After fighting with my boost controller all day to get a consistant 10 lbs, and *thinking* I got it working right (how's that for foreshadowing?), I went out to do some boost pulls and take pics of the gauge.

*sigh* I feel so impotent, but at least it's a cool picture...


It's a manual boost controller that basically acts as a restriction in the line going to the wastegate. Pain in the ***, I tell ya.

 

isnt a manual boost controller safer to use though then a electric one

 

Yeah if you can get it working right...

 

what MBC do you have? it should be fairly easy to tune. good luck and cool pic

 

i sold my dual sbc Blitz controller for 90 bucks on eBay, didnt need it anymore because i am going NA

 

i imagine you could run a large vaccum line and then cut a hole in the firewall and have the dial in the car if u wanted to cut a bunch...

 

MBCs aren't as good as electronic because at higher boost pressures, they cause boost spikes.

As for moving the MBC inside the cabin, that's not an option. That would cause MASSIVE boost spikes because of the ammount of line between the boost source and the wastegate. The turbo has to pressurize the line before it can pressurize the wastegate actuator. The more line there is, the more "lag" there is, and on a fast spooling turbo like mine, I'd probably see as much as 7 PSI fluctuation if I ran it into the cabin.

 

sweeeeet picture.... here's mine, too bad i'm in vac when i took the pic

 

what's that line in the top portion of the pic? is the gauge cracked?

 

no its liquid filled...

 

They shoulda filled it to the top

 

it's autometer they read like crap, get something better
greedy or hks,

autometers don't read right.

 

They have to allow for thermal expansion and contraction of the liquid.

 

hell yeah autometer suck...... i would get something better but funds are kinda low

 

Aside from the AFG they make, I disagree and challenge you to prove your statement.

 

i dunno about other guages, but wiht my guage i gotta reset it everytime the temp changes......sometimes the pointer will be in vac or way above 0... kinda anoying..

 

Loco Honkey....You got any pics of you set-up?

 

I've had no problems with mine in over two years. Ever think that maybe you just got a bad gauge and need to have it replaced? And how do you reset a manual pressure gauge?

As for my setup, I have a dirty engine bay, so I don't take too many pics, but here's a few...









-Home made tubular steel manifold.
-Hybrid IHI turbo: VJ11 center section, clipped turbine wheel, ported turbocoupe exhaust housing, Turbocoupe compressor wheel and ported compressor housing.
-Supah hi-flo "mo' powah!" downpipe.
-MX-6 GT intercooler.
-1G Eclipse BOV.
-Some kind of manual boost controller.
-Ghettofabulous charge piping.
-12:1 FMU.
-Bosch inline fuel pump.
-Missing Link.
-Greddy turbo timer.
-NAPA- spec oil lines.
-Autometer gauges
-Air/ fuel
-Boost
-Oil pressure

*edit- and of course, the nessicary safety placard:

there is a lil screw on top of the guage... they call it "venting" in the autometer instructions... sweet ride

 

Thanks! ^_^

I have the normal non- liquid filled boost gauge, so I don't have the vent.

 

Replace the fluid with lightweight hyper-guage fluid - works every time!


BTW where is that sticker on your car?

 

Passenger side dashboard. :D

 

Where did you get it. That's hilarious.

 

Some guy was selling them on Ebay for $20, but he posted the graphic, and not a picture like what you see here... I have a ton of people that want them, so I'm going to see how much it costs to print up about 50 and sell them accordingly.

 

Cool, let me know if you do that.
