[Syty] Would a Sy/Ty do good at...

Right off the bat 10 gallons in a fast SyTy would require a sumped tank.

Obviously the lack of high boost would affect the top end of motors, however
I wonder how 'slow 'the high 8's, low 9's  Sy's would be running with low
boost.
How high of boost could they run on 93 octane? 15 psi? 17 psi?  As far as I
know the really fast Sy aren't running really big boost numbers (They are
all under 30psi and closer to 25psi)  Engine coatings could help with
detonation as well as water injection, thought I suspect most of those truck
utilize them already.

Even with Vortec and race heads we obvious don't have the
best combustion chamber for detonation.  Stock Evo's peak at 21psi  and
settle to 17psi.  I think with aftermarket tuns have them peaking 22-23
psi and running 19-20psi on pump gas.  They aren't running low timing like a
stock SyTy either (14 degree).   Fortunately SyTy do a have a
relatively good amount of displacememnt for factory turbo motor, however
with an endless choice of motor in a compettition like this a turbo LS7
would have a huge advantage.

I think one of the fast Sy's could place in the list given the prior
times.  The only race SyTy is going to kick ass is if the require real full
depth street tires and don't allow drage radials..
