Comments:

Upgrading from stage 2 required more holistic approach. I wanted to stay away from FMIC for many reasons and my goal was to have similar or better than stock spool for my daily driver.

Having said this my stock STI TMIC stll became a bottleneck after correcting things with the air inflow. By this i mean that with Dom 2.5 you would find stock inlet and intake to be restrictive. Also I could have improved airflow further and squeeze anoth 15hp or so by removing TGVs. Most critically with this setup I am pushing so much hot air that to keep detonation away and eliminate knock I had to consider either 1) better than stock Intercooler or 2) Chemical intercooling (i.e Meth injection). I went 100% Meth route initialy

Here is the graph from old ICS Performance Tune:



Update as of 11-23-09: Installed EFI Logics EJ shortblock with forged pistons, APS DR525 FMIC, FP HTA Green (56lbs wheel) turbo, Cosworth Intake Manifold, AP Fuel rails and Regulator, Grimmspeed Up-pipe and Phenolic spacers. Retuned for 75/25 % Meth/Water ratio.

I have specificaly asked Tuner (Chris from EFI FTW) to dial power back (like10%) from peak levels to leave some margin of reliability for this Daily Driver

New Mustang Dyno Graph as of 11-23-09:

get an account with www.photobucket.com it is easy to upload pics or scans and then just copy the IMG code and paste it and it will show up on the screen.

nice #'s BTW, if you decide to get a bigger TMIC get the Spearco/ESX. It is PHENOMINAL!!!!

I am contemplating APS TMIC, but there is no immediate need per se with Meth running....I will wait for my stock TMIC to crack up first

My real next upgrade is clutchmasters stage 4 clutch

Thanks

nice numbers but that is scary as hell with that much boost.. where is your peak torque at? also is this with stock headers and up pipe?

stock uppie indeed

Al from dynoflash did the tune and i was reassured that 26psi is not that scary with 100% meth injection.

I am using HFS-1 and failsafe is very reliable, limiting boost to 15psi with no Meth running...

The car drives like stock in terms of reliability....

that is yet to be determined. when pushing 400 whp or near it people tend to throttle the car more. it is only a matter of time at those power levels when a piston or ringland goes bye bye. go 75,000 miles plus and then you can talk about reliability.

As for Spearco vs APS... there really is no comparison. Spearco wins on Flow, fin design, Psi Drop and overall build quality. I spent $960 with tax on my APS TMIC with the Cast ducting. You can find Spearco units for the same price. I originally had the Spearco, but the 07 has some stupid part that makes it so the Spearco doesn't fit. Spearco FTW. There are guys on here (4ST-AIR, Suparoo, etc...) that are running the Spearco with GT3076R and 35R's. They are making every bit as much power as the FMIC and spooling faster.

I understand your concerns with a front mount.

Your mod list certainly suggests the need for a larger IC, be it FMIC or TMIC.

You really won't lose too much of the spool on a 2.5L with a FMIC/dom setup.

A good tuner is going to manipulate your AVCS timing to make up for the split second of "delay" you are so worried about.

Installing an FMIC is kind of a b*tch, but it's not that hard, overall.

You can squeeze a Spearco in your car if you really want to stay TMIC.

If you decide to go FMIC, I'd stick to APS, for certain.

how about you get some headers and up-pipe and open up flow to get more power throughout the power band and reduce boost to make the same, if not tons more power.

I'm just a concerned enthusiasts. you wont have to worry about detonation because of meth but all that pressure on a stock build is scary bro.

I agree that reliability is a long-term oriented concept....Meantime, is the concern about raw HP numbers or boost pressure per se?

Different Dynos do pan differnt pictures so I am sure my dynojet 378WHP digits would be lower...say on a Mustang Dyno.

In terms of boost pressure of 26psi....it gets there only on WOT or near it. Sadly...being a "mature" driver ...who is aware of his slipping stock clucth I do not go near WOT in 5th and 6th gear on Meth. Anyway I drive most of the time with AM HFS-1 disabled and push only ~15 psi.

I am thinking of 26psi avaialble to me as a safety net in rare cases of a quick speed fix.

However I do fully realize that lower PSIs ultimetly will contribute to engine longevity...

My main concerns with FMICs are cosmetical and insurance driven. I really want to keep my car looking stock. I also do not want to cut out anything stock form the bumpwer supports...etc. Meantime I am battling heatsock quite well with Meth, heatshiled, ceramic coatings..etc.

I only wanted to go APS TMIC route coz I have other APS products installed and they all perform very very well.

This being said I have also realized by now that Spearco TMIC would be an equal or better product to invest into down the road...

I know that OEM STI uppie is catless ...but the inside of the factory uppipe is corrugated...So in your mind an aftermarket uppipe is still a good modification that will yield sizable improvement on my particular setup?

Is GT Spec Gen II 02-07 WRX & STi Header & Uppipe combo a good product to get? How much improvement I will find with unequal length headers ( i do like to keep signiture boxer sound)?

Thanks

26psi with meth is not that bad. VIREurorally runs 26lbs with meth in the 485 tq range and has been doing it for a whil enow with no issues at all. Nice numbers!

Thanks for the links..very informative indeed.

to me ....2.5 has a slightly better spool than 3.0, better matched the rest of supporting mods that I had already invested into (like 740 CC injectors) and overal seemed to be a better fit for a daily driver...I also like tons of torgue early on as I seldom take it above 5000 rpm on a street. In other words i definetly wanted better than stock top end, but lower end and midrange took precedence in my decision....

Didn't you say you are a mature driver and don't do WOT in 6th or are you saying the clutch is slipping with the HFS off in 6th???

When you disable the HFS you have to switch maps as well so its not as easy as hitting a button and your ready. Correct me if I am wrong.

Nice power out of a 2.5" but 26psi on the OEM TMIC is pure insanity. That things made to flow like ~440CFM it was made to flow just a little more than the stock turbo.

Still would like to see the Dyno sheet. I'm willing to bet that the WTQ falls as fast as it was made and drops anywhere from 150-175WTQ by rev limit.

Still very nice power Al's a machine when it comes to tuning.

i can not really speak for any other headers, i have Automaster Equal Length headers. MY power band has shifted to the right a lot. It pulls smooth all the way to redline for a stock turbo. Pretty good price but you WILL LOSE the boxer rumble. on AMR's dyno, I made 275WHP, 320Ftlbs at 17Psi on Sunoco 91 octane. that was with just a downpipe and their headers.

Thanks for compliments

I am a mature driver indeed who does not hit WOT in 6th because:

1) There r no public roads in Tri-state conductive to such kind of driving
2) I personaly dont feel the need to push the car so hard on a regular basis
3) Stock clutch is slipping at WOT in 6th after 5-10 mins of hard running in 4th / 5th.
