Dave,
Here goes... roughly in your order :->
I would not say that 4 strokes suck, but they are nothing special either.
I've gone and asked around to verify that I was correct in cautioning people
on 4 strokes needing dry sumps.
You can add that expense and the dry sump's extra weight to Jay's 50#
estimated overall extra weight for a 4 stroke
The Wests that CR mentioned still lose R1 motors. One lost 2 motors at one
event.
In SCCA homologating a car only applies to the chassis. There is nothing to
keep one from using a dry sump if the drawings submitted showed a wet sump
motor. Not sure what the homologation routine is in IMSA.
Phoenix Race cars designed their new F1000 chassis to accept a wet or dry
sump motor, but they say one would have to be a slow driver or penny-wise
and dollar-foolish to run a wet sump R1.
Every race shop I have spoken with says any motor with oil that must be
recycled from the crankcase instead of bring burned needs a dry sump if the
car makes much more than about 1.2 G.
(FF1600 is at 1.6G). Not to say someone may get a really well designed
baffled sump and accusumo to work-but I bet it won't work everywhere nor on
all motors. Gven a long enough corner, all accusmps run out of oil.
Shifting is OK but nothing special either.
If gear ratios are to be stock-then I can see people doing engine swaps
between different brand 4 strokes depending upon the track.
Probably should settle upon one brand and model 600cc motor.
Shocks are good to have to improve safety, also good to learn on for those
with real pro class racing ambitions. Probably more important to understand
than moving a gearshift lever.
IMHO below-not official view of MAC:
120 HP should be the driveable target HP for Vees.
There have to be some reminders on limitations on the 1600cc 10:1 setup
with its non-stock valves and more carb choices so that it will not be
clearly superior to the 1915cc 9:1 single carb, stock valve choice.
The present SV rules plainly do not allow any chamber work and this should
not be changed IMHO. The larger 1915cc bore does not inherently unshrould
the valves. The shrouding is from the deep chamber sides next to the
valves, not the bore.

Chuck,
Still alive, just nothing to bitch about at the moment. I'm sure you could
start something, maybe like... 4 strokes suck, shifting sucks, shocks
are a waste of money, and the new solo vee's will make 155HP!
....... ducking till Monday.
