For 240hp, You'd really be hoping that spooled up in the early 3000's. Hopefully some tuning can get this happening.

Yes guys, factory JDM twin scrollie with stock JDM factory computer.
Vehicle came in for a power run to see where the car was at.

Boost spiked early and wheened off big time. Although stock power is good, definitely need a tune for Oz conditions and fuel.

Power run on a Honda Civic Type R with Toda Cams and Haltech Ecu. Note that the tune is still incomplete and more gains are to be had as the top end had been tuned too lean by another workshop. Good power nevertheless from a Honda NA K20 engine:

Power run on a P.WRX Subaru GD WRX -- 190ish hp is the stock power for a healthy GD WRX on our Dynapack 5000 AWD Dyno:

With the infamous Subaru OEM canyon in the middle.

Why is that - it's the same in an NA Subaru.

how long does it actully take to bolt up a 4wd car over seting up a rolling dyno at least with the pack style it cant realy fall of the dyno

Good point!

Re: Honda EP3 Civic Type R
1) Bad cam timing set up
2) VTec chg over point was not smooth in the tune -- more ignition timing to counter this.
3) AFR not optimum.

Re: Subaru GD WRX
1) Variable Valve timing.
2) Stock ECU weens boost off quickly. Factory ecu set to a target boost of .98 bar and uses the conditions of cumulative, integra and consolidative controls via the complicated factory ecu settings to bleed boost off via the boost solenoid. They do this in most factory turbo cars in Australia to meet fuel consumption and emmision targets. In this case, the boost is controlled via PID algorithm (Proportional, Integral and Derivative) which is a closed loop control system used by Subaru on their factory ECU. Those familiar with Motec, Vi-pec, Ecuflash and Romraider would have rub shoulders with this scenario.
3) Igntion timing

Lol. No it won't fall off the dyno dude, it is totally safe. A whole list of approved Dynapack operators are listed at [url=http://www.dynapack.com/index.php?option=com_content&view=article&id=51&Itemid=67]Links[/url]

The list includes , Apexera(Apexi), TRD, Trust, Gruppe M etc. All authorised operators who have met Dynapack's criteria, are properly trained by Dynpack before being approved and listed on this site.

Mao, I clarified what I meant. Even my now sold NA Liberty had the god awful canyon in it's graphs. It isn't turbo dependent in my experience - it's a feature of Subaru OEM engines it seems.

I do understand your explanation.

Sorry bos, I didnt go into NA clarications, but the other 2 points of Variable cam timing and Ign Timing applies as your vehicle is NA.

In the case of a turbo car, I think RoughStilin's Vi-pec tuned dyno graph is a good example of how we retune timing to get a smooth torque and power graph.

In you case, the same variables of afr and timing will apply.

Below is Gav's Vi-pec tune:

Agreed ... All turbo Subarus appreciate a tune.

No no, you are mistaken. Sorry I have not logged a lot of NA cars on my Dynapack but I have personally been doing a tune on a B18C converted Civic using the Motec M4. The vehicle is a Honda EG Civic that is used regularly on the track. Customer came in with a bad variable cam change point and I smoothened the power curve with just a bit of timing.

Will post up the power curve on what I have achieved so far, as the job is on-going because I am still waiting for some data logs from his track session to finish the job off.

Won't be long.

Here's the before and after power graphs on the Honda B18C converted civic. It is obviously NA and I got rid of the canyon with a Motec tune.

Before:

After-tune with Motec M4:

Yup saw your graph.

NA or Turbo -- it is all in the tune to smoothen it out.

You power run wrx's with the bonnet open??

1) We are required by law to keep the bonnet opened while on the dyno with at least 2 fire extinguishers on standby within 5 mtrs of the car.

2) Hp and Torque differences are so minute between an open and closed bonnet. The difference in hp between different air filters is more substantial than that.

3) At Evolution R, we do not worship numbers, instead we look at the overall graph, accuracy and driveability.

4) We datalog boost on our power runs which means the bonnet has to be opened.

5) Our Dynapack 5000 is the latest Dynapack in WA calibrated on a Porsche GT3 last year. Although our Dynapack 5000 reads lower than other Dynos, we pride ourselves in giving an accurate and honest hp reading. (Had a R34 GTR 550hp on another popular Dynapack Dyno which read 450ish hp on our dyno recently.)

