After playing with this site http://not2fast.wryday.com/turbo/glossary/turbo_calc.shtml?FeetASL=10&Tamb=21&Bore=114.3&Stroke=139.7&nCyl=4&RPM=600&VE=67&Boost=16&Ec=65&Eic=0&PdropIC=0&TambIC=21&wiPercentMethanol=50&wiRate=100&wiTemp=21&SFC=0.55&AFR=14.7&maxInjectorDutyCycle=85

I was trying to size a turbo for a 12/2, and the smallest common turbo that I know of only fit a 6 cylinder configuration. While a 6 cyl is more than I need maybe someone else could use the extra power plus an inline 6 is perfectly balanced... a turbo 6 would easily yield about 50 to 65 HP without an inter cooler, and about 80 HP with inter cooling.

The idea would be to use as many 6/1 or 12/2 common parts from India as possible, and make the crank case, crank shaft, and cam shaft here is the US.

Lastly a turbo on anything less than 4 cylinders is hard to do as there isn't a cylinder waiting to take the air charge. Ex on a two cylinder when one cylinder is venting exhaust to drive the turbo the other cylinder is already in the compression stroke.

However it may be doable with a tuned intake plenum, IE a chamber to store the boosted air charge untill a cylinder is available to take it.

Any ideas?
