What about a Boxster for Champ Car?

So, me and some buddies have been racing in Chump Car (now called Champ Car) for a few years. I joined the team after the race vehicle was completed partly due to my 20 years or so of track experience. In other words, I didn’t pick the vehicle. Anyway although we’ve had a few successful (i.e. finishing in a respectable position) races, the vehicle is not competitive. To further thicken the plot, we blew the second engine in two races a few weeks ago at Barber Motorsports Park.

So, we’re on the hunt for a different vehicle. Being a Porsche guy, I was pushing for a “well setup 944” but my teammates called that “anemic”. What about a Boxster? The 96/97 models are 500 points. In other words, no penalty laps. Gut it, put a cage in it (and transfer our fire suppression system, etc.) and go racing.

What are the pitfalls with this plan? I know some the early engines had issues, but I’ve been an air-cooled guy forever and “haven’t been paying attention”. It seems the brakes and everything else should be fine - especially given a couple of hundred pounds of weight reduction. I heard a rumor that someone entered a Boxster in the recent Laguna Secs Champ Car race but couldn’t find any info.

Ideas?

I race Champ Car as well (#32 1989 Toyota Supra) and have been planning my next car build for a while. Current rules favor a light weight, good handling, low value car (MR2, Miata) with an engine swap.

One thing about Champ Car, you can never count on the rules staying stable.

I have been considering a Boxster, but am concerned about ease of working on motor, and I think it will have to have some penalty laps for such things as an Accusump and better cooling.

Have you checked out the engine swap formula, though? Engine swaps are hugely penalized. Take a 1992 MR2 since you mentioned it. Swap in a 260 hp Camry engine a la Bill Strong and the resulting point value is 2386! That’s 189 penalty laps! In other words...don’t do it.

We are leaning towards an E46, but I think a Boxster could be “better”. An Accusump is 50 points, I think. I’d take a 5 lap penalty in a Boxster all day long...

I’m sort of fishing for some feedback from the spec Boxster guys. They should know the weak points intimately.

Siberian - do you know what’s up with the Cone Crushers 944? How are they so quick?

Check out the Biohazard MR2 with motor swap that is dominating the East right now. Don't know the specifics of the swap, but even with aero, he is in under 500 points, and winning.

The SC300 is doing well too and it's a heavy car like mine. I just don't have the time, money, and know how to make a front runner.

Damned if I know. I should have gone to mechanics school instead of college and vet med school.

I found a 99 Boxster in a field that I'm trying to get cheap. I have 2 tall drivers that might be a problem, which is the reason I didn't buy and build a turbo Miata.

Biohazard is the Camry engine swap car. They were grandfathered in before the new swap rules took effect. Doing his swap now gives you the 189 lap penalty.

I’ve driven Boxsters and have instructed in many and haven’t had a problem with height (I’m 6’3”).

The SC300s look fun (and are successful). I need to sit down on this cold Sunday and start learning the BMW alphabet soup.

One of my team-mates bought a E36 (1996-ish?) about 2 years ago, to turn into a ChampCar, so we could have "second" car when the Supra wasn't running, or when we finally killed the Supra. He has yet to get it running.

Meanwhile our Supra just keeps on going. It's only real problem is that it is so heavy.
