I c what your talking bout has extra holes for a different mounting configuration, intake splits apart at the center for future crank case design

4 of the bed plate case threads were pretty much eaten away by corrosion and stripped out. Tapped them for 12mm and loctite all of the bolts this time.

Back on the water yesterday. Huge improvement with the 7/14 and 92mm nozzle.
Finally got in these...
So I should have these finished by the end of the week...
And finally your weekly dose of carbon porn, blue kevlar-carbon coupler cover.

Definitely made a big difference. Gets on the pipe a lot sooner now. Thanks!

What are the first things that you got in? looks like a heating pad of some sort? Did I miss something?Back on the water yesterday. Huge improvement with the 7/14 and 92mm nozzle.

Yes. Those are foil heaters. They will be infused into the molds and used to post cure the parts rather than using a 1500 watt IR lamp. Ultimately the goal is to use prepregs and a B side mold for the smaller parts. I would love to produce some beautiful visual flame arrestors for sale, but the time involved with infusion just makes it impractical (unless a $300 flame arrestor is in everyone's budget). Integrated mold heating is the first step towards lowering cycle times and ultimately the cost. I don't know if It will ever become a reality, as the prepreg increase material cost and just about offsets the labor saved. It's a good learning experience though and will save energy and make curing infused parts much easier and precise.

Anyone with an RRP bracket and an 8" mic mind taking a couple of measurements for me?

Would the flame arrestors mimic the stock superjet one or the aftermarket ones?

They will mount on AM carbs or carbs with AM adapters. They will be similar to the OEM boxes, but with drains and a slightly raised air intake so that any water that gets inside can drain out instead of down the carb throat.

Still need the inside width of an RRP bracket. If anyone could help me out with that, it would be appreciated.

Nothing related to the ski really. It's torn down right now waiting on new pipe, total loss, and high compression domes.
Flame arrestors were too tall for this hull. The hood lip is just at a terrible height that interferes with just about any FA. So I'll be rocking my SS 12 mesh and hose clamps for now.
(In the background)
Also the infusion failed on the parts, leaving a rough looking finish. The one time I don't leak test the bag is the one time I have a leak. Go figure. I'm still going to clear coat it and post a picture.
I highly doubt I will ever produce these for sale. Using a wet layup and b side molding compressed into the laminate is the only time effective way to do it. Infusing takes about 5-6 hours total (3 parts to these). Wet layup with a b side would take ~2 hours. I do have files to have A and B side molds CNC cut from aluminum blocks, but the upfront cost is pretty high. I would need to sell ~50 units at $125 per flame arrestor to pay off the mold costs. It's not a good investment right now. They do look pretty badass though.
Focus right now is getting the last details on the poles done so we can start selling them. Here is the last test pole.
The first production pole is being made now. Had to revise the layup in order to fit the breather location on the rrp bracket. Custom bushings are being turned from Delrin and custom pinch bolts are in the works. Going to either layup a final visual layer of either honeycomb or 4x4 twill. I wanted to do 4x4 V twill, but my supplier was out of stock.

For sure Matt! If these take off, I'll probably design a shorter one. Have to see how they sell. There's been a lot of interest in them, but a lot of interest doesn't always translate into a lot of sales. We will see.
Also working on something else really cool...
More details when I get a prototype done.
