Aibast Posted December 25, 2012 Report Share Posted December 25, 2012 hmm, so I would expect something like 70 - 75 out ot 620 J15 4 speed?. Where thinking about this with a friend of mine one day. Main thing, dould it do 90km/h -100km/h for 100km straigth? And what RPM would the engine be at?. I don't need to go fast in my datsun I have my R - for that (255km/h topspeed) Quote Link to comment
BlackCasio Posted December 25, 2012 Report Share Posted December 25, 2012 I hit 80 MPH in my '81 720 4x4. It's got a weber on it so its not completely stock, but rpm's were only at 3800 at 80 and the pedal wasn't to the floor yet. I want to do a full tune up before I push it too hard.

wayno Posted December 26, 2012 Report Share Posted December 26, 2012 Quite a long time ago when I had a R16 in my roadster, I pushed it to red line in 4th gear, it was all the car had, I figure it was doing 100 to 105mph which is what the top speed was supposed to be for that model. Later in the late 90s, I bought a 68 with a U20 in it and transferred the whole drive train over to the early 67, one day while driving over snoqualmie pass before Cle elum on flat ground, as this mini van and me had been 90+ as we seemed to be the only ones on the road, I decided to let the mini van know the reason they were ahead of me was that I didn't want the ticket, so I passed them like they were standing still to show them of course, that is when I thought the world was coming to an end, every piece of dirt in that car went airborne, it got in my eyes and I was having trouble seeing the road, I let off the pedal, and that mini van went by me like I was standing still, I thought I lost the transmission or driveline, the noise was horrific, at about 70/80mph all the noise went away, I gave it some gas pedal and everything seemed fine, I pulled over anyway looking for transmission fluid on the ground, but everything seemed fine, I had no idea what happened. A couple years later going really fast it did the same thing, this time I got under the car to see what was going on, as it turns out, the driveline near the tail of the transmission has this corrugated piece of rubber that is blowing up like a balloon at high speeds and hitting the tunnel sides, this whole car could have flew apart, as the driveline could have just as easily destroyed itself and or the transmission tail shaft, I got lucky twice, I have never went that fast since. It's probably better to leave the high speed stuff on a track, the ambulance is closer. There is also the fact that you can lose your license and go to jail these days, they are really negative about driving that fast anymore, the ones that get caught make the 11 oclock news. 1 Quote Link to comment

DISLEXICDIME Posted December 27, 2012 Report Share Posted December 27, 2012 135 in my 510 let off because the rear end was lifting and getting loose. My 720 will do 100 . But that is as far as I will push it Quote Link to comment
Jdm720 Posted December 27, 2012 Author Report Share Posted December 27, 2012 110 in the 720 before the tune-up, car-pool lane... Then things started getting bumpy.. Haven't gone past 90 in the past couple of months though, can't push crappy tires in this rainy weather Quote Link to comment
DAT510 Posted December 27, 2012 Report Share Posted December 27, 2012 Got my 190E up to 120, and I got the 510 to 65 today with the three speed Quote Link to comment
Jdm720 Posted December 27, 2012 Author Report Share Posted December 27, 2012 Got my 190E up to 120, and I got the 510 to 65 today with the three speed Once I was going 120-130ish around 3am in my 300E, and this newer Audi passed me.. Well kinda just flew by me... Must have been going at least 150+.. I let off the gas a little, and got off on my exit...... Quote Link to comment

