Try posting on a truck towing or Suburban board. I'm sure if you searched 'Suburban' and 'Vortec' and 'supercharged' you would actually find an interested audience to get snippy with.

I've always found that amateurs fooling around with well-engineered vehicles make them more unreliable. But...the experments are fun to watch...from a distance.

Is that the input you were looking for ? If not, then not sure why you posted here.
