Went to the dyno today

[NeedCAforS13]

and made 178whp/ 162ft/lb

mods are:SR t25g w/ stock dump tubeARC side mount intercoolerHKS bov2.75 inch BRM downpipe2.75 inch Blitz Realize TT-R exhaust (quiet)pulsar electric fan on Koyo radiatorstock boost (8 pounds or so because of the exhaust/downpipe)

had it done on an in-ground dynojet at a local supra shop (AutoTuner)... paid $50 for 3 pulls. Did the first one on a stock ECU, second one on a tuned ECU I got from Paul (MovingViolation) but it's basically stock with no rev limiter, speed cut, or fuel cut (made 175 on those two) and the third one I put the Horsham Developments Stage 2 chipped ECU on and made 178hp. All three runs were pretty constant at 162ft/lb torque. If you calculate a 15% drivetrain loss, power at the crank is roughly 200-205hp. Almost dead on with a stock s13 SR (see use a stock s13 SR turbo, get stock s13 SR numbers, on stock boost). I'd like to do another run in a while with higher boost once I get my skyline intercooler installed.

I am quite happy with my stock boost numbers and my a/f ratio looks nice and solid too. All in all, good numbers for 8 psi

Lookin' good Sean! That A/F ratio is sharp and ideal. Your Hp/Tq graphs are clean as well. An overall good job if I do say so myself .

nice

thanks guys the blue curves are stock ECU the green are the Horsham Developments Chipped ECU. The stock a/f is like a straight line, lol.

another thing to note, according to my tach (in the car) the operator was taking it to 7300rpm on the stock ECU and 7500rpm on the tuned one (I know, it can take more rpm, but I don't feel like risking anything since I know it won't make more power above there on a t2small). I don't know why the printout shows it stopping at 7000rpm... maybe it was because we were taking the reading from the loop on the back of the coilpack harness? I dunno...

That kind of makes me sad. I have nearly identical mods except that I have a 3" o2 housing and 3" back to a 3.75" catback. I see about 9psi. I was hoping that it made better numbers than that, but that is still strong! I need a T28 and a stand alone:(

ah sean you make me wanna get another ca... i miss mine already

[81na ZX]

That post makes me sad....

Haven't been able to pay $50 for 3 pulls anywhere around here sence the late 90s

Car's looking nice too

Congratulations Sean! I called you about earlier to see what numbers you pulled. Call me later or I will try to call you to drop off the PS hose.

[float_6969]

It looks great man. Congrats! I haven't shopped around much here, but the only Dyno I know of in Topeka Charges $60 for 2 pulls. Kinda sucks. I'm hoping to find better prices in Kansas City...

[sdtouge]

nice numbers man.

your car is really clean too;)

[WeldingHank]

i can get 1 hour of dyno time for $45 in CT.

[ca18detizzle]

nice@@!!

[NeedCAforS13]

thanks guys yeah the dyno is going to be sold here soon so they're doing discounted rates. If anyone is in central florida its $50 for 3 pulls or $75 an hour with wideband o2
