Hello all,
Hoping to learn a little about weight and the SLC. I've had interest in having a car built or buying a completed car for a little while now.
One of the things that's always surprised me is the ~2,500lb weight of the LS3-powered "basic build" SLC. When I compare to the Beck 904 at ~1,700lbs and some of the crazy Porsche-based V-8 track cars (ex - Porsche 912 912 | eBay) that weigh just under 2,000lbs, the SLC's extra weight doesn't make sense.
In both comparisons it's the SLC's aluminum chassis vs steel tube chassis and steel unibody - I'd expect the SLC to be lighter. I'd expect the aluminum DART motor in that 912 to weigh similar to the LS3, and an old air cooled 6 to be of similar weight to the LS3. I suppose there might be a 100lb weight difference in favor of the other two from the lighter transaxle, and perhaps 30-40lbs from the A/C system - but the rest is a mystery to me!
Anyone help me with ideas on where the extra 500-800lbs is coming from vs those other two cars?
Best,
John
