We're a huge supporter of Precision products as well as their intercoolers. I had another intercooler come in so I had a chance to take a pic showing the fin density of each. I just wanted to show that not all bar and plate intercoolers are the same. Precision core have a higher fin density which does make a difference in cooling the intake charge.

This is a Precision 750hp AS1026 core looking in from the end tank


This is a competitor's core used by many shops around the country in multiple different markets. These cores are cheaper than precision or garret cores and while they still work well, they are not the same







*EDIT
more info from ETS

The first thing you want to check out is the fin pack design. An offset and staggered fin design will be your best bet in dissipating heat. The straight through fin design will pass the air right through like a tunnel, the offset and staggered fin pack breaks up the air molecules and forces the air to come in contact with multiple fins creating a denser charge air.

Precision intercoolers always been top notch... you can get exactly the power they are rated for out of them with no issues...

Cheaper intercoolers have always had to up the size to compensate...

 

Been using precision cooler for several years nothing bad to say about it.

Though now im using a garrett core due to size.

 

be nice to see some air temps going in and out in a controlled environment and boost pressures in and out, to compare rather than pics of "fin density"

 

 

So please conduct this test and post the results up.

 

I'm not the one selling precision products or posting pics of stuff and why it's better. So please conduct this test and post the results up.

 

Is the "competitor's" core an ETS core?

 

From ETS:

The next would be the intercooler core design. We prefer a bar and plate core. This core does an amazing job at being efficient.


** ETS Core VS Garrett (We do something a little different here by changing the size of the charge row to give us more heat transfer plates. If we have an extra 4 charge rows over the competitor core in the same area we get 8 extra heat transfer plates. This is the top and bottom plate of the charge row. By doing this we can loosen up the internal charge rows which gives us less pressure drop and more external heat transfer area.

Here is a picture of the Garrett core that we cut in half to make a smaller SRT-4 intercooler. The internal results of the Garrett core were a bit disturbing. The core doesn't look like it would flow too well.

You can argue that a Garrett Intercooler doesn't look like it would flow well, but you can't argue with the FACT that they work damn good.

 

Good Info ......

 

Yea I was thinking the same thing

-Steve

 

anybody use the Bell intercooler cores curious how they look and work

 

No it is not

-Steve

 

Nice comparison, I've always been a fan of the precision intercoolers(I currently have the 600hp version)

A little OT, but I am wondering if anybody has pusted the 750hp version much past the advertised rating before the IAT's got out of hand?

 

we have ; ) but not far.
