Does anyone know where to find 2" NACA ducts? If running large radial mount calipers there's plenty of room for 3" but otherwise you're stuck on 2" nozzles on factory brownbos.

see you at the track!

 

The last time i played with NACA ducts/brake cooling was on my 1.8t A4 (see lower bumper) with stock calipers. I even tried fans directly on the dust shields before i got Stoptech brakes


I was not expecting to have similar issues with the evo, though I think this time my autox brake pads are just too aggressive for TT.

 

I always forget that ebay exists and could never find the 2" NACAs on Pegasus, Summit, etc. I've had ducting solved for a while by relocating the oil cooler and adding blockoff plates with duct inlets onto the bumper. To trap more air and be more aerodynamic I think a set of bumper shutters with a simple opening would help them out but they've worked fine for me as is.

 

I feel like there's missed opportunity here to maximize the surface area that would funnel in the air. how about these

thinking about swapping out my omni 4bar for stock - is stock map sensor suitable for a stock turbo car on e85, making ~360whp? or should i stick with the omni 4bar?

 

Evo X / JDM Map sensor is good to 31-32psi.

 

sorry this is for an 8/9. or is that what people are using the evo 9's?

 

Yes. Before the 10, we would use the JDM 3 bar map sensor. Now with the 10 out, it's the 10 / JDM 3 bar map sensor. Same sensor.

 

perfect - yea would definitely prefer the oem reliability from a mitsu map sensor.

 

Just remember you will need to make changes to your rom for it to work correctly. It's easy though.

 

right, thinking about it in conjunction with a retune.

was about to buy from a vendor but ebay's got these suuuuper cheap if anyone else is looking: https://www.ebay.com/itm/13363942564...wAAOSwT-he~pge

not to mention all the take-offs from stores that part out cars

 

I don't know if I'd trust unbranded eBay parts shipped from China over the Omni 4bar.

I'd try to get an Evo X take-off if possible. That's what I have. OEM is best.

 

true good point - plenty of take offs on ebay too

 

There are vendors that are on ebay selling replica sensors now. Extremely good replicas. IACV, MAP, and other sensors. Dont buy them as they are not the same quality as OEM. You can identify these replicas as they will be priced lower than normal.
