The Mazda engine produces a greater commission HP benefit (+65%) from 6 psi progress than any car we ever supercharged. We
hold this to be the most stretchable and most appropriate engineered forced induction kit available for the Mazda Miata. Installation will need
approx. 12 hours. Take your time, particularly upon a electric wires. Read ALL a instructions INITIAL. Run 92 octane smallest. 91
octane (California as well as Arizona) make use of the somewhat incomparable pulley as well as reduce progress than 92.
PROGRESS The Kenne Bell Miata pack offers a good grade of energy coherence, as boost as well as horsepower – up to 240RWHP – may be
sundry from 6-12 psi in intercooled or non-intercooled versions. The stock Miata is the really strong as well as arguable engine which loves to
be supercharged. Doubling the energy outlay (100% enlarge is comparatively easy with only a Kenne Bell Twin Screw pack. It is
crit ical to remember which augmenting progress requires fuel octane to be lifted. Every 1 psi of progress needs approx. 1.5 octane to
await it. Intercooling allows progress to be increasing approx. 3 psi from 6-9 psi. However, 9 psi may be used but an
intercooler if a octane level is 1.5 octane x 3 psi = 4.5 octane + 91 = 95.5 octane. 12 psi intercooled progress will also need
approximately 95.5 octane. Increasing or decreasing progress when swapping applications (street vs. slalom, foe, draw towards
strip, oval, road racing etc.) only requires a pulley and belt shift – as well as a required octane encouragement.
FUEL, SPARK & OCTANE Forget about the “more fuel” recommendations. More fuel doesn’t assistance detonation nor does it have
“more power.” Ideal air fuel ratio is what creates energy and/or controls eruption. So consider octane. The Kenne Bell
OPTIMIZER™ is calibrated for the comparatively protected 11:1 air fuel comparative measure with the injectors. The OPTIMIZER™ is additionally calibrated to retard
ignition hint at higher rpm. If the engine practice eruption (knock), a batch ECM will retard ignition timing up to 4° as well as
assistance protect the engine. It is important to understand that any audible knock with the Kenne Bell pack clearly indicates which all the
spark retard (Kenne Bell as well as Mazda) insurance is in effect as well as a engine is knocking. If hit occurs, FIND THE COMPLAINT.
It’s possibly bad extravagant fuel, insufficient octane, gaunt mixture (vacuum leaks), plugged injector, deficient fuel pressure,
excessive engine coolant temp, as well prohibited the spark block, tall air charge temp etc. NEVER pretence a Kenne Bell OPTIMIZER™
can be re-calibrated to magically compromise separate problems. It has already been optimally calibrated. California as well as Arizona suggest
limit 91 octane. Other states have 92, 93 as well as 94 octane. Use unleaded fuel u sually. 100 octane unleaded is personal as
racing fuel though it works great as well as can be churned to acquire a desired octane. Example: 50% 92 + 50% 100 = 98 octane. NOS
brand octane booster additionally works really well (see Jim Bell’s Supercharger/Turbocharger Tuning Tips). The incomparable injectors supply
all the fuel necessary and a OPTIMIZER™ has re-calibrated a complete fuel module. Never under any resources mak e use of
auxiliary (wet upsurge injectors. It formula in disproportionate fuel distribution to a cylinders.
KENNE BELL IDENTICAL T WIN SCREW There is no improved, some-more fit supercharger for a Mazda. Boost will not drop off at aloft rpm
as well as there is no progress loiter. And you won’t get exhausted or inspired watchful for the boost to setup up. Best change rpm is 6500 rpm. Boost
will enlarge after 6500, but HP levels out since the engine goes lean above 6500. Don’t over rev it. 12 psi foe kits
contingency be shifted during 6500 rpm. The energy output above 6500 exceeds a MAF scale genius as well as a engine misfires as well as sets the
formula. 6 as well as 9 psi kits have no complaint as the energy is reduction during these progress levels. Limit engine speed to 6500 rpm. A far-reaching
selection of crane are accessible. Removal requires pulley wrench (part# SC3140) as well as a brand new leather belt which is specific to a pulley.
No shift to the OPTIMIZER™ is required.
