Just to keep it all straight.. maybe what carl is proposing is a good idea..
lets make sure we have a clear understanding.
Okay Let's go
This idea has ZERO bearing on the IMPBAs B Tunnel class.
True
This idea has ZERO bearing on the IMPBAs D Tunnel class.
True
This idea has ZERO bearing on the IMPBAs E Tunnel class.
True
This idea has ZERO bearing on the IMPBAs F Tunnel class.
True
The intent of the class is to open up new opportunity’s to sustain or grow the hobby of RC Tunnel Boat racing. This is driven from the COST associated with current motors available or lack of as well as a pre-emptive strike regarding the current declining state of Nitro Tunnel boat racing.
True (Declining in some places)
(this would be a good place to qualify the above “Assumed” intent)
Okay, see next
General: The intent of the Super Sport Outboard Tunnel Class is to broaden the racers selection of power heads and lower units through regulating the dimensions of the mufflers and their exhaust outlets.
This idea would eliminate from the IMPBA the class now called “B Sport Tunnel”
See Next
It would be replaced by a class called “B Super Sport ”
Renamed and with different restrictions but True. A legal Sport Outboard that you have today such as an out of the box O/S outboard, qualifies to race in the Super Sport Class just as it is with no changes to it because it is a muffled engine who's exhaust system meets the qualifications of what is described as a muffler in the Super Sport Class.
In that one could run any displacement correct nitro engine
True
The restrictions would be:
Size of the exhaust “hole
Diameter”. (do we know what size is?)
Yes, these diameters are taken from what already exist from K&B, O/S and Thunder Tiger.
The use of tuned Pipes
No Tuned Pipes Allowed in the super Sport Class. Mufflers are more tightly regulated than the existing Sport Class.
No restrictions on:
----
Carburation (can be any form of intake)
True
Carburation intake size (no restrictions)
True
Lower Unit make or makeup (no restrictions)
True
Muffler (qualified as NOT TUNED)
Correct or muffler make up (no restrictions)
Muffers are restricted to max length, diameter & exhaust outlet diameter(s)
Then.. added to the IMPBA roster would be:
Drum Roll inserted here....
B Sport Tunnel
name changed to "Super Sport Outboard Tunnel"
D Super Sport Tunnel
Added to Super Sport
E Super Sport Tunnel
Added to Super Sport
F Super Sport Tunnel <---- No "F"
Anything else I might be missing or need to be added?
Yes, I would like a cold beer and a pizza after I have done all this work for you...LOL
