lol

Have fun with that.

 

you think hitting 400 whp is easy in an RX-8?
can't wait to see one of these cars of yours...

 

oh i forgot that the number of post on a forum dictates experience.

it's likely that i will finish my twin {seq} turbo FC before i turbo an rx-8. i'm further long in that project anyways.

hitting 400, 450, even 500 is just a matter of money, and smarts, and "all the tricks to keeping it together"... i'll be happy around the 350-400 level and just keeping a stock 6 speed on hand with some half shafts for, when the time comes, because it's not a matter of if, but when. the most i've tuned was a 13b-re block with a gt40 w/ AI. it's likely north of 450rw.. but the owner didn't dyno the car like i requested before having a widebody kit put on the car with ccws. it's likely that if/when he gets his project moving again i will be able to showcase this in my portfolio.

 

post counts aside, I've put probably a few hundred RX-8's on the dyno over the years so aside from Mazdamaniac, I pretty much doubt anyone else here has spent more time with RX-8's on dyno's then him and I have.
But what do I know...

looking forward to seeing what kind of progress you make with that FC and with your RX-8 rebuilds.

 

 

lastphase,

You have a long way to go. I wish you all the best of luck, and lots of spare cash to rebuild the dozens of engines you are going to blow along the way figuring it out for yourself.

There is a reason MM doesn't have any competition, and it isn't because he tries to eliminate competition. It is simply because, to date, no one else has been stupid enough to make even a tenth of the effort required. The people with the money go with a different option in either engine swap or engine management, and usually have these entities called "sponsors". The people without the money blow one engine and throw in the towel. Might call it quits before they blow their first engine.


No one is saying you can't do it. But when we see someone coming in (again) making the claims and trying to start it up, well...it gets humorous to us.

Will you be another flash in the pan? Or will you actually become his first competitor?

Where your head is at right now, you are squarely in the "puddle of gasoline in a frying pan" column. If you want to move to the other, back off a step or three, and start LEARNING this engine, how fragile it is, what it can take, and what it can't. And go from there.

 

Oh i know how to blow a turbo rotary, the FC i am talking about is my personal "experimental" car. i learned to tune on it, and i've build.. like 7 engines for it?
Yes 7. I hate to admit that, it's almost ashaming. But the truth is, the builds were good, they all lasted at least 9-10k, with one going to 36k. but sometimes you think you tune is good, and step on it in 4th and it's done.. then it's back to the drawing board... that car has suffered every type of failure, coolant seal, coolant jacket, oil starvation(from oil pressure wire short, oil level sensor broken and Major front cover leak), and overboost/ running lean.

For the longest time i ran (in my FC) the stock HT-16 turbo, with 9.4 compression rotors, and 87 OCTANE. it started really low and lacking power because i pulled soo much timing for safty sake, then slowly bumped it up. i know i could have ran 93 and added more timing, and made more power, but that wasnt't the point of the experiment, i wanted to see if it could be done.. safely, and how much power it would suffer from reduced timing... i found peak to be around the same with 11psi as if i had used low comp rotors and 14 psi, but the power under the curve... oh man...

i'll be sure to share all my endevours.

 

It's not a matter of going back to the drawing board in your case. You should learn start again from the beginning (theory and related books) if you keep experiencing that kind of failures.

What you probably don't understand is how different it is to tune a common standalone\old 8bit pcm versus a modern car's one.
You would basically have to learn how the tables interpolate together and apply some sound math and theory to it. 4\5\6d interpolations are a pain to deal with.

 

Does anyone know what's the best place to shop for a 20b engine 3 rotor?

 

Somewhere that isn't in completely unrelated threads....

 

I know i'm verbose

 

It should be noted for lastphaseofthis that a Renesis is not an FC or an FD. The Renesis was never designed for boost. 400rwhp is a 100%+ increase over stock and increasing power by that much makes tuning difficult and breaking a motor very easy.

As it has already been suggested, you need to take a few steps back, learn from other mistakes and success before spitting out claims.

 

Those failures were over a span of about 3 years. I only noted them b/c it wasnt the build of the engine but rather the way it was driven, and maybe even partially risky tunes.

I noticed a thicker down casting under the oil filter, most FC's don't have that, and fails around the 400rwhp level.

