I've heard the big ebay intercoolers are working pretty good for people, but there's quite a few different brands in the same size, is this the one that most of you use with good success, or is it a different one? Thanks for any help!

 

Yes, that's the one.

 

Cool, thanks man!

 

Ive used two with success

 

same... i use it

 

whats up devon, has the turbo car coming? stop by the shop sometime.

 

How much hp can this support?

 

Are these intercoolers mainly being used for turbos or superchargers too?

 

Works good (I run one) but the higher dollar ones do perform better. I'm getting to the point where if I try to make more than 13# with my little .96 AR the IAT's really get up there (only on the track).

 

I don't see why it'd matter.

To the OP - here's a pic of that intercooler installed on my Camaro using a bracket I fabricated.

 

^^ ya done good son. ya done good

 

Nice!

 

not to dig too hard lol but anyone try the EMUSA 31x13x3 with 3"in/3"out bar and plate? design. bought this one. waiting for it to come in.
anyone know how much pressure drop across it, with everything working right?

I went with the Treadstone TR1235 intercooler 12.5h x 22l x 3.5w (core size), overall length is 30" with 3" inlet/outlet. Treadstone claims to have less than 1.5psi pressure drop at max flow, a 1142 CFM flow rate and 760hp efficient but good up to 1,000hp. The 4.5" core is suppose to have 1.5psi drop, a 1469 CFM flow rate and 860hp efficient.

The reason I chose this intercooler is because I didn't want to spend $700-$1,000 on an intercooler, and I didn't want to go the ebay route because there's just too many "ebay intercoolers" to really know which ones are decent. The Treadstone is a little more expensive than the ebay intercooler, but is a very nicely built product. Its a bar and plate design w/ dense fins and a divided inlet/outlet to route air to the top of the intercooler where most other intercoolers don't. I think this is an awesome addition to the design, allowing more surface area of the intercooler to be used by dispersing the airflow more efficiently through the entire core instead of the only the lower section to cool.

I'm sure the ebay Chinese bar & plate intercoolers may have low pressure drop and may do fine with one or two pulls, but the cores just don't have enough fin density in most of these designs IMO to keep them very efficient under constant loading. If I'm going to hang a 30 lb heat exchanger on the front end of my car and partially block the flow to my radiator, it sure as heck better do something!!!



Divider is on inlet and outlet of the endtanks. I love this feature!




AWE tuning also has a similar end tank design showing how the use of a diverter covers more surface area to cool the airflow even more.


Notice the fin density, fin staggering, and methods to trip vortices the fins are slit and bent outwards into the flow to further assist in cooling.


Here is a pic of a ebay bar & plate core. This core may have little if any pressure drop, but can't be good for IATs. Seems like the airflow would move to quickly through it without cooling the charged air effieciently. IMO, this may be good for low boost applications and highway driving, but I don't think it would be good for hot lapping at the track.


Here is the Treadstone TR1235 on my G8 using the Procharger 3 core intercooler brackets which happen to fit perfectly making a clean install; didn't have to make a custom bracket like I thought I would. I was initally going to go with the 4.5" core because the 1469 CFM rating was close to the max 1500 CFM rating of the F-1D, but I wasn't sure if it would fit behind the crash bar without cutting it. Now that I know it will fit, I may step up to the larger 4.5" core around tax time.

 

I have a smaller intercoller that I use, it is the best intercooler for least money. It is very nice core and fins inside looks like the same a spearco ones. Treadstone is a good.

 

that little guy will support 1000 easily and with it in my front bumper on my t/a my IAT's never get 8-10* over ambient temp

 

I have a Treadstone TRV25, for sale if you ae interested. It's brand new and i'll give you a hell of a deal on it. I'm gonna go A2W now. Here's the link: http://www.treadstoneperformance.com...cooler++1000HP
Flows 1492cfm and rated to 1000hp.

 

i gotta admint i do like treadstons endtank dividers. thats a really good design to help spread the air out across the whole intercooler. I went with the largest intercooler i could find on ebay and happen to find EMUSA's 31x13x3 for $80 shipped so ya, definitly isnt too bad for the price especailly being a bar and plate. on my low boost desires, this thing will do just fine

 

i use one of the ebay 31x12x4. at the end of a run my iats get into the low 150s.

 

Same unit I've got on my car. Great IAT's after a pass like you're running! =) Can't beat it for the $.
