I am kind of curious as to why a slim fan is needed if the fan is between the radiator and intercooler

 

I was under the impression that the 3052 was a 3076 turbo with the FP exhaust housing on it instead of the garrett housing. And the 3065 was a GT30R with a GT35R compressor wheel on it instead of the 3076/52lb compressor and also a FP exhaust housing. Someone let me know if im wrong.

 

Another thing, i was just reading this thread and started researching some of the kits that people listed mainly the Shearer, AMS, Buschur, and Full-Race. One of the reasons the Full-Race kit is so much more expensive is the fact that it includes a large intercooler with it, it is 24x11x3, and by comparison AMS's race intercooler is 22x12.4x4, and buschurs is 24x13x4, so that sorta offsets the cost of buying a new one. AMS wants almost $1700 for the race intercooler with piping, Buschurs is $700 without, and Full-Race comes with the piping. Now i don't know the flow rates vs. pressure drop with all of these but the sizes seem comparable, also i wonder what intake manifold alot of these cars are using, i know AMS and Buschur make their own but are they using their intake manifold when making this amount of power and track times?

 

FR - 24 X 11 X 3 = 792 cu. in.

AMS - 22 X 12.4 X 4 = 1091 cu. in.

Bus - 24 X 13 X 4 = 1248 cu. in.


So which did you say was larger?

 

I'm leaning toward the Buschur Kit, Performance plus cost is very impressive.

 

Id love for FP to chime in. The FP3052 just seems a little more streetable for the 2.0 guys. Faster spool but still some huge power potential, especially with alcohol.

 

Your right

 

Whoops Ted B my bad i didn't take the time to calculate the acual cu. in. of the intercoolers sorry about that. But good info none the less i'll have to remember that when i build mine, looks like the bushur is the way to go.

 

bigger isnt necessarily better

 

True, size is but one of several factors that must be considered when evaluating an IC.

My point is simply that the physical capacity of an IC is calculated in 3 dimensions, not 2.

 

there are 2 fans on the radiator...one on the engine side, one on the bumper side.

 

one thing to think about (which is never accurately mentioned by anyone except C&R) is that if you are going 200 mph, and have a 4" thick intercooler, the air enters at 200 mph, but leaves the back of the IC (and heads towards your radiator) much warmer, and at only ~10 mph

the ideal way to size an intercooler is to calculate the required mass flow rate before the core sees a real pressure drop, and use that to set how much power the car is going to make. (ted b, im sure you already knew that)

 

bingo

 

I usually agree with Full Race, on this intercooler stuff though the theories that get thrown around I could care less about. Too much time building, testing and measuring. There isn't a way to physically put a big enough intercooler in an EVO without cutting the hell out of it, if you plan to stick with a thin 3" core.

In this case thicker is better.

The EVO also has an excpetional cooling system even stock and overheating I have yet to see in any conditions.

What change did you offere to the 35R to make a better spool?
