Barnie brought his RSX back today for a tune on nitrous. We had tuned the car a while back for his cam setup, but this time he had added the 100 Shot.

Here is Barnie's tuning thread from the last time he was in.

Bottle pressure was a little lower than optimal, at 880-900 PSI. We usually like to see around 1000-1100 PSI.

Here is the setup:

RSX-S - k20a2
Toruku street cams (stock valve springs)
RBC Intake Manifold
Injen CAI
DC Race Header (designed for mid-range)
3" exhaust > 2.25 or 2.5" exhaust towards the end
Tuned on KPro

Zex Nitrous Kit (100 Shot, 880-900 PSI pressure)

Here is the chart.



The reason for a power drop in the all motor tune from last time is because of the flimsy rubber coupler that comes with the nitrous kit and connects between the throttle body and intake collapsed, and thus restricting air. The way the CAI angles down forces it to collapse unfortunately.

 

sweet setup, I bet it hauls on the spray. anytimes with the new tune?

 

None. It would be easy to see 300whp with bottle pressure at 1050.

The way AEM V2 CAI connects to the throttle body would not allow the flimsy rubber coupler that comes with the nitrous kit to collapse... That alone is 10whp.

 

Do a dirrect port set up and tune it on vp116, you will see more then 350hp.

 

I bet thats alot of fun to drive nice simple set up.

 

It's something fun and cheap till he builds the motor and goes f/i anyways.

 

direct 125....

Heat the bottle up and it will hit 300hp all day...A local around my area i think made like 350hp on a 100shot dry on same setup...
