admS15 Posted December 3, 2015 Share Posted December 3, 2015 is that int. or ext. gate? Also just wanted to point out that you should probably make sure you have the right details of the date and which turbo you are testing on the run id of the graph. It will be confusing for people in future when they are looking at results throughout this thread and you are talking about 1 particular turbo but the run id lists another.

Both results are internally gated on P98 fuel: R34 GTT RB25DET NEO unopened engine. - Adaptronic ECU- 1000CC ID injectors- Factory cams, cams gears, and all manifolds.- HyperGear ATR43SS2 Internal gated RB25 bolton Turbocharger- JJR 3 inches turbo back exhaust with bleeder valve.- Walbro 470L/H Fuel pump- 4 inches induction pipe- Split fire coil packs- PWR 600x300x81mm intercooler- Tuned by Trent Hewitson, Chequered Tuning.

Dose Pipe Sutututu Posted December 3, 2015 Share Posted December 3, 2015 I have seen 430+ a few times on the factory manifold with the gate off the housing. Welding it off the manifold could work well if you can get in and die grind it afterwards. I doubt you will see much in the way of gains between them. No need for stabilizer with pump e85, I have been on Caltex/United e85 for 6 odd years without running a stabilizer and never cleaned my filters or injectors. Watch your timing, I much prefer more boost and less timing as you previously mentioned Johnny. I tried a mixture of things, first few runs pushed the SS2 (circa 2013) to 26psi, but it bled down to about 23psi.. no real difference in power, then tried a few more runs each time less boost. Seemed pretty happy at 23~24psi however no difference in power. This is when I started adding in more timing, kept on adding more and more and more to the point where it stopped making power (however was listening for audible knock, which I couldn't hear nor see on the logs). Pretty much ended up with the following below (timing trace through logs vs. boost).

hypergear Posted December 3, 2015 Author Share Posted December 3, 2015 It could be the tires used. If its threading on the rollers it will under read. Does it feel stronger on road with the additional timing in?

Does it feel stronger on road with the additional timing in? I initially ran the car on the dyno and it made 290kW so I got my mate and the shop owner to hop in the back and it read 310kW, after that I strapped the car down fairly tight. I am thinking there's a restriction on the hotside/exhaust as I am running a very quiet exhaust system + a cat. I don't think it's timing related, as you can see I'm running a bucket load of timing (even the shop owner was like you're leaning too much on the timing to make power). However one thing to note, the car was running E61 as I only decided that morning to fine tune the timing map, so potentially the power shortfall could have been through diluted concentration of ethanol. After the new year, I'll put a new manifold on from HAVOC and see what the car can make before the motor grenades itself hahahaha Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/564/#findComment-7647866 Share on other sites More sharing options...
hypergear Posted December 3, 2015 Author Share Posted December 3, 2015 Put ATR45SAT on it when its going to Havoc, and max that out. I've remembering reading a discussion about few members whom are chasing my results. First of all Trent definitely does not deliberately tune a dangerous amount of timing to boost up results, he tunes it no different to any other cars. Turbocharger is nothing but a hot dryer without effective supporting mods, I will pin point few that have made a noticeable difference to my own car as some of you already seen. 1. At 3 inches metal induction pipe with a good pod filter Differences VS stock: 2.Good front mount intercooler: 3. Big exhaust or add an exhaust Tee: Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/564/#findComment-7647965 Share on other sites More sharing options...

No 45SAT I'm happy with the lag of the SS2, anymore and I might as well just have a dyno queen that's absolutely useless for the track. A little more power would be great and maybe more response.. I do like the looks of the new SS2, would be perfect for track use. 4k worth of rpm to use!

hypergear Posted December 3, 2015 Author Share Posted December 3, 2015 There has been quite few upgrades to SS2 since your one was built. When sending the manifold to Havoc, send your turbo down in I will have a look to see what updates can be applied to the existing housings.

Havoc has my manifold already, but I haven't taken off the turbo yet as I still need the car for an upcoming track day. Note that I will need a new rear housing as discussed as I'm currently running a scotty mod housing Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/564/#findComment-7648121 Share on other sites More sharing options...

I can confirm the lag on the 45 is quite high (posted my dyno graph in here somewhere earlier). I don't mind it but then again, it's not a track car. Maybe one day I'll get sick of it and go SS2 or something of the sorts.

I don't think your RPM vs. KM/h has been derived properly thus it looks a little more laggy than it is... Also should go E85 ASAP, with the added exhaust gas produced, you'll get the turbo on noise quicker.. look at the result posted here: http://www.sau.com.au/forums/topic/55845-rb25-turbo-upgrade-all-dyno-results/page-53#entry7637416 It's all in at 4500rpm and makes a silly 365kW Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/564/#findComment-7648155 Share on other sites More sharing options...
hypergear Posted December 4, 2015 Author Share Posted December 4, 2015 Is this right Stao, or am I reading it wrong? Depending on the turbo is working with. That reading is out of an ATR45SAT model. Yes it have made a big difference with exhaust ventilation, its almost as driving with no exhaust at WOT. On a Rb25det Neo motor the ATR45SAT's making 20psi by 4000RPM, check to see if VCT is active, preload the actuator by an extra 2mms and see if that makes any differences. 1 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/564/#findComment-7648209 Share on other sites More sharing options...
