And if you keep using them, aren't there some leaks ?

AngryRB Posted December 29, 2015 Share Posted December 29, 2015 Do those earl kits suit GT30 etc turbo's or only for stock replacement? and do they have the required restrictor or is the restrictor in the turbo already?

RBrennan25 Posted December 29, 2015 Share Posted December 29, 2015 Using stock bov, nothing wrong with the GTT one at this power lever (sub 300).Mine started to leak after around 6 months, mostly driven on low boost (284rwkw at 15psi) had to replace with a GFB plumb back and adjusted the spring tension to max. Made a massive difference. For a small amount of money I'd say its worth upgrading Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/570/#findComment-7659264 Share on other sites More sharing options...

kingtube69 Posted December 29, 2015 Share Posted December 29, 2015 (edited) delete BOV, done Sounds mad too and gets the bitches - HWP may or may not love it though --- Disregarding the legalities behind decat, Stao on your test cases did any of them have a cat converter? I would be interested to know how the exhaust tee compares/ed to the decat - I recall talking to Johnny and he mentioned 10kw gain just by going decat IIRC.

hypergear Posted December 29, 2015 Author Share Posted December 29, 2015 Water fitting on the ATR4xx turbochargers are in M18x1.5 same as OEM. To get full power from the ATR45SAT internally gated version. It needs to be either in a 4 inches exhaust or a 3 inches pipe with 2.5 inches tee off factory front pipe. Exhaust on and exhaust dropped makes a noticeable difference in power.

kingtube69 Posted December 30, 2015 Share Posted December 30, 2015 Hi All, Just an FYI that Stao and I came across - I tested having the boost controller hooked up between the compressor housing and the actuator and then the charge pipe and the actuator. It seems that having it on the charge pipe I can achieve greater levels of boost across the board. I.E couldn't make 1 bar in first or second gear now it makes this and peaks at 18psi in third and so on easier now. Quoting Stao's response after my test: This experiment means there is quite a bit of pressure drop across the cooler, so the high pressure side would be opening the gate earlier while the lower pressure side will be holding the gate shut for longer, hence the boost gain. This is a good result, you might want to mention that in corresponding threads. Hope this helps someone else with the same turbo (ATR45SAT on RB25) 1 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/570/#findComment-7659751 Share on other sites More sharing options...

hypergear Posted December 30, 2015 Author Share Posted December 30, 2015 It is best sourcing waste gate pressure after throttle body, that gets rid of the variations of cooler kit. 1 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/570/#findComment-7659769 Share on other sites More sharing options...
Dose Pipe Sutututu Posted December 30, 2015 Share Posted December 30, 2015 It is best sourcing waste gate pressure after throttle body, that gets rid of the variations of cooler kit. You mean after the intercooler but before the throttle body, ie cold side Taking pressure from the plenum to control either your internal or external gate will cause issues.

GTSBoy Posted December 30, 2015 Share Posted December 30, 2015 ^yuh, I'm with him. The only signal that should be taken from the plenum is for boost gauge or equivalent boost reading input to the controller. The actuation signal MUST come from pre TB.

Makes no differences on my truck cooler . Yep makes sense now I think of it. Most people run the blitz coolers (like mine) so i would hope it helps a lot of people. What cooler are you running? Pics or gtfo ------------- Charge pipe pre throttle body yielded the best results for me - Boost pressure is now about where I expect it to be but still suffering pressure dropping. I'll confirm by running the boost gauge pre cooler this weekend.

Dr. Surge Posted January 1, 2016 Share Posted January 1, 2016 Stao, is it possible to machine a internally gated turbine house for a td06-20g in 10cm? And how is a td 06 compared to a ss2 and op6 highflow in terms of power, torque and response ?
