What are the main differances? I know the end tanks will be but what else? Do the precisions fit without any cutting?

I will be on Full Blowns dual pump set up with ID1000s on e85. Full-Race manifold with a 6262. I will max the fuel out and see what kind of power I make. I just do not know if the inline 600hp is enough for my needs.

Ya said they are rated at flywheel horsepower numbers, so it makes me doubt that it will support me as I hope to crack 600whp. I do not understand how they rate the intercooler cores by horsepower though. Doesnt a lot of it have to do with how efficient the set up is? A more efficient set up will push cooler air so maybe a smaller intercooler would be sufficient. Comparing to a samller turbo running a lot more boost to achieve similer power numbers. I think it will take right around 20psi to get there.

I need opinions! Will I need a bigger intercooler?

i think it has to do with how much cfm it can flow before it becomes a restriction.

my opinoon, you will need one that can handle 600-700whp. so like 700-800 crank.

 

The Precision and Inline Intercooler are good for 600 whp and that is exactly were they max out both have been tested.

 

Rob! just git 772 whp and he has the 600 hp intercooler i think. He said he has to upgrade soon to the 750 hp one tho. Maybe he'll chime in here or you can pm him

 

i would go with precisions 750hp front mount man. you should be satisfied with that piece, not to mention it is a VERY high quality product. i just sold my precision 600 for a bigger one as well

 

Inline's core is from Precision and as you said the ends are different than the off the shelf unit, so I have been told.

As far as the rating goes, it is more or a guide than anything else. There are several variables at play here which figure into the total heat transfer.


(1) Turbo Efficacy - IE how much heat is it generating

(2) CFM & Distribution Inside the Core - As the CFM Increases the Pressure Drop Across it does also. So if your turbo is outputting 30PSI and the case at that CFM causes a loss of 6PSI your engine will only see 24PSI but you have a large amount of heat generated b the heat of compression to dissipate.

(3) CFM & Distribution Outside the Core - How easy is it for air to get through the outside of the core and how well is it distributed when it goes through.

With the power you are looking for the larger core would be a could stepping off point however the smaller should do the job if your turbo is efficient in the pressure range and CFM you will be running. Even if you don't end up making as much as you originally estimated the larger core will only help.

Someone like me using a relatively small turbo to try and maintain a lower RPM spool and looking for numbers like yours would have been better using the larger core, however you can offset the use of a larger core by installing an intercooler sprayer, Meth Injection or nitrous at higher flow rates.

 

Yeah I am thinking the precision 750hp too. Why does precision call it a 750hp and inline calls it a 800hp. Same sizes just different end tanks. The inlines ones are made to fit without cutting the car but they are more expensive.

Anyone have installed pictures of the 750hp or the inline 800hp? I wonder what it takes to get the precision to fit.

THE THING IS THAT I DO NOT EVEN KNOW IF THE ID1000s WILL HIT 600WHP ON E85!! It sucks there is just no definite answear, I am going to go crazy running different options and scenarios. I really do not want to waste money on things that are not necessary.

 

as someone said earlier. I made 772whp on mine. We werent doing pulls right after another. I noticed the intercooler wasnt super cold when i switched over to race gas making around 700whp. Before then it seemed to have been fine. I made a pull on 758whp and then 3 minutes later 772whp. I cant give you any real technical data But like i said above 700whp it wasnt staying real cold. Ive been running around at 590whp on the street with the inline 600hp one with zero problems though. I will continue to use it until mine sells. I have no posted it for sale since you said you were interested but let me know so i know if i should post it up or not.

have you considered going with a vertical core by threadstone or spearco? you might need to custom fit things, but because of the efficient fin design and minimal psi drop it might be an option..
