Chevy Perf CAI Dyno Results
 

Hey Guys new to the forum. Just bought a brand new 2019 Camaro 1SS A10. Only Options I have are NPP mufflers. My Goal was to see how fast you can make a 2019 Camaro ss run from the factory with warranty approved parts ie Chevy Performance CAI and such. Well with having a Chassis Dyno at my disposal I wanted to see what each change made a difference in power. I had been talking to Matt @ Wildhammer motorsports about the intake and what all I needed to give to the dealership for a fast and easy transaction when it came to them about flashing the updated tune for the chevy performance cai.



So I took my 400mi Stock 2019 Camaro ss and strapped it to my dyno to see what it put down stock. I did the pull in 6th gear instead of 7th its a little bit easier on the car lol for all the pulls. I have a Land&Sea Inertia Dyno and it reads a little on the happy side to read close to a dynojet but, no matter what the setting are the hp/tq gains/losses will be the same amount. It put down 425/407 tq.



I then took off the stock air intake and throttle body. I installed the supplied throttle body spacer that has a kind of duck tail on the bottom of the entry into the intake manifold. Im guessing its for tip in response and better distribution to the front two itake runners. I went on to install the whole cai intake setup and made sure to align all the dots and everything for the mass air flow sensor to read correctly. The whole install only took me about 1hr with me taking my time and using simple hand tools. Once done I took the car to my local dealer and they flashed the proper calibration for the intake. Was no problem when they had all the information they needed.



I got the car back to my shop and let it have a cooldown and strapped it back down onto the dyno and to see what the results were with the blue street filter. The results were pretty GREAT and right with what I was expecting. It made right at 16hp/16tq Peak to Peak and as much as 20hp/Tq in the meat of the curve. Now I attribute some of the gain from the leaner mixture with it being leaner up to about .3 to .6 AFR leaner until 5100 and it comes within .1-.2 AFR in the upper rpms where it made the 16hp difference.


I then Let the Car cooldown and swapped out the blue street filter to the Grey Race filter. After the car cooled down and I did a pull. It made the same peak numbers but, lost power in the lower rpms until about 4500 rpm where it matched the hp/tq. Now this is where things get a little interesting the Race filter leaned the mixture out a good bit in the lower rpm and im guessing thats where the hp/tq loss would be and im just using a tailpipe sniffer so the afr are probably slightly leaner in the lower rpms than what its actually reading but, this is also on a non load bearing dyno and with probably richen up some on the street/track and probably match in the lower rpm's and possibly make a 2-3 more hp in the upper rpms. The car is obviously seeing more airflow from the leaner afr so its safe to say that it will possibly make slightly more power.



Here in the next week or two I will be taking the car to the 1/4 mile to see what it will run in this summer heat and post all my results on the forum for everybody. If anyone has any questions or want me to show the data a different way feel free to ask:thumbup:.


The Dyno Graphs in order are

Bone stock vs chevy perf street filter
Street Filter vs Race filter
All three on the same graph


Thanks,
Jon

Nice

Here’s a pic of the car on the dyno.

Nice! How much did the dealer charge for a reflash?

How is the throttle response off-idle.

The reflash is included in the price of the kit. The Chevrolet Performance CAI kit comes with paperwork and in that paper work is a code for the dealership to reflash the computer at no cost to you.
Seems snappier now.

Welcome to the forum and congrats on the car!

Thanks for the really informative post! The GM CAI is very controversial around here. Lol

Thanks for the update. I have the Chevrolet Performance CAI on my 2019, installed it myself. Going for my re-flash this Friday, June 14. Nice to see it adds a little, it definitely looks much better.

Great looking Camaro!

From a 2019 A10 ss owner, with 3k miles on the car and completely stock, thanks for doing this. How do these numbers compare to rotofab dry? I work for chevy and can get a better price on the gm cai. ... lol

Nice post. Seems unbiased. I have the GM CAI on mine. Looks good. Other mods made so unable to confirm... Happy Motoring!

The "V" in the spacer is to eliminate a "whistle" with the CAI. Here is one of many threads that discuss the "whistle":

Nice to hear good dyno results with the GM CAI. Thanks for running the test and posting the results! I have the GM CAI and didn't see any improvement in 1/4 mile time with the drag filter vs. the blue street filter. It is interesting to see your dyno results on that too.

Do the newer CAI have vanes to direct the air through the maf? The older ones did not and I dont think they were very consistent.

I see haha.
No problem man. The flash seemed too slightly quicken the wot shifts to me.
Thank you
I’m not sure exactly but, would think they would probably be close.
Yea it looks great and keeps warranty haha
I gotcha that makes sense on the spacer. I definitely thinks it’s a nice upgrade for the car. I’m currently headed to the 1/4 mile to get some data.
I didn’t really see any veins but, there are dots you have to line up to make sure the maf is positioned correctly
