As some of you may know I picked up this beast early last summer from Mr. Linn.
Here was his build thread and progress, http://www.columbusracing.com/forums/showthread.php?t=89368&page=8
His goal was to break the 80mph barrier, sadly I don't think he ever did.
It was pretty hard on the limiter so I added 1 degree to the prop pitch, good for 1 mph. The fuel pressure was set to the moon in order to keep the big charger happy, so in went to some larger injectors (42lb to 48lb) and lowered the pressure a little. Rode it this way most of last summer and had some moments of high rpm, 8160+ so I was most likely hitting the 80 mark just don't have proof.
Now I'm taking things to the next level...
On to this season, I'm gonna say the goal is 83mph (GPS verified this time), but all roads lead me to believe the boat will have an 85 in it on "kill mode". 100rpm gained = about 1mph. As I can add pitch to the prop and go faster. Should be making about 350hp with these mods. Thats a 1.5 liter engine at 14psi spinning 8100rpm+ the whole time. :fuckyeah:
