islandborn Posted December 18, 2015 Share Posted December 18, 2015 Jackal, I'd be interested in it if you want to unload it after Brian is done with it. Hell, Id even foot part of the "rebuild" cost....or I'd buy it now and pay Brian directly.... Link to comment Share on other sites More sharing options...

I will consider this as your 'dibs' and to be honest, I can probably get the thing out to you (or Bryan, whatever would be preferred) within the next two weeks. My turbo is scheduled to arrive on Wednesday so I'm not exactly sure when I will get to swapping with the holidays but I can almost guarantee it will be well before New Year's (I'm waaaaay to antsy to sit on this for long). That being said, maybe we can discuss details of the transaction via PM if you definitely are interested.

fantasyxiv Posted December 23, 2015 Share Posted December 23, 2015 Out of curiosity I thought after stage two you have to start upgrading engine internals like pistons, rods, cam shafts ect? or is that sort of stuff needed once you are pushing for like much larger gains? Just asking because i've noticed how aftermarket TMIC's, fuel pumps, larger injectors are common upgrades as well turbos in some cases with a few of you guys. I'm just not that familiar with common modifications after stage 2 that's all. Link to comment Share on other sites More sharing options...
fahr_side Posted December 23, 2015 Share Posted December 23, 2015 We have several cars running at stage 3, on a stock block, daily driven at 300~335whp, with proper supporting mods and a solid tune of course. These cars are severely intercooling-limited, so anything that helps lower or limit charge temps will be a great help, especially using E85 fuel or meth injection. Otherwise, not much is needed beyond what you should already have at stage 2.

BBPeik Posted December 24, 2015 Share Posted December 24, 2015 fahr_side Is the scoop the main limiter? Any ways besides meth injection to cool down the charge? Thanks in advance My someday I will be done with it thread. Link to comment Share on other sites More sharing options...
FLlegacy Posted December 24, 2015 Share Posted December 24, 2015 fahr_side Is the scoop the main limiter? Any ways besides meth injection to cool down the charge? Thanks in advance Bigger intercooler, e85, fmic, intercooler sprayer....drive faster! I am thinking of me that injection at some point, with all the heat down here.

Ellesedil Posted December 24, 2015 Share Posted December 24, 2015 He's mentioned a few times that the scoop design is a limiting factor. It makes me hope that someone out there will end up offering front-mount solution by the time I'm ready to consider upgrading my intercooler.

BBPeik Posted December 24, 2015 Share Posted December 24, 2015 That or a custom hood with a bigger scoop. Hmmm interesting My someday I will be done with it thread. Link to comment Share on other sites More sharing options...
fahr_side Posted December 24, 2015 Share Posted December 24, 2015 The core is not tiny... it's certainly wider than that on the GH8 and SH9 models, but still I see heatsoaking faster on the LGT model. For sure the hoodscoop is a factor, it's almost half the height of the scoop on the WRX and Fozzies. If I install and tune for meth injection on a GH8 with an 18G I will most likely pick up 20~25whp from that. The same meth kit and turbo on a BR9 will pick up 30~35whp. Sure sounds cooler-limited to me.

jackal8788 Posted December 26, 2015 Author Share Posted December 26, 2015 Today the new (used) VF54 goes in so hopefully by tomorrow I can report back if the turbo was the issue or if 'The Boosted and the Beautiful' will be seeing another season. #fingerscrossed VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...
jackal8788 Posted December 26, 2015 Author Share Posted December 26, 2015 Well I just got off the phone with the guy who swapped the turbo and he said it is overboosting quite a bit. He thought it almost maxed my gauge out (30 PSI is the top). He just checked to make sure the wastegate is able to open fully and said it is opening fully though he cannot confirm what pressure it is opening at. I'm going to see if I can get a map from my tuner with a 0 WGDC so we can determine if the issue is related to the tune or something else. I'm really, really hoping this is just tune related and that he maybe had overly aggressive WGDC tables in this last map which led to the overboost. #fingersstillcrossed VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...
BBPeik Posted December 27, 2015 Share Posted December 27, 2015 What the hell Jackal. You cant catch a break. First its slow, then it is boost leaks, now it is overboosting. Are you sure you are not making this up just to keep us entertained and this thread going on forever. All kidding aside. I hope it is just the tune and that it all works out.

The builder was the one who drove it after the install. I am hoping this is something simple like a leaking signal line and/or the tune itself. I'm already kicking myself for saying it but it seems that diagnosing an overboost shouldn't be too difficult as there aren't many factors that can cause it. Now that I've made that idiotic statement, let the next round of troubleshooting commence Edited December 27, 2015 by jackal8788 VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...

jojorios Posted December 27, 2015 Share Posted December 27, 2015 Stupid question, but on the new vf54 has the wastegate been ported? That's exactly what I was thinking.

Perscitus Posted December 27, 2015 Share Posted December 27, 2015 Typically with a bigger turbo or a 3 port EBCS the tune would have lower WGDCs, but Ive seen strange cases where WGDC needed to be raised as high as 75-80%.

Could this be the creep many have been experiencing since your prior turbo was already ported? Not stupid at all - it's definitely a valid question. No, this is the stock WG with no additional porting or smoothing. I just drove the car myself and also took some datalogs. The issue is not with the tune. It is making ~24 PSI at 40% throttle and 3500-3800 RPMs with the WGDC at 1.57%. I will need to do some more checking on the signal lines for leaks and/or obstructions which are preventing the WG diaphragm from seeing the signal pressure. Stay tuned....

fahr_side Posted December 28, 2015 Share Posted December 28, 2015 (edited) Sounds to me like something isn't working right. You will usually see boost creep at higher revs, as the wastegate is no longer able to bypass enough gas past the turbine to keep shaft speed in check. I like the simple test of connecting the actuator straight to the compressor housing nipple with fresh vacuum hose, no pills or restrictions. What you're looking at is very much like what happens if you connect a 3-port up the wrong way.

I assume that once I have corrected the issue though, I would want to keep the restrictor pill in that branch of hose between the compressor housing and the tee that runs to the BCS and the wastegate actuator?
