I was tempted to fit some extra bits last night and attempt to jump to 15 hp, but then I realized that this is a demo kart, not a dragster! :rofl:

I can't seem to leave well enough alone... I'm working on raising the power levels again to make things more interesting. My biggest focus is cooling the piston on the gas and lowering the risk of detonation.

BTW, the piston looks practically brand new after inspecting it from the ports... nitrous is GOOD for engines! :yes:

Just finished the installation and bench testing of the additions: OK TO GO!!!

Only thing left is waiting for the paint to dry and then it'll be a wrap for testing at INCREASED LEVELS! :twisted: :twisted:

I hit a small snag after overlooking one KEY aspect to the success of the new additions (not actually new LOL). I won't reveal yet what I'm up to yet, but I will say that the need to aim the nitrous and fuel into the carb became absolute. While what I ended up with is FAR from what I really wanted to do (to achieve the optimum), I had to use what was at my disposal without spending any extra funds (I already spent the budget required for my goals).

The engine should be set for an additional 10 hp... 15 additional hp may be really pushing it, but I don't think anyone has ever discovered the absolute max this thing can take. I'll have to choose the settings on the minimax carefully.

Also there are absolutely no mods on the engine at all. Although it would benefit from some exhaust porting, but to keep true to this concept I'll leave it totally stock.

Oh god this is crazy... :drunken:

This engine LOVES nitrous! Went for a 7-7.5 hit and it was gooood. I did try higher hits but I'm having some trouble matching the nitrous flow and I think I know why, I just need to confirm: it was running way too rich with gas still in the bottle. I bet I can easily do a 11-11.5 hit since that's the next step up with the higher propane pressure. Then perhaps even more? The minimax allows me the time needed to apply the nitrous without overloading. Love this thing!

Is it crazy that this kart has made over 20 bhp with 17+ of that nitrous on a 46cc air-cooled? I couldn't even control it very well at all with the uneven tires in the drive axle. I toned it down to about 17-18 bhp in total (estimated)... it's FAST!!! And reliable!!! It's also how laughingly slow it is on N/A power with this tall gearing, yet it pulls nasty on the gas! Can't get enough of the lovely nectar! :yes:

I'll post updates whenever I can. Sorry no video this time. :blackeye:

I went out today for a bit of a sunday drive and had a play with the spray... I hadnt used my nitrous for a few weeks, due to the cold weather, and mainly using my car for shortish journeys, where its not worth turning the bottle on and warming it up... so you kinda get used to a certain amount of power...

boy I had forgotten about how instant the power is with nitrous :twisted: :lol:

Another win for nitrous! Unlike having a full-time power adder, you tend to FORGET what the thrill of the added power feels like after a time and it is as if feeling it for the first time all over again! Think about it, by now you'd probably be numb to the sensation of a turbo or super by now and would be aching for more, which ends up being a constant chase for that unicorn feeling!

Anyway, here are the updated pics and don't freak over the generic solenoid, I just re-purposed it and I'm well aware of the risks associated with it. If I had another Pulsoid to spare, I would use it instead.

The generic bottle and solenoid is used for water injection to cool the piston and it is REQUIRED for this unmodified 2 stroke, or else the piston would seize up. This engine is completely STOCK to the bone and has withstood 16-17+ HP worth of nitrous with more to go! It is really hard to keep the kart straight with this power since my tires are uneven in the back, but it does pull hard!
Also notice that I'm using a Crossfire to direct the N/F mix directly into the engine, simply 'fogging' the air box was no longer working correctly; I wanted to use two Venom injectors but this was what I had on hand and it JUST makes it far enough to get close to the center of the bore, while leaving room for the water spray to enter the carb as well.

:yes:
