so it's been almost a year since i first dyno'd my car with the S/C. i made 170whp and 155ft-lb which was much lower then i expected. when i got this dyno, i had the stock s/c setup, AW header, draxas s-pipe, and SP2 axle back.

Now, in addition to my previous mods, i have since added the NST 9.5lb pulley, custom 2.5" midpipe, modified Injen CAI, and tuned with Greddy Emanage Ultimate by one of the best tuners, st00pidfast. and i am very pleased with the results



212whp 179ft-lbs @8.4 psi!

and if you notice, that is at 8.4 psi! so i'm missing out an 1.1 psi. gotta tighten that belt down some

Well, at first, running on TRD reflash w/ 9.5psi, a/f @ WOT was 13.8-13.9, which is VERY lean. The reflash is also very conservative on the ignition. Added some fuel and ignition and baam, the power band beefened up immensely. Kept increasing ignition by 1 increments until power stopped climbing. Then decreased it back to keep a safe margin.

 

hey can you post the numbers...i cant see the graph since they put web blockers up here at work.
thanks!!

 

there ya go!

 

very nice. congrats.

 

So you're pleased with the numbers, but how do you feel about it's performance? Are you now 'done', or planning more power mods?

 

yah i'm prewtty much done for now. i'm very satisfied. the tuning alone made a HUGE difference. Made everything smoother and it PULLED! Took 1 hour to tune.

 

very good.....took you too long.

 

damn congrats man, thats really good all you need now is a better bypass valve to pick up that lost 1.1 psi and you will probably be stting right at 220, also looks like you were still pulling at 6300. Good job, keep up the good work.

 

oops, forgot to mention i already have the forge 007 bpv with the red spring in there right now. the lost boost is probably due to belt slippage or belt not tight enough.

 

be careful with that tune. 13.8-13.9

 

it was running 13.8-13.9 before the tune (TRD reflash). after the tuning, it runs 12.5 or lower at WOT

 

Good Job RS1.

 

You gonna make me wanna keep my s/c,,,,how much you think you gained from the tune only?

 

s00pidfast does have quite a reputation in Houston as one of the best tuners. Glad to see those numbers, now just imagine what you'd be running with the extra 1.1psi and a manual transmission. Very nice tune..

 

st00pid fast tuned me originally

 

Congrats man, nice numbers. Take that thing to the track and see what it does. Should be really consistant with that auto.

 

thanks for the comments! i was gonna go to the track yesterday with some other ppl in town but it was raining . we're gonna go next friday along with a bunch of other people that are getting tuned today so it should be even more fun

 

Wow 13.8 at wot I'm taking it easy on mine till I get my wideband, do you know what you where cruising at a/f? I had talked to garage about a cai on his s/c and he said he was at 12 wot ? is the tuned diffrent for autos

 

yeah that a/f ratio was from the TRD reflash when using BOTH 9.5lb pulley and CAI so the a/f might be safer when using one or the other, but in my case a/f wasn't too safe. i figured it wouldnt be which is why i installed the CAI the night before going to tune in the morning (i never got on it on the way over there either). as for cruising a/f it should be 14.7 since it is closed loop.

 

i thought stock s/c dyno was at 190-195 whp?
