Yeah, that's pretty slow for a GTR with GT2530s... But I guess he was only running 1.2 bar boost... New clutch and 1.6 bar and hopefully he'll break 120mph...

Your a hard ba$tard merli... jeeees I'd be rapt with anything that started with an 11...

Even at 17psi.. a street car that doesn't stress pulling easy an 11 is pretty impressive to me anyway. I know guys eg: with sti's MY03 pushing 22+psi with motecs exhausts etc etc.. and their lucky to see below mid 12's, stressing the crap out of their cars :rofl: oh well, the day will come and they'll realise I was right & they were wrong, "Save your cash & buy a GTR"

hahahahhahaa...

Well an 11 is an excellent time, well done.

The reason why I was so surprised/crest-fallen/upset in hearing that it only managed 116mph was because I'm going for the smaller GT-SS turbos on mine, and I want a 10 out of the thing. Granted, I'll be using nitrous as well, a whole second is quite a lot to make up for with nitrous.

Hmmmm...

116mph does seem slow for a 1/4 mile... but im not expert - you got the 11 sec figure so its all good :rofl:

I have been trying a few G-tech runs to try to figure out how to launch/shift with my car...

Best was 12.4@191kms/h (119mph)... but that was an average launch with wheel spin and a bit of clutch slip... (hence why i still need more practice launching)... (this was with a passenger and 3/4 tank of fuel)

I'm hoping to get into the 11's - i'll be happy if i can....

Well done markr34gtr! I haven't been out to willowbank for ages, last time I was out there you were just into the 12's. I might have to have a chat with you when my newly aquired GTR finally gets complied (been 5 weeks in the workshop!), get some tuning tips.

the reason the mph was low was i got there at 7.30 pm late from work did one run straight away when heat soak had already set in.. as we all no..

first run ran crap... so we changed the plugs to shrouded type plugs...

second run did 12.1 at 117mph but hit the rev limiter in 1st gear.. bugger....

third run did the 11.99 straight after the second run... engine still hot..

fourth run sprayed a little water on the cooler first had about 10mins break then

ran the 11.96 at 116mph..

merli just remember r34 gtrs are geared differnt to 32 and 33gtrs and are quite a bit heavier... not many r34 gtrs have done 10sec passes yet and this is why....

when i get my twin plate clutch and have say 22psi boost i am sure a 11.6 and 120mph plus run is well within this cars reach....

anyhow i am happy thats the main thing...

cheers....

Sorry Mark and others, I honestly didn't mean to be hard up on you... An 11 is an excellent effort, and especially considering your imperfect runs, heat soak (I can't believe you got so many runs in!!! We're lucky to get one run an hour at WSID) and low boost setting.

I'm just starting to doubt whether my turbo choice will allow me to break into the 10s, and these results just didn't fill me with confidence, that's all :(

no worries merli.... mate hks 2530;s are the only choice for all round driving and top end...

makes power from 4000rpm to 8200rpm...peak power at 6600rpm or so....

to be honest not many gtrs with 2530s even pull 10 sec pass.

gtss turbos will be good for track times not really drag strip....just what i have read....

we have now got a good set of spark plugs to run higher boost... the denso iridiums were not happy at 17psi...dont know why just didnt like it even with 0.7gap....

cheers...

Mark what rwkws are you running?? Don't wanna be a hero or anything but my best time so far is 12.09 @ 114mph (1.85 60ft), thats with standard turbos and standard ecu with 235 rwkws...

Just installed a Nismo fuel pressure reg and got it dynoed last week and got 259 rwkws...

I'm hoping to break an eleven tomorrow night at calder with this setup....

Good result anyway, with more practise, better clutch and more boost you should get a mid 11 comfortably...

Merli, your gonna be pushing s@#t up hill to break a ten with GTSS's, but if your going the whole hog (forged bottom end) its possible!!!

Cheers

about 280rwks at 17psi.... need 20 to 22psi and she will do mid 11s all day...

but single plate clutch is getting very smelly, oops...

280 rwkws, well then thats a really good result then, with better clutch and more boost, u should see low 300 rwkws and mid 11....

GREAT EFFORT!!!! Keep at it....

Cheers

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
