Mike Finnegan’s new 21 Daytona!!

[cyclone]

Hey my boat made the video, thanks Mike

and it look just as good as ever!

 

[BigRedBryan]

Badass video, thanks for sharing, wish I could of made the event.

 

[Duramax]

Great video! I need some work on my trailer and that place looks amazing! I am going to give him a call since I am just down the road.

Where on the river was this? Was this Needles?

Looks like Big River. Just south of Parker.

 

[AZLineman]

Cool vid. I really want to start checking out the big River area

 

[Shlbyntro]

i like how at the end, the fam is divying up the toys for themselves, did you get to keep any of them??

Right there beside you!

 

[white tortilla]

South of Parker is all rock bars and there no water till 4pm. Only one public launch ramp that is disrepair. Just my .02.

 

[cyclone]

did some maintenance on the boat today and discovered a few things; had a blown silicone hose coupler resulting in a massive boost leak during the first water test and during our river trip. Also, turned on the boost controller and with 10 psi on the waste gates it ran 103 mph today. turned it up to 15 psi and it went 110 mph. The boat leaves hard. zero cavitation during the holeshot. It pulls hard, has one small hop around 70 mph and then it drives right past that and keeps pulling until I lifted at 110. Tomorrow we'll drop the shoe and feed the pump more water, turn the boost up again and let her eat.

TOPLESS made the video also. Your boat is beautiful but the word that came to mind when I looked at it is "complicated". It is very impressive though.

its definitely complicated. the complexity is something I've always disliked on turbo setups and there's so many small things that can go wrong. My roots are in Big Block Chevy's with big shots of nitrous. But I like learning about new things and this one has taught me a lot. Plus, its really good on gas if you can keep your foot off the floor. lol

I think I get one. not Sure which one, though. lol

 

[TexasJet]

Thankfully, you have the knowledge, resources and contacts to make something like that work. Simplicity is the key for most of us. In the four weekends I've been is Arizona my little carburetor 496 has not missed a beat in 300 boating miles.

 

[TrollerDave]

They’ll leave you whatever is broke and not running.

How does the boat feel at 110? Mine is planted and solid.

Great build! I am for sure going to hook up with your trailer place, that dude had some skills.

It's the easiest driving boat I've wheeled yet. I dont really have to steer it and it pulls really hard. I like it a lot.

I enjoy watching him build stuff.

Beautiful Daytona turned out sick!!

with three people in the boat It didn't stop. with just me in the boat it drove right through it. boat is very sensitive. lol

here's a little update on both boats. The twin-turbo 711ci Hemi-powered Placecraft jet boat is back on the water and my wife's 21ft Eliminator Daytona went faster than it has before. was a good couple of days of water testing.

Did the rerouting of the water lines help? What did it get the pressure too. What kind of regulator did you try to run first and what issues did you get




Also congrats on 111 mph. Fucking impressive

In the video, he rerouted them 3 different ways -

1. Pump to engine to intercooler, managed to push 80 psi water pressure.

2. Pump to intercooler to engine. Still was running engine a little warm. Regulator was installed too.

3. Pump to engine and overboard.
With a second line from pump to intercooler and overboard.
Better intercooler temps as well as engine temps. I think the regulator for the engine cooling side only.
-16 overboard out of the intercooler.

The water pressure on both the engine and intercooler is OK now. However, the intercooler doesn't work very well. I'm seeing 116F air inlet temp at the beginning of a pass and 172F at the end of the pass, which is preventing me from turning the boost up any more. Its current making 19 psi boost. I've spoken to the intake manifold manufacturer and they've allegedly tested the intercoolers to 100 psi water pressure in the core. They are recommending I restrict the water outlet from the intercooler from a -16 line down to a -12 and run the boat again. They believe slowing the water down will help. I'm questioning the location of the water inlet and outlet fittings on the intercooler; I believe the entire core of the intercooler is not being covered in water. There are a few other LS brick-style intercoolers out there and at least one of them is having this same issue. I've spoken to the owner/driver of a boat that has the same problem I have. I'm going to run another test an restrict the water outlet on my intercooler and if that doesn't solve the issue then I'm going to look at redesigning the water inlet and outlet of my deal. if that doesn't work then I'm going to look at a larger intercooler.

