Morning Dave,
Been "REAL" busy over the winter months. Got the boat completely torn apart getting ready for a complete rewire job and new Coosa Board transom here within the next few weeks.

Been putting allot of time in my new foot pedal design and testing,now into the manufacturing mode, it hasn't been a smooth ride to say the least. Some of the work I've wanted to out source, but no body wants to talk to me about the work because I don't have 1000's of parts, I'm just a little guy and like Rodney Dangerfield said...........I DON"T GET NO RESPECT..............

Hope'n you guy's up north get an early spring to make up for the nasty winter we've had.....take care ...

hopefully it is starting to warm up by you guys in the frigid north! i'm hoping to get my boat out on sunday and do some last minute tuning before river ranch. i just figured out why my port tank wouldn't feed the slosh tank any fuel, the inside of the fuel hose collapsed! i put all new hose in this boat 4 years ago, now i'm replacing all of it again w/ the a1 style black inboard fuel line, which carries a 125 psi rating.

ETHANOL!!! I hate that crap. I`ve replaced many hoses that were collapsed on the inside just like yours. Luckily we have a station that still orders non-ethanol premium and thats where i get gas for my boat, lawn mower, edger ext.

see lots of bad hoses and have to try and rebuild way more carbs than before. Some just can't be done, usually the ones with the non removable seats for the needles.

got it back out on the water yesterday. i pretty much went thru everything while i had the intake apart, last time out i noticed the egt guages on both sides were intermittently going zero and up while running. pulled the skirt and found a tear in the rubber exhaust relief hose, replaced it. well now the egt probes are probably bad, which sux. on the 3 litre i have to pull the powerhead to change the probes. i found yesterday that the engine gained some midrange torque(accelerates thru the hop even faster), but on top wasn't getting the rpm. started doing piston/plug readings and found the engine was going rich. i wound up taking 8% fuel out of it above 6k rpm, and got most of the rpm back, and it still appears rich, it sux not having the egt working now, it worked at the beginning of the run though, and was showing 1050 at wot. i also had to change the cylinder corrections once i started leaning it out, 5 and 6 wanted more fuel, so i guess the intake is flowing more air to the lower cylinders with the increase in plenum volume. it was blowing 20 -30 here yesterday rite up the river, so top speed runs were out of the question, i just left the jackplate down to load the engine to figure out what to do with the tuning, was still seeing 100 mph at times even though i wasn't trying.

Charlie,
Are you back to running the horn intake again?

[mrcrsr]

Charlie,
Are you back to running the horn intake again?

yes, i got the mad efi intake to idle well and run good, but the fuel consumption went thru the roof, even the mid range. i think because it is so large there is just no velocity thru it, and efficiency is lost. top end would probably be great with it, but with the fuel burn rate being as high as it is would kill my range

How many different front horn designs are there?
Your first photo you say its a 260 but I've not seen that style on a 260 the ones I have seen seem to have more volume?

you have to remember i cut that one down, cut up an opti plenum, and welded the 2 together to get the correct bolt pattern. this intake was weird though, the butterfly is alot bigger in it then a regular 260(i'd have to get some measurements to id it)

Anyone make rifle drilled head bolts or studs for the 3 litre? I'd like to start doing cylinder to cylinder egt readings

[PanRonnie]

why not build them yourself?

just have to build the adapter from BSP straight to your headstud thread!
and drill the hole offcourse but you might wanna get that done by a machinist
this is how i am going to do it

btw the CAN EGT from diyautotune has 8 channels egt channels and 8 analog 0-5 volt outputs (god that,s complicated )

I currently use 1/8 npt to 1/8 compression fittings, I would have to get some head studs rifle drilled then and adapt to the compression fittings. I guess there is nothing available off the shelf
