Free-Flow System complete~
 
Fellas...
pretty soon, i'll be running a free flow system to my 8. Hks Racing suction, Rotary Performance Super Cat Midpipe, Borla Catback... That's pretty much it for my performance upgrades...

Any suggestions? Please, no Canzoomer b/c i dont want to tune it. I'm talking about bolt-on's or immediate power. And i don't have close to enough for the greddy turbo ::sigh::

Anyhow, i also have a full ms shocks/springs and 4pt jdm Ms front strut brace. Does anyone have any suggestions?

And with this setup, Intake, RP supercat and borla, it should be relatively easy to spit fire right?? Am i on the ball here?

Any input would be appreciated.. thanks!

I wouldn't expect much more than maybe 10WHP total at the top end. and expect it to be really loud, as I have heard the borla/HFC combination already.

If you haven't already bought the intake and exhaust, I would just keep your stock ones, as they seem to flow pretty good.

Unless you want to port the engine, I would just save your money for the turbo.

I like to know how you managed to use a jdm MS front strut brace. The brake cylinder brace isn't on the right side.

Sorry to say your car will only be slightly faster than stock with full intake and exhaust. By no means a spitfire. Mazda just did really good with the stock equipment.

jaehyun127 03-22-2005 05:42 PM

the car already spits fire with a borla cat back... provided i switch to a Super Cat (high flow cat), the rich fuel mixture should make it very easy to spit fire...

As for the 4pt JDM MS strut brace, the MC brace is disregarded. The mastercylinder is just "chillin" there by itself, and there's like a little bracket for it on the passenger side for the japanese MC brace... Anyhow, the fitment is perfect and it is EXTREMELY snug. The strange thing is, the stock strut brace, is very loosely fit... meaning, without jacking up the car from the engine on the bottom, the strut just comes off... which confused me a little bit. I thought it would spring at least a little bit and i would have to use some muscle to take it off, but it just came right off no problem.

As for HP, i expect about 15... hopefully? B/c someone used the same Super Cat by rotary performance, and gained about 9rwhp, and borla... let's say like... 3-4 and the HKS racing suction unit is pretty good... so reasonably 2-3hp...

i would say 15 should be good. As for the noise, i love the sound of the car and i would liek a little bit of noise. The HKS racing suction unit is pretty quiet... surprise surprise right? So i found that pretty quiet, borla isn't too loud either, and the supercat.. well i have no idea how that sounds. But i'm waiting on it.

Any q's, feel free to contact me.

Also, for you canzoomer tuners out there... how hard is it to tune the canzoomer stage 1, and how time-consuming is it? Input fellas?

Feel Free to read Racing Beats Experiment with "Free Flow" equiptment before you get your hopes up for that 15 HP:

2. Headers – approximately 4 HP peak power gain.
3. Mufflers – muffler & connecting pipe - 2-3 HP.
4. Removing the muffler from the car (engine) – about 4 HP.
5. Remove catalytic converter and resonator from the engine completely, and replacing with "cat" replacement tube – max benefit 8 HP – regardless of what muffler is used (or even no muffler).

"The muffler "off" will yield about 4 HP, with a very loud exhaust note. With it "off" the car, the noise is unbelievable! We find 2-3 HP peak RPM maximum improvement from our exhaust, or any competitive system that we have tested. So someone can see from these numbers, it is quite difficult to get a lot more HP from this engine. The max potential with a header and race exhaust would be around 10HP."

you guys should be critics 'cause all of you are so harsh~

look up thread "super cat" and click on the one w/ rotary performance... it has like 10pages to it... and look at his dyno claims... they seem to be a good read.

rotarygod 03-22-2005 09:03 PM

We're not harsh. We're realistic and honest. Denial doesn't change that. I think a 15 hp gain isn't terribly unreasonable from doing full intake and exhaust. It might get close to that. The real question is will this be a gain everywhere or only at peak power? Since you need at least 10% gain in power (across the entire powerband) to feel it with any certainty, you aren't going to notice this small amount. It isn't any faster from a functional standpoint.

One of our fellow members did a nice write-up on the canzoomer with a whole bunch of good information. Here's a link for you.

You just seem to be going by the typical "ricer" mindeset of adding up all the CLAIMED HP #'s provided by the manufacturer and expecting to get that output in the end. Stop kidding yourself.

Fanman 03-22-2005 10:33 PM

Your making a critical error in your calculations. Improvements are not cumulative. Even if you saw some dyno posted that said 9 whp for the hi-flow cat, & you another dyno with the Borla exhaust that gave them 3 whp, you put those together & you will not get 12 whp. Probably closer to 10 whp. Doesn't work that way. Like RG said above you will be lucky to grab 10 whp from that setup. Much better off dropping the money on a Canzoomer w/ Random Tech hi-flow cat that they sell as well.

jaehyun127 03-22-2005 11:34 PM

very helpful fanman... as for Aoshi... very helpful again... thank you guys...

redNJ... that's a typical NJ statement. thank you for that.. but not really.

As for the info on HP not being cumulative... i didn't know that at all actually. First time i've heard that. Reading all throughout this forum, everyone seemed to be adding the hp numbers, so... very interesting to hear that.

evilbada1 03-23-2005 12:12 AM

tst tst..just sell ur 8 and get an evo then..

jaehyun127 03-23-2005 12:23 AM

honestly... if the evo came out in 2dr's... i would've instantly bought it. i love that car, but i want to move away from them for now. I'm still young so i want to enjoy it... And the 8 is beautiful, inside and out... so no complaints here. Just wondering what it would be like for some more power...

Fanman 03-23-2005 12:26 AM

It's true. Even if you look at Racing Beat's example above...

Header = 4 hp
Cat Replacement Pipe = 8 hp
Exhaust = 3 hp

That should equal 15 hp, but Racing Beat goes on to say that the most you can expect is 10 hp from header & race exhaust. On the Hondata sight they pointed to this when people were installing the Hondata ECU with air intake & exhaust for the Acura RSX Type S & were disappointed to only see like a 20-25 hp increase, but if you had added all the claimed hp increases it should have been closer to 30-35 hp. Hondata goes on to explain that is not how it works. Performance parts together are not cumulative hp effects.
