jadkar said:Wow!!! very off-topic but reading all these posts makes me feel really poor
I waited 16 years to be able to drop 35K into my little CRX and you just built the NSX to kill all NSXs because you felt a challenge??
I'm not worthy :wink:
Scot said:$35k into a CRX????
You can can build a H1 S2000 for about $25k....out of a theft recovery, Salvage title, etc...

A few reasons come to mind; 1) The later the season, the more people drop races because of diminished point possibilities; this was also a single race vs. the dual format. 2) Its been really hot here and even in consistent classes like SM, the times are down a second + with the same tires. 3) That brings to mind another issue; the Road Atlanta surface isn’t getting any newer. Using Roebling as an example, it went from so grippy that it could ruin tires in a single session to almost unbelievably slippery in a very short time (About 2 years). 4) With respect to H1, didn’t they go from open tire to Toyo? I know that the Miatas ran mostly in the 1:49s that weekend and I think I recall the track record being 1:44. Better weather during the AARC and Hoosier tires are worth 2 seconds.
RacerX-21 said:1:29 is a lightning fat lap on 275’s… that’s what the World Challenge cars are doing at Road Atlanta, I only hope I can run that fast after I sort the car out. The fastest/winning GT-1 ran a 1:33.8 and has 13" wide tires front and rear, they make over 750 HP and the one-piece body is esentually a big wing. The fastest T-1 at the Road Atlanta event last weekend was a 1:39.49 with 315 tires. I will be happy with that on used 225 and 275 tires. I raced the T-1 champion at Barber in 2004 while testing my 275 RW Cup car in SPO (He won the Southeast championship three consecutive years) Guess who won at Barber?
Go back to your slot cars
RacerX-21 said:A 125 hp go-cart would kick all of our asses.
Yes I would agree with this estimate. The GAC NSX with that rubber would be capable of these times with the right conditions, and the GAC car is only about 50 lbs lighter. That was my point Rubber, Brakes, car type changes everything. And assumptions are just that.Brian Bailey said:I should add that I suspect Rob is being overly cautious in his assessment of what his NSX will do at Road Atlanta. Whats to be gained by saying the car will run 1:25's, even if it will, if its only going to take 1:35's to demolish the HU field? All you'd do is run the risk of hurting the car by trying to prove a point.
That said, DAL's GAC prepped NSX should be more than capable of running in the mid 1:30's at Road Atlanta. I would venture that car would easily turn between 1:35 and 1:37's with a decent driver without too much trouble, maybe a little faster with the front wheel change they made after I left the team late in '04 which from conversations with them greatly helped the handling of the car.
This is based on times I turned in my PCA E-Class 944 Turbo at that track and the relative differential I observed between the GAC NSX and my 944 Turbo on the tracks where I've driven both cars (VIR, MSR, TMS, TWS, Daytona, Phoenix)
Given that, with a hundred or so less lbs of weight, none of the suspension restrictions we had in GAC, a lot more tire, a lot more aero, and a TON more horsepower, realistically that car should turn laps in the mid 1:20's. But again, why should he say it could or even try unless there was a need? Until another HU car shows up that can turn laps close to what that car should be capable of, there's no reason for Rob to push it even a little bit.
Having only skimmed the HU rules, what I'd like to see is someone take an NSX build out pro-level suspension, install a Comptech SC, a vented hood, and the Type R rear wing. Lightweight, simple, and should be reliable, that should make for a very fast HU car that should be able to run in the low 1:30's at Road Atlanta (might be able to break into the very high 1:20's with sticky tires but that might be a stretch) with no issues. Hmmmm, wish I still had my NSX, that'd be a fun project.
Brian Bailey said:Ummm, did you mean a 125cc kart? A 125hp kart would first of all be completely undrivable, though if it were possible to keep it on the track and put the power down, it'd have a power to weight ratio that would scare the crap out of just about anyone short of an experienced F-1 pilot (230 lbs, thats what, a little better than 2:1 or so). YIKES!!!!
But yes, a 125cc "shifter" kart, properly geared, would kick a car's tail on most tracks.

RacerX-21 said:You never told us you went to Phoenix before we went with the Cup cars.
RacerX-21 said:Use Cory’s times as a perspective with today’s track condition.
RacerX-21 said:Yes cc. I here that Eddy Lawson and his unlimited 250cc cart beat all the 4-wheel track records at Lagua including the F1’s. The only faster recorded lap was with an 1100cc bike.
Brian, what are you racing now?
Brian Bailey said:Don't you mean 50 lbs heavier? The GAC car weighed in at 2730 with the 3.0L. Didn't yours come in at 2680 or thereabouts?
I did, at 1:30.x, he was a few seconds off what a 997GT3 in Rolex trim will do at that track. Heck, a stock 997GT3 will run 1:30's and his is far from stock at this point. Also, knowing Cory, he was only doing what he needed to do to win. One thing he always does, brings the car home in one piece.
RacerX-21 said:I think the GAC car was with driver, wasn’t it?
This was his Rolex car and we were talking about not being sure if his best time of 1:29 would hold up to the other Time Attack competition.
Brian Bailey said:GAC is car only, as is the Rolex series. Most endurance series do it that way so you can't gain an advantage with a light and a heavy driver.
His Rolex car should definitely be capable of better than what he turned. A stock 997GT3 Cup will turn in the 1:27/1:28's and the Rolex car is a couple seconds faster than that. Heck, stock 996GT3 Cups were turning in the 1:28's at Road Atlanta the last time they were there and the 997GT3 Cup is at least a second or so faster than the previous model.
Even so, in a Time Attack, that Cup Car is really over-matched as its a real racecar built to a specific series ruleset. Unless the Time Attack rules have changed, there really aren't any, just like in HU. In a run what you brung situation, there are a TON of cars out there that would destroy a GT3 Cup car.
