What he is also not telling is that we've been chasing a fuel system "ghost" for the past several months that was causing his fuel pressure to drop at WOT at high RPM's. With that sorted I figure he's got something more in the bag.
BTW: The Dart Pro -1s are CNC 335s and the camshaft specs are pretty large (sorry Ian!).
I'm convinced that this boat can do more (poss. 95 +) with a bigger prop, as is.
AND he did all the mods himself and this thing has been running reliably for at least the last three years. He even runs it across to one of our sister Islands (a 90 mile jaunt through deep ocean) at least once a year!
If you doubt how this thing runs ask Gary Ballough (I suspect you might know him) he had Ian breathing down his neck in a triple 2.5 Drag powered 30 Spectre the MDR Poker Run year before last.
AND he kicked Andreas Ugland's (remember him?) a$$ in the calmer water in a SeaTek powered Buzzi race hull!
How's that for an old home built Formula 272.
BTW: he beat me up a couple of times too, but I'm gonna get him back one of these days!

Re: More speed please
Shorties , I would say definitely helped in my mind. 7 mph by removing the Silent Thunder WOW that's incredible. I did find out this winter i was never trimmed a high as I thought. I changed my tab indicator cables 2 years ago and they read about 2 numbers off as compared to before. # 5 used to start + trim now it's not till #7. This means when I was running #6 last year I was barely 0 trim much less any + trim.

Did you remove the silent thunder box after your engine upgrades? I'm thinking that sounds like a really huge gain for a stock engine. With all your upgrades intact though, the reduced back pressure probably made it come alive.

Re: More speed please
Mopower, I think you have some more mph hiding in there you just need to flesh them out. Interestingly my 93+ runs are with neutral trim, two people and a full tank of fuel. BTW I have never run race fuel in this boat, strictly 92 octane.
The shorties definitely helped, saw a 4mph increase but then I went with XR uppers which due to the straight cut gears that knocks off about 2-3mph so the net is only about a 1mph increase.
Anyway I am happy to continue the discussion but I am concerned that we have sort of hijacked Flatout's thread, sorry about that Flatout.[IMG]
