Finally getting hot after swapping intercooler.

I wish I kept my stock ECS unit. In 95F weather already seeing 235+ and climbing. ECS intercooler was always 120F over ambient, now it doesn't even come close to staying cool.

So lesson learned, if you want a cool running car, don't run a huge air to air. May have to have a summer and winter intercooler.

Nice update. Refreshing to see someone give both sides, rather than just saying what they got is the greatest ever.

agree i didn't expect you to run into that big of a heating issue tbh

Unreal

Not even hot yet. Sucks

Coolant is fresh, no leaks, no issues. Condenser is actually cleaned out and better. Only part that changed is the FMIC. Went from running great to crap.

75+ car still hovers 215-220.

both cores equal 1500 cfm. I also got sick of having everything in front of the radiator.

this is super helpful info as I was considering going to a bigger intercooler. I don't think I will now after hearing this. surprised it created that big of an issue.

any tuning tricks you can throw at it to help a little? more timing on the idle map or more cruise timing? bigger oil cooler in fog light section? i have no idea but that sucks.

Unreal

Well was perfect before big FMIC, now it sucks. So pretty sure you can say a huge FMIC blocking everything causes issues.

I'll just drive my other 4 cars during the super hot time, or put a tiny or just no-intercooler during hot weather. There is no races May/June/July/August so bypassing it to drive it daily wouldn't be a big deal. Not like any racing in 110+ happens.

Yeah mine was reading 200-220 with smaller A2A core but was right up against condenser. Moved it about 2.5" forward temp went to 175-185. New Big Bell A2A intercooler temp stayed about the same with my AL block. Now an LSX block they went up a little 178-190 But still not bad for an Iron block in Texas heat with A/C running. Another thing we did to a few cars was try to make sure the intercooler is at the same angle as the radiator/condenser to make sure it was as least restrictive as possible. Worked on all the cars, temps dropped. Not sure which one is more important the air gap or the angle, but its worked pretty well for me and a few friends FWIW. GL!

Unreal

Yah, no real room to move it farther forward. I think that is why the old one cooled good. It had a solid 2" gap or so between condensor and FMIC. I went with a way thicker core that filled that gap, so not only is that gone, but the fan has to suck through way more.

Ohh well.

Time for D3 Fans

Unreal

Nope. Fan setup I have works just as well, and fits. Plus that would require full size radiator, and a ton of fab work.

Its what I recommend to people, but I'm not dropping $2k+ at this point to go down that route. I rather swap a smaller FMIC back on for 3 months out of the year.

Unreal

This is a perfect example of trade offs needed for a high HP car.

Gained 2mph in 1/2 mile, and lower IATs, but now have heating issues. So was the $1200 for an intercooler worth it? If it was a full out race car chasing records, yes. If it is a primary street car, I would stick with the stock ECS unit that makes 1100+ with ease and cools fine.

You either accept trade offs, or spend a ton of money engineering solutions. Could I fab up some crazy dual core setup, plumb in a secondary radiator, etc etc, yep. Do I want to drop thousands just to sit in traffic on 100+ days with AC on, not really.

If anything, I may pull the intercooler for hot months. Just bypass it. Sounds like a decent option.

This is running e85 with meth injection right?

DOUG @ ECS

You summed that up pretty well. We have ZO6's with our large intercooler not running hot in the summer with the AC on, but we put as much time and effort into making that happen as we did to install the supercharger.

gameover4

what do you guys consider hot? i live in south louisiana so i know all about the heat but on hot days 80/85+ much less the upper 90s days. my car with ac in traffic will get 216-225ish. when do you guys think it begin affecting car and/or head gaskets.

ysb02

Guys run up into the 230-240s here on the track which is a much more harsh environment than street driving. I'd probably get worried and turn on the heater ~235.

Unreal

I would cut a/c at 230-235ish. Seen 240 before and don't want to do that again.

Sad part is last summer ran 120F over ambient no matter what. 120 outside I may see 240.

Now I'm seeing 130-140 over ambient. Its only mid 90s in AZ right, which means when it is 115 outside no way car is remaining cool.

Ohh well, good thing I have a mustang.

Unreal

yes, or do be exact, flex fuel.

Meth isn't on at idle or around town, so meth doesn't matter.

I'm not doing 3rd/4th gear pulls and getting into 5k+rpm where meth is on when it is so freaking hot out.

No idea what E blend is in the car right now, but been between e54 and E10 for past 3-4 weeks. Doesn't make much of a difference.

I'm sorry to read this for you but it's a wealth of info for the rest of us.

As a newb to your platform, what would be recommended to keep an 08 Procharged D1SC w/ meth that comes on when in boost, during traffic in the summer heat of texas, with the ac on?

Mods are:
D1SC
Dallas Performance Big Mouth Blower Air Filter Kit
ECS Boost a Pump Kit
TiAl 50mm Q Blow Off Valve
Alky Control Methanol dual nozzle kit
Dallas Performance D6 Blower Cam
Brian Tooley GM LS9 Springs, Pushrods, Valve Stems, Titanium Retainers
FIC 1000cc Fuel Injectors
GM 160 thermostat
American Racing 1 7/8 Longtube Headers
C6 Z06 Modded Exhaust
NGK Red Wires and BR7 Spark Plugs

Unreal

Biggest radiator that fits
Biggest fans that fit
Biggest external coolers that fit
Custom shrouds
Ceramic coat everything
Vented hood
E85
etc etc etc

Been there, done all that. I easily got $4k-5k just into cooling stuff.
