So I recently installed a CBRD BBX Lite on my 2010 Ralliart Sportback. Thanks again to Chad @ CBRD for the great support and a great turbo.

For the people that don't follow the Ralliart forums, my goal with my Project Ralliart is to keep the car quiet, stealth, great street manners (good spool), and not too modded. You could say the theme is OEM+. I have a 05 Evo to be obnoxious in.

I figured the Evo 10 guys would like this data as much as the Ralliart guys since the platforms share the same motor.

To that point, please pay attention to the mods, or lack of, in the current state of the project.



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!

Nicely Done.

 

Thanks for sharing Bryan.
91 on stock cat to corn juice, looking forward to those numbers. Getting a full TBE to go with that?

 

Nice!

 

So this turbo on a evo 10...think it will crack 400whp on your dyno with corn? I am guessing yes?

 

I would imagine so. The BBX full does 430-440whp on E85.

I don't think I'm going to run it that hard on my RA though.

Thanks for posting some data bryan!

looking forward to your results with some more fuel/boost/mods

cheers

Super cool. Need, want, need a BBX Lite on my car!

 

I have one on my desk staring at me

Nice work there, looks like a great responsive turbo and it holds 25 psi to 8k unlike my GT30. Flow wise that turbo looks perfect for the RA owners and any Evo X owners that desire max spool and response yet want more boost on the top end. The stock turbo is a taper monster past 5500 rpm's and this seems to cure that completely!

 

ready to make a switch??

Actually I'm starting to tear into the car again to reach the ~600-650 crank hp range which I think will be the limits of stock block "reasonable" reliability. Basically I want to get a bit more power on tap for the 2011 One Lap event to defend the mid-priced sedan class title. I'll pm you details on what we might want to do with my GT30 with some upgraded wheels, somewhere in the billet 33R flavor range should work out well.

 

Ironically our tubular manifold kit is on a car in the shop right now with a 33RB 4" inlet tial WG recirc'd and some other bits

ok, ill leave bryans thread alone

wow..this looks sooo badass

 

Finally a stock frame for the x that doesn't have huge lag issues. How much chad?
