How much does it help? Not much at all. After 2-3 laps, it runs about 35F over ambient. No better than stock. Maybe it drops faster in temp. I can't tell, and it ends up just being extra weight. The plus is that I don't have to worry about cracking an end tank, but the extra weight sucks.

 

i know i was able to go up to 16* of timing from 14*, even in my florida hot and humid weather. temps seem to be the same though.

 

My car loved the zzp intercooler. it was the full size though. my car hated boost and timing before i put it on.

 

Have you tested any others units to compare? How about full size unit?

Hahn claims big drop using their unit

 

After 3 laps on the stock unit what were the temps? I noticed about 10* temp drop during tuning logs after install

 

Okay, look folks, I'm not talking about short little pulls or drag or whatever. I'm talking about on a race track, lap after lap. I'm seeing temps averaging about ambient + 35F, which is in the ballpark of the stock unit. What I can't tell, is how quickly it falls once I'm done (does it matter?).

 

yea stock isn't bad for cooling just plastic endtanks are retarded..

 

stock flows great... only problem is the end tanks in the long run.

 

Nice little review man. I trust you cause I watched almost all your videos of you ripping the track. I have a different intercooler but I can tell you It's the same with me too. Not much difference than stock to be honest. Just good assurance that the ends wont blow!

 

For what your doing maybe not but for the street/drag racer its ability to shed the heat in between runs is important. What psi are you running the k04 at? This may be the main source of the heat. Bigger turbo at a more efficient boost range would drop temps.

 

Sounds like you will want my one of a kind radiator when its available lol. I really want them to make it available so I can watch the stupid install video...

 

knowing wangspeed hes not running the turbo past its efficency range so i doubt its contributing to a large heat source. hes probablly spiking around 24 and dropping back a couple psi... anything past that blows hot air and is pointless to me.

 

Pretty close. I spike somewhere around 22-23, depending on the situation, and it drops to 20-21 and trails off sharply after 5500, like the stock tune.

 

yaeh theres no need to go any higher. we did some testing where we spiked to 26psi and let it fall back to 23 but it didnt yield much at all so we spike to 24psi now and fall back to 21-22ish both on the cobalt and the solstice. probablly going to throw one of our intercoolers in for some road corse abuse. guys that run it doing highway pulls and have big turbos all seem to love it so far and the heat extraction coating does its job. our solstice one proved good results but we cant run them due to class regulations. i had our race version in and it did well but we'll see how the street one works in the future before i get to racing a class with it and the stock turbo. dont see why it wont yield great results aswell since its VERY similar to the solstice stuff.

 

I just wanted the metal IC so I could stop breaking endtanks. That, and it's cheaper than a stock IC.

 

Yeah, pull after pull repeatedly on any intercooler will heatsoak the car. Its just a matter of how long it will take to reach those temps and if you give it a break how quick it will drop. You're also dealing with underhood temps. So maybe you should try wrapping your hotside or getting it ceramic coated.

 

I'm a bit confused. The stock IC is metal so what do you mean?

Edit: I'm guessing you're referring to the plastic end tanks on the stock IC. Is there any way to replace them with metal ones that will fit the OEM IC?

 

you can but we looked into this before and its not cost effective to do it production wise but it can be done.

 

That's about all you're going to get...that and it probably takes a smidge longer before you get to the same temps as you did before.

Longer to warm up, quicker to cool down.

On the track, have you tried taking out the lower grill?

I wouldn't recommend daily driving like that but it does help, but eventually you'll get to the same temps. There's really no way to completely lower temps without getting a larger turbo or bumped the boost down a little.

 

im pretty sure any of the aftermarket intercoolers would give u similar results, if ur going around a track lap after lap, ud probably need some other cooling system to help keep cool, like meth or ic sprayer or something

 

The surface area of that zzp intercooler isn't exactly large by any means, you'll need something much bigger if you want to do any type of racing, its only ideal for quick pulls on the street or a 1/4 mile.

 

I've posted the same basic thing in the past but no one seemed to believe me. Granted I'm not pushing the turbo nearly as hard as wang is around a track, but even in a "long" 3rd to 4th gear pull (starting at 3k in 3rd) the iat2's really aren't much better in the zzp ic vs the stock ic. I've seen some crazy claims by others on here a while back that claimed to have seen iat2's BELOW ambien at wot WITHOUT a sprayer bar or meth, which is quite franky just flat out rediculous no matter how big the ic. Like others have said, it's well worth the upgrade just to simply get rid of the plastic end tanks though.

 

and good luck with that. intercooler sprayers are prohibited in most road racing sanctioning bodies and methonal injection has its problems. only thing its good for in the DI cars is helping keep the valves clean imho.

 

In the winter it's possible.

 

pack ice in the intake lol
