Those CMDi pipe mount extensions are machined from 7075-T6. I think the lengths of those are 1", 1.5" and 2", hole to hole.

Nice running boat in that choppy water Toru!

The correct muffler will make a good pipe better.

Finally! Congrats on your 135 mph speed Martin!

If the muffled pipe in fact had more back pressure. Some of my muffled pipes had more back pressure than the non muffled version, but some had the same or less. If I remember correctly, we made a small batch of AB 45 nitro pipes. Then on the first batch of AB 45 muffled pipes, the pipe builder...

From my experience European racing in second to none. It is the Best! At the Worlds you have electronic lap counting and timing. Eliminates confusion. Fast time eliminates one-on-one run offs. Professional officials who are not competing in the race. A well structured system of running heats...

Depends on weather or not it changes the back pressure. If it makes more back pressure, the tank pressure will be increased. Less back pressure reduces tank pressure. Different pipes volumes and cones angle effect the mixture too. Just be prepared to adjust the needle when making any kind of...

Muffled pipes make MORE power. I ran 126.3 mph with one WAY BACK in 2001. Header, pipe, and stinger design/size all matter. The smallest change to anyone part can have a very noticeable effect on power all across the power band. My advice. Try all the pipes you can....or go with what...

Ok,so Buckshot got the Bronze. I will correct my OP. Kjell's 16 year old SGX 45 obviously ran the quicker time! Congrats to everyone on the Podium. The Gold for Eric Costa of France! Eric and Kjell are the best of the best! To finish a close 3rd behind them is a big deal. Congrats on your...

Sad news! Tom and Cindy have always been the friendly and positive couple in our midst. Donna and I remember meeting them way back in the early days of our racing. Our prayers and condolences go out to Cindy.

Ties are decided by time....I think!

Congratulations to Team USA! William Shackelford 7.5 Hydro - Bronze metal (3rd place) Doug Twaits Jr. 27cc (gas) Hydro - Bronze metal (3rd place) Great accomplishments after racing eight grueling rounds with 8 boat heats.

Congrats to Team USA! William Shackelford 7.5 Hydro Bronze metal (3rd place) Doug Twaits Jr. 27cc gas Hydro Bronze metal (3rd place) Lots of great competition! Awards that are truly deserved!

1981-82 vintage. Tidewater sold those for just over $100. That was my first Picco engine.

If are asking about the black case/gold head 45 there is a chance the P/L from the newer engines may fit. For sure the disc and crank are not the same.

An Original Jaguar, designed and developed by Yours truly in 1994. The Jag was IMPBA US-1 Champion in "E" (.67) Hydro two years in a row (1994, 1995) with John Brown at the controls. The Jag set several new records during 1995-1996.

AWESOME STUFF!

The best fix is to mill down the rear boom block and also the front block if needed until the tub and sponsons are level. If you want to add the pads, they are 3/32" thick. Width is not critical. 1.0" to 1.25". Then just mill down the blocks until everything goes to level. The original SGX...

I designed the MAC 21 and a pipe to match it at the same time. That pipe became the "CMB 21 Nitro pipe" five years later! The pipe is much different than the OPS pipe.

Have a great race Team Canada and Team USA! P.S. 0 DNFs will get you into the Finals. Takes more than that to get Metal at the World champs!
