Also, I just saw a thread on here where another guy (who did PM me BTW so no one bash him anymore), asked about supercharging his IDI. I will post this here since it is my thread. I would do this again ESPICALLY with the knowledge I have learned by myself. BUT, remember, I am using the light duty stuff with a 9" and a slip yolk ds. If you were going to do this to make stupid power, you would need two things. At least a 3/4 ton setup, and probably some ear plugs. Remember, I am only running low boost for my own reasons.
So, for this, the first thing you would want to consider is how to relocate your alternator (serp setup) so you can use a belt for that. Second, I would move the pulley in front of the belt routing. This will ensure that you can adjust the pulley size you want to run by adding size to your crank pulley, or adding a jack shaft pulley to the mix. I am already committed to what I have mostly so I am going to use the single belt and custom pulley on the SC. Below 8 psi, the eaton is very efficient. After that, the air starts to get super heated. So, with 8< psi, no need for an IC.
I recomend not going with the SC unless you are not going to DD your ride. Mine will be capable of DD duties, but I am going to use a lot of insulation to keep it quiet. Not that I do not like the wine, but I want this thing to be as quiet as my t-bird...which is pretty dang quiet.
You are not going to save any money going with the SC and turbo kits are readilly available. Like I said, I would do it again, but I am hard headed and had more than 90% of the stuff I needed to make this work. I only needed a pulley, a piece of plate, and a longer belt. The rest was just spare parts I had lying around.
Though some say my results are less than spectacular, they are almost 100% what I was trying to achieve. Even those who claim there is no boost lag on their turbos, I have boost when I am driving without even having my foot on the go pedal. Now THAT is having no boost lag, and that is exactly what I was trying to get. Watch the video posted on page 11. At 55-60, even coasting (manual tranny now), I have 5-6 psi.
After all my bugs get worked out, it will be really close to what I want. I will probably have my spare case ported and increase the size of the inlet to make it even more efficient. If I wanted more power, I could turn up the fuel, but land speed records is not my goal here.
