Guest bastaad525 Posted August 13, 2003 Share Posted August 13, 2003 yeah the ZX's are more aerodynamic and should hit higher top speeds. Kinda sux... you think they're bigger and bulkier but they are still SLEEKER... heh. Quote Link to comment Share on other sites More sharing options...
scottyMIz Posted August 13, 2003 Share Posted August 13, 2003 145mph on the speedo with the windows down the car was all oevr the road very scary and prolly wouldn't do it again.I wasn't at redline and it was still pulling(this was last year racing that camaro ss)I did it down a flat road that no one travels but it's just way to dangerous for me to do it again.

V8ZRACER260Z Posted August 20, 2003 Share Posted August 20, 2003 I had my stock speedo burried at 160+ with one of Florida's finest in the rear view. Well, he was in the rear view long enough to see him turn on the lights. I'll see what it will do after the modifications are done in a safer environment like the Silver State Classic.

ZR8ED Posted August 26, 2003 Share Posted August 26, 2003 Well since I'm depressed a bit about my engine woes, I'll wallow in the past.... I hit a calculated 147mph in 5th gear@7400rpm. 2.9L N/A 280 with serious engine mods, and moderate aero mods ie car lowered to 2.5" off the ground, front belly pan, one side mirror, no antenea or marker lights, mild rear flare, smoothed out front end, Calc's were based on RPM, wheel dia, tranny and diff ratios etc... The Z felt pretty solid, as I waved out the window as I passed the Ferrari I was racing with at 135mph! Quote Link to comment Share on other sites More sharing options...
mobythevan Posted August 26, 2003 Share Posted August 26, 2003 You talk about a brick, I did 110mph in my 68 chevy van(see avatar). I've only had my 240z to 110mph so far, it felt much much better than the van. Quote Link to comment Share on other sites More sharing options...
Guest szlash280z Posted August 26, 2003 Share Posted August 26, 2003 one would hope the Z feels better than a Van! Quote Link to comment Share on other sites More sharing options...
jvanen Posted August 31, 2003 Share Posted August 31, 2003 I had my stock 81 ZXT with an automatic wound up to 7500 and still pulling hard......poor mustang couldn't keep up. Of course your engine lets out a nice scream when you go past 7G on the Tach . That was on 215 65/r15 Potenza rubber to so go punch it into your transmission calc.

GrayZee Posted August 31, 2003 Share Posted August 31, 2003 He had a nice photo of himself driving down the autobahn @ 160+mph in a 240z with what he said was a stock turbo engine. Oh, the photo was taken as he was doing this speed, 1 hand on the wheel, the other on the camera. My buddy has a Viper and he did the same thing. (one hand on the wheel, one on the camera) He took a pic of the speedo reading 320kph!! Quote Link to comment Share on other sites More sharing options...
Guest yatsen Posted August 31, 2003 Share Posted August 31, 2003 A little off topic: A former colleague of mine actually made this rather interesting pic while cruising on his bike in Germany: Quote Link to comment Share on other sites More sharing options...
Guest szlash280z Posted August 31, 2003 Share Posted August 31, 2003 that pic seems to be too stable to be running that fast. I got my speedo to go 0-150 in 2 seconds when my car was on jackstands! Quote Link to comment Share on other sites More sharing options...
tannji Posted August 31, 2003 Share Posted August 31, 2003 he didnt say that pic was taken on the road, just that his friend took it while on the bike tannji Quote Link to comment Share on other sites More sharing options...
jvanen Posted July 23, 2004 Share Posted July 23, 2004 stock (as far as I know) 81zxt auto 215/60 at 7800 rpms 2am one night... turbo sure does like the high end but the engine lets out a whole new scream at those revs. Poor BMW 5 series didn't want to hang at those speeds either Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted July 23, 2004 Share Posted July 23, 2004 how are you guys not melting parts on stock (stock as in unintercooled) turbo motors pulling to 7500+ rpm??? Even at stock boost levels I have a hard time seeing the stock motor running at that RPM for very long (seconds....) Quote Link to comment Share on other sites More sharing options...
Tony D Posted July 23, 2004 Share Posted July 23, 2004 ooo key, the worlds only top-end turboed 280 with a 7800 rpm stock engine has weighed in...... The photo on the autobahn was my screensaver for about three years until that computer terminally crashed. It was actually 145 indicated, with proper sized tires, and a stock non-intercooled L28ET (eurospec) at 10psi boost in a 240Z The ZisiZit Super-Z went something like 178mph with a 280 body. I do not believe he had a G-Nose. This is the guy who (yes F-n-F Fans) blew the WELDS on his manifold. Apparently he was running 25psi, and sheetmetal a bit thinner than what he should've, and during the run on long course BLEW the manifold apart! So now that you guys have a boost figure, and a body configuration, and know what JeffP makes around 23psi... Can you figure how much HP it takes to get a Stock Bodied Z over 150mph? I'm with John C on this one. Anything over 150 TRUE is a difficult feat to accomplish. And it AIN'T happenin' in NUTHIN Stock Datsun 6-Style!

Scottie-GNZ Posted July 23, 2004 Share Posted July 23, 2004 stock (as far as I know) 81zxt auto 215/60 at 7800 rpms 2am one night... turbo sure does like the high end but the engine lets out a whole new scream at those revs. It was either screaming for mercy or stuck in 1st gear and I am sure those were its last words. OTOH......oh heck, BS! man, this stuff is getting thick around here so why not add to it. 135mph in a tick over 10-secs, pinned to the seat and still in 3rd with OD to go. Oh wait, I do not have a Z :D Quote Link to comment Share on other sites More sharing options...
johnc Posted July 23, 2004 Share Posted July 23, 2004 stock (as far as I know) 81zxt auto 215/60 at 7800 rpms 2am one night I'm with Scottie - BS story. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted July 23, 2004 Share Posted July 23, 2004 ZX's don't even have a tach that goes to 7800rpm... I did some G-tech runs 2 nights ago, and the car felt good at 120mph. It sure had a lot of 'go' left when I let off there! Ran a 13.83 on the G-tech with 9psi boost. (I blew up my walbro pump and am back to the stocker, hence the limited boost) The brakes felt much scarier at 120mph than driving the car straight did though.
