What a wild ride this has been, quite literally. Lets start at the beginning...This bike was brought to us as a mostly stock 135 slapped into a CVO ST. Had some crank work done, a cam, and that that was it. And boy did we push it to its limit. As you can see 14lbs of boost from a Ben Lawrence turbo set up coupled with a M**hanol Injection Systems system did not play all that well with the stage 4 pistons, cracked them right in half. At that point "Scarlett" was making right around 305HP STD. No signs of failure were present but we decided to tear it down anyhow, seen the damage and got back to work.
From the bottom up we checked everything over, and satisfied with how well the Harley-Davidson components held up, we decided to beef it up a little.
Went from a dual nozzle methanol injection, to a single nozzle volute style. We spent countless hours working with Rodney at Pro M**h to get the delivery just right via nozzles and atomizers.
While we were in the engine we decided to beef it up a little bit with some Maxcell forged piston thanks to Southeast Custom Cycles, a few S&S Cycle goodies, mixed in some Fueling parts so on and so forth.
We at RedPond Cycles can't say enough good things about how well the LMF turbo set up works, from being styled to your wants, to fit and finish.
321HP/276FtLbs of torque STD on pump gas and 50/50 water/methanol, speaks for itself. This winter after riding season is over we will absolutely be building an engine capable of 400+ with the help of Vance & Hines Motorsports and Ben Lawrence
Lastly, NONE and I mean NONE of this would have been possible without Impact Wiring Solutions, LLC. We have tried the others and they just do not perform. The control from that ECU is incredible, Big, Big things to come while we venture down the road of methanol injection in your tractor engine.
You want it? We got it.
