Default Halltech LS2 to LS7 Intake Conversion

Yesterday, we successfully converted the C6 LS2 from the stock intake to the C6Z06 LS7 Intake system.

We also ran our new Killer Bee AAIS for the C6 on this car.

It took a day of tuning to recalibrate the new Hitachi MAF sensor with the proper code to dial in all of the Long Term Fuel Trims, but when finished the results were spectacular.

Our customer did not want to take the Killer Bee off and go back to our older C6 STinger SSM system, so we compromised and installed the stock LS7 AIS in its place.

The new Halltech 100mm Delrin MAF comes with the Hitachi Probe MAF sensor installed and brings an additional airflow to the induction system.



Our all new HAL1000 filter is smaller than the SSM filter (14" vs 20") but features a full radius ASME horn style flange for high velocity through the airbridge. The newly designed airbridge will be available in Black or Z06 Red to match the LS7 covers when used on the Z06.

Other than the color, the Killer Bee AAIS will be identical to the Z06 Killer Bee AAIS. It will come with the MAF sensor, and conversion wire harness.

Reprogramming is not an option. It is mandatory, since the new probe MAF requires different calibration altogether to work.

For those that already have LS2 Edit or our EMAILTUNE, this recalibration table will be available free of charge by email, when purchasing the Killer Bee AAIS.

We have only 50 being made for May delivery at this time. Our first run of Killer Bees will be to fill preorders for the Z06 crowd, and will be in Z06 Red. If the Red is ok, you can order and get delivery by May 10th.

Our EMAILTUNE is the easiest way to recalibrate the MAF code. Our EMAILTUNE is $999.00, but includes the $550.00 LS2Edit hardware, software, license (single) and 2 programs from Jim Hall.

We can tune for the Killer Bee, and or the LS7 AIS if you prefer to run GM equipment. It is my understanding that the new LS3 will have an LS7 style intake from the factory, with the new Hitachi Probe MAF for 2008.

You can get that same performance now.

OK C6 Corvette Fans!!!!!

I'm the one that tried the new set up and it was ausome! Smoother, more responsive, better sounding, and really brought the LS2 alive!

We reprogrammed it and have a little more to do, but you will know the difference! We don't have a good DYNO around here for before and after, but you can sure tell the difference. I had Jim's LS2 Tune and intake, LG Long Tube Headers, B&B Route 66, and a few other things before!

Jim made it run much better, but he who giveth, taketh away! We were using the Proto Type and Jim said I had to take it off. I do have the regular C6 ZO6 intake with the LS7 Probe and it is better than what I had, but not better than what is coming! Trust me!

Can't wait for my next Quickie Jim!

No numbers yet, but our C6 Stinger SSM put an additional 11 RWHP/8 ft. lbs torque on his car two years ago.

The MAF alone will outflow the stock C6 MAF by double. The new HAL1000 filter is less restrictive than the SSM filter even though it is smaller. The ASME Horn inlet smooths the airflow ingress which allow much lower restriction at all rpms.

The biggest change next to more power, is the smoothness, with no surging whatsoever.

This intake alone should be worth 15 RWHP over stock and around 22 to 24 with proper air fuel ratios.

Two footnotes. Jim did not have our new HAL1000 filter onboard, since they are not finished. We also set his timing to the Z06 timing tables, with 2 more degrees on the top.

ZERO KNOCK RETARD. We ran 13:1 air fuel ratio (Commanded PE/RPM) which should be dead nuts on with a wideband at the collector, since the Long Term Fuel trims were near perfect.

Once we get the production filter onboard, I will finish the program, that will be dialed in perfectly for the C6. For now, Jim will have to be satisfied with the extra 7 RWHP that comes with the LS7 AIS (Air intake system).

Jim Hall

We tested the MAF calculated airflow at 394 g/s with our off the shelf filter. It should come in at over 400 g/s with the HAL1000

So for the $1k you get a new CAI, a new MAF and the tune for roughly 30 rear wheel HP?

Please dont take this the wrong way but were getting close to this for less money with a Vararam.

Iam interested just a little cornfused

Thanks

Interested in seeing the results. I've long wondered about what gains could be had by using the ZO6 airbridge. Gotta respect that Halltech is doing this research.

As far as I know, we are the only company offering the conversion to the LS7 MAF sensor.

This MAF requires retuning the ECM code to work. We do not have dyno numbers at this time.

Some folks in the market for an intake right now, might not be satisfied with speculative marketing rather than numbers. I have not seen the VR numbers and never compare our products to the competition. We instead compare to stock.

I can tell you that NO intake will outflow our Killer Bee. Dyno numbers are all over the map when done by different shops, different days, etc. You probably know the drill. We deal in real numbers that are repeatable and real. We want our customers to be able to repeat our claims when they come out.

How are we coming Jim!

My C6 with the ZO6 Probe is working great! Tune is fantastic. Much smoother and more response, let alone more power!

