[QUOTE="01sportchic, post: 10935564, member: 64999"] Hey, guys! I know it's been a hot minute since I've posted. I believe I made a post a couple months ago on the turbo build, but if you don't remember, here are the basic specs on the car... [B][U]Specs:[/U] 1997 Cobra[/B] ~Stock 97 Cobra 4v B heads, stock upper and lower intake, stock cams. ~2003 Mustang GT shortblock, stock GT pistons, stock GT rods, stock GT crank. ~61mm Precision T4 turbo, custom turbo kit built by Power By The Hour. :rockon: ~38lb/hr Lucas Injectors, 255 in tank and 255 in line fuel pumps, -8 feed -6 return. ~Boost is straight off the wastegate spring, so average of 9.5-10.5psi throughout the run. ~Tuned by Ken Bjonnes :rockon: I've been itching to get the car converted to E85 since there has slowly been more and more stations carrying close by, so I figured I'd get as much documented as possible since I haven't really seen too may DD/stock motor conversions posted anywhere. We started the day off with getting a baseline pull with gas so there will be similar air temps and boost numbers between gas and E85. Outdoor air temp: 95*F Outdoor humidity: 42% [img]http://farm7.static.flickr.com/6144/6001219189_93a9e4085c_b.jpg[/img] We then swapped the injectors out for a set of High Impedance Siemens Deka 80lb/hr.
