HI peeps

Could someone help me with this little question?

What is the max power I could safely run with accompanying mods on a TMIC?

WRX STI UK MY53.

Cheers peeps in advance

Hi Ado some run 400bhp without problem,some run 450bhp without problem..
If you are planning above 450bhp go for FMIC,with good air filter(RCM Big cone)

Thanks for the reply Jura,

I guessed there would be some variation but just wanted a rough idea,

Cheers ado

im running 404bhp on tmic and standard air box

Yes this depend on more factors,but i would say should be OK,if you planning 400-450bhp...

ben what mods you running?

You can run up to 400bhp ok but you need belly pan on to make TMIC work well

Just because a certain tuner ( fully forged motor ) managed 400 bhp DOESN'T mean it's good for a std. STI motor.
IMHO as you aim beyond 350 bhp an FMIC is advisable, mine made 340 bhp but had lots of extra timing added to help it spool.

Now running >2 bar of boost it's still going strong at over 400 bhp ( 2 years since mapping )

Ask here Steve aka The Gimp which run 400 bhp on STi TMIC with MD321T and on standard UK STi...
Again you are talking about the 2 bar boost elsewhere,but not every turbo will make 2 bar,just have look at SC46/50 range,yes are billet etc.

But unless you try an FMIC on the car, how do you know how much the TMIC is restricting the power ?

I watched a 380 bhp 2.5 WRX on the dyno today and each run suffered with increasing amounts of heat soak...

Mine has done two runs and they were identical. Are you saying that mine would manage >2 bar on a TMIC without prroblems ? I don't think so.

dont put more ideas into lee's head

This don't know without the dyno,i know on TMIC you will make 400bhp,but with good FMIC is possible higher figure..

About the heat soak,yes that's true,i must admit...

I don't think you will able/manage make this figure(2.0 bar) on standard TMIC,i say before this depend on more factors like turbo etc.

420bhp on std tmic > 06 STi spec c

dunx, is heat soak only really a problem in that specific scenario though? Run after run on a dyno can't surely be a good simulation for a topmount?

dunx

iTrader: (3)

Ask Andy Forrest how big his top mount was !

LoL

dunx

P.S. Isn't a dyno run just like a launch from the lights, and the next set... and...

dunx

iTrader: (3)

They couldn't get enough fuel into it to make any more power...



dunx

But what COULD it be making with a decent FMIC ?

That's the point ?

dunx

russmod

Surely a fmic would make more power than a tmic due to the surface area lowering the charge temps more than the tmic?

Sod all wrong with a newage TMIC at 400bhp. I have no problem on a dyno or via continued power runs on the road, with any perceivable power loss. For a road car it is fine. Continued hammering on track, I agree a decent FMIC would perform better.

Personally a couple of bhp drop at this level isn't worthy of my £500+ for road use, but hey it's your money!

Andy Forrest runs a TMIC on his 470bhp Spec C with no issues and runs in the high 10's with it.
