Get a 3071 to spool faster?

[dollarsignbill]

These charts are also posted in my build thread but was wondering if other people are seeing similar time/rpm ranges to get their 3071's to full boost (currently 18.5 target for me).

Taking me till about 4,700 RPMS, which is longer than i expected. I know we are spoiled with the quick spool of the k04 from the factory, but if it takes 4,400 RPMs to get the 3071 up, how long/what RPMs do the 3076 take?

It does feel pretty damn good once it gets there though.

[anavrinIV]

there's a whole thread on turbo spool times. But yours is super slow. You should be spooling it 1k rpm sooner.

I cant see attachtment, but should be quicker. This is a VD from a different guys thread with a gtx3071.

uhm manifolds...proper intake setup and supporting mods--intake--tip--reworked/ported intake and exhaust mafolds or aftermarket...overbore pistons and or higher compression pistons...headwork....

proper tune---alternate fueling---e85---more timing---meth--nitrous to spool. proper exhaust...downpipe--catback--turboback

if you let it breathe better...more air in and more air out....am i missing anything?

[dollarsignbill]

Thanks i'll read through the spooling threads and see if i can find anything different about the setup.

Would the AWD account for some of it? I noticed this last chart is a speed3.

Thanks, was looking for tips or insight on how to increase with my current setup...

I'm pretty sure AWD puts more load on the engine which will cause it to make more boost faster, if anything.

who's your tuner and what fuel? you are in the midwest. corn is readily avail.

also a mod list will help a ton with your question. yes here to help and not to be smart!

Spring preload. Problem fixed, send me your money. Or a boost leak. Or a preturbo exhaust leak

When you say spring preload you mean i should increase the spring pressure on the Ewg? Leak tests are a good idea. Havent' done that yet. No obvious leaks though.

Yes you need to leak test. Also if you're say using a 10psi spring in the ewg...you're gonna have slow spool.

Mazdaspeed CAI
CP-e BT inlet
CP-e FMIC
ATP GTX3071R bolt on kit
CP-e LRT Mani
CP-e Downpipe
Tial 44mm EWG
Grimspeed EBCS
Fabbed 44mm dump tube

Got tuned at DB performance in Rodgers MN. Yes corn is readily available around here. Just wasn't ready to make the switch. Sounds like that is the next move but i'm gonna wanna play around with this first. Moving to New York at the end of the summer so didn't want to switch to E85 tune.

get a tuner here to look over everything. @rfinkle2; @Justin@Freektune; @ms3blackmica; @Lex; @RichieRichness; to name a few. if everything mechanical is in order then it's probably just the tune.

Thanks. I'll double check everything mechanical this weekend and see if one of these guys can take a look. Can i just send my .ptm file to them for a look?

Im at 14.5 right now

[speed_freak91]

OP is running the CPE turbo kit I believe. So better flow mod's shouldnt be any issue.

Get a tune from a tuner on here and you will be good. That set up should have no problem hitting 22 psi by 3500 RPM. Hell Im hitting 22 on my 3076 at 3500rpm

Who do you recommend? Anyone particular for this setup. I might consider that. But also a little light on cash having just finished this and paid for dyno tune.

Any of the etuners on here. Im self tuning now, but I did have an awesome tune by freektune. But any of the other guys can fix you up just as well.

Just out of curiosity, what numbers did your dyno tune net you? Edit: never mind, got the pic to load.

Post up a 4th gear WOT log and I'll be able to let you know!

Thanks. Will find a nice straight open road and get posted. I'll do the boost leak tests first though

Perfect.

Mention me when you post it up, would you?

Fool don't you know there is no way you could provide a better tune than someone who is there with the car to diagnose any mechanical issues (which obviously didn't happen) @Mr Duckface Badass;

Lolololololololol

Increase vvt and lower timing for improved spool.

VVT is a good theory but doubt it's the cause of such a late spool. Something else is def at play. @86AmishMs3; also got me wondering what spring you are running.

[Vader]

He stated 14.5 (1 bar) spring.

Read noob!

[snailD]

keep in mind unless there is sufficient load put onto the dyno, it will spool slower than on the street. a buddy i tuned with a 3071 sent me logs from the dyno and was spooling 20psi at 3600rpm on the street and not until 4700rpm on the dyno. keep in mind the altitude of 4500ft isn't helping his spool time (stock manifolds)

[torquemaniac]

Didnt know the spring pressure of the wastegate could affect spool time...will this be an issue also with a 3port EBCS???

[RichieRichness]

Yeah man, a WG will crack open and bleed boost if the spring pressure to too soft and if WGDC targets are too low. However, this doesn't appear to be the issue since spring pressure is 1 bar.

Damn...I got a 8psi external wastegate for my build...I was sure that the WG would be remain closed during spoolup with a 3port EBCS (interupt mode) and the proper WGDC tuning
