I have a bugeye 2002 wrx with the following mods:


Engine:

VF34 Turbo
Sti pink injectors
Sti top mount
Decat up pipe
Airflow Delete pipe
Andy Forrest Ecutek remap
K&N style cone filter (not sure of make was fitted in my service and never asked lol)
Milltek 3"decat exhaust
NGK 7B plugs
Walbro 255 fuel pump
Red autobahn88 Hoses
Carbon pulley cover
Carbon slam panel cover

Im producing 340/340 but wondered if it was worth the 200-300 pound to get the fmic fitted.
What do u think. thank you

 

I think you would be better off asking Andy if he thought it would be better on that spec, You may gain a few ponies but you will also add a little lag.

 

Agree with the above, an advantage would be that you have constant cold air, so no heat soak, cars keep producing to its potential, rather than backing off when intake temps get high with a top mount.

 

ooohhh!!!! lag me no like lag lol. thanks for input mate . will await more replys as i want another rolling road map this year and if im gonna buy 1 i want to do it before i get it mapped

 

Is it the TMIC with the red STI letters on it? They are good for 400bhp anyway.

 

yes mate it is.

 

Your good for up to 400 with that then bud

I wouldn't bother with a FMIC personally, unless your gonna start changing other stuff.

 

i will eventually but if its good as is im happy for now will spend on something else :-D

 

I know 2 people that are running 427bhp and 434bhp on newage sti top mounts with no adverse affects, Your gearbox will go before the intercooler, stick with it, waste of cash if you ask me, gaz.

 

dont attack me for this, but isnt it better to have the air as cold as possible going into the engine?

yes a top mount will take 400bhp but engine is going to be running hotter so potental for possible failure is increased.

i put a fmic on my classic and gained 20.8bhp with a very basic spec and a knackered td04. the mapper was also able to have the mix on the leaner side as the air was cooler and denser with the fmic so my mpg went up aswell.

win win in my opinion.

like i said at the top dont attack me (there are some very opinionated people on here), just my two pennys worth.

 

hmm another side of the coin like it carry on peeps im enjoying your knowledge :-D

 

I had one on my STI when first mapped and it made 340 bhp. It was also stated that it allowed more ignition timing to be added for better mid-range performance... that was way back years ago. Still have the FMIC and she's now running 2 bar of boost on a much bigger turbo !

HTH

dunx

 

You are at the diviving line of where you will get a clear benefit. Your turbo is capable of 360 bhp with all supporting mods. If you plan to go further with your car then an efficient FMIC will show clear benefits.
Measuring air charge temperatures will help determine what benefits you may derrive. ACTs over 40C and there are gains to be had. By 70C you clearly need to take action, performance gains are considerable and you are probably adding safety to your engine.

 

What i was saying, just a but more technically.

 

cheers again every 1 and good explanation harvey u obviously know your stuff. i had to read it 3 times so it made sence lol im not too technical sorry i wish i was. but think i get ya.
