sr20det speed limiter - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I had a question about the sr20det speed limiter, or maybe its something else. Anyway, I'm running 12psi or so on a mostly stock SR20(filter,downpipe,exhuast). When I get to about 7k in 3rd, the car just stops accelerating. It doesn't feel like overboost, But I just got the SR, and don't know much about it yet. Does it have a speed limiter?;if it does, what can I do to eliminate it?

I'm at 9psi for now, what is the recommended boost level for mostly stock SRs?(high flow filter,downpipe,straightpipe,duel n1,HKSbov) Maybe I was overboosting...

there is no power way up there, power drops substantially after 6k

also, you won't hit the speed cut until about 5krpm in 4th gear...
