Still waiting on those dyno sheets of a 1.6 spooling a 30r at 4k

At how much psi is this dyno ?

psi doesn't matter, just augments power band in boost.

He posted that to illustrate the later boost onset.

3076 is too different from 3071. If you dyno a wrong laggy setup maybe you have problems with 3076.

i haven't reason to tell lies. I didn't tell that i have full boost at 4000 i tell that i have very good spool from 4000.

I will post my dyno when i did it and then we can discuss about the power and spool.

I can understand that 1.6 is a european version smaller and strange to you.


Spool is depended from too many other things like compression, ic and tubes, exhaust, external wg etc etc

ps: My car is for drag street use not for trackdays, I have too many good results with my small 1.6 against to many bigger enemys.

well here's a GT3071 on a stroked 2.0L miata:

http://robinorobino.smugmug.com/phot...2_JYGEt-XL.jpg


2.0 forged bottom end
99 head with STOCK valvetrain (except for high rev. springs)
stock cams w/adj cam gears (i believe the intake cam is retarded at -2/-3 degrees)
Garrett 3071

22 psi on 93 octane
11.7 a/f
7750 rpm, making a nice broad powerband that just carries through the very end.

the red one here is another 2.0L Stroked miata:

Hydra ECU & the GT3071R turbo running 17 PSI.

Post your spark/fuel maps, datalogs, and your dyno chart. Not calling absolute BS, but I've driven a 1.6 with a .86 2860RS and it didn't get full boost until well past 4k.

He's not at full boost by 4000.

platinum 11-12-2009 04:11 PM

my gt3071 has A/R 0.50 to compressor and turbine 0.63

housing same with gt2560

I know that 2860rs has very bad spool and very older design than gt30 series.

FWIW...

I am in the process of finishing a long term 1.6 project. Damn 3 year divorce and car being in her name has put a damper on project. Title in my name and moving forward finally!

Here are some details....

3071 with .63 turbine and 4" inlet
BEGI cast manifold with Tial 38mm
3" all the way with wastegate tube running about 20" before entering exhaust, custom job by Corky.

Shitload of head work: +1mm valves, Supertechs strongest double springs & Ti retainers. Full port rework flowing 285 cfm at .400 lift. 274 duration intake & 266 exhaust with .395 lift. Chrysler 300m coils with M&W Pro 12 CDI

ACT pro lite flywheel with an SPEC stage 3+ Aluminum PP that has been modified for more torque holding power. MSM 6 Speed & Rear end 3.63 gears.

I dont expect this to spool till at least 4500rpm due to the agressive cams

jtothawhat 11-22-2009 12:19 PM

^^^ pictures? The 3071 sucks anyways...3076 is the way to go.

platinum 11-22-2009 02:06 PM

Sweet...but I think you should plumb up your turbo and wastegate before you head off to the dyno...

platinum 11-22-2009 02:14 PM

man this photo is before one week and was taken during the proccess.

buffon01 11-22-2009 02:40 PM
