509 whipple sidemount blower set up
 

I just dropped my 509 off to get re done. This project has been a SERIOUS P I T A !!! The boat ran great Until gremlin #1 (employee) winterized it & cracked the block, bye bye gremlin #1. Bought a brand new GM marine crate 502 let gremlin #2 (new employee merc certified) put it together, did'nt use the jumper when setting timing, bye bye head gaskets, had short block gone thru bored to 509, gremlin #2 broke a ring on assy & damaged piston, bye bye gremlin#2. After working on my current project in the boating on a budget section (finally pulling the trigger) with the help & suggestions of the fine people here on OSO that project has been an absolute blast & has renewed my interest in this project. Injection setup has not been altered from when it last ran well, stock 415hp roller cam, am upgrading lifters & rocker arms & heads to handle blower. I am also upgrading oil system & cooler, would like to upgrade cooling system as well, serpentine setup, what will work? or leave it alone? I am also changing exhaust from emi thunder to cmi because I sold the emi & found some straight tailpipes for the cmi's I already have. Question here is the whipple system has a exhaust probe that was tapped into the emi manifold, where & how do I mount it on the cmi's. I was thinking the easiest thing to do would be to install exhaust spacers & just tap in there, yes/no or have a bung installed in a primary tube? Thanks in advance, Randy

dam gremlins hate them fkrs .:lolhit:

At least these gremlins were fireable too bad I could'nt make them unhireable!!

Not trying to be smart but why not change the cam while you are at it ? That will add to your hp gain in a big way. And yes you will need a bung in the exhaust to check A/F ratio's. I would also have it run and set up on a dyno by someone that knows what they are doing, this will be the best money you will spend . Just my .02

Hi Jeff P31, The main 2 reasons to stay with the stock cam, 1 when I bought this boat with this setup & all was good this thing was a guided missle! It would accelerate so fast it would make your cheeks ripple back on your face! Reason 2 the ecu is already programmed for this cam combo. When I get the boat running again Eliminator suggested adding K planes to the hull cause it starts chine walking seriously above 85mph I saw 100mph 1 time but had to back off for safety & the engine was still pulling hard. Some history on the boat, 2000 Eliminator 250 eagle not sure what deadrise but its shallow,Teague platinum bravo imco-2shorty 30p bravo1 labbed, add on dual ram hydraulic steering. I am having the base engine dynoed to make sure all the inards stay in but have'nt found a shop than can do fuel injected blower setups aruond here yet. I will keep this thread updated as I get more info. Randy

I would get rid of the piggyback Whipple ecm and go to a Mefi 4B. The piggyback will more than likely eventually fail. There are a few used ones around but you can't buy a new one. They haven't made them for over 10 years. Without the piggyback ecm, you don't need the egt probe.
There are also a few mods that should be done to the fuel rail (depending on which one you have) and the entire fuel system.
We have done tons of them. If I can help, give me a shout.
Eddie

EGT was just for warning, has nothing to do with the running. If you don't install it, the light will blink a warning. You can weld a 1/8" NPT in any of the cylinders to install it. We also have resistor that you can put inline that will just tell it normal temp so the light doesn't blink.

Thanks Dustin that info can make things easier to rig if you bypass it, my thought is that it was put there for a reason. I just talked to Youngs about the post he wrote & dang that dude is smart. I have another whipple charger that is new but has never been set up & we talked about both sets. This one is set up & ready to go but has not been used for a few years, after talking with Eddie @ Youngs it should work ok but could most likely use some updates, the new one has never been ran so will need ignition & tuned & all of that. Being that I own both of them already I have to weigh the cost between the two, The new one is for sale & someone is supposed to look at it next week if I dont get cash in hand at that time I will look harder at setting it up & selling the side mount. If that is the case I might look into a cam change as Jeff P31 suggested. My thoughts on this build is to get the boat running without going stupid in the pocket book so that is why I was going with the side mount. This build should be interesting with no gremlins but me, thats why I am putting this out there so hopefully I wont become my own worst enemy. Thanks guys for the info & suggestions I will keep things updated as I go. Randy

No shortcut just more money
 

Jeff P31, I had to learn the hard way about shortcuts I would have said vortech as I have some experience with those guys & will never do business with them again as a result. After talking with Eddie @ Youngs I am leaning towards the new whipple I have unless it sells real quick & with that as posted I might do a cam change as well but the rest of the rotating assy should be good to go. I think Dustin was just throwing that out there as an option because those blowers are pretty old & the computors are not too smart. I have talked with him a few times & he is pretty sharp.

