Love the crinkle red too, good old APS fmic kits.

Booo, we don't need basic in car driving, we want to see tire carnage!!!

If there is sufficient interest in a red manifold we could do a limited production run of them without a problem. We can do any combination that you want really. We just need sufficient interest. So if there were 20 guys who wanted the red manifold, no problem. 20 guys who want a black charge pipe...no problem. red manifold with black charge pipe? No problem...We just have to have sufficient interest to bring down the lot charge. The more parts we can send to the coater's the less expensive it is for everyone.

Thanks guys and its a great looking kit, do you hear the SC wind up?

I saw the answer earlier to the first question regarding adiabatic efficiency. Long answer short, yes, the supercharger is in its efficiency range and has plenty of room to expand.

I don't know what the weight of everything is. We haven't really been weighing the parts that come off along with the parts that go on. Keep in mind there are quite a few parts coming off the car. I will try to get this information in the next few weeks for you.

Last question was answered in the reply above.


Thanks for the info. I guess Im looking for temps above ambient at idle, hard driving etc.
Good to see the SC is in its ifficiency range too, thanks.

It's impossible to answer that question with a solid number or a percentage for any intercooler setup, air to air or air to water, because there are so many different variables. What RPM? What is the ambient temperature? How much boost? and more...

At idle, there isn't much if any difference in air temperature because you're not compressing the air. During the supercharging process the heat is created by the compression of the air molecules. If you're not boosting, you're not compressing the air molecules, so the air temperature will remain close to if not the same as ambient. I know that we were data logging this during our testing and I saw a graph that perfectly explains what I'm trying to say. I do not want to bother our engineer's this week as they are finalizing the instructions and CARB papers and I dont want to distract them but when things slow down a little I will see if I can get that graph.

Keep in mind that water is four times more efficient at cooling than air. Water dissipates heat 4 times faster than air and an air to water intercooler is actively circulating the coolant through its own system to constantly cool the air temperature. An air to air intercooler relies on the vehicle moving in order to cool. An air to water intercooler works exactly like your engine's cooling system. It doesn't matter if the car is moving or not, it's still going to circulate that coolant, the coolant will continue to pull heat out of the air and the front mount heat exchanger will continue to work like a radiator and dissipate that heat back out and cool the water that returns back to the intercooler inside the manifold.

Air to water intercoolers have been around for quite awhile. Here is a short list of some vehicle's made by the major OE's that use air to water intercooling systems:

Ford:
GT supercare
GT500 Mustang
Lightning

Chevy:
Corvette ZR-1

Toyota:
Tundra TRD supercharger

Here is a little write-up on air to water intercooling from Vortech:

Eh, my pipes are going to be wrapped in gold foil anyway so I dont care what color they are ;)

But you choose "gold" foil and not "silver". lol

Red Manifold, everyone loves how the nismo engine covers looks, lol come on that thing will look good with any car.

I wish my valve covers were Ford Engine Blue. :)

I agree!!! That Ford GT valve cover looks AWESOME!!!

I don't think intercooler failure is something to be worried about. Nothing bad will happen.

Yeah, after Stillen's response I'm not much concerned about it anymore.

I think as long as that water pump keeps the flow going through the intercooler, heat soak shouldnt be much of an issue and would be more of an issue with a front mounted intercooler at a stand still.

Heatsoak really wasn't what I was concerned about. I was just wondering how it's going to hold up to extreme cold.

Also,

I have seen a few people mention relocating their intercooler tank. Feel free to relocate that tank but keep in mind that you will need to keep whatever reservoir you use as the highest point of the cooling system. The bottle needs to be the highest point in the intercooler system because that is how the cooling system bleeds. If you have that bottle below the manifold/intercooler you run the risk of getting an air pocket trapped in your cooling system somewhere.

Just a little heads up/FYI.

A big hand for Kyle and all the folks at Stillen, for taking the time to deal with us, listen to our ideas, our bitching :tup:, our likes, dislikes, etc ad nauseam.

Looking forward to feedback as the first wave of folks install these superchargers.
