BillZ260 Posted March 21, 2012 Share Posted March 21, 2012 In the Z, I only went as fast as I felt I had control, couldn't have been much over 100. Steering got progressively softer and I was drifting across the highway and shut it down. Quote Link to comment Share on other sites More sharing options...
Bornsy Posted May 16, 2012 Share Posted May 16, 2012 With the complete stock 76' 280z I have gotten the car to reach 135 Mph before it started popping, it needs 5th. For those of you with v8's only reaching that speed may want to reconsider how they build their engines. Quote Link to comment Share on other sites More sharing options...
78zstyle Posted May 23, 2012 Share Posted May 23, 2012 137 (according to the speedometer)vs a mustang GT. Not a v-8 though, with my l28et. I don't think I could of gone much faster. Quote Link to comment Share on other sites More sharing options...
tecreatta Posted May 23, 2012 Share Posted May 23, 2012 (edited) I've hit 130 mph in my 1979 280zx out on Highway 6 outside college station. Stock rear r180 3.7 gearing with new factory suspension. 3.0 NA L28. Car would have done more but I just about soiled my pants. I had to test out that new engine. In the 98 B4C Camaro 150 mph is fastest I've been. Edited May 23, 2012 by tecreatta Quote Link to comment Share on other sites More sharing options...
Zinger Posted July 14, 2012 Share Posted July 14, 2012 145 on an interstate. Tried racing one of those brand new camaro ss' I lost. :'( I kept pulling on him till 135 then he started pulling away from me. 6500 in 3rd gear when I redline at 6k? Decided not to push it. Really stable. But after I came down and drive normally I noticed I've developed a NASTY rear end squeak. I honestly have no idea what it is. I was recently talking to somebody and they mentioned a corvette servo for the 700r4 that would help out with the whole 'stay in 3rd gear forever' problem I'm having.

Mikelly Posted July 18, 2012 Share Posted July 18, 2012 We got traqmate data at the last event and with the car's ignition breaking down above 5K, I was hitting 131mph on the front straight at Summit Point. With that extra 1500-1800 clean RPM and the front dropped another inch, I think the car will push 145mph on Summit. Closer to 155 on VIR... Without verifiable data, I don't know how this thread is worth anything. Mike Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted July 18, 2012 Share Posted July 18, 2012 110MPH, I think. GPS speedo decided to record a max of 500 MPH (the default, for some reason). Looking at the logs, apparently I hit 110 MPH. Didn't feel that fast. Ignition breaks up at around 5k though. Was just trying to tune my car. That laptop steering wheel mount really comes in handy.

kaito Posted August 22, 2012 Share Posted August 22, 2012 Between 124 and 144. I maxed out 4th and was well into 5th when i gave up the race. I only had a lap belt. I was racing a g35 and I was glued to his bumper till I gave up. We were swerving through traffic like crazy at night. It was intense. The car felt SOLID. 3.54 final drive with 78 5 speed. Ive never felt so connected to the z as I did that night... Its alwasy felt sloppy till then. Ive done t3 coilovers and camber plates with 1 degree positive camber and no sway bars hooked up. 225 springs in front 250 in back. Im sure if I hooked up the sway bars it would be even tighter. Also energy bushings all round. Quote Link to comment Share on other sites More sharing options...

For those of you with v8's only reaching that speed may want to reconsider how they build their engines. You obviously haven't read this thread in any details. With a S30 the issue isn't horsepower, its aero. Quote Link to comment Share on other sites More sharing options...

Mikelly Posted November 25, 2012 Share Posted November 25, 2012 John, Keep keeping them honest, man!!! GPS Verified is the only data I believe these days. Way way back I had a buddy who was a cop who would shoot my car with his stalker radar gun. He was CLEARLY off or lying to me. Mike Quote Link to comment Share on other sites More sharing options...

John Scott Posted November 27, 2012 Share Posted November 27, 2012 (edited) Autometer Sport Comp Tach reading 5700 in 4th gear (.7), still pulling but red traffic light coming up fast. Vette 700R4 locked converter with my old Procharged set up. 225 50 16 tires (24.75" ?) , 3.55 gears. Had MSA lowering springs, 205 50 16 fronts, slight nose down stance. Felt really good, but wouldn't recommend. What ever it was that day was my fastest. You do the math..

I had it rebuilt 7 yrs ago and it has gone down the track many, many a times. It's funny how people say you cannot make a 700r4 live, bull! I have probably 50-70 9 to 10 second passes on that not to mention how many low-mid 6 second 1/8th mile passes. My head would spin at all the street passes I have made too....LOL Not sure if you remember me, I went by Zfan then but somehow my membership got jacked after I stayed away too long!

jnjdragracing Posted November 29, 2012 Share Posted November 29, 2012 In August we went a 8.67@ 158.53mph in the 1/4 with a stock R200. I hope to break the 160 zone the next time out. Quote Link to comment Share on other sites More sharing options...

JustAFantaZ Posted December 20, 2012 Share Posted December 20, 2012 (edited) 183 according to Garmin GPS on an straight empty road, no traffic at all n the middle of the night. The hatch flew open so I let off. 3.54:1 gears, 235-60/15 ET Streets, T-56 5th gear. There is a video. Edit: I'm sorry. I didn't realize this topic was in the Gen I & II section.

Disregard 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.
