Sick question here...But,

[Paolo Castellano]

I would like to know what is the fastest anybody has HONESTLY gone in stock (.5) 6th gear with a 3.73 rear end gear ratio. This would of course be on a flat, straight highway, probably a silverstate or equivalent. I know the 3.73 generates a lot more heat(that's why they have diff. coolers). I punched in a 3.73 ratio on http://orbitdevelopment.com/vipergears/gears.asp and it shows 203 MPH @ 5,000 RPM(w/3.73 in .5 6th). I looked @ my dyno sheet and the HP/Torque #'s appear to be higher @ 5000 than @ 5900rpm where I have been before in 5th with the stock .74 and 3.07. I realize there is a certain drag limitation where you need a large amount of HP for every additional MPH, but I was just curious if anyone definitively knows if there is a chance of hitting 200+ in 6th w/3.73 or at least 193 or more that can be had from the stock car @5800RPM or so. Paolo.
Frank Parise, where are you????????????????????????

In a stock car you will never hit that speed of over 200. Did you reclaibrate the speedo when you changed gears? Most likely you lost speed at top end with the bigger gears. Too compensate the gear change you will need more HP too over come the 200 MPH barrier,

my car is not stock, I have headers/exhaust and put down 470 corrected RWHP and 507 corrected LBS/FT torque. I went slightly over 190 when the car was bone stock/ no K&N's or anything. Paolo
