Help!! rev car and lose vacuum and car shuts off
So I just turbo charged my 1993 miata and I'm having a problem with losing vacuum. It starts and idles great but when I rev it it looses vacuum and shuts off. I already plumbed in the idle air control valve into my intercooler piping. Could it be from an intercooler leak or what other vacuum could it be coming from. Than you!!

Could you post some info about your build? If you're running megasquirt, post an MSQ and datalog

I am running stock ECU and could the problem be that I did not put the air flow meter box thing back on?
And turbos don't work with our stock ecu properly. Are you familiar with a device called an o2 clamp? And you can't use a BOV with the stock ECU ever. Get a megasquirt and solve all of your problems. |
so you installed a turbo, and kept stock ECU with no added fuel, and no fuel/engine management? and did not install the MAF?
how do you expect the car to run with no MAF? once you install MAF, the car will run, and as soon as you go into boost, the car will go BOOM. |

This sounds like a direct result from those "how to turbo for cheap" you tube videos.

A VTA BOV with an AFM usually means it stalls out whenever the BOV opens. Maybe he's got the spring in it screwed down really tight and it stays closed mostly. It would be the exception and not the rule.
