Diesel PU Engines in a Top Gun?
 

What about a set of Duramax's in a Top Gun? It is about 350lbs more each motor I was told. With the electronics you can really get the torque and power. Wouldn't sound as cool but you might not also have to rob a bank for a long weekend.

Re: Diesel PU Engines in a Top Gun?
 

Diesel where we live has been up to 15 cents more than supreme!!! :eek: :eek: :rolleyes:

Re: Diesel PU Engines in a Top Gun?
 

the cummins 5.9 would make an even better choice, and they already make marine ones..... merc uses them... just buy one and twin turbo it..... 1600hp 1600 ftlbs torque.... but only 3k rpm and they are even closer and could possibly be made lighter than a BB

Re: Diesel PU Engines in a Top Gun?
 

they are coming out with 900/1100/1400 marine duramax's as we type this...

Re: Diesel PU Engines in a Top Gun?
 

what if I stop typing? :D

Re: Diesel PU Engines in a Top Gun?
 

What would be the advantage of diesel marine engines? Reliability? I know diesel isn't much cheaper than gas where i live.

Re: Diesel PU Engines in a Top Gun?
 

If you are looking to hop up some big D's, call Kieth over at CK. One of the Johnson and Johnson kids had one that they cranked up the Yanmars on it on Lake Charlavoix. They seem to do a good job.

Re: Diesel PU Engines in a Top Gun?
 

it will be cheaper than race gas at the upper HP levels...and remember you can run offroad fuel which is much cheaper than gas... plus they are talking long warranties... then all the benefits of turbo diesel engines..... big torque and easy idle...

Re: Diesel PU Engines in a Top Gun?
 

these will come straight from GM with warranty (as in hundreds or thousands of hours)

Re: Diesel PU Engines in a Top Gun?
 

did you? :drink:

Re: Diesel PU Engines in a Top Gun?
 

Yanmars are nice motors from what I've seen. Can they bump the HP up on them? What type of HP do you get?

Re: Diesel PU Engines in a Top Gun?
 

I don`t think that bravos are going to like all that torque.

Re: Diesel PU Engines in a Top Gun?
 

How about #6's??? :cool:

Re: Diesel PU Engines in a Top Gun?
 

how about shaft drives.... :cool: :cool: :D

Re: Diesel PU Engines in a Top Gun?
 

konrads will take it no problem.

Re: Diesel PU Engines in a Top Gun?
 

Don't think about offroad fuel in a Duramax unless you have access to a bottomless source of replacement fuel injectors or a MUCH improved fuel filtration system. The Bosch systems have no tolerance for dirty fuel.

Re: Diesel PU Engines in a Top Gun?
 

Yanmar already makes 550's in a reasonable size/weight package. There was a story a while back in one of the mags where one of Yanmar's largest repower dealers in South Florida put a pair of 550's in a 36' Spectre. Had to run like a 1.11 gear in the outdrives and a 36" wheel due to the low RPM but they did get 108mph out of it. I know the outdrives wouldn't stand up to that incredible torque for long but 6's or Konrad's would do the trick. And, as was stated before, as long as you keep the fuel/water separator clean, buy fuel from a reputable station and keep the oil changed, the oil burners will last a LONG, LONG time.

Re: Diesel PU Engines in a Top Gun?
 

the marine ones have a totally different fuel system.... inculding a complex fuel de-aerating system to get all the air out... it will be impressive when it debuts...

Re: Diesel PU Engines in a Top Gun?
 

the boat they are going into already has shaft drives.... remember we are talking about 1400 HP froma diesel so torque will be in the 2k range.... :eek: :eek:

Re: Diesel PU Engines in a Top Gun?
 

CCPerformance-
Dirty fuel is a problem for all diesels- Died fuel no problem.
That is and old BS story the dealers like to propagate. The died fuel is actually made at the local distributor with an additive very similar to ATF which truckers have been adding for 30 years. Simply a little more detergent. I have 12 Duramax trucks that have ran their entire ives with died fuel- some dealers gig the customer on warrenty claims by asking about if they have used died fuels- then they charge for flush, etc. I have hundreds of farmer friends- I am a contractor We have all fought the BS battle and have won easily.

Re: Diesel PU Engines in a Top Gun?
 

better fuel economy as they spin half the rpm of gs engines

Re: Diesel PU Engines in a Top Gun?
 

You'd lose top end, but get a better cruise.
And reduce your chance of explosions drastically, much safer.
Better range too.
Check these out.

