Well the Trustrum Family barbeque finally gets used this summer. Good thing too as this stuff smokes somewhat.
Its also a bit like Napalm. Its hot and sticks to skin. You have to rub it to roll it off.
I sprayed a bit of silicon down the transfers and poured the Vinamold down, poked it & refilled the sink holes.
I've since pulled them out & its been illuminating. Pics later.

Doesn't look pretty but works well.
Don't you look at my accountant.

Ahh I never posted pics, or at least on this thread. I learnt a bit, like how I made a trumpet shape when I thought it was an even tunnel. Also inclusions where I couldn't see.
I've had another stab since these first moulds and gone further to rectify the issues, then moulded again with more work.
Ran out of patience to mould a 3rd time. Just want it back together for the weekend.
Pics, see how narrow the boost was? Next mould was much better but not far enough but no pics of those.

Well its all back together, thanks Koba for the clutch basket I owe you something.
I think I'll just ride the next meet and see how it goes.

I like the mold idea, it looks very useful, expect to see Team ESE trying it some time soon..... Thanks.

Yeah melt it slowly, pour it slowly.
Well I'm ready for the next meeting. Hope I've got some power spread now.

How'd it go?Originally Posted by F5 Dave
I've had a quick skim of the results, I'm guessing you weren't on the 50.

First couple running in/avoiding wet track/getting pilot near the right size.
It's fast, but its too hard to ride. You lose lot of time coming on power. 'nother pipe required. Also I'd like to make the back of the B's deeper with more angle to the centre. Very hard with dentist drill.

Fuck I hate this thing. Dyno showed despite the careful transfer matching its barely struggled 21hp and compared to when first built 6hp down with 1500 thinner power band from an already peaky spread.
No wonder I was having trouble getting to the front.
So is it transfer mods or just some fundamental problem with an old highly unstd engine?

That's a bit of a bummer Dave, I have been watch this exercise with interest.
What are your durations? Or maybe your pipe spec is now non matching compared to the early build. Or ... Maybe it's breathing better but your intake mods are restricting it (carb/reed stuffer)?

The difference between October when I made the 3 port barrel and now is
1. crank rebuilt
2. transfers floor lowered to match piston BDC. Some filler on the inner wall to give them more curve and a slight tickle. All sorts of things that should improve things, not devastate power.
I'll leak test it again. It was pretty smokey on the dyno.
So the question is will the TZR engine fit an NF4? . . . .sigh.

Bugger. Hate it when you put sooo much energy into something to have it turn to sh!t.
To answer the TZR question. I would have first though Not a rats chance in hell.. Wouldn't fit in a NX or TZ... Though the NF motor is a little more like a MX engine so it might get close I'll have a look see over the weekend.

I hate it when that happens. Been there, and spent most of 2 years to get modest power out of an engine that was, I thought, gonna be super quick.
Just to cheer you up we've got 23.5hp out of Gary's motor and it's a sweety. The failure at Edgecumbe was the balance shaft ball bearing inside the gearbox disintegrating. How it never simply exploded I'll never know. It'll be all good for Tok'

27.5 at 12,000 was likely to build to more at 13000 when I built a new pipe. But no point. Hopefully the world will stop and everyone will die.
Looking on the bright side.
