Judging by the numbers, it would appear that this run was done with our TRIC Ram Air system and a large fan. Normally, we see +50 rwhp or so. There was another dyno done that showed over 100 RWHP, but the customer did not believe the numbers so he did not want them published.
The TRIC WORKS! We have seen track results of +3 mph and -.2 e.t. in the quarter adding the TRIC to our Stinger RZ. I will try to find that today and post here.

Can you show us the before and after lambda and manifold pressure?
Lambda is posted after the Smokey's dyno (air fuel ratio)
Our Stinger RZ adds around 1 PSI to the stock setup (10.1-10.5 PSI) I don't know where that HP file is, but here is the results with our TRIC Ram air onboard:
Halltech TRIC RAM AIR INSTALLED
12.1 PSI - This is our C7 Z06 in which we installed the Stinger RZ in plastic, and carbon fiber for testing the optional TRIC RAM Air system. 12.1 PSI was the result in 3rd gear. No additional boost in 4th gear.

Looks like the stock run was in Cat Over Temp Mode... 10.3 AFR is pretty much a dead giveaway. Explains why the WHP was so low. Not saying the Halltech didn’t add power, but getting a stock run without COT on would have been apples to apples.

If you look at your Datalog it should the manifold is at 176KPA. Subtract 100KPA if the air was perfect and you are left with 76 KPA which is about 11.01 PSI of boost. HP tuners does not read the proper PSI with the PID you have selected. You have to use the math function of Manifold KPA(hi res) minus Baro KPA and then convert to PSI for proper boost levels. The newest version of HP Tuners (Anything past 4.2) now has this math PID pre built so you just need to monitor the hi res PID's to display boost.
Regardless of anything though, if you see the gains at the track, that is where the real truth is. I appreciate sharing the lambda example. The Halltech does lean out the AFR as expected, likely due to the additional airflow and the reduction in velocity across the MAF, but this is no secret either. Seems like a great mod for someone that just wants an intake without a tune and for someone that is willing to tune for it along with other mods.

We are at 880 ft. hear in Wisconsin.
Hope this helps. HP Tuners showed around 14.4 PSI on the day we did this testing.

I think you will find that the Z almost ALWAYS goes into COT, just the nature of the beast, until you tune the COT off. Datalog yours, see if I'm telling the truth. Mine always did (before tune) and even at 10.X: 1 A/F it made 40 + more RWHP than stock with the Halltech.

Appreciate the response. So you're saying that you made almost 5psi more than stock at 888 feet above sea level with the Halltech RZ? I still don't understand. If the Baro was 101KPA and the Datalog shows 176KPA in the manifold then there was 75 KPA of positive pressure. I know you were at 888 feet but how are you suggesting this works into the equation to calculate boost pressure at 14.4 PSI? Or are the pictures you posted not related to the 14.4 PIS datalog? Just trying to understand here.

No. COT was active every time I went WOT until I turned it off with a HPTuners tune. The Halltech CAI made 45 SAE RWHP more than stock, apples to apples, COT was active both times.

How much power do you gain by going from a run with cot to one without.

Maybe I’m not getting my point out correctly. The stock run obviously had COT active judging from the pig rich AFR. Simply adding a Halltech did not tune out COT, but it’s obvious that COT had not kicked in during the Halltech run. Not apples to apples IMO. And there is no way a CAI leaned out a WOT run nearly 2 full points...lol
