For Wifey's birthday I ordered her the Halltech carbon-fiber fuel rail covers and the Halltech carbon-fiber Tunnel Ram intake system. I did the installation and want to share my experience here...

Halltech isn't the cheaply priced but it isn't cheap quality either. When ordering, Jim was very helpful and honest about all his products' pros and cons. Everything was shipped complete and on time as promised! Again, the finished quality of the carbon fiber was flawless and upon installation I found everything to fit perfectly into place.

F.R.C.s: just required using the clips from the original and they went right on. As far as I found through research they're the only true c/f rail covers available. Definately are worth the $

Tunnel Ram: took more time to remove the stock system than to assemble the Halltech. I went with the c/f because it tests better for air flow and looks awesome too. While in there I cut the screen from my MAF (she's an '01), thanks to all the forum threads for pursuading me to do it! I did the battery disconnect... and took a ride for @ 40 miles. Oh, my head! Suffice to say that this engine now growls with the authority it deserves. From 3,000 and up at over 1/2 throttle it sounds like the secondaries of my 1050 Dominator/454 set up from years ago did. Big, Bad-Azz air induction. The car is unmistakeably more powerful and when I punch it in 1st at 20mph the car breaks loose now.

If you've been considering purchasing this mod, wait no longer, it's worth every nickle! Instant gratification!


:cheers:

 

Jim knocked a home run with his new Trap system... we have dyno proven numbers to back it up.

That is one sweet looking engine compartment :yesnod:

:cheers:

 

:cool: :cheers:

 

His CF airbridges are definitely a thing of beauty. I have one of his earlier bridges and it looks incredible. I can't imagine how much better the newer ones look since he's got some experience under his belt now.

BTW....Jim Hall....if you see this thread, your new black CF bridge. What shade of black is it? I mean does it have more of a black/charcoal appearance? I'm interested in maybe picking one up but the pics I see floating around don't show much detail. The one I have now is more of a brownish shade and I think more of a true black or even slightly charcoal would look killer (It's an older T1 era bridge)

It depends on the light. They are definately darker and more toward a charcoal color.

The difference is our carbon fiber process is to autoclave everything. This is much more costly than just oven curing. Each time the autoclave (20'X10') is cranked up to 290-degrees and filled with N, it costs around $900.00.



Here is the capability of the shop we use:

Composite Department:
7000 square ft. Composite Fabrication facility, includes a 2000 square ft., controlled environmental Prepeg lamination area
200psi / 800deg. F capable, electrically fired, Nitrogen purged Autoclave, 9ft. / 6in. Diameter X 18ft. Long.
425deg F capable, gas fired Oven 9ft. wide X 10ft. long x 7ft. high.
600deg F capable, electrically fired Oven, 3ft. X 3ft. X 3ft.
Walk-in freezer, 8ft. X12ft.
Calcomp 60in. X 44in. Digitizing board / AutoCAD / Digitizing software
GGT / Cutting Edge DCS 2500 Computer controlled cutting system, 24ft. X 5ft.
In-ground 10ft. X 20ft. Surface Plate / Styling Bridge.
Table to 5ft. X 10ft. Surface Plate.
Wichitech CR-1 Composite Field Repair System
V.A.R.T.M. - Vacuum assisted resin transfer machine.

The result:





We now have a new color called Glossy Pomegranate Red. This color requires hand buffing and is more expensive:

Hi Sun King -

I agree 100% with all of your comments -

The TRAP made a very noticeable improvement on my 2002 Z06 - and it is the best looking system IMO (I have a red CF TRAP).

I also think the exhaust has more bark to go along with the "four barrel" sound.

Jim is a great guy to deal with and a real asset to the CorvetteForum.

:thumbs: :chevy :flag

best regards -

The Trap might be the best intake on the market. :yesnod:
Halltechs' CF fuel rail covers are the best in the market. :smash: :smash: :cool: :thumbs: :cheers:

 

For those of you that have a TRAP........how hard is it to get at the filter to clean it once it is installed?

 

.Not very hard at all, you just take out a the couple of screws on the bottom of the bumper and undo the filter from the tube.. not bad at all except that you have to get the front of the car in the air to have access.

 

Hi Ruby6spd -


:iagree:

best regards -

That's one beautiful engine bay. Halltech's stuff is way to pricey for me, but it looks and performs great! I'm happy with my vortex, and I sure noticed a great gain when I installed it. Just look at the stock '01 box... it sucks :steering:

 

How did you mount the MAT sensor? Did you have to drill, hole supplied, or mount in the coupler? I still have the stock air bridge and coupler and am interested in changing.

 

The sysetm is totally compatable out of the box, no drilling/cutting required. The Halltech simply "plugs in". The only modification I did was to cut the screen from my stock '01 MAF. You will not be disappointed :thumbs:

COBRA 48: Maybe, Santa would hook you up :jester

 

Your engine compartment looks really nice! :cheers: I put the TRAP on mine and it made a difference over the old T1 system that I had on there. I also had the TRIC, and I really liked that, but to me, the TRAP is the best intake on the market (nothing against the VaraRam, this is just my opinion). I think that you made a great choice! :thumbs: By the way, Happy Birthday to your wife. Those were GREAT presents that you got her! :yesnod:

 

Tech Tip:

Removing the laminar airflow MAF screen:

There is some confusion on the forum regarding this issue, so I'll attempt to clarify some facts.

The mass airflow sensor is just a sensor. It is not, and cannot be made a high performance modification.



These are actual flowbench results of the stock airbox, with and without the laminar flow screen, and with our TRAP, with and without the screen.

By just removing the screen on an LS1 you take a chance of tripping lean codes.

What is a lean code? The MAF is just a meter (sensor). It reports the value of the mass of air to the PCM. The injector pulse width is then regulated by preset values for each frequency (the MAF reports in frequency).

The pulse width or time the injector is open may or may not provide precise closed loop fuel trims at the 14.7:1 stoichiometric values which governs closed loop.

Enter the O2 (lambda) sensors. The first pair of sensors look at the exhaust gases and report the true values of the combustion process back to the short term O2 trims. You car then tweeks the a/f ratio until each fuel cell adjusts to 14.7:1. Over a period of time the trims settle down to a perfect burn, and the delta between MAF reported airflow, and the actual reported at the O2s records as Long Term Fuel Trims.

GM, has build in a +24% threshold which is called "authority". If your O2 sensors need to add more pulse width than the MAF is reporting, to any fuel cell beyond 23%, a P0171 and or P0174 lean code will trip.

It is easy to program these codes out if you own a copy of LS1 Edit.

You must own a 97-2000 model. We drill the IAT hole in the same location as stock. You simply move the sensor and grommet to the new Tunnel Ram Air Bridge.

Here is a list of our dealers. Most support this forum:

This was only thing I wanted. Thank you my husband for getting it. :party:

 

I was under my husband profile in error.

 

Jim that stuff is gorgeous!! :yesnod: :yesnod: :yesnod:

 

Thanks Lager99.

Wait until you see what we have coming for the Mil Yellow and Electron Blue.

Here is our latest carbon fiber Stinger set:



Made from secret ingredients like nickle threads and carbon fiber. This picture does not do these justice. Only in person.
