Was that on the BD4s dyno...my understanding is their brand of dyno read less then Dyno Dynamics so thats a great result.

But more then anyting, i want to know if your happy with how it drives on the street. You think it is too laggy or a nice compromise between mid to top and acceptable city driving????

good to compare graphs at 20 psi once you get them up ...

my run went from 22 but tapered down to 20 psi

have to get some of these hi po rb20s running down the quarter mile

Diff goes in this weekend, then hopefully next Friday night at Calder im going to give my car another run at 1.5bar...hoping i can get the 60ft down to 2.0 flat and pick the mph up from 113 to about 115-116.

Im hoping for about a 12.2-12.4 , but will be stoked with a 12.6 and no breakages. Actually i will be happy with a few runs in the high 12s with no breakages:)

My problem is having been playing with cars so much of late im behind with work and some courses so no spare time :)

I did some standign 1/2 mile stuff at an airport lat weekend, and with only 1bar up the old girl she placed 18th out of 95 odd cars, full or Turbo Porches, GT3s, GTRs, Ferraris. I was only 8 tenths slower then a Z-Tune :P:)

What type of dyno do BD4's use?

its amazing how much a good boost controller can effect spool, when we were tuning my car started off doing a run with the controller off and it made 12psi at 4300rpm, took a good 800rpm for boost to go from 3psi to 12psi... then we switched on the controller, did the relearn and it now gets 14psi at 4000, just shoots straight up. averaged a gain of about 40hp from 3k to 4.5k! and thats just a crappy old HKS evc 3.

If only SA had a running drag strip, who knows wtf bob jane is doing down here... :)

Apparently the City Dismantlers bloke went to purchase AIR then Bob Allrounder found out and pulled the pin (bad blood between the two). There was a little thread in SA regarding the speculation of what was going on. Apparently the city dismantlers dude is switching the direction of which the drag strip runs.. So your not running in to the sun as the afternoon approaches.

true.. im going to fiddle with the EBC.. if i can see any improvement ill get it back on a dyno

thats something they should of done a long time ago. would be even better if they could lengthen the run off to allow the fuelers etc to come back but seeing as there is roads either end of the track it doesnt seem likely.

Whooo silv

Ya getting it up there im gonna havta watch my time's you"ll probably knock me out my spot in the times section.

Gonna havta hurry up and get the new car finished .Compition its fun hey ,good luck :-)

cheers Peter

My apprentice ran 13.9 @ 98 in his R32 4 door. Stock standard running 13 psi boost. was 1.85 sixty footing on MT street radials. I wanted too see what it would do standard before it has nitrous fitted, new fuel pump & clutch. Might crack a 12 sec pass.

  • 1 month later...

boost creep unfortunatly due to the turbo had the ex housing modifyd goin to pull it off again in the near future and get some more work done to it see if it can be solved

mods are

hks pod

r34 gt-r injectors

z32 afr

power fc

walbro intank pump

sard fuel reg

3in dump to cat

3 3/4 cat bak

kkr 480 turbo

fmic

stock bottom end

no cams

no cam gears

Edited by japwpn

its not to bad to drive the rpm scale is correct

as for getting it onto boost sooner to be honest i was expecting boost much later than what its coming on at these turbos are rec for rb25 and from what ive seen they are getting them on at 5000 rpm there abouts so u would think that mine would come on much later i was very surprised

    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.
