Had the GTR back at the drags last night got a personal best in before the radiator decided to pack it in went [email protected] with a 1.7 60ft. Car is currently making 270rwkw on unigroups dyno in Sydney .

My question is that to me the trap speed seems abit low for this power level specially after reading about other r32 GTR's with similiar power going 117mph plus though the top end ?.

r/t .549

60' 1.784

330' 5.077

660' 7.837

mph 91.48

1000' 10.138

ET 12.104

MPH 113.99

k/mh 183.45

Don't know the cars exact race weight at the time. It's a r32 GTR vspec N1 had about half a tank of fuel and rear plus passanger seats removed. The pass seemed pretty clean didn't miss any changes and shifted at about the right rpms. What do you guys reckon?.

Mate, honestly it sounds about right. If I didn't know ny better though, i'd say thsi post was a total gee up. :P

All jokes aside, if i was guessing what your trap speed probably should be, +/- 10% i'd have to say it's not too far off what i'd expect. I would prob have guessed about 115mph so that's not too bad. Well done for getting out there and racing though :cheers:

i have n1 turbos in my r33 gtr , stock injectors ( they are at their limit ) stock cooler , even stock airbox ,ebc and power f/c on 1.2 bar .

i have run 11.7 @120.85 mph , 1.846 60 ft but a lot of wheel spin in first and a little in second .

Yeh must not be much more left in it then, I soppose it's time to lean on these 2530's abit harder then. I'd love to know how these other GTR's with even less power then mine are trapping 117mph plus or maybe the owners are stretching the truth.

Hey wrxhoon hows things. Do you know what type of power you are making at the wheels?. Like I said before there are even a few examples of r32 GTR's on these forums with less power running in the high 11's at 117mph plus , one example would be HIRISK's old white r32 GTR which trapped 117mph with about 250rwkw. I'm alittle frustrated at the moment because everything else is fine I'm just lacking that little bit of top end to be able to reach my goal of an 11 sec pass.

was it you last wednesday at wsid ? i was there with another r33 gtr testing it .

i just noticed you have 2530"s ( i thought you had n1's ) .

i know of another r33 with 2530's he has about 275 kw and hid 12.1 @110 mph but 1.7 60 'in all his runs . we took it and had it retuned but never been at the drags again it will be intersting to see what he does now .

i dont know what power i have but at a guess 300 rkw min .

i wish i could get 1.7 60 ft , mine is not a vspec so that may be the reason for not geting traction .

Yep was me at WSID last wednesday white 32 GTR with black wheels. Yep I saw you guys there and I had a funny feeling it was you but wasn't 100%. After what you say about your mates r33 my figures seem pretty right now . Looks like I'll just have to lean on the turbo's more and come up with something closer to 300rwkw for some consistant 11sec passes .

i was there with another gtr , series 3 f33 , this one has gtrs's and i'm trying to sort it out , it has 340kw but could only do 12.4@113mph , the clutch was sliping if you launched hard .the last run we got a good launch 1.8 60 ft but missed 3rd gear, it did 12.4 but 110mph , that should have been 12-12.1 .

the other gtr with 2530's has been tuned since but hasnt been back at the drags , that should do high 11's now .

my car should do low -mid 11 's with 121 mph trap , when i took it there the track was very slippery though .

with a better tune and your 1.7 60 ft + lighter car you should do 11's every day .

if you want a good tune pm me and i'll tell you where to take it .

we are taking the series 3 there on monday , let you know how it goes when we go back to wsid .

i got a feeling that the n1 turbos are much better than a lot of people think they are .

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