Let there be no doubt Dustin know's his stuff ,that's why an answer like that surprized me. It looks to me as if you were saving all the good parts . I'm sure Eddie told you to go with the newer whipple and he is just the guy to get you fixed up. The man just has these engines figured out and has alway's been willing to help out .

Actually he didnt try to direct me either way, we talked about both systems & he had read this thread obviously but after listening to my situation as far as dumping money into this project he explained what it will take & why to make either package work. That is why I started this thread, there are a lot of people on here that know what they are doing & I believe can steer me in the right direction with either setup. The more I think about it the new blower is the way I am leaning but I am not going to pull the plug if this person wants it, They need to bring cash with them though because I wont play games with waiting around. It will be sold or used. Randy

Have you hugged your gremlin today?
 

:poopoo: I opened up the boat today to start cleaning and this is what I found. After removing the parts & rinsing out it's not as bad as I thought at first. The side mount will not be reinstalled in this boat, After talking with Eddie @ youngs concerning upgrades & physically seeing the components I will be selling this system for a reasonable price for what it is. I am posting some pics so you guys can see what I am working on & welcome comments, advice. I hope to make this project as fun as my "Pulling the trigger" project. No time limit & NO GREMLINS!!! LOL Randy

Best of luck with this project Randy . Sounds like it's gonna be a rocket . Shoot dem fockin gremlins !! :lolhit:

Randy, just make sure gremlin # 2 (or anyone else) has replaced the 11 psi oil bypass valve in the filter pad with a 30 psi valve since the crate motors does have the 11 psi valves factory installed.
If you have the common marine setup with filter and cooler in series differential pressure between inlet and outlet of this circuit might exceed 11 psi and you will suddenly have unfiltered hot oil going directly to the crank.

Gremlins
 

Alex, thank you for commenting. Thankfully gremlin #2 is long gone & good riddence, as far as the oiling system that entire setup will not be used. I have been looking into a drop in complete engine assy from a builder you all know. I wanted to build my own with assistance from a pro but adding up the cost of parts, machine work, dyno & tuning, & taking someone away from their job to walk me through a project they cannot put their name on for quality assurrance is not worth putting this boat back in mothballs over. I will I'm sure pay a little more up front but the result will be worth it. Anybody got any coupons? Randy

I grant you one OSO coupon good for 10% off . :party-smiley-004: This is for the gremlins...http://i1243.photobucket.com/albums/...ps7388e5ab.gif

Thank you Sam When I am done adding up everything I have planned 10% will give me some gas money to enjoy it with. LOL. With the sidecharger out of the picture I need to change the title of this thread, does anyone know if or how I can? Thanks, Randy

The sensors are mfg'd anymore and the temps will vary depending on placement on different headers, different cylinders, different heads....... You can always install a Livorsi EGT gauge so you can see the number vs a pre programmed number. We haven't used those in 10-12 years!

Thank you Dustin for the info the side mount will be for sale shortly as I just found out today the sale of my top mount setup fell through so I will be getting it back. I need to aquire some fuel system parts for the injection system so I can sell it as a complete bolt on computer to fuel pump & everthing inbetween. Randy

Randy, it sounds like you will be able to use the top mount on your new project now that it's back in your lap, which is by far the better way to go than the side mount. I have had the side mount unit for 11 years now, and I would like to do more, but it just doesn't pencil out to use the old platform & technology to convert to bigger power. Let me know what you plan to do with the 509, I may need to start a new project!

Hi 28 Eliminator, I already have another home for that engine. My Sea Ray needs a new engine to make it sellable. I will put it together stock & be able to sell it as a running & reliable boat. The Sea Ray & the side mount setup will be for sale to help with the cost of this project. If things work out I will have 2 items available for someone to use & enjoy at a price that is reasonable. I will have another 502 when I pull it out of the Sea Ray that was overheated. I will post if it is any good when I get there. Randy

It sounds like you got a lot of work ahead of you, but that is a good plan (just keep the gremlins out). I would be interested in the overheated 502 if the short block is any good, once you get that far along. It's time to start planning another motor project. Keep us updated on the new motor for the 25!

