I figure the blower is probably optimized for high 9s and a 6.2 liter engine (never saw an efficiency map on it), I figure the aftermarket is doing plus 70 to plus 100 on a LT4 so dunno 12 to 14 PSI which has to be WAY off the efficiency map.  We are dealing with a temp rise in either case, either before the intake valve or mechanical compression.
I hope others with the actual build will chime in. I would expect the build to be very responsive and fun. |
I think that the maximum boost levels that most tuners recommend for this relatively small 1.7 blower is ~ 10-11 PSI - No more.
Again, lets have people with this set-up chime in with more information.
Thing is, that I would not like to impair the emissions requirements, by deleting the CATs and potentially fail smog tests.
Regarding intake: The stock inbox can be modified (I.E. Drill openings at the bottom): i would like to remain with a panel filter too - There has been no significant (if any) gains proven by using a conic/round shaped filter (I.E. K&N, Rotofab, Etc.).
Ported TB is already installed BtW (Soler)
