Ray's 350Z
(Update 07-22-2008) New Dyno Numbers 
If Ray's 350-Z was a beast before with 600whp, it is a absolute monster of a street car now. Recently the car laid down over 860 horsepower to the wheels. This is an unbelieveable car which is scary fast on the street or track. The fact that it laid down over 860 horsepower is not a huge feat until you take into consideration how simple and clean the car appears, also the fact that this car is driven alot. The car was built and tuned by Ray Wilson here at PF Supercars with the following parts:
Standard Greddy twin-turbo system
Haltech Platinum engine management
Pauter rods, Arias Pistons
ARP Fasteners
PFS fuel system. fuel return
PFS 4" single exit exhaust system
Spec twin-disc clutch
Ernie's RX-7
As most of you in the rotary community know, this car has transformed from a mild single turbo setup to a 735 whp beast. With many different engine combo's from street porting to full bridge dowel pinned clearanced motor, it has seen many hours of dyno time. With the PPG dogbox tranny upgrade, it was made even faster. Now, plans are to dial it in and see what et's it can pull off. This winter will possibly bring a totally new transformation of this 2 rotor powerhouse. Be on the lookout!

Phil has done a lot of interior and electronic upgrades as well, but the mods listed are the main ones.The car made 740 whp with the nitrous through the automatic.

Greg Smith - RX-7
Car has some history behind it. Once was Ray wilsons Street drag car, that went 9.80 and was trapping 145mph back in 2001-2002. Since then, it had changed hands and a different build was uptaken.
The car was a fun street car, and was very reliable at the high hp it was run at. It made 500 whp at 20 lbs boost on 110 octane and 610 whp at 28 lbs boost. For a regular street port on a 66mm compressor, the power output was really impressive. It had a nice powerband from 4500 rpms to 8500 rpms and response was quick for being a non ball bearing turbo. The car was sold and is currently under a new build at PFS.
