Well as some of you know, RxTuner will be testing out some RB parts on the dyno.

This will be the thread to discuss.

Below are some pictures of the Racing Beat intake system. And me digging through it.

Nice.

I liked the RX Tuner turbo coverage, but I think a good set of performance tests on the greddy would be nice to see such as 0-60, 1/4mi, new dyno etc....

There was a After dyno in the Greddy Turbo article, I proposed to Jon to let me drive his car down the 1/4mile, since we all know I can run a 14.5 in stock form, but its not something I can force him to let me do, beside our time table didn't allow for it.

As for the RB Intake:

A baseline chassis dyno will be done, most likely at KD Rotary, then the RB intake will be installed in shop and dyno'd again to show any gain. Next, we will install the exhaust system in shop and once again redyno'd to show the gain both systems make, again driving impressions will be done, noting the volume and "feel" of the systems combined.
After driving impressions, I will take the car home, put it on the lift and install The RB flywheel along with a MazdaSpeed clutch, I do not expect any "measurable" gains here, but the car will be dyno'd again and comparisons of the torque curves will be done.


UPDATE (DYNO)'s
RB Intake and RB Flywheel+MS Clutch and PP Dyno's below

Well sorry for the off topic but i have ms fly and i am going to buy the ms clutch+cover and was thinking to take a lighter fly like the rb..But how much is the stock fly for real??Would it be big difference or i better leave my ms fly as it is??

Anyhow..
I am really interested in the dynos,so keep us informed..i have ordered revi,i have ms fly and waiting for canzoomer midp-4 and ms clutch...i am anxious!!!

Hey Polak, I read your Zoom Zoom Psst thread, GOOD job. I'm looking forward to the dyno after RB intake installation. Mine should have been ordered by now, but the wifey felt it was more important to use my mod money on flowers and plants for our yard instead

keep up the good work.

Got the intake dyno'd, WONDERFUL system worth every penny.

I just got back from Rotary Revolutions I'll post the dyno tomorrow, LOT of MIDRANGE GAIN, even has a more stable feel then stock, I couldn't be happier, worth every bit of the 300 bucks.

Adding Flywheel and Clutch/PP this week hoping to get close to the 200rwhp number with those on.

army_rx8

i wouldn't think you would see 200whp off a flywheel...well unlesss you dyno teh car in a lower gear, where you would see more of a gain (yes i know it does't add any thign just frees up hp..that's what i meant :p)...well unless i am totaly missing something :D which is likely. lol.

anyways...i lov emy mazdaspeed flywheel and RB clutch and pp. you shoudl find the acceleration really fun after you do that Polak...good luck and thanks for all teh fun and informative articles :D

ARRGH!! You tease!! :p I can't wait to see these results! I was going to do my own before and after, but the dyno shop refused to cut me a deal on the price. I just couldn't see spending $55 a pull for the answer. I decided to wait until I have a high-flow cat and do the dyno on the whole system. I can't justify spending an additional $110 on each mod just to measure the gains - especially when the true measure of the mod is in the pleasure you take from it - regardless of dynos! In that regard, I have to agree. The RB intake is a bargain! I LOVE IT!

You may have not been there, I didn't get there till sunday because my plane had to make an emergency landing.... long story just one giant cluster f*ck basically.

As for the flywheel lets leave all the debating aside unless someone wants to put some money on the fact that I will crack 190rwhp with it, the stock baseline was 177 this time around in 3rd and 5th gears. I'm using 5th to compare all the intake stuff, and incase thats too high to show any flywheel gains I have a stock 3rd done.

dmp

side note: does it **** anyone else off that renwar1's car dyno'd 200whp STOCK...and the rest of us have to spend money to get there? lol :D

Great stuff, PoLaK...It'll be great to see the before and afters..

Told you it had nothing to do with it being in 5th gear.
I'd like too see him on a different dyno tho as I recall you all were making above 180's right?

dmp

it has everything to do with being in the right gear - if you want accurate, repeatable results

Yeah - we four or five were making mid 180s, regardless of mods. Not sure why us making mid 180s has to do with his car making substantially MORE, however.

