Test

All I can say is you can't expect to be fast out of the box with new everything without a lot of testing. This even holds true with stock equipment.

Your pipe is wrong. I think you want it pulled all the way up for max speed, all the way out is for punch... if I remember right. You pull the pipes up for max speed, and dump them back to slow down......

That might be your problem, unless I misunderstood your 2" back and fixed position.

I also feel a lot of people have false expectations of simply buying a pipe from anyone and bolting it on will put them out front. This is only part of the equation. Boat, motor, prop, set up has a lot more to do with it. But you still need a good pipe to make everything equal success. Lee makes a very good one.

Thanks Dave, you are right I have great power thru the corners and off the corners and then it has no more so we will go back to the pipe against the header flange and work with the new props. I am also going to trim some off the air traps since they are deeper than usual just so that I would have something to work with.

This year over here has been terrible for testing or anything else. We have had record rains and most rivers have stayed real close to flood stage for over a month.

I have been keeping notes on everything so it should help. Lee has been giving me ideas to try also so we will keep at it. I drove a kneeler for the first time this year and I am still hurting so I need to get the laydown going.

I hurt after every weekend, even when I don't go on my head. Maybe I need a laydown too?

I feel so much better when I just stick to just the laydown.

Daren, yes most folks don't need to MOVE lees pipe they just move themselves. My feet already touch the transom and it is impossible to slide back and forth in a laydown. So I have to work more on the set up be it boat, motor, exhaust and props.

"Daren, yes most folks don't need to MOVE lees pipe they just move themselves"

......what????????? the pipe stays fixed to the header, it does not move at all..............a short spring secures it to the header..........maybe the boat setup is not correct, but it ain't causing you a 15mph loss!!!! Those props look good, so I am willing to bet you the problem is the motor.........you could slide it slightly in the turns, if you are losing speed, but not much.

[blueskyracer]

Next race the 4th of July Mike Sattler is going to work with us and Josh Harnack to see if we can get both of them going. I guess we need to hope testing does not get cancelled again.

As far as the motor it was brand new last year and was only used 6 for 6 races and was fast. I will check compression when I get it out of the trailer in an hour.

[blueskyracer]

Compression is 120 on both cylinders with rope pull and snap-on compression gage. Just checked it. Upper spark plug looked just like new and lower plug was very light brown.

So what are PM's. I could guess but this is a family site

I thought you were refering to a part on the motor. Da

Fixed Pipe

Yes, like I said, if you are running a fixed pipe, you want it all the way pulled up for max top end.

I also think you should slide the pipe, I know a lot of people around here slide the pipe or pipes on a 302, and they hold the National Titles...... Vanover slides his on the 302, Not sure if Palmquist runs a 102 or 302, but it slides.

I guess if it is that little of a power band just don't slide it much. I am sure Mike S. will get him straight.

May not matter now. Rumor is we may have to postpone Newport due to flooding conditions. I cannot believe this year for weather. We will soon find out what is happening.

We think maybe a gasket is leaking and washing down the top cylinder with a small amount of water. Doing a tear down to check for leaks. Hope we find out if I need to hurry or not.

The pipe is now back to where it should be, against the header flange and the motor has been raised.

[bh/]

.. 7200RPM and a speed of 61 tops ... the boat is to glued to the water. I ran the prop even with the bottom of the boat and kicked in 3/16

"if in doubt, kick it out"
-and get some air under it....

61@7200 would give u near 70 @8000rpm
Pull the pipe in, kick it out, and jack it up,
one at a time, and if it gets on plane, it will go faster

[pro350hydro]

Really???

Lee's design is not made to slide. Period! The header is too short to slide it like a pro motor. I don't want this to become a pissing match, but who cares about national titles and who's sliding their pipes, they are using different designs. Heck J Michael Kelly and Bob Wartinger both hold C-Mod records with Lee's design without sliding the pipe so what gives? Who's theory is right? Both are right, just depends on the design.

I built a 102 pipe setup which has 2 pipes and they both slide, but it is a totally different design than Lee's.

Right now we are just trying to make it run correctly. It's easily 15mph off the pace, sliding the pipe is not going to give him 15 mph. There is another problem.
