What pipes are you using???????

G'day all,

Just wanting to open a discussion on what pipes people are using. Which ones people have found better on various engines.

Why????......because I'm interested.

A list of who used what at the team trials would be very interesting.

HAY Brian. The PA-51 that I got from you works the best with the George Adrich pipe. Same with the Jett-50. I've tryed the aero three chamber and Windy's pipe. Both work. But not like the GMA pipe. More power, less heat, steady RPM's, and Larger Props three blades.
PA-51 I have over 1100 runs and NO problem. 17.5 inches 11,300, 11.3x4 bolly 65 foot lines. Same with the JETT-50

HI Brian
I'm currently running a OS .32/f on a Randy Smith pipe, it's my first pipe so I do'nt yet have it all worked out but it seems to have alot of potential, stay tuned(ha ha)

Matt had been using Randy's 4 chamber 61 pipe that has the stinger pointed down so you don't need the little "rubber ducky" thing on the end. After the Nats he switched to a 4 chamber 65 pipe (still with the PA61) set at 17 3/4 inches and was using a 13.5 inch 3-blade Bolly.

Now, as to why, that 13.5 inch 3-blade Bolly is why. Matt had been using a number 8 venturi on this combination, but switched back to a number 9 for the Team Trials because of the temperature range (65 degrees early morning up to 85 in the afternoon) and stuck with 5% nitro throughout the competition.

I know Ted was still using the Eather pipe, I don't know about David. Billy was using a Smith/Werwage pipe (or maybe just a Werwage) and Todd, of course, didn't use one.

For the PA 61, I am using the standard Smith/Werewage regular 61 pipe with the stinger out the back. This is the only one I have, so I can't easily compare it to the others. I'm pretty happy with the way it works, so I haven't been prone to experiment a lot.

For the PA40, I used the standard Smith/Werewage 40 pipe and the Bob Hunt 3-chamber pipe. I preferred the Hunt pipe, as it had less unload and less boost/brake. The Smith/Werewage pipe gave more power.

For the 40 VF I much prefer the Hunt pipe, for the same reasons as above. It may be that I just lucked into a perfect setup with it. The way mine is, I can run it exactly the same anywhere in the country and it always runs exactly the same way with only tiny changes in the needle. The Smith/Werewage pipe on the VF works, but takes a lot more adjusting, which could be a good or bad thing depending on whether you want to adjust it. The Hunt pipe runs one way, and if it's not the way you like it, well, too bad.

All of Billy's experimenting with different resins seems to have paid off. The earlier Smith/Werewage pipes used to be somewhat prone to leaking, but the newer ones (last 3-4 years) seem to be pretty much bulletproof.

Can anyone give me an idea of how the new 65 pipe compares to the Eather #6.

This one's in Ted's court. He is presently using the Eather pipe and has one of the new 65 pipes in hand to try. (Come on, Ted, put it on your plane and give us the answer.)

I can tell you that the 65 pipe is larger in diameter (like the Eather) but the stinger is aimed down so you don't need to add one of those "water hoses" to the end with the elbow in it that suck up the power. You need to add a few more head shims to the engine when using the 65 pipe because it does give a power boost.

The only question I have is, if the 65 pipe works so well on the 61 engine, is it, maybe, too small for the 65 engine?

Yes I'm very curious.

I run Jett/GMA 60's and currently use Eather #6's in my current 2 models. I'm in the process of finishing a 3rd and will need a pipe for it.

I wouldn't mind trying Randy's 65 pipe but the exchange rate of our currencies makes it an expensive exercise and I want to be sure of some sort of comparison before I outlay the cash.

What's been written so far sounds encouraging though.
