you shouldn't have told him until he ironed out out the wrinkles. lol j/k On a serious note, We tend to play with what we're not supposed to...

RodrigoSoares

heheheheh

Now I know what the wastegate is! thanks . the turbo has it. also as water cooling and bigger fans (you know, the bnr upgrade). and everything is being asembled by a professional in the tuning area. I know that the Esmeril kit goes for 16psi. Maybe I didn't explain myself very well (sorry for that): with proper tuning, with all the gauges, sensors, proper emanage maping, bla bla (I have it all), how much boost can I make with the turbo and how much boost can the engine go for? My real doubt is how much boost can the tiny two rotor handle?
does anyone of the rx8 experts here (and I say this with all the highest respect for you because I think if someone wants to learn about the rx8, this is the place to check out) knows the answer for this question? pressure limit of the wankel? because the guys from bnr told me that the turbo can go for 25 psi, no problem. but the car can only go for 12psi. but how can the esmeril deploy 16psi? if the car can only handle 12psi?

once again, if my english is poor, sorry.

thanks

To answer your question is not possible without writing a book so
here are some dynos to show you what people have done so far . Esmeril is not there because their dyno was in house - not a private members car. The best any member here has done with the BNR so far is around 300whp but people have been having issues with the actuator - it is capable of much more .

RodrigoSoares

thanks

so, the possibilities are huge. to do more boost, more fuel is needed, more cold air, more exhaust capability, well, more everything :P I had a feeling that the wankel had a great potential, well above the 12psi.

hope I can post my dyno tune up in the near future. I'll keep in mind the actuator problem and inform my mechanic. my horsepower goal is 400. maybe this is not the turbo kit for it but I'll give it a try.

right know, with only injen intake and greddy se exhaust (with cat) is delivering 228whp. we made the dyno run to compare with the after turbo dyno run.

thanks again

It was more of a cough *bullshit* cough kinda thing.

If you have 228WHP all motor, then there are some record books you should be in.

RodrigoSoares

Why bullshit? The stock comes with 231hp, right? At least it's whats on the slip. 170kw of power. I'll post the dyno chart for you :P

Your 8 is beautiful, by the way

I'm a big fan of unbridled optimism.
As was P.T. Barnum.

RodrigoSoares

you guys are terrible :P

laythor

they are also the guys who actually wrench and tune FI'd 8's. So.........

Kane

iTrader: (1)

LOL, the issue is that 232 to the crank only equals MAYBE 190-210 at the wheels with tuning to lean it out and put in some timing etc...

So 228 WHP with an intake is suspect at best.... and beats most race teams on power output.

RodrigoSoares

this was a joke no in the bad way

I see what you mean. I know that to make whp you must make more at crank. But that was the dyno result... I'm waiting for my mechanic to send me the graphic to show you.

Mawnee

You are making the all too popular mistake of believing the Manufacturer published engine output is the same as Rear Wheel Horsepower.

Examples:
2000 Trans Am 320HP from the factory? 275 is a decent dyno.
2000 C5 corvette 350hp from the factory? Dyno 302rwhp if you get a beast
2010 ZR1 Corvette 638hp form the factory......Dyno'd 549hp

And so on and so forth. Numbers you read at the dealership are at the flywheel with the engine on a bench and generally optimistic.

I never get tired of the guy with a Trans Am or Camaro Z28 claiming to have 400RWHP with exhaust and K&N. Really buddy? You picked up 125HP with mufflers and an air filter? Typical "racers" BS at the local gas station.....

RodrigoSoares

I see what you mean. Psychological hp. I'm only saying what the mechanic who made the dyno run told me. when I get the graphic, I'll have my doubts dissipated...

And every time you make a change in your set up (ex. intake) you'll need to tune it up. Just throwing the parts to the car is not enough.

Thanks for all the info. I'm just here to learn

How are you achieving this?

RodrigoSoares

loool I know that, but this guy makes tune ups for a living. So I have a little faith on him.

Sorry, achieving what? I'm not mechanic expert (far away) but in my understanding, every time you make a change to a stock engine, particularly if the change is to aim more performance, it needs to be tune up electronically. Or am I wrong? If you give more air to the engine, you'll need to burn more fuel, or compensate the values in the ecu... I think...

I'm here to learn

Mawnee

I think he was asking what you used to tune your car?

RodrigoSoares

Oh... That's being a big problem. :S

I'm trying to use the AP I bought from him, with the AcessTUNER software (I was hoping to use the AP instead of the E-Manage from GReddy) but I have to major problems:

1- The AcessTUNER software Cobb send me, opens with a USDM Base map RX8, and I specifically asked for a EUDM RX8, FI'd.

2- When I try to load a different map, for example the map that MM has on the download library for FI'd RX8, gives a specific error message saying that the base map I tried to load is not compatible with the software....

Any help?

MazdaManiac

iTrader: (3)

Yeah - there is no AccessTUNER RACE software from Cobb for the Euro models.
It only works on USDM M/T AccessPORTs.

Since you only bought the thing in October, why aren't you taking advantage of the Custom Calibration Service that was included in your purchase?

RodrigoSoares

Crap... :S

You're right Jeff (can I call you Jeff?). The thing is I wanted to wait 'till I get the 8 FI'd. And then send you all the info so you could make me a map.

But right now, I'm having a big doubt in my head: my set up, in this moment, is: greddy turbo kit with bnr upgrade, 650cc secondary rc injectors and walbro 255. The doubt is: can I start the engine safely? Let's suppose I have the EUDM FI'd base map installed on the AP (the one you have in your site). Will I be able to start the car with no problem? The injectors and the pump won't be sending to much fuel, once the map is for stock fuel system?

Sorry for all the trouble I'm giving you guys. And thanks again for all the help

(f***! the mechanic broke the fuel pump connection!!!! the one where the fuel line from the sender unit is attached. where the h*** will I be able to get the fuel pump plastic enclosure??????? used, new... whatever! in Portugal only new and for about 400$us :S)

MazdaManiac

iTrader: (3)

Of course!

The service is good for 6 months from the time you purchase the unit.
If you go FI next year or 9 months from now or whatever, you will need to renew.

Yes. The base calibration will work.

Kill two birds with one stone. Get the BHR upgraded fuel pump assembly.

RodrigoSoares

I never used the service due to long delays in getting it FI'd. I know the 6 months have passed but I was hopping you could give me some slack and make me a map... free of charge :p. And then, for future maps I would renew the service, of course.


This will make my life easier :D So the bigger injectors and the more powerful fuel pump won't soak the engine, nor the plugs? That's great.



I already have a walbro. It was because of the assembly of the walbro that he broke the damn thing :p. But thanks for the tip anyway.

One thing I've being noticing is that almost everybody as upgraded the spark plug wires. Will this make a diference? I also have the HKS Twin Power DLI II ignition amplifier.
