Oh and I forgot to say Thank you for at least trying on this. I still say it has a lot of potential, but potential probably isn't everything (ie. money). But again thanks.

At that time the ECUtune firmware changes were not the "aggressive" versions we use now. AKA they required the ECU to use the knock sensors to learn in a large amount of advance on top of the primary ignition table. A couple cars did this well--many did not.

We were originally going to have the fabrication work done by someone else but somehow I ended up doing it myself and the machine work was done on a small, cheap, chineese, manual mill and lathe. The manifolds and pulleys were really beyond the capacity of the machines and as a result are a bit rough. With access to a nice big CNC mill it actually wouldn't be a big deal to clean the machine work up and true up the mating surfaces if I came accross one of the ones I made back then but I would definitely do so.

So long story short just the originals were made and they could use some refinement.

Dang... I swear I have seen supercharged SVXi out there. Are they from a different source? One-off creations? I want a bit more power in my SVX, the 5 speed is amazing, but a little more zip would sure be nice. Anyone selling one of these old kits by chance? :-)

Time to learn how to fabricate. I have one of the kits and I have had to rework most of it to get it setup well. Looking back on it, a large single turbo on my built motor would have gotten me a lot more for the money with way fewer headaches.

Can you expand on this thought please?

I'm limited to around 11psi while over revving the supercharger before redline. On a high compression motor this may be fine, but I have a forged lower compression motor. I could get much more out of it with a more efficient turbo pushing higher boost levels. To get any more from my current setup I would need to either add a turbo, or go to a larger supercharger with a larger pulley so I don't over rev it.

I'm a few months late to the show here. I had the first customer car with the kit. I was military at the time. It was originally a 1994 Red FWD L model. The trans went out during tuning the car. I had Tom drop in a 6-speed manual. It was running 9lbs boost. I transferred out to San Diego and sold the car to someone from northern California, along with parts to start a built engine (CP pistons and Eagle Rods). I want to say I sold it some time in late 2010 or early 2011. I couldn't get it tagged and had moved on into a new Camaro SS.
