Yes, very nice. You will definately need those with the heavy GTR.... What are you doing with the old ones? Might be suited to very light GTST....

my car might be closer than ive made out...got some nice brakes for the circuit car today too Stewie...How does 375mm 6 spot AP's grab ya.

did you take your medication today Jas?

With all those tight bends it will be interesting to see the pressure differential between your turbo (making the boost) and the plenum (pressure going into the head)
Im not knocking it dude, and I can easily see it is the only path for it, just interested in how it will affect the pressure.

Sorry, it's my engineering background nit picking.

If mine is anything to go by it wont affect pressure at all. I have some crazier bends than adrian owing to me wanting to do things a certain way and it certainly has no problems throwing up 500 plus ponies at the treads.

Once boost is made the whole system is under constant pressure so i fail to see how bends can have too much effect.

Are you saying that you have the same pressure at the turbo as at the plenum? and no pressue drop?

Having a big volume of air going through those pipes with bends or reducers does affect airflow.

Especially under boost.

Although, for this application it may not be so important, i.e. 10secs at full throttle.

Think of why restrictors, aka washers, are used to control airflow in turbo cars in plenty of classes of motorsport to slow down the airflow.

also think of things like match porting exhaust manifolds or intake manifolds/plenums instead of leaving the sizes different?

2 stroke exhausts with expansion chambers are another example?

Should I continue?

Anyway, as Adrian has pointed out already, the piping runs are dictated by the space available. It's quite clear that this is the case.

And when you run out of boost to throw in it you can always get a fist full of Maccas straws, connect them together, run them from a hole in the intake and blow into it from the drivers seat, i know you can build some pressure Adzy boy :laugh:

You would blow half of the Viet pro's out of their knickers, literally. Ha, pity you cost more, my bottom still hurts lol

BWAAAAHAHAHAHAHAHAHAHAHAHAHAHAHHA......<big breath in>....BWAAAHAHAAHAHAHAHAHAHAH!!!!!!!!!!

Had the radiator serviced and a new cap fitted. It was more blocked than I thought so it should be all good now. Mounted and wired up the 2 x Maradyne thermo fans using both the factory switch and a manual override so I can have them on even if the engine thinks they're not needed. Also wired up the low-oil pressure switch and light and the Tech Edge Wideband unit and display. The backlight on the display is really good and dead-easy to read. Very impressed.

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day  
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
    • Are you 100% sure this isn't tune related?
    • 140-150 across the board. At this point hoping the grounding harness fixes it. My grounds are all tied to the chassis and none to the battery. For SR and KA that’s never been a problem for me but had a few other guys here and Reddit who told me RB really like a very solid ground setup tied to the battery so going to try that next, I’m stumped if that doesn’t do it. Never had a car have spark and fuel and not fire off before. Only thing I can think is the spark is intermittent/weak because of grounds nothing else really makes sense at this point 
    • I am having close to the same issue. Can you help me with what wire you grounded to get your pump to trigger?
