I got my car dynoed today. Using dynapack dyno and using 95RON, my car's hp at flywheel is 216 and torque at flywheel is 208NM. Hmm..overall it is close to what mazda quoted. Maybe if I have used 98RON it would be as what mazda quoted. Quartermile is definitely more than 12s.


At the dyno, I heard a story that an msian auto rx8 only dynoed at 140bhp. But with motec tuning he gained 40 more bhp.

I dinosaured mine too.

That's pretty good. What mods do you have on your 8?

coupe07

dynapack figures are always very impressive that makes one tink the car is powerful.

For the more accurate figures, u shld go ST powered n dyno ur car. The machine there and the figures will be the closest u can get for ur car.

mkl22

yup, kinda agree. Dynopack is always very optimistic.

Motec with NA tuning can get 40hp more?? i hardly believe it...... Got exhaust and air intake change??

coupe07

even with intake n exhaust, 40 is not possible, regardless of which ECU u use....

EBS

For 40bhp gains (non turbo), u need

1. Intake
2. Header
3. Exhaust
4. Cams
5. Flywheel/Clutch system
6. ECU

Maybe can come close...

Cheers

Hmmm......cams?? I think we talking about rotary, not cyclinders....

EBS

Sorry blur blur

My fnd NA piston car has all these to get 40bhp over stock.

Cost.... a lot of $$$$. So for our ride... not easy without turbo.

Sharing the info.

silverwolf

ya no cams here. really no headers either.... not much to do there. OBX? i dont think so...
40 hp is going to be FI
heres your list
intake 4
exhaust 3
midpipe 5
flywheel 7
EMU 15 ish
about 30 or 35 total maybe... if you are lucky... keep in mind that just because an all these numbers are give it doesnt mean they are independent. it may be that between the intake and full ehasut you only get 10 instead of 12.

CoupeM

Well..it is hearsay from the guy who runs the dyno shop. So I cant comment on it. As to whether ST power dyno is more accurate or not..I also dunno. To me, as long as the dyno is setup correctly the difference should be minimal plus I am not a fan of ST Power. Hahaha

Besides, I am more concern about the gains rather than the main figure. At least now I have a base run for comparison when I do my other mods.

rayshaw23

is yours the type s or type e engine?

coupe07

OBX??? those are cheap replicas from the states..... pardon me n my language..

they are really nothing close to the real thing.. the finishing, the workmanship and of cos, the quality.

As for e-manage ultimate... there isnt much gains from there. If there is, i wld have done it in the 1st place. Tuning ur original ECU is the closest u can get to 40 horses, complete with the full exhaust mod. Take note i said closest....

coupe07

bro, clutch n flywheel does not increase horsepower....

sqflyer

Yup, agree with ya. Flywheel and clutch does not increase engine horsepower, it just reduces transmission losses. Maybe that gives some effective 'gain' compared to stock? But then our stock clutch is already pretty decent.

Of coz there are headers (exhaust manifold)... how else is the midpipe connected to the engine's exhaust port? In fact, there are a number of different headers to choose from.

silverwolf

OBX... i know is a rip off.. thats why there was sarcasm but i can see that cuz of the comment about "the states" you must not be from, therefor may not have caught the sarcasm... no there are reposrts of lost hp... so thats a no go.
as far as EMU... emanage is cheap and the worst way to go IMHO.
INTERCEPTOR X... thats what you get. you can get pretty much every hp out of that engine with this thing.... search for it.
i know there is an exhaust manifold but like i said its pointless to upgrade... upgrade to what. nothing better out there. although some may argue that there a few.
in every car there are a few header system. this is because we need to seperate what we do for maximum flow. its a must. but just like the intake on the 8, you can only do so much.. the 8 is sophisticated... its a rotory to begin with.

anyways, my list still stands. closest you will get to 40 hp is that list. and a hell of a tuner.

silverwolf

he may not thinking abotu the hp it "frees up" every says the lightend flywheel helps... just does. and thats what counts a faster rev is always appreciated. especially when you redline at 9K

lennon

Where is this shop located?? JB?? Viswork??

CoupeM

Singapore.

Out of curiousity, how is it determined that ST Power dyno is more accurate?

EBS

Nope clutch/flywheel does not increase horsepower. It reduces loss so its as good as 'more horsepower' when u dyno.. No question abt this, dyno proven on my group of fnd's Cl7R.

We had stock against intake, intake, header, exos, intake header exos clutch, intake exos clutch header hondata etc etc abt 4 diff cars.
With the full complement for CL7R, its 46 bhp over stock! (but quite $$$).

Intake, header exos clutch abt 17bhp.
Intake header exos hondata abt 25 bhp.
Intake header exos clutch cams hondata abt 46 bhp.
Intake header exos hondata cams (diff intake from above) 35bhp

Very interesting fig but not applicable to RX8.

Cheers

theboy

rotary car got header?????

Zero_Rotary

header = exhaust manifold

coupe07

they are using different machines to dyno. ST one has a more accurate figure. As to why.. very technical...
