That plus I'd still like to see you test the BOV - I have even used a cellphone to do this in the past . Just find a quiet stretch of road tape a streamer or something in front of the BOV , tape your cellphone somewhere so it can video the bov exit , hit record then take off through first and second should be enough. Stop and review the recording. If streamer is flying as you accelerate - bov is leaking, and that is why you need so much boost to make the power you are making.

66 lbs/min @ 2.3 PR is potentially a reasonable target on E85 depending on the variables involved
the variables we aren’t armed with, but somehow you’ve convinced yourself that you are
does their dyno read high or does yours read low? Are you the greatest tuner who ever walked the planet, or maybe not quite as good as you think yourself to be?
some answers aren’t always so easy to discern an absolute truth of.

On a stockport at 16psi Pump Gas on a VERY conservative break-in tune, here's where I landed on a "heartbreaker" dyno. Rich AFRs, barely any timing.
Blue Line = 13psi.
Green Line = 16psi.
Gain of ~33hp on a stockport for +3psi.

You know it’s a bit more complicated than that, but should be able to top this or any other GTX3582 (on a 2010 turdblown manifold in this link) in several regards

but again, your personal experience isn’t necessarily the end all of all rotary engine results _

Dyno results mean nothing without real world data to verify/validate those results.

500rwhp or 600hp....should be in the 5.5s - 5.9s range. A G42 1200c on a BP in the UK on pump fuel recently ran a 5.5s 100-200kph with 600bhp claimed.
I'm with Gucci Bravo on this one. Happy to stand corrected if a real world result is posted.

This is my favorite type of discussion.
We just don't have enough information without asking Louie or the owner directly.
At the end of the day, dynos are just tools to measure progress.
We have all agreed that G-Series Turbine Efficiency has turned the market on it's head, in a good way.
The GTX3582R is actually now closer to a G30-900, and let's be honest, for anyone who did this test, we were disappointed in the response of the G35 Series on these cars.
I have a wicked G30-660 0.83 V-Band 2.1L Stroker AWP VW buddy on ECUMaster with Flex Fuel and the setup comes in so much later than expected, it's pretty baffling. When the power hits though, it's warp speed. Similar powerband to a 2JZ on a Precision 7675.
These turbos are "tested" by some, but understood by very few. This thread here has really broadened an excellent discussion on turbocharger sizing.
I'm excited to soon show to you guys a high compression, flex fuel, Bridgeport + Semi-PP setup built for response on a G42-1200 Compact with Anti-Surge DBW and Real Air Mass Measured ECU configuration. It will be a game changer for bringing Rotaries into the modern Motorsports full vehicle control era. We've got every imaginable sensor to pinpoint strengths and weaknesses, as we optimize small displacement, larger turbocharger setups.

Honest question here... it seems like you just live on these forums ****-talking with a superiority theory, but never provide anything concrete.

I'm happy to admit I'm a keyboard warrior at present, hopefully that will change over the next 18 months. But there are people that make a lot of claims and slag others that don't really share any actual logged data, links to quarter mile footage or even dyno sheets of stuff they have done. At least badrx7 shares what data he can, likewise Omar and Green brothers have actually shared real world results on here or other forums or their Facebook pages.

It’s not the same thing as bagging on about the power or how fast my personal car is and then not backing it up. I was only responding to the guy sort of doing so after he mentioned posting up real world results, and the only intent was to urge him to go to the dyno and put some substance to it. Again btw, and not with any intent of criticism or malice. Because I’ve been supportive of him when nobody else was responding if you go review the history. So it seems more like a misunderstanding, one of several.
I’m sitting on two torn apart cars and $30,000+ in new parts all relative to those things mentioned and more, but am buried at work having not been able to touch anything for the last 3 - 4 months. It’s set to be 110°F here today going on for the last several months now as well. Not to make excuses, and if you want to call them that ok then, that’s just what it is. None of which is in my favor, and quite frustrating.
Here’s the thing; not everything happens out in the openness of these threads and posts. I offer myself up against anyone on here for putting my money where my mouth is. Some of it is out here in the open where can can see it. I’ve offered up new turbos at my own expense and risk for people to test or try; with no takers btw. It doesn’t bother me to have some fendermonkey make such an assertion. Because unless you’re involved in the other things not seen, then you can’t know. There are some people on here who do know though.
I express my thoughts and opinions openly. There’s not any issue on my end with anyone else expressing their own too, whether they agree with me or not, whether it’s directed at me or not. If you’re looking for a hypocrite, you need to look somewhere else.

Guys got an issue with my g35-900 setup and would like some help.
i got a g35-900 1.06 ar with double turbosmart comp gate v wastegates with 10 psi springs.
I checked all my vacuums to the wastegates nothing pinched my wastegates work fine and I have boost creep. My tuner told me that the problem are the new g series are a bit agressive and always boost creep, did you have boost creep with the g35-900?

1) Ignition Timing could be causing the boost creep.
2) Excessive Fueling could be causing boost creep.
3) There's nothing wrong with a non-flat boost curve and it's safer on bearings to have more boost higher up vs. down low.
4) Boost duty can be added down low to flatten boost curve and eliminate creep.
Frankly, if a tuner is saying that's an issue, they probably shouldn't be touching the setup to begin with.
These turbos don't have that issue, no turbo does. Ask yourself what are possible mechanical causes of boost creep and you'll understand...
Here's a Small Streetport GTX3584RS from yesterday, similarly sized to your setup.
GTX3584RS with 1.01 A/R on Small Streetport (see torque fall) and Flex Fuel. Power is at 24psi and fuel pressure dropping on this run.

2) Redo wastegate plumbing and make sure you aren't using a Water Port on the wastegate where you mean to have it plumbed to air.
3) Nothing turbo related will cause creep. It's all external devices.
Reach out if you want me to diagnose it with you.

1) Test the MAC Solenoid to make sure it's wired where you think it is. Do this by having someone enable low to high and high to low side operation in the ECU and it'll snap the solenoid open and closed.

I'm not an expert.. but how well designed is the manifold? And what size are those WG's?
Could it not potentially be poor WG prioritization or undersized WG's causing them to be overwhelmed?
