Default Variable Nozzle Technology

Hi Guys,

I was just checking out the VNT Technology on the Honeywell Turbo page and was wondering if there would be another way to do this.

I was thinking that an additional really small throttle body could be installed between the turbo manifold and the turbo inlet and be connected to the gas pedal to do the same thing? Or would it just kinda make a lot of turbulence and such?

Thanks,
Keenan

Dang, I thought I put in a link. Go here to see what I'm talking about. Basically the turbo inlet is smaller at low RPM. Meaning that with less volume to fill, the pressure produced would be close to what it is at full throttle. As your RPM increases, the turbo inlet also increases so your engine doesn't get clogged up. It's like having a small turbo at low RPM and a big one at high RPM.

I didn't explain that very well but maybe you'll get what I'm sayin once you look at the site.

I think the only way to get this effect would be with the VNT. If it could be done as easily as, let's say with a butterfly valve, I think that is how the engineers would have done it to start with.

I could be wrong, but usually these things are made with good reason. For example a butterfly valve probably can't regulate really high pressures. :dunno:

Yeah, you're probably right. Maybe the butterfly could be made of some really high heat metal or something. I just always have to question things and try to do things a different way then you're suppose to. I really doubted that it could be done differently when I first made this thread but it's always fun to think about stuff.

Thanks,
Keenan
