Will believe that Martin Truex Jr buy this new engine so will be break record over 150MPH
 
The M-Line 45 will, maybe, make a tenth or two more HP than the RS EVO.

It'll be available mid November.

The M-Line 91 puts out 7.0hp @ 27000 rpm... 1/10th more than the 91 and 101

RS EVO's.

The M-Lines use a special piston and liner, new design Crankshaft, Billet front

housing with one needle bearing and one ball bearing plus a Turbo head button

and 6 bolt Red water cooling jacket. Bearing setup is designed for square drive

application. Looks to me to favor endurance racing.

$693 for the 45, and $853 for the 91.... I guess one could upgrade the 45 RS EVO

to 45 M-Line performance spec with the piston/liner assy. and turbo head button

for ~$200.

William.. how does it run.. any US reports?
.45 M1 P/L kit runs great, no complete M-Line motors (.45 or .91) being ran in the US that I’m aware of, don’t think they are being imported due to the DFB requiring square drive only.
I have a .91 M-Line engine but have not ran it yet.

I talked Tony Australia about 91 m-line it can use both collet and square. Not arrive new CMB45 M-line yet because factory workers delay from Covid-19

There is no clip holding the bearing in the housing, push on it if you want to.
Did you order First version Early 2019 91m line at your first USA ? Only low nitro and only square drive and gear drive
I read update version latest 2019 can use both collet and square drive
