That is why I am doing two of them at once. I am most nervous about taking the nose of my car off. People say it is easy, and I have worked on my own cars for years, but there is still something a little unsettling about taking the front of my nice car off.

Mikelikes2drive

it was pretty simple taking off the front bumper... just a punch of those plastic clips and 10 bolts underneath the car. The biggest problem i had taking off the front bumper was disconnecting the fog lights :/ i know it may sound stupid but i scratched my arm up alot tryin to get that sucker out.

How is the gas mileage with this new Rev-i intake? Did it improve over the stock intake?

TheDosDog

I monitored mpg on my CanScan before and after the install. There was not a detectable change at freeway cruising speed (65-70) 24.5 - 25.5 mpg

They were suppose to update the instructions to tell you how and which way to pull off the fog lights.

Just got back from my first test drive - wow is all I can say. With my mods this intake rocks! Idle is stable, cruising around town I was barely touching the gas which was sweet - I can see improved MPG. And then WOT was... well, I'll let you make your own conclusions. All I can say is awesome.

Word of caution - be careful with the o-ring around the MAF. I had a similar experience with the SR Iintake if you remember that old thread...

rotarygod

Everyone already knows my opinion so how do you like it compared the the SR intake?

The SR Intake was a lot louder and I had trouble getting the SR to seal up properly. It was a nice intake, but the MAF tube did not have the correct length, and did not have the bell mouth inlet - which I think is extremely important for proper flow characteristics from an engineering point of view. The SR did not have the mesh screens either, so idle issues could result.

The RB Intake has a larger filter surface area; it is by far quieter also. This intake is highly engineered - nice quality. Reusing one of the mesh screens was ingenious. The inlet is a little strange with it ending right at the frame opening. The supplied foam donut sealed this connection and it was tricky to keep in place while reaching into the intake opening to tighten up the mounting bolts. Other than that, I forgot to reattach my fog lights, so I had to perform exploratory surgery with my hand and reach through the grill to re-attach them. :o

I'm very happy with the intake - Good Job Racing Beat!

On the tube that the sensor attaches to, there is a cut out that does not appear to be very well finished... does this look normal?

Yes, mine looked the same. Don't worry

Think of it as weight savings

Would it be a GOOD idea to also remove the black piece under the air inlet duct to let more air flow in? (hope i'm clear)...

Nemesis8

iTrader: (3)

I did

SilverBullitt

I want to remove it. I think it make sense, but my concern is about the hood presure with the wind... would it or not really ?

ranger4277

I have removed it as well, no probs.

What I'd really like is to take the black plastic thing off the nose of my MS front end and replace the area behind it with an air collection scoop (sealed for better pressure) and channel all that air towards the intake. Guess I'll wait to see what the RB CAI addition is like before I custom make one of those.. not that it matters too much since I don't even have the intake yet. :p

zoom44

there's plenty of air getting to it already by going up around the sides (just like it did with the stock pieces). i think the main reason for that piece is to keep water from splashing directly up into the intake. i figure tho that at least part of it if not all of it will have to go once RB comes out with their ram piece.

I thought about the water issue also, so I looked for water spotting on the underside, and saw none - so I left it off. I guess I could always put it back on if needed.

Ok guys listen to this. My friend Charlie who owns Mazcare just dyno'ed his 8 with this intake. Baseline dyno at 1200 miles (in 5th gear) was approx 186 some monthes ago. He has since added his own custom cat back, (almost like racing beats) act prolite flywheel(doesnt add h/p), the n flash, underdrive pulleys(did not feel that added anything. he yesterday added this intake(oh by the way he is a RB dealer) and this is the results of his dyno in 5th gear----ready----you sure-----(i know some are going to have all kind of disbelief's--- Ok here it is------- hp 201. something and get this TORQUE of 142! Now dont flame the dyno on differant days etc. This guy is a professional Mazda mechanic with years of racing experience and he says it's real. The power starts coming on at 4700 with a big jump at 8.5K. He will post his slip but he is packing for the Grand prix at road atlanata this w/e. This is for real guys! I get mine tomorrow!

I'm not busting nuts about the dyno after the RB intake was installed, because I have one coming too and I can't wait, but does he have a dyno with just the cat-back? How much power was actually added seperately by the intake and exhaust?

GrRx8MaZdA

Someone stock here was in the 200whp range..only ms air filter..Now he has trust titanium catback...I am in same with him but now i have revi-midp-4 and greddy sp2...I beliece i ll go more than 200whp!!!iI hope

GrRx8MaZdA

The catback can't make more than 4hp...For sure..But the combo of intake and catback can make more than just catback or just intake...

All --go to the South East thread and under HPDE Road Atlanta thread within the SE thread Charlies dyno sheet is posted . See for yourself! His name is Marietta 8

Charlie says his cat back was good for about 2.5 hp. I know you guys don't know him but the group of RX8 owners who get together for track days and HPDEs in Atlanta (check out the SE forum) all know him well. He is a straight shooter no bs guy and a rotary expert mechanic with years of experience including building RX7 race cars and competing. He also has many Mazda racing contacts and friendships with people the likes of Roger Mandeville and the Speedsource guys. If Charlie says it made a noticable difference, then it really did. And noticible is probably in excess of 5 hp. I am guessing there are gains to be had by having better exhaust that multiply when better intake is added. I am getting one of these damn intakes too. Glad my wife allows me to feed my habits...
