N1k2-j Wep

The Niki uses the same engine as the Frank but it doesn't have WEP for its second stage supercharger.

What is the reason as the TAIC shows it does.

The IJN and IJA used different boost specifications for the engine.

Also, keep in mind that there are many different versions of the Ha-45 with different critical altitudes.  Just in the Ki-84 at least four different such engines were used.

My Suzuki DL650 uses the same engine as the SV650

The DL:
produces more midrange torque
Has a lower RPM limit
produces Less MAXIMUM torque

This is because of
Slightly higher compression
Different Cams
Different throttle bodies

WHY:
because the SV650 is a "Sports Twin" and the DL650 is a "Euro Tourer"

Mind you I can still give an SV650 a good race to 180+ and I am a dam site more comfy after 800K + in the saddle

LOL!

Gotta love the connection, but non-riders just are not going to get it mussie.

Oh, well, gonna take the Victory Hammer out for a spin.  60 F degree day in Colorado Springs today.  Might drop by the Kawasaki dealer and see when he expects the new C-14 in.  Really thinking about the new Concours to replace the ST1300.

Ride Safe!

Soon to de-winterize my TT 600.

I almost traded in on a GSX1400 yesterday.....

[kreighund]

Are there any supporting documents for this difference?

[Karnak]

Yes, many, but they are in Japanese and I do not have access to them.

I have read translations, but once again I do not have current access to them.

The most powerful version that saw widespread use was the Ha-45-21 which peaked at 1,990hp, with good fuel.  That is the engine our Ki-84 in AH has, but it is running on the crappy sub 87 octane fuel the Japanese used in service so our Ki-84 falls far short of the 420mph recorded by the American tests.
