the whole purpose of this thread is The DiRTy Risking Dave head and cam coffee table chat?

if its not im leaving

It would seem that way.

Dave if you have time on your side, there is a flow bench and equipement locally that I can line up for you. Just need to make a cam selection or try a few of the spare cams we have and make a decision based on what works with the ports you have done or want to do.

cool! yes paul it bench racing at its best :)

i find bench racing the most cost effective and easiest on tyre wear and brakes.

Speaking of bench...Santa dropped a new flow bench into our workshop over the break...got to learn how to use it properly now.

jun 2.7L

hks t04z 0.81 on trust s/s manifold

436rwkw on 18psi (98 pump fuel)

451rwkw on 22psi (98 pump fuel)

spark issues on 22psi so didnt push to rpm limiter (backed off at 7500rpm or so), more to come very soon with new ignition setup

when you say spark issues u really mean the chamber was ignited before the spark plug fired hey brad :D

How are you guys finding the results from the flow bench testing correlating back into the real world power figures? Its just a few of you guys were talking how NA cam and head setups are completely different to turbo head and cam setups however your still deriving results using vacuum based flow assessment.

My entry:

GT-R R33 vspec

Standard Bottom End

Standard Head Gasket

Standard Head

Drop in Trust 272* cams + Gears

Trust T88 Set up

Apexi Drag Cooler

Greddy Plenum

440awkw / 1134Nm torque at the 4 wheels on 26psi running PUMP FUEL @ Dart Automotive (New Mainline Dyno)

Motor Is still going strong...But managed to destroy a Trust 6 speed Dogbox hhhmmmm.....

:P

  • 1 year later...

How does a combo like that go on the street, response and driveability wise (T88) ?

I'm pushing 330kw Atm and have turned into a bit of a power whore.. Lol

So im considering going the t88 route with one of the smaller rears, any advice ?

Cheers,

Mitch.

I'd like to know this also...

Anyone who's doing "RnD" want to weigh in?

    • 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.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
