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

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.

no VCT, I missed that bit...why ?

It's on. But on at 3200 off at 4k I think. Trent recons he would have it on possibly till like 5500.

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

Should be on just above idle ~1500 till ~5.5k

I work till 6 in malvern. I doubt ull hang back for me to have a quick Suss though. Too late at night?

Definitely. Any change in the car may change the tune so change it now to save some cash later

No problem, PM me.

you could drop the exhaust from the cat and do a run with an open exhaust to see if the cat is a restriction?

[ARTZ]

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?
