Dyno'd the s13 today

[usdm_180sx]

Props to JER! I did 195.7whp at ~4800rpm and 250ft/lbs at 4200 on the Dyno Dynamics dynamometer. This dyno records more accurate numbers than a dynojet. Dynojet numbers are 16% higher on average.

Here are the mods:SR20DE-T 180sx Blacktop Greddy turbo elbowBlitz Stainless downpipe Blitz LM FMIC HKS S13 SR20DET SSQV BOV Hot Pipe Kit HKS T25 turbo wastegate actuator (NOT tuned, running on stock injectors and ECU)Unknown Brand Test Pipe Tomei Fuel Pump Z32 Fuel Filter

Here are the graphs:

Check out the a/f ratio. At that rate I'll be richer than Bill Gates!

Man i wanna see how it will run with better Injectors

[ca18det_boy]

schnazzy

[duffman1278]

Hmm, its almost like my setup, good numbers s

[Hijacker]

How much boost?

[DrifterProdigy85]

Very nice. Id get that AFR straightened out. My guess is its the Tomei Fuel Pump and Stock FPR.

[usdm_180sx]

How much boost?

My bad. 11lbs

[boardoxmage]

195 rwhp at 11lbs?

I would think you would be making more power. I guess it depends on the dyno...

DynoDynamics reads lower numbers. Dynojet would read around 225whp

Yes that would be my guess too.

[Hijacker]

I'm hesitant to jump at the FPR being the culprit. Get a pressure gauge and check your line pressure first. Also, make sure your O2 sensor and coolant temp sensor are in good order.

You guys don't get it. The car has STOCK INJECTORS, STOCK ECU, IS UNTUNED AND BOOST IS UPPED TO 11PSI. OF COURSE THE A/F WILL BE OFF.

When i first dynod my redtop SR i had also dynoed my car on a DynoDynamics and ran the exact same setup you have on your SR, but i had the boost set for 10 lbs and it peaked to 12lbs on my hks actuater. Well after 3 pulls i put 202.2HP to the wheels at 5800rpm and 190Ftlbs of torque at 5300rpm.

and yes if you run a stock motor with stock ecu and injecteres with the boost higher than stock setting the AFR is going to be off.

A Dyno Dynamics Dynamometer is one of the lowest reading dynos out their, IIRC it is the lowest reading dyno out their.

Hey usdm_180sx did you have a standalone when you dynoed your SR because your graph looks real rough

[drftsx]

how are you able to run a z32 maf without having a afc??

[usdm_180sx]

how are you able to run a z32 maf without having a afc??

Simple. I have a stock MAFS

What who said anything about useing a Z32 maf with the setup.

[homeslicej2]

It's gonna flow more air than the stock turbo so I'd keep the boost really low 5-7 psi

[wzntha]

[redtop91]

Depends on the turbo. If you have the stock turbo your mechanic is.... confused to put it lightly. Nice #'s Norm.

[idahotuner]

i am hopen for numbers twice that. but great job. oh and it is Z32 fuel filter no MAF lol

[homeslicej2]

^^ LOL

[idahotuner]

a confused engine, so it doesnt know if it is straight or bi or gay right?
