Parker Nytro Turbo Pics

I like the timing thing as well so what is the limmit to the timing box as far as max boost is it the same as a head shim???

 

[Parker]

Knock as it is commonly called is actually two different things, detonation and or pre-ignition.

Detonation is the air fuel mix in the cylinder burning to fast or rather exploding instead of burning, but is still ignited by the spark plug. That can be controlled by pulling back timing as the boost and cylinder pressures rise.

Pre-ignition is the spontaneous igniting of the air fuel mix either from some hot spot in the cylinder or from compression ignition. That we control by keeping the drive pressures low, creating a good map with no lean spots in the fuel box, and keeping the charge air cool. There are two ways to keep charge air cool, the obvious one is an intercooler and the bigger the better. The other way is not to heat it up too much in the first place by using a proper turbo match.

So at 5000ft what is max boost and still safe with Av gas???

 

[Parker]

What does everyone else publish for specs on their kits for Av gas at 5,000 feet?

 

[KC Boost]

10HP per PSI of boost is a rough guide not gospel.

Every filled cylinder is not equal, even when at the same pressure.

Hot air contains less oxygen than cold air. A turbo is a compressor, what would happen if you ran your shop compressor at double speed, the air would be hotter and contain less oxygen. Turbo's and superchargers are the same they all have an efficiency map, the island in the middle of the map where it produces the least amount of heat into the charge air. A proper turbo match runs up the maps peak efficiency island, away from the surge and choke lines. To small of a turbo and you over-speed it running it off the map create more heat than you want and can push it to choke where it won't even produce anymore air or power just engine damaging turbine back-pressure. To large of a turbo and you get really annoying on throttle surge, where the compressor is producing too much air and the turbine side can't keep it driven so the air backs up in the compressor and slows the wheel down or stalls it. On throttle surge effects performance, spool-up, and turbo longevity.

Also higher compression engines need less boost to make the same increase in power as ones with lowered compression engines.

thanks for your knowledge. I am curious about your phazer kit, hopefully see one work this winter

Had her on the snow for the first time, it spools up so fast and has so much torque that it stands straight up in 10 feet.

So parker lets see some more details and pics man . You need a little more info on how it ran

 

[Parker]

My wide band wasn't working and thus I didn't get the testing done that I wanted to with my Data Acquisition. I'm recording RPM, Fuel Pressure, Boost, Inj Duty, Knock, and Wide Band. All I can say is the torque on this thing is unbelievable. It takes off 2 stroke fast and spools instantly. All due to stock compression , header design, turbo match, and CAC design. As soon as I have the last piece of the puzzle sorted out I'll let you guys know.

ya to bad synergy couldnt do the same!!!!!!!

 

[summitking]

i agree with you stray i havent heard from mitch in a long time and he has my dads sled

 

[STRAYPUSSY]

hummm thats not good id have to say

 

[Parker]

I put up all the good pics, the sled looks stock with all the plastics on it, everything is hidden, I could link over to Yamaha's site, LOL. I'm riding again this weekend and hopfully my Innovate LC1 will work and not screw up again this time so I can get all my real world AF ratios tested and adjusted.

 

[winter]

Please tell more

I am very interested in this set-up, it seems to be clean and well thought out.
How did testing go this weekend?
How is the exhaust routed?
Any idea on cost for a complete kit?
What are the fuel requirments/lbs Boost?
How about the fuel tank?
Thanks.
Winter.

 

[Parker]

The testing went great, I'm making some mods to push the boost higher and see where she'll go to. That is the best boondocking setup a guy could ask for instant boost, lots of power, and a chassis that handles great.

 

[Parker]

I still can't get used to the acceleration, it's scary fast I cancel my nitrous kit I had on order. On hard pack hard acceleration It hits the rev limiter at 9400 and runs to 10,400 before it comes back to earth. In powder it stands up in it's own track at 10 PSI and runs through the whole map between 12.0 and 13.0 on the WBO2.

I run a couple degrees advance off boost and retard it as boost comes on, the advance makes the bottom end peppy.

 

[summitking]

So are you advancing it even with the stock compresion That would make it really snappy

 

[Lunch_Box]

That there is smart.

 

[SNOW JW]

Just a quick question what would happen if say the Timming box took a dump in the middle of a climb???? Is there a fail safe system to help out so a guy would not scatter the motor??

 

[HPCrazy]

Keep up the good work. How about a little promo vid clip. You know a good kit with no bugs priced at about 4g rather than 5 or 6 would simply take over the turbo market!! Time to hire the manufacturing line of fabricators.

The company that makes the fuel control box has been around for a very long time and makes a very superior product to most I've looked into and that's lots over that last 4 years since I started down this path.

But to answer your question the same thing as everybody's fuel controller including the one that came on your sled from Yamaha if it goes haywire you could lose a motor.
