Anyone? If any please share your experience/issue...

Thanks

morganoh

sorry can advice whats a SC?

lowrider

supercharger

CoupeM

woooo....i am quite interested to know as well. =)

Emperor

See Hotstuff magazine....

What sort of SC? Axial flow, Root or Twin screws?
Anyway, Twin screw is the best choice because we get instant and constant boost. This is what we RX8 owner need since we lag low-mid end torque. Someone in Aus by the name of Hymee are still testing it. His project has taken slightly more then a year now. Hopefully, it could be fully completed by Christmas. Currently 50WHP gain at 10psi

Seriously you guys need to hang out more in the US forum if you are after power upgrades, don't take this too personally..... :-)

Emperor

I second that. The guys in the states are good at it. Till we can read Jap; the main forum is the best info source for real power.

CoupeM

I agree...but so far none of them have done the Knight Sports SC Kit which I am very interested in and would like to hear any reviews. Lolz

lowrider

Aiyah... shy shy with the angmohs lah. Theyr england so powderful how to compete?

lennon

Hahah... they will shut us down with their 'england'...... sked leh...

CruiseGuy

Oh really ??? You gotta be kiddin. Whats up man? Hows it goin baby?
Cool... I like your ride...

Emperor

I thought Knight Sports is a greddy unit

CoupeM

Nope..it is not. At least I dont think so. Knight Sports is using a centrifugal supercharger with a mini intercooler. Tuning is by flashing the original ecu. The bolt on kit is very neat....very compact. Tio bo Ivan?

coupe07

greddy is a TC unit leh......

yeah... coupeM is right.. did his homework oredi...

Zero_Rotary

would be more interested on anyone in singapore, malaysia or any place in our nearby region...in the US their 8s have different ECU settings due to their emission control...even if they might have successfully installed an SC doesnt mean we'll too with our 8s... If anyone in our regions has successfully installed any SC with a reliable mapping without too much hassle like the greddy turbo then i might me interested to install one

yiksing

You literally don't have to worry about this if you go for the Greddy turbo with the Interceptor-X as the management system. It is tuned at a lower octane in the US and the car runs fine and could be further tuned in for more power by advancing the timing to suit your local octane. As for the supercharger Hymee and Richard are both developing their kit and helping each other out, I'm looking forward to this and looks like it won't be long.

Emperor

So actually if an expert tuner can tune the car for higher octanes; way more power. But then again, more problems elsewhere.

tems900

just fly in scott from US for Int.X tuning )) or may be buy Japanese SC kit & wait for them to fly in S'pore for tuning, i think S'pore is consider a mass market for them )))

Emperor

SG mass market? Their one workshop has more business than whole SG combined.

Might as well buy a 350Z and dump a bolt-on FI kit. Easier, cheaper and faster.. And so powerful that you can run a business ripping tires for people.

coupe07

well... the greddy TC kit is a bolt on as well... how come u condemn the greddy kit but say otherwise for the bolt on FI kit for 350Z?

i'm sure both requires tuning..... bottomline is.. THE TUNING.

derekwcw

I don't think Emperor condemn the Greddy Turbokit lah, but its true about putting a FI kit on a 350Z. Its so much simpler and efffective than doing it on a RX8.

The research into rotaries still not too indepth, and this time round the Yankees are for more advance than the Japanese in terms of upping the power in the RX8.

And tuning wise, well the eManage still have its issues, as the main issue is still the stock ECU on the RX8, its so well done by the Japs that after market piggybacks can't really fully interact with the stock to bring out the fullest potential.

As for SC, I spoke to "Hymee" over the phone, currently he's got like 2 or 3 RX8 running the SC they developed, still on testing phase to sort out any bugs. Same issues, setting the right perimeters on the ECU. And unfortunately, currently still for Manual only.

I drive an Auto, for all Auto RX8 owners out there, FI in any form is not possible as yet unless for only certain kit/kits. Which currently to my knowledge, only Blitz SC has one meant for Auto, as for Turbo non out there are meant for Auto as yet. You can put one in, but won't work as well and not advisable too.

