230 whp Supercharged Vert Complete! Dyno and In-Car Video and SC Comparisons
My supercharged Vert is finally complete. It made 230 whp on the dyno which is a 65 whp increase with only 6 psi. Here is a comparison of several different supercharged FC dyno charts that I have plotted on top of each other.
Here is a video I made with some crappy nighttime footage (to get the sound experience) and the dyno pull (done in 3rd gear):
Right Click, Save As...
I am the third owner of this supercharger kit. The original owner was Travis Shrey who has (had?) a sweet red Vert that I used to have on my desktop. It's strange that I ended up with his exact supercharger kit.
These Paxton superchargers are still used by some of the Mustang guys. A relatively cheap (<$1k) rebuild/upgrade exists that allows the supercharger to flow 1400 cfm (up from 800 cfm in a freshly rebuilt SC like mine); however, it does make the unit a little bit deeper, so I'm not sure if it will fit without doing some notching of both the supercharger and the intake manifold. Because this project ended up costing me a bit more than I expected, I'll probably jump in for another $1k or so and try to break 300 whp with some type of supercharger upgrade.
Mods to the FC:
Rebuilt S5 Motor with very mild streetport
Port-matched/polished manifolds
Full Racing Beat Exhaust (no header, exhaust manifold then full RB)
K&N Filter with heatshielding
S-AFC II
550 cc secondaries
FD fuel pump
Aeromotive FPR
Cooling Mist water injection (still tweaking)
ACT Clutch (not sure which one)
Racing Beat Lightweight Steel Flywheel
Nelson/Paxton SN89 Centrifugal Supercharger @ 6 psi (max until rebuild/upgrade)
Greddy Type RS BOV

I love you man. You've done something that I've been wanting to do. And 230hp is damn good enough for me. You must give me more on the setup, price, etc....

I would just like to say that I realize that this was not the most cost-effective way to get to 230 whp. The kit was not exactly a "bolt-on" installation and required modifying the secondary fuel rail and numerous other fitment-related issues. The alternator pulley was also wobbling which required some machining. I did not install this myself, so I had to also pay for labor.
I bought the used supercharger kit with a nearly-new ACT clutch for $1500.
I have a feeling the car is still running quite rich, but the dyno did not log my AFRs for some reason (realized after the fact).
I'll just say that my total investment in the FC is over $12k.

Very nice setup.
I know that vert's got to be a blast to sport around in.
You didn't show the daily driving fun part - the torque from 2K to 4K.
That' where the SC shines before turbo's really get going.
My setup is kind of in between a SC & a big turbo.
It's a turbo from a J-spec automatic.
Its smaller compressor spools sooner, but without the top end of the stock turbo.

SonicRat, do you have a dyno chart available? I'd like to put it on my FC supercharger comparison chart.

I was just reading another S/C thread, I believe SonicRat got 270 rwhp out of an M90 (t-bird) air-water cooled, and more than plenty of other money spent. he said past 270 it just blew heat.

We did not pull any timing from the CAS, and there are no signs of detonation.

Superchargers are always going to be more expensive than turbos considering the TII is factory made and oh so cheap to modify if you follow instructions.
FWIW I'll have less than a grand dumped into my own twin screw millenia S supercharger project (FMIC, Megasquirt, TII tranny) when all is said and done, and a bit of self done fabbing.
Supercharging is harder than modding a TII. But that's not the point, nor is its relative frugality or lack therof.
