I'll get some charts up- but one of our RB-X test cars did as follows:

2006 EVO IX

Mods:

Stock Cams, CBRD FMIC, Injen Intake, CBRD LICP (comes with kit), CBRD UICP with stock battery, PTE1000cc w/255lph, High Flow Cat, Catback

26 psi netted 401whp/332wtq- on the 7163- in 90 degree heat and high humidity- the same car was around 329whp at 25.5 psi on the stock turbo-

changes were RBX kit only (manifold/turbo/downpipe)- peak torque in 3rd gear is right at 4000rpm- so about 685rpm slower than the stock turbo- however the transient response is very impressive-

Ill get some plots up! Cant wait to test on a built motor or some other fuel-

Just adding cams to the stock short block would be interesting.

 

Id like to:

add S2's with springs

remove the cat- retune lol

probably 30whp in that-

The idea would be for the actuator to be in the pull position to close so if something goes south, theoretically, it would relax and the default position would be open. Would make sense to do it this way. But unlike the IWG flapper, this flapper valve is anchored at two points so if there is any movement in the alloy (which is a distinct possibility with alloys as heat expansion and distortion is much greater then ductile iron) it can get stuck in a certain position as alignment becomes lost on thin walled castings.

 

Uh-Oh, If the design is cooked up by the Germans (Kirchheimbolanden or wherever) it will probably fail closed. Just like their friggin cooling system thermostats!

 

Which fuel was used in this test?

 

Pretty sure 93 octane, Dave.
I think your Mustang Ecoboost EFR7163 was Single Scroll T3 frame?
Seems that they both are pulling the same #s on essentially same fuel- you mixed to get 94 octane.

 

Our testing (almost 90% of the time on everything) was on 93 octane!

The Mustang EcoBoost had a twin scroll 7163. IIRC boost was 25 tapering to 24psi, so yes the numbers are very similar.

 

do you have any charts for e85 testing on the 7163 in an X?

 

I have a car that was on :

Stock airbox, stock piping, stock cams, stock intercooler, stock catback- with RBX on 93- and also E85

made 440whp on E85 with none of that other stuff touched-

Wha?

I picked up 80WHP at 12psi with dumping the stock catback (with cat) and adding cams and a tubular manifold.

430 on those ****ty stock parts seems damn near impossible.

 

Hi Chad,

Just as a comparo, what would a BB Red or BBK-B do around similar boost pressures on your dyno on the same fuel. Just curious.

 

it will work fine, same as small A/R 0.48. restrictive.

 

i hope so.
