Ford/ NH 8240 SL Engine

I was reading up on Ford/NH 8240"s and I found this on another forum:
The transmissions are fine if they are ran at the horsepower they where designed for, but as we know there isn"t a 8240 or 8340 under 150hp in the world. remember the pto hp for a 8340 was only 112. The weakest gears are 9th and 10th if you can stall the motor in those 2 gears on a warm tractor the transmission will be fine.

My question is what was done to increase the HP from 96 hp to 150+? And is there any way to look at mine to see if it"s been modified?
Thanks!

Nearly all 8240s over in Great Britain have been turboed as they were real dead compared to the 8340. The diesel is real easy to 'screw up' on them also. We found the SL dual power gearbox to be more troublesome than the SLE gearbox, though a harsh operator could take the teeth off the dumbell gears on the SLE if he didn't wait for the range change. The big problem with these modern gearboxes is how much power the gearbox saps....The SLE gearbox can sap as much as 40 hp!
