Opinions On My Tune Gtx3076

[SRS13]

Great result mate. Congrats.

So it's hitting full boost by 4000rpm.

That's pretty damn good, especially when you are running the stock manifold and the gate off the turbine housing aren't you?

what size exhaust are you running?

Not sure on the road speed conversion to rpm but it seems to be hitting 16psi at 4000rpm; 16psi is the boost level chosen not 'full boost' capacity of the turbocharger and system. Don't mean to be picky but its good to know the difference as it can be misleading.

If it were to run more more boost, it would take more rpm to generate that additional boost. Basic eg, full boost could be theoretically 45psi + and at that boost level, it would not hit that at 4000rpm but more rather 5000rpm or so. More relevant, if they were to turn the boost up to 25psi, they might see that figure anywhere from 4200rpm to 4500rpm.

Glad to hear you got it sorted mate. great result!

Really makes me think about adding the juice to mine too. Be really interested to know what the higher compression would do with it.

How much would you estimate the additional costs were? do you have a ethanol meter? tuning etc?

yeah 20psi at 4000rpm and yes stock manifold and gate off the housing, i have a 3 1/2inch system and 3inch muffler ,

thanks mate, the juice had the tuner shaking his head laughing, he did the tune in about 45min which was pretty good going,

additional costs were

injectors and rail - $830

fuel reg- $270

modifying manifold -$50

others hoses,fitting ,fuel etc -$200

tune$200-$300

shit sounds like alot, best not thinking bout the total dont have an ethanol analyser, its been tuned on the richer side and im just going to keep an eye on the knock levels.

Im well aware of all this, but full boost to me usually refers to the maximum boost setting the owner has choosen to run for the supplied dyno graph. For the more novus reader though, i can understand where you are coming from.

I think 4000rpm is decent considering the flow capacity the gtx3076 has, I'd be stocked with the result. Wonder if the poncams made much of a difference?

i just looked one of the video's i took , its actually before 4000rpm, ill try to upload it to show proof of the road speed v's revs,

it looks like 100km/hr is about 3500rpm in 4th so if thats right then i have 20psi at about 3800ish

Good shit man! can't wait to get mine running on the stuff

[AngryRB]

heres a video from the tune.. and yes the rear bumper ill eventually get painted ..

Needs more boost for sure! Nice result though

[ARTZ]

sounds crazy...like a spaceship....

[AngryRB]

haha.. even when cruising its like a kettle whistling and whining , dont have need for the radio much these days lol

Haha nice result man! Gotta love that sound!

Your standard engine will take more boost and love it

[ARTZ]

yeah cant say I ever listen to my radio anymore either...

i would take it out but then there would be a hole in my dash...

[AngryRB]

how good is that HD clutch hey?? is holding alot of power .. i know it will eventually let go with some abuse at the drags but its not doing too bad at all

[R31 POWER]

Sweet result. Not taking to piss, but why do these turbos fall over to 16/17psi? My hks gt2835 pro s does the same???

cos of the internal wastegate

[AngryRB]

cos of the internal wastegate

Its an external wastegate, tial 44mm with a 0.82rear housing , i doubt it could ever fall over

It looks that way because of how the boost controller was set, i put in 90%duty up till 3500rpm to try and get it boosting early, and 60% for 3500-7000rpm

we never touched it on the dyno , just did a run and because the power was what i was after, decided to leave it where it was, there is no problem getting it too hold 20psi all the way thru if we wanted to, but this way the engine isnt being leaned on so hard toward the end of the revs, so a quick adjustment on the controller would see 350kw probably, but i dont want to be rebuilding an engine for a while yet so will just leave it for a while.

For ARTZ, I honestly think the external gate setup here helps with how impressive it is.

The internal gate would be a different story, a little lazier IMO.

Im pretty sure Mick_O is on par for spool with this car but has a GTX71, i dare say if he went external gate off the housing his spool would improve again.

the answer was for the hks pro s (r31 power)

I went for a nice drive in Mick O's GTX3071 R33 today and am so blown away at how good it is that I honestly cannot see how he could improve such a potent weapon. Running e85 and an incredibly fast spooling gtx pumping 330rwkw it had me laughing madly all the way and being the really nice bloke that he is, he was laughing as much too! Thanks so much Mick O, Ur setups just so amazing.
