what would win in a race around circle track? porsche vs BMW?




mma=life


so my dad owns a 1987 porsche carrera that at stock with new axel and a redone engine runs 205hp and weighs 2400 pounds curb weight.it has proformance tires on it. my friend who owns a 2008 BMWm3 thinks he can demolish my dads porsche in a circular track race. who is right?
are you joking the m3 weighs 3500 pounds curb weight and the porsche has a tighter suspension for faster corners....i say it would be close at the strait away but bmw would be ahead by a bit but back to the corners the porsche would dominate it



Answer
Sorry to be the bearer of bad news: The M3 would enjoy a massive advantage over the older Porsche. A Stock 3.2L Carrera is about the same or slightly faster than an E36 M3, and the M3s since then are much faster than that. And I think you are underestimating how much the Porsche weighs (should be closer to 2800 pounds for a 3.2L Coupe with the G50... more for a Targa or Cabriolet - I race in older 911s and regularly instruct for PCA and am very familar with the 3.2s)... but regardless, it wouldn't be close.

Given a good enough driver, on a road course like Laguna Seca, the Porsche on street tires could be capable of nudging under 2:00 per lap. The newer M3 would be ~15 seconds a lap quicker (it'd lap the Porsche even in a 20 lap sprint race with ease)... ,maybe even a little more. Even in the corners, the M3 will be better - while heavier, the suspension is 20+ years newer, and not based on what was a compromised design that originates in 1963 (as does the basic torsion bar design of the '87 911).

Around an oval, it would be even bleaker, because the one advantage the Porsche would have on the M3 would be related to the lighter weight. Taking transient handling and braking out of the equation (both of which would be highly effected by the M3's greater weight), the M3 would run away.

On a road course, the Porsche could compete with the stock M3 under the following conditions: moving up to 7" and 9" lightweight race rims, front brake ducts, adjustable anti-roll bars and dampers that are at least as stiff as the optional sports package of that era, and Hoosiers or similar R-comp tires; early 911 headers and something similar to the early factory sports exhaust would help the engine breath better, and a brake bias valve to put more to the rear (and an LSD if the car is not already so equipped). And then just get a couple hundred pounds of weight off the car! This would help the 911 regain what it would be losing in the corners, and regain it's straightline losses under braking (especially as the laps added up). That would make it close... at least until the M3 put on sticky tires and again ran away into the distance.

And around an oval, given the difference in top speed between the two cars, there wouldn't be anything short of an engine swap and change of gearing you could do to the older Porsche to get it on pace with the newer M3.

The only likely scenario where the Porsche is faster is if the skill levels of the drivers are vastly different... a fast, skilled driver in the Porsche would easily lap faster than a novice in the BMW (then again, a skilled driver in an old Miata will lap faster than a novice in a race prepped Ferrari).
