Modified Precision 750, Which is a Garrett Core I believe.

Picked this thing up for $250 lol...


Hoping to push more then 800hp through it.

 

Precision 750hp are not Garrett or Spearco cores. They have another source. They rate their intercoolers to the crank.

 

What does Honda-tech think of my intercooler set-up for 250-300 hp d16? This is mock up only in the photo.

 

sorry to nick, but it just suck out at me...
Your ground cable could better be placed else where. And also what's with the throttle cable, looks like there's no slack in it at all.


PTE FMIC are solid. although when your shooting for that much power, I would spend extra money on a bigger or custom FMIC.

that's plenty fine. Although I'm curious why you choose that "style" fmic, it just makes making the pipes more complicated than required.
If you needed/preferred both pipes on same end, I would of went with something like this.

Well there sure are alot of misleading company/websites/forums out there with that information lol... Seriously Google Precision Intercooler core and see what pops up. A bunch of places saying there using Garrett cores. Pretty sure I remember Precision saying on there website a few years back, they were utilizing "High Quality Garrett Cores".

I know I know. This picture was the first day this car ran, obviously i'm using a Beer Bottle as a Coolant Reservoir to. The next day the motor was sitting in my Kitchen Big changes next year if the wallet/freetime doesn't bite my **** off first

 

That would be an AWEFUL FMIC choice for me. They can't even edit there damn Advertisment correctly

FYI, there is plenty of Slack in my Throttle Cable! It's just the angle of the picture!

 

that intercooler in the link wasn't for you pal. lol
No worries keep up the solid work sir.

 

Only saw a few post about Vibrant intercoolers and cores. I plan on using a Vibrant 25" W x 12" H x 3 1/2" T core. Looking to make ~700+whp. We will be making a full back-door intercooler out of this core.

 

If this is True, there are multiple websites selling precision intercoolers stating they are garrett cores. Fyi

http://www.titanmotorsports.com/prin.html

Not saying it isnt true, but its advertised this way on alot of websites selling them

"Precision's line of Air-to-Air intercoolers are perfect for street driven performance. Each intercooler features a high density Garrett core with bar & plate construction which allows each intercooler to better function as a heat sink -- which is a big advantage in stop and go traffic."

 

The compressor faces the passenger side and I did not want to have the hot pipe going over the downpipe, there is one U bend to the compressor on the hot side then a typical back door style cold side. Wouldn't that intercooler you showed me have more boost loss because of the longer rows? I was of the impression that a larger number of shorter rows was a more ideal design.

 

That was a few years back. Precision stopped using those cores back in 2006. Gotta stop Googling so much and ask those that know. Its confusing because you're looking at old information (not seeing the dates) and believing that it is current information.

 

You mean pressure drop. And to answer that question, it depends upon the number of rows per plate and how they're designed to determine if its a large enough pressure drop. Its not that big a deal, you'd just need to increase boost by 1-2psi or so to recover from that drop. You'd barely notice a thing.

 

But then why would the Treadstone intercooler be a better intercooler for the application since the packaging concerns have already been figured out? Not that I'm going to change it, since the intercooler and piping was only $55, but because I am curious from a technical design standpoint.

 

No one said anything about being better or worse for a particular package (which you haven't stated other than show a picture of a mockup on an RSX). The fins, rows, and plates are of a different (less robust) material than the Garrett, Bell, or even Mishimoto counterparts. That's why it was so much less expensive.

There's a difference between working, and working well. See Page 2-3 on the technical aspects that we all discussed.

 

since we are on about intercoolers. tell me, am i insane to consider an air-to-water intercooler for a 350HP car simply because i do not want to run too much piping and have an advert hanging under the bumper?

 

That's because Titan Motorsports and many other online vendors simply took text and images from Precision's old website (When they did use Garrett cores)and just decided not to change them to the newer content on Precision's current website. Even the part numbers from what Precision used (I.e. the AS1021, AS1025, and AS1026) have changed to their new series from after 2008

Even on Precision's own website there is an omission that they use Garrett cores.. They actually don't. For example, they now use a PIN053-1015 to designate their 750hp intercoolers..

Noted here:

Please do get confused with my message here. I'm not saying as though that not using a Garrett core is a bad thing; there are lots of other companies that use materials that are very good and are efficient for most of our everyday and race needs. This is just to simply clear the air that Precision uses their own private label company and processes for their cores and endtanks, that's all.

So I do have a Garrett Core, being that this Intercooler has been sitting for the past 7years (between two owners)... I finaly gave it a 1st run last month

However since then Garrett has changed/improved there design if i'm not mistaken?

 

IIRC, it's just more expensive & parts over your typical fmic kit.
Will it be beneficial, sure... but $/whp gain won't be easily justified by most.
So it's up to you pal.

 

Yeah When you first mentioned it i 100% believed you. I knew of anyone you would be the one to know this stuff. Simply wanted to provide an example since i could understand why they would think that. Thanks for clearing it up. Im sure precision still makes a nice intercooler i dont think anyone is doubting that. Although its unfortunate they do not have Garrett cores since they are priced decent. I myself use a PWR intercooler. its small but does the job for my power level. It was rated at 475 WHP and its right where im at. Plus didnt have to cut my radiator support at a 6.5 " height.

 

That's correct. They have now added a 3rd Row of louvered fins between the main plates, as opposed to the one from 2009 in which they only had two rows (A front and back set)

I compared my Garrett core from 2009/2010 to the newer one I'm going to use and there was a significant difference in the number of rows.

 

price comparison the A/W system, which includes the intercooler, the heat exchange and the pump with the fittings and a fan from just-intercoolers costs about the same as the Garrett unit from ATP. the piping is negligible in cost and fabrication.
what have anyone heard about those systems?

 

Yes. And it can be a lot of extra work instead of additional piping. Most still use another reservoir to have cool water or even ice to work. It's really best used in a drag only situation and doesn't have much an advantage on the street, despite how great it appears to be on paper.

As stated , only you can determine if it's worth the additional cost and install

 

To end the precision core debate...

A FEW YEARS AGO Garrett stopped supplying precision with everything Garrett due to their improper 3rd party modifications to their parts that caued failure issues (amongst other things but that was a big issue)

A lot of precision retailers have not changed their site to reflect this. If you buy a new precision intercooler that does have a Garrett core then it's a unit that's been sitting on a shelf.

Precision now uses the typical china/eBay core we've all come to know and hate

 

Hey nice intercoolers guys !
I'm running a small godspeed FMIC on my eg
And it has been doing great so far
And it's POLISHED :D lol

 

The ebay intercoolers are great for relatively low boost/compressor outlet temp builds.. once you get into high boost and high turbo outlet temps the core design causes a huge pressure drop and intercooler outlet temps skyrocket... also the "standard" big 12" tall core unit has the worst endtank design with the inlet/outlet being at the very bottom (or top depending how you mounted it) which caused all of the charge air to go through a very small portion of the overall core (someone did digital fluid analysis on the design and it literally shoved 80% of the charge through the bottom 3-4" of the core, I'll try to find that info again)

So when you have a fairly low boost/airflow setup the core is decent

My sr20 s13 had the big typical ebay "standard" and at 14psi on the stock t25 with a decent amount of supporting mods it worked ok and had an acceptable pressure drop but after a lot of hard driving you could stop and feel the core... where the inlets were on the endtanks was considerably hotter than the rest of the core... backing up the fluid analysis of the design.

I normally use PWR cores on all of my builds (s13 is getting one as well) since they are a high quality unit with a grest core design plus I get them considerably cheaper than what PWR retails them for which doesn't hurt
