Stiegemeier's Recommendation with our ported blower -A 2# Lower is Fine- But never use a 4# Lower it causes excessive heat build up and power loss, also rotor flex and case rub can follow.
I had stated earlier a 3.0 Upper with 4# Lower would be 16#s boost and ok-Well it was Assumed that a 2.93 upper and 4# lower is close to the same and what would be the difference-Then the next guy would figure more is better-That is not always the case. At up to 15#s of boost there are no fuel mods needed- Making tuning not so difficult.
At 16#s boost you will need a MAF extender ,BAP, spark plugs and after time a upgraded clutch-Making tuning more difficult.
At 17#s of boost you will need All Fuel Mods Big Air MAF, Focus Pumps or BAP,60# Injectors, Bigger Cooler, spark plug specific,selective fuel, Headers, CAT Hi Flo or Delete Uddated stronger clutch-Making tuning very difficult.
More boost more Heat when engine sensors read something unusual the react in a safe position-these areas must be datalogged and addressed individually.
To comment on my statement about boost I realize there are some out there who run 17#s boost very sucessfully. These individuals have worked very hard to gain the knowledge and experience to do this along with untold expenditures. I can not and would not expect these Cobra Warriors to pass on the recipe for Hi Boost Power.
These combos need many fuel mods and accessories- The biggest factor being an Ace Tuner. If your area is anything like ours- We now have 5 new dyno shops (within the last year) in a 5 mile radius- They are just starting their tuning learning curve.
