FujiRacing IRTB Air Box

4 Throttle Tuning · 02-18-2008, 09:17 AM

You all are the first to hear this. We will be releasing our IRTB Air Box soon. It will be TIG welded-hand made and it already is on a customers Miata. No pictures until the release date, and I am looking at up to $750.00 retail. Quality will be second to none.

If you want I do not have a problem with you guys posting pictures of what you have seen on air boxes and then you will see ours.

freedomgli · 02-18-2008, 09:23 AM

When you say it's TIG welded I assume it's made from aluminum? Does this mean FI + IRTB?

avante43 · 02-18-2008, 09:36 AM

So when is the expected release date?

Also, will the inlet for the airbox be located in the same position as the stock throttle body?

I would assume its aluminum by the price tag also. Most fiberglass/resin/composite IRTB air boxes run around $300. But they can't handle FI, they're more for plumbing purposes.

One box will be for NA (first to be released) and the FI one will use a thicker grade material for the pressurization. I am hoping to release these within 1 month or 2 at the latest. The last post from Miatadam is correct from what I have seen thus far. Our design was carefully thought out to be able to utilize the longer airhorns if needed.

Will they clear the washer bottle? Chuck

LostSoulMiata · 02-18-2008, 02:25 PM

So is this a custom built to order thing or is it based off of what works best for you Jimmy?

It's actaully do to one of my IRTB customers and the box is sized bigger than what I have seen with other boxes and the washer bottle will have to be relocated. It's what we hope will work best on a Miata.

leatherface24 · 02-18-2008, 07:08 PM

Jimmy and I have spoke about this thing. I have high hopes that im sure wont be let down

ab7 · 02-18-2008, 09:55 PM

Jimmy , what's better in term of performance?
ITB with socks or with box?

freedomgli · 02-18-2008, 11:06 PM

9 times out of 10 a cold air box would be better for performance. Socks aren't so good as they spoil the airflow around the air horns.

Greg G · 02-19-2008, 01:18 AM

Arrrgh I hate suspense !

4 Throttle Tuning · 02-19-2008, 05:28 AM

My thinking use to be no air box was the way to go from what I had seen since the air boxes were too small. On our box the cold air will be coming in smoothly and you will be able to use the longer air horns up to 110mm for low-mid range torque. The key is cold air + utilizing the air horns.

leatherface24 · 02-19-2008, 08:43 AM

when you say cold air, do you mean that the box will have an intake tube plumbed to a cooler spot in the engine bay or just the fact that itll be blocking out any hotter ambient air just by closing off the itbs from taking in and more radient heat from the engine?

Alright I will say this. "Cold air is going into the box and when I saw the finished product I about fellout of my chair." It's happening because of one of my customers and I have never seen anything that nice IMO when it comes to air boxes.

...like drawing in air from behind the firewall?

LostSoulMiata · 02-19-2008, 11:16 PM

So is it tapered for better flow to the furthest away throttle body, or is it just a single one-size diameter plenum?

Air is coming from the front of the car and the box is not tapered because from our testing we want to utilize the longer airhorns.

Matt [exz3owner] · 02-20-2008, 07:54 PM

what tests have you done?

for a FI box, most flow benching on other applications show the need for a taper.

curious to the net power gains in fi configurations...

cool project jimmy.

The first box will be for NA and Anniversary's box in Japan is tapered I believe since he has done IRTB/Turbo. If we need to make a tapered one for FI I am sure that that could be managed.

It's killing me but when I have been requested not to release it yet from one of my customers I have to and will honor that.
