Engine Boggles Past 3500 RPM - HELP

rafalk86 · 07-18-2008, 12:17 PM

2005 Subaru STi 43K miles
-Invidia V3
-Megan CB
-TurboSmart BOV
-AP2 StageII
-93 octane
-Not tuned

When Im going in any gear and go past 3500-4000 RPM the car boggles, what i mean by this is that it doesnt make any power. I have a little bit of smoke when I start up the car.

I am taking it to P and L today to see what they say but im really worried.

I dont think its the tune because I uninstalled the ap and it acted the same way.

Any suggestions would be great. Or ideas or anything.

Do you have a boost gauge? If so perhaps it is at WG boost due to knock. Otherwise prolly something with fuel. Even a busted ringland smoking monster will still haul ass.

Hey guys I figured it out by process of elimination, I knew that it had to be something with the af ratio so i snooped around under the hood, turns out that my spt filter fell off and it was sucking in too much air.

You are lucky that it did not such more in than air. Make it a rule of thumb if that something does not feel right pop the hood and give it a once over.
