Building the Nytwinder

[Dan Lance]

Here’s some pics and words from my Nytro engined Sidewinder MTX build. Picked up the rolling chassis minus engine and harness etc as the previous owner pulled it all for an experimental aircraft build. I had a Nytro motor left over from an earlier project. Motor is stock with ARP head studs only. No shim or thick head gasket. Running a Gtx2867genII turbo. Air to water intercooler. Evo flashed Nytro ECM for 550cc injectors. 440cc if I remember right secondary injectors. Water meth to keep deto away.

Stripped off the front upper a-arms and shocks to install a BDX Hypro front end. Shorter spindles and 1.5” raised height in the front.Added HD tie rods.

 

[Dan Lance]

New brackets and upper arms installed.installed OTT bronze bushings in the steering pivot.

Started on the rear bumper and running boards. These parts came from CRracing. Coolant for the air to water intercooler will run through these. Inner tunnel braces and exterior braces installed.

 

[Dan Lance]

Lots of cutting drilling and riveting. Cooler installed.

 

[Dan Lance]

Started on the rear skid. Adding 174” Iceage bomber rails. Also adding Skinz ARC system. New light weight driveshaft,drivers,brake rotor, and belt drive will be installed as well. Stock rear 163” skid weight

 

[Dan Lance]

Finished skid minus Skidoo scratchers. Installed Camso Conqueror 2.8 track. Stiffer center shock spring from AC. Added the stronger cross shafts, Billet rear axle adjuster inserts.

 

[Dan Lance]

Had to add the speed sensor from the Nytro to the Sidewinder D-shaft so the Nytro computer will be happy. Mounted the sensor to the brake shield

 

[Dan Lance]

Belt drive installed. Had to space out the oil tank over the distance of the hardware provided. Had to cut down the baffles etc inside the tank to get the cover plate to fit. Had to trim the tensioner bolt shorter to clear the muffler. And had to buy a different jack shaft bearing than the one provided in the kit. Also installed the AC cross shaft to eliminate the reverse.

Some of the pics aren’t in perfect order, trying to show relevant data.

Installed the Nytro engine in and started mocking things up.

 

[Dan Lance]

Started fitting the Garrett GTX2867 gen II turbo and the Hurricane header. Also the PEFI muffler and the intercooler. Only using the top half of the intercooler. It has three additional injectors and will be welded to an air to water core.

 

[Dan Lance]

Had to cut off the Yamaha flange on the muffler and weld on a Garrett flange. Also cutting and welding of the tubing. Exhaust turbine housing was welded to the factory mount. Can also see the wastegate actuator mounted.

Here’s the air/water intercooler.

 

[Dan Lance]

Started working on the plumbing. Using the SC Nytro water outlet. Various stock sidewinder bits. If you zoom in you can see the water/meth nozzles on the throttle bodies.

 

[Dan Lance]

Water meth tank. Pump mounted under engine. Snow progressive controller running aquamist pump and nozzles. One for each cylinder and one for the turbo outlet when the boost starts going up. Installed the BoP skid plate. Also used their oil cap to oil cap vent relief on the oil tank.
