Hello all,Here are some build pictures from this years 2009 USF Formula SAE car. The car has been completely designed, built, and raced by University of South Florida Engineering students. The car is currently running a Garrett 20 mm turbocharger to complement the 20mm restrictor rules, employs a Suzuki LT 450R single cylinder engine (70 hp dyno tuned, weighs 450 lbs), pulls 1.8 g's in the corners.All frame tubes and most tabs are 4130 chomoly welded by me and one other member. All aluminum was welded by myself. ER-70S2 filler on a Miller 300 DX. All aluminum is 6061 and used 4043 filler. I still have to work on filling in my tack welds, evident on the gas tank in the following pictures. Most machine work done in house on manual lathe and mill, but CNC was sent out to a local machine shop Sun Hydraulics.All pictures are in no particular order, just how photobucket arranged them. If you have any questions, feel free to ask...Last edited by BLUE2KSS; 04-27-2009 at 06:58 AM.Mechanical Engineer

ooks like a good time. Im at Wentworth Institute of Technology in boston, and were doing the Formula SAE hybrid next year. I sure wish that word Hybrid wasnt in there! This year were designing the electrical system, which turned out to be a pita.
Reply:i know what you meanno thanks on the hybrid either, we have a hard enough time getting the regular fuel engine to breathe through the restrictor and run on 100 octaneMechanical Engineer
Reply:What are the engine guidelines for the SAE competition??Rex
Reply:Must be under 600 cc's, and breathe through a 20 mm restrictor. must run on either: E85, 100 octane, or 93.other than that, any forced induction is allowed, as is any engine combo as long as you are within the above guidelines.Mechanical Engineer

Reply:I worked a very tiny bit on the FSAE car at GA Tech back in 1991/1992, and then got much more involved with the car at Southern Tech (now Southern Polytechnic State U) in 1994. All of this was prior to working as an engineer for a sportscar manufacturer for over 12 years following. Great way to get onto the auto industry and be seen!Anyway, I still attend one local SAE meeting each year - the spring one that alternates between GA Tech and Southern Polytech where they and Auburn introduce thier newest cars about one month before heading to the competition in Detroit. It was actually just a few weeks ago. The thing I had to laugh about when looking through your pics was the giant billet uprights. It seems each year one of the teams decides it's a huge weight savings to go from fabricated to billet and another thinks they made a huge weight savings going the opposite way. Anyway - not saying yours don't look great - just seeing yours made me think of the cyclic trend!
Reply:I really envy you guys at the bigger schools. I went up to UT Arlington recently with some other guys for our district ASME conference and they had some of their FSAE cars on display. They brought out their '03, '07, and '08 cars and let us look at them while they ran one at a time around a course they had set up in a large parking lot. Pretty cool stuff. Makes me wish I could have participated in it or even BSAE. Good luck at the comp!MikeConstans Fides et IntegritasLincoln Weldanpower 150 ACAirco Aircomatic MIGet CAV II w/ spoolgunMillermatic 30a wirefeeder
