HyperFlow TMIC vs OEM v7 sti TMIC

[hunter951]

Hi everyone

So im curious to what people think on replacing the Stock v7 sti TMIC with a Hyper flow TMIC. Iv done some research and there are some varied opinions around, just wondering if anyone has had one before and what they thought or anything thats similar.

As far as i aware the thicker core is far more efficient than OEM and is more resistant to heat soak.... however some people think they are worse for heat soak because they stay hot...

Im also assuming i will need to retune as it will change flow rates etc and to check all the intake temps.

Any valid opinions welcome.

If you are going to that much effort, just rotate turbo and go front mount. I can't feel a difference in lag between front mount and top mount. Mind you I am a bit senile.

Dont really want to go to that trouble as of yet... i want to go T/S before rotating and flipping manifold for front mount. Can get this for 250... so just a bit of a upgrade for the next year or so.

I've had two be5 legacy's, one with a standard tmic (be5a) and my current one (be5d) with a hyperflow. The hyperflow is heaps bigger than the stock one but definitely still affected by heatsoak. I can't tell you which was worse but guesstimate them equal for headsoak.

The hyperflow can probably flow a bit more but I've never heard of flow being an issue on a standard legacy ic.

And I'm looking at fmic for my engine swap.

bigger tmic is not really achieving anything . unless your stock one is causing a pressure drop ( restriction) due to physical size .

if its bigger it can absorb more heat from the charge air but then it has stored more heat it has to dissipate.

i really doubt a v7sti cooler is physically restrictive so my answer is no

Dony bother save yourself the cost+retune and do it when you go fmic.

Anything top mount will still heat soak

The issue isn't when getting dyno tested, or run on the track, it's when it sits for five mins in traffic and takes a couple hundred metres to cool down again

Example: Motorway onramp, drag staging lanes, stop go traffic which clears and you want to fang it

Go FMIC and be done with it

Don't bother.

The stock TMIC is plenty for any power the standard turbo will make, and an aftermarket TMIC is too small for the power any upgraded turbo will make.

Speaking 100% from experience.

Ohk well I'll pas on that then. I'm not going to piss around with a fmic until I do flipped I take and twist Turbo, like stated above which is to pricey for me at the moment.
