http://www.seanhylandmotorsport.com/ Sean Hyland and the crew at SHM have just completed a prototype build for Vitesse Autosport of Denver. This 2005 GT dyno tested at 518 RWHP, that's over 600hp at the flywheel-on 94 octane pump fuel! The SHM built engine includes a 1999 Cobra aluminum block for durability, forged steel crankshaft, forged steel crankshaft, forged steel connecting rods, forged aluminum pistons, ARP main and head studs, ported cylinder heads. The ATI D1SC supercharger with a custom SHM intercooler, is only putting out 12 psi boost to achieve this impressive power output. SHM replaced the stock 5 speed transmission with a Tremec TKO 600 transmission, knowing full well, that there was no chance the stock transmission would survive long behind 600 hp. SHM have developed a remote gear change mechanism to locate the shifter in the correct position in the 2005 mustang, and we have adapted a hydraulic throwout bearing assembly to the TKO 600, to be compatible with the hydraulic clutch which comes stock in 2005 Mustang. We also designed and built a new transmission crossmember and mount, and a new driveshaft assembly in order to complete the installation. The result looks like it came from factory, and the shift quality is great. Backing up the transmission is an aluminum flywheel, HD pressure plate and HD 26 spline clutch disc. The rest of the Vitesse Mustang features Brembo 14 inch front brakes with 4 pot calipers, 18x9.5 SSR Wheels, 275/35/18 Toyo RA1 tires, SHM sport springs, HD front and rear anti roll bar, Steeda adjustable panhard bar and billet lower control arms, strut brace, bump steer kit, raised ball joints, JBA long tube headers and H pipe, Magnaflow mufflers, SHM aluminum 3 core radiator, custom hood, front splitter and rear spoiler. The car is also outfitted with a HD limited slip differential, and 4.10 ratio ring and pinion. Beginning June 10th, Vitesse will be testing the car on the Players Run, a race between Seattle and Las Vegas, running times segments at many race tracks on the west coast.
