Dyno & testing of P2R Intake Pleniums

Dyno & testing of P2R Intake Pleniums
I'll make this new post & then merge it into the other thread in a few days...
03 CLS 6MT, mods in signature.
Ok on my car these don't do much. See dyno graph.
Before
HP 252.85 TQ 218.33
After
HP 252.79 TQ 219.39
Maybe it's the FL weather, Maybe it's the dynojet, I don't know. My butt dyno thought there was something but after the ECU adjusted it feels the same as it did before the install.
I did do an after dyno at Power Rev Racing's shop the day I installed these & that yielded 265/229 but I don't have a before on that dyno to compare.
Everything is working on my car & I'm running 235-45-17 tires on stock rims. The other cars I've seen dyno'd are 225-45-17's or stock size.
I'm thrilled my car is consistent in the 250WHP range though. That's a great number for just bolt on's.

Did you uninstall them and then reinstall them for this dyno? (I know that seems like a dumb question, but I'm still stumped). We have a pretty much similar set up, except for exhaust, mugen cooling mods and of course that your a 6-speed.

The fact that my car ran such high numbers on P2R's dyno is a concern. I'm not sure why it ran a 265/229. His dyno is a different brand dyno.

After you did the initial dyno, did you reset the ECU and drive around for 30 or so minutes? the ecu needs to adjust AFR to compensate for more air... when I installed my P2R TB Spacer and dyno'ed without resetting the ecu I made the same power but I was running leaner due to extra volume... there was quite a bit of power to be made if the mixture was richened up from that point.

If left untouched the ECU will eventually adjust to the extra air volume and compensate with more fuel but if he just installed the plenums and did a dyno run he wont see any gain at all, even a loss in power wouldnt be surprising.

The before & after dyno's were a week apart. ECU had plenty of time to adjust. I drove a few hundred miles.
Last I checked there's nothing made for tunning for a 6 speed. Nothing that doesn't require work to make it work.
I'm not into messing with wires or extra sensors.
I'm running 93 gas & am not too lean, The car runs great. The power is all streetable. I'm happy with this.

i would think you would see about 10whp/10tq with the afc neo, which is very affordable and with a boomslang harness is entirely plug and play.
in regards to these plenums... it appears the only way to get gains is from a tune. IMO this are only as about useful as your throttle body inlet size.

whats the biggest TB one can put on ou cars, maybe i shud just try a bigger TB + the already installed CAI & Headers
![Too Cool](https://acurazine.com/forums/images/smilies/toocool.gif)
What do u guys think.
I believe the bigger TB still keeps the same outside diameter. so that all other mods like the p2r /gaskets or spacers would still FIT.
wht do u guys think ?

Why dont you come to my shop when you have the chance. We will uninstall the plenums. Dyno the car. We will then reinstall them and dyno the car again. This way the conditions can be the exact same.
I think the main reason your not seeing a gain from the plenums is because the ecu is adding fuel and pulling timing because of the added air fuel. When you add a mod to these cars. Most of you say you have to wait until the ECU adjust. But what you will notice is if you install a bolt on, and dyno right away. You will see a bigger HP gain. The reason being is becuase the ecu didnt adjust yet to the extra flow, and the car will run alittle bit leaner resulting in a HP gain.
What happens is that when you dont have anything to tune the car. The ecu eventually learns the added flow and matches back up the fuel and timing to make it back to what it thinks is stock. When you have something like a VAFC, or some other type of Piggy back system. It actually overrides the stock ecu to keep the air fuel where you set it to be.
For example, if you turbo a CL on a stock ecu. Without anything to tune. It will start running worst and worst every day. But if you have a Emanage or something. It will always run how you set it up to run.
So in this case. If you come back to my shop and we do both b4 and after. you will see a gain, but you will in all honesty want to get some kind of something to tune the car. You will not only be able to make more HP, but also be able to always have that power there. This rule does not only occur with the plenums, but will be the same with headers, intake etc. you will actually see a bigger gain right after install, because stock headers are so restricted, that even after ecu compensates from aftermarket header, that you will still have some gains, but not as much as right after install.
Older ecus didnt use to do this. On a newer car like a 2006 Civic Si for example. Alot of people install intakes on the cars, and they go and dyno a week later, and find out that they have the same HP as they did before the install. But thats only becasue they dont have any kind of management that will not let the ecu go back to stock.

But if you have the time, since you are local, i would really like you to come by so we can do this b4 & after dyno. I dont want to have any disappointed customers from something that I know works for sure.
Also just a quick note. On a butt dyno, when you can feel something, normally means gains are there. Reason being is becuase when you do a specific mod to a car. Like exhaust for example. It sometimes makes mid range gains, so where you can be 60% throttle and can feel more HP. Sometimes gains are more in the daily driving situations rather than full throttle situations. So mid ranges gains can be there, but not Peak numbers. Not saying this is the case. just a side note.

I'll keep that in mind after the holidays are over.
I stated from the beginning these are on MY car. Someone else's car may have different results.
Another dyno test would be conclusive I guess. Just need to find the time.
On a side note, they do look good actually. I've gotten used to the under hood look. The guys at the dyno shop were raving about the quality & how they look good.

Just right down the tune in the space provided for you in their owners manual and you should be good, I just never thought about doing it before this.
Emanage is more advance with cool ignition features and 16x16 maps. AEM FIC has 21x7 maps but not as many gizmos as the GEU, however Greddy as you might have noticed from all the threads and differnt boards has horrible customer service, they can't even seem to help themselves let alone us.
But yeah you can just change the settings back and roll, or like me roll with the rich settings. The low throttle setting s dont really seem too affected 0 and -1 values, although I don't remember what those values were and how lean they might have been. The Greddy Emanage has been known to "unclamp" the MAP voltage SIRSIG is a example of this, the MAP voltage was off and the car was pulling timing like crazy.
