Helix intake rocks ! A great HSK knock off at a much better price and with a much better filter

Mods are :

Helix Intake
3" Exhuast - STOCK CAT !
Hallman MBC
Walbro pump

Note* stock bov leaking slightly - forge recomended

 

Flashed of course right? And that 3" exhaust is 3" DP, stock cat, and 3" catback (What brand), and what kind of evo is it on year and model? Reason I ask is I have seen you have greater success on the evo MR. Also you got a dyno plot with same mods with another intake?

 

2003 evo

with stock cat this is about the max on pump gas

 

Flashed though right? And it looks like the injen intake puts out more power if it this plot is also flashed. Which with hp that high it looks like it.

 

Thanks Al the car feels real good.
Car has 3" helix dp and 3" Rnr V2 catback with magna flow muffler.
It put 270 hp before the flash

 

Al, the AFR on this car during spool up looks as flat as the rest of the AFR curve in the mid to higher RPMs (my message continues below)

By contrast, on your recent Stage 4 graph, the AFR is much leaner during spool-up, which seems to make more sense to me since the car isn't under full boost during spool up:



Can you explain?

Thanks.

 

Only issue here is that one dyno operatoir sparted the sample earlier than another - you will notice that the sheet on the bottom starts thge sample much sooner than yours at 3100 vs yours which is well after 3600

Also the other car is tuned differently and has different mods - cams and no stock cat

 

Hey al you said he has

Helix Intake
3" Exhuast - STOCK CAT !
Hallman MBC
Walbro pump

Ok i have the same setup on same year car pluss a testpipe and your flash.

If i add the walbro pump and the helix intake, will i need a reflash? I hear intakes can do tricky things to maf, this is why im asking. thanks man

 

Yes - you will need a retune for sure

 

Good stuff! I just got my Helix intake on, good stuff! I cant wait for a tune!

 

Will the car be drivable untill i get it retuned? Or will i have problems. I have to schdule the retune around work, as my car is the ride. thanks man

 

Not a good idea to switch intakes without a retune - you can drive if you stay 100% off boost

 

Ahh ****ty, well you da man. Ill get the parts on the way then holdum till i can get the ecu back out to ya. Ill have to pick up a banor in black if you have any. gotta rep

 

i had my car tuned with a safc II for an hks intake. if i swap it out for the helix would you recommend retuning? (i swapped the hks for stock airbox, but looking for a new intake)

 

Acutally 05s in general (not just the MR) have been seeing better results, mostly in part because of the 10.5 turbine housing! Glad I have an 05 already!
