has anyone tried the Sneaky Pete bolt on NOS kit? Sounds pretty rad for $35. If you can control your trigger finger doesn't seem like it'd roast the motor to me. Then again, I've never tried it. http://cgi.ebay.com/UNIVERSAL-NOS-KIT-S ... 5813617993

I see broken rods and cranks in someone's future.

Oh my gosh. That is amazing.

at that price someone needs to try this

Agreed....not it.

The eBay listing says they come with 16gram cartridge . How much N20 is that?

• In chemistry terms, 1 'mole' N20 (6.0 x 10^23 molecules) is 44 grams.
• 1 mole of gas at standard temperature and pressure (like 'room' temp) is 22.4 liters
• The eBay kit is (16grams/44 grams) * 22.4 liters, thus 8.1 liters, about 2 gallon milk jugs.
• A 50cc engine spinning at 8000 rpm displaces 400,000 cc/minute --> 400 liters of air/minute
• A single NOS cartridge discharged over a 1 minute period will give 8.1 liters/400 liters --> 2% concentration NO2. That sounds to little for fun.
• I have no idea the amount N20 guys use. Lets assume 8%, giving about 15 sec of boost per bottle.
• eBay has some 16gr N2O cartridges listed - 20 for $25. This is an expensive way to go.

Next - look at what an experienced racer is using. In the Builds section tru72 is building a drag bike. He has a 2.5 lb N20 tank (over 1100grams). Thus in a racing scenario, I'm concluding more N20 is used than our 8% assumption.

That really isnt the sneaky pete system but looks pretty cool. NOS Systems is the one that does sneaky pete and their cylinder is refillable but - this still looks like a good deal if you run your bike extra rich. I may do it at some point.
