Did he break a 4-speed tranny or the six speed automatic? Seems that the 4AT tranny has been one with the least amount of problems with the tranny itself. (knock on wood).
|
out of all the RX-8 transmissions, I mean. I haven't heard of any tranny specific problems with either of the automatics.

I know 09Factor has been running a turbo on his 4AT for quite awhile. Phil has been running a SC on his for quite awhile.
|
I know at one point I mentioned that he cracked the flex plate, (the auto equiv to the flywheel). but other than that, IDK. That was over a year ago.
I know Phil has been harder on his trans than mine. Just because his is driven more. MM travels and has had ample time to blow up an auto between Phil and myself, but for some reason hasn't. It could just be the magic he brings with him. |

i have a 6port automatic rx8.. these are my recommendations when turbocharging (this is what I will do)
Cobbs AP-I will change my rev limit to 8700 rpm, therefore i will need transmission coolers. I have dynoed my automatic bone stock rx8. at 7500 rpm it makes 158 whp. Thats real real close to what the manual does at 7500. Generally the Renesis makes more and more power until about 8500-8700 rpm. So theoretically I will be real close to the peak hp of the manual rx-8 IF MY TRANSMISSION CAN HANDLE IT, when I switch my rev limit. I will be installing a T3/T4 turbo. I've never heard of or seen an rx-8 with a T3/T4 turbo. I've seen plain T4's (PTP turbo kit). But the T3/T4 has a faster spool up time, helping the car's 0-60 ALOT, being that the auto can only launch at about 2500 rpm. I just hope and pray that the transmission can handle the power. what are ya'lls thoughts about this? |

Freaklink! I see you made it to the forum.
I emailed you a while back asking about your manifold choice. How is your turbo project going? |
The four speed a/t tranny is stronger than you would think - mine has be subject to 9000 rpm and constant shifting at 8000+ rpm. In conjunction with the AP it is still working very well.

Hey Phil, Do you think maybe Supercharger are maybe less harm to the tranny? because you are having supercharger or you think they both are the same?
Thanks |

American-spec cars don't have a speed limiter.
At least the '04s don't. |

I'm going to use PTP's turbo mainfold. Thats who's hooking up my turbo from Austin, TX. Im also getting the Pettit Racing intake mainfold. They said they would sell me one for $400 |

My 06 auto also shuts off at the same time...:icon_no2:
|
The 04 doesn't have a speed limiter. Or should I say mine goes past 125 mph.

You think Rotorsport will do fine? I know install a turbo on MT rx8 is easy, But on AT rx8 lots computer tuning require.

I can't speek for every a/t but mine never had a speed limiter as I had mine before the s/c to 135 +/- speedometer correction. You would have to ask MM if it turns off the speedlimiter, if yours has one. It does turn off the forced shift points of an a/t and lets you go to your new redline (& beyond) so use caution when/if you pruchase an AP. You can of course blow the whole mess if you go beyond a certain point (?). I just set my personal limit at 9000 and everything has held together. Since the addition of the AP the whole combo runs smoother.

I don't think the AP increases redline on all tunes. You can ask Jeff to increase it but ask yourself if you really need / want that...
