Default Grimmspeed FMIC group buy - I'm 35/100

I wonder if anyone from the GS FMIC group buy is here. I have a few friends and followers who have asked me about this FMIC specs. Someone came up and thought the core is only 2.5" thick. To clear that up, I will drop some info for those who curious.

These info below might be different than official GS release on July. Very unlikely but if it does, please don't @ me.





Core:
  • 27x11x4" Cross Flow Core – Durable Bar and Plate Construction, balanced perfectly between pressure drop and heat rejection
  • Cast Aluminum End Tanks – Designed for equal flow distribution and minimum pressure drop
  • Steel Bolt-on Mounting Brackets – Robust mounting solution to minimize movement and maximize adjustability
  • Virtually No Permanent Vehicle Modification – only two tiny ribs need to be removed from the OEM undertray
  • Compatible With factory or GrimmSpeed Intake – [Removal of snorkel required; GrimmSpeed Intake recommended for maximum performance]
  • Pressure Tested – Cleaned, sealed and guaranteed to work prior to delivery
  • Available in Raw Aluminum or Satin Black Powdercoat [*Raw option only available post group-buy] – Uncoated or resilient powdercoat finish to protect against rock chips
  • High Quality, Pre-applied GrimmSpeed Vinyl Decal – Show your pride for the BEST front mount intercooler on the market, or easily peel it off.
  • No tune required – No change in maximum boost or time to spool
  • Welded and Inspected by Hand in Minneapolis, MN - For consistency and top quality control

Piping
  • Thick .090” Wall, 2.5” Diameter 6061 Aluminum Piping – Beadrolled and CNC mandrel bent on a large radius for max flow; lightweight and heat dispersant
  • Precision Pipe Routing - Retain factory components and avoid unnecessary trimming
  • Retains Factory Fog Light Mounting
  • 5-ply Silicone Couplers – Custom molded and reinforced to last through demanding environments
  • Breeze Hi-Torque Liner Clamps – Stainless steel for lasting looks and grip with integrated liner to prevent damage to silicone
  • Durable Red [During Official Release] or Black Wrinkle Powdercoat – Keeps pipes protected against corrosion while looking great and a perfect match to your other GrimmSpeed parts.
  • OEM Bypass Valve Location – Eases installation and allows for use of most aftermarket BPVs

Can't wait to install this.

Seems like a good kit, but maybe too little too late compared to ETS, PRL, and Perrin. I'll be keeping my GS TMIC for quicker response on the track though.

I was hoping for something a bit more revolutionary for them coming to the market years after anyone else. Although I am not sure what you can do "better" on an FMIC vs one of the aforementioned kits.

I hope they post some analysis and stuff on their site like they have in the past.

GS actually posted graphs of test runs on the closed FB group. Let me know if you want to see it here. I made an excel spreadsheet to compare it to all of other big names FMIC and surprisingly GS stands out the most for my needs as in feature/value per dollar. I just don't see any number yet.

Maybe I misunderstand the TMIC vs FMIC debate on the FA platform. Wouldn't a FMIC provide better (quicker) response since the turbo is bottom-mounted on the FA20? Less time traveling through charge pipe and into a TMIC and all that.

Nothing but good experience from my GS TMIC btw, just curious considering the EJ platform has the turbo closer to the TMIC thus resulting in better response than a FMIC -- We see the opposite on the FA platform.

There's still quite a bit more piping on a FMIC kit than a TMIC for the FA. Probably not as much as on an EJ, but still more than a TMIC.

No tune required – No change in maximum boost or time to spool.


How? There is quite a bit of length added to the charge pipes here.

I'd guess it's negligible if the claim is legitimate

obviously in reality any increase in delivery volume will require some amount of time to boost

Not sure about newer WRXs but other DI platforms (mazda, vw, etc.) aren't so nitpicky about needing to retune every time you pop the hood. The ecus have more flexibility and processing speed/power, so more actively make tweaks based how the engine is behaving IRL.

As far as I know this should be the price, but I'm not GS so these prices can change when the official product released.

Because they are speed density tuned from factory, the FA20DIT is still MAF based and requires a re-tune for most mods.

The mazdaspeeds are MAF based. You can do tons of mods without needing a retune, FYI.

I don't know enough about the FA, was just a thought...

I agree ^^^

This came down to the turbo's location on EJ where it sits next to TMIC and on FA where it sits very low in front of the engine, just right on top of the belly pan.

On EJ, TMIC -> FMIC will add an additional cold pipe and a hot pipe to air path before it can reach the throttle body. I believe the turbo relocation kit on EJ exists purposely to remedy this issue.

On FA, TMIC -> FMIC will add an additional cold pipe but also eliminate the OEM charged pipe because the new intercooler now sits closer to the turbo.

Pls forgive my ignorance but are all EJ speed density? I heard SD is the way to go on FA but it's relatively new on my platform and has been giving issue to tuners so most people are still MAF.

EJ's can be tuned for speed density with an additional IAT sensor, then it has to be mapped with custom tuning (COBB etc.).

FA20 does not need an additional sensor and COBB has just started rolling out this capability via Accessport. If you have a custom map previously you are more than likely tuned on MAF unless you told you tuner you wanted speed density recently.

other than trying to get more power with some more timing a more efficient intercooler absolutely would never require a tune

Since this is being discussed here this is a good discussion from a good tuner.