And for TC, max boost is about 0.6 to 0.65 for engine safety issue, any higher will require internal modifications as well, which currently not much choices too.

So I feel, better to remain NA as well for the time being till more development can be achieved.

Btw, anyone have a Nitrous system in their 8?


Cheers

OK point by point.

The research into rotaries still not too indepth, and this time round the Yankees are for more advance than the Japanese in terms of upping the power in the RX8.

I dun agree. Just look at tuners like re amemiya, fujita engineering, knight sports. They came out with their FI kits first for the rx8. Not the aussies or the americans.

And tuning wise, well the eManage still have its issues, as the main issue is still the stock ECU on the RX8, its so well done by the Japs that after market piggybacks can't really fully interact with the stock to bring out the fullest potential.

the stock ECU is seriously not that well done. Becos u heard your tuner done the dyno and he commented on it, doesnt mean he is right across the board.

Again, this is wrong info given out by you. Re amemiya developed the TC kit together with GReddy primarily for the 4AT. SC wise, yes only blitz. Please do more research before you give any wrong info.....

And for TC, max boost is about 0.6 to 0.65 for engine safety issue, any higher will require internal modifications as well, which currently not much choices too.

Again wrong info. The recomended boost is only 0.4 bar. Anything higher than that, get ready a new engine in 2 yrs. 0.6 or 0.65 bar is wrong info again. Read up pls. Dun hear say.



Seriously i do not know where u get all ur information from. Most of them are mis-informed.....

Let us just put it as he want his car stock as it is
As for the info he listed, I too would need to find an excuse ! And tat my fren is a very good excuse !

As for whether its yakee technology or japanese technology better ! Lets juz say that Mazda is the only one venturing into rotatries, so need we say more ! Not forgetting its the rotary that won the Le man 24 hr during its 1st n oni participation!

IF anyone wants to tune their 13B, make sure u get the right ppl to do it ! Or speak to ppl who has already done it ! If some1 who has had nothing done to their ride and gives u advice, its best kept as advice becoz there aren't grounds to it.

Most of the time its oni the owner who can give u the best bearing as to whether certain things work or not !

Be it TC, SC or NA, there r a lot of tuners out there, stay on track wif those wif history n u won't go wrong !

Tuning a "bolt on" is not juz buying parts and boltin them on and u r ready to c gains.
All tuners know tat there is such a thing call " Car specific", though all Rx8 look genetically the same, one ecu tuned for an 8 will not necessarily mean tat it will work the same way wif another ( c F1 and u will understand why 2 cars ).

There will be many in the forum whom will provide u takes on how 2 tis n tat, all else stil depends wat u wan, coz ultimately u r payin for it urself, nobody gonna refund u if it doesn'y work even though the advice came frm them, they are not obliged to do so rite !!

Enjoy the modding process, its tis thrill tat gets us going though !!!

Hwah.. cool down bro. I drive a rotary too but sometimes we must face the facts. Afterall its really is a different engine.

My point is the any bolt on kit is really easier to install on piston engines and the VQ35DE V6 of the 350Z is reliable for the extra power. And see the V6 part of it, torque all the way.

And we all know Mazda is very selfish by making sure its hard to modify the stock ECU (Good reason considering the 13B is so delicate and mods will increase their liabiltiy for warranties)

The rotary is still in kindergarten while the piston is triple Phd. The first rotary car is the 1967 cosmo and piston cars are already around since pre-1900.

Considering 99% or more of cars are piston; add its long history. Way more research and modification has been done on pistons than on rotaries.

And i am sure many people have seen even how problems can still occur in F1 cars; how can any single tuner ensure better reliabiltiy with their 1% (of F1) R&D budget. Problems are part of modifications. If it was meant to be powerful and reliable from the start; it would already be in the engine straight from the factory.

But on the other hand, mazda did a great job wringing so much power in such a short time from the first rotary. Way less time than comaprable pistons.

A boost of 0.4 is really low. Pistons can handle way more boost than that. Its just a design limitation of the rotary.

Maybe just get a 20B. Just like upping a displacement on a piston.
