Boost problems

[Tuna_no_crust]

What happens if my actuator has no vacuum line connected to it?

No problem, be sure to let that jb-weld cure!

That'll work, just make sure to throw a zip tie on it and the other fitting. Don't want your reference line blowing off and loosing controller of boost.

You typically want your boost source to come from a source that is as close to the compressor ie turbo as possible. The general consensus is to keep it close and to keep it short.

My EBC has the reference for its map sensor on the intake, and the solenoid is taken from the Compressor housing. Is this something you'd think would create headaches later? I have the innovate SCG-1 that has a separate map sensor for the gauge.

I have my mbc hooked up at the nipple on the IC piping from the Punishment kit and the WG. If you still need to add in a boost gauge, stay away from the BOV vac line. I have read several places (and it's what I do and have had no issues) is teeing into the vac line that connects the intake manifold to the FPR.

I think it's a matter of the more volume the slower the response of the wastegate. That's why you wouldn't want a boost gauge teed in. Not to mention every connection gives the possibility for a leak which would effect the speed of the wastegate response.

Hey guys I did it and everything is fine the car is boosting 12 psi I thought stock pressure for a small 16g was 14 psi. Also after 5-5500k the cars kinda dies like it stops pulling is that normal

 

[lasershark]

Depends on the actuator they will vary depending on age and condition, I had a s16g on my gsx and it was around 8-10 psi without the mbc.
Can you elaborate more on dies @ 5 - 5.5?

What I mean by dying it feels if like the turbo is not boosting also I notice it varies by gear in first it will be around 3-4K. So it will start boosting and at 4500-5500 it will stay at 10 psi and then after that it goes up to 12

Boost leak test. . Does it cut out really hard or just feel like it's not really making boost?

 

[Tuna_no_crust]

Yeah it it just feels like is not making boost

 

[Dsmkauai]

Do a boost leak test. And check the wastgate to see if it's working correctly. You can use a mighty vac and see what psi it opens at and if it will hold.

 

[Tuna_no_crust]

To best explain it it feels like boost lag

Boost leak test should be the next thing you do if those are your symptoms.

well it had a big boost leak but before I got to fix it the car jump timing