It's finally getting warm in Wisconsin, and I'm ready as soon as you are!

It all sounds good but before I spent this kind of money on a system like this I would need proof it works either at the track or on the dyno and more than one car, etc...

I had another brand CAI on my 05 then switched to brand B CAI and with no other changes got another .15 sec in the qtr mile. This is proof it worked better than the first makers CAI. If you dont even have results on yours how can you say its better than everything else out there? Iam sorry but at this point it sounds like hype.At this time I will let someone else spend the dough and wait until I see results at the track and on the dyno. I hope the results are good, I like using stock GM parts as much as possible, and its tough to argue with the pretty good rep you guys have. I will be keeping an eye out for more guys with this setup.
Thanks

I agree though a dyno numbers don't always equate to tracks gains. I had a Halltech cai (stinger) and though good quality, never had any issues, they claim dyno gains but there were no gains at the track. I swap to Vararam.....instant and consistent gains.

The new LS3 for 2008 is likely to have the LS7 style MAF and hardware. Same restrictive Donaldson PowerCore filter however.

We had Donaldson test our present C6 Stinger SSM vs. Stock vs LS7 AIS January of 2006, and found that the LS7 AIS had less restriction than our C6 SSM, by a small amount, but this gave us pause for reflection.




http://www.corvettels7.com/Halltech_test_report.pdf

We decided to use the stock LS7 AIS and incorporate our F1P30Z Foamicomb Filter for Racing and Dyno time, and found that it added a full 8 HP on the Katech Engine dyno. taking the stock filter out altogether is 11 HP, which is a recipe for disaster.

Earlier this year we decided to pull out all the stops and engineer our ultimate induction system for the LS7 called the Killer Bee. It has approximately 50% less restriction at 850 cfm than the LS7 AIS, and utillizes the LS7 style probe MAF sensor. The stock Delphi MAF is the highest area of restriction in the C6 induction system.

GM told us that even the LS3 style intake makes 5 more HP all by itself vs the stock C6 induction currently onboard the C6.

I appreciate folks wanting to wait for the numbers. They'll be coming.

We don't expect folks to order this unit blindly. We do have 25 pending orders from the Z06 crowd, since they already know our reputation for honesty in our hp numbers. If we say 12 RWHP, that's what you can expect to see on your car.

Just to give you an idea of how hard it is to make HP on the LS7. Here is a PowerCore vs PowerCore filter that we had Donaldson make for Halltech called the LS900.



This filter made only 2 RWHP/ 2 ft. lbs torque on the chassis dyno at Donaldson's dyno in Anoka, MN.

It made 2HP/2Ft.lbs TQ on the engine dyno at Katech:

http://www.corvettels7.com/Halltech ...Comparison.pdf

Tested also by GM High Tech and Performance MAG:

http://www.corvettels7.com/halltech_LS900.html

Not much to write home about, but GM asked for us to send this filter to the Milton Proving Grounds earlier this year for a test vehicle they will be releasing soon. Wonder what that is?

Jim

Jim, great job! Your new inlet flows great. Where does it pick up the inlet air? Is this a cold air inlet? Do you have to cut the radiator shroud?

Excellent. All the little things can certainly add up to good cumulative gains. Its also good to know that it can yield more power on a higher hp combo. When you mind the details you can leave the competition scratching their heads

Just a footnote. Anyone with a C6 that is looking for the "stock look", and no warranty issues or CARB issues, can purchase the LS7 AIS from GM along with the new High Flow Hitachi Probe MAF sensor, and Halltech can tune the ECM for $175.00, which includes the Halltech "Plug and Play" MAF conversion harness.

This tuning is just to change the MAF code needed to run the new style MAF, and does not include power tuning. We can power tune air fuel ratios, torque management, and timing changes, CAGS defeat, top speed limiter, COTP modification, for max torque and performance for an extra $100.00.

Total package tuning $275.00. You pay the freight, but we promise to do the tuning same day, and return it the same day.

For best results, send the ECM FedEx Next Day Air, and include a return NDA label back to you.

Send it to Halltech Systems, LLC. 37602 Wildwood Lane, Oconomowoc, WI 53066. Email your instructions to jim@CorvetteLS7.com

This is what is on my 2005 right now! I have had many flashes from Jim on the C6 MAF, with and without screen, C5 ZO6 MAF, and believe me my 2005 has never ran this good.

The C6 ZO6 Probe and Jim's tune make it a new car! Much more responsive, smoother, seems like more power, and even sounds better!

Maybe we can put together a package Jim! We can get the new LS7 AIS and ZO7 Probe, and you can send the tune! We'll check it out!

Why wait for 2008. This is what we have done already.

The Halltech LS7 AIS Conversion for the 2005-2007 C6 is here now.

6 HP of the new LS3 comes just from the intake.





Our New Killer Bee AAIS will add 12 to 14 RWHP to the C6.
