guys, a PI just msg me that they will be bringing in a high spec rx8. never heard of it unless they tune already before bringing it in.

Fab 8

Just means a fully loaded one - type E or type S, maybe with some options thrown in. Nothing to do with the engine tune.

watoke

It is 250bhp? 6MT?

Naughty Boy

Is it the mutant blue MS special? Was limited to Japan, but with enough $ & connections...

sgrenesis

have really no idea but will call up the PI tomorrow.

Neon

Herd of Bulls.... :D

Genesis

haha....wot, u think SE's don't have our best interests in mind when selling us cars? :p

sgrenesis

doesnt really matter since i am still waiting for my car. nothing much to do anyway.

sgrenesis

Yup its the 6MT 250HP

Manwe

there is no 250BHP. Mazda have to revise the rated HP down from 250 to 238. That is the high-powered version. All have to do with emission criteria etc.

watoke

Oh, tot they launch it at the Paris MotorShow? 6MT 250BHP, and I think World of Wheels is bringing it in. ANyone can confirm that?

Manwe

the renesis was designed to put up 250bhp. But however, it couldn't produce that amount for a production car. So mazda have to revised the hp downwards. Infact, they did offer some compensation for ppl affected. Anyway, it is a NA car. I think NA car achieving 200+ bhp for a affordable car is quite a feat.

Neon

Manwe, it is only true for Euro/US spec Type S/GrandTouring spec.

Mazda Japan has not bring down the JDM spec of 247HP to 238HP. What u said about emission control is true for US and Europe, not locally in Japan.

For simplicity sake, JDM models are printed as 6MT/250. Dats all....

Someone correct me if i am wrong. Bottomline, MM is bringing in Euro Spec which is 6MT/238 and not JDM 6MT/250.

Guys,

I posted on the power rating before :

JDM Type S is rated at 250PS. I think Mazda Japan attained their design target of 250PS. It's just Mazda NA didn't know the difference between PS and HP and pre-advertised 250HP when 250PS = 247HP (SAE). Read my thread for more...

Actually the car mm brought in is euro specs, which is 231PS and that works out to be 228bhp.

Althought JDM is still using the pre-production specs 250PS, I'd read somewhere that the performance is still not exhibiting anywhere near that. It is probably closer to 230-240bhp in reality.

But whatever the case, US/Euro/JDM that are all known as the high spec(standard power) and the difference in the bhp is due to ECU tuning to control emission. And if you look at the available torque, I don't think the bhp would make a significant diff. cos the RX8 indeed lack torque especially at lower rpm.

Sgrenesis, if you think that buying one with a few more bhp printed is going to give you better performance you would be disappointed. It doesn't work. What you need to do is to get FI to increase the torque at lower rpm. But don't get caught by LTA.

Neon

They are not the same. Engine's name is already different, so how can they be the same?

One is FE32 and the other SE3P. Although i agree that controlling engine emission was the main reason for that labelling. Now try making FE32 the same as SE3P by gettin into our CANII ECU, dat will be a hard nut to crack wouldnt it?

Both Engines are the same = 13B MSP

Agree that torque sux on both but FI is not the way to go IMO. Renesis wasn't built for FI/SC or even NOS... Well dats my take...

Cheers

sgrenesis

My bad!
its 250ps NOT hp

BTW what FI/SC

Fab 8

FI/SC = Forced Induction / Supercharged

I remember reading sometime ago in this forum about how you can't just plug in the JDM ecu into the american versions and release the additional horses. This is something I have always wondered about - why do the Japanese spend so much money making the JDM models different from export models?

Manwe

Neon, actually it is the same engine, tuned differently. The code is just for their own naming convention. Nothing to do with the engine. It is build the same way. Just different supporting electronics.

Manwe

By the way, the engine definitely can take FI. Whether or not the engine can take FI depends on how much boost it can take from the increased pressure. It is a matter of how much boost it can support, and how to channel the exhaust to drive the turbo etc. The layout of renesis is different from the RX7 as they change the position and timing of the ports and that makes it more tricky to do a good FI.

I am not really a racer, and thus I don't think I would actually have FI done. I prefer NA cars as it is more responsive. Lastly...NOS is bad....cars are not meant to run NOS. The sudden and tremendous increase of pressure would shorten the lifespan of the engine. Anyway, NOS is ILLEGAL here. Dun even think abt it

Neon

Dats wad i said both engines are the same = 13B-MSP...

I didnt say they are different engines...??!~!!

Opinions r opinions....Well i can argue that Renesis can take NOS too! Just how much. I can shoot 20HP equivalent of NOS into Renesis and i bet it wouldnt harm it at all. Same for SC, i just put a 20HP SC - No problem. But all these at what costs???????????

My point is Renesis is already running at nearly its peak performance so to get dat little extra performance by FI/SC/NOS is quite a waste of money....

Manwe

Neon,

It is not about the extra hp. It is the torque gain that matters. No one really knows how much boost renesis can take for sure without screwing it up. Of cos there are racers who give incredible boost to the renesis. But you wouldn't expect those cars to survive many years. All we can do is wait for mazda to do their r&d and then see how much improvement FI can give and if it is cost-effective.

Neon

Funny, then in the meantime you are telling people to FI the renesis. Shouldnt we all just wait for Mazda RnD then?

It's not all about Torque. Initial acceleration and pickup may see you through but at the finishing line with a long straight a 500BHP/HP/PS car will eat a 238BHP/HP/PS for breakfast.

I stil dont get ur point in all your threads??

Manwe

I'm not telling ppl to FI. What I am saying is that a slight turbo or supercharger would definitely be more noticeable in terms of performance if you compare jdm/euro/us specs cars even though the listed power is different. No point hunting down the one with the higher bhp as it is not going to significantly affects performance. The point I am making is don't be concerned abt the so called bhp in the different specs as they are still essentially the same. No need to get excited over the so called 'high spec'. Just a publicity gimmick.

Most tracks have minimal long straights anyway. And what sort of kicks would one get using one car with high hp to beat a car with lower hp on straights? The only ppl who do that are drag racers and they are not competing driving skills(requires none) but their skills in mods & launch techniques.
