Air to Water Intercooler?

[911st]

I believe an Air to Air IC is a best practices method on an air cooled car for the most part.

However, I have been thinking a W/A system might be a benefit to keep the IC's heat from preheating the motor's cooling air and to a lesser degree from heating the intake air.

On top of that I am looking at 90-94 C2's. Would be interesting to do a turbo conversion and keep the stock non tail look.

Car's use would be some street but needs to work for DE's on the track.


Thus, looking for an education on a W/A system and how it might fit into a C2 turbo conversion.

Any help / thoughts?

Any place on a C2 to fit a radiator up front?

If you pulled the AC condenser out of the left front wheel well, you should be able to put an adequate sized radiator for your needs in the same location.

Thx Steve,

Want to keep the AC.

Your thought dose beg the question of how big the radiator might need to be for a 400whp Air / Watter IC?

I don't have any photo's, but most of the radiators that I have seen for stand-alone IC applications have been relatively small like a transmission or oil cooler.

According to the book Maximum Boost what's important in an W/A system is the volume of water in the system. The author says since you are generally never of the boost for more than 15 seconds at a stretch, you want enough water in the system so that the intercooler gets cooled water for that amount of time. So, if the pump is capable of pumping 8 gal per min, let's say, you'd want 2 gal in the system. I think the problem with W/A system is if you're on the track for an extended period of time the water in the system starts to warm up, of course, how fast this happens depends on the size of the radiator. It's a system that works very nicely for drag racing.

Keith,

For WA intercooling you need a high pressure pump, another IC or, or at least an IC, lots of additional plumbing, and most of all adequate space to make a decent install work correctly. Costs seem to be pretty significant and fabrication and installation are a nightmare.

WMI is half the cost and many times the benefits. Drastically reduces an engines propensity to detonate, drops head temps as much as 300*, cools air charge, boosts octain rating, piece of cake to install, weighs 15 lbs. plus water/Meth, and can increase HP as much as 20-30%.




Seems like a no brainer to me.
