bjhines Posted December 23, 2012 Share Posted December 23, 2012 I have pegged the 160mph speedo repeatedly. That just means I am WAYYY off on speedo gearing. I dunno what the Camaro had for a rear end?, but that and the tires sizes are way off. Quote Link to comment Share on other sites More sharing options...
stony Posted December 24, 2012 Share Posted December 24, 2012 The only speed i have recorded is 147MPH. that was at about 8000 rpm. i have redlined it before so im guessing 155+ Quote Link to comment Share on other sites More sharing options...
rsicard Posted December 25, 2012 Share Posted December 25, 2012 "183 according to Garmin GPS on an straight empty road" with a T56 transmission in 5th gear, seems 200+mph is within reach with appropriate aero modifications ala NASCAR who are up to 200 mph on oval tracks. The T56 has a 6th gear (2nd overdrive ratio top gear). Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted December 25, 2012 Share Posted December 25, 2012 126mph in the 1/4-mile at Alabama International Dragway. Please be careful, my friends-what if a deer (especially one of the red-nosed variety) ran in front of you while you are rolling along at 147-183mph? I'd hate to lose one of you. Save it for the track. Quote Link to comment Share on other sites More sharing options...

Mikelly Posted December 25, 2012 Share Posted December 25, 2012 Yea, I turned a radiator into a "U" shape at Summit Point Raceway when I struck a groundhog at over 135mph in the Porsche Turbo. About $5K worth of damage. Mike Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 25, 2012 Share Posted December 25, 2012 Don't worry, in Groundhog Day you knew he was there and altered your line to let him live another day, and you went back to the boarding house to drink scotch and watch Jeopardy until you got the rest of the day right as well!

rayaapp2 Posted December 25, 2012 Share Posted December 25, 2012 The only speed i have recorded is 147MPH. that was at about 8000 rpm. i have redlined it before so im guessing 155+ That's funny Stony, What gears are you using. Im guessing I had a whopping 310 HP at the wheels in my 260Z using 3.70 gears, stock rb25 transmission, and confirmed with a Garmin GPS 147MPH resetting the garmins top speed in 5th gear somewhere not near redline. The stock gauge pulls over past 160mph and just kind of floats down there as if to say "Im to tired for this crap". I have been faster than 147mph in that car, but without the GPS there is no telling exactly how fast. I do know that somewhere above 147mph I loose steering wheel feedback slightly and every little gust of wind or bump in the road has a huge effect on the cars stability. Its not like any of the local tracks I can go to will see speeds higher than that though. Id be surprised at least. The new engine setup and wheels might just propel me there though.

BLOZ UP Posted February 8, 2013 Share Posted February 8, 2013 (edited) ~485 MPH, ground speed, with some turbulence. Edited February 8, 2013 by BLOZ UP Quote Link to comment Share on other sites More sharing options...
yellowoctupus Posted February 12, 2013 Share Posted February 12, 2013 (edited) Wow, That's moving. I'd love to see that video. Must have been a huge amount of pressure on that hatch to pop it open, and frankly I'm surprised the sudden change didn't upset the car. Doesn't take a ton to pop the hatch, especially if it's not latched all the way. I've found you'll pop the hatch at 90-100. All your stuff inside the car flys all over the place though. Not recommended! Edited February 12, 2013 by yellowoctupus Quote Link to comment Share on other sites More sharing options...
