Hey guys im a noob and was wondering if i can get some help. I have 90 miata equipped Aerocharger turbo. The car drives normally but isnt getting any boost. I do have vacuum pressure but barely hits zero. Anyone familiar with this turbo? Thanks

wil,

heres a link on what kind of turbo it is-http://aerocharger.com/

 

Post some pictures. And more info. What type of engine management are you using?

 

i think a stock engine management system. i bought the car with this problem.i dont have pics at this moment.but heres a link to how it exactly looks like. Aerodyne.

 

Is the turbo seized up? Is the waste gate stuck open?

Post some pics, we can't see much in the pic on the link. Yours may be slightly different.

 

sorry for pic. I was told the waste gate was stuck open but this turbo doesn't use a waste gate. it uses a VATN (variable area turbine nozzles).

Wilson,

 

i doubt the turbo has seized bcz i still here the turbo spin when give it a little bit of gas.

 

sorry i wish i could post better pics but the car isnt with me right now. I could post some pics in a couple of days. uhm I dont know what else to say about the car. It runs great but just isn't getting any boost. anything i could look into to see what the problem is??thanks

 

Read the FAQs and stickies on this forum. It will give you an idea of what's required to turbo a miata. Then look and see if you have all the parts required installed.

 

thanks. appreciate it

 

your username lies.

never used/seen an aerocharger turbo in person. I would think twice...no ten times before buying an untraditional turbo.

 

No boost could be as easy as a coupler leak. Have you gone through the whole charge system and checked all the piping, couplers, clamps?

Also, put your location in your user profile... maybe there's somebody local to you who can come over and take a look.

 

+1 on blown pipes, although he said it "runs fine". Assuming it actually does, it'd run very poorly with a blown pipe, although give the exactly symptom's he's describing. I had that happen at the track, and I barely made it up to 60mph, and I was a sitting duck until I limped back to the pits.

 

Those kits ran on really low boost. He might have a loose coupler that only leaks when pressureized, but seals fine in vaccum.

 

I heard Yugo was going to use those turbos on their production cars, but they found it didn't meet their reliability standards.

 

Every Aerocharger fails; yours is no exception.

Call Corky Bell at Bell Engineering and see what he suggests.

 

I have never heard of Aerocharger.

Is that weird?

 

aerochargers were self-contained variable vane turbos, cool ****, not the pinnacle of reliablility

 

Check your couplers for leaks.

 

5.5k for the polaris RZR kit, you've gotta be ******* kidding me. This **** is real shady.

 

Thanks you guys i really appreciate the quick responses.ill go ahead and check it out.
