Old thread just wanted to say one thing, no such thing as a freak car, only freak dynos. Take all your freak cars to the drag strip and none will trap what the power indicates it should.

320 rwhp and trapping 108 with a basically stock 110,000 mile ls1 intaked car blowing through a stock clutch

car now traps 110 consistently in 90+ degree weather and about 233% humidity, havent gotten it out in decent air yet, added longtubes and tsp duals, still untuned, still running an ls1 intake, just lid and exhaust. i figure that is about a 20 rwhp gain in the heat vs good air, should trap 111-112 or so come fall.
I don't think it is a s much of freak cars rather than miscalibrated dynos and better drivers with good air. Back in 2001 my car had 147 miles when I took it to the track on the second day I owned it. All stock to the paper filter and not adjusting tire pressure. resulted in 8.47 @ 87 mph that's with an auto.
Now I know these cars have mileage on them now, that is why lite bolt on cars are the running the same times as I did years ago. Realistically you can't really compare them as freaks as they are 7-11 years old various mileage and most of you are not original owners, an do not know the care given for the car. 147 mile car then may be within the power possibilities of a lid exhaust car with 50k miles today after all of the carbon and wear has taken place over the years.
Dynos are just a tuning tool track times are close but varies on track prep D/A temp driver skills and condition of the car running car EX; condition of motor, trans, rear end,shocks ect.

Sounds like you just dyno'd on an incredibly high reading dyno. It should be trapping a lot higher than that if it has 458rwhp.
Do the math its all about power to weight ratio. If the car weighed 3500 pounds it would be alot faster. I thought the dyno was reading to high but when the car was weighed in race trim vs. the times it ran the math works out.

a friend of mine ran 12.7 bone stock.(F body) we figured his car was a freak. no dyno numbers. his car is far far from stock these days. sure, hes a bit of a wheel man. without calling him to ask, i think his mph was just under 109
higher milage car (within reason of course.. not a 150K mile turd) should be faster than a 147 mile car. your rings were just beginning to get acquainted with your bores at that point dude.. as the motor wears some it requires less energy to turn, and better cylinder seal will produce more power.

never been on a dyno,guessing 340 to the wheels ??????
I wouldn't call it a "freak" since most of the 98 (F-Body) LS1's seem to dyno well. Making the same kind of Horsepower at the Rear wheels as GM rated them at the flywheel (305 hp back then).
My 98 (F-Body) LS1 dyno'd 316 RWHP with my electric cutout's closed, and 323 RWHP with the cutout's open. The motor is stock expect for headers needed to make the engine swap fit, and having someone remove the TQ Management, EGR, VATS and stuff from the factory GM "tune".
vs. the times it ran the math works out.
