First off I want to thank John at Whalen Speed Research and Development for helping me decide where to start and what goals I wanted to reach this season. I dropped my car off to him today (2/2/2016) and will be posting as many updates as possible.

I recently purchased my 2015 PBM Evo X GSR and like I usually tend to do, I wanted more power. This isn't my first Evo, (I've owned a 2004 BBY VIII and a 2005 WW VIII) but this is my first Evo X. When I was driving it home I kept thinking how great it handled, but there seemed to be a lot more the car could do. It was way to quiet, I couldn't wait and within the first week I had my ETS V2 Extreme CBE and test pipe delivered. It really sounds good now, but in the time while waiting I knew I would want more and would also need a tune. I remembered that I had spoken with John about my 2G Eclipse GST project that realistically will end up sitting/parted out/or sold as-is because how much I love driving my new Evo. I reached out to John about the Evo, and we talked about goals and plans for this year. I want to lay out the information and share the story as we go through it and keep the thread posted with updates throughout the upcoming racing season.

Parts List:
AEM 320LPh fuel pump
FIC 1100 cc injectors
ETS V2 Extreme CBE
ETS test pipe
AMS widemouth DP
ETS LICP, UICP (black wrinkle finish), and FMIC 3" core for now
ETS air intake kit
Cobb AP v3
New X line AEM wideband o2
E-85 & 93 octane map/tunes
EBC
CC Twin Disc Clutch
ATP Garrett GTX3076R Bolt on type (twin scroll)
Motul trans fluid
Redline 5w-40 oil for maintenance going forward, may try Rotella T6 later.

That's it for parts for now, as far as I can remember. The engine will remain completely stock, I want to push it as far as I can and as reliably as possible.
With the GTX3076R I want to remain as street friendly as possible while being able to produce some good numbers. We are currently aiming for 500 AWHP (realistic goal, may gain more if there is enough left in the injectors) and 400 Ft-lbs on e85 on this setup. The fuel system is where it got complicated due to a change last minute over a different turbo that fell through. We know that the pump and injectors are going to be a restriction at this point without a surge tank and other upgrades. I'm sure I will be adding those next off season. The stock engine is also a restriction as far as torque is concerned. I will try and keep things updated as soon as I have updates myself. Thanks for reading this, I hope you'll follow along!

 

Here are the results, like I said I'm very pleased and had a great experience and the car is amazing! The ATP GTX3076R is a great turbo and it has more left in it for sure. I'll try and keep this as updated with track results when the season begins in a few months. If you have any questions feel free to ask me!

 

Nice setup. How much boost are you running on E85?

 

Thanks man!
27-28 psi at peak, the cold weather made it spike to 31 psi last night though after the tune was finished.

 

In case anyone wanted to know I'm at 21 psi on the low boost 93 octane tune. I'm primarily going to run e85 thanks to a good selection of e85 stations in my area, 93 map is more for long trips or to switch out e85 for a tank etc.

 

406hp on 93 octane at only 21psi with what appears to be 11.3 AFR on the top end !?

THAT IS CRAZY.

And then add another 100hp or so with E85!?

Your tune and setup made 200lb-ft of torque at 3,200rpm. That is only 200 rpm later than my 20g-TD05 (sts 9 blade) setup.

What are your injector duty cycle maxes on each fuel?

Only 61%-62% max IDC% on 93 so there is room left in that one for sure. Max IDC% on e85 was 92% to keep knock count down and leave a little room for safety reasons on 28 psi for the e85 tune so it overall just changed the car in to a whole new car. The car just wants to keep pulling and the torque curve is so flat it held very well through the new 8K rpm redline. This is all on a stock 4B11T GSR, no cams or spring upgrades the engine was left untouched. I'll just be enjoying the car as is for now and hoping for reliability with maintenance kept up on it for as long as possible.

 

I wouldn't make a habit of revving it out to 8k if you want it to stay reliable on stock valve train / bottom end.

 

No, not in daily driving situations. Maybe during track days but that'll be about it. If it stays healthy this year I'll end up upgrading valve springs, retainers, and GSC S2's over next winter.

 

The reason I asked directly about your IDC% is because you listed FIC 1100's. Which from fuel injector clinic themselves is only good for 411hp (whp):

WHP on E85 at 43.5psi 90%DC Turbo = 410.99

Perhaps your fuel pressure was raised

I'll have to check with him about the fuel psi being raised. AFAIK it's still using the stock 1:1 FPR though.
