if you want your stock turbo to last you then 10 psi is all good, more than that starts to get unsafe, although i have heard of peoples stock turbo lasting ages on 14 psi :)

but yeah, 10 psi is safe, i wouldnt go more than that :laugh:

12 psi is a good one to have with dual stage

i use it and dont see the ecu going rich and retarded like it did on 14psi !!!

so 12's orite, if you really want perfection checks the afrs, tune, safc, etc but really just for drags yeah man 12's just fine if u running 7 psi everyday

p.s any more tho asking for trouble without a bigger front mount and basic mods

What about with a stock exhaust BUT with a R34 SMIC, what boost?

7psi....as I have been kindly directed by members of this forum :verymad:

Its no good for your turbo to be trying to blow through a tiny pipe that has a few 90 degree bends.

What happens when you blow through a small straw a lot harder than normal??........ Your face goes red and heats up.......so does your turbo :thumbsup:

but when i put the R34 SMIC it went to 8psi automatically, so surely 1psi more cant hurt it can it?...Im no expert tho, so any thoughts would be appreciated.

Are you sure your boost went up when you put the smic on? or was it the BC that you put on.

I did this same mod to my car, and boost didn't go up.

I'm no expert either, but it doesn't take an expert to tell you that your performance gains will be minimal until you do your exhaust.

Sure you can bump the boost up a bit, you'll definitely feel it pick up better down low, but overall performance won't increase by much, along with you putting unnecessary strain on the turbo.

yea was before i got boost control & still had std dual stage bleed 5/7psi...as soon as i out on SMIC i noticed it hitting 5psi alot earlier & also went to just under 8psi instead of 7psi

yea down low is awesome now & i agree without an exhaust not much gain in power is to be had especially in higher revs but just want to know whats a safe boost til i get an exhaust and power fc later on

As I said when I had a full exhaust and pod filter 10psi was fine had no dramas with it whatsoever. I wouldnt go any higher than that on the stock cooler though as there not very good at scrubbing the heat especially as we are getting into the hotter period of the year. I would leave your boost as is till you get an exhaust.

      Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?

      Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened.

      Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging.

      Infiniti Q60 Navigation Update

      By Chocolate Cheesecake. · Posted

      I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
