I would just like to know where the performance gain is over the SPP carbon pipe. That's all I want to know. If you make the Cooper Pipes again they should sell good because a lot of people do seem to want them but nobody can tell me why they are better.

Carl they are the best performing pipe I have tried on a 21 OB and I tried many!!! Never had the chance to try an SPP though. I like the Cooper, thats my story and I am sticking to it!
 
Im in for at least two times 21, 45 and 67 outboard. Probably more
Joernnnn,nnnn
I can make the pipes, in .21, .45, 67 outboard sizes, the problem is, the .67/90 pipe is 13 inches long ,OAL, when added to the header length, it may change the balance point of your boat considerably, making the boat undriveable?????

My SSP measures 13,5 incl the muffler (maximum length)

The Irwin pipe performs fairly good even though it is made very short.

However I will start with two of each pipe if you gonna start production.

They are a very smooth and forgiving pipe compared to the SPP and possibly easier to setup to go fast. They come "on pipe" smoother than an SPP, but an SPP is more than likely superior in all out power.

A cooper 20ob pipe revs to the moon and sounds and looks great doing so...SPP are great if setup to suit you, your hull, your props and driving style...they dont look near sound near as nice...which is half the battle, right? :)
 
My experience with the SSP on 21 is that it kicks in very hard at a certain time, wich in some situations can be a little too much. However it has tremendous high rpm power.
Mr. Van Houten, you better dig out your Cooper collection and make your own experience on your current set-up as peoples set-ups and preferences tends to be very individual.

I will dig them out and give them another look. I like to test anyway. Keep us posted on your progress with this new pipe.

At what point on the track are you seeing a performance gain with the Cooper Pipe? Is it carrying you through the turns stronger, is it coming off the turns harder, is it pulling down the straights further before it peaks, does it stay staged better, is it pulling more pitch or is it doing all of these better for you? I ask these question because I have 3 or 4 of them and they are somewhere in a box in my shop and I am not sure exactly where they are because my SPP has shown to be a better pipe on my setup. I'm not trying to derail your thread because I am sure that if you build them again you will sell some of them. I just want to know what performance people are getting from the Cooper pipe over the Carbon pipes? It's a good pipe in my opinion but is it really better than the SPP carbon pipes? I am just curious to hear what you are seeing...

Carl if you don't want them I will take them off your hands... lol

I'll keep mine for testing. Sounds like they will be recreated soon and I'm sure there will be a lot of people ordering them.
 
Cooper had a real struggle getting quality castings made for the 21 outboard pipe. That’s why no one makes them. I talked to him at length about this when he was making the s pipes for me

****,That issue already exists with the 21 Cooper outboard pipe, at least with the two I have in possession and on the hulls I’ve run them on, due to the weight of the pipe. My gadgets,Irwin stampers, Silver Bullets, and SPP .21pipes all weigh very close to two ounces with the mount wire attached not including header or coupler. My Cooper’s both weigh in at about 6 ounces. That extra weight hanging off the transom needs to be compensated for to get the boat to handle properly. Whether used to make bullets or tunnel hull balance weights, lead is a fantastic equalizer. Kris’s description of the Cooper mirrors my own experience with these pipes, a very wide,smooth, power band with lots of revs. They sound cool, without being objectionably loud, and look good doing it.
 
There is a reason the Cooper is hoarded by outboarders. The weight is an issue but still a great pipe. "What IF" we challenge **** to explore making this design in Carbon Fiber? Or has it been done elsewhere?

I think it sounds like a great idea! Come on ****, take the challenge head on!
 
I sent my email off on the weekend I would like :

* One .21 Pipe

* Two .45 Pipes

* One .67 Pipe
