100+ MPH

[Buckshot]

Hey Guys,

Just wondering how many of ya'll have run into the 100 MPH range, and with todays hulls and motors is it still only for those few that have an expert motor man?

I'm currently running an .90/1.0 SGX with a CMB 100 and it is consistanly running low to mid 80's. The set up on the boat is like Andy and John say to run it. This is the same setup that I heat race with no changes at all. The boat handles like it's on rails ALL THE TIME!!

I'm just wondering if the 100 MPH mark would be too far off for this boat since it is a large boat compaired to all the other "100+ MPH club" boats.

I'm going to run my new SGX twin with 2 MAC .84's hopfully this comming weekend for the first time. Do ya'll think that this boat is capable of 100 mph fairly easily? I don't expect it to run that fast right out of the gate, but after the motors get a few tanks through them and all the bolts are re-tightened, it would be nice to achieve this mark after chasing it for sooo many years.

What do ya'll think out there?

I am running a Mac 84 in a 40 size Eagle SG and I am hoping to break 100 mph at the Huntsville record trials. At the last trials there was a twin Mac 84 powered Eagle SGX that made several 106mph passes.

 

[Jay Stone]

Ask my good friend Will Gallagher how elusive the 100mph pass can be.

 

[AndyBrown]

LOL.......took Will G. a few tries to learn to Drive that fast.

Now that he's got that part down he's run well over 100 with his Twin MAC 84 SGX. B)

 

[Don Ferrette]

I've gone over 100 ( just shy of 110 actually) with two different SGX boats & MAC motors.

Boats that heat race at 100 are not the same as boats that set straight line records. The same props and engine that will push a Gas Sport Hydro to 100+ will run an Eagle at around 82 when setup for heat racing. Turn fin and rudder drag are big factors.

PS Mike Bontoft has probably made more officially timed runs over 100 in 2004 than anyone I know of.

Ask Keeley how elusive it is! ;o)

i personally think it is possible . just time right boat set up and propelller and a end less pocket? B) B)

Heck it's not that hard just look on EBAY! :lol:

As our 'ol buddy Joe Ingrao used to say, "it ain't as easy as it looks..." :blink:

 

[Preston_Hall]

Well, I think the number of people is less than 15 so.................................

 

[Eric Canto]

The Eagle twin with MAC .84's is a no brainer 100MPH boat. The question is not will it easily go 100, but rather, how far over 100.....

Have fun!

Hey Don F,

Eric is going to tell you how to go 100+ with your twin.

 

[Buckshot]

I think 100+ mph will come fairly easy for the twin myself but what about a 90 size boat with a 90 size motor? Corse you can shoehorn a 1" into a .12 boat and haul a*# but what about the real deal. Can a heat race set up be run at 99.9 mph or faster?

[Preston_Hall]

Just because a boat has two engines absolutely does not mean it is fast. As far as I am concerned, watching others has shown me that a single is definetly faster.

Also, it is a misconception that a big engine must be shoved into a small boat. If you can get a .90 to run in .21 hull then I would say that is a big deal.

Again, if 100mph is so easy then why is there less than 15 people in the club?

 

[scott bouchie]

You can do it with a big boat,I seen Mark Grim take the turn fin off his heat racer and go 117 mph! the problem with 100 mph is it gets to 110...then 115...then 120! and your never satisfied!......but that's the fun.

Preston,

I agree about the single verses twin to a point. I have not only seen it also but have experinced it at races with my rigs, not to say I'm some hotshot but I have out ran some good twins(luck plays it's hand my way from time to time ).

Although I have to say just like with street rods, drag cars etc. The BIG motor + small boat = very cool but serves one need-- Straight line speed and aceleration ( which is a great thing by all means).

Just wondering how many of those in the "club" have done it with a normal size boat / motor combo (excluding Twins) that could simply change nothing but the prop and heat race with the same boat & motor.

Just some thoughts, not a challange

Hey Buck

I'm not an expert in top speeds. I have been in the hobby for a long time.

I have seen twin boats and my opinion is that with a twin you might gain

5-10 mph and not a whole lot more. If you know hot rods and dragsters

as you mentioned you will know that a 10 sec car is very hard to make it

a 6 sec car. It takes a whole lot more to drop from 10 to 6 than just to add

another engine. If that was the case , then the dragsters would have two

engines to go down to a 3 sec run. I think a good light design boat and a good

engine and prop and a whole lot of running and setting up might get you there.

On the other hand I think every person in this hobby is thinking the same thing

and like Preston says ..There might be 15 guys that have done it.gone to 100 mph.

Dont be disappointed when your twin will only be maybe 10mph than the fastest

21 hydro. :blink: Just my 2 cents. Nick

 

[Preston_Hall]

Buck,

I have only seen 1 boat go from heat racer to record holder. This was Kentley's 90 Seaducer. It was heat racing at 70 mph and went straight line at 88mph I think. Only a prop and strut adjustment. Kentley's 21 Hummingbirds seem to be near record oval speed if not better. Too bad a good 2 lap time has not been recorded but this is also a heat racer/record boat. The boat John Finch set the E hydro oval record with could be a heat racer in my opinion. He built it for record trials and I do not believe he has heat raced it. I don't know of any 100mph heat racers except for maybe 1 twin somebody mentioned once.

I know the feeling of being a fast heat racer and think that with just a small step you could achieve very creditable speeds. My Crapshooter 45 was running 88mph in its prime while heat racing. It would slow to a crawl and step up to top speed with no problem. Surely 100mph would be attainable. Not so - disappointment. Oval record? It's smoking speed but just won't turn well enough to be the master.

Well I'm not an expert either in top speed hence the questions

Twin engine top fuel dragster running 3's. That would be a sight to see indeed!

Well with any luck I'll be # 16 soon

And I'll Be flat ass P.O'ed if my twin only runs 10 mph faster than my 21 rigger (when it's all said and done that is).
