Boosted
Well drove it home tonight, and all I can say is wow the car is fast now. So now some questions.
When cruising down the freeway it is in vacuum at about 10hgs and the wideband is reading 14.8-15.1 (at 75 MPH). Is this a safe operating range? I know I need to adjust the wastegate it is popping at 6.5-7 pounds, and the wideband is reading 10.0 (way rich). But I will adjust the FMU after I get the wastegate set to 8-9 psi. I also now have vibration under my seat. Personally I am thinking it is the open header resonating against the bottom of the car. It goes in Monday for cat, and magnaflow race muffler. But no pinging, no blow by in the catch can, never over heated once, and for a 20 mile trip it did quite well :D Thanks MT for all the support in this build :D |
Awesome! I'll have mine out soon, we should hit up some of the better roads one weekend.
Cruise AFR sounds good actually. |
Congratulations!
Your vibration sounds like a problem I had with my BEGi downipe. Mine was put together slightly off kilter and it rattled against the tunnel (heated it up pretty good too.) Eventually I'll reweld it to adjust but in the meantime I wrapped the spot in question with 4-5 layers of header wrap. No more noise. Hope this helps. |

Congrats! I bet its nice having it boosted. I want this feeling :cry:
|
Congrats on getting it done. Well, not done...done. They are never truly done.

trust your ears, not a computer on this one.
det cans are cheaper anyways. |
What injectors and fuel pump are you running?
|
Make your own electronic det can!
http://rsk.imageg.net/graphics/produ...169791w345.jpg $7.97 at radio shack. Sucks ass as a personal audio amplifier but works great as a det can. Take the mic out and extend the leads with shielded cable. Glue the mic to a washer and bolt it to the motor. All the advantages of a det can without the garden hose running to the engine bay. |
Anyone ever tried that?

at work we have what is called a multi channel elctronic ear. It is basically an 8 channel microphone set up where you put little mics in the engine compartment. They are great for detecting rod knock, injector clatter, lifter clatter, and knock. I shall see if the shop will let me borrow it for a weekend :D

suddenly my det cans get all the love.

If nothing else, I'll need to make sure I'm not detonating on 91 when my car gets out here, so I'm going to try the radioshack route. We can use it to help tune yours if your work won't let you borrow the big ear.

Congrats man!
I hope to join the club soon, but as I near the end of this build I realize the victory won't be in the finish, but in the start of the "boosted" road. I'm definitely doing det cans, and like the idea of a cheap electronic fix over garden hose. |
