When I installed the RMR intake a while ago (over a year now), they told me it should yield about a 6-8 hp gain. Looks like they were right (again). Of course the thing to keep in mind is that for the most part, every mod benefits each subsequent mod. For example, by improving your intake, when you improve the exhaust, airflow overall is improved. That's why I followed the path of improving all airflow (IC pipes, intake & pipe, 3" exhaust) as my first step in modding the Evo. Now I am working on fuel and boost. The last stage will be internals and beefing up the driveline.

Al, you are right. The HKS RS kit hits a lot harder compared to the rest, and switching from a panel filter to teh RS kit makes us add a lot of extra fuel on topend. I have compared several AEM maps, and the ones with RS kits are the "fattest".

THE APS intake is seriously powerful - but requires a full custom tune b/c of the way it significantly effects the air flow signal

Im just playing devil's advocate here, but isn't it true that the difference in power could also be attributed to several other factors:
1) varying conditions when the car was dynoed
a) the ambient temp
b) HOW it was dynoed, e.g. whether fans where placed in front of the IC's and the intake
2) the amount of time after the respective intakes were put on, to allow the ECU to adjust to them

We did these SAE corrected and uncorrected - the temps were basically the same
Furthermore - we see these kind of numbers on all the cars we tune with the intakes and ones without - they all fall within a certain range and we see the range a significantly higher level on cars with the buschur inatake and the RS suction kit
Finally - keep in mind we don't sell HKS and actually I do not reallly like the guys at HKS USA so there is no financial motivation at play here
I am simply trying to keep all my customers up to date on what works the best as obviously when we are custom tuning the cars we want to see big whp numbers on the dyno sheets
LAST thought - WITH the DYNO FLASH - you need to change your tune when you change intakes

WHY - I can't tell you but I am seeing a trend in DOZENS of the cars with AEM intakes

didnt dave have the AEM and a 2 1/2in dp, and muffler delete, boost controler and fuel pump dyno 303 whp and 324 lbs of torque. if he had a full 3 in i bet he would have made even more. i mean you flashed it the agile meet nice curve btw

Yeah I figured because your tuning for THAT intake at THAT time and your leaning it out to a safe level. Any change to the intake...and you run the risk of going too lean and blowing stuff up. Just wanted to get your input so the others know for sure...someone was bound to ask that didn't know for sure!!!
STILL loving your tune Al....just blew a newer style M3 on the way home today. Was a short burst...I don't like street racing....maybe 1/8 mile or slightly more. When I backed down...he flies by full throttle and honks his horn and flips me off. LOL my bad...I don't like people riding my @$$! LOL

.That Dave would be me ;-) Nice to hear from ya again!! Yes, I do have the AEM and have no problems with it at all. With my mods listed below I did make 303hp/324tq at Agile
Yes, I do need to get a full 3" turboback instead of the 2.5"DP and Muff delete but I need some of that money stuff
BTW, I think I got some good results out of the 2.5"DP and Delete pipe...

we still need to hook up and go bust some SRT-4 ***** some weekend.

When anyone sets a car up on a dyno you have to open the hood and let the fan blow in cool air right? But under real everyday drving situations the bonnet is closed and the filters are sucking hot air from inside the engine bay and there will significantly less air blowing directly into the filter because there will be alot of turbulance within the engine compartment when a car is moving... doesnt this decrease power?
Just a thought though....

Thanks Al for some dyno data. It looks like the HKS RS PERFORMS real well especially with ECU tuning...but WAIT...doesn't it filter for "crap" and not worth the money spent?
