The world is full of turbo experts who haven't designed or built a turbo system. Maybe the read a book?
in high school they told me I couldn't turbo my vw bug. I did, it worked.
Many years later I was told you can't turbo a 914. I did and it worked well.
I turbo'd a 911SC but that had been done before.
I supercharged a chrysler hemi, but that had been done to death.
Some folks say that if a turbo system doesn't put out at least a bar and double the hp it isn't a good system. bunk.
Yes there are many compromises on that design and many opportunities for improved efficiency. That doesn't mean it work work well, it only means it won't work as well as it could potentially work. I don't believe he's going to get the performance he expects but it should still work.
Forced induction systems offer diminishing returns. the first pound of boost provides more improvement in performance than the second, the second offers more than the third, and so on.
Maybe someone can explain to the group why torque curves tend to fall off between 4200 and 5200 rpm on most street engines, and what effect just 2 or 3 pounds of boost has on those curves?
That low of boost may not increase peak torque much at all but it will flatten and extend the curve and maintain closer to peak torque much higher into the rpm range. We all know what that means, right?
All engineering projects have compromises and trade-offs. Ask any engineer.
Sometimes you can't build what you want to build so you build what you are allowed to build.
The point is this:
if a cheap, simple, easy to do turbo system works and puts out a few pounds of boost without other trade-offs, it should be considered a success. Probably more is than a system that is extremely complex and costs $12k to install.
