Therealsandybang Posted February 19, 2015 Share Posted February 19, 2015 Took it to Unigroup. They reckon it may be the high flow metal cat I installed.

hypergear Posted February 19, 2015 Author Share Posted February 19, 2015 few bits to check on: 3inches or bigger Metal induction pipe with Pod filter. Check pressure drop across intercooler 3inches or larger turbo back exhaust, all flanges has to be in 3inches, Cat has to be in 100 cell, no cat gives the best result. Tension up the actuator rod. Further update. This is the ATR45 SAT version for RB26, I've trailed the ball bearing version, and it have made a very slight increase in response. I'm hitting the MAP limit for the Haltech ecu, will be installing an 3 bars maps sensor shortly. Result against Standard Bush bearing model: Also running against my factory twins: Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/533/#findComment-7483378 Share on other sites More sharing options...
Missileman Posted February 19, 2015 Share Posted February 19, 2015 (edited) Any decent tuner would have dropped the exhaust after the dump... its the first port of call after an unexpected result.

Therealsandybang Posted February 19, 2015 Share Posted February 19, 2015 (edited) He sure did drop the exhaust. The catco 3" metal high flow cat was brand new and installed by dvs. Hence why he dropped the muffler only. Jjr dump front pipe also 3" bell mouth brand new installed by him. Unigroup reckons even new cats can cause restrictions. We will see tomorrow I'll keep you all updated Edited February 19, 2015 by Therealsandybang Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/533/#findComment-7483384 Share on other sites More sharing options...
colourclassic Posted February 19, 2015 Share Posted February 19, 2015 Any decent 100cpsi cat is not going to cause that large a restriction. Maybe 5 or 10kw, not 50.

Therealsandybang Posted February 19, 2015 Share Posted February 19, 2015 (edited) That's what I said. But I have to go through the detective work with the tuners which is a costly and painful process Although they are both great to deal with.

AngryRB Posted February 19, 2015 Share Posted February 19, 2015 (edited) I seem to remember 2 threads where there was a low power output, one was the GTX3067 thread and other Hanaldo's thread, correct me if im wrong but I think both had return flow intercoolers and JJR dump pipes..

hyper-gear Posted February 19, 2015 Share Posted February 19, 2015 Some intercoolers restricts, and I've found that with my stock GTR cooler as well. I've posted few examples here, Do a log with boost sourced before the cooler and see if that matches the reading on the sheet.

GTX3067 results were with return flow cooler, but dump is custom 3". That was thought to be an issue, but changed with zero difference. I'm interested to see results of this investigation here.

Dose Pipe Sutututu Posted February 19, 2015 Share Posted February 19, 2015 Also how good does the adaptronic go compared to the likes of Vi-Pec/Link/Haltech ect in plug/play versions ofc. What can you do the Adaptronic for $$$'s wise with the sensors ill need and everything to just plug it in and set it up to go haha I personally have not used Vi-Pec but I can comment on the Haltech & Adaptronic. Haltech is more refined, has enough drivers to run full sequential injection & ignition where as the adaptronic is semi-sequential due to the lack of output, but Adaptronic has native serial input for most widebands and also direct flex sensor connection where as Haltech you will need to use an analog 0-5v input and if you want more inputs you'll need a pricy IO expansion box where as the adaptronic just pull off the cover and hook up additional sensors. Also adaptronic has a built-in 4 bar (43.5 max factoring in 1 bar atmospheric pressure) map sensor where as a Haltech has a 3bar (29psi max factoring in 1 bar atmospheric pressure). If it boils down to features and price, Adatropnic hands down. If it boils down to software refinement and out of the box driveability from day one I would go Haltech.

Ben C34 Posted February 19, 2015 Share Posted February 19, 2015 You dont need a Dyno to check for an intercooler restriction, its cheaper to but another boost gauge or just move the boost gauge pickup to ore intercooler and see what pressure reads.

Therealsandybang Posted February 20, 2015 Share Posted February 20, 2015 (edited) Gentlemen, Did decat test. Ran 235kw at 13psi with no det on Unigroup dyno which apparently reads a bit lower (that's another argument). Still losing boost from 17-->13psi. Tao recommended pre loading actuator. Checked bov for leaks and did a run with it blocked off. Bov is fine. They don't seem to think it's cooler yet. Still some sort of restriction which is opening gate and preventing boost from being held.

colourclassic Posted February 20, 2015 Share Posted February 20, 2015 Pull the circlip off the wastegate pin and check that there is about 5mm (half a hole) of preload. Start checking hose clamps and silicone joiners. I use a JJR return flow cooler and dump pipe, they are not the cause of your problems unless installed incorrectly. 1 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/533/#findComment-7483814 Share on other sites More sharing options...

Missileman Posted February 20, 2015 Share Posted February 20, 2015 Also check your recirculation valve is closing properly, take it off and lghtly lube the shaft and piston with a smidgen of moly grease. 1 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/533/#findComment-7483819 Share on other sites More sharing options...
AUSBen31T Posted February 20, 2015 Share Posted February 20, 2015 Hoping mine doesn't get same issues with the .63 rear, however should be easier to hold 20psi externally gated yeah?My cooler is 510x250x70 , tube and fin, which is worrying me a bit, however can't go any wider due to auto spoiler motors for the flip down lip on the 31. Could go to a 510x300x100 probably max.
