very decent results with your car there mate.

I have a question and I guess it is more of a technical question though..

with all the talk of skyline turbo's and ceramic wheels dieing over x psi and so forth..

your's at 14psi and still going for god knows how long and according to the mag, more than 100 1/4 passes in that form..

common theory of the ceramic exhaust wheel breakage is too much boost which results in too high exhaust temps which break them.

so with the use of NO2, what effect if any does it have on the exhaust temps?

is this the reason for your turbo still living today?

also, is your NO2 disconnected in someway when outside WSID?

what sort of boost is dialed in during street driving?

thanks and all the best.

Exhaust temps actually go up with Nitrous Oxide usage. Boost spikes to 14psi on the bottle but only very briefly. Over-speeding of the turbine wheel can cause it to delaminate from the shaft - not always JUST heat related.

I don't drive around with the bottle in the car when I'm on the street and when I drive to the track it certainly isn't connected. Theorhetically I should also have the solenoids isolated with blanking jets but that sounds too much like hard work to me :D

Boost for street driving is usually your regulation 8-9psi with the EBC turned off. That's where it lives most all of the time. Off.

Thanks heaps guys, girls and pusseh boys like brett :)

      The downside of this is when you try to track the car, as soon as you hit ABS you get introduced to a unbled system. I want to avoid this. I do not want to bleed/flush/jack up the car twice just to bleed the f**kin car.

      But again, the engineers said your cast aluminium would be fine based on the load that would be stretching that section. Same load stretching the bolts in a flex (not the twist), with a much smaller cross sectional area than the original part you've broken. It's why you'd need to be using higher strength bolts, but that's just making up for the strength you lose with less area...

      I am truly amazed someone on this planet was able to cycle the pump using a scan tool. I've always ghetto cycled them on Nissan 90s shit boxes by slamming the brakes and pulling the handbrake to agitate the rear wheels enough to cause a speed difference

      I didn't actually try it at the time but a Launch X431 with the appropriate software licenses/upsell will have the ABS bleed function. The Consult II you can still find some old sets of equipment but they're really, really expensive:

      Well I'll start by saying I'm not an engineer. I am going to go with the KiwiCNC ones.  They are made of 7050 alloy have good fillets and radius.  The material alone is in the order of double the strength and fatigue resistance - Those bolts, once torqued correctly place most of the load at the flat face of the mating surface - the 'stretch' you're talking about through torqueing them up would be far more than the extra stretch 'load' placed on them from a steering input or bump. (in my opinion) so I doubt they would flinch.    - but again "not an engineer".      oh and I don't think stitch welding 7050 is a good idea, likely just weaken the material (from what I read)
