Were these logs that you put into VDR from the street or from the dyno?

The log from the dyno pull.

Our dyno matches street loads almost exactly. I posted a thread a long time ago with overlays of load,psi,afr, etc that show this.

You can see that thread here: https://www.evolutionm.net/forums/ev...reet-load.html

I use the old 5.71 version of this quit a bit for fun. I pulled my car off AMS dyno and a few hours later did multiple runs on VDR "on the street" and it was within 5hp through the entire HP range on average.... VERY close i was very surprised when i 1st tried it.

I did a little bit of touching up on the tune last night. Yesterday was record breaking temp for the bay area. 95* or so during the day and was still in the 80's even at 11pm.

I have to get the AEM intake box on STAT as at 11pm I was seeing 113* intake temps even driving 80mph. The good news is the CBRD FMIC had no problem taking the 125* manifold temps down to the intake MAF temp shortly after going WOT.

I still can't tune out that damn dip in the boost curve. I really think it's the exhaust flow at this point.

For what its worth, I have an extremely similar dip in torque at the exact same place where it then levels off. I have a stock intake with drop-in, stock dp, and a 3" cbe with test pipe. Looking forward to seeing your solution for this.

hmm. that is wierd... my last turbo car had the same dip after installing a bigger turbo. it had full 3" TBE with test pipe too... i ended up getting a bigger TB (from 54mm stock to 65mm), and 256/264 cams because that's what the shop thought what the bottleneck was.

Got some time to throw it back on the dyno today. Did some tweaks to the tune.

Solid 320whp now. Good 10-12whp/wtq gains throughout the curve.

E85 in about two weeks. I'm going on a road trip this coming weekend and then E85 Army time.

The turbo upgrade totally transformed this car. It just pulls and pull and pulls now where with the stock turbo it would hit decently then just fall off a cliff.

I really don't notice any added lag around town at all.

How is the mpg with the new turbo? Still the same or sucks more gas now?

Did a little more tweaking, here is how the 91 octane tune currently sits:

---------------------------------------------------------------------------------------------------------------------


2010 Lancer Ralliart Sportback

Mods:

CBRD FMIC
CBRD BBX Lite stock appearing turbo
Evo 10 OEM spark plugs (RA uses 7 heat range, Evo 10 uses 8)
Evo 10 Exhaust manifold
Specialty-Z 02-Downpipe combo
Ultimate racing test pipe with mini muffler
Stock catback and mid pipe
Injector Dynamic 1000cc injectors
Evo 10 Intercooler pipes
Evo 9 metal BOV
GM 3-port boost solenoid
AEM intake (3" MAF housing)
Tuned using EcuFlash and Tephra V1 map switch + knock light rom upgrade + PSI-target boost control
91 octane

--------------------------------------------------------------------------------------------------

Data:

Boost: 25psi across, held to 7800 rpm with max of 68% WGDC

MAF Grams/sec: Peak of 387 g/sec = 51 lb/min

- The stock RA turbo peaks about 33 lb/min and the stock Evo 10 turbo around 41 lb/min for reference

MAF Volts: Peak of 4.83v

IDC: Peak of 73.7% at 11.3 AFR



--------------------------------------------------------------------------------------------------

Dyno power results:

Over 120 whp gains at 7400 rpm!

+ 100 whp peak to peak gains

320 whp / 275 wtq

Keep in mind the list of mods, which includes the stock catback still. I also limited the torque for the purpose of preserving the SST transmission for now.



Needless to say, the turbo upgrade has totally transformed the car into a true hot hatch!

For reference, a Evo 10 with comparable mods but full TBE puts down about 340-350whp on our dyno with a BBX Full (non-lite)

--------------------------------------------------------------------------------------------------

Next up is E85! Stay tuned!

I'm green with envy with those results Bryan. Awesome job!!!

I've got a similar list of mods just waiting to go on my car and I'd love to get results like the ones you've achieved in this thread but us Aussies still can't log with mode 23 yet. Grrr.

Keep up the amazing work Bryan

Just curious...Have you thought about putting together a stage package with the BBX and a base tune out for the public? after seeing these numbers and the potential, I'd hit it 3 times haha.

Awesome numbers Bryan! Definitely amazing results. Can't wait to see E85 numbers, aye.

You're limiting torque, but its falling off up top! Moar boost from 5500+ sir! Flat boost curves are so 2009, 2010 is all about the self-induced boost creep

Hello bryan. my name is scott i am new to the tuning/modding world, but i have always had a spark of interest. Now that I have a 2010 ralliart sportback (rotor glow) i am really curious about what options i have or that you would recommend to me. Important things for me are reliable,wont void warrenty,price under $5000 or so. and of course to gain some healthy power!! I have read everything about your project sportback and some i understand and some things i dont. U might not have recommendations yet because your project is still going? i noticed you made a good increase with just the tune. can you explian that and where i might be able to get it. u see i live in smaller town kalispell, mt I dont want to lose to much mpg. I have heard healthy tunes u can gain hp,tq and even better mpg is this correct? this is my daily driver car so i cant be getting under 20 all the time anyway any help you can advise I would greatly appericate your expertise advice and look forward to following your project and hopefully 1 day soon I can take the jump in to tune/mod my first car bye
