I purchased a greddy 2 row 2.5" thick fmic for 20b conversion I'm working through. I didnt realize how small this was compared to the blitz fmic I used to run.

Do you guys think its sufficient for 18-20psi on an 80mm turbo so long as I'm spraying 1000cc water/meth beyond 10psi and above?

 

Picture of the setup in need of intercooling

 

Seems small, but the proof is in your AITs, if you can get away with sub 200F then you're fine.

Off hand, it seems like the AI should easily keep temps down for 18-20psi range. I'm just hesistant to chop up this I/C when I could exchange it for a larger setup. However, smaller is better if AI will keep IAT in check.

 

I have an old school Greddy 3 Row FMIC. Its 4" thick.

It mounts like the Blitz with no cutting of the front bumper and the piping run is super short.

Buy mine for $450 and sleep well at night.

intercoolers are a wonderful necessary evil and while they all look similar they do not function similarly. many intercoolers act as restrictor plates as to flow. and this is on a 2 rotor. there is a big difference between the flow of good and not so good cores.

last winter Beyond Redline hooked up a 4 cylinder engine to a big air compressor (you need to flow around 1000 CFM) and tested cores, end tanks etc...

their conclusions were proved out on one of my customer's engines which ended up being flow challenged above 575. a better IC will not only raise the power above 600 but significantly lower IAT.

your 3 rotor will be flowing 50% more air making a proper intercooler important. a great intercooler always pays dividends as to cooler IAT... even when not in boost.

my SM Pettit Cool-Charge 3 takes 130 degrees out of the air from the compressor. W/M AI removes another 30.

your car looks like it will fly.

What would you recommend as a proper flowing intercooler?

I was under the impression that a thinner quality intercooler such as a genuine Greddy 2-row would have little pressure drop and flow quite well although it may not remove as much heat as a thicker cooler. I'm trying to find a balance between what will yield this best efficiency in combination with the AI and also not so large as to block all the airflow to the radiator.

I've been seeking out a genuine greddy 2-row which should be 3" thick and return this knock-off 2.5" junk cooler. If this is not adequate, perhaphs I should go 4" and purchase a core / weld on end tanks? I've been spoiled by the previous Blitz FMIC setup and overlooked the necessity of this step.

Thanks again Howard for the help.

 

as an example, by simply replacing a bad/aftermarket intercooler on a Hyundai Genesis coupe w their purpose built IC, Beyond Redline moved the power from 270 to 320.

my bet is there are as many IC limited FDs as there are single turbo FDs w leaking turbo manifold flanges, and that is a big number IMHO.

i do think ICs are under-appreciated for what they can do to help our 4 to 8 hp per cubic inch motors get cooled. additionally, there really is a lack of data offered by many sellers as to overall efficacy/pressure drop and heat rejection.

turbo manufacturers (other than Precision) provide compressor maps but little is available as to IC data.

too bad, as it is very important.

Whats the CFM rating of your turbo vs the greddy 2-core?

 

I don't know the CFM rating on either and cannot find the CFM rating on the 2 nor 3 row. I do know that the turbo will move 120lbs/min. However, I will not need to flow that much as that would be nearly 900hp.

 

Well, the decision has been made. Thanks for the help.
