EWG is also just eliminating a bottleneck in the system. I know you ported your Green out, but an EWG skips it altogether. It does not get better than that.

All that said, you're still on thin ice with those rods and the above parts or deeper tuning will more than likely spell the end.

To make sure I'm heard in full. Also, since Crystel hits 27# at 4400 with a HTA86 and a FMIC, take some notes from him.

Yeah a fmic doesn't add that much lag like people claim. I have 27psi on my dom 3 at 3950. Granted its no ht86 but still that's damn good for 55lbs/min

I lowered the timing at peak torque like Crystal suggested for safety of the stock 09 STi rods and increased the timing by one degree at redline. 12* at peak torque and 22.5* at redline 7500.



I lost some mid range but It gained about 10whp from 6000rpm to redline. The TMIC is getting head socked as you can see... second pull . I am still running fairly rich 10.9-11.3 AFR from 4000rpm to redline.

So, what should I do next? This is a 68lb/min turbo it should be capable of making quite a lot more power. What should give me the biggest gains?

juan, my first and most important recommendation is you need to pick up a fmic...even a cheap one would be better than your tmic. i mean, my ssac fmic held up and performed just fine, and it was only $300.

second thing is your afr. i would recommend playing with leaning it out and see if you pick up any power. i made the most power on my setup by leaning it out to about 12.2. unfortunately, i am not really comfortable running that lean daily...so on my daily map i made the best power around 11.7.

third thing is timing. obviously, your peak tq is lower for a reason, but you still have some power on the table up top for sure. you should try adding a few degrees more up top and see if you pick anything up. obviously, if power doesn't come up, then put it back, but I bet you pick up power pretty well with some extra timing.

obviously, there are always better parts or things that are still on the "to-do" list on projects like these, but i just listed the things that would be cheap and easy ways to pick up power and improve things from where you are at right now.

Just curious, does this thing even get run on pump gas? I'm strongly considering an FP black and was wondering what kind of numbers your set up would yield on 91 or 93...

Nice thread so far though, good reading and lots of graphs

Probably leaving 40-70whp being absent from e85 to 91oct, little less with 93-94.

i dunno...it would depend on your location and specific setup...i picked up 125whp switching to E85 vs. 93oct with my FP Red setup, but that is mostly because of my high compression that i run forces me to be pretty conservative with boost and timing on regular pump gas.


...most NORMAL setups will have a difference right in the range that catface said...probably 50-75whp...

I need to get some e85. I'll be damn near 500 at that point. E85 is like magic. Lol

Yeah, E85 is awesome.



I am finally going to install my sponsored fiveO 2200cc injectors . Thanks again to Ron at Phatbotti and FiveO. These are going to help a lot so I can push my setup a little more.

I am still looking for a FMIC

The turbo xs one is cheap and does the job. Those Injectors will be the icing on the cake. I can't wait to see them installed and ur new dyno

^ i agree. the turboxs fmic does a great job at a nice price. i ran the ssac knock off version of it on my budget build bugeye.

I know I'm late chiming in, but my fmic added almost no lag to my setup. It certainly wasn't noticeable on the street and the dyno was extremely close to my tmic, maybe 200rpm off. The big kicker was how the boost came on. With the tmic it was a very steady build up, with the fmic it was nothing nothing full boost. So, lag was almost non existent, transition response was noticeable. I'm sure with a good fmic you will pick up some serious gains though, particularly with that turbo. I'd expect a good 40-50whp, but that's pure guestimation.

Yeah but the piping will not work with my APS 70mm CAI

The only piping that will works is the APS or Perrin

From my research the 4" ETS FMIC has thier own core, the garrett core that Buschur and others uses is the garrett 3.8" core. One thing that I found interesting is that the APS/ Treadstone core is 4.5" deep . I don't know how efficient is the core vs the garrett or who makes their core.

If I gain 10-20whp with the same settings (timing, boost, afrs) I would be super happy. I would not mind 200rpm if I gain power. As of right now if I decided to keep my APS CAI, that some how is not maxout .... I have to get the APS DR 725, The APS piping with the treadstone core or the perrin FMIC. I like the APS, treadstone the best but I heard that the core alone weights 30lbs.

Yeah, I was guessing that with tuning adjustments. I'm sure you could run more timing with a fmic. Probably quite a bit more if you want.

I loved my APS 525, great stuff if you can find them anyway.

Oh yeah i just noticed you have the aps 70mm. I had the same and after buying the the turbo xs fmic and realising it didnt fit i just ditched it and went speed density. No more worries about maxing out the maf.

are you sure your intake isnt maxed out? what are your MAFv?

my dom4xtr was pegging at 5 volts at 20psi spring pressure by ~5000rpm.

pretty much the only way you're not maxed out is if you have a massive post maf pre turbo leak.....so you're sucking air not being measured by the maf.

I don't think so... it hits around 4.6-4.4V and it peggs at 400grams. If I were maxed out It would go lean, correct? My AFRs are on target. Since I am fixing that transmission leak that I told you, I had to pull my turbo so we will see if anything changes.

I have to get a Kstech intake or something. Maybe I can go to speed density if Ron desires. Do you gained anything by going to speed density? what do I need to go to speed density? I don't feel like searching haha

4.6 MAFv is way too low for what your power is saying. Your green was at 4.6 volts at 20.5 psi at redline.....so this black better be higher than that at 26psi.

I guess or something is going on. I was fine with the green also.

if i had to guess, i'd say the turbo inlet is falling off the turbo. thats the most common place to leak between teh MAF and turbo.

and looking at the afr plot in post 28, something is definately up with the fueling.

I should be able to have my car up and running in two days. I am going to make sure that the turbo inlet is secured.
