Intercooler question
I`m still working my way around my new to me procharged 383 `90 coupe. As I stated in my last post here, I`m basicly in the dark ages when it comes to understanding FI. I was wondering what would happen if I took off the dual intercooler setup that is on the car, & ran a connection right from the supercharger to the throttlebody. It just seems to me that its a long route for the air to travel from the supercharger, down to the intercoolers(which are located on each side of the car down by the fog lights), & then back up to the TB. Is taking them off a good idea or bad & why? Also taking them off would give a little more space in front of the engine.
Thanks, I like to think that I am never too old to learn.

Well i think right now would be a good time to read up on f/i. get some books on the subject as this will help you understand the basics of f/i.
But to get to the question, you could easily run the tube from the supercharger to the throttle body. but then you will have to worry about excessive iat's from the hot air that the supercharger produces when it pressurizes air.
The long routing of the charge piping is not a big deal as the amount of air the supercharger is able to displace is massive relative to the volume of the piping.
I would leave them on unless your having issues with couplers blowing off or similar annoyance.

For each pound of boost you raise air temps approximately 10 degrees. Intercooling helps cool the charge but won't work very well if you are stuck in traffic then jump on the car when traffic clears.The intake charge is still hot because of lack of cooling air circulation. If you go the route of removing the intercooler then I would suggest a menthanol set-up for cooling.

kenv, your car has the dual intercoolers in front of the wheels correct? I was wondering if you have a stock airdam on the front of if you have the one that was put out with the procharger kit. I have been searching for weeks for a picture of those pieces but have had no luck at all. Could you post up a pic please????

The intercoolers that comes with the kit are relatively small, after a certain point they heat-sink and essentially end up being useless.
In theory, eliminating the intercoolers will allow for sharper throttle response (less overall volume to fill in the intake track). The methanol injection system seems to be a very compact, efficent method of intercooling.
I would prefer to go with larger dual intercoolers, or a larger more efficent single intercooler, or methanol injection.
Keep in mind, that by eliminating the intercoolers, you'll also drop some weight, and reduce the complexity of the system.
JMHO.
* also, the centrifugal supercharger is the most efficent supercharger on the market, and they don't produce nearly as much heat as positive displacement blowers (roots style).

I have read that they are a little small too, but this is my first project like this and it is going to be a daily driver so it won't see abuse like a dedicated race car. I am just concerned with getting air to the coolers and thought that the airdam pieces were modified to do that. I was also thinking of putting some puller fans on top of the coolers and possible a CO2 sprayer on them to cool them off quickly when sitting in traffic. I was also thinking about some hood vents but hate the idea of modifying the hood..
would there be any value in adding meth injection in conjunction with the intercoolers at a later time if i need more boost?

I wouldn't do the extra fans and CO2 only because you're adding more complexity to the package, more weight, and more items that can potentially go wrong/bad. Just my opinion.... it also sounds more like a bandade to the problem.
you can run the meth injection along with the two intercoolers, OR by itself without the intercoolers. Either way you should recognize some improvements in the intake track temperatures... In fact, depending on how much of a restriction the current intercoolers are, you might actually pick up a significant amount of power eliminating the intercoolers completely and going with just the meth injections.

Are you running an FMU or a tune and big injectors?
im running a p600b on my 93 lt1 hotcam / lt headers w/ tune and 60 lb/hr injectors.
I ditched my procharger intercooler recently and instantly saw an extra 4 psi ! at redline.
Its now making 12 psi at 6000 rpm which is more than I am comfortable with on a stock bottom end. I had to set my rev limiter to 5700 rpm (near stock) in hopes to keep the stock bottom end together.
Im spraying 50/50 water/meth also w/ a blowerworks gaseous intercooling setup.

definitely drop the intercooler. Its a po$.
