Car: '06 WRX

Dyno Info: DynoJet
Transmission: PPG 5 Speed Dogbox
Gear: 4th (1:1)
Peak HP at RPM: 578whp
Target Boost: Spiked to 26 psi, then dropping to 23 psi

Finally had the time to throw the car on the dyno. Pretty impressed with the numbers it put down with such low boost. We are having a hard time trying to get the boost to hold steady instead of spiking. Also, it seems the car has a choke some where. We started cranking up the boost and it only gained 8whp. We are thinking its the intercooler/piping. Going to address this problem and hopefully get it back on the dyno this week.

banshee....Do you have a graph in rpms instead of mph and what is the hotside to the turbo, I am assuming a .82 or something similar.....Also what is the size of your intercooler piping and intercooler itself, what brand as well.....


reem.....Look at the manifolds thread done by ASF Machine, I think it is in built motors section and yes they do great especially ASF's Monstrosity....

Yes, hotside is .82. The intercooler is a TurboXS Knockoff. Im thinking the IC piping is 2.25in as it can fit into the stock throttle body which is 2.4in I believe. Sorry about that, I noticed that last night. Here is a graph with RPM.

Your car is making good power but it seems kind of laggy. My 6466 makes full boost by 5000rpm, it makes 20psi at 4500rpm 4th STi transmission.

Also 12.2 AFR is kind of lean for my taste.

Nice ride!

If you notice the graph on the first post, there is another graph where the car made 578whp. We didnt change anything except just letting the car sit over night. That graph is in MPH, but changing the graph to RPM, it picked up about 500rpm in spool. We made about 15 pulls back to back while it was reading 105 degrees in the dyno room!

Nice power but definitely laggy. I'd bet some cooler temps will help with that though.

Could you have a boost leak somewhere?

They definitely help! They raise the CR a bit and are more efficient with their hemi shape!

Makes me think that this shop deals in other cars and doesn't see many subaru's.

The guy who tuned the car is my boss. He has tuned 8 sec DSM's to Twin F2 Procharged big block cars

He definitely knows his stuff.

What headstuds? Also what boost control are you using? I had a similar issue and my boost controller was on the fritz. Switched to a manual and problem solved.

If he doesnt get back to you guys then use OEM headgaskets and arp625 (for anything above 500whp)
