1) Dont trust an organization I have never heard of. Dont know what type of timing system they are using (unless they are using transponders then mistakes can easily happen)

2) You dont have to be nasty, yes I do have reading comprehension skills, DO YOU? I questioned what they consider a "Race" tire because they dont list them by BRAND, some would consider a Goodyear,Hoosier and Kuhmo a "Race" tire and a Michellin Pilot Cup or Yokohama A038 a Street tire.

3) On the time sheet you have a link too, they dont have anything that references the cars on the time sheet to the specific modifications, at least that I could find.

I am not going to argue with you on this anymore. Bottom line, if it was a SCCA or NASA timing sheet I would not doubt the results.

As far as the original question you posted regarding the Z at Laguna Seca, a relatively stock Z should be considerably faster than a relatively stock S2k at LS, especially going up the hill to the top of the track where torque is very important. If I am able take my 350Z racecar there next year for the SCCA National I'll let you know what kind of lap times it turns...

 

Laguna can be pretty intimidating, it took me years to be able to run sub 1:30's there consistently (on GT3 ) can't wait to try it on GT4!

BTW SV use high quality timing equipment, they also have some very experienced S2000 drivers that drive agressively and push the limits of the car. If I can get my car a little quieter I will try and make it out there for there next event!

 

Top-level Spec Miatas have dipped into the 1:48's at Laguna Seca with pro drivers like Ken Dobson at the wheel. These cars weigh approximately 2300 lbs with driver and run on DOT-legal race tires. I've driven S2000's on the track (both kinds!), and I'd be surprised if a mildly prepared S2000 street car could go much quicker - even with slicks. It would be fun to try, though!

 

Yup, SV uses good timing equipment and the tire/HP/interior is of course done on the honor system

 

350ed,
exactly my point, who is to say what modifications each car has, it is not an organized and policed series like SCCA or NASA. The S2000 turning 1:43 has probably been lightened signifigantly and probably has a blower on it and I am sure an EVO with street tires can turn a 1:49 if it has 350hp-400hp.......
