Impba does not have a true stock 3.5 class and never had one. This is where a lot of confusion comes in. The Impba is basisly stock appearing with internal mods, factory carb and exhaust. Namba runs a true stock class it must be as it came out of the box inside and out. Namba also has engine teardowns after the races on this class. this is why Impba went sport b class to avoid this. In Impba we use go no go gauges to check the carb and exhaust with.

If you run the stock 3.5 in Namba you will be fine in the impba running the sport b class. But if you run the sport B class in impba and go to a namba 3.5 stock class you will be illeagle. politics are great ain't it! Oh well life goes on.

A lot of times clubs In the Impba have called the sport b class 3.5 stock a lot of people consider a engine with no tuned pipe a stock engine. It has only been the past 5 or 6 years that people have been using the sport B 3.5. I have club trophies with 3.5 stock and 7.5 stock on them. see ya soon Jimmy

A small clarification to what you wrote, a sport B from IMPBA will not be illegal in NAMBA if it's stock. ;)
 
Jimmy got it on the head.

THe sport class was started after IMPBA realized there wer eabout 4 different sets of STOCK rule around the country so Rod Gerhaty and Tommy Lee helped deveolp the SPORT rules we use today. Our present rule are as far from actualt stock as you can get. Modifcations can be made internally only on the engine. The lower unit can be modified per the written rules in the rulebook. An example of illeagal modifcations that have been tried in the past enlarging the Carb opening by making it oblong go /no go guage would allow this but a good tech inspector caught it and putting spacers between the muffler and exhuast flange also illeagal and machining swirls in the opening of the carb adn adding external oilers and fitting to the engine /lower unit on the K&B.

Basically if you can see the modifcations from the outside of the engine it's not legal!

TO find out what mods to the lower units can be made you must read the rulebook.

Now if a club wants a stock class they will need to print the rules on the race flyer and be prepared to have an expert engine person tech the engines almost every heat because some guys will switch engines for the second day of racing so they will not get caught. Had one gut that used to run a .29 for the first day and then switch for the second day. You coul dtell since his boat would run away from others on the first day and the second day it was running about the same as the other guys. There are some super good machinist out there.

Gabe,
You miss my point. The current Sport class was called Stock in the 1990's in D12 & D13 and beyond. There was no mistake to it with the name. That was the class name. It has evolved to Sport now. No piped motors and the only one available was the water cooled K&B so it was easy to distinguish.
I've had discussions like this and the bottom line result was we have what we have. Many people think stock, but in reality, that's not what it is. Before the IMPBA adopted the rules, many clubs and districts were running stock classes. From the past discussions, some of the reasons IMPBA has sport instead of stock is because:

  1. A lack of desire to perform any sort of engine teardown.
  2. Considerable variation in the parts within a stock K&B engine, making it nearly impossible for a person to really know what was stock.
  3. A desire among some people to tinker with the insides of the engine to gain a power advantage.
  4. Apathy among the general membership who might have wanted a stock class, but didn't bother to make their opinions known when the decision was made to go with sport instead of stock.
  5. To allow those with older K&B engines to mod them to bring them up to a level where they can compete with the OS engine (which is funny because now there are people modding the inside of the OS)
  6. Etc, etc, etc

It's always interesting to observe that some of the strongest advocates for sport instead of stock are those who have a vested interest in internal engine mods. I've discovered that discussions on this topic often result in significant abuse directed at anyone suggesting that we would be better off with stock instead of sport.

Anyway, the class is what it is. I've always felt a true stock class would provide better competition by keeping the costs down and providing a more level playing field. However, we don't have a stock class and due to all the modded engines out there, and the people who mod them, we probably never will.

So, perhaps it's time to get back to the race smack talk instead of sport vs stock?
 
I agree to disagree with you Piper Chuck. So, now that this has been beaten to death once again, and opinions have been stated, lets get back to it. :)

Toni, Mitchell, Steve, and the rest of Otto's Choir boys....you all suck.
 
Twisted,

What makes a racer a champion winning an internats or Namba nationals. One race and he is a US-1. Any newcomer who drops into the World Tunnels and wins a 40-60 boat field has my respect cause dumb luck is not in the equasion here. What other race has fields this large with the elite of their class. How many National champs and US-1's are in this race? Is their a tougher OB tunnl race on the planet?

Just my opinion

You can't win a race if you stay at home and everybody has a chance to win it all about finishing your heats
 
BINGO.....

Mike im so pround of you man... you HIT THE NAIL SQUARE ON THE HEAD with that one..

let me repeat what Mike said

"You can't win a race if you stay at home and everybody has a chance to win it all about finishing your heats"

Boat racing of all types has always had Championship Races. The old outboard world championship in Lake Havasu, the OPC Nationals that were held every year in Miami, The St. Louis OZ F1 race. Such events would crown a National or World Champion for that one race. We race all year for district point titles. Having a Championship Race for one division, such as outboards, brings together the best of the best. It might interest many of you to know that what we are doing in RC racing is exactly what lifesize boat racing has lost over the years and they are struggling to bring back. Looked at the entry list lately? Win a class at this race and you should be called a Champion.

Now what we need is a Smack Talk Champion! :lol:

The B-Sport Tunnel Rules Speak for themselves,its one of the biggest classes at most any race. And draws 30 plus boats at every Internats. Here in D-14 the series draws over ten boats at each race. LONG LIVE B-SPORT OBT Mike

mark, having grown up in miami in 50's & 60's, i miss the racing. used to watch at pelican harbor & later at the marine stadium. sure do miss those days. that's why this hobby excites me so much, i can connect with fast boats, & close competition. how about a wof mccall tunnel :ph34r: ? is it march yet, i'm ready to dive off into turn 1!

life's object is not to arrive at the end with a pretty, well preserved body, but to slide in broadside, and yell "**** what a ride!"
