R34 Smic Heatsoak, Is It An Issue?

[Rekin]

To R34 GTT owners;

How well does the R34 GTT smic handle on 200kw atw tunes?

Any problems with heatsoak on track days and/or long periods of spirited driving?

I currently have a r34 gtt smic on my stock r32 with plans of 200kw~ and was wondering if it will be reliable enough for the above.

People have rated the r34 smic to a maximum of 230kw~ atw but not many have mentioned about heatsoaking issues.

Hopefully there are a couple of r34 members on here with stock smic's pushing out 200kw with no probs?

Trying to decide wether i should install a intercooler waterspray

cheers

Think you should install a intercooler waterspray or go FMIC cuz i reckon even at 180kwrw the SMIC isn't doing such a great job for my GTT R34 especially in summer hot days...

Not sure if this thread has 'detailed' info to that level, dont have time to read it Pat.

Worth a try though

water/metho spray if needed, do a search on sydneykid and water spray

thanks for the info

any other r34 owners with similar experiences?

My car currently has 160kw and havent encountered any heatsoak yet, although not sure how long that will last once i go past 180kw

Why not install a temp probe and monitor it, no point installing a FMIC if there isnt enough gain

What about improving ventilation around the smic? Like creating more airflow through bumper and undertray mods. I think cutting some small holes in the cover behind the smic will help with heatsoak.

What about insulation (i.e. heat tape/wrap) to keep heat away from the smic?

I reckon these will, at the LEAST, slow heatsoak down. The water spray is good, but i reckon is more finicky.

reliability is fine - you wont have an issue with that youll just suffer increased intake temps

ive never really been a fan of the smics due to their location and lack of airflow

Not an R34 experience, but may be helpful...

I have an R34 SMIC in my R33, I have full 3" Turbo back exhaust, split dump pipe and Apexi Intake, high boost mod..

Not sure on the power, but at a guess the same as everyone else with these basic mods.

After a "spirited" drive, iv gotten home and thrown a hand on the back of the SMIC (i am missing the inner guard due to R34 SMIC girth and failed clips) just to see, and it is hot.. i mean HOT.

Normal driving on the open road with plenty of boost its similar. Its only cool when i dont give it stink.

One problem i can think of is that the Apexi intake is also very hot, IE sucking in hot air, as i dont have an airbox around it yet.

I dont feel any heatsoak issues or anything like that. It never hesitates or anything.

i got a 34smic on a rb20det 165rwkw and after 'you know' i've stopped,got out and touched both end tanks of the cooler and the hot side was warm to hot and the cool side is suprisingly cool. my experience.

if anyone is looking at getting rid of there 34 SMIC, please PM me as im keen to purchase one

I Ran into heat soak issues on the Dyno at 185rwkw on my R34 with the SMIC on a cooler day it might have been alright. Tuner had to leave it at that since it wasn't doing its job past 185kw went back with a FMIC and he tuned it to 210rwkw straight away.

In summer side mount is crap kills car power heaps.. Had one ditched it in winter, heading into summer because I couldnt handle it any more.. Fmic IMHO is alot better ..

If not use a alcohol or water spray over the cooler however it wont do much because it evaporates quite fast on a hot day. but will help!

Pat, just bite the bullet and install an FMIC with a return pipe that uses the stock hole, don't run a pod and you'll be street legal. and rig it up so you don't have to cut into the bumper support.

failing that, how about two SMIC's it'll drop your pressure a bit, but its still legal

[Rekin]

haha, yeah im thinking about buying a return pipe FMIC, but i dont want to lose my front electronic spoiler

[DECIM8]

Ive got a Trust HG polished setup, is very good and cant see any difference in lag times compared to my mates 33 with normal setup with the same cooler, unpolished tho :S

[Rekin]

If i get a FMIC then i'll have to remove my front spoiler

Spoiler > FMIC

Now with vids for people who dont know what im on about

i find my 34 SMIC made a difference when it comes too heat soak compared to the standard(r33 size) cooler. Also feels more responsive.

in same position with the electronic spoiler,thats why i'm currently using the 34smic,but will be going fmic with return pipe eventually.

ps. i like those blue driving lights.

[rev210]

heat soak on a dyno is due to the fan not directed to give it enough airflow, this doesn't happen on the road.

In short it's not a problem you should be fussed about. Getting traction and brakes are worth more stress and effort than this one on a stock turbo.
