Phenolic thermal spacer for PD

Well nuts. Thanks for clarifying, that would've been my preference. Next time

What ? After a hot soak I might see 20 over , but after a minute or two down to 3 or so .........Oh wait I live in the centri world .

Not being funny but is there such a thing as IAT2 for centrifugal SCs, a way to measure the air temp after the compressor at or near the intake manifold? I've never really bothered to learn about it.

Iat is measured at the maf , in my set up that would be the right tank of the cac . Cold side if you will . Since it is an air to air cooler , the charge is cooled . With that said , no centris don't have an iat 2 . Basically iat would be iat in your set up .

If the MAF is located after the blower it will be reading the charge temp of the heated air. You don't want to have it before the blower because it's not accurate. Even with an IC those temps can get toasty.

Adding to this.

Just installed spacers last night from FIinterchiller, 20-25* over ambient with normal driving, still pulling in 50-60 over ambient with wot.

Iat2 were sitting as high as 160* at the end of the pull. Wish Roush would’ve made the cooking better.

50-60 degrees over ambient is crazy. Ouch…!

Are you 100% sure there are no air pockets in the IC system…?

Didn't do anything really? That's totally opposite of what everyone else has experienced. Umm

probably had the car out long enough where anything under the hood will get heat soaked anyway

Potentially, we just got the car done and didn’t have a good enough vacuum system for the entire cooling system so we couldn’t pull vacuum.

I did notice a difference, just not as good as everyone else’s.

Maybe 1 hour. It was 100 today so your probably right. I do notice a difference though.

Honestly time will tell, once the system gets fully burped and all that. I do notice a difference though. I had high hopes it was as good as everyone says it is.

That's good..

True. 100* is hot no matter what cooling mods you have. You drive around with dry ice in the intercooler and still see some high temps. lol

Keep us updated.. Thanks

Something doesn't seem right with your setup. What pulley and blower? What pump? Anything still touching that would effectively bypass the spacers?

Have done 2-3 hours city driving in 105 degree temps or 2--3 hours highway followed by hour of city. Results have always been the same. Even extended idle (45 mins-1 hr)with ac on in 95+ temps and parked in parking lot. All the fluid temps/ under hood temps stabilize pretty quickly once engines up to temp.

Pulled somewhat recent long idle log, mid 90's ambient. 35 minutes no movement and ac on. iat rose to 147, iat2 only 127.

Yeah, wasn't a super good metric to see how bad the heat soak gets under normal operating temps, as these temps arent normal.

I do want to add, other than the Roush Phase 2, it is a completely STOCK cooling system not even water wetter or a 170 Thermostat. My line of thought is that now that the spacers are added, any small change to the cooling system should be twice as good now that the Roush Blower isn't metal to metal on the heads. Next mods are the thermostat + temp blanket for the underside of the Roush blower and a 70/30 mix with water wetter to see where the car stands.

EDIT: This is for a 18+ mustang gt which have notorious heating issues due to the outdated Roush Intercooler brick ON the blower. 15-17 Generally don't have this issue, but spacers work the same on the 2nd gen.

After my FI interchiller setup, when I mash the IAT2 goes DOWN not up. When cruising and the blowe is largely in bypass, the IAT2's still hover just above ambient (once it's fully heat soaked) but once I mash the go lever, I can watch the IAT2's start dropping........quickly.

It's a weird phenomenon that I've tried to make sense of, but I guess with the motor at low load, the air charge doesn't have enough density or dwell time to get fully cooled as it flies by the intercooler core. Once the air load goes higher and boost is created, it must somehow greatly improve the thermal transfer inside the intercooler brick.

I have yet to install a temp sensor on my IC system so to have all the information that's probably a next step at some point. I just don't have any external gauges outside of boost gauge anymore (Ngauge is gone) so I'm not sure where I'd send the output and I don't want to add to the instrumentation.

Point is, I'm seeing IAT2 drop under a pull, not rise.

FYI that happens on my 3.0L Gen5 Whipple with no chiller. IAT2 is lower at the end of the quarter mile than when I started. Key is proper brick size and the Whipple delivers in spades.

ahh.. You have a 2018 2650... That could be why the temps are not so drastic. Like you said those do have heat soaking problems.
