home made supercharged legacy wagon

Re: home made supercharged legacy wagon
Y-pipe is installed. Drives alot nicer off boost due to the fact the motor doesnt have to pull air through 2 superchargers and 6-8' of pipe. In fact, the vac gauge reads ALOT closer to 0 now than it did before. And more torque and power off boost.
I need some more T-bolts and one 3" to 2.5" adapter before I can attempt full boost. So I have to wait till Wednesday......
I am going to be so pissed if I dont see any increase. While I know it might be futile to do what I am doing, 2 superchargers, I never ever ever ever saw any concrete evidence it wouldnt work.
But if it does, and even if it doesnt, I am now a pretty firm believer in the blow through maf for FMIC. Why? If you blow a charge pipe, you car still runs!!!!!! Its only if you blow off the two connectors that are either on the throttle body, or the MAF which would screw you. So now when I blow off a damn pipe (which I am sure I will, the motor will still run great NA until I can pull over.

The twins failed. In parrallel, they sucked ***. I would have to go to twin throttle bodies and it would work great, but..... thats work I dont have time or will power to deal with now.
Sequential, I saw a max 12 psi, but only in fifth gear over 4000 rpm. Pretty useless. Normally it was 10 psi, but the power increase didnt overcome the parasitic drag until 4500 rpm or so. And it drove like crap.
So I am back to a single blower, and will upgrade my pulley to 9", and modify the output on the current charger. Should have gone that way to start.
Bleah.......

Supercharger for sale, FOR DAMN SURE!!!
Yeah, its gonna cost to have a 9" diameter pulley made, to the tune of about $400. But it should be worth it. I was hoping the twin setup would push 14-18 psi, which would offset the parasitic drag, but obviously it doesnt. IF I was willing to put BIG (for me) money and time (even more than I already waste) into the twin throttle bodies, I am about 99% sure twin superchargers would work, because at that stage, it would be like a single supercharger ( x 2) on a 1.1 liter engine ( x 2).
but I don't have the time or money right now to be any more experimental.
So I will simply spend the money (easy enough to do) on the bigger crank pulley, and fab up myself the modified supercharger mount (this will allow a 100% freeflowing output) and I should get 12 psi.
Time will tell....

Re: home made supercharged legacy wagon
old wagon keeps getting faster. And still hasnt blown up. I admit to adding a little nitrous on top of boost, whats 100 shot among friends? My best previous was 14.5 at 92 mph at 8 psi boost.
60' 1.875
330' 5.721
1/8 8.829
mph 79.40
1000 11.523
1/4 13.797
Mph 99.00
73 degrees out and was my 8th run. The first 4 I was not running enough nitrous and too much fuel. The next three I had to dog it to win the bracket racing (lost the last one) so on the 8th run I went all out. Had the NO2 bottle been full, I would have easily seen 13.5 or better. The next runs kept getting slower and slower (13.8, 13.9....) as the bottle was pretty much empty.
