The stupid thing is, my 60foot time was 2.4 (which is crap, but getting better its usually around 2.5) and my quickest terminal speed was 104.5mph so thats up as well... I just cant seem to get from 0-400 any quicker today than 14.18 *shrug* I give up. Should just buy a GTR and be done with it.

Ok, my best terminal speed was 104.52mph that run was:

60' 3.003 sec (wheelspin, didnt grab too well)

330' 6.899 sec

660' 9.943 sec

1000' 12.516 sec

ET 14.680 sec @ 104.52mph

funnily enough I ran a 14.698 with a terminal speed of 89.82mph, 60' time of 2.561, so I'm beginning to wonder if terminal speed really means diddly squat. My best 60' time was 2.422 that run:

60' 2.422 sec (bit of wheelspin)

330' 6.234 sec

660' 9.322 sec

1000' 11.945

ET 14.158 @ 102.27mph

All my launches were done at 2000-2500 revs and dropping the clutch, I think I had about 1/2 throttle on but I cant remember, everytime I bogged down or wheelspun. I know my pineapples are lose cos they have been making ratteling noises, the workshop wouldnt over-tighten them so they've come loose again. Next time I am gonna insist they overtighten them. But my problem lies in the fact I cant get the car to hookup right with no wheelspin or not bog down. I've got 225/50 dunlop sp9000's on the rear wth around 20psi in the back, the only thing I didnt do was a burnout, but I dont really think it would have helped. Any idea's guys cos I'm getting pissed off spending $30 and not getting the times the car is capable of.

rob - i got my best results with a 3000rpm launch - but it did bog down a bit..

hmm me confused.. the car sounds like it should do alot better.. do you need to work on your gear changes? hows the 1st-2nd change? you can loose quite a bit of momentum if that change isn't quick...

My gear changes are good, its the launch that is letting me down I feel. I was only there for 30 minutes cos the missus rang me and apparently my mother in law was a bit upset I wasnt going to be there for lunch, so at 12:30 I sped back home. There was **** all people there, so I reckon its the best time to go, in 30 minutes I got 5 runs, thats better than any wednesday night session and it takes 2-3 hrs to get that many runs.

Yeah, have it balanced on the friction point, and just use the handbrake to stop you moving forward. Then when the last orange is about to go, drop the hand brake and the car will ease off the line, no wheelspin or axle tramp.

See'ya:burnout:

Gavs GTR did 12.6 with 277rwhp. Did yor boost stay up?could

try Turbo Viagra. Street meets have the start beams moved back

1.6m to look after the race line so your doing about 2.0s and

13.7-8s on the real 1/4 1.6m at the start is heaps.

1.6m at the start is the same as 1.6m at the end, and would make bugger all difference to the 1/4 time.

At 104mph, or 46m/sec, 1.6m extra track would add an extra 0.035s .... which at 14.18s would give you 14.14s quarter mile.

:uh-huh:

    • Sag as in the windows start to slowly open themselves, or they're just slow to go up/down with engine off?
    • It looks like it needs a big worm gear drive on it to control the rotating, not a few sloppy pins!
    • As Duncan said, first there was OBD, which few cars used, then came OBD2.   Now an interesting point, OBD2 isn't even for what you want to do. OBD2 is for emissions testing. There is some sensor data on OBD2, but it's up to the manufacturer what they're putting on it. Most scan tools operate on UDS, which like OBD2 is a standard built on-top of CAN. UDS specifies how to structure a message, what very limited things mean such as "read memory address" but it does not specify what is stored in which memory address, that is all up to the manufacturer. You either a scan tool compatible with that vehicle, or to know how to reverse engineer all the data, which can take a VERY long time and a lot of vehicles to get it right. Oh and then the manufacturer does a firmware update and changes what's where... Ask me how I know that as fact Oh, and by the time you've got the scan tool that supports all the manufacturers stuff, well, you're back at "But a consult cable and the Nissan software" The main difference being most manufacturers software these days works with the same hardware readers, as the readers are built to support J2534 which is another standard for how the PC communicates with the tool to make it do specific things on the car...
    • Rotisserie is fully assembled apart from centre connector which obviously isn't required until the car is on it. It packs away fairly neatly and doesn't take up too much room. (Now that I actually have some room after my clean up!) Overall very happy with the quality of it.  Assembly was a piece of piss.  The only thing I didn't like was that the pins that lock the rotation lock wheels in place were a bit of a dick in a bucket scenario. It allowed the arms to rotate a significant amount even when locked in place.  To fix that i measured up the hole and went and grabbed a couple of 18mm fully threaded bolts and a thread tap to suit. I ran the tap through top and bottom so it was threaded both ends.  Then just threaded the bolt through both sides.  It has made a massive difference which hopefully you can tell in the before and after video how much difference it made. 20250207_161431.mp4   20250207_161431.mp4 Hopefully back working on the car over the next few weeks.   20250207_162801.mp4
    • I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.
