Largest BHP on TMIC?
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

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."

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

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

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?

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.

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

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.
#19
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.

It's more expensive than a FMIC but I would have thought it more of a constant in cooling the charge.

are you saying Andy is talking sh1te then?
#29
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.
