I bought a new turbo setup from Driftedfc3s and I had it dynoed just a couple of days ago. T61 turbo, T4 .84 hotside running 11-12 psi boost. I have to look at my timing chart but I think I have the timing down around 24 degrees at 95-100% load from I think 5500 rpms and up. I don't know what happened to the AFR logs on the dyno, but my logs show mid 11's for AFR's. They told me it was probably there sniffer acting funny.


Rtek 2.0, Greddy 4x720's, rewired Walbro, Aeromotive FPR, Greddy FMIC, HKS log manifold, Tial 38mm wastegate with 8 psi spring, Greddy Profec B spec II.


Temps where around 60 degrees and humidity was around 50%.



Highest horsepwer recorded was 324 and highest torque was 259.

















VIDS:

 

Nice numbers!

 

clean looking car too. I'm impressed you did that kind of power with the stock AFM

 

Nice numbers!

Really nice lookin' FC!

If it's really 24-degrees of total advance, that scares me!

If you're talking about the DynoJet wide-band that you stuff in the tailpipe, it doesn't read accurate on a rotary...dunno why.

Yeah its the up the tailpipe type of sniffer.



From my reading it kinda scares me to, but I'm still learining everything at this point. I'm still learning how the Rtek adjust timing and it gets hard sometimes because it adjust with load vs rpm. Where the update should change it to psi vs rpm.


I'm really suprised myself that it made that much on the stock S4 AFM myself.

 

Some street driving videos would be super nice! How well does it get traction in 1st and 2nd?

 

I got to ride in 95nracer's FC yesterday and the little bit that I experienced was fun as hell, when it boosts you go back in the recaros quick. very nice. made me excited to be finishing mine.

 

Nice ride.... I'm looking at running about 16 lbs

 

Im interested as well... I remember when my old s4t was for the majority stock; the SAFC would peak the airflow meter at something like 75% (whatever that meant) when actuated by my hand OR under WOT. I'd say thats about 250rwhp in comparison I'd guess... At a certain point the flapper is completely open and no longer metering aditional airflow.

 

now thats what im talking about! cant wait for my car to be worthy enough to post on here! great numbers man

 

woah, omg i love your car, that is a really nice, clean car you have

 

you need to figure out your what timing you're running. post it up here. Ted is right. 24* is pretty agressive for 12psi. most people start at about 20* at 10psi and go down about one degree per psi. so at 12psi you need to be at about 18*.

can you adjust the timing split on the rtek ecu? you should be running about 18* advance and 10* split. your afr's look good, but you're flirting with a broken apex tip running 6* too much timing

edit: nice car BTW, makes me miss my last TII!

 

Sweet! I just today traded my daughter for the exact same body style car, except it is hot pink. Doesn't do too much for my macho man image, so the color will be modified for sure. I'll post pics later, too may honey do's happening today.

I'll be going thru the drivertrain from top to bottom soon, and if I decide to keep it, I'll want to build it similar to yours. So please keep us up to date on how it performs.

I live in Delaware, and they are pretty sticky on emissions and car mods. How is your part of NJ for inspections?

 

I'm stationed up here, but I have New Mexico tags. NM tags = No emissions


Good luck with the project.


Yeah I looked at the logs and timing is 23.5 advanced and split I haven't touched so its at stock levels. I'm going to make some changes and see how it runs. I should be heading out to Atco Raceway Tuesday to tests things out.

 

make sure you check your split table on the rtek, cause i believe when you change the leading, the trailing stays the same, it does not automatically keep the stock split. but i suppose you probably already figured that out

I remember i had to totally redo the timing tables, pita.. the stock timing table was like 35 deg advanced at 100% load! i had to change both the leading table and the spit table to get it all right, took forever on the pda lol. Im currently running 15 deg split, 20 deg leading adv at 100% load (~7-8psi), blended with the stock map down to 45% load
