I'd be interested in more details for the kit. Looking to supercharge or turbo late next year, so doing my research and planning out end goals currently. Additional details would be nice :-).

Here you go. First page sums it up pretty much but the rest of the thread proves it out with many satisfied customers.

OK... looks like you didn't read the first article so here is a quote from a second. "Comparing air and water, air has vastly lower heat capacity per gram and per volume (4000) and less than a tenth the conductivity, but also much lower viscosity (about 200 times lower: 17.4 × 10−6 Pa·s for air vs 8.94 × 10−4 Pa·s for water). Continuing the calculation from two paragraphs above, air cooling needs ten times of the surface area, therefore the fins, and air needs 2000 times the flow velocity..."

The point is that water is much more effective than air for cooling. Additionally, for a short run / race you can use ice or chemicals to drastically drop coolant temperature to well below ambient air temp.
As I said before, this debate is ongoing. More power can be generated (as you have demonstrated) with significant mods (upgraded fuel system, pulleys, impellers, cog belts), but if you were to compare apples to apples... Stillen kit parts and only change W2A to A2A, that would be something that would get my attention. BTW... how is your driveline holding up? I broke an axle last year with 443HP/323TQ. At a certain point you reach the limits of the car. If you heavily modify the car it becomes less reliable and you might as well bite the bullet and get a GT-R.

Not to start an argument, but you can't just compare specific heat capacities of two different media being used in 2 different applications and compare them. There are so many variables that change between the two systems that you would have to have a very complex analysis to determine the difference between the two. It is true that if you replace the water in the Stillen cooler with air that it would perform worse. The problem with your comparison comes because not only does an intercooler have MUCH more surface to work with, the velocity of air is faster in a front mounted intercooler, and the temperature difference between intake air and ambient is greater, all leading to better heat extraction. This is not even to mention that the vehicle has no clue what the intake temp is, to be most reliable you would have to put a probe into the lower plenum after the Stillen cooler to get a good temperature reading.

That is the first axle I have heard of breaking and the boys over on 370z are making over 600whp 500wtq daily and most are throwing on DRs and running it down the strip. To break one of these with 340tq and street tires points in the direction of a complete anommaly.

In regards to the Adam Sandler like "Water is betta" argument. Yes, in the perfect application it can be. In this application it is,well,far from it. Think of all the air blowing out of your exhaust at 7500rpms. Now, ALL of that air has to come into the motor also and all that air has to pass through.... THIS....Laughable at best. Yes you can have a proper water setup to cool 10+ psi very well...but guys, this aint it. It is the reason we have seen motors let go at anything more than the 8psi pulley. It just comes in WAY to hot. I dont care how big of a front mount you put on this thing. Once it heat soaks its game over.

Can someone send me a link to get that exchanger? My kit will be shipped April 15th and want to get it all done from the start, thanks
