Pronto video en el dyno maņana 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.

 

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?
