OK - Preliminary results are in, here's the deal as I changed the tests a bit:
Test #1: Level ground (paved) 1/8 mile GPS speed, single driver, pedal mashed to floor. 86 2PG stock w/no governor 18.1mph, 86 2PG with BV24 Carb and stock exhaust 19.9mph, 86 2PG with BV24 and 1988 Exhaust 23.0mph .... Control cart (1988 stock no governor) 23.6mph ...
Test #2: Uphill (groomed grass) approx 100 yards from dead stop. 86 stock 12.0mph, 86 with BV24 carb 13.1mph, 86 with BV24 and 88 exhaust 14.4mph ... Control Cart (1988 stock no governor) 15.5mph
(NOTE: Uphill tests may be a bit decieving in regards to the control cart as it has an HP3004 belt and *does* take off a bit faster with more torque)
SO - there it is, bolting on a 1988 carb *does* add a bit of "oomph" to the stock 2PG, but coupled with the HO 1988 exhaust it's a very real and noticeable difference. The clutch on the 86 seems to downshift way too fast, so I'm thinking I may have an issue there too with the hill climb comparison (along with the shorter belt on the 88 as mentioned above) ...
Just for fun, here's a shot of the kids, the 86 is in front :)
