I love Tuning! Dyno'd the Ca!

[char6310]

Hey everyone, Just got back from the dynojet...pretty pleased with the results...here is a list of my mods...ca18det, s14 t28bb turbo, 440cc injectors, s-afc, z32 mafs, apexi filter, FMIC, Uras 3" catback, 3" downpipe, Greddy type s bov (recirculated)...etc.

Anyway, on Runfile 01...that was my first run without any "real" tuning to the safc, which put down a decent 229.87 rwhp, but the a/f wasn't even on the chart...haha.

By Runfile 04...we had the a/f ratio down to a respectable 12:1 (approx) and pulled a new number of 246.65 rwhp.

Both Runfile 01 and 04 were on 15psi...and timing was at 12 degrees btdc to be safe...you will also notice that my power was still on the increase, but he only ran it to a little over 6k rpm (still had more power to gain...err, haha)

On runfile 06 we bumped it up to 17psi and put down 256.68 rwhp, not to bad. Here are some pics of the dyno and the dyno sheet...

enjoy and by the way, i am open to comments....thanks!

NICE

[ca18detizzle]

Niiice! im looking at the same setup.. pretty impressed with the safc...

[c-rad]

6k??? man, run that thing to 7500!!! Numbers look pretty good though.

[RMiller]

Great numbers. Maybe that's about what I put down.... What was timing set at for the best run? 12 btdc is pretty retarded. Why didn't you advance the timing and instead raised the boost?

I ran it at 12 btdc just to be safe... I think that if i would of ran it at 15btdc I would of gotten more horse....I will possibly change it sometime, but the car seems to like it where it is at the moment...overall, i didn't want to blow up on the dyno...haha, i used this more for tuning the safc, and less for numbers...but i feel i still got both...

[biosehnsucht]

keep in mind fixing the timing will make the tuning you did on the safc now obsolete and you'd have to do it again to be safe.

[char6310]

yea, true...good point...I will most likely leave it where it is considering she is running like a champ, and still pretty damn fast...

[c-rad]

Also to note, the torque curve is nice and flat.... Good job once again...

[float_6969]

Perfect dyno curves man. Looks just like it should. Were those the measured numbers, or the corrected numbers?

[Turbogixxer]

Rev it higher, your torque has not fallen off yet.

12bdtc my car would be slugish as hell , and run duper high EGTs hmm

[char6310]

By the way, these are measured numbers...

[sil_eightyRPS13]

hmmmmm.....numbers should be a bit higher at least 270hp range i was able to get 227 rwhp out of my silvia with a SRt25 my mods only included a GTR fmic, hks intake, 3inch exhaust with stock down pipe not cats.

looks good keep up the tuning it should get better.......
