Had a quick drive up the road straight on cal 4 2 bar of boost lol
I was braced for violence but there was very little, I was expecting all hell to brake loose but it didn't, the turbos I think are so big the boost comes in progressive and doesn't give that big hit and brake traction like my RS6 does
it doesn't feel slow by any means but I think what makes my RS6 and the other gtr feel so fast is the huge torque at low rpms
My vbox will be out in due coarse so I can see in real terms where it's at
I've never had an engine that revs like it once above 6k rpms it's like it almost instantly hits 8k plus
And the gear changes are like a sledgehammer, instant hard shifts like I've never experienced before
Quite surprised it's not that violent either, but then 4WD is rarely a commotion.
The times will prove it's super quick I'm sure.
Glad to hear you finally got it! The waiting is antagonising I know!

100-200 kph should tell all mate
maybe the boost curve is dialled in smooth, it's certainly not the sledgehammer I was expecting just from booting it a couple of times
But if it pulls the times then it's all good as it's very driveable as it is 👍

The duckbill isn’t mad enough.
I would want it programmed to be horizontal when stopped. How’s your love for it?
Well chuffed with the car just want some seat time and some times to see where it's at
I'm on the fence about spoiler or duckbil not sure which to put on yet, the aero motion is controlled by the syvecs but can I be arsed to piss about with it, not sure yet lol
Found out power is limited in lower gears for obvious reasons
and also I wasn't really taking much notice of the actual speed just a glance of speedometer needle position
i was to busy flapping trying to look at boost gauge and rpms and braceing myself 😂
Which bought me back to the last time I drove my other gtr after being in the rs6, 110 mph in the gtr is the same position as 40 mph in the RS6
I think I've had a divi moment and was going a tad faster than I realised, 8k in 3rd roughly and some way into fourth 😂 lol my other gtr is the same the speed is effortless Even at 1000 hp
rs6 Speedo
Gtr Speedo
Once this lockdown is over will get it on the strip with my vbox In and see where we're at

Hub dyno is never a true wheel hp figure ,at the end of the day they are a tuning tool ,but when people say especially in USA it makes 1000 whp it’s usually near to our flywheel figure,can’t remember the calculations now but i do remember when I had the r34 gtr which had a hub dyno printout it was a lot different to when I had the car checked on a rolling road,but there was nothing wrong with the map just figures differed

If the dynojet works out similar to the dynapack then 1326 whp dynoed at all 4 wheels will work out to about 1400 crank hp, but the guide I've been told is 0.85 which would then be 1560 crank hp.
The times will tell the story though mate that's for sure
Yeah deffo agree,and as said should easily do 8s with that power pal
It is odd it didn't pull an 8 with wilfy, his best on 18" drag radials was 9.7 @ 161 mph, I'd imagine 161 mph terminal should be enough for a high 8 shouldn't it ?
It's gonna need setting up at pod with ethanol in and drag radials on and launch control set up to suit
Tbh trapping 161mph He should be running an 8 something,unless he cant get it off the line,I’m sure jurgun or how ever you spell it used to run 8.3 or was it the svm car when it was like 1600hp ,one of them two

Yeah I think jurgen and the other 2 jm gtrs all ran around 8.3, all I can think is the launch control has not been set up yet for the perfect launch on drag radials
Launch control has been set up on the road r888s pump fuel, 3200 rpm, that's all I will use to start with pump fuel and r888s at pod 1-2 bar boost and see how it goes
Buy I'd imagine with those massive turbos for a blistering launch on ethanol and drag radials it will need 5000+ rpm launch setting up
3200 rpm seems low to me so will be interesting to see how it launches at pod first time out, all I've gotta do is rr off, manual mode, left foot hard on brake, full throttle should hit 3200 rpm then hold and bup,bup,bup then off the brake, and hopefully no bang oh dear 😂🤣 lol
If it’s making boost at the 3200 rpm static on launch you will be fine as remember your auto car so it’s more linear ,just depends really on lots of things ,track prep,your tyre pressures ,suspension settings boost off the launch etc etc all make a big difference to the 60ft,if you can crack the 60ft then your going to go fast
Maybe you should just do some 1/8 mile runs if it’s not busy look at the data and set the car that way,as there’s no point going balls out if your say doing 2.0 or 1.8 sec 60ft your never going to get your best time
if you knock two tenths off the 60ft and your run is good you can normally see 4 tenths better time as you cross the line

The problem is I have no control over adjusting LC unless I educate myself on my laptop and the syvecs how to do it
On the dyno plot it's making 310 lbft at 3200 rpm, but that's 4th under load, Il just try it first as is in road spec and see how it goes, I shall have zero mechanical sympathy just ignore it and keep it pinned 😁😁👍
Or for first few runs just floor it with no launch,either way will be fast I’m sure,or downloud the run and email the data to the tuner let him alter the launch and boost etc then upload it to ecu simple

