300Kw Unopened 25 Club...

Also

20psi with an x35 should make a hell of a lot more than 390rwhp

[Ben C34]

That ffp must be really helping!

GTX35 is an awesome turbo but it only belongs on an RB25 with 2bar of boost

^^ This, otherwise you went too large on your turbo.

It's capable of 430kw at least, hanging off a factory manifold with a gutfull of ethanol...

mate of mine makes 400rwkw on p98 and 17psi with one on his 4l falcon

[Blackkers]

that's gotta be close to the max of the compressor

Yes there is either a problem with the wastegate or the rear houseing is not a good match for the turbo. Not worried about it for now bit over it gor now. Was advised by so called people on here to go with .82 rear. Wishing I stuck to my guns and put a .63 on it. Leaving it like this till I bolt my forged 3lt bottom end together. I agreed it should be making more power. Will be changing tuners thats for sure.

.63 is pointless on a gtx35

hell its pointless on a gtx3071

[joeyjoejoejuniorshabadoo]

.63 is rediculously small on a 35.

On the 3lt the .82 will be perfect

[Ben C34]

Was that an external gate? What spring?

[Blackkers]

0.63 on a GTX35 is a bit stupid. might as well go GTX3076 0.82 and make the same power less boost less lag

[lcxu105]

15psi spring and exturnal wastegate.

^^^ Told him to stick with the GTX3071R but didn't listen!

Picked up the GTX35R for a good price so couldn't turn it down.

Told him not to go .63 he DID listen but still insists on using the .63 even after the entire internets has agreed with me lol.

The 3071 woulda smacked that all over ball park mate and it'd be on song 2000+rpm earlier!

Lead a horse to water......

[lcxu105]

Only grabbed the 35 as im building a 30 bottom end. Otherwise yes would of stayed with the 3071. The 35r should be able to make full boost by 45 to 4700rpm. That I could live with on a 25 bottom end. This is just ridiculous at 6000rpm. Something is not right.Currently doing investigation to find out why. First thing I'm looking at is the wastegate then I will be having the turbo inspected to see if any problems with it. There is no gas leaks I can see or hear.

[jet_r31]

Thats a low 9 sec turbo on e85 in a lc with a 3.0bottom and auto

with a bigger housing.

dont blame the tuner..its highly obvious that your problems are elsewhere... The tuners job is to tune what comes in..its the person who put it togethers problem.

If its auto then id take a gtx3582 over a gtx3071 anyday

people have to remember it aint in a manual r33/34...

massive difference..

cheers

Found the problem. Roll pin in v band had partly fallen out. This alooud an exhaust leak in an area where it was unable to find. Bugger. Now when I fix it I will need a retune. Just hoing to fit a screamer pipe instead of plumb back as I think this might be part of the problem too putting extra presure on the clamp.

[Ben C34]

That's good you found it.

Did you have a bit of flex pipe between the waste gate and returning back to the exhaust?

[jet_r31]

Sweet..put 35psi in it now ..lol..

f**k of the plumb back crap...otherwise it will just cause you

to wonder where your powers going at a later date when you turn it up..

Cheers

[joeyjoejoejuniorshabadoo]

Might as well give it 30+

You're building a 3.0 anyway

[Rolls]

Yeah dont be soft, give it boost until it pings, then pull it back 10%
