. You just gotta look at what you are building and what fits with in your means, then make your decision.

I've been impressed with the factory LS7 intake. I don't use egt data just old school sparkplug reading.....looks pretty good at 1100rwhp

Some data from Marcella Intake Manifold without any correction from big stuff 3, this was taken about 5 second in...
(1)1700
(3)1705
(5)1685
(7)1680

(2)1716
(4)1705
(6)1710
(8)1719

We have data from multiple engines with the Marcella intake and its proven to work. Sure there are other brands out there but does anyone have unbiased data available for the public?

There is little boubt the OE intakes have a lot od design and testing behind them, and they do work superbly. For the money, little beats them ( mostly since they are free on the engine they come with )

That's a very good question Phil. I would love to flow my Beck Intake and publish the numbers here. How did you do it with your BS3? I might just drop mine off at my engine builder and let them put it on their flow bench.

Shawn @ VA Speed

iTrader: (3)

those are egt numbers not flow numbers.you can see the variance in the egt's are around 40deg at 1700 deg.that is about 2.5% difference.

barkingspud

OK. I didn't know Phil had EGT probes. This might be a really basic question but how do EGT's correlate to flow in CFM? or, are we just looking at the variance between the individual runners?

Hard to argue with those numbers. A 2.5% spread is awesome. Thanks for the data Phil!

the big kahuna

how about that 102 fast intake I was told that it can Handel more boost then the old ones. how much can the 102 fast go??

355TurboLT1

iTrader: (11)

They are still composite and there is the fear that higher boost(lets say 25psi or so) they may flex or crack. The sheetmetal intakes open up almost endless options. They are taylored to you setup. I'm pretty much sold on the Marcella. I don't want to drop a $1,000 on a FAST 102 only to have issues.

I dont like that design. When the throttleblade is open, 30%+ of the throttle opening is obstructed by the deck.

You ought to see down the throat of a Wilson billet.

True but it provides an airfoil to increase airflow velocity. I have been thinking of having John fab another top for it with a carb style flange for a 4500 style TB on the top. I think that will even up the airflow a bit.

i must have the idea of FI all wrong in my head.