He had a couple 198s...then one 206. Later - weeks later, he'd dropped some 8 or 9 hp; mostly due to weather, iirc...

Still - shows concern to me; mazda can't seem to make a consistant product with all the power they claim.

Well duh, but acutally making the "200" number had nothing to do with being in 5th he coulda done them all in 3rd and gotten the same thing.

Btw its just a number on one of my dyno runs I spiked to 680rwhp, doesn't mean my car is making 680rwhp nor does the 180, 190, 200 mean that that car is making those numbers, its usefull as a tuning tool thats all!
If you all were making 185 then its reasonable to assume that the dyno was a tad optimistic but there is no doubt his car was making more power, what the "real" number was is unclear.

Lemme go take some screenshots.

dmp

No..because he did a 1-6th run...and he only hit 206 in 5th gear.

Except this wasn't a HP spike...it was a HUGE curve, with gains higher than the rest of us at just about every point in the rpm range. It can't be dismissed as such.

doesn't matter how accurate or not the final numbers are - what can't be explained is why his car made SUBSTANTIALLY more power - peak and 'under' the curve.

dmp

oh - and didn't mean to hijack your thread, bro. Sorry.

Its fine I'm always up for a **** in the wind.

Anyway I have a little issue does anyone have a really old version of the Winpep or Runviewer software?

I got the .DGP file of my dyno runs but failed to remember that Dynojet (TM) stopped support for this type of file years ago when the upgraded the software, currently they use .DRF files.

I'll have to get the .001 .002 .003 individual runs when i dyno the flywheel if no one has an old version of Runviewer/WinPEP, that means more wait

IZoomZoomI

weak sos....

MadDog

Any progress on this? The suspense is killing me. RB has been alluding to the fact that the dynos will be nicely surprising. My butt dyno tells me the same thing.

You know how a picture is worth a thousand words? If you can't get the picture I'd settle for about 100 words (and numbers) :o .... :p

^hehehehhehehehe what he said :D

DARKMAZ8

polak--please take your car to the track! I don't trust the 8 on dynos. All the previous fc n/a dynos indicate a smooth linear line all the way up to redline. Something doesn't look rite with the 8's dyno graphs. Since you already have a base run in your 8 in the 1/4. Just take the car back to the track and we'll compare the trap speeds.

dmp--If you watch the star mazda series, the anouncers always state how each car is equal because it is a rotary. I don't believe that one guy has some kind of mutant 8. Tell him to take it to the track too.

zoom44

i dont understand how you have a file you cant open or whatever since you just got the dynos done. cant the dyno place give you whatever you need? do you have printouts from them you can just scan/post? did you try to google the software?

PoLaK

iTrader: (1)

Like i said the shop didn't give me each individual run IE .001 .002 .003 etc... (which is openable in any version)
They gave me a .DGP file, which was replaced by .DRF (dyno run file) several years ago when the winpep software was upgraded. KD rotary still uses the old software, the dyno computer in the shop isn't hooked up to a network nor am i going to trouble them to transfer the file over to the other computer and then email them to me, I'll do it myself when I go back for the flywheel and clutch dyno run.

No I don't have any PO's im sorry, I'll see if Dynojet INC. can help me out.

Are you telling me that you would be more inclined to believe a comparison from a 1/4 mile run from 9months ago that was done in 90deg heat, compared to the 65deg it is now. That is totally dependant on driver skill and luck, not to mention the fact that we are talking only 4hp peek and 7-10 in the midrange which would translate to a tenth of a sec or 1mph, if lucky and if i managed to perfectly launch the car like I did? Additionally I would have to have the exact same amount of gas in the tank as not to give or loose an advantage?

Are you telling me that this would be better then a same day, only 1 hour apart dyno run, the car didn't even change positions on the rollers (we installed the intake on the dyno then let the ECU learn while just driving on the dyno)

While I do not believe that a dyno shows the exact number the car is making, but ran 3 stock base lines one in 3rd and two in 5th and each was 177.X RWHP SAE, thats as close to repeatable as one can get unless you wanna help me take the motor out and put it on a engine dyno.
