Big16g power gains before and after FMIC

[WICKEDTEEN84]

i was just wondering what kind of gains can i expect from using a pretty decent fmic compaired to the stock side mount?

just looking for dyno charts
quarter mile times
or just explain to me how much harder the car will pull


i got all the basic mods

b16g turbo
ported exhaust manifold, turbine housing, o2 housing
2.5in turbo back with highflow cat and exhaust cut out
1g bov
and lots more
i have basicly every basic mod except fuel mods and tuning

hit me back guys cant wait to here from yall

It depends on the size of the core/piping.

With a large fmic and say 2 1/2 inch piping, depending on how you route it, will cause a little bit of lag compared to the stocker. Performance gains will be minimal at a factory boost setting, because with a b16g at factory boost...like 12lbs, your not pushing the limit of your stocker. fmic gains happen when you begin to turn up the boost, thats when they become important.

Yes you will notice a difference in top end, knock counts....ec. But the big differences will be noticed when you start running more boost. Have you ever ridden in a b16g at 18psi w/ a stocker...then the same car with a fmic?? Its a night and day difference on the butt dyno. Tuning becomes alot easier also.

You won't fully realize the potential of an intercooler until you began pushing more air, via bigger turbo or more psi, but it will make a difference.

-Hope it helps

im also pushing 15-16psi right now daily drivin and i have also never cleaned my stock intercooler so have any of you guys cleaned your intercoolers and got some decent gain.

i was just wondering all this because its starting to get gold it was about 50degreeze the other day an i have never felt my car pull so had ive always felt i lost proformance when i switched to the big 16g

i have 18g turbo, 550cc, dsmlink...but smic. Dsmlink says i have 300whp and 310tq, and im getting knock once i hit 3rd gear (int temps are high too), im running like 23-25psi. Im sure after i get my fmic ill have WELL over that. also ive never cleaned the intercooler, just sprayed it with a hose... wil i notice any diff?

Clean it. I cleaned it when I swapped to my ever so controversial, made in Taiwan, evo3 gt 16g (which is kicking arse by the way). I have no way of checking it with data to see the difference, but I know it should be better because it looked like crap before I cleaned it on the inside. I also just used rubbing alcohol. Threw half a bottle in, capped it, then swished it in there. Drained it...repeat. Airflow is affected when the walls of piping are dirty/gunky on the inside. The smoother the walls, the faster/more air can travel.

More importantly, you won't heat soak. Even at 15 lbs with moderate temperatures you'll heat soak the stock SMIC in a few pulls. Imagine trying to tune with that huh, the FMIC will help regardless by cooling the intake charge.

Well I switched from a HRC side mount to a victory performance front mount & I gain 2 lb/min in airflow (~20hp) not counting the extra cooling effect of the fmic. The car pulls alot harder. @ 18 psi before I would see some knock on long pulls. If I started in first by the time I was 3/4's of the way through third I would see knock & in forth, pulling the timing abit. With the fmic I go through 5th with zero knock, no timing pulled and was actually able to add 2 deg from 6000 rpms up. Fmic's are great

All these threads to back up what I've I said and I get no good REP???? Where is love at

 

[WICKEDTEEN84]

i bought my turbo from a guy that works at a rather large turbo making company im not gonna say any names . but i was told he ran 11's on this turbo its supposed to be a modded B16g flows more like 600cfm's.i can build about 3-5 pounds of boost at 2000rpm's but it seems like when i had the t25 on my car it had so much more power. the temprature where i live is usually arouund the 90's. the only time i felt like the turbo had some major power was when the temprature was around 50 a few days ago the car was loosing traction at 50mph's. so im hoping to get a fmic and this will solve me power hunger for a little while. it sucks the temp didnt stay low for very long.

but what do u guys think

 

[kgtalon95]

A modded b16g is probably a milled out tdo5 housing with a 20g wheel crammed in it. SBR Sells one, the bastard 20g, FP's is called something else. They are good turbo's but pretty pointless as far as efficiency goes. Yeah it would be easier to get into the 11's with one over a standard b16g, but you'll never have the power of an actual 20g. Hope you got a good deal, I think SBR's is like 800.

Going with a quality frontmount makes a difference too. When I ran the evo3 I had both the greddy and the slowboy frontmounts on my car, and I made 2- more hp with the slowboy according to dsmlink. Plus heatsoaking the slowboy is impossible, after hardruns with the greddy the coldside was warm, with the slowboy its always cool.

w/ a FMIC....you'll feel it in 3rd gear.

 

[miteclgst]

If you have ever seen a compressor efficiency chart and did the math to figure out where you lie on the chart you would understand what a FMIC will do over a stock SMIC. I have done some calculations in another thread a while back Click Here that shows what happens to turbo outlet temperature as we increase boost. This is where the beauty of the FMIC shines. A turbo will remain in an optimal efficiency range when you keep the pressure at it's most efficient level, once you move outside of it's highest efficiency range the outlet temperature begins to rise. Since Heat Transfer rate is proportional to surface area the SMIC will not have the ability to cool down the intake charge as well as a FMIC. At this point you will see detonation and thus a drop in timing and power. So while dyno numbers will be a nice way of illustrating any gains, some math and a glance at the efficiency chart will do just the same.
In conclusion if you keep your turbo within it's highest efficiency range you won't see/feel much gain when you swap to a FMIC, once you crank up the boost and move outside that range the gains will become much more noticable.

 

[v2ner]

BTW...bigger is not always better.

 

[miteclgst]

You are correct that bigger is not always better, much like any performance setup the key is not in the "size" of the parts but in how they work together. The correct combination of parts will yield the most gains in every situation.

 

[92GSXBaltimore]

my 650's should be here tomorrow, but Im still not going to be able to turn up the boost past about 16-17psi. The stock smic is just not cutting it....prob have about a quart of oil sitting in there too

 

[SlowboyCSE]

Not trying to butt in, but we have found that efficiency of the core used is KEY. You can put a huge core on, you can put a little core on… But if the core was not designed with performance in mind, you may be shooting yourself in the foot right from the get go. Here are some thermo graphic images of our 2G FMIC kit with a TDO6H 20G operating on a dyno at 26/27 psi. If your ever on a dyno or watching a friends, ask to feel the front mount from side to side or top to bottom (if it’s your side mount) to see if she is staying cool and you will instantly see what setups work and which ones do not.

Sorry that you have to click on them, i didn't want to attach them up again!