28 Eliminator, send me some pics of your boat. I cant see your avatar very well what I can see the graphics look cool. Randy

Let's try this link and see if it comes up.

Nice

Thanks Randy, I will keep my ears open for anyone looking to get a side mount whipple, although it seems like most people are buying newer boats with newer engines. I love the looks of that top mount whipple you have, and that is what a few guys around here are using on the newer setups.

Thanks 28Eliminator, I am supposed to pick up a complete FI system soon so I should have everything to bolt this system together stock and with the blower ecu & all for a reasonable price. I believe it will be easier to sell that way than just a blower & manifold. I like the windshield on your boat, wonder if the dimensions are the same. My little shield thingies start folding back at about 70mph & its like shoving an air chuck up my nose & hitting the lever LOL.

LOL air chuck! I helped a friend fix his 25' 01 eagle last year, and it is very breezy. It makes a huge difference in wind pressure and I'm glad I have the shield. I could measure his and compare with mine if you are interested in getting one. I have heard they are expensive as heck though, something like $1200-1500

I would appreciate that as I can look around. I think yours is the first eagle under 30ft that I have seen with a windshield & I like the look. As for the air chuck we could get creative to entertain ourselves or get out of working on a jet ski!!LOL

I will see if he is around this weekend and try to take some measuments. In fact he still has my rinda scanner I need to get back. When ever I ride in anyone elses Eagle I am amazed at how well that wind shield works. It is still breezy, but pushes the majority of the wind over your head. If you want the wind just sit up a little higher or sit on a throwable cusion.

The cost of the windshield may be worth it being able to save sunglasses.LOL

Just let me know if there's anything you need from us. Your top mount system is by far more valuable than the side mount. It also will fill the motor better at your elevation. Highly recommend it.

Bling & decals
 

I will Dustin, Thank you for taking an interest. I agree about the top mount being more valuable, I had already put it for sale before the bug bit me to finish this project, that is why I was going to use the side mount. I am glad the top mount is coming back because with the cost of doing this I will be showing some bling. LOL. Its not like I'm building a sleeper! I got a couple of stickers made up to let people who know the boat that the spinich has changed, What do you guys think? Apperently OSO is having tech problems, Will post decals later.

Problem solved I hope
 

I thought these were kind of cool, What do you guys think?

I'm foist to the finish cause i eats my spinage i'm Popeye the sailor man !! I thinks it's great . :lolhit:

Popeye?
 

LMFAO, Well that settles that huh?:poopoo::lolhit:

Where did you find the images at. That will definitely let the guy's know something is up.
That is one bad a$$ looking Popeye!

zedge.com they have free downloads of TONS of stuff. I'm also thinking about a decal of a 100 dollar bill for the dash just for fun. LOL Randy

I have a 99 OL 502 w/whipple side mount, still has the piggy back computer and secondary fuel pump. Everything is stock other than 8:1 pistons and MLS head gaskets. I blew a head gasket last summer, pulled engine and rebuilt her this winter. As of now the injectors aren't pulsing, wont start. Engine check light is on, whipple check light is showing code 15 (I think). I have went over grounds and all connections, everything is good to go. I am thinking of buying a Mercrusier scanner or PC software to read/delete the codes, and run an injector test. I need the tool anyways.

Will the scanner allow me to read/delete the code on the piggy back computer?
Is this the next step, or am I just missing a simple ground or a bad connection?

Or should I ditch the piggyback computer and 2 injectors pre-SC, and get my MEFI 3 re-tuned and go with bigger injectors?

Any help would be appreciated and if anyone has a pdf of the instruction booklet, that would be awesome! I bought the boat 5yrs ago, 1 owner w/160hrs on it, SC was installed @25hrs. It now has 250hrs on it, I replaced the SC 2 summers ago. The boat always ran great, GPS 74mph. I know my way around an engine, but this is the first SC and MPI I have ever rebuilt. I'm not trying to push things to the limit, just want what I had, 74 is good for me.


Thanks,
