august fasttrack is out.
lots of interesting peices..
for you road racers,
showroom stock cars can "disable or remove" the airbags. you guys should like that one right?
In autocross, there is a huge reorg of the car classifications (again) leaving the EVO and STI to compete against the porche boxter and S2000. In SP, there are two very interesting proposals that are getting implemented
gotta love it, we have unlimited boost using the stock hardware for next season. I expect we will be bumped to BSP, but at least we can develop some decent power now.

unit.
b) No changes are allowed to waste gate(s) size, number, or location. No changes are allowed to variable-geometryturbine (VGT) hardware.
c) No changes are allowed to supercharger drive system pulleys. Belt tensioners
may be added/changed to reduce belt slip.
d) No changes are permitted to blowoff/pop-off valves.
e) Compressor bypass valves (CBVs) may be updated/backdated independently
of the other components of a forced induction system.
f) Boost regulation systems, either electronic or mechanical, and electronic fuel cuts referencing boost pressure may be altered or modified except as prohibited
herein. Boost pressure changes resulting from authorized changes are permitted."
Comment: With the increasing level of electronic controls in all areas of engine management, it is clear that it is very difficult to police boost management systems. Similar to a recent rules proposal regarding variable valve/cam timing systems, this proposal would effectively restrict turbocharger/ supercharger hardware to the stock parts, but would open up the controls, which, in conjunction with existing allowances on intake and exhaust systems,
will result in several forced induction cars making more boost and therefore more
power. The **** is aware of these potential performance increases, and will propose re-classing certain cars if a considerable performance gain is likely. Recent
new classifications of the Dodge SRT-4 in CSP, the Mazdaspeed Miata in ASP, and
the proposed reclassification of both the Mitsubishi Evolution and Subaru WRX STi
from ESP to BSP reflect some of these situations. Additional reclassifications may be proposed

How you conclude that we could have unlimited boost in SP?

I would think that the allowance above that permits modification of the mechanical boost regulation "system" would permit use of a mechanical boost controller to replace the factory solenoid.