[QUOTE=RUSSGT;630665]You power run wrx's with the bonnet open??[/QUOTE]

Wasn't interested in all that. More interested in the fact the tmic isn't getting any airflow. That bit about the law is strange though as lots of places tune wrx's with the bonet closed.

Russ, I seriously do wonder how much the turbine will heat up in a power run.

[QUOTE=RUSSGT;630829]Wasn't interested in all that. More interested in the fact the tmic isn't getting any airflow. That bit about the law is strange though as lots of places tune wrx's with the bonet closed.[/QUOTE]

Heaps. How do you tune wrx's? With the bonnet open? Do you put a fan onto the tmic?

There happens to be a 15000cfm fan we are running.

Next time when you are free, do drop by. I will show you exhaust temp with bonnet opened and closed and log it on the dyno for ya.


[QUOTE=RUSSGT;631261]Heaps. How do you tune wrx's? With the bonnet open? Do you put a fan onto the tmic?[/QUOTE]

Sorry to be a pain Mao, but without having the bonnet closed do you see improvements when changing to bigger TMIC's on customers cars?

Hi Russ,

How are ya? Intercoolers do not increase hp, but aid in the cooling of the turbine especially in racing and track conditions.

We have extensively tested this open/close bonnet issue. The drag coefficient and air foil cannot be simulated under stationary dyno conditions. We have seen no difference in power gains on the dyno, especially with our tuning method where we do not tune the vehicle once water temp hits more than 90degC.

That is why we road tune the vehicle even after the tuning is done on the dyno. The dyno is just a tool we use to tune safely after which the fine tuning is done on the road, under real time conditions.

Hi P.WRX,

I have successfully OST tuned an MY10 WRX. Parts involved in the install were: Mac USA boost solenoid, Turbo Front Pipe and Perrin headers. The Perrin headers were a little small, but we made do. The Process West intercooler supplied by the P.WRX member was one of the best I have seen.

I will be putting up pics of the install in this thread shortly.

Below is the initial power run we did (vehicle already had a cat-back exhaust and K+N Typhoon Air Filter kit):
[IMG]http://img818.imageshack.us/img818/9255/dsc01941m.jpg[/IMG]

Below is the highest hp I achieved, however I had to redo ignition timing to suit as the power and torque graphs were still not smooth enough:
[IMG]http://img444.imageshack.us/img444/3083/dsc01940j.jpg[/IMG]

Final Graph-- Torque reached a peak early and there was more power to go but we set the redline on the Dynapack at 6500rpm as the car had achieved a lot of hp already and I was not prepared to push the car further with more timing. Boost hit a peak of 0.95 bar in this tune:

Thanks to Ken for the opportunity to OST tune his car. We now have enough data to properly OST tune the MY09-MY11 Impreza WRX/STi. We will proceed to offer power upgrade packages shortly.

When can I come see you Mao?

This Verso tune that I just got is turd as stated in my PM. Are you able to take it off given that I still have the factory ROM?

Hi Jon,

I will send you a PM this weekend. Head is still spinning with ROM definitions.

Regards.

Why has the peak torque slid to be at almost 5k rpm on the finla graph compared to the 4k rpm of the middle graph?
Is there away of keeping the response and smooth it out at the same time?

In the middle graph, I was trying to get the highest torque and power in but there is so much the stock engine and turbine can produce. If it was a forged motor, adding more ignition advance would have allowed the middel graph to go all the way smoothly.

But for the standard turbine and motor, to smooth out the response further, best is to reduce total power and torque safely and get a smoother response within the capabilities of the engine.

Thanks again Mao for OST my car, I really appreciate it.

The power and torque gains was more than i expected =)

You should create a driveway thread and outline all you've done to the car with photos, etc etc. Looks hot going by your display pic.

Forester is booked in for a power run tomorrow arvo. thanks Mao

^ what time dave? got car booked in at 9 tomorrow picking it up in arvo would be keen for a look see :)

4pmish

Might turn up for this. Be interesting to see the Foz hit max RPM for once ...

I willl be doing the runs and will get the best hp out of the foz.

However, power running it to rpm fuel cut will not happen.

[QUOTE=GTB Liberty;635909]Might turn up for this. Be interesting to see the Foz hit max RPM for once ...[/QUOTE]

Might bump into you guys if you're still around after 5. Will be there to pick something up.
