VPC map sensor 2bar?

[MK3Brent]

I was going through some of my VPC documents when I came across this:

I've run more than 24psi before with my VPC, and had no problems.

The real question is; Where's the limit?

 

[dumbo]

And is yours still accurate?

5v on the map sensor... probably 2 bar of boost.

 

[MK3Brent]

So what's the highest boost anyone has ever run on the VPC?

I've done 20psi through my jt61gt without issue. I thought there was a way to use a GM map sensor if higher boost was required? Or is my mind just wandering again....

Well, just ran 26psi on mine.
Car ran amazingly smooth.

We installed some new fuel lines, fuel rail, and 680cc injectors.
Running really strong. We're going to dyno the car on July 18, so we'll see.

It will just stop adjusting anything once over it's maximum rated PSI Brent, most times you're rich enough up there not to have any issues.

I used to run 28psi on the T61 with the VPC, and I second what Ian said...

Looks like there is a 1bar, 2bar, and 3bar sensor for the VPC, but no idea how to tell what you have. But I think it is kind of like when you use FCD to go past 440rwhp on a Lex AFM setup, sensor does not read the air correctly but you are already rich enough that it will carry you past the readings.

I've run 34psi on Vpc before no issues.

Sorry I didn't get any thread updates in this thread.

Thanks for all who posted; Ian, Brian, Seth, Vic...


If I'm lucky, I'll blow something up this weekend and get it on camera.
