do you think that is?


looking at the graph posted by easy tuning, why does the tq/hp curves intersect at 575x? thought it should be 5252

anyways dynos are just a #.

btw its a modified td06 18g, so I wonder what it really is. Hell it could be close to what BNR does.

well the supercharger and turbo are different. I could be wrong but the pettit supercharger runs out of gas at 13,000 rpms?? I thought the guy from Pettit told me it gets close to that at about 8000 rpm(engine speed). So his supercharger is maxed. With turbo you can just dial up boost and fuel until it pops, or until the turbo cant spin any faster.

I honestly believe with good tuning and adequate fuel, the 4 port can max out at about 360 whp. I think so. but im no turbo guru.

 

 

Boost is Boost. The motor dosen't care how it get it's air.
CFM is a whole other thing. This was covered somewhere else on the Forum.

Um no... It will only be capable of 299 hp.

 

The 1.7 liter Pettit blower has a maximum sustained rpm of 13,000(it will tun this speed all day long); max recommended burst speed is 16,000.

The standard Pettit 8 PSI pulley combination is a 3.5 inch S/C pulley with a 4 inch crank pulley.
4 divided by 3.5 = 1.1428571428571428571428571428571
1.1428571428571428571428571428571 times 10,000 rpm.

10,000 engine rpm = 11428.5 blower rpm

I have a 5 inch crank pulley and hit 12 to 14 PSI with ease.
5 divided by 3.5 = 1.4285714285714285714285714285714
1.4285714285714285714285714285714 times 10,000 rpm

10,000 engine rpm = 14285.7 blower rpm
I also hit 8 - 9 PSI at 2500 rpm.

 

if this guy hit 288, i dont see why he cant hit 360 on a dyno with more boost and fuel with the right turbo.

and yes i was getting at CFM. You can always find a turbo that can flow more air than a supercharger.
But that pulley is the 8psi pulley. which means Phil has room to go. i would like to see what 16 psi on a good flowing turbo would do for the 4port


no one thought the 6port could hit 500.(some of you still dont think so) and chris from esmeril did it. With the right tools it can be done. I never said it could be done efficiently and reliably, but it can be done. some of you guys with 4 ports should try a different setup. That weak *** stock greddy turbo wont get you anywhere

 

5spd manual tranny.......


Hello Justin,

thanks for your inquiry.
We are using the stock 5speed manual transmission.
Unfortunately we never saw an automatic in Greece....

Regards and Merry Christmas,

George Vangelis

This is an enquiry e-mail via http://www.easytuning.gr from:
Justin Thomas <justinsrx8@tx.rr.com>

I was looking at your RX8 projects and was wondering about the 4port
transmission you are using? Do you use the stock manual 5spd or the stock
auto 4spd?
Thanks!
Justin

 

From a PDF on their site about it:

For last, we kept a very important item, SnowPerformance's Stage II Water/Methanol injection system. This system will
be used primry for safety reasons, and we might use some Water/Alcohol mix in the future to increase power output
safely even further.

 

Wow... my sarchasm was lost on you... Oh Well. Merry Christmas anyway.

 

Phil might actually have reached 270 to 280whp had we done a pull in 4th gear. Since we had gotten a great result with a 3rd gear pull it was decided not to push the engine.

With a few modifications and a 4th gear pull I'm sure Phil's car will continue to show that 4 port autos are capable of some power!

 

I talked to Phil recently and for the next SoCal Dyno Day he's going for MAX POWAH!!!

BHR team better be on stand by because the old man said, "300 whp or BUST!"
Make sure you guys bring your tools...

 

tell him to do like the cobra guys and use compound boost!!

 

yeah apparently it went way over my head.

 

Got this message from them..............

Hello,

thanks for your message.
I am confident that a 4 port can get these numbers.
We already have one that should be around 340!
I should post a video in a week or two.
Both 4-ports are using the greddy kit. The one with the 340 has a custom intercooler and a changed compressor wheel.
One other option (we should have results in a month or so) is with the GT3071R.
Two cars that we have already tuned (6-ports) are making over 400HP.
After the Holidays, I will post videos of them as well.
Please note that for safety reasons we are running a water injection system on all of them. Gasoline here in Greece is not of very good quality....

Best wishes and Merry Christmas!

 

Then
multiply that number by 0.85 to get whp. Around 249 whp for those who are counting :/

 

I love unqualified, uninformed statements.

The AccessPORT works on JDM cars.
I've been doing JDM tunes since the end of last year.

I am also EasyTune's only competitor in the Mediterranean. Or, perhaps, I should say he is mine since I've outpaced him by more than 20 to 1 in Europe.
They were sent a C&D letter last year for using the "Custom Calibration Service" name (which is TM MazdaManiac LLC), but they continue to use it. How original. When I get back to Greece next Fall, I'll have to pay them a visit.
His other FI competitor in Greece (GearTech) has MazdaManiac tuning.

I'm certain I have more than one 4-port, 5-speed FI car doing over 300 HP in Europe. There is no reason the 4-port can't do as much power FI as the 6-port since the exhaust ports are the same.

No. Its a DynaPack dyno and it is wheel HP.

 

hey MM.. i know this is slightly off the topic, but have you ever thought of manufacturing an ENTIRE turbo kit for the rx8. You seem to have all of the knowledge. I would invest. Im nowhere near as smart or talented in this arena, but I think you can could make a big difference in the rx8 turbo market, even for the 2009+ series II. You should think about it. btw I know you have the upgrade kit, But i would like to see an entire kit designed by you.

 

well I will admit im not informed very much about mass airflow. I know a little bit in general, but not specifically on a certain vehicle

 

yeah I understand. Well im buying another vehicle in about a month. My rx-8 will be up for research and development. I'm not afraid to blow an engine. If there is anything I can help with just let me know.

btw.. top mount would be good if ya'll did do a kit. Maybe you can throw that airpump out of the engine bay?

 

The air pump gets thrown out no matter what turbo you put in there.
It doesn't make power, so it goes away!

 

Good point - although it would have to be at higher boost . I would imagine the aux. ports do a little to ease the "resistance to flow ".

 

So what? Who cares about boost? Boost is a symptom. Flow is all we care about and the same flow equals (more or less) the same amount of power.

You could rune 75 PSI of boost. It wouldn't matter, as long as the mass flow stays below 450 g/sec or so (where the motors start to break).
That would be a pretty sucky intake manifold design, though!

 

sure - but given the choice I would prefer to get the hp at a lower boost as that implies everything is not having to work so hard to get there .
IE less backpressure/stress on the engine before the turbo + less rpm/stress on the turbo

 

So, I take it you still don't know how to read the compressor flow diagram for a turbo?

 

stop being pedantic - you know what I'm getting at ...
