Finally the wait is over, a dyno sheet is here.



First off my engine mods:

BNR built street ported motor with low compression rotors

BNR Stage 3 non-seq twins

Rotary Extreme V mount IC

Apexi Power FC

HKS twin power

550cc primary injectors with 1300cc secondary injectors

Walbro pump

Dp, resontated mp, N1 single tip

Taylor plug wires, running 4 B10EGV plugs

All pulleys



First off I wasn't wanting to push my car. I wanted 15psi and a reliable engine that would last for a long while. That being said, the boost held constant at about 12.5 (on boost gauge) until close to red line. Up high I had boost creep to 15psi. I was satisfied with the power so we stopped. Steve Kan did an outstanding job. After the tuning session, I took the car out for a spin and I'll I can say is WOW!!! My car drives better now than it ever has. I am very impressed with my twins and Steve's magic touch! On the way home the roads were dry so I could enjoy my new tune. I get full boost on my car at about 3700rpms and it holds constant until just before redline and then it creeps to 15psi just like on the dyno. It pulls like no other!



Thanks Steve and thanks Bryan! Pics below:



Unadjusted: max hp = 384 and max torque @ 303

Adjusted: max hp = 375 and max torque @ 295

The air/fuel was a little off compared to my wideband so we tuned by my wideband and not the dyno o2 meter...

 

any particular reason for goin non sequential... outside of simplicity..

reassuring numbers agentspeed... been contemplating on the stage3s a while now...

what duty cycles were you seein at 15psi...

 

I went non-seq mainly for simplicity. It also looks a lot nicer under the hood now. I honestly can't understand why everybody complains about lag...I hardly notice!

My duty cycles hit 80%. I wanted to keep my fuel system set up simple.

To control boost I'm using a high performance dual stage manual boost controller from XSengineering. Basically a waste of my money because I wanted 12psi on the low setting and then 15psi on the high. With my boost creep, I'm at 15psi as is up high so we didn't mess with the BC much...
