Alright looking to c how ur iats r with either of these intercoolers at or around 700whp..reason being i have a pte 750 n im starting to wonder now if will actually b enough. Thanks for replies...1 2 3 go

 

Precisions are already heat soaked by 650whp, and almost blistering to touch. I have no feedback with the Vibrant 875hp version.

 

You need to provide more details.... What turbo, what boost, what exhaust manifold etc.

There are many variables that affect your IC and what rating should be used. IE front bumper type, fin density, climate, hp, etc.
1, 2, 3, go.

 

my setup is 84.5x89 9.5-1cr gsr
Itr head with pro 1s
Afi top mount
precision 6265
Stock eg front bumper for now, gonna go with a 3pc front later on
im hoping for around 700 whp around 30 psi
Were basically gonna try n c what I can make with this turbo.
I got the 750 up for sale right now.. As of right now I don't have a job so my only option as to upgrade would b the vibrant because I gotta get a new one for around the same as what I get for the 750, otherwise there's no doubt I would just pick up a garret core.
But if I can't get rid of the 750 I plan to build a duct to draw the air across the entire intercooler to hopefully increase its efficiency.

 

That IC will be fine. Garrett underrates their cores anyways.

 

I don't have a garrett...

 

anybody have experience with the treadstone tr1245?

 

Precision uses Garrett cores unless you have one that's brand new. Just recently Precision started using different cores.

 

Oh I wasn't aware of that.. It was purchased around 6 months mayb more ago so it should have the Garrett then I would assume

 

They haven't used Garrett cores in YEARS, Chris.... YEARS..

 

Nope. you don't. Unless you got it back in 2005

 

lol ok thanks for clearing that up... Anybody with experience with any of these please chime in! Theshodan how much do u think building a duct will improve the temp on the 750 while moving?

 

Won't matter. The intercooler itself will heatsoak as it will no longer have the ability to exchange hot pressurized air from the compressor housing discharge to cooler air that would go into the throttle body and ultimately the combustion chamber.

Ambient temps won't matter, its the fact that your IATs will be through the roof with that intercooler by that time. Unlike the Garrett cores that are underrated for their capability, Precision cores are rated at the crank and are therefore a bit overrated for what they can do when reaching that power level. You're better off with an ETS, Garrett or Bell Intercooler core.

You want to get that power.. pay the piper and get the REAL equipment.

 

**** I wouldn't mind "paying the piper" I get that 100% and I don't mind one bit I understand u "gotta pay to play" but I just don't have the money right now.. if I did I would(honestly Theshodan- if u wanna give me a garrett 950 core for whatever I get for the pte 750 i will take it n ill take care of the rest... lol)... anybody else wanna tell me they're experience with either of the three intercoolers present especially the vibrant 875?!...im not even opposed to a cryo2(or any other options for that matter) to cool in charge temp...

 

Unfortunately, I don't have much experience with the larger Vibrant intercoolers other than in Evolutions S15s, and some other makes for street or circuit, which don't run as high as 700whp.

 

Sounds like you need to get a 24x12x3.5 garrett core intercooler.

 

Wow I just found a 24x12x3.8 for cheap! Someone needs to buy my 750!

 

That's true.... I've been at this for too long.... it seems like just yesterday. lol

 

Yes. We are old..

 

Nobody else that has experience with either of these?

 

It could be old stock, post a pic of it... A Garrett core is simple to ID

Yea it seems like a lot things were just yesterday *sigh*

How do u Id a Garrett core ?

 

Very simple, here are some pics

Face of a Garrett core



Face detail, showing fin design and density.. Also notice that each pressurized air passage extrusion has a "lip" at the top and bottom of each one (ETS cores also have this lip but are not Garrett cores but are of a similar design)



Looking inside an endtank of a Garrett core, shows fin design and density. Note the small bands of tig welds, Garret does this on almost all of their cores)



Another angle of a Garrett core with no endtanks. Here you can see the tig welds I was talking about, normally Garrett does this at the top and bottom of the pressure side of the core, or wherever the inlet of the endtank will be.

You can also see the lips on the extrusions I was mentioning.

You can also see the complete construction of the core (ebay cores dont have that point on the extrusion of the pressure side fins) showing the design differences in ambient and pressure side fins, as well as fin density)



Full view of the pressure side of the core



Hope this helps.

I think after Precision lost their Garrett supply contract, once they used up all of their remaining stock they went to china/ebay cores... at least this is what I have been told. Unless they went with a company like ETS...

Precision has started using proprietary materials in most of their products but IIRC they don't have the ability to produce their own intercooler cores, at least not yet, if ever...

 

Thanks for that man. Learn something new everyday!
