Halltech

Stage 1 package includes Halltech's ULZ Super Beeline™ Ram Air Package consisting of the Halltech SBCF112CKN™ Intake system, FAST intake manifold, and the Nick Williams 102mm throttle body. Plus you get the Pfadt Race Engineering Equal Length Tri-Y Long Tube Header, and mid pipe with cats. Tuning is required with this package.

Halltech's new SBCF112CKN ram air induction features our all new carbon fiber intake system, with our new carbon fiber sandwich of DuPont™ Nomex® 455 (NOMEX® & Kevlar® as our heat insulator), deflecting engine bay heat soak thereby reducing IATs. Testing has shown a significant insulation effect using this fire retardant insulator between layers of our show carbon fiber on the bridge and Beehive™ heat shield. The FAST intake does not come painted. Fuel rails shown are not included.

The ULZ Stage 1 gives you the same intake components Halltech is using on the ULZ700. The Super Bee ram air induction, LSXR intake manifold, and Williams Performance 102mm throttle body. At last month's Katech dyno test, we recently out-powered the Harrop ITB intake manifold on the chassis dyno by .3 RWHP. These tests were done without confirmatory bias: In fact just the opposite. Jason from Katech and I bet on how much more power we would see with the Harrop. We wanted to see big numbers for our ULZ project goals; all Harrop pulls were done the open hood, with no plenum or filtration to interfere with the individual velocity stacks. 5 different tunes were tried including the tune from Harrop.. A fresh tank of MI e85 was pumped hours before the dyno pulls on the Harrop, Halltech used leftover winter grade e70 from last year. The Halltech ULZ air induction did not have use of its ram air feature being stationary on the dyno. Also, with the Beehive in place, it is equivalent to the hood being closed, since only low speed air into the front NACA duct (modified for 300% more dynamic airflow), from a low speed large non-directional fan is all that was fed to the AIS. The Halltech first pull was 610 RWHP, but it was cut short due to some knock sensor activity. The comparitive A-B chassis dyno is attached. *Please note: The 606.4 RWHP is not our claim with this package. Those numbers are with a full Track Attack Katech 429 motor on e85, 13.2:1 CR, fully ported heads, the Kavorka cam (my nickname), and larger injectors.

The Halltech Super Bee Package has the world record e.t. of 9.97@137.74mph (stock ported throttle body), and now the new Katech chassis dyno record of 606.4 RWHP/535lbs-ft torque for a stock cid motor, and is only 11 RWHP short of their all time 617 RWHP 501 cid record. Halltech's ULZ intake system is 4 lbs lighter than stock. Halltech's remote emailTune® programming is available for those not able to find a Halltech tuner.

jim when are you coming out with your cam?

Excellent idea... it's obvious now that you bring it up, but regardless of what type of uninsulated intake tube you have it is going to get heat soaked in the engine compartment and the intake air will get warmed up just passing thru it (like the a/c vents when the car has been sitting out in the sun), even if the outside air is actually cool to start with.

We will have a video today of our first CF112 made with this sandwich meat. The other day we did preliminary testing with a hair drier on full heat. My bare hand inside the bridge on the bottom, the hair drier within a couple inches of the bottom with only a few layers of carbon fiber and one layer of Nomex®. Laser thermometer surface temp on the outside was 150F, my hand still able to hold the inner surface of the bridge. The new material with have Kevlar® and Nomex® together.

Obviously, not real scientific, but we'll get a thermocoupler for the surface and get more accurate numbers.

Even our current carbon fiber intake only sees +9 degrees rise in IATs sitting at an idle for 75 seconds (the average stop light time). We are hoping to get the increase down to just a few degrees.

The issue is ambient vs. IAT. Our Super Bee intake system keeps OATs and IATs in virtual parity when moving, through the NACA duct. Ours is opened up substantially for better flow, and no penalty from surging.

Stopping is what increases IATs due to heat soak. Our headers are not coated, so we have a penalty there.

The sweet deal here is we get to improve IATs without covering up the Show Quality Carbon Fiber. The Beehive heat shield can have this option done as well, but is not included in the pricing, just the bridge.

You mean the cam in our ULZ right now? It is available from Katech or you can order it from us.
