austin42008 Posted February 8, 2011 Share Posted February 8, 2011 Looking to do a fmic with a vf48 with stage 2 mods without fuel mods how much power could I expect anyone with a similar set up also with a good tune wanna see some dyno sheets if people have them Link to comment Share on other sites More sharing options...
austin42008 Posted February 8, 2011 Author Share Posted February 8, 2011 I guess my question is how much power would I get with a vf48 and fmic with a good tune Link to comment Share on other sites More sharing options...
Spec B Posted February 8, 2011 Share Posted February 8, 2011 I have a similar setup (vf43)..depending on the dyno, you will probably get 285-290 whp - maybe 300-310whp with fuel upgrades. Here is one of my early road dyno runs...this is with DW 740 injectors and AVO Pump. After tweaking the tune, I got a little more out of it.

LosAngelesLGT Posted February 8, 2011 Share Posted February 8, 2011 OP I ran a vf39 FMIC and no fuel mods. Was good for 8.4 @ 86mph in the 8th. A little under 300whp and quite a bit over 300wtq. As you can see I've since gone on to 850cc injectors and e85 fuel but am still on my "little" turbo. How about you have an auto, it eats numbers on a dyno. Dont be concerned about numbers and unless you do an IPT valve body mod and a tranny cooler you dont want to add too much power to that tranny unless you are planning to do work to the tranny later.

austin42008 Posted February 8, 2011 Author Share Posted February 8, 2011 Swett that Those numbers are pretty much what I'm looking for around 300. What fmic are you running Link to comment Share on other sites More sharing options...
gotsugg Posted February 8, 2011 Share Posted February 8, 2011 RacerX is the best bang for the buck. See link below. BTW, you can hit those same numbers on a TMIC. What's your reason for wanting a FMIC? http://legacygt.com/forums/showthread.php/www-infamousperformace-net-grand-opening-149511.html?t=149511&highlight=racerx Link to comment Share on other sites More sharing options...

What's your reason for wanting a FMIC? Looking to do... a vf48 He is looking at FMIC because vf39/43/48 are STI fitment not LGT fitment:rolleyes:. EDIT: FWIW OP I see what you are doing here. You were checking out the STI turbos in F/S threads. Consider the following... BnR16g + TMIC (less hassle, oem fitment, more expensive) vf39/43/48 + FMIC (used turbo is cheaper but is still IHI style and will wear out, FMIC in a TMIC car requires some "living with") On stock fueling the TMIC gives similar enough results with less hassle, more oem fitment with a TMIC. The TMIC + 16g will be more expensive. Since I have moved on to bigger injectors, fp, e85 fuel, etc I am glad I went FMIC. If I stayed on oem fueling I probably would have been just as good or better off TMIC because of ease of maintenance. GL! Link to comment Share on other sites More sharing options...
austin42008 Posted February 8, 2011 Author Share Posted February 8, 2011 I plan on haveing th sti turbo sent to bnr when I get more money have It made as a hybrid 18g then I will do fueling mods just wanted to know what area of power people were hittin without the fuel mods and a good tune Link to comment Share on other sites More sharing options...
Spec B Posted February 8, 2011 Share Posted February 8, 2011 I am running the XO2 FMIC. I would go with the Racer X if I had to do it again...RacerX just fits better. But for pure bang for the buck...XO2 is still king IMO. Link to comment Share on other sites More sharing options...

Going to the STI/WRX fitment does not mean you have to go FMIC. There are other options. Granted, they don't look as cool but they work great and are very cost effective. http://legacygt.com/forums/showthread.php/tmic-under-300-105992.html?t=105992&highlight=%24300+TMIC Link to comment Share on other sites More sharing options...

Spec B Posted February 8, 2011 Share Posted February 8, 2011 +1 on performance. I have tuned my car with a Perrin TMIC before upgrading to the FMIC...same tune same weather, the FMIC made more power consistantly. Link to comment Share on other sites More sharing options...

rtbrjason Posted February 9, 2011 Share Posted February 9, 2011 +1 on performance. I have tuned my car with a Perrin TMIC before upgrading to the FMIC...same tune same weather, the FMIC made more power consistantly. How much power are you thinking with just the switch to FMIC from aftermarket TMIC and your tuning changes only? I went with the IPR for ease, "stock like fitment" and oem looks etc, though part of me still feels like I'm "doing it wrong" based on the cost of the Racerx..

Spec B Posted February 9, 2011 Share Posted February 9, 2011 I saw about 10-15 whp on airboys sheet while on the stock vf40. The airflow jumped about 15-20 g/sec. When I turned up the boost with the TMIC g/sec stayed flat, I made nothing, with the FMIC it made a little more..5 g/sec (maybe). So total, was about 20 g/sec. And I was still hitting 18psi by 3100-3200 RPM. Link to comment Share on other sites More sharing options...
LosAngelesLGT Posted February 9, 2011 Share Posted February 9, 2011 I plan on haveing th sti turbo sent to bnr when I get more money have It made as a hybrid 18g ^not a good option... So you are going to ruin a perfectly good STI turbo? You do realize that BnR rebuilds vf40 in hybrid for LGT fitment. Not vf46, not vf39, not vf43, not vf48; because the vf40 housing is great to hybridize and yeilds great results. If my vf39 gets sent to BnR it will be rebuilt as a vf39.
