I was at Seven Stock today. They were showing off the air intake. News is about the same, they are still waiting for their casting guy to get with it. It is a nice unit. Similar in construction to the stock unit (plastic box) but the filter inside is a HUGE K&N cone-type filter. Looks like a nice piece.

 

The filter is really more cylindrical than cone...either way, there are some nice pics of it in the multimedia forum here

 

Yeah, cylinder/cone not to into geometric shapes. It's not oval like the K&N unit, and it's not like the stock flat filter. In talking with the guys at the RB booth today they did say their design is specially made so it is not too loud, and will not have the rough idle issues that some of the other manufacturers have had.

 

They said 3 HP across the board gain... :P Hmmm...

 

so did they actually say when they are projecting it to be avaliable to the public?

 

In the Rotary Tuner Magazine they said they are looking into FI for the 8. Did anyone hear anything about that or ask them about it?

They did say that FI was much further down the horizon.

 

Ok, I was there and asked several questions.

I also showed up for their open house today, Sunday 9/12.

All I can tell you is that I am confident in the Racing Beat team. They have booked orders from several distributors. Expect to see this soon in 1 to 2 months.

Being quite with HP gain is great. The workmanship, dedication and persistance to make a good product has yielded a qualiy product with performance.

A positive air pressure in the unit has been achieved. The competetion can not claim this.

Expect to recieve a good product with good results to the real wheel.

If want performance, quality and the ability to meet EPA regulations go with Racing Beat.

If your looking to trust a manufacturer and their products, you won't regret purchasing parts from the Racing Beat team.

 

Here are the photos I promised. The first shows the intake in a cutaway of the whole box. The second shows the same piece with other cutaway part, and a full unit in back. The third shows the full unit (engine side) with filter inside. Last shot shows the unit from the front (air scoop side).

I could not get any information about price or availability; I even tried to pre-pay for one...they just don't have the info yet. I gave my name and number to them to call as SOON as it's available for purchase. This is one nice unit!

 

The air filter inside is pretty good sized; about 8 inches across by about 10 inches deep. That's just an eyeball estimate; I didn't actually measure it. Can't wait to hear what it sounds like installed. I have their exhaust and it's just great.

 

Not to throw this topic off course, but where can one purchase that Seven Stock t-shirt that guy is wearing in the picture?


Intake looks great. I can attest that they make a high quality product as I have Racing Beat's intake for my 99 Miata.

 

wow...looks like it will be pricey...

 

It's a nice intake. Just the one I would be looking for; the airbox design is my style. I'd rather have forced induction more than anything else.

 

Try the sevenstock site. I didnt look for it, but check it out.

They said the shirts were all sold out this time for SS7. Perhaps they may make more?

I'll put mine on Ebay then... j/p

I agree with Razz1 on this... Racing Beat definitely impressed me with how much they knew about Rotary, cared about Rotary, and the facilities in general was enough to show me that they run a good business. Now, only if they can make me the Racing Beat exhaust without the "Anaheim, Ca." Stamped on the side of it! ack...

 

i dont think it would be all that pricey...

RB makes a similiar intake for the 3rd gen RX-7 and it only costs $97...without the filter that is

 

The 3rd gen "intake" is just a plastic duct thing. Its not an intake at all, per se. I'm sure this one will cost significnantly more. If not...I'll buy two! :D

 

After seeing that intake, I like it. That's how it should be done. I chatted with Jim Langer at RB about it for a while. The key to getting a good idle and good response from an intake is in the maf tube duct length. Their tube to the maf is slightly shorter than the others but they use a deeper filter. They had 2 different cone type of fitler elements that but which one will be the final one is yet to be determined. Let me just say this is not your typical cone. It is big. I like that and this is one cone that I will approve of. The intake tube leading to the airbox will be a ram air type of tube without any form of VFAD. Since the key to airflow is after the airbox, anything they do before it will not affect the maf reading. This makes it possible to use a ram air system with the air inlet in the front of the car. Good job guys! This is still not the final piece but it is close. It is also very quiet.

Early in the day they ran a Renesis on the engine dyno for us. It had a completely stock RX-8 exhaust system hooked up to it. It had a K&N intake on it though. This thing was screaming loud. You could hear it down the street! They put their system on the dyno later in the day but unfortunately it was after the event so we didn't see it. They wanted theirs to be much quieter than the K&N but a little louder than stock. They still say there are only a couple of horsepower to be had from even their intake so don't believe any big claims from anyone else. After seeing their shop and talking to their people (Jim Mederer is a god!) I am absolutely convined that they know what they are doing. Anyone in the market for an intake, wait for theirs!

 

RG-approved! I'm waiting ...

 

Hey RG, or anyone else...are we losing anything by doing without the VFAD? Didn't that help "tune" the stock intake to work most efficiently at both low and high rpms....if we replace that with an "untuned" ram air duct, won't that be optimized for high rpm, high speed driving at the expense of slower speeds and lower rpms?

It just seems that this (and all of the intakes so far...this seems to be the best, but its still a similar design concept as the rest) is a simpler design than stock. Why would Mazda go with more complexity if it gives no benefit?

so i guess the RB intake isnt a CAI despite all the rumors and such...

 

I think Chuck Huang from Rotary Extreme covered this pretty well. This car will be very difficult to get a true CAI for as it has a MAF sensor, and would have some severe issues with a CAI (which would work better with a MAS sensor). That is why many/all of the designs so far have been a modified box/short ram intake design.

 

The Racing Beat intake WILL be a cold air intake. The intake tube just wasn't there to be pictured. The pieces were only delivered to Racing Beat on Tuesday. They haven't finalized the design yet.

Their design isn't just a long tube that is attached to the maf. The length of the tube that the maf is on is the key to tuning an intake. There is an air box in front of this where the filter is located. Leading into the box is the long cold air tube. Since this isn't the same tube, it doesn't affect the maf readout. This is how I have said to do it for a long time. Just take a short ram kit, put a sealed box around it with a tube leading into it. It won't affect the maf. Chuck didn't do it this way. His long tube was the same tube that the maf is on. This is why the maf was sending messed up signals. If you think about it, your car comes this way from the factory. Same sort of thing but with better flow.

 

this intake is REALLY nice! pretty much you guys have covered everything about it. price will be out in a couple of months. its correctly sized, well made, will sound better than stock but wont cause you to go deaf, wont have any idle issues or other mafs issues. one thing not mentioned is they had k&n design and make the filter for them. they have spent alot of time and energy to make an excellent product. i have alot of respect now for racing beat after spending the time there on sunday.

 

And also, you can utilize the existing engine cover. Their box will include the grommets for snapping the engine cover in place.

 

I'm also a fan of having an actual airbox - the larger resevoir of air in the box usually provides for a bit crisper throttle response then a long tube from my experience
