Just wanted to know if the GReddy air diversion plate made for the GTR also fitted the GTS-t. In particular I'm talking about the BCNR33, obviosuly there are differences in the body, however I am not totally sure they extend to the radiator support panel. Can anyone help?

I think you will find they are model specific.

The BCNR33 panel (If anything like the ARC version) will bolt to the front of the radiator support panel then join to the top of the front grill on each side.

Well through my business I will try and do a dyno test with one on and off. I'm very keen to dispell and prove quite a few performance tuning myths

that will be greatful if could do that for us all..

very keen to find out the difference..

dyno run? i dont think they claim any power benefit. all they do is (possibly) direct more air through the radiator and aid in cooling slightly. plus neaten up the look of the engine bay a bit. that's it. dyno test will be a waste of your time.

Yes your right with performance gains, but I was thinking more of monitoring engine temperatures in a reproduceable environment (dyno fan and cruising speed), which is quite hard to do with a whizz down the street and looking at your temp gauge.

should have got one in a groub buy that bassy organised, mine should be arriving about now, and i kknew it didnt do power gains but it will help alot with the cooling which is just as important, and it covers up a big gap in the front which the panel makes it look alot neater

ben...

I was mainly sourcing info for a customer.

Had a look at your thread and wondering if you have a template to suit the R33 trust front bar?

There is the possibility that I can make these designs (or coat them) in carbon fibre for those interested?

Fact is air is lazy, it will always travel the path of least resistance. Any gaps above the radiator, and you will lose air through it. The diversion plates seal off all the gaps so the air coming in has nowhere to go but through the radiator, thus helping with cooling. No rice about it, they were designed to do a specific job and they do it well.

Fact is people will buy anything they think they can talk up to their mates or even worse actually think works to any measurable amount themselves.

Next u will be telling me neons streamline the air under your car?

Or that tubro zet meant for a N/A car you put in your intake pipe has take a whole second off you 1/4 mile??

Buy it if u think it looks nice, but you will notice no difference in water temps etc.

BTW there is no gap above the radiator, it is sealed by the rubber than runs along the top of its support, Nissan aint stupid

When you guys get them and test them i would love to be proven wrong, these are after all only my idle thoughts.

Peace

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • 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.
