Default Best air filter location on turbo setup

Hello,

Got a GT25 turbo on my Mk1, it's got a front mount intercooler but I'm thinking the cooler the air goes in the cooler it's going to be when it passes through the intercooler etc.

I'm guessing I can take a hose from the turbo inlet to the front somewhere?

You know what this forum needs? A filter that won't unlock the "post new thread" button until you've made a set number of searches.

And this is precisely why I don't use Forums anymore. Grow up!

Because you're too stupid to use them properly?

Welcome to MiataTurbo, you have activated the standard new-user hazing ritual.



The absolute best location for the intake air supply would be a hole cut into the top of the hood with a pipe run up through it to forward-facing scoop similar to what you sometimes see sticking out of the hoods of 60s-era musclecars. (Yes, those knuckle-dragging ironheads actually did get something right.) The hole should be well-sealed such that hot air cannot easily rise up from the engine bay into it. This provides both the shortest possible path on the vacuum-side of the compressor as well as nearly complete isolation from heat produced by the engine.

Obviously, the acceptability of this solution is modified by both aesthetic concerns (do you want to cut a hole in your hood?) and practical concerns (is your neighbor an ******* who will stuff rubber ****** and handfuls of cat feces into your intake scoop at night?)

This is a forum, not AnswerToby'sQuestions.com. At least try to do some research before you start creating threads.

The great thing about shouting down at people who ask questions and telling them to search the forum is that when people in the future go to search the forum, they'll get nothing but threads of people getting angry at people asking questions and telling them to search the forum.

It's like an ouroboros of making the search functionality completely useless.

Hmm maybe a 'useless' button. If a thread is useless and gets ~20 'useless' votes, after it's dormant for 1 year it is deleted.

But sometimes someone sticks nuggets of awesome into useless threads. Maybe posts with a negative enough rating shouldn't show up in site search? It'd still show in Google search, which is what I generally use to search this site anyway.

By the logic above, Peter Pan and the Holy Grail would have long since been nuked, along with Fae's build threads, and damn near everything ever posted by Hustler up until the point he became a moderator and his ********* re-receded.

How many posts on the site have -20 props? Besides the one where Rick announced he was selling the site. And if 20 isn't high enough, raise the threshold higher. Or maybe with 20 'useless' votes it gets marked for review in 1 year by a mod, who can then decide to delete it or not.

I do like the idea of them not showing up in search, though I'd hope that would include the 'useless' threads getting a robots.txt so they don't show up on google either.

I'd imagine the best location for an air filter would be somewhere before the turbo. Anywhere else in the system just seems a bit useless.

Individual Throttle Boddies are ricey and hard to tune. You can get the same performance benefits from Individual Air Filters (IAFs):

Oh I get it. So what we have is a closed loop system. You filter the air at the intake runners and that filters out the exhaust fumes coming from the turbo. Duh.
