    Nitro superchargers... good or bad?

    Yes the intake and boost ports do close before the exhaust port, but you must realize that these engines do not run at 100% volumetric efficiency at any point in the RPM range. If you increase the crankcase pressure using forced induction, you will boost volumetric efficiency, as well as the...

    Nitro superchargers... good or bad?

    If I had the money and time to do a proper test I would. Until someone who meets those credentials shows up, everything aside from the very limited proof offered by this thread is pure speculation. The RB supercharger doesn't work well on a Force 26 using one pipe/plug/head shim combo. That's...

    My buddy's crazy rubberband gun.

    I have also built several potato guns, but I always try to avoid doing anything half ***ed, and a traditional "Spray in the propellant, close the cap" system was too inaccurate for me. Hence the propane meter that injects a perfect 4.2% propane into the chamber, forming a stoichiometric mixture...

    Nitro superchargers... good or bad?

    I wouldn't say buried. You can't just strap a SC to a single engine, do a small amount of testing without using any actual measuring equipment, and call the concept busted. All a SC is doing is increasing the volume of fuel air mixture inside the crankcase, essentially the same thing that...

    great engines

    As purenitro said, Picco, but only if you are a good tuner. The carbs are very responsive and don't take kindly to the tuning styles of most inexperienced people. As well as lasting longer, the Picco will be a better performer. My Piccos both have pretty conservative crank timing, but in my...

    I've considered building an R/C snowmobile and powering it with my other Picco 28. We'll see, probably not living here for much longer as the town is dead.

    The only Savage owner in northern British Columbia here. The 14 foot annual snowfalls leave only 6 months of good R/C driving.

    I call it... Psychobasher

    Well, after a very lengthy rebuild, my truck is finally ready to bash again. Too bad I have no fuel and will not be going to the not so local hobby shop until Christmas.:duh: :duh: :duh: Power supply: Picco 28 Ofna 086 pipe Ofna short buggy header Double header retaining springs Motor...

    De- anodizing

    A saturated solution of sodium hydroxide in water removes HPI anodizing in less than 3 seconds. You can find it in solid crystal form at most hardware stores. If you can't find it in pure form, Drano is ~60% sodium hydroxide and works almost as well.

    Ouch! Looks like it's time for some IRC TVPs, a tank guard, and a better roll bar.

    dead glow plugs???

    The hot plug may be advancing your timing too far and causing detonation. The shockwaves produced would do a fine job of smashing the plug's coil apart. As purenitro said, try a cooler plug.

    engine sealing

    The slide to carb connection has a tendency to leak on most engines. Being 2 metal surfaces, you wouldn't expect a perfect seal. The rubber boot is supposed to provide a seal, but it can also leak. You can seal it by applying threebond 1211 or RTV silicone to the surfaces it is designed to seat...

    Damn... you should apply some kind of dry lubricant to those cups next time. That pretty much eliminated wear issues for me. Those FLM dogbones really aren't that much stronger than stock, because the S7 tool steel is annealed. When tempered it has a yield strength of 220,000psi, and there is...

    Picco P3 .28

    Good choice. That's the best Savage engine you can buy short of a Nova 528 8 port or an RB 928. As far as tuned pipes, go with an Ofna or Dynamite 086. The Buku is overrated IMO, and overpriced for what it is. I'm not saying it is a bad pipe. Basically, when you tune it to perform optimally...
