Stock 2000 miata with FM setup from Manifold back.
2.5 exhaust with cat. Fab9 vibrant 'stage 1' intercooler. Running stock timing map from brain's basemap.
Turbo is a SR20 modified to a '2560'. FM manifold was modified with a tial EWG (by thirdgen).

-Make sure boost cut was set up for 12 psi
-Disconnect wg line
-Do a 4th gear pull starting at ~2k rpm

Started at TPS of 3.2, psi -12.2 and 1687 rpm.

0 PSI : 1771 RPM at TPS 38.3
1 PSI : 1886 RPM at TPS 100 (first reading at 100 TPS)
2 PSI : 2105 RPM
3 PSI : 2174 RPM
4 PSI : 2370 RPM
5 PSI : 2551 RPM
6 PSI : 2742 RPM
7 PSI : 2883 RPM
8 PSI : 3005 RPM
9 PSI : 3102 RPM
10 PSI : 3200 RPM
11 PSI : 3253 RPM
12 PSI : 3349 RPM
/Boost cut @ 12

Should I do this again and start when holding the 'boost' at about atm pressure with the throttle? In any event, this doesn't seem too bad.

nice, good to hear.

very curious to know if you get the typical tq fall-off after say 5kRPM with that turbine housing and ex combo.

Engine: MZR 2.0L (factory stock 2009 NC)
Turbo: BW EFR6758 vband 0.85 A/R
Manifold: Gleason Manufacturing (Fab9 kit)
Downpipe Size/Style: 3" stainless vBand (Fab9 kit)
Exhaust Size: 3" stainless all the way back (Fab9 kit)
Exhaust Components: 3" Vibrant integrated metal cat in the midpipe + Vibrant single 3" vBand inlet / dual 2.5" outlet (Fab9 kit)
Intercooler Core Size: Treadstone 30"x9.25"x3.25" with end tanks (Fab9 kit)
Engine Management: Stock ECU + EcuTeK hybrid speed density tune for this particular run...
Other Spoolin' Helpers/Hurters: TurboSmart IWG75 dual-port actuator on a 7psi spring, 4-port MAC solenoid, eBoost2 at about 43% duty and WG pressure of 13.5psi

This was in FOURTH GEAR on a SIX SPEED transmission, but this was because the very first OE run on the dyno was also in 4th gear and I never caught it until it was too late. Wanted to be consistent in my later comparison runs... As such, I have some better spool waiting for me when I go back and have it retested on my own tune and in 5th gear as it should be.


2300RPM: 2psi
2550RPM: 3psi
2700RPM: 5psi
2900RPM: 7psi
3200RPM : 10psi
3400RPM: 12psi
3650RPM: 15psi
