I've done some research on the Novarossi Engines and found out there are some differents on the cranshaft of the racing engines, please give some advise on what is the differents on these two cranshafts.

The one with one "V" intake is from Flash 12-3 and 353 Racing 12; and the one with two "VV" intake is from Flash 12PT and Keep-on 12. I am running the car in Hong Kong and a short course with straight about 40 metres, thank you.

I think you should go for Flash 12-3 and 353 Racing 12. This is a special Tuned Crankshaft. Made to meet even the highest standards of our most demanding drivers. and these crankshaft is made from high quality steel and is available in "TURBO SG" version.

I have had/raced all four engines and for the track you describe-- very much a low speed high torque track-- I would go for the Flash PT!

Next choice would be the Flash 12-3.

The Keep-On is very smooth but I'd think you want explosive not smooth. I love the 353 but for very big tracks with a focus on high speed power.

About the crank turbo cut that you are calling the "v" or double vv when I open all four engines that v part looks the same essentially, but the PT and KO have balence weights. The later models seem to have a longer run time (better fuel economy) but I am not sure if this is because of the crank balancing or other.

The PT and 12-3 if you tune them right have the grunt you want. If you get the 12-3 add .10 shim as the two I had detonated even with 16% nitro fuel.
