Yeah, but you see the way I drive.. I always keep it in the power band.. That's where my crappy gas milage usually comes from

dmp

I also felt like I was a shark -lurking the streets, hoping to catch a 'fish' (read: civic, mustang, etc.) who'd wanna 'run'...do you find yourself driving the long way home, in hopes of layin' some smack down? ~250whp in a 3000lbs car is a recipe for success, in most cases.

I knew that, but I had the position of the MAF all wrong in my head. The MAF is upstream of the turbo isn't it? Makes sense now...do you use a MAP sensor with this kit as well? This has probably been answered already...I thought I was keeping up with the thread but its growing exponentially!

I saw the video last night and I can't really judge it much since I have not pushed my 8 yet but it sure looked fast. I hope now that I saw Philodox's 8 I wont be disapointed with mine, but I don't think I will because I love it now even while babying it.

Some notes, questions, etc?

Phil, do you even use 4,5, or 6th gear? LOL...if you are complaing about, IF, fuel economy then maybe you should not cruise around town in the high 4K range all the time? LOL

I wish the sound was better because I could only hear the wheels, rotary burble, and "psst" Turbo sound just slightly over the guy in the back seat typeing a 500 page book, LOL. What was that constant clicking?

Mazdaspeed short shifter? I thought the RX8's shifter was already short...gosh, I'll have go go check it out.

Again, thanks for taking the risk and putting in all the work to bring us into this experiance. I hope your Turbo last for a LONG LONG TIME! Enjoy it and be careful now with your much more powerful RX8. Oh yeah, good luck on your test!

Predictions? Anyone have any? IF, Phil's RX8 is making 300HP at the flywheel then per the power to weight ratio it should be faster than the new Mustang GT (with 300HP @ 3500 pounds). Is it safe to say this?

RX8 with 300HP @ 3055 pounds vs a Stang with 300HP @ 3500 pounds should = RX8 the winner

13.5 1/4 should be the benchmark but I would suspect low 13's to come from this Turbo RX8. Keeping in mind tranny/gearing, lack of traction, etc you should be able to beat 13.5's. What does everyone think?

13.2 is what I expect if not slightly better

Phil, you might want to get fatter tires in the back to help your times. x by 9 should be good.

Thanks again for shareing and don't listen to Richard Paul...he has some issues...

Reminds me of the movie "Groundhog Day"


How wonderfully Xtian of you.

for what it's worth... 'predictions of power' are pointless...even worse, predicted FLYWHEEL HP...in a practical sense, Flywheel HP is worthless, as a number. Most of the time, people say things like "...and I estimate that to be about 300 at the crank" becuase the number '300' sounds more impressive than 'i've got 250 (or 275, or 200 -whatever) at the wheels..."

I applaud John(John, right?) for not being overly excited about predicting numbers yet... A couple of guesses, sure...but when we start magazine/numbers racing, it's borderline ricey.

:D

Petrus

Yes, You are correct... The 8 is a short shifter from stock.

twospoons_

The quarter mile slips should give us the information we need to know about "real" hps.
Then to see some dyno runs to see how it all hooks up. Dying to know how the torque
looks.

But it's always fun to speculate. Even though it only creates hype and
dissapointment. :D

philodox

Yeah yeah.. I know.. I hear enough from Mark (Polak) over IM. :p

Sorry for the clicking.. the lens cap to my camera was banging against the tripod I had bungee corded to my drivers seat.. I'll be sure to secure it properly next time so we don't hear the clicking


Yeah, the shifts from the MS Short Shifter is a little over 1 inch less from gate to gate. I love it. Looking foward to Richard Pauls shift kit though, his is solid aluminum which gives a better feel. The MS Short Shiter has a lot of flex in it.. still good, but could be better if the MS shifter didn't have flex in it.[/QUOTE]


You and me both! It's a totally different car. It's a bit harder to drive when you get on it, especially since it's so easy to kick out the back end. I'm starting to get pretty good at modulating the throttle to prevent too much wheel spin.



