I Was Wondering What Do You Guys Think Is A Better Fmic Kit For a 60-1 turbo set up.

the ssac/vr speed factory kit has been out for a while with many people proving it works, the punishment racing is just starting to get around, give it sometime before people start posting results for those.
right now it based on price and whats been around longer and proven, its the ssac/vr. for 14b/16g owners the punishment seems a bit better as it comes with jpipe and lower ic pipe for it. it actually comes with both pipes for both types of turbo installs. also seems to be installed much easier.
so which would handle a hx35 better?
oh ok.. cool.. yeah i guess it doesnt matter for me then. its cause i have both of them and want to get rid of one but i dont know which one.. going to sell the vrs one.. ty
between vrs and punishment intercooler which is better? dont include any other intercoolers, just these.

Neither.
No offense to any of them, but those cores are garbage. They will experience serious heat stroke after a few passes or a bit of spirited driving and not cool the air well.

It's no comparison, one offers what I would say is probably 2 to 4 times more surface for the air to touch and disipate it's heat on.
Have you run either kit? Or are you just spewing BS for the hell of it.
I run a punishment kit and it performs flawlessly. I've has a few track days where I had 15+ runs with minimal cool down time and my trap speeds NEVER varied due to heatsoak. Ive also driven 45+ miles to the race spots, raced (highway pulls) and drove home and the car never missed a beat.
I purchased a VRSF FMIC for my girlfriends 16G powered GS-T so we will see how it performs in the next few months.
Real world results > Theory.
Of course you will want to upgrade the core if you go past something like a 20g / 350-400 WHP.
Again, false, misinformed info.. A bunch of us have made over 500hp on the vrsf kit (or ssac kit) I myself have installed one for my 600+hp build. The vrsf/ssac core is no joke. Just because it is cheap doesn't mean it's junk. Everything in the ssac line is crap, except the 2g intercooler.
Who cares how much HP you are making on it when on the third pass you are getting double digit intake temperature spikes.
You truly are stupid. You have never used it nor logged with it so how in the hell do you know? I HAVE. GM IAT verified. Do you even know what a IAT is? Multiple 500hp track passes and this core is only hot maybe 5inches in.
The internal fins that you see in the ebay/china cores don't do s**t. The ones in the Garrett core that look all smashed up are offset on purpose to promote turbulence and to present more surface area to the tumbling air. The difference is huge. I've run several different IC designs and have posted temp performance as logged with an AIT sensor for most of them (a search should turn it up). On average you're looking at a 50-100 degree rise on a drag run with a cheaper core, and up to 50 degrees even on a smaller Garrett core, while a 4-5" Garrett core will pick up 0 degrees through the first 3 gears and about 10-15 total on a full drag run. Due to the large size they can soak up more heat and are effectively 100% efficient for at least the first half of the run on a medium sized turbo. The bigger the turbo and higher the boost the sooner the temp rise starts but you get the idea.
The Garrett cores are worth the price premium, especially on pump gas. Race gas will make a less effective IC usable from a knock standpoint, but you'll still pay in other ways. The cheap cores can also have a much higher pressure drop than the good cores, but I only have other people's logged data to go on, not my own. But, 4-5 psi is not uncommon even with a fairly large crappy core on larger turbos. When you're trying to max out a turbo, that will set you back.
Some of the best things you can do for pump gas performance are good intercoolers, big turbine sides, and more displacement.
