Halltech's Stinger-RZ GEN 2 RECORD TORQUE DYNO PULL
You have all seen the +45 to 55 RWHP numbers generated by our Stinger-RZ GEN2, we now have over 14 dynos from independent shops, some that have never in the past done business with Halltech, that have hit between 44 and 54 RWHP on the chassis dyno. One engine dyno was +60.
This is from Scoggin-Dickey, Halltech's largest GM Chevrolet dealer, and this is their third dyno done with our plastic Stinger-RZ GEN2. There first dyno was +48 RWHP.
Unfortunately they did not do a baseline pull for their customer Mike P. but his final numbers match the recent pulls done by Andy at A&A Corvette in Oxnard, CA. I will post Andy's pull first for reference and note the Halltech intake only pull before and after. The after is within .5% of Mike's numbers. Remember, A8s have a 20% DLL vs. around 12%-15% for the M7.
This would make Mike's numbers around 48 RWHP using the same base. That is not unusual and really not a valid way of showing dyno numbers, but look at the TORQUE!!! 660 lb-ft. This is an A8 on 91 Octane. The DLL for an automatic is 20%. Do the math.
Andy's pulls on a A8 on 91 Octane:
+44 RWHP/ 41 lb-ft.
Now here is Mike's pull with an A8, with 1200 miles, on 91 Octane:
All three dynos are with the Halltech Stinger-RZ, and no tuning or any other mod. One single bolt on.
In case you think that Andy's dyno show's low pulls, here is a second A8 done a few days before the first one above:
+50 RWHP/ 43 lb-ft.
I was told by all dyno shops that our intake makes boost over stock, it also causes the throttle body to open to 100% vs. 35% which is what some tuners go after with tuning according to Geiger Cars. Air fuel ratio is dead nuts on the best power (safe power) and the parasitic power loss to vacuum is recouped with our intake as well.
One more point. The high vacuum signal of the stock intake, caused by extreme restriction to flow is part of the problem on the track with overheating in my thinking. When the SC has to fight against the huge parasitic loss caused by the extra vacuum signal (remember the filter used by GM is the same exact filter and airbox as the LT1) would cause much of the overheating, the way the AC does, only much more.

How do we explain why the stock intake is so awful.
This much power from just an intake, is unprecedented isnt it?
The filter is not restrictive to flow on the stock LT1, and our intake only makes +14 to +19 on that platform.
Imagine the pulleys and rotors that the engine turns at 20,000 rpm. Restricting the flow through the LT1 filter and small airbox assy, creates tremendous heat just to run the supercharger under extreme vacuum. Why do we turn off the AC when we race? Loss of HP, and additional heat from parasitic loss. Horsepower lost from a supercharger is around 20%. So it takes around 800 HP to net 640 hp with a supercharger. It is called efficiency. Some of the newer Eatons consume less power than the older versions.
Unprecedented and totally unexpected. I would love to take credit for all of this, but I designed the intake with laminar airflow in mind, and was hoping for 25 HP. Katech was the first dyno our Alpha prototype, and busted their seams with +28 RWHP. Just a touch of a tune bumped it to 35+. That prototype was way too lean, which we corrected right away, and shipped one to Geiger Cars in Germany, and one to Smokey's dyno in Ohio. Geiger went ballistic with +60 PS, or 59 HP on their engine dyno. No tuning. Smokey's dyno pounded out +51.4 RWHP on their first Z06. Keizer tuning in MAF blazed 53 RWHP on their dyno. The numbers keep coming in.
We've been told that our intake makes more slightly more hp than the stock intake without the filters installed, and more boost that the stock intake with a small undersize pulley. Lots of surprises. If you want to save $600, you can take out your stock filter and run that way.
Water temps for our Z06 driven by professional Cadillac Racing driver Andy Pilgrim, Jason Harding and Jimmy Painter came into the pits with 218F water temps, and none of the other too cars at the track with our intake overheated.
When are the Stinger RZ Z06 Gen 2's going to be available. I check back fairly regularly on your website, but they are always Out of Stock.
We have 20 in stock, but 7 backorders. We have sold 250 since March, so stock is near impossible. We're selling around 5 to 6 per day.
We have pleanty of dry filters and high flow filters. Order the high flow filter (no tuning needed) and for $39.00 we'll add the dry filter to your order.
Order now and it will go out this coming week. The Gen 2. Hand ported velocity stack, blended into the intake tube.

I don't even have the car yet but I want this. I'm a little confused at the difference in performance between the carbon fiber unit, plastic unit and the filter options. Your "high flow" filter sounds like it's max performance, but isn't this the one that does NOT require a tune? If so, is it the dry filter that actually offers max performance and works better WITH a tune?
Ultimately, I will add exhaust and tune the vehicle, so I'm looking to get the unit and filter that will allow maximum airflow/HP. However, at first I just want to bolt it on and enjoy it for a while, prior to doing any tuning. What is your recommendation?
I am in the same boat as rectifyer2000 (picking up my car on Monday and just want to enjoy it with no tuning for awhile), but I know I want two things before I purchase so I get the right unit. (1) You state "no tune" here for the high/super flow 689 that comes with the Stinger Z Gen 2. So technically it seems like neither one (high/super/689 or the BloodOrange/dry/589) needs a tune. Is this correct? If so, then would the only real reason to run the dry element purely because of very occasional maintenance to oil the high/super/689 filter? I appreciate the $39 offer, but no need to get it if this is merely a question of occasional maintenance. (2) Aside from the great looks, is the only other benefit of the original Carbon Fiber unit its heat soak protection? Furthermore, is it even available anymore (it appears to have disappeared from your website)?

I WANT TO ORDER ONE in carbon fiber both filters, I only see the plastic one on line help PLEASE.
We have discontinued all carbon fiber products at this time. We will probably have the CKNZ back this fall.
The high flow filter has always been the filter that comes with the Stinger-RZ. All testing, dynos, etc. have been done with that filter. The dry filter is slightly more efficient at the cost of a few horsepower.
We will have a special going today on our website that offers the second filter for $49.00 when purchased along with the Stinger-RZ.
