K&N Cold Air Intake (Dyno results)

Took my 2014 Jeep Grand Cherokee Overland 5.7L to the friendly and professional people at Enhanced Street Performance (ESP) in Shirley, MA. The dyno is a Mustang dyno which is load bearing so the dyno figures will be less when compared to a non-load bearing dyno like a Dynojet.

I tried my best to keep the oil and tranny temperatures the same before each run.

Made a few passes with the stk. air box with a dirty air filter (11k miles) and a brand new one. The dirty one made the most but all five runs of where pretty much in the same ballpark of 2-4 rwhp.
RWHP: 285.8@5196 rpm
RWTQ: 318.2@4209 rpm

Bolted on the K&N Cold Air kit and noticed the following. The engine noise is louder at the front of the vehicle but basically the same at the rear of the vehicle. I used both a new and used K&N air filter. The used one had approx. 300 miles on it. The best run was with the used K&N air filter. All of the runs were within 2-3 rwhp of each other.
RWHP: 296.1@5171 rpm
RWTQ: 326.2@4060 rpm

Peak gains of 10.3 RWHP and 8.0 RWTQ were recorded.



Thanks
Michael Plummer

Re: K&N Cold Air Intake (Dyno results)

Here's both stk filters side by side. Don't know why but the 11k mile air filter made the most and wasn't a restriction at this point when compared with the new air filter.



Here's both K&N air filters with the 300 mile air filter on the vehicle.



Here's the new air filter installed on the vehicle

Average RWHP & RWTQ thru the run. Pulls started and ended at approx. 2500rpms and 5690rpms

Stk Air box: 232 rwhp vs. K&N CAI: 238 rwhp

Stk Air box: 294 rwtq vs. K&N CAI: 303 rwtq

Re: K&N Cold Air Intake (Dyno results)

Well done sir.
It's nice to see some real world numbers from an unbiased owner.
I've had my doubts about intakes without tuning but looks like you have some good results.

Thank you for the kind words. Normally, I don't deal with small bolt-ons but I decided with this Jeep, I was going to experiment a little. And I'm with you, I had my doubts too and the best way for me to verify is with a dyno. Granted, my testing isn't on any level close to what the OEM may do but I tried.

Like I mentioned in the video, is it worth the $272 price tag? That's for the owner to decide but the performance gains are small but the installation can be completed by anyone in 15 minutes. Next up, a hand-held tuner from Diablosport.

Thanks again
Michael Plummer

Re: K&N Cold Air Intake (Dyno results)

I too appreciate your time(and $$$) spent testing.

I just went with a dry, drop-in AFE filter. No noticeable, proven improvements but I've always replaced paper filters with K&N or AFE since tjhe 70's(K&N).

Hi Dan,
You're welcome but like I mentioned above, the gains from my CAI testing were small and I'm sure the other CAI manufacturers will show similar results and that would be very hard to measure on any butt-dyno.

Re: K&N Cold Air Intake (Dyno results)

Nice! This is pretty cool. I have been running a drop-in K&N since the beginning (+50K miles) mostly just to have something that didn't need to be replaced all the time. I clean it every spring. I guess I perceived a more free flowing engine rev. I also think it would be interesting to see how the $50 drop-in compares to the $270 CAI. If you have the dyno time

Re: K&N Cold Air Intake (Dyno results)

Thanks for taking the time to do the dyno tests. One thing I am curious about and this is by no means to claim that your results are not accurate, but do the computers in vehicle take a little time to adjust? In other words, had he put the K&N intake system in, driven a week or two and re-did the dyno would the results be the same? or would the computer have adjusted or compensated for anything? I always thought changing something on the spot like that then immediately dynoing it might not be fully accurate. Would be interesting to see I suppose, but this guy has already done pretty much 100% more effort than anyone else has as far as research and testing of an intake system haha.

Sure no problem, as long as you provide the $50 K&N air filter.

Re: K&N Cold Air Intake (Dyno results)

Q) Thanks for taking the time to do the dyno tests.
A) You're welcome.

Q) One thing I am curious about and this is by no means to claim that your results are not accurate, but do the computers in vehicle take a little time to adjust?
A) Great question but the processor has to deal with the hand it was dealt. It has short and long term fuel trims where it can adjust in either direction (more or less fuel). We need 4 things to make an engine run: Air, fuel, spark and compression. If we add something that increases air flow, the engine has to compensate with the extra airflow by increasing fuel. It has no way of getting rid of more airflow other than thru the combustion chamber. The stk. processor has limits and when it hits a limit, it will give you a "Check Engine" light. This is when a tune is needed. Parameters will need to be changed and sometimes other parts depending on what modifications you make.

Q) In other words, had he put the K&N intake system in, driven a week or two and re-did the dyno would the results be the same? or would the computer have adjusted or compensated for anything?
A) Great question, and I did just that. I went back to the dyno on Saturday and made 300rwhp and 328rwtq. That's 4rwhp and 2rwtq gains over the last dyno session 5 days ago. We have to consider dyno error or maybe a better word be percent of error and ambient temperatures might of been cooler.

Q) I always thought changing something on the spot like that then immediately dynoing it might not be fully accurate.
A) The Mustang dyno is not 100% repeatable due to a number of variables but results should be close. You're not going to see a HP increase from a part on one day and then see a HP decrease a week later. If anything, your HP increase may be slightly more or slightly less depending on certain variables. This is providing you don't have engine knock or some other variable that may reduce total timing.

A good example of a bolt-on part that will not work, is if you hand a hand-held tuner and you uploaded a 93 octane tune and you saw no HP gains. It could be related to the (2) knock sensors the HEMI engines have. If the knock sensors detect knock it will retard total timing depending on how bad the knock/detonation is. And your dyno results will show little or no HP gain.

Thanks
Michael Plummer
