Dyno'd stock S13 SR20DET - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Nostradamus · 04-18-2005, 04:41 PM

Intake, full exhaust, and SAFCII. Scans could be a little better.

I added more fuel in the low range to bring the AFR down and fix that torque but since there was no fans and practically no rest between runs the IC got heat soaked. Even though the AFR looked better in the last 2 runs it didn't gain any HP or TQ due to the heat.

Was really trying to break 200whp.

Any comments or suggestions?

i pulled similar numbers on a mustang dyno(189 whp/176tq)....but that should be about right....mustang dyno's are a little lower than dynojet....i have t28(stock boost),full exhaust, fmic, walbro 255lph...now just up the boost a bit then you will hit numbers you are looking for.

Try FMIC, full exhaust, and ~14psi...that may get you to ~240rwhp.

But with stock boost (~7psi)...close to 200rwhp is good.

8psi fmic on a KA gets you 235whp

To the best of my knowlege a stock SR (S13) with the stock exhaust, intake, IC, boost usually puts down about 165-175 whp.

moreno · 04-19-2005, 08:15 AM

not bad, maybe if they had a fan in front of the car you might of gotten better numbers

ok.... well maybe i mis-understood what the guy told me. he probably meant that i was running close to 240rwhp cause i got apex'i n1 cat back with custom 3 inch downpipe and no cat and 13 psi with 255 fuel pump.

Yes 13psi should be close to 240whp like orion said, which is 6 more psi than I'm running so we're all consistent.

and that 240ishhp is on stock t25?

I assume that's what he's running.

Rusker · 04-19-2005, 01:50 PM

Andrew Bohan · 04-19-2005, 02:11 PM

If that question is for me then yes I am running stock boost stock everything except intake, full exhaust, and SAFCII. Boost sometimes hits 8psi.

mr_240sx · 04-19-2005, 03:14 PM

im also running t25 making an estimated 240ish rwhp.

In your sig it says that you have a KA-T, if so then my settings are irrelevant to your setup. What I did was added about 10% more fuel at like 2000RPM and then taper it off to 0% at about 5000RPM. After 5000RPM I subtracted like 3% across the board. Those settings are for HI-THROTTLE only; I didn’t touch LO-THROTTLE.

As for DEC-AIR just read the instructions it’s pretty straight forward. DEC-AIR only seems to work when the car is warmed up and when you try to start it in the morning it’ll stall out so I keep it off and recirculate my BOV.

With a couple more runs I could have tuned the AFR’s pretty good but I didn’t want to beat on my car too much for minimal gains. When I build the motor then I'll properly tune it with a standalone.

khoadogg · 04-22-2005, 03:19 PM

damn what if you run w/ a 'race-only' pipe instead of the cat and the jDm yO ground wires

mr_240sx · 04-23-2005, 12:07 AM

how much more hp would you get if you didnt run with a cat?

Must reinforce the fact that he was dyno tuned. don't expect numbers out the box like his nor using his s-afc settings either.
