BFMIC and HKS BOV install problems after install
Hello to all and I hope that this is the right section for this post!
Before starting too much, this car is an SXT swap with what would appear to be MOST of the components required for the swap mechanically. The car does have check engine light ON, with codes P0420, i know it doesnt have a cat tho lol. I used to get code P0440 but somehow that has gone away. At the time of receiving the car it was only running 5lbs of boost with a leak to the boost gauge, the dealer didn't know what he was dealing with, but she looked clean to me! The idle also sits at about 600 rpms after warmed up.
I have come across several issues after installing my BFMIC and HKS style BOV. First I will give you guys a general over view of what I am running on the car. I am attempting to get the car to 17lbs of boost. Even before installing the larger intercooler, and the WGA nut tightened(more or less), the car would only go up to 15lbs of boost. It specifically would stop at 15lbs, if I tightened it too much it would cutout. Loosen it, back to 15lbs. During 4th gear WOT pulls, the car would hesitate before going balls to the walls. I have only ever seen it fully pressurize and hit 17 pounds MAYBE on 2 random pulls.
Forward Motion Wastegate
Stock PCM masculine
04 stage 0 injectors
HKS style BOV with BOP on turbo
Glowshift Boost Gauge
Oil Catch Can ( Sometimes it is on or off I feel like it negatively effects my cars performance, possibly the can is faulty)
Spark Plugs are gapped between .030-.035 (kept going up to .04 if I only ran it at .035)
Compression tested all 4 cylinders at 151
Radiator compression tested 100%
No Tuner or Wideband at this time haters may say this is required but why would the car suddenly just run like garbage?
The install went successful as far as getting the intercooler and pipe on the car. For the first few weeks the car was running ok, not any better than it was before even though I had made the piping route to the intake shorter, and deleted a lot of vacuum lines.
WGA to Turbo
Bottom of Turbo capped off
Line from PPS goes into the T with check valve on the top and the other end. The top of check valve is capped.
The other side of the check valve goes to the TB
There is a T just after the check valve that goes to the BOV
The only lines connected to the solenoids is the red one going to the cold pipe, and the TIP sensor
ALL other solenoids are uncapped and venting to atmosphere
The CAI that had a vacuum line to it is capped
The brake booster is connected to the port on the intake manifold and also the boost gauge. The line that should be on the top of the green nipple for the heater control system is missing and not coming through the firewall near the HVAC I have capped the green nipple off, is this ok?
The 2 lines coming from the hvac seem to be routed correctly going to the radiator and the line behind the turbo.
At the first of the install of the BFMIC the air sensor kept popping out of the grommet, the red vac line would pop off, the cold hard pipe kept coming off the intercooler or the throttle body. I got some silicone self adhering tape to use as a conduit on the steel and the silicone couplers. Got a deep socket to really tighten the heck out of the T clamps and now all the piping stays on securely and is not coming off. But now that I have the entire system sealed, something isnt right.
Now the car is not running very well. It turns on just fine and seems to idle like normal, but the sound almost seems different. There just isnt a good feel about the car now. The vacuum pressure shifting to neutral dips down to -24 hgi like normal, but it seems to hang there for a lot longer than it used to, the car bogs down when trying to let off the gas at 2000 rpms, as if theres TONS of pressure just trying to tell the damn throttle plate to let me in!
Any help would be amazing, at this point i have tried about 12 different times to figure out what is going on and almost to the point of tears in frustration!
2003 SRT4 Swap, awaiting further info!! Cannot yet post, sorry for lack of info, was going to add more but cant post!
