Stage 2 Intake and Tuning Results The flow bench is a great tool and so is the dyno but there are many things that are very different in the real world. For example the flow bench doesn't pull on all 8 cylinders through the plenum, (when you are flowing a port you pull backwards thru other ports) its not the full load of what the engine is doing. When tuning - one can see the amount of vacuum being pulled on through the MAP sensor. The reason we offer the stg 2 intake is to make the most possible plenum volume where the engine is demanding it the most. When the LS3s and L76s came out we were seeing much more vacuum in the intake than ever before.
Not all of them are home runs, but many times we can match the intake with the exact combination. For one to say that a bolt on car doesnt need a stg2 is just not a fair assessment. The FAST is going to be the Best manifold out there, we are merely trying to make a manifold that is the best for the dollar.
By the way we have NEVER SEEN A LOSS OF part throttle torque or full throttle power as a result of increasing plenum volume.
Take a look at this recent dyno:
2010 M6 Camaro full intake and exhaust, run 2 had a base tune in it, run 3 was the intake swap and the last run was the fully optimized tune with a little bit more spark advance. This is a very recent A-B test of a LS3 stock intake to a stage 2, performed on a dyno jet in S Florida.
Results will vary and each car is different, with this one performing on the higher end of the scale, but the intake was a large factor in achieving these results.
Here is a 07 A6 Vette - had a fully optimized Formato tune, re baseline the car and installed the stage 2 intake. Again, the increase in power is not simply a peak power increase but is significant through out the entire RPM range. Same day, same conditions, A vs B test.
Here is a 07 Z06 with the following mods:
Callaway CAI, Fasterproms Ported TB and stg 1 manifold, STOCK EXH manifolds, B&B Fusion catback, Fasterproms custom tune.
Run 1 was a baseline pull with all aforementioned mods, fully optimized.
Run 6 was Stg 2 manifold and a tuning tweak, more fuel.
