Pronto video en el dyno mañana otra vez a darle en dyno

Looking very close to completion ... when is startup ?

Starup but 1200cc are two big I need 850cc injectors to finish.
El carro.me falla con los injectores 1200cc le quedan grande. Compre 850cc estoy esperando injectores 850cc pars.setiar a 7 libras. Para luego subir a 9 pero hasts ahora todo funciona menos el tacometro.pronto se soluciona ese problema. Video coming soon.

Perron!

Does it run now?

Yes. now we are working on the details. Lowering temperature programming and open all port in the intake for better free flow.

So it has no been confirmed Greddy turbo with the use of Haltech 500 ECU will work on the S2 RX8. Nice!!!!!!!

work perfect haltech ecu on rx8 r3 with greddy turbo kit or another costum turbo kit.

Corrected ....

I should rephrase, does it run with all 6 ports working as they should or are only 4 ports working and you're trying to wire open the 5th and 6th ports?

We leave open the last port in search of a better answer. Looking for a better curve at 7000 rpm.
Attachment 222143

Leaving the aux port open below about 5500 rpm will result in a significant power loss in the lower rpm range ..... Fact .
There are only minor gains to be had in changing the the Aux port opening rpm , a few hundred rpm earlier than stock will give small gains.

BUT : for a stock Greddy turbo the best option is to Leave the Aux port closed completely as the stock turbo will overspool at high rpm if the aux. port is left open .

This turns the engine into a 4 port but means the turbo operates closer to its efficiency range and will allow you to run more boost to get back the power you lose by not opening the ports.

Unmm. Ok my car do 255bhp with 7psi.

Buth on Street make 9psi @8800rpm. Maybe 7 hp more.

Great to hear - excellent result .... any chance of a dyno ?

RX8 R3 with greddy turbo kit haltech ecu:

Hmmm now I am wondering if this Haltech ECU will be a viable option for a series 1.

I know that it's been attempted before without success but from what I've read that was only one attempt.

Work with serie 1 or 2. Only you need the correct mecanic.

With the right person tuning it It would surely work ok . The problem with most stand alones is drivability . Nothing else works quite as well as the stock computer re-flashed by Cobb or M/E .

255 bhp or 255 rwhp?

255bhp would be pretty sad . He meant 255WHP which is in line with what we know the greddy turbo does on the S1 at the boost figure he quoted .

On wheels 255

For now we seek to improve the program,researching, the details and replacement parts to improve. But coming soon 400rwhp with apex seal and new turbo.

I figured as much, but you never know so was just seeking clarification.

OP, is the goal just to turbo the car or to do it in a way that would pass emissions?

Oh, and that rubber oil drain hose will be toast in no time. Mine was toast after a few thousand miles and it was high temp silicone and and wrapped in DEI shielding. Also, you have a vented catch can but with a second hose on it, where do you have that running to?

I'm interested to know how well the car drives for normal everyday use .... Idle , low speed part throttle acceleration , transition into boost etc .

No sugar coating ....................please . Too many bad decisions have been made around here based on someones over enthusiastic evaluation (driven by a desire to stay onside with the supplier ).

Yep, dyno pulls are one thing, cold morning start up and driving in 100+F heat in traffic are another. Thanks for sharing, I am looking forward to the finer details.

Sorry English is not my first language. Rubber is special and is not regular rubber and is protected. The car is running normal with no problems. All suggestions and help on the project is accepted with respect. My mechanic has made rx8 with over 400rwhp , stock engine without problems since 2004. But is it the first rx8 series 2 with small turbo. On the other hand my mechanical are friend of the racing beat engineer and Esmeril racing and he worked together on the research of different rotary engines . So are we in the research and observing the behavior of the rx8 series 2 with the small turbo and haltech ecu. We get valuable information direct from racing beat, the limits of rx8 engine in timing on boost and exhaust temperature limit. We return to the dyno for new program with new information , horsepower will be lost but will be safe , as we continue to investigate .
Racing beat information. Timing no more than 14 in boost and exhaust temperature 12.3 to 12.5 is safe on boost with spark plug in 9 or 10.5.

in Puerto Rico have no problems with Emissions who made the law made the trap

There is nothing better than using the oem ecu and program it to with the turbo kit, but in the series 2 I can not do, so I had to choose between microtech, Haltech or FuelTech. soon video in morning and daly use.

Any advice??

Hi Gamaliel 31 I pick up a red one

Series 2 ECU be damned! It's been holding back the tuning potential of this car since day one...

You can use Mazda Edit on the Series 2 ECU and most recently Versatuner started support for it.

VersaTuner is tuning software for Mazdaspeed, Mazda MPS, CX-7 and RX-8 vehicles. It is a Windows application that allows reflashing/remapping (chip tuning) of Mazda MZR DISI and rotary engine ECUs, data logging, tune editing and diagnostics. No matter what your goals are - increased horsepower, better fuel economy or engine performance analysis, VersaTuner offers a rich set of unique and powerful features with an attractive and easy to use graphical interface. It leverages the power and connectivity of your PC/laptop to provide a tightly integrated, colorful and exciting tuning experience that has been designed for the modern world of social networking and internet technologies. VersaTuner unlocks the hidden potential in the engine of your car.

Supported vehicles:

Mazdaspeed6, Mazda 6 MPS or MazdaSpeed Atenza (all regions)
2007-2013 Mazdaspeed3, Mazda 3 MPS or MazdaSpeed Atenza (all regions)
2007-2013 Mazda CX-7 (all regions, turbocharged gasoline engine version only)
NEW! 2009-2012 Mazda RX-8 (all regions)

you went through all that for a Greddy turbo setup? :squint:

A well set up greddy running 10 psi peak is a beautiful thing . It's not all about peak hp .........

That is really conservative...
What fuel are you using???
With 100RON, you can use at least 3-4 degrees more at 7 psi, with afr under 12.
14 degrees are good for 0.8-0.9 bar (11 - 13 psi).

My friend from racing beat said 14 degress is safe on boost more degress is not safe for the stock rx8 engine. before I talking with y car have 17 degress but he said is 2 much agressive for 91oct.

Felicitaciones, se ve buenisimo.

Que marca de injectores compraste ? , nosotros estemos corriendo los basados en bosch ev14 tamano 1200 sin problemas con el P1000. El truco para nosotros era montar los dead times correcto del injector para el ecu.

Con chispa en rotativo , siempre he sido muy timido. no es como motor piston que los 3 a 5 grados hacen gran diferencia. Especialment con octanaje 91.

clean nice to see the s2 being turbo'd

saludos
 

Utilice 800 en alta ev14 y tengo puesto en baja injectores stock de alta. Hasta ahora 4,000 millas sin problemas. Attachment 220957.

We are waiting acceleration videos :)

Dyno

yes
 

Coming soon with electronic greddy boost controller

Video rx8 with greddy

Sounds good. Pretty rich at idle though. Have to live with all those lights though :(

anything new?

Did that AEM fuel pump you pictured on the first post fit into the s2 fuel pump assembly without issue ? Is it the same pump sold to suit the S1 ?
