Nyper build thread

[Nikolai]

Wrapped up the heat shields and finished cleaning up all the pieces.

For the plate the header goes through I drilled and tapped additional holes in the chromoly tube so I could use the same screws to secure both pieces and save weight on tabs and fasteners.

Lower heat shield in place.

Both heat shields. The top piece has insulation, the bottom does not so it will gain a little weight. The steel bolts will be replaced with aluminum.

Need to pick a material and make the sides of the tunnel now.

When I was planning the build I wanted to keep the heat shields under 1.5 lbs and all the tunnel skins/enclosures under 4 lbs, that would get me my 50 lb frame with the complete cooling system.

.040 7075 upper piece is 1.06 lbs
.040 7075 front piece is 0.93 lbs
.050 2024 header piece is 0.39 lbs
.032 5052 heat shield support is 0.11 lbs
Heat shields w/ steel bolts 0.77 lbs

At 3.26 lbs for all of it right now. So I have 2.24 lbs to cover the sides of the tunnel.

I need to start thinking about a fuel tank. My plan was to weld one up out of aluminum using a mix of .063 and .080. I’ll get a fill neck and cap from Wahl Bros, and use the fuel tank string foam to control sloshing and save weight vs baffling. Where I’m stuck is the fuel pump. I don’t have a way to machine my own adapter to take the Nytro fuel pump.

I’m thinking an external fuel pump may be best/easiest here. Anyone have a recommendation?

Edited: Found an old thread recommending the MSD 2225. Can anyone confirm if these are good?

Worked on enclosing the tunnel some more. Had to do a little filler piece up front on the clutch side. Used .040 7075, this piece was 0.15 lbs. The rest of the inside from the bearing holders back will either be thin HDPE or single layer of carbon fiber.

Order up a wallbro gsl 392 best pump for the nytro turbo I have went thru a few msd pumps before I started using wallbro. Don’t worry about using stock nytro pump as it is close to not enough fuel for the turbo anyway. Just buy some wallbro fuel pickups. one in front and one in back and your good to go.

Get a Walbro GSL392 pump, use a relay to power the pump from the battery and use the fuel pump wires to activate the relay. You'll also need an adjustable fuel pressure regulator as well.
