Hi Guys !

I pick up my car from Mazfix on friday the 25th (this month)
Will be flying up to QLD from Sydney to pick it up.
Its going to be the quickest/fastest 8 in OZ....

I just wanted to kick off this thread as I have been looking for a good system to purchase for the past 3 years...
This is the Go !!!

There is another thread in the australian forum...
I just wanted to share my excitment !

let us know how it goes....pics please

Did you do the upgrade> clutch, radiator, flywheel. How much $


Prepare to tame that beast!

sstricker

how much is this kit?

dbrx8

10k Australian for Stage one. See below my first excited post..
My car has been away for over a week (at a retreat for RX8's in QLD)still with a week or more to go.
It will be coming back to me with a minimum of 200 kw at the rear wheels.
I have driven a version of what I am getting (but not as good ) and thought to myself,..."thank God, I'm wearing 2 pairs of undies!" When I get my car back I will have to wear 3-4 pairs.... because what I drove was bloody fantastic.... I mean it !!! I would compare it to the feeling I got when I was a passenger in a RX7 SP model as it was spinning from 1st into 2nd and 3rd.......

My waiting and hunting is finally over....... MAZFIX are the go !!!!!!!!!

Archie, brock and the gang are gentlemen.
I read somewhere that Mazfix charge like a wounded bull..... Not,..... so I say !!

You pay for what you get!!!
And this is what I'm getting....................
Here we go: Mazfix Turbo stage one , , new heavy duty clutch, new radiator, huge intercooler,(cause I have a Mazda speed nose and have the room) 2 x huge oil coolers, blow off value plumbed back into itself (so no blowoff noise), light weight flywheel and counter weight, a mazfix boost switch located in the centre console for 5 or 10pounds boost, a custom made free flowing catback,....hiflow airbox, turbo timer and wait for it ,............Mazfix are going to do the injectors on the thing.... going for a stage 2 ......as well.


Do I sound excited?

dtorre

congrats...sounds good...though I would keep the bov sound ....one of the sexiest car sounds out there....how many stages are there 3?

Red Devil

Sounds great...what engine management are they using?

Philip_SA

I would guess they use microtech LT10 or LTX12 ?
Am I right ?

Are there any changes to the apex seals, someone here did a turbo job, worked well but bent the apex seals, no break or damage but bent !

Well done anyway, I also think Mazfix are good although I am from SA, just what I see on the web.

Kel Rx8

sounds like a fancy greddy
what actual dyno's are you promised ?

Grizzly8

heres their site

details. www.mazfix.com.

If I wanted a fancy Greddy,.... I know I could get one from "Cia" is oz... I think he's done some mods to his.. This is much more than that..... Arhie from Mazfix knows his stuff and genuinely is a good bloke !
This is not a backyard job!

I will definately keep you guys posted with anything I can get my hands on.

beers !

Take a look at the dyno especially at 7500 RPM:



Another turbo kit that creates a 100% increase in power from only about 7 lbs of boost (i.e. 50% more air max).

The stock RX-8s in Australia must not come with an gas pedal... Either that or grandma was in the car for the stock run.

This ones a little tough to swallow.

298 hp on a dyno dynamics is really good..... Dyno dynamics dyno's are really tight... stock rx8's do 160hp to the wheels on a dyno dynamics..

dbrx8

Why is this hard to swallow??
When I get a dyno sheet on my 8,.. I'm pretty sure it will look better again...

Whats the problem??
Do you guys think the dyno has been "fixed" to make it look better than it is???

You guys are so negative...

MrWigggles

It is impossible to get a 100% increase in power from only a 50% increase in air. To get 100% more power you need at least 100% more air. There is no way around this. (unless of coarse the stock run was not done correctly.)

It is not a purposely negative evaluation; it is a critical evaluation. There is a difference.

-Mr. Wigggles

Red Devil

Not that this would lead to a 100% increase in power, but if the car was completely stock and then received a full exhaust and the intake side and tune was optimized, it should have dynoed higher NA. Point being, I think a lot of tuners are getting more power than we'd normally expect because we are not getting the Renesis completely optimal to start with. Within this optimization, maybe there is another XXbhp/whp to be gained that will later benefit forced induction.

Either way, increasing power 100% without seeing at least 15psi is hard to swallow.

GrRx8MaZdA

Any news-pics on the car?Or either the mazfix email??That's 300whp or crank??

I don't know what to do..I tried greddy and now i am again na and i don't know what to do..Have a rotormaster kit,have a mazfix turbo or make a lot of custom job to fit an fd motor in with 400whp and i am done???
Here with arround 300whp you won't find a lot of cars to make your day difficult...

barcode625

actually, the way i see it it is completley posible. because, as the N/A rotor is going by the port to start sucking in air, there is a spot where it cant suck any more but the port is still open makeing it not so efficient, so when you boost it and you get to that void spot on the intake it is still pushing air into it, that is the whole reason boosting rotarys is so effective.

dbrx8

The bitz used on my car and on other Mazfix Rx8's are not off the shelf. They have been modified to "Mazfix Spec" - customised...Not all turbos are the same size...

Its not all about boost...

its about airflow...

The design is to get the right amount of air needed for the power required.

Didn't Mazsport Scott have similar results with his turbo setup?

MrWigggles

Yes, he did but to my knowledge he didn't show a curve for stock performance. He only showed boosted curves including the following for 5 PSI:


Now 300 HP for 5PSI still sounds a little iffy, but we don't know what the stock performance was so it is possible that his dyno is simply running high. On his dyno, IF stock was 200 HP then his 300 Hp number is possible (i.e. 50% increase in power from about 33% more air and better tuning). Now IF the stock car was only 150 HP on his dyno, that would mean the ~33% more air and better tunning generated 100% increase in power. Well, the better tuning couldn't make up that much of difference and the numbers would then be in question.

Since all dynos are giving significantly different results for the RX-8 it becomes more important what percent gain a modification creates and the "actual HP" gains are less important.

I'm not sure why people are so fascinated HP numbers anyway. When it is all said and done, as an RX-8 owner, the goal isn't turn rollers on a dyno. The goal is to accelerate faster. It all comes down the acceleration i.e. g-forces and the percent gain in g-forces equates to percent gains in torque and thus percent gains in HP. Measuring g-forces is what it is all about.*

Most car mags don't put cars on a dyno, they measure 0-60 and other times instead. In a comparison, Car A could be rated at twice the HP as Car B, but that doesn't matter. If Car B is faster in most of the tests, then it is going to get the recommendation.

My skepticism is design to prevent unrealistic expectations, If you look at the Mazfix plots you might think: "Hey, with their kit I will have twice as much power from only 7PSI! My acceleration is going to be twice as much."

-Mr. Wigggles

*I have used a G-timer by Passport and have gotten very good results that I compared to an inertial grade accelerometer. I don't have much experience with the G-tech Pro but I think its equations are messed up not its actual acceleration measurements. Both products can help a tuner very much. If you are getting .4 g's of acceleration before a modification and .6 g's after a modification, then that mod gave you 50% more torque and thus 50% more power (at that particular RPM).
