Has anyone tried one of these....

http://www.holley.com/HiOctn/ProdLine/Products/Marine/FMS/FMSFI/700-21.html <br /><br />A Holley Marine TBI digital fuel injection conversion. Posters on a Ford Winsdor engine forum, that I frequent, swear by the automovive version. Better HP, better cold starting, smoother idle, better economy.<br /><br />It ain't cheap, but I'm giving serious thought to scrapping my new (used) holley 4bbl and adding one of these to my new 331 stroker.<br /><br />Any experience out there?

Re: Has anyone tried one of these....

Interesting, a computerised and non-computerised version.<br /><br />I would also give it consideration but I couldn't find a price. For me, that would be the decider.<br />How much was the computerised version?<br /><br />Aldo

Re: Has anyone tried one of these....

It's a little less than twice the price of a new 4160 Holley Marine 4bbl carb. It's $799.00 USD. I'm not sure what you saw re "non computerized". The link is for a Digital system. Holley originally made an analog system, I don't think they sell it any longer.<br /><br />The Ford Windsor gurus claim 20-25 hp and 25-40 ft lbs of torque plus all the other attributes listed above.<br /><br />edit: correct price is $839.00 at Summit Automotive. The marine version is a little more expensive than the auto version.

Re: Has anyone tried one of these....

Down the bottom of the page there is two links for non-computerised versions - they accept adjustment from a laptop. (maybe I read it wrong, I'll take another look).<br /><br />Thats about $1200 in my language, close to beening viable concidering fuel savings and increase HP. Thanks for the link.<br /><br />Aldo<br /><br />Edit: Reread the link, I'm an idiot, I'll go stand in the corner now.

Re: Has anyone tried one of these....

Dunaruna, here is the link where they talk about the Holley system. I've been with this forum about the same length of time as iboats. It's the place I got steered onto doing a 331 stroker (from 302) instead of going to a 351W. Some of these guys (fred, bcmcdaniel, wayne, bob, ralphD, sixtyfourfairlane) really know their stuff. Some of them are real professionals at the art of motors. There is quite a bit of traffic from Australia and the UK as well. Wouldn't have thought you Commonwealth guys would have been into V-8's, but they're crankin out the horsepower just like the Yanks.<br /><br />Look at post #20. That # will increase as new responses are posted. Holley TBI has been mentioned before, as well.<br /><br /> http://www.network54.com/Forum/119417?it=0

Re: Has anyone tried one of these....

Thanks again for the new link. Very interesting, I've never heard of an after market (bolt on) injection system. <br /><br />I run a 302w in my boat and yes, v8's are very popular down under, always have been. We might not go for the big SUV's but we want the grunt. One of the most popular upmarket locally made cars is a 5.7 L twin turbo or supercharged, they can't get enough.<br /><br />Back to boats, I would have thought that raw water contamination of the oxy sensor would be a problem in a boat, how do they overcome this? I have the log style manifolds, the raw water exits through fittings toward the rear of the manifolds. I think my system is called a half fresh water system - not sure, I'm still learning.<br /><br />Aldo

Re: Has anyone tried one of these....

This might be one difference between a marine and an auto system. I kind of think the marine version does not use an oxygen sensor. One is not pictured or described. Autos have to have them for emission control. Boats, here, in the US are not regulated. But there has to be some way that the system reads mixture. <br /><br />I am going to email Holley for some setup and operation details.

Re: Has anyone tried one of these....

The 700-21 is an open system, no oxy sensor. The 700-51 & 52 are closed systems but they don't mention marine use. The closed system might only be viable for boats that don't have the raw water exiting through the exhaust (is there such a thing). <br /><br />The ECU can't make fuel delivery adjustments without the oxy sensor yet most modern inboards are fuel injected. Interesting to learn what holley has to say.<br /><br />Aldo

Re: Has anyone tried one of these....

I just fired off an email to Holley on the subject. I won't wake you up with the response. I will post the results tommorrow night about this same time. I asked for general setup/tuning information and noted that there would be no possibility of using an oxygen sensor, for fuel delivery adjustments, or an emissions sniffer or a dyno with motor in boat. I'm sure they have the right answers.

Hi Boomyal,<br /><br />I could kiss you..... I have been suffering with a problem with the carb on my engine for almost 10 years now. I considered and priced up injection about 5 years ago and found it to be too expensive. This new Holley kit is the answer to my prayers. I can finally p*** that carb off. I'll be giving it a burial at sea, with the words "Good riddance!"<br /><br />Vancouver has my vote.....<br /><br />Chris............

Re: Has anyone tried one of these....

Achris60 Have you done a float test on that carb. It works everytime? You find a large body of water it has to be 100' or greater because you can dive. You hold the carb over the water and drop it. If it floats its good if it sinks its bad. This test has never failed me yet with an old Holley carb. If you need any more infor You can email me at The MarineDr.com Oh ya he's from Canada

To all interested, send me your email and I will forward you a pdf file, from Holley, re Marine Pro-jection 2D installation and operation manual.<br /><br />lockan@yahoo.com

I dunno Achris60. I've never been kissed by a Koala or a Kangaroo before. <br /><br />Actually, that's not true. As a young lad, back in '70, I bought a Triumph Bonneville (mail order) in London, went over picked it up, toured England for four weeks, hopped a ferry to Norway and met an Australian bloke, my age, on the boat. We got along great, so I offered him a ride and we toured Norway, Sweden, Denmark, and parts of Germany together before we had to go our seperate ways. I wish we had kept in touch. We had a great time.

Boomyal,<br /><br />Thanks for the e-mail. Very informative.<br /><br />Aldo

Vinney,<br /><br />Usually find the float test works well on spark plugs too....<br /><br />Chris...........

Re: Has anyone tried one of these....

For all interested, the use of an oxygen sensor does not negate the need to go thru the tuning proceedure for setting up the system. It does however provide for more flexibility and accuracy in it's operation. Once you dial in the various operation parameters as outlined in the manual, the oxygen sensor will continuously fine tune, at all levels, up to 15% from your set points.
