Stealth 10 with FPred
This 10 is California and Wife stealth spec. 
2008 Evo 10
Mods:
Stock catback (removed internal flapper)
AMS downpipe
GST testpipe
FPred @ 24psi across
DW 1000cc injectors
Drop-in air filter
GST Boost pill
GST Custom dyno tune (ecuflash)
91 oct
337whp / 279wtq
This was an interesting setup. Super quiet and looks 100% stock under the hood and exhaust wise. Isn't any louder than stock at idle and cruise. The red is obviously being held back with restriction. This Evo made 302 whp with the stock turbo so good gains with the red for the current setup.
I'd fully expect the power to jump another 20+ with a aftermarket catback.
For reference a stock 10 puts down approx 22X whp on our dyno

Haha awesome! Stock engine cover installed still too? Very cool, I love stealth setups. Why, I have no idea, in MN we can do whatever we want. Still, I'm impressed; understated is cool. E85 next?
Also, how hard was it to remove the flapper in the stock exhaust? Have to cut it open and weld it shut?

You do have to cut open the exhaust to remove the flapper.
He has plans for E85 in the future, hence the 1kcc injectors.

This Evo 10 upgraded to a RRE stealth catback.
Should be interesting to see how much power this gains over the stock catback with this turbo.
Stay tuned....

I'm looking to go the same route with my Evo X MR because it's a Daily Driver.Current Setup:
- Cobb AccessPORT
- HKS Panel Filter
- HKS Legamax CBE (sounds stock until WOT, then it sounds like a jet)
- Planning to add an FP Green and would like to see 340-360WHP.
