    I've seen this on a 450 motocross bike, it was from a cold engine, bike was sitting for about 45min during an ambulance wait then the ref gave zero notice and started the race...

    Turbo or Super charger? Which is more "turn key"?

    if you change elevation a lot the superchargers can take a bit more tuning because you can't adjust the boost to compensate for altitude so your clutching needs adjustment

    Nytro Engine Rebuilding

    Unless you had a major failure the bearings should last a very long time... I pulled mine apart at around 4000 miles to forge it and everything was like new, i just honed the cylinders for the new pistons and ended up putting the original bearings in the new rods

    Twin charging make sense

    This is doable but you wouldn't want an off the shelf turbo kit. You would want to size the turbo for what your engine acts like with the blower (Say on 6psi your engine moves as much air as a 1500cc engine), then you would size the turbo to meet your power goals on that engine and plumb your...

    Having Issues with USB Cable

    i battled this for hours, reinstalling didn't help. Finally went into the control panel and found the list of USB devices and the rb3 had a different mark beside it, right clicked and hit troubleshoot and i think it asked for the cd and reinstalled the driver, worked ever since...

    Choosing a turbo for sustained operation

    i see, well continuous running @ 200hp shouldn't be too hard. Most guys that use those weldels i was talking about in car applications for many miles without issue and never add any extra turbo hangers, mine included and they hold up very well, their only downside is weight. You shouldn't need...

    Choosing a turbo for sustained operation

    Use a thick wall header (weldels are cheap, easy to work with and very heavy duty) and ceramic coat it. Use lots of heat tape and venting. Size your turbo to run in a very efficient part of the map and use a large a/r turbine housing. Use a large intercooler with really good ducting and airflow...

    nytro crankcase pressuring?

    While trying to sort some rb3 issues out the other day my turbo nytro started burning wicked amounts of oil. Pulled it into the shop fearing the worst (RB3 issues were causing it to go brutal lean) and pulled the turbo off first - there was oil in the intake and exhaust sides. Inspected a little...

    RB3 Memory Loss???

    Started trying to tune my rb3 in better the other day and have encountered a strange problem. First i set a new min/max to match my idle vacuum and max boost then started to build a map. When tuning i would make great headway in one area then go back and make another change and the first area...

    Cutting a track down on a Turbo sled

    knife dipped in 50/50 oil and gasoline

    Idle issues...

    An unplugged or open circuit with the IAT sensor will do this, sled assumes it is -40C (or whatever the coldest temp the sensor reads down to, most cars are -40C) and will poor the fuel to it. This happened to me on my nytro, took 1/2 throttle to fire it up and 1/4 throttle to keep it running in...
