multi engine nitro hydro displacement limit change

[Don Ferrette]

FYI- at the board meeting last night it was voted on and approved for one year trial to raise the multi engine nitro hydro displacement limit to 2.5 cubic inches total. The F class displacement limit remains the same as before.

cool don,

personally i think twins need to be unlimited cubes. but that is me.

thanks for the info

Chris we have to specify a max. displacement for the insurance carrier.

I'll bet Doc and Mark are scrambling to put two 1.0 motors in a twin for Atlanta. B)

Nah, 1.01RS from CMB I'll bet.

2.5Cu In, ehhh. As I recall, the class was multi engine rigger. That's enough cubes for a triple .80..........

Already had the piston & sleeves plus head buttons ready to go into the motors. LOL

i guess i better buy the 80 piston and sleeves for mine so i dont get lapped..lol

You and DOC opposed this change when you submitted the Twin proposal 4 yrs. ago along with many others. IMPBA growed up a brain here. I repeat like I said 4 yrs. ago. The safety margin remains unaffected with the 1.01s. I guess you will not run your Twin in F Hydro anymore, LOL, :lol: LOL, :lol: LOOOLL ......... :lol: :lol: All I can say is thanks to the gas guys that came rescued us Nitro guys out of the dark side here.

Jose you need to get your facts straight. I have never opposed the increasing the size. Remember I said the we need to make the class first and then increase the size when the time came around. Well that time has came around. The first e-mail I got about this had the limit set at 2.2 and I replyed back to say not to close it off and make the limit 2.5. Everyone was in agreement with this so now we have a 2.5 limit that should last for many, many years. Your right about running in F class. But I could build two Twins with 90's in one and 101's in the other. LOL

Triple 80s 64 oz of fuel wowzers. Ya might have to stagger them props

KOOL................NO ONE WILL KNOW the Difference if I have the 1.05,s in!!! :lol: :lol:

Two twins LOL :lol: LOOL :lol: :lol: :lol: ......!!!! Why complicate your life. The performance potential from the 90s and 80s is the same. Stay with your 91s. The 1.01s is just another choice.

Ha... the man said TRIPLE 80`s 2.5 total Now that would be a strange sound..... :blink: MEOWWWWWWWW

Hardly Believe more weight heavy about 20 to25lb :lol:

 

[PHM Racing]

I'm sure CMB may come out with some bigger motors and more to follow , now that the limit has gone up , time will tell

They already have, I think it's call the 35Rs.

"I'm sure CMB may come out with some bigger motors and more to follow , now that the limit has gone up , time will tell"

Yeah, right. Don't hold your breath waiting for that to happen......

The limit for F hydro and F mono (X class in NAMBA) has been and still is 1.8 so there was absolutely nothing stopping up to a 1.8 cubic inch single previously. CMB is not going to create a bigger motor just for one thinly (compared to other classes) populated IMPBA twin class. The 1.0 came out ten years ago to appease the "bigger is better" U.S. market and all they did (at that time) was to overbore the 90 sleeve and literally add thickness to the piston outside diameter to make up the difference. The original pistons were super heavy & you had to grind the crap out of the undersides of them to get the weight down. That motor and those that followed to the current 1.01RS are based on off the shelf 15cc motor parts that require only a p/s and head button change so the cost outlay for them to offer it outside of the normal NAVIGA based market is minimal. And just a few years back, CMB came really close to killing the 80 motors entirely since they were pretty much only run over here, the 15cc class worldwide supplied the strong demands for the 90 motors. Fortunately for us at that time Art from Tidewater, who was the CMB importer before Stu took over when he retired, talked them out of that and we still have the CMB80's.

CMB, like any other business, is going to play to what sells the best, especially in lean times like now......

Years ago a guy did a "triple 60", he didn't have much success for a couple of reasons. But a triple 80 would be cool to play with! The guy with the triple 60's had them mounted on solid mounts!!!!! Jeff Lutz
