Hellloooo LADIES!
Good to see some familiar folks around here. Just had a particular question for the folks of DSMCentral and what they think. I now have a 2005 Yamaha Raptor 660 as my fun-toy of choice. I'm looking to install a wideband O2 setup to make tuning the carbs on this badboy super easy as it's becoming more and more common. Just wondering if the guru's here could tell me if there would be any difference between the widebands used on any regular automotive application and say an ATV? If there isn't any real difference, I'll be looking to pickup a used Innovate LM-1 for those that might be looking to sell -------------------- "I hear he tunes the space shuttle also...and that thing is fast"

QUOTE (93dsmowner @ May 7 2008, 06:20 AM) Yeah, so with a 200lb operator, you get a P/W ratio of 13.33 on the Raptor. To get the same thing (assuming about 3150+200 for car) you would need roughly 251 horsepower to the wheels (assuming Raptor is 45 to wheels...) I'm thinking stage 1 cam, ported head, and stock bore 11:1 piston before the year is over for a pump gas beast... giggity giggity I think the best part is it cost a fraction of what it would have cost me to do this to the Camaro or Talon. $150 for a cam, $120 for a piston, and about $200 for a professional port job. For under $500 it'll be a BEAST. I think the only thing that really costs a bunch in comparison is the exhaust for these things. A decent dual exhaust runs about $600 new and you can find the singles for around $350. -------------------- "I hear he tunes the space shuttle also...and that thing is fast"
