Wow we have the attention of a piston engine builder.
Gellener would never ask this.


Lycombing T55 the big brother of the t53.

It powered the Chinook helicopter, Ya know the one with the two massive Rotors.

It came in various versions. L7, C, B, or L11.It is also a Turbo Shaft engine.
it is the most commonly used and preffered choice of Hydroplanes.
The 7 series are rated at 2400-2600 SHP.
The 11s are rated from 3300 to approx 3750Shp.

They i beleave have 7 stages of axial compressor blades compared to the t53 at 5.
There dry weight is 570 on the 7 series and 670 on the 11,s.

In its 11 series configuration combined with the chinook CH47
it could carry alot of Coronas.

Would you like to cross over to the Dark side Jeff?

So 3 of the 11's should get my Nortech running pretty good.

TWO would put that thing above takeoff speeds

I would do 2 t 53's.

You think I could keep my # 5 drives or would I need the 6's? Where I boat I almost never get the boat out of the water, it just is never rough enough to get 20,000 lbs out of the water, and I have never had a drive blow yet on this boat with 850 hp.

#6 dry sumps with scheduled inspections, Arnesons or BPM's.

Here is an install done on a 50 Nortech by Marine Turbine in Louisiana. There are a few more of these running around that what some may think.

6 Drives are the Weak link!

Hows the Chrome tip look?

It just cleared the hatch..Actually I had to alongate some of the holes.



Is it more aggresive then 6 inch Stellings?

They'll even look better with some exhaust heat rising up through those things.

You mean like this?
