I've had my REVi+air duct on for a few weeks now and I finally tracked my milage. I averaged 20.29! While this doesn't sound great, keep in mind that I'm coming from 17-18mpg. It was mixed driving, some full throttle starts and a touch of hard driving. I'm very pleased with my intake.

 

Lucky bastard

 

I have experienced the same kind of increase in mileage since installing the REVi and RAM kits. I've been seeing between 20 and 21 mpg of which all is in-town driving. Interestingly enough I've seen the mpg increase inspite of more frequent runs to high rpm so that I can enjoy the new intake sound which has resulted from installing the kit. So is the mileage increase the result of the new intake or the change in driving habit? I don't know...not sure I care....

 

lucky bastard is right
I get around 17 with my K&N

 

Where do you get the REVI? I searched and couldn't find it although I am sure it is there.

 

Racing beat (the sponsor of this subforum) makes the intake. You can get it from them or go with mazdaparts. Mazdaparts is a forum vendor here and they have a nice price if you become gold.

 

anyone know where the cheapest placed is to buy the intake? i'm definetly would like to increase on my 20-21 mpg.

 

The place I got mine from has since raised thier price.

 

Since I'm a noob, what is gold?

 

Go on mazdaparts sub-forum. Actually heres the link https://www.rx8club.com/mazdaparts-com-90/rx8club-com-member-discounts-47923/
Start and account and ask to be be gold.

 

Thanks, I will do that. Is this the best intake for improving MPG?

 

Most people on this site will tell you to buy the racing beat REVi, there are a few people who wont. I personally have it and I like it, I too have been getting over 21 MPG since I installed it. There are a few places that sell it. Check these stores out

I'm getting 11 mpg...
I wonder if the REVI will give me 21 mpg....?


Ya, In my dreams...

 

Ha Ha.......

I just got 22.94
On the way home I even got more 23.5

Don't ask about the mountain run..

 

Holy crap eyeball... How do you get 11? I drive pretty hard and it's hard for me to get 15! >.<

 

I would like to see some sweet #'s like that
may have to sell my R.E intake and go for a Revi now

 

100% in-town driving under 40 mph = ****-poor-mpg!
I've been fighting with my Strealerships Service Dept for months and just sent a
bitch letter to the President and CEO of Mazda North America Operations "JAMES O'SULLIVAN ".
I sent it in an Office envelope (medical) and marked it "confidential", I hope he'll help me!

 

Lol, that's a tricky idea there Eyeball... he's gonna freak and think it's his test results or something, lol.

 

I got 25.7 mpg with a K&N drop-in filter -shrug-

 

I got just over 13 (all city) with my first tank but I am hoping for about 15-16 city wen the motor breaks in. Maybe with the Revi, I can achieve that 18 on the epa sticker. Will it void the warranty? Can it be chipped or remapped to improve mpg w/o ruining the almost linear power curve?

 

I was getting between 14-15 mpg pretty consistantly for the first 10,000 miles. I did get 19.8 mpg on all highway once. Then the motor broke in and I got the R flash. My next tank was all on track at Watkins Glen, and I got 6 mpg :D
However, I picked up ~3 mpg on normal driving upon break-in and R-flash, as well as the hotter spark plugs. Since then, I've gotten the B&B race pipe in place of my cat and I think I picked up another 2 mpg or so! This is getting to be similar to a big SUV with rather GOOD fuel economy! :D

 

Uh...huh?

I'm extremely suspicious. I'm SURE there's no mischief here, but the sponsor of the forum manufactures a product, several random people pop up and claim a 10+% increase in fuel economy from a simple intake replacement, and provide all the links and info on where to get your insta-fix right now.

Maybe all is at it seems, maybe it isn't....I'm just saying....

 

It would be suspicious if some of these guys werent frequent posters all over this forum, I think I have even argued politics with a couple of them a few months back haha.

 

I've had my RX for a year and a half and my driving pattern is exactly the same now as then. Awful stop and go on I-66 in Northern VA. I consistently got 16.5-17 mpg since I've had my car. I put in the Revi and duct a month ago and the last 3 tanks were 19, 17.9, and 18.3. So I'm 100% convinced that it is helping. Funny thing is I wasn't really looking for mpg improvement. Just a few extra hp and nice sound. So I'm quite suprised and happy with the results.

 

I got 8 MPG with my REVi and Ram Air Duct...







Of course that was after 129 miles Tuesday at Watkins Glen :D :D :D

Seriously, can't say that either impacted MPG for sure. I think I saw an improvement with the REVi since I have hit higher MPG on the highway with it than I ever have before. Haven't really seen any impact from the RAM Air Duct - beyond a mellowing of the sound of the REVi alone.
