I am eventually going to tune for 9.5 psi. From looking at the numbers Jeff was pulling, the injectors will definately handle the load. Hopefuly I can get 300 at the wheels at 9.5psi and a killer tune.

With the greddy kit, keep in mind that I am getting about 7psi.. the map on the emanage is pre-tuned for 5psi. So there is room for improvement in the base tune. Also, if I work the ignition in advance a little bit that can help too. I really do think with the right tune, this Greddy kit can handle 300rwhp safely.... then again, it's always ALL in the tune.

Do you have a timeline for ^these events... or are you going to get around to it whenever... the masses thirst for info!

Jon,

if you're getting 7psi and the eManage is set for 5, how are you getting 7? Sorry if this sounds totally off. ..

Am I totally wrong by thinking the eManage does not control psi and only controls A/F? What determines the psi you achieve, the wastegate? What do you adjust to get more psi?

Yes, ima turbonewb.

Boost controller my friend It allows you to raise your boost levels even though the wastegate is preset for a certain boost pressure.

BAM! I was spot on!

Torque is a big fat ???????? because their dyno wouldn't read it properly.
It can be calculated base on the HP.

sorry for no torque numbers guys, call Altered Atmosphere and bitch at them for not being able how to get a proper RPM reading from a rotary engine Now your thoughts?
If they didn't get RPM, did they at least get MPH? Because then you can calculate RPM if you use the final drive...

Does it have to do with apex seals vs piston rings?

There are only three ways the RX-8 could do anything like a limp mode:
1) Pull throttle
2) Pull ignition timing
3) Add a LOT of fuel (though, really, that wouldn't do much but make the car run like crap)

After 16 consecutive dyno runs - the last 11 without turning off the ignition at any point - nothing like the above ever happened.
This is what I've been saying all along. Because if they had much more than 170whp stock, they'd be running faster 1/4 mile times.

Great numbers. By looking at your graph your A/F at peak power is perfect. There is no room for correction there. By smoothing the A/F you will smooth out the graph but its not going to change your peak power. For every pound of boost you will gain 10-15 RWHP, so its possilbe to hit 270 RWHP by upping the boost to 9lbs and tuning the A/F. I would not touch the timing unless you have an EGT gauge or you risk blowing the motor.

No way. He's gained around 8whp per PSI so far. 10-15 isn't going to happen.

With a proper tune he will. I tune cars all the time and that is the norm.

FYI -- Eric (@ CitySpeed) is fresh out of Greddy kits. Looks like the positive results from our friend Philodox has created a "run" on them. They're expecting a new shipment in a few weeks or so, but their current ebay auction will be for one from the next shipment.

I tune all the time too. I was just tuning 2 hours ago. And yes, my Mazda MP3 gained over 10whp per PSI.

Do I think he could get more power out of his tune? Sure. 10whp per PSI sounds reasonable. 15whp per PSI? Not on a stock Greddy turbo setup with pump gas.

Looks like Greddy should be giving Philodox a customer referral bonus or credit! :D

You havent been tuning rotarys then. Greddy turbo and pump gas have nothing to do with the HP gained from boost. I will leave it at that.

Any particular reason why other cars that use say 9-10psi sometimes double their HP output? I was reading on how a Scion tC put out almost 300whp on 10psi when these tC's run stock 120-130whp. (granted the tC uses a tried and true age old reliable Camry engine :o)

Is the Renesis topped out or is mainly due to its "newness" and lack of work on them?

Do you think 9-10psi will garner say 300+ whp? (still far less than double)

AGAIN, you can't predict HP by boost. The efficency will be different at another point on the map. And the density ratio will be different. In a turbo you can run into turbine efficency problems also. Where are you on the map now?

Where the hell are you Fred, got a girl over there or something?

You didn't say on pump gas, so I think it could definately be done on racing gas.

I understand that boost does not necessarily equate to HP..

I was trying to ask if you believe if there is a some max HP that the Renesis can provide. It seems easier for others engine to double their HP output with a turbo addon whereas the Renesis looks like its struggling to get more than half. In other words I guess the possible potential of the Renesis..

Now I dont even know if its struggling to meet less than half its normal HP, but it seems that way.

What are 350z owners getting by slapping on similar bolt ons? Other cars? Are they seeing 40-60hp gains, or are they seeing 100+ gains? I guess, again since I'm a turbonewb, what are average gains by bolt on turbos?

350z tt at 12psi = 415whps (From roughly 245 whps).

the engine in the 350z engine seems to favor a twin turbo setup, versus a single from what i've read. hate to go off topic can anyone clarify y?
