Can some have a look at this plug.

That would be nice but these guys are probably burning 40-50 gallons of fuel an hour and the boat may hold that much or more. Where are they going to put another 50%?

Thats certainly a consideration, but I do believe the additional fuel volume would be around 30% with the E85 mix.

I don't know if our rules would allow E85 as they state "gasoline only", which I understand could be argued and falls in a very grey area. However E85 isn't available here that I could find and as Tuner mentioned we wouldn't be able to pack enough fuel. We usually race 150-200 miles per weekend, with legs being 40-70 miles each and we require all the fuel we can pack on the longer legs, we definitely don't have the payload capacity or space (21 ft aluminum boats, 650 hp and total weight not including crew or fuel is about 1600 lbs) to haul 30-50% more E85 even if its a little lighter.

The other thing is using ethanol based fuels in a marine environment can be very problematic.

Yes, for some reason alcohol luv water

And this .... a touch of salty language in this one, not much, videoed from the beach by Canuks w/beer so what can you expect, people having fun?

Nice catch Tuner, very few people know about our sport, its a little bit of an Extreme "Closet Sport".

Weekend update;

The only plugs we could get in time for this weekends race was some NGK TR8IX which seemed to work well as we had no engine issues, however we're still going to try some traditional style Racing plugs like the BR8/9's mentioned in previous posts.

To give you an idea of what can happen when you're racing in water that can be only inches deep in spots and hit a submerged rock at 105 mph, take a look at the attached picture and video of one of our friends racing in the same class as us this weekend. The crew is fine, just a little sore. This is why we use aluminum boats and not fiberglass, the aluminum absorbs the impact and deforms instead of exploding like fiberglass does. I have personally been in similar crashes at similar speeds and its like hitting a hidden land mine.
onboard video of the crash. https://www.facebook.com/photo.php?v=10153208789460377 You'll notice that when the boat comes to rest after the crash, they are only in a few inches of water. Its not a matter of if, but when.

Another video of an Unlimited boat that is turbine powered flipping at 130+ mph and fellow racers having to come to their rescue as some of the locations we race are fairly remote and isolated, thereby not allowing help to be close by through out the entire race.

Our isolated racing locations help to encourage (but doesn't guarantee) good sportsmanship, "gentleman racing" and for great camaraderie among the racers and for them to race (mostly) with their heads, not their balls.

Good. Congratulations on a successful event. How long were the WOT sections this time? Total race length? I know what you mean about being involved in a lesser known form of “extreme” motorsport. I have been to a few rodeos in different arenas and talking about them with some drag racers sometimes makes me wonder if I’m on high beam or low beam. “WOT for 10 minutes? You’re BSing.”

That smashed boat, that’ll buff out, all you need, is a MIG and a few sheets of aluminum, a few friends and a few cases of Kokanee.

[jet1]

Some of the legs were shorter than others but most of the WOT without any letting up was 5 minutes. When I say letting up I mean I would take my foot out of it a little maybe 3 or 400 rpm for 1-2 seconds just to line up better with a channel. The legs lasted between 17 - 35 minutes

Here is a pic of that boat. the bottom is 1/2 6061 t6 alum with the tunnels being thinner. Total loss.

We're having problems finding a racing plug with a resistor, we do run onboard gps, intercom and the MSD COP ignition control 6LS #6012, http://www.msdignition.com/Products/Ign ... Crank.aspx
Anyone have thoughts on if we will have any problems running a non resistor plug? The reading I've done says that running a non resistor plug "may" cause "gremlin" like problems in your electronics, ie. ignition, gps, etc.

Thanks again.

[Mark200]

From an electronics point of view, what I have read indicates that a fine wire plug, such as an iridium as your TR8ix, will by nature cause less radio frequency interference (RFI) which is usually what causes noise in electronic equipment, which can present itself as static in your AM radio or erroneous data in your computer equipment (including computerized engine control modules). This is due to a more finely focused spark compared to the fat electrode of an old school copper plug, so the theory goes... think basic arc welder versus wire welder. So it's possible you might get by with the fine wire plug even if it is not a resistor version (a commonly reported issue with certain automobiles is the introduction of interference-induced ECM malfunctions when the stock iridium plugs are replaced with standard copper plugs). Barring an check of the systems by a qualified electronic tech using an oscilloscope, you more or less have to go on trial and error. If you do wind up with problems there are other solutions, such as shielded plug wires, ferrite 'chokes' (which may or may not be advisable in a spark type ignition), external resistors, etc.

Have you got cops?
If not, you'll just have to use resistor ht leads so you can pretty use non resistor plugs

Use a MMT octane booster in your 100LL in a ratio of 1 oz. to 5 gallons. I use a 12-14 oz. bottle to a 55 (US) gallon drum of 100LL. When you go to get the #8 plugs, check the octane boosters at the store and see which ones are labled "Contains MMT (methylcyclopentadienyl manganese tricarbonyl)" and use it. MMT raises the octane of 100LL several whole numbers. It will impart a tan orange-brown color to the plug ceramic. Too much will look like a wet brick. If the plug is too hot and there is too much MMT it will look like a shiny glazed wet brick.

With the cooler plugs, 26° should be OK, compromise, 25°.

Any chance you would share the names of ones you know that have MMT? I looked at some today and all they say is ... Contains Petroleum Distilants.

You have to go online and find their MSDS sheets. They almost all have their MSDS list on their website.
