fmic to tmic?
would i lose or gain anything by taking my fmic off and putting a decent tmic on car?
car is running at 420bhp i was lead to believe that over 400bhp you need a fmic?? cheers:thumb: |
Think the flow limits from a TMIC are around 400 bhp. Look for posts about going from TMIC to FMIC.
|
It would be a backward step as far as future modding is concerned. Also, the FMIC is safer for the motor - ACTs are way down, compared to a TMIC.
Don't swap it (seeing as it's already in place). |
As a very well known engine builder told me when asking 'what change the interwarmer,i should think so' lol
Stick with the fmic mate:thumb: |
cheers
|
Hey, PDR, got the Z32 back - cheers. :thumb:
BTW, my car's now at API having those mods done... inc. a FMIC (just to keep my comment on topic! ;) lol) |
youl see your spool go though the roof, andy forrest uses a deep core on hes track car pushing 420 bhp

I know of a couple of cars that are running 420-430bhp on the standard sti top mount, v7 jdm sti & 07 spec c, but why change as there isn`t any really massive gain to be had by swapping apart from spooling up a little bit quicker if your lucky depending on your set up, Personally i`d leave it as it is if it were mine.

shorter pipes,smaller intercooler less time to fill with air, just mine feels alittle laggy on the vf35 with a fmic if some one got a printout (vf35&top mount) il postmine and can take alook :Suspiciou, what your experience harvey?
lag is so little comparing a front/top mount you'll never feel any difference at all. Feelable lag issues are setup issue, not front mount issues. |
My experience and that of many others is that on an efficient FMIC such as Hybrid and proper mapping there is no appreciable increase in lag and the power increase, just from a TMIC to FMIC swap and mapping is very noticable on the ar5e dyno and supported by back to back testing.
This lag on a front mount is very much overdone. Sometimes it is people without direct back to back experience regurgitating the opinion of others. The cause of poor response, if it exists, usually lies elsewhere starting with a crap kit, some other change including DV and tubular headers or lack of mapping. Pooeater. Are you suffering lag since changing to an FMIC? What else was changed at the same time? |

fmic on the car wen i got her, car was on the dyno sunday showing full boost around 4500rpm alittle late for a vf35 i thought, suspecting the fmic and to be the cause of this
|
Yikes - that's 27 psi on a poor little Vf35 :eek:
I see from elsewhere that you quoted: vf35/1.8bar gems ecu fmic inducion k&n full H&S exhaust gt spec headers/uppipe 740cc inj forge actuator forged 2.0l built by ZEN mapped at the racing line made 350bhp/390lbft Its not producing that anymore so something has changed? Just what is going on with that run 2 boost curve? Time to point the finger away from the FMIC causing your woes. |
nothing changed just diff dynos, now its 369/341? run 2 is abit funny with the boost dv i think, be interesting to put a tmic on and see what happens

If you want to come to Darlington by appointment we can probably identify the issues and to do that would cost nothing. Fixing the issues will cost something but without knowing what the issues are I cannot tell you more. |
PS: Full boost on a VF35 at 4500 rpm is 700-1000 rpm more than it should be.
There is clearly something wrong and you need someone you can trust to get to the bottom of this in case it causes permanent damage. |

After looking at your dyno sheets I'd be getting it checked ASAP. Throw up the AFR from the run, its on the same page as the boost plot.

the reason i asked is due to lag im getting, but reading what harvey has put i think i need to step back and think more logical ???

just to compare, mine on a vf34, compare the fueling between mine and yours http://i14.photobucket.com/albums/a3...ods/wheels.jpg and power graph, http://i14.photobucket.com/albums/a3...20mods/fly.jpg |
Nice graph there tidgy mate from vf 34,is that classic or newage?
|
cheers, its a classic uk turbo with some other tweeks as well lol