An FC motor was made for LESS then the Reni and can make 350-400 pretty reliably. The FD engine or brews as they're called here i come from, have larger ports that support more flow, and there for larger power, but aside of that, all 13b's pushing 400+ hp are going to be subject to new (but same) kinds of stress. You think 450 is easy in an FC? or even an FD. hell the bearings in an renesis are a major upgrade to the Fc's, even the stationary gears are an upgrade.. i've got plenty of time to "troll" others' failures.

i just wanted to know if i'm putting my self in a disadvantage by not having the pro version to tune with. vs the race... which it was the whole point of the post. how has it turned into " lastphaseofthis dosen't know how to turbo an rx8 reliably" thread. I've told myself i won't turbo my current one, i will ONLY turbo my rx8 when i get my hands on a white one... i like white.

 

I don't understand why this is being discussed in the ATTENTION CURRENT MazdaManiac CUSTOM CALIBRATION CUSTOMERS thread.

It's no small wonder why Jeff gets soooo pissed sometimes

Geeessshhh

Start you own thread guys ... take it out to the parking lot or something

 

PRO version allows you to create lock tunes.
PRO version also has access to some tables that are not in the ATR version.
Sorry I do not know what those are.

IF you want to find out why don't you call COBB?

 

You meant PRO. RACE is the individual version.


'Cuz he wants something for nothing.

 

Ooooops
I corrected the post.
Thanks

 

I think something for nothing is quite right. If you want tuning software for the OE ECU there are options:
Cobb Accesstuner Pro
Scanalyser Pro Tuner
Epifansoft Mazdaedit

Hell, you could probably pay Colby at Tactrix.com to port ecuedit to the RX-8.

They all have issues, none are free, and they still only solve half the problem. You still need someone who knows how to tune, and turbo RX-8s are very hard. You can't exactly just tune against your knock tables like other modern turbo cars.

I'll save you some trouble with your business plan: getting tuned by MazdaManiac is your best and cheapest option by far. If $300 a car breaks your budget, you are already fucked six ways.

 

tuning via MM is not an option b/c of the wait. i can't wait between his live sessions for an adjustment/improvement in tune.

I did not ask for anything for free... but the diffrences between race and pro, and how do you obtain the pro version.

I did not ask how to tune a turbo rx-8. i did not ask if turbo'ing was easy, or hard. I have 2 more tunes coming up before i even own the first rx8 i will turbo.

You guys musta missed the part about my 9.4 compression ratio turbo'd FC on 87 octane. 87 octane being the key holy **** factor. how many turbo rx-8s run 87?
Mine will. even if it costs me 5 engines before getting it right... octane and ignition timing go hand in hand, but you guys already know this.

Cobb won't be open again until monday... i'll be calling them then.

Thanks again to those of you with.. mostly positive comments.

 

Mine does and does it well. With no motors killed in the process. Good luck in getting yours there also. That will make 2 that I know of. Your's and mine.

 

I believe the PRO version runs between 3 and 5k depending on what kind of "deal" you can work out with the COBB guys. They work from a dealer network and I don't think they'll just up and sell it to anyone, but I could be wrong.

It opens up a handful of maps not available in the Race version, locks maps, and allows the tuner to access locked maps. I'm sure it has a handful of other options not available in the consumer version but I haven't cataloged anything beyond what I just wrote.

 

Hey Jeff, Somehow one of Y'alls MY BHR Plug wires broke while I was going through your tunes, which was apparently causing the misfires in the stock tune in my thread (https://www.rx8club.com/series-i-trouble-shooting-95/reman-already-dead-w-video-216534/) Im on your 5th tune... Im assuming we are going to need to Start from Scratch because you were getting bad data... Awesome... But hopefully this would make sense as my car was slower than a stock 8... Hopefully the new tune sesh will make my car feel like its supposed to...

Lol...

 

"Somehow" one of our wires broke?
I'm pretty sure you mean somehow you broke one of your plug wires.
We don't ship them broken and, since it was working and now it is broken, it is pretty unlikely that we went sneaking into your garage and broke one.

I'm sure Charles can elaborate on this, but I'm pretty sure every broken wire has been installation error.

Probably. You can renew your MMCCS through the link in my SIG.

 

Sorry, My mistake. completely ignore that last post, I butchered it didnt I lol.

Correction: I didnt intend to blame yall, I will go back and fix what I said. But basically it broke, more than likely my fault somehow despite me being careful. No worries...

I dont need to start from scratch, as im still in MMCCS (thank gosh), I just need to get that dang plug wire in. Ill talk to you more about it during the next tuning session, and when I get my car back, Thanks again Jeff,

Brandon

 

Well, we need to discuss that...
