Halltech

Let Gary Hillen decide for you. World Record Holder for the quickest and fastest naturally aspirated "BOLT ON ONLY" Z06 in the World. This motor is stock except for the Halltech Super Bee MF103, ported stock throttle body, and FAST LSXR intake manifold. It is, tuned of course, has headers and some weight reduction, and a 4.10 gear with slicks, but lets concentrate on the intake tract only.

The Halltech Super Bee MF103 has a 102.4mm read arear at the MAF and has a larger plenum volume than the former champ, the Killer Bee II, but 20%. It has a girth with 1" larger circumference and accelerates the massive air volume at peak velocity at the 105mm outlet.



Using the stock 90mm throttle body, port blended or not is the point of flow restriction, albeit not by much. Ported throttle body is incorrect terminology for cleaning up the entrance of the stock throttle body, since real porting would involve enlarging the 90mm throttle blade. Those that use the Nick Williams throttle body are getting 101.9mm vs. 90mm and even our 429 650 HP alky motor only benefits 4 HP on the Katech dyno.


The FAST LSXR is 99.6mm, not 102, so when you look at restriction to flow, the MF103 will never be that point.

When the Lingenfelter, Callaway, or VR intakes beat our records, we'll quit beating our chest. (until the next win)

What about idle quality, long term fuel trims? Check out our prototype testing back when we first started the plastic version of the Super Bee (called it Killer Bee back then):

The MF103 makes the stock intake look like it was made by amateurs:

Soon the Halltech intake will also sit atop the LS3 internal mod category. . .

Thumbs up to Jim and crew

Craigster05

Great intake for certain....all we need now is a spring time group purchase..or at least a Father's Day sale

Halltech

Of this I am certain. That will give Halltech all the records for NA 6 speed.

Watch out for RPM Transmissions. They have a Z06 with major power and CR running E85. TJ expects to break into the 9.8 range. He runs the SBCF112.

How is installation on this? Do you have to cut anything?

JUIC3D

Fairly painless. I can remove/install mine start to finish in about 5 minutes now. Once you figure out how to get the beehive in, its cake.

Voodoo GS

Does that mean you dont have to cut anything?

JUIC3D

Yes and no. Halltech does suggest/say you can notch the radiator shroud to allow fresh air into the filter but I don't think it's required. There are descriptions on their website as well. I used a kitchen knife to make the cuts and I consistently see IATs +3 ambient

Voodoo GS

Thanks, though I don't know what IATs +3 ambient means.

JUIC3D

Oh. IAT stands for Intake Air temperature. That is, the degrees in Fahrenheit of the air that the motor is breathing in. The stock tune starts to pull timing when IATs reach 86* and pulls as much as 8-10* the higher the intake air gets.

The Halltech intake design places the maf sensor(which includes the IAT sensor) forward of the engine bay and out of the warm air that is a result of the motor running. Moving the maf forward and shielding it with the beehive, keeps unwanted warm air at bay and when you notch the radiator shroud, you are provided a nice stream of cool ambient air. Given that there will always be residual heat coming from the motor, you wont' see IATs be exactly the same as ambient, but I log my motor regularly and unless I'm sitting in stop/go traffic, my IATs stay right around +3 of ambient. If it's 75* on my a/c readout, I'll see 78* on my IAT when I scan.


Hope that makes sense.

Voodoo GS

Makes perfect sense. Thanks. Does the intake come with an extension for the MAF?

JUIC3D

Absolutely. It comes with everything you need for install

C7/Z06 Man

Heres a challenge for Halltech, install your CAI on a "totally" stock Grand Sport and see what kind of ET it runs. Please let us know before the track visit and then report after.

My LS3 (430HP) A6 GS ran a 12.01 @ 117 MPH using a "modified" Z06 (no sound box on Z06) OEM assembly with the factory paper filter to make a "home made" CAI.

Other than the home made CAI the car was completely stock at the time. The old 12.01 time slip with info located in 1/4 mile section.

Here is the suggested cuts for cooler air:
