Anyone do a intercooler replacement and NOT add a tune?

From watching a few utube videos, a larger intercooler really is worth the investment. The difference in a multiple gear pull is temps in the 105F instead of 150F inside the intercooler.

I would want to keep the shutter system, so any i got would have to be thin enoough to allow that. Apparently the Vortech allows keeping the shutters.

The other issue for ME in particular would be stock tune.
i would like the benefit of a bigger intercooler, but would I be able to keep the stock tune? Is the size internal volume important issue in a 'tune'?
So any opinions on a 'fail' if I kept the stock tune? Or would it be OK.
Just curious.

Are you talking about increasing the diameter/flow of the charge pipe into the throttle or just installing an intercooler with a larger volume/cooling capacity?

If all you are doing is installing a larger volume intercooler and maintaining the same charge pipes you will not require a tune. The OEM/stock Tune will make adjustments for the intake air temperature as per normal.

Thanks. Yes it would only be the actual intercooler would be bigger to avoid (as much) heat soak.

The real shortcoming of the stock intercooler is it is hit by heat soak really fast. So before you hit the end of the quarter mile, it is barfing up lunch.

Otehrwise all the stock stuff seems fine to me.

Well if you are looking to ring a few tenths in the 1320. A tune would net you the best results.

Tune over IC for sure. You could also unplug the grill shutter in open position.

Personally I'd agree to disagree on this, but a tune should be the last thing you do to a car, or at least after the intercooler and other upgrades.

Intercooler before tune is the way to go if you were to modify the car at all because what good does increasing the boost which increases heat if you can only use it in even shorter bursts than stock due to the increased heat?

When, in the streets, did you ever heat soaked your stock intercooler? I drove in 30-40c all summer (86-104f) and never heat soaked my ST. I had a good tuner, colder spark plugs and a FRPP CAI.

That would be different if he is tracking the car.

After just one or two pulls up to speed you would have experienced heat soak even on the streets, just two or three acceleration runs up to speed while holding onto boost in lower gears has according to other ST owners who were data logging shown increases from just a few degrees over ambient to over 100F over ambient quite quickly.

However for most normal driving circumstances you would require neither a tune nor a better intercooler as you're not often in heavy enough boost to require this.

I don't mean to hijack the O.P.'s thread with discussions of the merits of an intercooler v.s. a tune, or the order of operations of installing one or the other.

Colder range of spark plugs transfer heat more readily into the head and away from the combustion chamber to compensate slightly for increased cylinder temperatures and pressures, but this alone does not affect intercooler performance.

I've driven on a road course with my car when it was stock, and even then a bigger issue is as usual going to be the brakes depending on the course, although with the upgraded brakes on the cars at the Octane Academy it was a lot of fun.

The discussion of tune vs intercooler is OK. It still is discussing the merits of what I asked.
I understand the idea of a tune. (plus the pressure due to tuners on board sellingtheir product)
But I am somewhat resistant to a tune.. mainy due to my ineptness at updating computer stuff. Having ruined motherboards trying to update them.. LOL So I and 'tune' should not be in the same room.
Anyway an intercooler would be my favorite thng to do.

The only other thing I would like to do is insulate the intake from the air filter box to the Turbo, (and maybe the pipe from the intercooler to the intake.)

An acceleration in 4th gear in a ST gets you over 120 mph. At this speed, in the streets, you are going fast enough and by the time you slow down, the Stock IC (with always open Active grill shutter via a tune) is back to almost ambiant.

But like you said, We need to stop highjacking the OP.
