max power on sti top mont?/tuning advice
 

Hi all,

I have a blob eye sti wide track ,

looking at fitting these parts (list below), should this set up make 450 bhp on my car?
and have i missed anything ,

also the only thing I can think will hold it back is TMIC , but i want to keep the car looking standard . so want to keep the sti top mount , is around 450bhp still acheviable on the sti top mount?








md321t turbo
gt spec headers and special up pipe
800cc injectors
3" exhaust/decathrc fuel pump
mac 3 port boost solenoin
simtek ecu

400 is max on top mount

Its not, just advisable to go down the FMIC route.....There is a guy on here(cant remember his name) was running 450+ on a top mount.

yeah, andy forrest ;)

so the standard sti top mount will be ok then?
( I know it would benfit with a FMIC , but just want to keep the car looking standard ish)

I have a charge temp gauge , so can keep a eye on things

thanks for reply's

My Hawk is running 406/406 on a TMIC, But I have got a Perrin FMIC to fit, so I can get the best out of the SC46!

Thats him Steve.. :thumb:

Mine ran just over 420 on a the STi TMIC. V similiar spec to your planning. 321T Perrin Headers 800cc Sard Injectors Harvey up pipe Aeromotive FPR 3" H&S Decat exhaust etc etc

BigBez (Tim) is running nigh on 500bhp on a top mount.

i managed 393 with my standard tmic and a lm450 and other bits and bobs.

we couldnt crack the 400 barrier....

what was it like on the 321t , is it laggy on the 2.0l ??

thanks

Not at all mate. Harvey up pipe really helps, as does the mapping. Mine made 1 Bar @ 3100Rpm from what I remember

I recently posted a thread on a similar vein. https://www.scoobynet.com/general-te...able-tmic.html

Still haven't decided what to do as like you, I'd prefer to keep a top mount, although prepared to go to something like the Hyperflow TMIC.

My car ran 425bhp or 415bhp ( can't remember) on pretty much the same spec you listed.

I then went for it on fmic as the MD321T deserved better.

What's the car used for bud?

Meth would have to be used to get 440+ on a TMIC, either in the fuel or water/ meth injection.
Certainly know of 443hp, Blobeye STI, Hyperflow top mount, SC46, Syvecs, 20% meth in fuel.

cars used for fast/road and the odd track day (not seriouse track use, and would keep a eye on charge temps)

I will FMIC it if i have , but want to avoid it if possible

cheers

Would like to know what mods were done to the scoop undertray/splitter to feed the larger IC with air across it's full area.

standard scoop and undertray.
