How is no filter going to add even a single lb of boost? This is a centri supercharger. Boost is more a measurement of engine restriction vs wheel flow (which is directly related to wheel speed). Given any reasonable restriction in the intake, the ONLY thing a better flowing intake will do is allow the centri to make the SAME boost with a little less HP drag on the engine PERIOD. How much HP will be saved? Unmeasurable.

A pancake filter like I ran on my Challenger could help just a tad:

That said the only help is a slight bit less HP needed to drive the centri. Boost is directly related to engine restriction and blower pulley size on a centri PERIOD.

ok...so hear it is... picked up 60 RWHP using a bellmouth...the position of the intake protects the procharger....I was a Gas Turnine tech for 26 years...never had any issue with damage....unless i leave a bunch of bolts and remove all protecive crap there is no worries about damage...as for the heat, simple fix...just use some heat shield plates over the headers.

Here, a completely optimized full race set yielded less than 1 PSI of boost at the end of 1/8 mile.

A pulley change of .15 to .25 will yield the same boost and need say 3 to 6 HP to drive. As I have already said, the yield is NOTHING on a street engine that is octane limited.

So your saying you tossed a bell-mouth on and saw 60 HP which is bout 3 to 4 PSI of boost increase.... do tell?

From this article and this is a system that has an intake free and clear of any stuff (not like a 6 gen install). 2PSI on transbrake, actually pretty impressive, (don't know how much RPM and throttle setting is used with a race transbrake) just don't think it is repeatable in something that fits under the hood. Even then the boost can be achieved by pulley change, a street engine is octane limited. Now if the discussion is should I run a bell-mouth on my race car with F1, it would seem so and the OP has a F1, I'll grant that. Just don't know how effective it would be at the current placement withing the engine compartment.
