Gary, if D is shrinking, just put that euro SC engine in your D car and race with all the cars in E !

The Werkstatt Cville Spec Box ran GTS-2 in NASA. Can use Hoosiers.

GTS-2 is correct. Min weight for SPBOX is 2650 (w/drover). One SPBOX driver ran NASA last year and had to add 50# of ballast (dyno was 192 hp). I believe that he ran the R888 and was still a second or so faster than the rest of the GTS-2 class in Texas.

2650 is bottom number Scott, I would figure 2700# would be where most run to be safe at the scales.. At 2700 they can run 186HP/180TQ and just make it in at 14.52.. that's what I will tell my dyno operator I want.

Just to alleviate any confusion
Sp1= PCA equaivalent to 944 Spec (PCA rules mirror NASA 944 Spec rules)
Sp2= 944 Cup. SP1/Spec cars can also run here at a lighter weight (yes this is confusing)
Sp3= 944 SuperCup.......
Boxster Spec sounds like fun. Still one buget level up/out of reach from a 944 Spec car for me. I'd be interested to see how much faster they are on the same track.

My car is set up to run in the 944 SuperCup series and I had the opportunity to run with a couple of well driven Spec Boxsters on the relatively tight VIR North Course last year and it was a hoot!
Eventually, I was able to pass them but it wasn't too easy.
On the full course I could stretch my legs more and it wasn't as hard.
I would think that the Spec Boxsters would probably be faster than the regular 944 specs due to the higher HP and better better geometry.

Here are some #'s from the start of my SPBox build as a totally stock baseline, this was taken a week after I purchased it. It should be noted that the dyno #s should really only be compared to this car on this dyno, they are not a NASA dyno station.

Out West the SB's are 3 seconds faster per lap at Willow Springs. In the NASA Nationals, the lone SB running in GTS2 was 6 seconds faster than the top 944 spec, and 3.5 seconds faster than the top 944 in GTS1.....

Not affiliated, and I don't know about the damage, but if anyone is potentially looking for a track candidate.

Racing "Cheap" compared to running a GT3 street car? please explain.
