That JayDEE-EM tyte carbon fiber comperssor shield probably set that dude back about $600 Dollhairs... Thats redonkulous... Cool setup overall though

This is so y8s approved I considered making a graphic stamp that said "y8s seal of approval" but am too lazy, so just imagine one.

Seriously, this is always how I envisioned my dream turbo build. big fat plenum and gold foil included.

Please for the sake of my dreams include the right type of minimal flow restriction intake on the low pressure side of the turbo. It involves a filter box and a very nice trumpet leading into it.

like this idea:



but maybe not so gaudy. Like a stock NB2 air box. they're basically done right--even with the funnel opening behind a wall near a hole in the fender.

That's a sick setup, but I'll bet he doesn't have ITBs.

Oh, and Renn; they're TWMs. A better pic of the throttle linkage:

I'd probably try to use the airbox I made the other day, and am about to remake with a few improvements, so documented in my Sweet Box thread.

I want this. Badly. I can find no source for such a thing online (Jenvey has a nice one for something, but I'd have to make a base plate anyway and it's like $1500. Not an option.

Anybody know of a source for something like this? I'm already thinking about how I might make one using a base plate that bends in the front to attach an inlet nozzle to, with a custom lexan or plexi "cap", which I may be able to make by shaping a form out of wood which I can pull a sheet of heated acrylic over.. Anybody have any experience forming clear acrylic?

Maybe something like this (but I would heat the acrylic at 300F for some number of minutes to soften it, and not broil it like video)

All due respect to the quality of your air box, but why set yourself up for massive flow awesome only to suck air in through something less than ideal?

I mean the airbox isn't the hard part of your build. You wouldn't put all season touring tires on it, would you?

Thanks for the pic of the underside of the intake Pinky, I see what you mean now. And I have to say if that linkage were on top it would be awesome, underneath no thanks.

I will be making a blatant ripoff of your airbox in the near future...

Pinky

I'm not sure what you're referring to as "less than ideal"..? The airbox you used as an example is a box which houses a filter which draws air from a snorkel positioned to capture cooler then underhood air. My setup is a box which houses a filter which draws air from louvers in the hood directly above it positioned to capture cooler than underhood air. Which also incorporates heatshields to keep the box itself as well as the brake and clutch master cylinders away from the turbo's heat. Win, no? Especially when I remake it with the improvements I cited in my Sweet Box thread. (Folded top edge for stiffness, more elegant heat shielding, weatherstrip to seal it to the hood.)

'splain please..

Tuning the linkage would be a whole lot easier if it was on top, but I am guessing they were interested in a clean looking package.

Make a dished baseplate in whatever material you like and then add a halfpipe of acrylic heated/glued to whatever form you like. The edge would need some clamping force to keep tight (someone can calculate the force per psi if they want).

If the IC tube should be fixed in the baseplate or the "lid" is up to you, but having one straight flange would make it easier to keep tight, I assume.

This is my home-brewed baseplate with some depth, for inspiration in any direction (not make to keep pressure)

considering that ihi turbo flows and holds less pressure than a good fart, he'll probalby be fine with it as is for a while until he upgrades to a man turbo lol

Lol... Propped.

I hate to say I but I don't think an acrylic plenum is going to hold any boost.

with vibration, heat and pressure it will just crack at the flange. even aluminum cracks at the welds sometimes on custom inlet manifolds.

The location of your intake is great. I have no quarrel with that or the heat shielding and think you should keep both.

BUT

Instead of putting a filter in there that just sucks air in directly, here's my suggestion based on my understanding of airflow:

Look at the horns on your throttle bodies. They are expanding horns that curl outward at the end like Dizzy Gillespie's pipe.



This reduces flow restriction at the intake by making the effective flow velocity near-zero (as the opening diameter approaches infinity at the flare extremes). The lower restriction means air gets in more easily.

THEN: you pipe that air via some large duct (3 or 4 inch or what-have-you) to a very large space with a monstrous filter (again, more surface area reduces flow restriciton without sacrificing airflow as much). Pipe that filtered air back down to your turbo inlet.

In an ideal world, you'd have a horn like Dizzy's anywhere air has to change geometry (such as from a plenum to a pipe) to keep restriction low. Again, this is exactly what you'll have on your throttle bodies in another plenum. You're just doing it a few times in a few plenums: Hood, filter box, throttle body plenum.

A side effect of this is also a SUPER quiet intake. Because you're reducing the edge effect turbulence of that intake, you won't hear all that sucky, wooshy noise as the air tries to go around corners and crashes into stuff.

Unfortunately I know this is the Real World and that you Already Have a Box Design and I am merely Splitting Hairs in terms of adding performance. (I am also Unnecessarily Capitalizing stuff)

Is it still part of y8s dream turbo build with IRTB and plenum? YES. Am I funding it? NO! Hence all my typing simply boils down to unsolicited advice.

Jesus, it's about time somebody asked that question!! I was expecting major controversy and criticism, so much so that I actually mentioned to Eric (the seller) when I picked them up how much I was looking forward to the inevitable flame fest...

And then you ******* were nice and cool about it.. I'm a little bit freaked out; you guys have gone soft.

Short answer; it's Aids, through and through. Sure, it will probably make for a nice immediate throttle response, and could probably make more horsepower if I was running a head that was capable of utilizing the additional flow capacity, but I'm not. Yet. Right now it's because ITB's are Teh Secks, and it's sort of different. But no doubt, in my current configuration (stock head and a Cracker Jack prize sized turbo, it's Aids. But it's temporary Aids, just a stage in the overall development of what will surely end up being Not Aids.

I was just nice because you're not a noob.


Also: I can't say i haven't thought of this before, and may have a set of gixxer 1000 throttles tucked away for future retarded-ness.
