Lots of labor for the whole deal.
Entire thing tore down. Main bearings, cam, lifters, a few rockers, timing chain and components, piston rings, reassembly, then a bunch of dyno time to break in the new cam...

It's kind of hard to show how much progress has been made in the last month. Because it doesn't look like much. But i can assure you i've had 5 hours of sleep every night for the last 30 days.
I am beefing this thing up much better than it was before
Engine rails in.
Hockey sticks to add support.
Hockey sticks in. Tube for wing wiring in.
Wing and new wing hardware being mounted in.
Making templates for decks.
Rough cutting up foam for decks.
Laying up the first set of decks. All that black velvet.
Vacuum bagged.
Stupid little hanger on the bottom layer. It's getting painted, so i wasn't worried about it.
Hockey sticks in, this is the cell that the skid fin is mounted to. Lots of beef.

It seems like a lot has happened. But as with any project, what seems like major progress happens in quick succession. Decks are on.
Looks cool now, until i tape in all the joints and start doing body work! Unfortunately i'm painting over all this beautiful carbon. Unlike what modern supercars would lead you to believe, high temperatures and direct sunlight absolutely wrecks the glue in carbon fiber. Plus, working on a black boat / race machine in blistering heat is not something i want to do, or would put my crew through.

Erats hydroplane thread update.
Honestly, just going to spare you the month and a half of bodywork updates and skip straight to the paintwork. Bodywork absolutely sucks. I burnt up 2 electric orbital sanders even taking good care of them.

Brushes on both. But I don't know what made them heat up. I blew the dust out of them after every use... But when they're $50 I guess they aren't meant to last.

I've touched 115 on the Racepack GPS.
At $1500 a prop, it's hard to justify a massive prop for top speed when we spend a good majority of time turning left. Our average lap speed is around 90mph on a 1 mile course so you can see how important is it to carry speed through the turn.

I bet there's data to be had that would suggest rear facing headers with a collector produces an amount of thrust that is greater than what would be provided by zoomies.
Regardless of all that. She's ready to go. Gunthersville AL this weekend.
He's being a smartass. He means the exhaust headers.
Yep exactly. I am an above average intelligence ******* that works for one of Erat's old competitors who saw gains by rerouting their headers out of the wind.

Rear facing headers are better than zoomies, but a fairing on the rear facing headers is better than no faring on rear facing headers. With the pic of the engine cover I see there's a kickout helping air flow around them already though. Like you mentioned a few times, consistency is more important than any of this. Good luck in AL this weekend, the boat looks great!
Rocker fell off, stupid ******* set screw setup. Should of been a jam nut at a minimum.
Beat the **** out of the lifter and in turn wiped out the lobe on the camshaft.
That was last weekend. Thank god i found the debris in the filter and tore it down Tuesday, because i was about to toss the rocker back on and raced it this weekend.
These were made specifically because our SBC hydroplane couldn't run shaft rockers, and because polylocks and guide plates are not ideal at the rpms you are turning. About $1000 more* than the scorpions and guide plates, but some amount less risk of wiped out cam/lifter/engine/race weekend.
*Available in steel if your sponsor is paying for it.

Oh come on, now you come off some secrets...
Now i know why them boys never lift the valve covers off them engines. At all! They even say they never check them all season...
If you're at liberty to say and if you know. What lash are they running? I've heard 2-4 but i'm up around .008 - .010 cold. I was always under the assumption that things close up when hot and at .002 there doesn't seem to be much room for margin.
I'm still running the scorpions, but i could easily swap them out and use them on the wet sump backup engine i have.
