Bolt on NOS on ebay--anyone tried?

[akskoot]

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.

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.
