i to switched from an mr2 turbo to a c5 a couple months ago, 2 different worlds, and the vettes are so much more fun in every way!
vipers are a lot of fun too, too bad i can't afford one, but i've drove many and you will definitly need heads/cam to compete with a viper around a road course, or anywhere for that matter, if he can halfway drive. good luck an would love to see the results posted someday!

take out the ls1 and replace it with an Ls7, he wont be able to tell the difference. if not that... nitrous and coilovers, i would have gone with T1 sway bars but you already got the hotchkiss. Try the PFDAT website for coilovers. any H&C package that you would do to be able to beat him would be noticeable... I run Nitto NT-01 tires, Im a big fan...

Nice video. As least in T-3, you stayed on the track. 
I always run the Panoz Track Days at RA. Since you had a GPS on the windshield & a hand-held camera, I am guessing it wasn't a Panoz event...neither of those would be allowed. So, when did you ru? Who sponsored it?

All I can say is good luck. If he can drive that Viper, you may be screwed. I'll be pulling for you - be sure to post up the results when you two run.

My father-in-law is quite the brave soul...
And that was actually a G-tech. I used it for measuring lateral G's (1.13 max that day)..
LOVE that track.. When are you going again??

Sorry I missed that...it looks like there were not too many cars, so you could run without much interference...very cool!
I agree...it's a great track! I am registered for March 4th. I am there for all the Panoz Track Days, so if you see my car, say hi.

Guys,
I keep hearing from Viper owners that the Viper is a handful even in a straight line. For some reason they like to end up wrapped around light poles more than C5s (yes, I know they don't have active handling).
Isn't the Viper driver going to have to be pretty good behind the wheel to take full advantage of the extra tq/hp he has over the Corvette?

Well I see you have the Z51 handeling package at least. I would do the free mod and lower your car, align it Z06 specs, get some nitto 555r II tires all the way around, and bolt on's. What year viper is it, and what mods are done? My intake and exhaust 97' has beat a 99 GTS in the straight away believe it or not!

Plus I would suggest better brake pads & brake fluid...you will need it at RA.
If you want to compete with the Viper (unless it is one of the old models) you will need cold air intake/heads/cam/headers & tuning.
Don't worry about adding power & beating your friend...enjoy the track, focus on the experience as a LEARNING TOOL, and be safe.

You mentioned that he's a "Formula Mazda diver". IMO the bigger advantage he has is in driver skill. Hey, a Spec Miata can beat a Viper if the Miata driver is experienced and the Viper driver is a rookie!
IMO here is where your money is best spent (in this order - in terms of best lap times for the buck):
Good luck! . . . Sounds like you might need it!
Dave
EDIT: I just noticed I misspoke on the front "toe-out" alignment - It SHOULD be slight Toe-IN!
IMO here is where your money is best spent (in this order - in terms of best lap times for the buck):
- Seat time at Road Atlanta. Get someone who knows the line VERY well to ride with you and teach you the line, breaking points, turn-in points, enter slow and exit fast, accellerate THRU the apexes, etc., and then do a lead-follow behind a fast driver who knows the line. Then get enough time on the track that you can drive it in your sleep. 3 days at $250/day plus gas, brake wear, tire wear = about $1.350
- R-compound track tires. If he's running street tires, R-compound slicks will give you a HUGE advantage - Or at least offsert his power advantage. About $1,000 mounted & balanced.
- 4-wheel alignment and corner-weighting (about $350). Corner-weighting will balance the car (equal weight on all 4 corners - with YOU in the car), making it handle closer to neutral (no over-steer, no under-steer). For track use, have the alignment set at 2-1/2 degrees negative camber up front, and 1-1/2 degrees negative camber in back, and slight toe-out up front. Those settings will greatly improve your turn-in and corner handling. But it will tear up your tires if you run it long-term on the street. So just have it re-alligned after you get your $10K!
- Hotckiss or T-1 sway bars ($450 to $850). But you already have that handled. BTW - do the supension work BEFORE you do the alignment/corner-weighting.
- Long-tube headers (Kooks, LG, or TPIS), 3" catless x-pipe, and low-restriction cat-backs (BB PRT's are great!). About $1,800.
- Blackwing or Halltech A/F set up (about $250).
- Heads/Cam/Tune (about $4,500).
- FAST 90 Intake & 90mm throttle body. (about $1,200)
Good luck! . . . Sounds like you might need it!

Oh, BTW - Your competition should be based on best clean lap time (no traffic to pass). If you run side-by-side, he'll beat you into the first corner. Then even if you drive better than him, your car handles better (thus you're faster in the curves), you'll never be able to pass him becuase the only place you'll be allowed to pas is on the straights, and he'll pull away from you every time you come out of the curves onto the straight aways.
Good luck!

T5 at about 105 mph and hit the inside gater with the left rear wheel. It tossed the rear of the car to the right, ( turn head look down straight - turn steering wheel to the right) rear tires caught, car staighten out and I guess I over corrected. Rear of car came around and backed into the wall on the out side of the track. I did not want to go back into traffic and attemped to drive backwards between traffiic and the out side wall. I hit the wall.
I watched my video a few times to see and hear what happened. Once I learned what happened I put the video away.
