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?

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
