almost 1000rpm of spool difference, although completely different dyno setups so not really that compareable. Still it really does look like his is set up perfectly.

He is also using external gate and manifold, what are you using?

Internal gat and no manifold. I get full boost by about 4k on Trent's dyno. Forget the other chart. Ill post up Trent's one asap.

Gives me hopes to see the gtx spool faster than gt. Means ill have same/more top end with better spool.

4K actually sounds around about what I would have expected for that setup, thats not too bad.

Trent recons a bit of a fiddle n we can knock 500 Ish off. And give me another 20+ throughout midrange.

this is probably stupid but could t be the standard intercooler piping is also choking it..its only 60mm tube and that turbo is trying to push a large volume of air..also dont know what cat its running..still seems to me like its just choking up...im not convinced its just tune related :unsure:

Quite possibly but Trent recons mainly actuator based. I'm sure he would mention if it seemed to be choking at the cat or cooler. 3" highflowed cat.

Well he's got the advantage of having had it on his dyno and seeing where the potential is so thats pretty promising, I guess if VCT isn't (but can be) enabled there's definitely gains to be had just there. Sounds quite promising, and basically means GTX3076Rs will be full boost at ~3500rpm on RB25s which is pretty sweet.

Get rid of the cat.

How many people here that run this turbo are actually using a cat? or can say they have seen this turbo on a car with a cat? and are making a fair comparison on the response side of things. No cat will make a big difference

id be getting a 80mm hotpipe and at least 70mm cold pipe made up as well.. PM scottynm35 hes near dandenong and will make that up for you.. He can probably gut your cat as well..

And get all this done before it goes to avo Monday week?

its a 3 inch cat on a 600hp capable turbo, of course its a restriction..

infact his whole setup is a restriction ....no offense shifty ;)

No.its not. Lol. At 600hp yes. But 3" Turbo Back is enough at this power surely The cat Is highflowed to 3" too. So id assume thats ok. I have 4" intake. That's fine. What else is.there?

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
