  1. Blew up my Boss motor on a track day - Why???

    I have a 2014 Boss 302S race car that I bought new in September 2014. It's never been raced, just used for NASA TT and Shelby Club events. During about its 4th or 5th event, in July 2015, it blew its engine just like yours did. My car was new enough and I provided video like you have and data...
  2. GT350 versus Boss 302S

    Answering questions from the above two replies.RA was the first high speed event for the 350. Ran NASA TT at NCM in March, but that was on street tires in cold and wet weather. Have about 10 events on the 302S, mostly NASA.The 302S wheels are the Ford Performance 19 inch wheels. Same as...
  3. GT350 versus Boss 302S

    We both think the 302S is easier to push to the limit, at least at road America, which is a combination of high speed sections with tight turns at the end of those sections. The reason is the ABS action in the 350. If you hit the brakes a little too hard braking late at the end of the high...
  4. GT350 versus Boss 302S

    My son and I took my 2016 GT350 Track Pack and my 2014 Boss 302S to the Northwoods Shelby event at Road America a week ago. On the way up, we were wondering which car would be fastest. I thought it would be a close call, and that turned out to be true. We switched back and forth between the...
  5. GT350 dyno results - 98 octane versus 91 octane gas

    I went with the Cooltech bar, because they offset the harness bar back about 6". I like to slide the seat way back to get in and out of the car. The Cooltech bar allows re-installing the back seat. Not the lightest setup, but I wasn't worried about a few extra pounds.
  6. GT350 dyno results - 98 octane versus 91 octane gas

    I turned in the 98 octane graphs, because this car is so heavy that this power level doesn't get close to the TT2 limit. I set my minimum weight with driver at 3700 lb, which is 200 lb lighter than I think it can ever get down to. That's to make sure scales error doesn't show me under weight...
  7. GT350 dyno results - 98 octane versus 91 octane gas

    I was anxious to get out and try it, but we wouldn't have driven 11+ hours at this time of year in the Midwest if there weren't some other attractions, like the Corvette Museum and touring the Corvette plant. Never had a Corvette, but still find anything related to performance cars interesting...
  8. GT350 dyno results - 98 octane versus 91 octane gas

    Ran the GT350 in a NASA event at the National Corvette Museum track. The track had two gas pumps. One with 3 choices of VP race gas and one with 3 choices of Mobil street gas, with 93 octane being the highest. I noticed that a Shell station near the track had 93 octane, so it must be commonly...
  9. GT350 dyno results - 98 octane versus 91 octane gas

    Would be interesting to do that, but not in the near future. Its in my home garage right now to get it prepared for track events. Maybe we will run it again when it's been to some track events. It only had 310 miles on it when dynoed. Most from driving it home from an out of state dealer.
  10. GT350 dyno results - 98 octane versus 91 octane gas

    Here are the dyno graphs. The first 3 runs are pump gas and the last 3 are race gas (Sunoco 260GTX)
  11. GT350 dyno results - 98 octane versus 91 octane gas

    I'd be glad to if I can figure out how to do it. The image that I have of the paper printout is a .pdf file (Adobe Acrobat), and photobucket won't accept that file type. Can someone tell me how to get it into an image file type, or another way to get there? I did look at the thread on posting...
  12. 2016 Ford Performance Parts Catalog

    I installed Ford Performance's oil separator on the passenger side of my GT350's engine, but seems like I saw somewhere that they recommend one on each side of the engine for track use. Why do they only offer one?Or is a driver's side one not really needed. The left and right valve cover...
  13. GT350 dyno results - 98 octane versus 91 octane gas

    Dynoed my new GT350 on the Dynojet at my son's restoration shop last Saturday. With pump gas that is supposed to be 91 octane, we got 429-434 wheel Hp (about 510 engine Hp at 85% driveline efficiency) in 3 runs with pump gas. We were down to less than 1/8 tank of gas, so we filled it with...
  14. WTS 2013 Laguna Seca with 123 miles

    VIN 1ZVBP8CU9D5279519 I bought this car on 1/26/13 with the intent of using it as a track car for one of my sons, but he developed an inner ear problem which makes him carsick during aggressive driving, so we never used the car, as I already have a 2012 Laguna that I use, and my other son...
  15. WTB 2013 SBY Boss 302

    I have a 2013 SBY Laguna Seca that is "showroom new". It has only 123 miles, which are the miles driving it home from the dealer 18 months ago. I bought it for one of my sons to move up from a Mach 1 to a Boss as a track car (I use a 2012 Silver Laguna Seca for track days), but he developed a...
