whats the furthest you can go with a TMIC?

and is there any better for a classic than a STi-8?

if your looking for arounf 420-450bhp

would any TMIC cut it?

dont really want to go front mount but want to break the 400 bhp mark..

is liquid C02 onto the intercooler the only option if you want to stay stealthy?

cheers

 

Andy F has run 470bhp and over 500lb/ft of torque on a newage sti tmic

A black painted FMIC with a N/A impreza hood. That's stealthy!

 

you can run 800bhp on a top mount if you want, you'll be loosing hundreds of bhp due to heat though.

realisticly you'll start to loose power after about 300bhp

 

"The effectiveness of the OE intercoolers varies throughout the years. The early 93-96 slanty type will limit power to around 310 bhp whilst the 99-00 can run to around 330 bhp. The STI MY01 onwards is capable of over 450bhp with an appropriately sized turbo."

is that on a everyday car ?

heat will be too much .. suppose it'll have to be front mount route to save intake temperatures at that power.

 

also makes no mention of needing to change the internals of a uk classic to run a safe 450bhp. i wouldn't go along with all that is said on that site.

jap performance mag did a test a while back and made a difference of 307bhp on a top mount (wrx one), 313bhp on a hyperflow top mount, 322bhp on a front mount. test was done back to back, same car, same mapper, same day.

also i believe harvey did some tests and found it made a big difference to inlet temps

 

hi mate gd point.

the car im talking about is a forged classic, so internals will be fine

i want him to be daring and try 450bhp with STI-8 TMIC and some liquid C02 for Cooling. and see how it is for everyday use .. at that power i doubt itll be any good, will run too hot.

maybe for a car around 380bhp with early spool itll be perfect, just for those hot days.

if you run off this thread i made a while ago

https://www.scoobynet.com/general-te...t-benefit.html

thing is , its just easier and probably more cost effective to go front mount . think ill just have to wait and do this lil test myself

 

You would be better off looking at water/methanol injection to cool the charge.

spool doesn't mater, lag from a front mount is a myth as well

only situation where i know front mount induces lag is when your running a small small turbo like a td04, and even then its not always the case.

 

both mean carrying a tank and the liquid around with you, plus it runs out, front mount doesn't. although i bet the metal front mount set up weights 5-10kg more than a standard setup

 

chargecooler setup with tmic?

 

gt_ maxer can you exapand on what u mean? im new to this stuff.

and i think for daily use tidgy is right, front mount seems the best and most reliable.

banny: what sort of effects would water/meth have?

 

i know for my track subaru, if i can make enough space in my engine bay i will go for a pwr chargecooler or both chargecooler/tmic setup, less pipe run etc.

 

You could get those variances using the same car with no changes (same day, same rollers).

If a front mount offers more bhp without any downsides, then why do the TMIC cars seem to outperform FMIC cars from standing start acceleration (ie. 1/4mile - bhp for bhp)?

Maybe they are benefiting from all the hot air due to the TMIC inefficiency

I'm not saying FMIC don't have their place, but lets not be blinkered as to the the pros and cons of both.

I would happily run 450bhp on a STi8 TMIC.

 

Some good common sense there I'm running 415bhp on a Hyperflow top mount in my everyday road car and it performs just fine with a lovely throttle response that was missing when I had a FMIC fitted to the same car. If I was using it a trackday weapon, then maybe I'd consider a FMIC; however, for road use a TMIC is fine. I'm having a built engine later this year and even with 450/450, I'll be sticking with my TMIC

 

bob i take it you'd have a charge temp guage just to monitor it?

as even tho this car will be used everyday, the person also does 1 or 2 trackdays a year or drags etc.

so will need to keep ontop of this.. if you say ud happily run 450 on it, i suppose the liquid C02 can be there as a back up for track?

also on this question, anyone know the best place to but these kits with the cryogen loop?

 

You would end up with more pipe run using the pwr charge cooler and a top mount than you would with the pwr + front mount.

Dont forget the pwr runs inline which would be a right pain in the **** fitting with the tmic.

 

biggs not pwr with fmic i said pwr with tmic..something tells me you had a 5gtt at a stage? there is less pipe run with a pwr chargecooler and tmic than with just a fmic, going by the route ive worked out.

 

Yes that's me Gareth... I know you was talking about a tmic with the pwr, but what I was saying is it would be near impossible to run them both due to the design of the tmic y pipe

 

All I can see in that Jap perf mag article is a poor cooling fan for TMICs being used at scoobyclinic

Temperatures on the road for pre and post IC types would be more revealing, but I would be tempted at that HP to use an FMIC if there was a loot more track and esp. drag runs due to heat soak when stationary.
The heat is lost very quickly, but that may not be quick enough at the flag or lights.

how do biggs mate! ill have a wee look again 2nite but i thought there was room.

 

I'm running 402.5 (had to add the .5)bhp on a STI7 TMIC and thats a everyday car.

Steve

 

The use is progressive, ie only uses it on boost, so with my kinda driving its running about 10% of fuel, 12litres water/meth to 120litres fuel.It would use a lot more at the track! The system has a safety element in that it wont allow boost if something is wrong, like if it isn't switched on or isn't getting liquid for some reason. I sourced a spec C boot water tank.
It's more expensive than a FMIC but I would have thought it more of a constant in cooling the charge.

 

the topic on here and andys site isnt in relation to internals whether it be classic or newage

are you saying Andy is talking sh1te then?

 

Yes thats his everyday car - i think there is an article in jap performance on it ?

 

Hyperflow TMIC's work very well - good for at least 450hp

Scoobyclinc ran the above on a 22b with a 2.5L + MD321T.

451hp / 484 lb

 

Its all about the amount of boost your running and on what turbo. charge temps @ 20psi on my standard turbo is gonna be alot warmer than on a larger turbo.

 

That has a lot to do with the amount/requirements of an intercooler. A turbo charger that has had the boost increased past a given point will give a higher amount of boost but also create an increased amount of heat.
So simplistically fitting a more efficient turbo charger will produce the correct amount of boost but with less heat, however this may mean a turbo that has a lot more lag as it is not working flat out.

 

just a quick question.what version are you trying to fit a v8 stitmic? after weeks of homework/reading etc. decided to fit one on my v1 sti wagon,couldn't get an sti one cheap enough so got a new age wrx one(almost equvalent to a v6/7 i think but still smaller than an 8).3 weeks later still working on it and i've got a mate thats an ali welder(aerospace).had to hack 20mm out of the plenum,blank the bov off,move the 2 lower pipe forward 15 mm and the nearer it get's to fitting the more bit's catch the structure.wish i'd gone the tried and tested front mount route but i'll not be beaten by a lump of metal.turn's out the later manifold had a big re-design my subaru man told me inbetween chuckles.