That's a good point about flooring it first of all without launch, I tried that in my other one as box isn't built for drag racing and on my vbox pulled 10.7 144 mph 👍
First times are in done one pull on v power max boost, no launch just rolling start 2nd gear but watching boost gauge doesn't seem to hit and hold 2 bar, I saw 1.6 bar and gauge showed a peak of 1.9 bar
could be it only makes full boost higher in the gears and rpm range than when I was looking
100-200 kph 4.24 seconds
And 60-130 mph 4.85 seconds
My previous best was 4.28 100-200 and 5.02 60-130
So this is quickest I've ever been
tyre error warning flagged up so only did the one pull, but feels good and strong so far
One more 100 - 140 mph in 3.3 seconds 💪

That's pretty mega, nice one. Bet it's nice to actually get out in the car and test it properly.
Happy so far mate, I forgot to put it on race mode aswell so I think it will have been shifting to early, I kept doing that in my other one, wish I could default it to race mode lol
JM imports have just confirmed in race mode auto shift point is 100% higher rpm, so hopefully with Max rpm shifting it will dip into the 3s 100 - 200 kph on pump fuel
Also boost is reduced in 2nd gear to aid traction so that's why I was only seeing 1.6 ish bar of boost, traction felt good so there's the possibility it may be able to run the full 2 bar in second gear aswell
Ethanol adds another 250 hp so there's more to be had yet with race fuel, I'm guessing if it's been tuned to limit of grip on race fuel then it will be well within grip limits on pump fuel makes sense to me

100-200 kph 4.1 seconds is about all she has to give on pump fuel
boost is limited in lower gears which I was thinking about having altered but I suspect once ethanol is in it and it's making more power across the board it will then be getting upto the limit of grip anyway so gonna leave it as is
My fastest ever time so I'm happy, was hopeing to dip into the 3s but gonna need some ethanol for that
Gets a move on then lol. Is that 60-120mph? I see on the web page for your Sierra that did 60-100 2.77. What’s the skyline do 60-100 in. See how much faster it is

62-124 mph, 60-100 mph 2.4 seconds, but it is not running max power at those speeds, 100-140 mph is 3.3 seconds and that's full boost by then, to put it in perspective rod was pulling 100-140 mph in 4.55 seconds
So I'm only 0.4 seconds faster 60-100 mph, but I'm 1.2 seconds faster 100-140 mph
The car will take more power in 3rd gear definately, but it's been mapped to the limit on racefuel so I need to get some ethanol in it and try it
I know ethanol in my other gtr makes a huge difference everywhere, so if it's mapped to limit on pump fuel once ethanol is in will be to much power in lower gears potentially
You would dip in the 3s if you were brave enough with the launch control
Never mate not 100-200 kph she's right in the power before 60 mph
I need ecutek dongle before launching as needs recalibrating alot, I need to do it now as it's occasionally missing 4th gear at light cruise needs clutch relearn
I've been in contact with racecal today I'm going to put a laptop in with team viewer and there going to remove the boost limiting in lower gears, that's what's costing me low down
Have had no grip problems yet will take more I'm sure
I've pulled 100-150 mph in 4.5 seconds, but 0-100 mph on 7.3 seconds.
60-100 mph is 1 tenth quicker than my other gtr, but 100-150 mph is 1.2 seconds faster, theres loads more in the tank 0-100 mph I'm just not getting it yet, boost is well down looked to be below 1.5 bar what I could see, want it at 2 bar across the board
I've also found out pump and ethanol are completely different maps so I can max it out on pump and it won't affect the race fuel map
And I have 4 boost settings for pump so I can still raise it or shift it down across the board and can flick it up a notch on the move, that's why I can't feel much difference upto 100 mph whichever cal I'm on as it's not giving me full boost yet

Yeah I agree the 0-100 is shocking for the power obviously got no grunt in lower gears as you’ve said,finds it’s legs 100 onwards
Yes mate needs full beans mode 😁😁
0-60 without launch will always be shit as turbos are huge, but to only gain 1 tenth 60-100 mph with an extra 170 hp over my other gtr on race is just not right
Just gotta wait for ecutek now for clutch learn, get syvecs on my laptop and an ethernet to usb adaptor
I just can’t get my head round 1080 whp and them times,being 4wd etc ,I no they are heavy But that’s a lot of power ,I suppose you really need to see the difference once you have more boost in the lower gears,but I presume they’ve capped the boost to save the gearbox In the lower gears so you might have to compromise
