We finally got some testing done on the new BBK (BB-X) for the Evo 10.

The "test" Evo is a customers car, has "normal" modifications and makes/made normal power for its level of modifications, if not a little less than normal power compared to other 10's we have had through the shop. For this reason I feel this was a good test car for the new BB-X turbo.

2008 Evo 10 GSR

Mods:

CBRD BB-X stock appearing turbo upgrade
CBRD WGA
T1R catback
MilSpec 100 cell hiflow cat
AMS downpipe
AMS FMIC
RRE UICP
AEM intake
DW 1000cc injectors
BlaqOps progressive double pumper system
Boomba Fuel Rail
APS BOV
GST 3 port boost solenoid
E85 fuel (91 tune coming next)

+83 whp peak gains

+100 whp gains up top!

419 whp / 326 wtq

For a Evo, with these mods and a hiflow cat , these are pretty darn good numbers on E85 on our dyno.

This turbo can hold some serious boost. This tune was at 28psi across to 8,000 rpm. This turbo can easily run more boost as the highest WGDC used was 75% at 8,000 rpm. This car hit 100% IDC at 8k with the current injectors.

Hoping to get some more testing on some other Evo 10's here soon to get more data, so far this is looking to be a great stock appearing turbo upgrade!

UPDATE on 91 oct:

367 whp / 303 wtq @ 24.5 psi

Which is 67 whp peak more then it made on the stock turbo on 91 oct.

24.5 psi straight across to 8,000 rpm

Evo 8/9's on our dyno make around 350-370whp with the BBK Full, but with upgraded cams and a test pipe. So these numbers are excellent for a Evo 10 with stock cams and a HFC. This is also a tad "soft" Evo 10 compared to others.

For reference:

Stock 03/04 evo = 190-210whp

Stock 05 evo = 210-215whp

Stock 06 evo = 220-230whp

Stock 08 evo = 215-230whp

Stock 09 Ralliart = 190-199whp

 

Are the stock turbo figures on E85 also?

 

Yes I will edit first post to make more clear.

In that case -nice gains!!

 

Looking forward to seeing the results on 91 oct.

Looks pretty similar setup to my car.

Full spool achieved around 3750 rpm... on stock cams?

Think there would be a benefit to adding Cossie or Kelford cams? Or the stock cams are plenty fine for this car?

Is the MIVEC timing very aggressive or conservative?

 

Looks very promising... I really want to get a BB-X.... I'd really like to see some numbers w/ full bolt-on's on 93.

 

I would have been more impressed if it made 419whp on 93 pump. I was leaning toward a bolt on BB turbo, but the numbers dont look impressive IMO.

 

wholly crap - thats some decent results... finally

so about 750->1000rpm laggier than stock...

 

Wonder if it would gain any response with a P&P on the exhaust mani or something tubular...

Also made the torque flatter with a loss of peak torque...

 

Great results as always!!!

Thanks for posting the results,

Now for some pump gas numbers!

 

That is a serious boost plot. Thanks for sharing Bryan. These results have been long awaited.

 

Good results. I would like to see what this would do with larger injectors.

 

What is the reason for the dip in power during the last 500rpm of the power curve?

 

The cat is definitely not helping the numbers...seems like a very responsive street turbo though...
Good job!!!!
