Looking for heat soak

After reading about what a difference a bigger intercooler makes, I am considering it as my next upgrade. However, I am a little confused on exactly how and when heat soak occurs.

Last night - 90 degree weather, driving home from work and I am getting into full boost on the highway at about 65 mph in 4th gear, going up to 90 or so. I do this repeatedly and it boosts fine each time. If I had heat soak would the boost gauge still go into the red, or would I just experience less pull? I have stock gauges only, I know I need to upgrade those...

Is there differences between the stock 9-3, SE and viggen intercoolers?

How hard do you have to be driving the car to experience heat soak? Does it occur during WOT through multiple gears?

Thanks for any info.

You will feel the car not pulling as hard. The stock gauge measures airflow only. The stock 9-3 IC is shit, SE and Viggen are the same, and are much better. But they still suck.

If you want the biggest drop in IC, its the Forge. ETS requires a little modifications.

legit are you speaking from experience?? Some people do not need to do any modifications to fit the ETS

I had the "Viggen" (cross-flow) IC in my 9-3 (came stock on all T7 9-3s, as I recall), and recently upgraded to the Forge. HUGE difference. Highly recommended.

I ran the Forge in my Viggen and it was great.

Huge difference over stock.

you have a sqr stage 4 tune but no IC to go with it?!?!?
why would you go through putting in a bigger turbo with no IC?]


you want the coldest air you can get in your engine, so on a turbo car the air goes throgh the turbo and gets compressed whick makes it hotter than when it came into the intake. a intercooler makes the air cool down by having th hot air go through it as cooler air passes over the intercooler cooling it down. so heat soak is when the intercooler is to small or poorly made or has not enough air flow and does not cool enough, this will make the air going into the engine hotter which makes the exhaust hotter which makes the turbo hotter which makes the air going into the intercooler hotter and it just goes around and around.

look around on ebay for some intercoolers, you need to make most of them fit but it might save you some cash over a forge or mp one.

Go on ebay and look for one. Drop in or not, it's not impossible to stick in. If you're running stage 4, then you'll definitely need something. I felt heat soak with the T25 even on slightly cool days. I installed my intercooler a little while back..it's a 22x8x3.5 and I think you can get it off of ebay for $100 after the recent price drop. Plus piping, it's a pretty good deal. Difference is noticed immediately.

I didn't put in the bigger turbo, I had the viggen turbo already in the car as it is an SE. At the time I got the tune, I had just started researching tuning the car and Automotion did not recommend a bigger intercooler for Stage 4. They have since added the intercooler as a hardware requirement to their web page. The Forge seems pricey at $500, has anyone on here installed the Godspeed from eBay at $120?

I have a mp, easy install, works good for me, no problem on track or autocrossing with it. It's a little smaller then the ets, but I dont need anything bigger...yet.

Thanks, looks nice.

That was me tonight on Rt 95 north in MA. Was with you for awhile until that minivan with the quick lane change almost made you run off the road!

Your exhaust was loud as you blew by me!

yeah that guy seriously pissed me off...i didn't realize how fast he was closing from behind until it was too late and i had nowhere left to go but squeeze in behind you...i'm sorry!!! i get so aggravated when people drive like assholes but ironically it makes ME want to drive like an asshole, mostly to chase them down and ask them what their $#%ing issue is!!!!
i gave up on him soon after when i realized he was probably going to kill someone. i think he was doing about 110.

thanks for the thumbs up and the exhaust compliment ... its a full 3" with a sport cat, no center resonator, and a magnaflow 14828 race muffler. car is running like crap right now though, misfiring, hesitating, stalling...
