So Last night my car just hit the 500mile marker and I finaly decided to get on it :yes:. and it was doing better then I suspected it would untill 7000 RPM ... A sudden loss of power :crybaby 1: that i think was the fuel cut. Is there away to fix this can i buy a piggyback for the 2012 skyative trim or have they made one yet ??????
I don't think it's a good idea to push it past 7k, bye bye bearings... Try intake/exhaust if you're looking for more power.
To answer your question, no one has a tune or piggyback released yet.
That true i guess mazda did shave the internals do you have anny suggestions for parts??.. I know corksport but do they carry skyative stuff or all the sensors the same ?....
Thank you or the fast rply
Well thank you for helping out my noobish self i keep looking till i find some stuff ... I have only had the car for a week and have yet to really look at motor... But thank you sir :yes:
The fuel cutoff is there for a reason. 7000 RPM is the Red Line for this engine, the computer is cutting the fuel because any more rpm will damage the engine (broken rods, wiped out bearings ect...). Why would you want to get it past 7000 RPM if the engine is not designed to take it ? You are trying to fix something that is not broken to begin with, not to mention instant warranty void on the powertrain.
my friend has an rx8 and i was comparing speeds and right when i hit high end i was slowly gainging but then redline came and that for sure slowed me down.
I wasnt sure if there was a safe zone after redline like 7.5 rpm i could set it at so i didnt loose rpm when i shifted .. But i guess mazda has shaved the internals so the car got better mpg im fine with how fast it went i was just wondering if i could add a bit more to the rpm..
Skyactiv motor wasn't meant for racing, mainly fuel economy. The 2.5s fare better as far as power goes, I'm just waiting until they introduce direct injection into the 2.5s and boost up the power and FE. I would have shelled out the money for a 2.0 Skyactiv S touring if such a thing existed.
smashing 7k with only 500 miles on it? since when do rings set in 500 miles? or are they pre-broke in before assembly? because to me this just seems dumb.
check for flaking in the next oil change!
plus another thing, getting a few more hundred RPM past 7k isn't going to do anything but slow you down further, How many engines are even effectively making power past like 6500 rpm? and especially a grocery getting NA?

Besides possible engine damage as others have mentioned already, raising the rev limit isn't going to make it any faster and actually have the opposite effect and you'll go slower despite what you felt racing your buddies Rx8. The Skyactiv motor ( like most passenger car motors) is losing not only torque but also hp by the time you hit fuel cutoff and definitely after fuel cutoff. Max torque is around 4,500 rpm and max hp is around 6,500 rpm. That is the power band where the car will pull the hardest ( in stock form). Both HP and TQ are dropping after 6,500, meaning you want to shift at 6,500. Zinging it out to 7K + rpm especially with a close ratio 6 speed gear box has no advantages on the stock engine.
The Skyactiv 2.0 has some big differences in sensors and design over the older 2.0 which is a standard port injection engine. Mazda went with a different style MAF sensor which is what we are working on engineering right now. We have something we are testing out which is slowing down the release of the part. We want to get it right before we cut it loose on the street.
I have only got on it that one time I have read so many ways people breaking motors but I will keep an eye on that oil change for ya lol.. and like I said I'm a newb when it comes to mazdas I came from the crappy Honda world and I'm trying to figure this out here I had no idea where the max hp range was when I posted this up I thought it was mazdas way of slowing the car down... Thank you for your input guys I'm learning something every day and derrick good luck
Yes I know that but car only is good low end once he gets to 7k it is not pulling that well . Do not get me wrong its a quick car and I would love a roarty swap but there is things I do not like with that. For one a turbo mani is like 4k you can only get it from Freddy that I know of and them apex seals suck ass and the motors do not last that long and I live in Colorado and snow with that low end sucks ass as well . I do love my 3 and I do not need speed that much with the handling it has . Best car I have ever owned and hope I enjoy it for time to come I will keep looking at things this wonderfull motor has to offer I'm suprised this post has come this far thank you guys again for the input it has been a learning experience
Huh? You need to drive your buddies Rx8, because it's quite the opposite. They are gutless down low and need lots of revs to make power and make up for the lack of torque. They keep making power well after 7k rpm. If you floor the gas at 3,000 rpm it falls on it's face and will get passed by a old lady on a walker.
Here's a dyno chart of a stock Rx8. Notice that it keeps making power all the way to 8.5K rpm. At 3,000 rpm it's only putting down about 50 HP to the wheels. The torque curve is pretty flat, but it doesn't make much of it anywhere on the tac so you need to keep the Rx8 engine at full boil and utilize the upper end of the rpm band to really get it to move.
Idk man it felt like he had no high end I feel it low end but when we get high end were not aclerating as fast .. idk I have never driven it but maybe there is something I'm missing
the reason why rotaries die fast is because of their design. I know though that if you add 2 stroke oil to the gas every once in a while your apex seals will love you for it.
that dyno says 178WHP? doesn't mazda claim like 255??
