As title does any body know or even better people with sti top mounts list their power on here.

Very greatful.

Nick200

Jesus has nobody got one on here on any modded car or on an sti???

I would've like to have known a realistic figure with this i/c(real max limit)

Hi Nick,

A friend of mine has an Sti 4 and it runs at around 1.3/1.4 bar boost. I don't know what power it makes though, and how good the cooling would be at that boost level.

Would be interesting to know as I have a UK MY98 with this intercooler and will be going for more power soon.

It would be interesting if people could be bothered to answer, only take a min or two.

You're asking a very open question expecting a specific answer.

Sti4 top mount with what other mods? How much safety? For track or road use? An intercooler is only a small part of the equation.

Andrew...

is it a jap sti4 or a uk sti4? some ppls on here have got away with 350bhp with stock intercooler. you might want to speak to RICHWILD, he has a pretty powerful machine using standard internals.

cheers

Never heard of an STi4 UK ....

Rich's cars both have uprated intercoolers, an MRT TMIC and a HKS FMIC. As far as im aware he's never used and STi4 intercooler. Either way as said above the question is too open..... depends on the turbo to a great extent along with all the other bits and bobs. Personally i think that above about 325-330bhp the TMIC would struggle, even at that sort of bhp and the level of boost needed the inlet temps migh be a little too high for my liking.

Its with a vf28. On a uk my97.
I'm asking for a ballpark figure really, just want to know if I'll need a front mount?
I dont really want to spend any more on the soddin money pit.

Did someone mention me?

I think what has been said so far is pretty much right.

There are a lot of factors to consider in determining what is a SAFE power figure with a top mount, like the turbo, the fuelling (eg uprated pump) and whether you use octane booster or not.

Both myself and Trout (that I know of) have managed well into the mid 300s on uprated (MRT) top mounts, but on the OEM I'd agree with Tone that (guessing) 320-330 is pushing it a bit. That's not to say you couldn't run more (with all the necessary safeguards of course), but if you did you'd be right on the edge of things. A VF28 is a smallish turbo, so running high boost will be putting a fair old amount of heat into the inlet charge for the TMIC to handle. So, if you haven't already, and you plans are for 300+, invest in a Knocklink for sure. Are the fins of your TMIC all straight or are they a bit mashed? as that will also make a difference.

For any more power a FMIC is an expensive option, but pretty much essential really, I'd say.

Nick200

Nice answer m8.
The i/c is mint but as I am after 300+ I might think about trying to make a non subaru jobby fit.

Cheers All.
