i'll agree a turbo is generally the best option for a street daily driver truck (btw, dog's truck is NOT his daily driver so a SC makes more sense for him), I would LOVE to have full boost at 1800. the higher your volumetric efficiency the better (more efficiently) the motor will run.

 

Not sure if you've seen hemi torque curves. damn motor makes almost full torque at 1500!! and redlines at 5800 or something. a single turbo is going to match that torque curve?

ever wonder why diesels have twin turbos, or one variable vane turbo? or why porsche spent years developing a variable vane turbo for a gas motor?

 

Have you ever drive a v8 with a turbo on it? You guys crack me up. I would be happy with the torque peak right around 3,000 rpm or so. Massive torque at low rpm=wheel spin & broken drivetrain parts. I do agree with you though, variable vane turbines are a thing of the future, it is a shame the people are just now adapting them to large displacement engines.

And yes, a single turbo can give you all the usable torque you could ever want or need.

 

I can't wait for Kennebell to come out with theirs. Nothing like having 500+hp and still get 20mpg's on the highway if MDS is activated. I bet MDS would actually be very useable with a twin screw or any added FI due to the extra volume of air still created even when not getting into boost!


Twin screws I was reffering to Jordan5.7, roots type just creates heat and are very inefficient.