Have you considered doing meth injection on it? I run it on my 6-71 setup from aem.

Ive considered switching to E85 but since I have port injection the benefit of cooling the air through latent heat vaporization isn't as good as it would be if I was injecting it before the throttle body. Before I go redesigning the fuel system I'm going to keep on trying to make this intercooler (or another one) work properly.

Slowing the water down may help. Years ago my friends dad was having cooling issues with a muscle car. Said the coolant was flowing to fast for all of it to cool in the radiator. Your case may be flowing to fast to grab any heat. Something like only the center of the radiator had flow. Said think of it like a river. When its flowing too fast, the center flows more than the shoreline. Heat needs to dissipate or be grabbed from the shoreline as well. The middle of the river isn't enough area. You want all the water to flow evenly so you get an even cool. Slow down the flow of the river. Anyways they switched water pumps to a slower flow and it helped.

add a center section to the intake and put another cooler core in. plumb the cold water into the lower one and then through the upper and out.

come on guys, obviously he needs to try a different prop

do you have an air temp sensor BEFORE the intercooler?

before making any changes, I would want to know the turbo outlet temps by placing a temp sensor post turbo and your IAT sensor after the intercooler. that's the only way to really gauge intercooler effectiveness. also keep in mind you are starting with 110' ambient temps and relatively warm water temps.

sure 172 after the intercooler is high but if you are seeing 250+ before it......your intercooler isn't the problem........ and at 19psi I would bet you are in the 250+ range.

It's the easiest driving boat I've wheeled yet. I dont really have to steer it and it pulls really hard. I like it a lot.

I have been 130 in a 21 Daytona, and 115 to 120 frequently with 2-4 people in the boat. It was a great riding hull and felt solid at any speed. This one had a shorty outdrive and not a jet, so not exactly the same thing. Just talking about the hull at speed.

Love the build. Came out killer.

Probably the best bet to see how well or not the intercooler is truly working would be to measure the inlet and outlet water temp. Do you have any kind of thermal performance chart from the manufacturer for the intercooler? This is hydronic cooling and is in my wheel house. Happy to lend some input or info if you'd like.

 

[HST4ME]

Put a suitable size ball valve on the outlet and monitor your IAT accordingly.

 

[Nordie]

Watching the videos, my first thought was e85, there was also a thought on where exactly that you're taking the temps from. I do like what @DaveH has to say as well.

 

[DaveH]

i'll say it louder this time.....what kind of temps do you think come out of the turbine at 19psi?

I've seen 220F at 15psi in 75' air. he is starting well into the 100's. ill bet he is WELL over 250F, closer to 275 in which case he is seeing about a 100 drop.....meaning the only way he is going to get lower temps is to put a LOT bigger intercooler on it or find a more efficient turbo that isn't making so much heat. this isn't a water problem.

 

[Blackmagic94]

Also made consider making ram air tubes that would suck air away from the header/manifold might help as well.

May not be an issue but it could be possible that you have gotten debris stuck in your intercooler. I would do a back flush of your system and see if any contaminants come out.



Also I would recommend running a strainer before it hits anything of the engine for this reason.

 

[cyclone]

I'm gonna go test again on Wednesday. The only changes I"m making are install a temp sensor into the charge pipe before the throttle body. I'll be able to see temps post-turbo and post-intercooler. Also built a new 4.0" OD charge tube that will be less-restrictive than the previous version. The first go-round I didnt have any tubing to build it properly so I merged both 2.5" OD outlets from the turbos into a 2.5" OD tube that then tapered up to 4.0" at the throttlebody. The new setup should flow better. Maybe it will be less restrictive and lower IAT as well? who knows? I'm gonna try it regardless.

 

[Shlbyntro]

I love your life. once I "finish" something, I rarely have time to go back and tweak on it.

for instance, it took me 3 months to put a new head unit in the Ultra after it decided it was a submarine

most things I rarely go back and improve but I have a rare window of free time right now and so I'm gonna see if I can make this thing run better.

 

[cyclone]

I learned a lot during the most recent water test of the 21 Daytona. Built a larger diameter charge tube from the turbos to the throttle body and it lowered the air inlet temp almost 40 degrees and added 300 rpm and 6 mph to the top end of the boat. it also builds boost faster, accelerates hard and I'm ready to turn the boost up again.