I'm usually the fastest one on the freeway, and I mean that in the least douchebag way possible. Quote Link to comment
Jdm720 Posted December 27, 2012 Author Report Share Posted December 27, 2012 Lol I never see anyone speed anymore. I'm usually the fastest one on the freeway, and I mean that in the least douchebag way possible. I see people speeding all the time around here.. And I think, "damn assholes need to slow down..." But then again, I only think that when I'm cruising with traffic in the 720.. Any other car and I suppose I'm that asshole :rofl: Quote Link to comment
yankabilly Posted February 28, 2013 Report Share Posted February 28, 2013 95 on the hyw in my 85 king cab 5 speed z24 and 195/60/15.... Quote Link to comment
Scurrvy Posted February 28, 2013 Report Share Posted February 28, 2013 Well I think my speedo is off but by time I hit 5th gear it says I'm going 75, and it just goes up from there. But it has to be off because that's ridiculous. Quote Link to comment
Samuel Posted March 1, 2013 Report Share Posted March 1, 2013 78, only because I dont really care to push it any harder than I need to so far. Quote Link to comment
85720Bullet Posted March 11, 2013 Report Share Posted March 11, 2013 85 in my 720 and it was like being in a roller coaster...LOL Josh Quote Link to comment
wallaccx Posted March 11, 2013 Report Share Posted March 11, 2013 I did 70 in my '85 720 this weekend-- it was a loud ride thanks to the muffler, but the engine settled at 2750 rpms and seemed perfectly happy to do it. Oh, and I had two old-ass Vespas in the back, so she had a few hundred extra pounds to deal with. Quote Link to comment
_chiefjt Posted March 11, 2013 Report Share Posted March 11, 2013 Stock with a 38 weber in my '86 720 with no load. Not sure if spedo is correct but shouldn't be too off. ANYWAYS, I hit 95 fairly easy at 3500 rpms and it wanted to keep going. haha Quote Link to comment
NissanEgg Posted March 13, 2013 Report Share Posted March 13, 2013 I just did the speedo the other day in my 85 720 base model short cab/bed with the stock 3.70 gears. Had the needle touching the trip reset button and tach was showing about 4600ish rpms in 5th, about 110-113mph on I-85. New Weber 32/36, complete tune-up (timing, fuel filters, cap, rotor, plugs, wires, valve lash, oil and filter, trans and diff oils), Pacesetter 4-1 header with crappy fart can exhaust from the p.o. that terminates before the axle. The speedo died about an hour later, the teeth on the speedo pinion gear shredded off. :no: I think I had the speedo pegged on the trip reset button too long, about 3 minutes. Only backed off as the water temp slowly started creeping up a little above the middle. My old 91 SE-R, 141 mph on I-10 in Florida following an RSX Type S. My old 93 NX2000, 136 mph, bone stock, down hill. My old 92 Eclipse GS-X, 155 mph hitting rev limit in 5th, roll racing a turboed '00 Camaro SS. My old 91 Isuzu Impulse RS Turbo AWD, 132mph, hitting rev limiter in 5th gear on I-20 outside of Birmingham. Stupid short 4.31 final drive gearing, close ratio 5-speed, and rev limit is 7300 rpm. My daily 94 Sentra LE 5-speed with the GA16DE, 118 mph hitting the factory speed limiter. My 86 300ZX Turbo, with the factory 3.54 gears and '87 spec turbo trans (higher 5th ratio), hitting 125 mph and only about 3900 rpms. Fuel cut is 6700 rpm. Anything above 125 mph and the hood starts to flutter badly. The numbers add up around 187 mph at V-MAX with my gear combos, I don't have the balls to try. Quote Link to comment
metalmonkey47 Posted March 13, 2013 Report Share Posted March 13, 2013 Did 75 in my 620 the day I put the 5 speed in, and it was screaming. I hate the tall 4.37 rear end. Quote Link to comment
Yeti Posted March 13, 2013 Report Share Posted March 13, 2013 My z22 powered 4x4 720 will cruise noisily at 130 km/h if pushed, but I haven't gone above that. She's most comfortable around 100, and burns noticeably less fuel at 80-90. Definitely slows down for hills. I usually have my boat in the back and plenty of time to get to my destination when I'm in the 720. My speedo may be off given the bigger tires too. I got my 3rd gen maxima up to 210 km/h with more left to go before chickening out. She was lowered on tokico coilovers and 17" rims and was so smooth on the freeway that 150km/hr felt the same as 100. I really miss that car. Not so good on gas (could have been my driving style), but so comfortable and reliable. Had over 350 000km and still going strong when I got rid of her. Good old VG. Quote Link to comment
red76datsun Posted March 13, 2013 Report Share Posted March 13, 2013 did about 80 in my stock l20b with a 4 speed in my 620. flat ground. RPMs? let just say...... the little l20 was pumpin them out :thumbup: Quote Link to comment
Sick720 Posted April 10, 2013 Report Share Posted April 10, 2013 I have a 83 720, weber carb, stock manifold, pipe (with the stock cat) and a cherry bomb muffler. And i hit about 110, but without the cat it'll do 122 on a downhill, gotta hold it for a while though. XD Quote Link to comment
