I have the Protomotive 5 inchers and my IAT's don't go above 114 after 45 minutes of hard driving in Houston heat/humidity.

 

Is there really even enough data out there regarding IC cooling performance and flow to be able to say one is better than the other? There are no back to back dyno runs or IAT performance on the same car in the same conditions.

To say one is better than the other is just a guess and because one vendor has a 1300hp car doesn't mean the IC's are efficient. Maybe that same car could do 1400hp with better IC's... Who knows?

 

Chad have you spoke with Todd K. about his intercoolers?

 

Nope - I was just using that as an example where nobody knows anything and an IC could be choking a car. But unless someone comes up with a car and starts swapping IC's and comparing results. It is all moot IMO.

I think Earl started some good debate and information on GT2 IC's, but still not enough data to determine what other IC's performance are in comparison. We need a vendor to step up and prove their IC's perform better than the competition. Right now all we have are a few bench flow test and some IAT charts from a totally different car and environment.

That just leaves us with stabbing in the dark to get the best for our cars.

 

Maybe it could be an opportunity to design your own IC from scratch, just like you did with the inlet manifold....

 

my post was towards CJV as his name is Chad but thanks for the reply Rainey.

the 997.2 intercoolers are good for their power level but when you almost quadruple the flow and horsepower levels they were designed for i doubt they would perform upto the task.

so far id say Protomotive has the most experience tuning and modifying 1000whp cars he has found a setup that keeps temps in check during the southern heat on a GT 35 equipped car.

 

lol, I am Chad as well!

 

Chad, you probably know more about ICs then most of us.. so I really don't understand the point... we can debate bell cores, secans, garrett, etc etc... But I am one who is pushing 1000+ rwhp and have tried a few different core sizes... bottom line is you will not really know Chad until you actually do it one your one off car... thats what Im doing... I know the 4.5s held up... now Im on the 6".... will they work better? we will see any day... until then I can speculate till Im blue in my face.... and seeing how you keep switching parts on your car I have a feeling you will probably go thru a few sets before you settle...
good luck

www.mezzotech.com, they're stuff looks interesting. Again aerospace focused, very difficult to get their attention.

 

Hi,The last thing I replaced on my package of mods at my level were the intercoolers. It did feel like it pulled harder and quicker ,mostly in the mid range area.I used the AWE intercoolers which have bigger diameter hose openings over my X50/GT2 ones.Which I have for sale with black Vivid silcone hoses for a cheap price.

 

The motor is going onto the engine dyno one more time in about a month. We will actually be comparing some IC's. If anyone wants to provide theirs we can arrange to have them tested.

 

Not in any detail. These cores may be good, I don't know. I would not use the end tanks as I have a good idea what I am looking for there.

 

If I was able to settle on a specific core we could do this. We did in fact do this with the IC's we currently have. However this was before we more than doubled the hp. We need larger cores and tanks that equally distribute the compressed charge to all IC tubes.

 

Mark,

I do know a lot about IC's, however surely not everything. I have discovered I learn far more by listening than talking. I have already picked up one bit of information from this thread and hope to pick up some more.

I had a pretty trick set of IC's on my old motor. The cores were smaller then as were the inlets and outlets seizing. We also utilized liquid CO2 cooling of the cores and the double jacketed Y pipe. The interesting thing we discovered was after a certain ambient temperature the delta was minimal.

Would you like to have your IC's included in our test? Provide a set and I will have them tested on my dime when we test some others. If they are the best ones I would be happy to pay for them. Otherwise I would provide you with the results and return them.

 

My guess is the two aerospace companies, Secan and Marston should have a lot of R&D in their product. I intend to test at least one of these cores against a couple of the others.

If you look at crt developments (who use Marston) end tanks you will see end tanks designed to distribute charged very well. We used similar designs on our old IC's. I want to see their pricing versus what I know it costs to build our our tanks. Then again, tanks are not our problem .... finding the best cores is.
