Greg @ VMC seems to offer a very nice 1915 engine making about 110hp. I assume that’s plenty for a 356 Speedster Replica which originally had 60hp back when Porsche designed and built these cars.
With the VMC 1915 engine you get the 4.12 differential with the highway .82 4th gear which should work well for cruising speeds at 65-70mph, and the 4.12 should deliver brisk acceleration.
Assuming the base 1915 with the 4.12, is it safe to assume that the 1,700lbs Speedster will be peppy and can achieve 0-60 in about 7-8 seconds?
With that said, how much more performance does the 2332 actually offer based on real world driving, assuming back county roads and occasional highway runs? And if you upgrade to the 2332 is the 3.88 differential required or can you stick with the standard 4.12/.82 gears?
Final question, is it safe to assume that the 2332 will run hotter and have higher oil and cylinder head temps? I know that Greg at VMC factory installs an oil cooler with electric fan, but is the extra power worth the cost, heat and potential headaches?
