Building the Nytwinder

[Dan Lance]

Intercooler mounting tabs done. Using a pump from Mercedes to circulate the intercooler coolant.

Some of the pics show the Tapp primary clutch. Running the stock secondary with Ulmer helix, Dalton orange/black spring and thunder products rollers

Started installing the Nytro harness into the Sidewinder chassis. Extended to reach the Hurricane upgraded fuel pump in the tank. Shortened here and there. Modified to run the intercooler pump, the Snow water meth controller, the Boost-it AIC, the Boondocker EBC, and the Dobek Gen4 AFR controller. Antigravity battery and freeze proof relays installed as well. Battery is in the nose.

Mocking up the intercooler plumbing. Tial BOV. Some heat shielding installed. Cold air intake tubing installed under intercooler.

Here’s some misc. pics. Munster finger throttle. ARC levers. Mohawk skis. Snow flap. CR racing hood. Skinz bumper

This is full of fuel, coolant, oil, 2 spare belts, tools, etc. ready to ride. Weight wasn’t the main goal with this build. Durability played a slightly higher role. I know I can install a lighter muffler, some tubing can be made lighter, couple pounds here and there.

Ridden a few times. Not sold on the Mohawk skis yet. Boost set at 10lbs while I sort everything out. So far it is very impressive. The combo of the turbo and stock compression is spot on. Instant response. AFRs have been dialed in nicely. Need to rebuild my Tapp before I finalize clutching. Had a bad ignition coil the first time out so that trip was null. Rides very nice. More to come

Whoa! Nice!!! You were busy!!!

Wow, I got a backache reading through what you had to do. Congrats on your project, that was a lot of work and I am sure it is infinitely satisfying to have put so much into it and have such an enjoyable outcome!

Nice build, looks like a lot of quality pieces. What do you think you have for horsepower. Good job!

 

[Dan Lance]

140hp stock. 10hp per lb of boost. So running about 240hp currently. I'll start wicking it up as I get little things sorted out. Should make more Hp per lb of boost than a stock Sidewinder due to the less restrictive and always cool intercooler. The larger more efficient turbo not working very hard compared to the smaller stock unit being over worked and heating the air excessively helps too. Most MTX winders I've ridden with leave a diesel like trail of black smoke behind them after the intercooler gets iced over. The plastics around the muffler outlet are always stained black.

Did the motor drop in to factory mounts?

 

[Dan Lance]

Yes. after removing a simple tube spacer from between the rear mounts on the nytro.

Hmmm that means an Apex engine would drop in…. I have a sidewinder with no motor and a spare apex engine…
