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.
