HKS RS vs. Stock Airbox & More <My Observations>

A stock 2004 Dynoed 251!!
A stock 2003 dynoed 218!!
I dynoed 308. A 2003 with UTEC, cams, etc, dynoed 319. A 2003 with a Power FC and boltons, and cams, etc dynoed 320.
My point is, the 2004 picked up a considerable amount of power with an intake.
I am think that an aftermarket intake on a stock ECU may cause the MAF to read erratically. I am not convinced that this means you will lose power.
EVERY SINGLE MEMBER of the North Texas Evolution Owners Club ALL picked up power with an intake. Over and over again it was proven.
You guys are CRAZY in this thread!!!!

I always thought and every one know that mustang dynos read %15 lower than dynojets (fact).. They read a bit higher than moon dynos... How come a stock EVO ran 251 and 218 on a mustang dyno??? a stock EVO should run no more than 210 at its best at mustang dyno.. The funny thing is what you said above which I found extra extra weird How come an EVO with an intake will dyno at 280's ???? I mean common do you have dyno sheets to post here or you just coming out with these numbers from your A$$??? Every tuner here on EVOm including Shiv, AL and TT will agree with me that a stock EVO with only an intake WILL NOT PUT DOWN 280's (no way) especially on a mustang dyno... I don’t know how your forums run but we are not born yesterday here

It assumes a reversible non-entropy generating system (impossible) and uses constant specific heats (ideal gas assumptions) which air or any other gas really isn't. It's good for ballparking. That aside and back to the coversation on how the HKS RS impacts the A/F ratio can anyone speak to the nature of the MAF design? I honestly don't know enough about the Mitsubishi model to make an educated guess on the effects of flow characteristics on sensor output.
Let's all get on the same page.
1.) Does anyone know if the Mitsubishi MAF sensor is in fact a Von Karman Votex style sensor.
2.) Does anyone have experience with this style of sensor and can explain if flow characteristics can decrease it's effectiveness.
3.) Is the MAF sensor as critical as the intake charge temperature sensor?

What is the purpose and/or reason the hood is up when dynoing a car? Wouldn't it be more beneficial to dyno the car with the hood down to produce a more accurate "on the road" environment?
You certainly don't drive down the road with your hood up...

you cant close the hood because there are wires connected to your engine

I see them connecting wires right where the valve cover is... they even remove my mitsubishi black thing fom the valve cover

yup exactly now I remember cuz I asked him and he said it was for RPM

Ok back to your regularly scheduled thread!
Chris
dam
best of luck. I believe that you will make over 600WHP but I dont know about the 700WHP
now take your time and test everything before you fire it up... if it works you are the one who will be building my new engine

Hey dipsht, I am saying that the 04's are putting out considerably more power than the 03's since you can't seem to infer ANYTHING on your own. The dynos will be posted all in their own thread soon enough. Then you can believe it. Also, since you are such a fckn expert, I am surprised you missed the fact that 8 HP can easily be changed since the Mustang is a loaded dyno. If the dyno is run with a higher level of HP needed to maintain 50 MPH, the number will read lower. For consistency, the Evos at Wasabi are run with 13.2 HP/50 MPH. FIS uses 11.5 which will read about 5 HP higher. Also, there are a lot of different Mustang dynos and one in Cali or NY will not read the same as each other or one in TX due to temp and altitude variances. Fortunately, when I post all the dyno charts, they were all from the same day and same dyno. That's as good as you can get.
And for all your personal ricer tuning expertise is about to go out the window when you see the charts. Just wait.
