Are you sure your injectors aren't going static and staying open at 18psi?

EDIT: Can you start a new thread so we dont clog this one?

myprojectB13 · 09-21-2004, 07:49 PM

Numbers seem pretty low for 18 pounds of boost.

I have a 60 trim T3/T04E w/ Stage 3 wheel & .82 back housing....
I made 270 @ 10 psi....
You made 273 @ 14.5 psi
As you can see...something is not up to par unless water injection hurts power like that

1F@$t9d7 · 09-21-2004, 09:08 PM

can you guys not see my A/F ratio. It is below 10:1 once I get it up to 12:1 it should pick up around 40hp. I know it seems low but the car spits fuel out the tail pipe.(not really but I bet it is close too)

hazar_SER: even on 15psi I was still under 10:1 on the A/F ratio. it is probably close to 9:1 but the wideband on the dyno only went down to 10:1

Your car is running lean also. If I had an A/F ratio like yours then I would have simular power

Well i dyno'd again today. 320whp@ 7500 and 270tq at 5700 at 15psi. the 336/287 was a boost spike ato 17.5psi. I was having a bad time with ignition misifes though up top. my only clean run is the run 21 in red. the 336 whp is at 6600rpm and i bet if that held, and i didn't missfire then it probobly would have put down 350ish whp at 7500...

RYAN_S-14 · 10-09-2004, 08:59 AM

here is my dyno runs and mod listing.

S-14 SR20DET, 850cc injectors, fuel pump, intake, q45 maf, type r bov, stock side mount intercoller, 3 inch turbo back. i think that all for now.

.7 bar (10 psi) of boost both runs (could not turn it up 1 bar like i wanted because i did not have the best gas in the car)

translated into american thanks to Daryl wife

Dyno Run #1

The Light Blue Number says "31.8" Thats my max ft lbs torque..just take that number and multiply times 7.23 so:
Max Torque - 229.14

My adjusted max Power is the Green Line it say "267.0PS" take that number and Multpliy by .9863 so:
MAX REAR WHEEL HP - 263.34

Dyno Run #2

The Light Blue Number says "32.8kgm" Thats my max ft lbs torque..just take that number and multiply times 7.23 so:
Max Torque - 237.14

My adjusted max Power is the Green Line it say "278.8PS" take that number and Multpliy by .9863 so:
MAX REAR WHEEL HP - 274.98

thats decent for me since i have the stock t-28 turbo and for the most part its on stock boost..

next mods in order, FMIC, cams, ras, headgasket

let me know what u think.

dam you guys sh*t on my readings

insane imports · 10-23-2004, 07:37 PM

I finally put some of my dyno charts, and time slips on my car domain page! Just click the link in my sig. and go to the last page. The mods are listed on the site. I dont have anyway to host them otherwise i would just post them up here.

The mods for the chart with my old t-25 set up:

Jwt 4bar, bored mafs, nismo fpr, 370cc, walbro255,apexi safc, moded t-25,bb tmic, 9.5:1 comp de,stock cams, 2.5in turbo back no cat. As you can see t-25's cant produce 15psi for very long.

Those are great numbers for a 3bar ECU program and a T25!!! Wow!

Yeah Brent, I was very surprised. The dyno operator and I were figuring 230 whp. Oh, I forgot to add that timing is 15 degrees and running UR crank and water pump pullies.
