CAI Comparison at LMR Dyno day

You are reading that correct... and Hennessey got the first runs... LMR was a hot run.

From the videos it doesn't quite sound like they got on the throttle the same way with both runs. For the 10 or so dyno runs that I was there for yesterday (I must have left rght before yours because I remember seeing that blue Viper run), it seemed that the first pull was a warm up pull and they really got on it during the second pull. I know they certainly did for my run and there was a 4.5hp difference between the two runs with no other changes.

Hopefully these numbers would hold true on another dyno somewhere else. If so, that's awesome and I wish LMR would make a CAI for the v6 too.

I saw your car but didn't know who you were there. Wish we could have met up.

True the first video is also the first dyno run. Notice the guy says 322 at the end. But the he Dyno Sheet shows the second run which was the best Hennessey run at 325.

The second video is the 3rd Dyno run at 333 with the LMR CAI.

Ahh the skeptics. Don't worry, there were 50 or so of us watching this happen yesterday and everyone was a skeptic, including the LMR crew. Josh even commented right before doing the dyno on the LMR to the crowd that "This could turn out very good, or it could turn out very bad for LMR."

There was no funny business, it was done in front of everyone and pulls were done back to back. The two dynos shown above were the best two pulls from each airbox.

Good to meet you yesterday Mike!

Makes sense to me that hennesy makes less power for a few reasons:

Their heat sheild does not seal off very well when compared to the LMR.

Their intake tubing is 2 pieces, so there is one more joint for air to run over and create turbulence, and turbulence is not something you want in your air flow

Just my .02

I have been very impressed with my LMR CAI...but it is still just a CAI.

The guys at LMR is what makes me impressed the most. TOP NOTCH crew there...

[Crowley]

Again, not doubting the results, but I would like to see A/F with the different intakes. It is possible that the difference in gains were A/F related.

Thanks,
Crowley

By the way, just so I am clear about my perspective, I have the Hennessey intake kit on my SS and I love the sound, performance and look. I am also running about 575 rw hp with their blower kit and a few other tweaks. I just think a plastic cold air kit looks cheap like stock. So I will say that I am biased.

LoL, Sorry my friend, but nothing fishy going on. We did this TEST in front of over a couple hundred people. We had a huge dyno day/car show and while straping down one 2010 Camaro I noticed the Hennessey CAI system. I asked the customer if he would mind us installing our CAI system after we did a baseline on his to see the results. Trust me, it could have made us look like idiots if the results dropped but knowing our product I knew it would out perform theirs. That is why I took the risk of doing it in front of so many people. Keep in mind that we dynoed the Hennessey CAI system first so the motor was already heat soaked for our CAI runs and it STILL picked up 8 rwhp and 14ft lbs of torque over the old system that was on his car. Like I have posted in other threads, I am more than willing to put our CAI system up against any other system on the market today. If anyone has any questions please feel free to give me a call at the shop.

Wow, I am very impressed.

I guess that plastics and heat shield really make the difference.

LMR is very rapidly moving to the top of my list for a CAI...
Thanks for the info

[thecamaroguy]

Red Hot...

It's a great product. But in the end, it's a CAI...

The guys at LMR make it even better. They stand behind you no matter what!!

[Bbrock25]

This has just sold me to LMR. Only thing left to see is when Vararam gets there CAI out on the market to see there #'s. But probably going with LMR anyway.

The pulls were made with an open hood. Not much of a "seal" taking place when the top is popped

Quite a gap in results for essentially the same thing (free-flowing tube with a K&N filter in the same location).

But then again, the test was a bit flimsy on the scientific end of things.

Ideally, you would've done the Hennessey pulls, then let the car sit for a few hours before doing the LMR pull (as Mike's stated, his car had been sitting for 3 hours). This would help to balance the comparison for a more accurate test. Granted, time come into play as people were waiting to see the results.

The engineer in me wouldn't hand LMR the win with those numbers.

From experience, my own car runs better after its been driven and put through the paces vs. starting it up after its been sitting. Operating temperature and an evenly-distributed temp al a coolant flow is better than strapping it down and giving it hell after it has sat with the same hot coolant in the Texas heat for hours on end.

My bet is the HP/TQ difference is marginal under similar conditions for these two CAI's.

In the end, I'd go with the one that fits your tastes. Debating heavily over CAI's is only an issue for those who plan to keep it basic with bolt-ons (and when you're only doing that, why NOT go with what looks best to you?). Once you start digging in and doing real mods and getting actual tuning done, which CAI you have is more of an afterthought than anything.

People don't hear my car and ask what CAI I'm running

Now to follow up with some 1/4 mile a/b comparisons.... that's what I'd like to see.

Yep... I have the B numbers... will be a month or so until I can get the A numbers... going to be out of pocket for a couple weeks starting today...

But that's a lot more subjective than Dyno...
