Been watching this for awhile, seems they just finished it up for the 09-11's. Kind of expensive, but i would like to pick one up eventually. What do you guys think?

When are people going to understand that CAI does not increase HP. I like where is says 25-50 HP gain but with a computer tune. Your motor is only going to pull so much air in. The only thing a CAI does is give you more noise under hard throttle and makes you think you have more HP but you dont. Your truck already has a CAI but have sound deading baffles to cut the noise down thats it and it does not restrict air flow. DONT BELIEVE EVERYTHING YOU READ AS THEY ARE TRYING TO SELL A PRODUCT.

 

Now if you have a motor that pumps out 600 HP then yes you need more air flow in but that is at high rpm

At least they were honest about needing a tune for full potential. Before I got my tune I dynoed my truck with a new cai and gained about 6hp from stock, not sure how much I gained from the bb tune with the cai but did get a nice jump in hp and tq.

OK, so let me ask here. I am not new to GM vehicles, but I keep reading where you guys say there is no gains to be had. Do you have conclusive proof of this?

 

I have a 2009 G8 GXP. Car came with the Vette LS3 rated at 415h/415t from the factory. On back to back dyno runs with a Rotofab intake kit I picked up 13rwhp before we even touched the tune on the vehicle. I went from 342rwhp when I came into the shop and left with almost 363rwhp after the tune was done on a 500 mile old vehicle. Since then once the motor broke in the car is now a little over 370rwhp.

 

That is fact, not fiction and not word of mouth from the maker of the CAI kit. The stock intake tract is designed for NVH (noise, vibration and harshness) in mind. They use baffles to to make the truck quite under load, not exactly the best thing when it comes to power. A engine is an air pump, more air into the motor and provided you can get the air out will make more power.

 

If CAI did not work I would suspect GM wouldnt be offering them as a after factory part you can get thru the dealer then now would they?

Yes they would, as they are in the market to take money from those who believe the hype just as anyone else is.

Once again hype that is not true. We have done back to back runs and each time we have always seen a gain with a good name brand CAI kit. Each and every time, gains that were still there months down the road. The easier and more efficeintly the engine can pull the air in the more power that can be made, there is also an effect called sonic super charging that happens when air is pulled into the engine and then hits the backside of the valve as it close, that airflow is reverberated and then pushed into the next open cylinder.

 

So once again, CAI will produce gains and you dont always need a tune, but you will make more power with a tune if you are ok with tuning the vehicle. I may even tune the 2001 Silverado here once I get some time.

There was also a noticable difference in my truck after my Airaid CAI install. I had my truck on the dyno at my race car engine builders after my CAI install, it showed a gain of 9hp (don't remember the torque but that also went up, would have to find the sheet) Going to have to have it done again after tune and exchaust.

Some people will swear until they are blue in the face that a CAI is usless. Doesn't matter if they are presented with evidence or not.

I can tell anyone who will listen to reason, that CAI kits DO make a difference. Even more of a difference when combined with a tune and exhaust. I have tested my Camaro on the Dyno and verified this and have seen similar results on many other vehicles. The CAI is not only about the volume of air, but how much easier it is to pull air into the engine without all those silly noise reduction baffles that GM is required to install.

 

My experience is with K&N kits and now with the Volant system. I am not selling anything and not trying to argue.....I just honestly believe they work.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By newdude · Posted

      Engine failure requires radiator replacement per GM if it contains an engine oil cooler.  They do NOT want them flushed.  Radiator replacement is also required for the 6.2 recall if the engine fails.   Here is the TSB the dealer is referring to - 22-NA-074 1..2    Its a slightly older version, but the current version of it covers all model years 2000-2026.  So if enough failure debris was present, it gets an oil cooler.  If that is part of the radiator, it gets a radiator.  Also, same for oil cooler lines.  Those get replaced.     Now something like a 2.7 Turbo which uses an oil to water heat exchanger for the oil cooler, the radiator would be left alone but the oil cooler would be replaced, as well as any lines.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Doing the right thing, replacing both valves is the way to go. The valves with the ball leak far more often than the schrader. Never cared for them. The accumulator really should be replaced if the system has had no pressure in it and it was a keeper, but since you're looking to sell it, bet you can get by. Did you pull the orifice screen and see what was there?   Shame you can't get 134a. Hopefully the previous repairs included dye.   Some of the R4s I messed with developed leaks where the line sets connected or the front seal. Had one where the HPCO was leaking. Front seal would only leak under pressure. See any obvious oily spots?   I've got nitrogen I use to test pressure and to help dry the system prior to evacuation.   Keep up the good work

      Next time you're on a road trip to a state where you can still buy it stock up on 12oz cans, you might look into getting certified so you can buy it where you are as well. When they switched from R12 to R134a the test for certification was easy, they basically just wanted the $25

      Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!