Yeah guys, I'd rather not speculate on anything until I can PRODUCE hard numbers. Stay tuned for those. Should have them within 2 weeks.

We'll see




Well, my winter tires are sized 255/40/18 in the rear. A little wider, but not by much. See above /\ responce for my thoughts on speculating, I think it's best to wait until I can get hard numbers for you guys



Well, when I was in the military.. we had a saying.. "Assumption is the mother of all F#$K Ups".. Hopefuly the weather holds for this sunday and I can get to the track and get some 1/4 times for you guys

dmp

I like you. Very nicely put.

philodox

Well, just went out and got another part for the turbo.. This time it's a GReddy Oil Catch can. Not only is it useful But it dresses up the engine bay a bit more.. hehe..

another8owner

we need to start a new forum section for FI RX8's, w/ member lists and call it The REDLINE Club. and the only way to become a REDLINER is to put FI on your 8. give them a special avatar badgeing or somthing.

Jon,

Have you checked out Racing Beats Metering Oil Pump modification for you 8 now that it's turboed?

http://www.racingbeat.com/FRmazda4.htm

another8owner

pic?

philodox

Yesterday I said I would post pictures of the mod I did to the AIRINX filter that comes with the GReddy kit. Here they are. What I did was disassemble the stock intake box. I took the 2 wire mesh screens out. I used an industrial strength epoxy and glued the two screens together. Next I took that and attached it to the inside of the filter itself. The pictures explain everything.

Reasons for doing this. Well, for one.. the stock intake has these right before the MAF sensor. I believe they help "clean" the air and make it less turbulant as it goes over the MAF sensor. If the air is too turbulant going over the MAF sensor you can have very rough idle problems. I'm sure some of you with the SR Motorsports or K&N Intakes know what I'm talking about. Putting these screens on the AIRINX filter solves this problem. I was having the occasional rough idle but now that is gone now that I've done this little modification to the AIRINX system.

philodox

for the oil catch can? I am waiting for it to be delivered. I just bought it today. I'll post pics when it gets delivered and I install it

davefzr

What are you made of money haha.. I would sure love to be able to peal off 100 dollar bills anytime I wanted... Just sucks if you have to wait for it to grow back...

I'm not sure why anyone would do this since you can just bolt on the MOP from the low-power RX-8 which already flows more oil than the hi-power version.
Cheaper, too.

The other reason the idle might be rough on the Greddy kit is because the MAF is very close to the filter.
On the OEM application, there is more distance between the filter and the MAF, giving the air flow some time to become more cohesive.

I put a lot more distance on my suction pipe:

What now? Well, what ever you meant really does not matter anyway. I’ll move on…

I understand that, it’s just what the manufacturer’s use flywheel HP so that’s the number I wonder about. I understand that whp is the better indicator.

I asked for predictions in fun, not to hold it against him later on. That’s all…

So that's what that was, me and a friend where trying to figure it out. I thought you brought along a reporter who only had an old school type writer or something…LOL

I can’t wait for more and more…keep it coming Philodox…

Mr. Ed's rx-8

how difficult would it be to relocate the battery to the rear and then get a different intake pipe to run that way. just trying to figure out ways to open up the engine bay a little.

philodox

that's exactly why i put those screens there... so the MAF can get accurate readings

RX-Nut

Is that your exhaust popping like mad? Is that normal, has it gotten more "poppy" with the turbo?

philodox

Yes, that's the exhaust. It's totally natural for a turbo. It's more apparent with a rotary since they are prone to "popping" already. What is causing that is unspent fuel finding its way into the exhaust system after letting off the throttle. Nothing to worry about. Kind of gives the car more 'character'. If I ever remove the cat and go straight pipes, I'll be spitting out flames like crazy

zoom44

that is something that Racing Beat found also when developing their intake. the distance from the filter to the maf was essential in keeping the idle smooth and the MAF readings accurate. one of the things they talked about at 7stock
