PSA: Get an Eventuri Scoop

[karter16]

It would be great to hear some modern thoughts/opinions on this backed up by data if there is any, I relocated 5ish years ago.

I thought I saw a post where Bry5on had done logging on this but now I can't find it.

Just drill a hole into the air tube.

Which air tube? Unless I'm missing something it seems like in this setup I would have to drill into the Karb box's carbon snorkel, or the top part of the scoop's ducting? At present my IAT is drilled in to the short rubber/plastic duct piece that goes from the top of the brake duct (slash passage next to the fog light) and would feed up to the stock air filter housing if it hadn't been deleted for the snorkel. Does that duct still remain with the scoop installed?

My take on this is that relocating the IAT isn't really a benefit at all. IMHO You want the IAT in the stock position to get an actual reading of the temperature of air entering the throttle bodies. Appreciate that when the car is sitting still you get some heat soak, but all that does is an increased safety factor while the car is at rest, as soon as you get moving the flow of air over the sensor returns to an accurate reading. If you have the IAT elsewhere you are creating a condition where the intake temperature the DME is getting is artificially low and the DME is then making decisions off of incorrect information.

I've heard so many conflicting opinions on this and both make sense. It's plausible that relocating causes the DME to be reading temps that are too low compared to what's actually getting to the throttles, but it's also plausible that heat sink isn't the issue that people are making it out to be. But I'd been given the impression that the stock location is prone to considerable heat sink and reading higher more than just at rest?

do you have the scoop hooked onto the snorkel?

I don’t. But the Evolve box turns down and the mouth faces exactly where the scoop feed hole is. Probably helps that my IAT is at the end of the downturn and basking in the fresh, cool air.

Either way, this silly $200 part was transformative for my car.

I used to run an Eventuri scoop with the cf airbox as well when I still had stock air ducting and I concur with the above. It's a great way to get cooler air into your motor, which means more power.

Now if you run brake ducts with hoses like me, it's even easier. Just by a Y-Splitter for ~$20 and feed one hose directly into the air box. Actually, from a cost perspective it is not more expensive to buy proper brake ducting and a Y-Splitter vs the Eventuri scoop. Just means you have no more fog lights...

+1 to running a Y-splitter on 3" brake ducting to intake feed

I have a brand new Eventuri scoop sitting on the shelf, I'll have to test it out sometime.

Edit: ignore - I misunderstood the post.

I've always wondered about this. Like many I have a CSL airbox and have relocated my IAT to the brake duct hose that this scoop replaces. If I replace that duct with the CF eventuri scoop, then there's nowhere sensible to relocate the IAT too, and should put it back to the stock position.

Question is: does the benefit of the scoop outweigh the benefit of relocating the IAT?

Hey guys:

Quick note and friendly PSA on something that shouldn’t have made a noticeable difference but has seriously changed my car for the better.

Background: I have an Evolve airbox and everything had been working fine pre-scoop. Then, a sale popped last year on the scoop and I figured it was an cheap way to test logic (and potentially science).

I am happy to report that, once installed, everything worked—and, more importantly, sounded—much better. I am now convinced that my Evolve box was starved for fresh air. Even with the elephant d*ck downward turn at the inlet.

Throttle response, urgency of revs and airbox growl are all greatly improved. Simply put, it’s a great $200 mod.

Note: I didn’t want to call attention to it so I plastidipped the scoop black. Out of sight but not out of mind.
