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:

    • Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s. 
    • Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?
    • Hence why I said earlier that I don't think the turbo Neos ever would have actually qualified as an LEV. I suspect the only actual LEVs that came out of Nissan were the NA Neos. Still call them all Neos. They all stil have the Neo-ness. Just that they don't all qualify as as LEVs.
    • It will give gains, but you wont hit 600 It will give gains but it wont get you to 600 imo. You will also sacrifice low down and you will be adding extra volume if you port match it, more so if you port the plenum runners depending and how its done I think the only time youre going to see about 100hp gains is if the car is making well over 1k kw I do have a spare set that I was going to test with, but i dont actually think there is anything worth getting going larger. I did a fair few S14/S15 and the standard TB is fairly small, I went to 60 and in some cases 64mm which is significant over the stock unit. You can also get some weird ratio changes. I think 20kw will be a stretch on a roller dyno. If I had it apart I might mill the shafts a little and not expect much, I think the stock size is still pretty good for a street/track car even with larger capacity. I might change diameter it if its a drag only car
