AA 45 vs NR 46 DD

[Duck899]

Ask Hobbs, I took it out of the box, bolted it in the boat, ran it twice in tweak time and raced 4 heats.....box stock. Won 3, second in the other cause I jumped the start.

Would you mind posting a pic of the AB45 black pipe

Running an AA myself, in a sport-40 always looking for the little extra

Rick,

The AB black pipe is a muffled vervsion of the current CMB 45 nitro pipe that many are using now. The muffler can looks like a small version of the black AB 67 muffled pipe.

I ran a macs products 10cc aero nitro pipe in a sport 40 with the AA a couple years ago......never tried the AB pipe in a sport 40.

Gotcha,,, Thanks Andy.

As we discussed @ SOWEGA, my setup didn't like the CMB nitro pipe. Go Figure??

What pipe is working best for you Rick?

Mac's 7.5 pipe

I ran the Macs 10cc aero pipe #1160 and aftermuffler in a mutt sport 40 with the AA45.

 

[David Murany]

We run the AA 45 pipes and they work very good. They have good sound, rev a ton and are real forgiving on the needle . They work best for us at 9" here in Michigan. My dad runs the AB 45 pipe that screws together in his sport 40 and the boat hauls.

 

[David Bryant]

I have run both engines. The AA has better power than the Nova. I raced one last weekend in an SGX-2 and it was the fastest boat at the race. However I did take 2nd overall to my son Jason who was running the Nova in an SGX

hey Andy, can you post a few images of your .45 SGX2 and Jason's SGX. I'd like to see your set-up's.

 

[Andy Brown]

Hi David,

The X-2 I ran belongs to Roger Hooks. We sold Jason's SGX to Glenn Quarles. There are many pics of the 45 SGX on the cmdracing site on the Eagle SGX page. Click the links on the "ready to paint" SGX. Those pics are how we lay out everything. If you are needing set up measurments and angles let me know.

I ran the Macs 10cc aero pipe #1160 and aftermuffler in a mutt sport 40 with the AA45.

That 1060 pipe will normally pull more prop than a regular 7.5 pipe. cup pitch and size. That pipe rocks on a Mono.

 

[El Zorro]

Best unmuffled pipe I found for a .45 engine was the MACS 8.5cc aero pipe. This was MANY moons ago. Bet it would still work well with an internal stinger.................

I check that out, thanks!

It's been over 6 months since any discussions on this thread and allot of fuel has been burned and races won since.

I am starting to build a Zippkit 45 JAE; I have the same quandary that this thread is about. What motor to start with, AA45, AA45 LoPro, NR 46, NR 46 DD, or CMB 45 VAC? I know service will be great from Al, Glenn, and Stu (thanks guys), so that is not an issue. It is good to have choices, but I have to make a choice and would like to hear some others experiences.

 

[anthony_marquart]

I have an AA that I have not run yet,.. I have not run the NR45 either.. but all my NR21 are REALLY top quality motors.. I'm sure the 45 will be no different..

 

[Samuel Hagan JR]

I also have a A/A 45 I haven't run yet.

I do not think you can go wrong with any of them. I was faced with the same decision earlier this year at the time the 46DD was on sale for $440 and the 45VAC was $520

( I was not looking at the AA) so I went with the nova.

Second trip to the lake this weekend ( first trip had fuel issues) I was very pleased with it. I did not have any means to check the speed. but it was faster than the CMB 45 cam (purple head) motor it replaced.

 

[anthony_marquart]

I know some guys think it's worth it but man,.. $520 bones for a 45 boat motor,.. holly cow it's no surprise we have a small contingent! Thank god for the trusty NR 5P!!

2 NR 5P for the price of a 45, now there is an idea...I wonder how many gawkers you would get showing up to race D-Hydro with twin .21's...It would cost more in the end with props, pipes, tanks....but it would be cool.