Re: Diesel PU Engines in a Top Gun?
 

you won't lose top end with 3 speed gearboxes... ;)

Re: Diesel PU Engines in a Top Gun?
 

Sean, you got any spypics of this rig?

Re: Diesel PU Engines in a Top Gun?
 

Thank you. Don`t mind if I do. :D

Re: Diesel PU Engines in a Top Gun?
 

i do but i would have to kill you if i showed you... :D :evilb:

Re: Diesel PU Engines in a Top Gun?
 

Can you put a shift kit in the drives for that extra roost when going up thru the gears? :D

Re: Diesel PU Engines in a Top Gun?
 

It would take 6's or Arneson's to be able to achieve the diameter/pitch of prop with that kind of torque at 3k rpms.

Re: Diesel PU Engines in a Top Gun?
 

The article you are thinking about, Croozin2, was in Powerboat in '04 or '03. It was not South Florida, though. It was St Petersburg and the shop was Mastry Engine Center, the distributor for Yanmar Diesel Engines. The person in charge of the project was Adib Mastry. He put two 440HP Yanmars in a 36 Spectre and achieved 108mph in front of Bravos. What he said the problem was, is the props get too big and don't work properly. He then decided to rig the boat with Arnesons. With the surface drives its likely they will use two speed transmissions from ZF, since Mastry is a ZF distributor.

I wouldn't worry about top end. But, then again, I don't care about the top end. I just want to cruise with MINIMAL MAINTENANCE!

Re: Diesel PU Engines in a Top Gun?
 

Stormrider, sorry to say but this Marinediesels are just crap.
Its buildt from some spare-engines (AMC-Hummer).
I know it cuz some raceguys in Sweden had major problem with their setup. 10 minutes and then broke down. Now the go with Volvo D6-350 and the great DPR-drive.

Re: Diesel PU Engines in a Top Gun?
 

Big Boss:

I understand the dealer game, and obviously that dirty fuel would be a problem. I'm a DURAMAX owner and a dealer for pretty much every Diesel performance product out there including modules, programemrs, intakes and exh systems.

The DURAMAX has had injector issues since 2001. This is why they have extended the warranty and released a REVISED fuel filter for the application. My personal experience is that ALL of my injectores have been warrantied and I have numerous customers that have reported injector failures from standard fuel use. Most recently a customer that used RED fuel. His failure was almost immediate. Perhaps its a coincidence, but the point I was making is that the Bosch system and injectore are perhaps a little more delicate than most.

Re: Diesel PU Engines in a Top Gun?
 

this ain't no article buddy.... :D :cool: :drink: its not a spectre and these aren't yanmars... :D

Re: Diesel PU Engines in a Top Gun?
 

CCPerformance-- Again I concur. I only have two Duramaxs that have not had the injectors replaced ( both less than 6 months old) It was not the red dyes fault. It was GMC's fault and yes they were all fixed under the extended warranty. It is not the red fuel. You are in the performance business- I am just some jerk out here in cyberspace. Go to the nearest distrbutor and ask them how they dye their fuel you will see what I mean.

Re: Diesel PU Engines in a Top Gun?
 

Sorry Sean! I had the person confused. My fault. Croozin2 was who I ment to address.

I've been aware of the Duramax testing since the Duramax came out in 2001. In 2002, the horsepower numbers, in a marine application, were near 600.

Re: Diesel PU Engines in a Top Gun?
 

I would have to agree with big-boss. I have been running dyed fuel for years without any problems. In the farm truck, an '85 Chevy 1/2 ton 4x4 with a 6.2, I have always put an ounce or two of Automatic Tranny Fluid in at every fill-up. The ATF lubes the injection pump. I can't run offroad here in Illinois ;) that would be illegal.

On a different note, my friend Jon's '01 Duramax spit parts at 90,000 Miles and Chevrolet paid for the whole thing. He was only without a truck for 2 days. The truck did not have an easy life. He pulled a 20 Ft enclosed trailer everywhere he went and usually at 90 to 95 mph.

Re: Diesel PU Engines in a Top Gun?
 

Hey Big Boss:

I'm all about saving money on diesel fuel. I don't know much about the offroad fuel or red fuel if they are the same. The only information I've heard was that it wasn't as refined as the stuff one would get at the average gas station. What is the current cost? If it's that much cheaper, how much of the cost reduction is due to reduced taxes VS processing?

And again, I see littel problem with mech FI systems, but if there are any increased impurities, I'd forsee problems with the Bosch systems. Additionally, I'm not sure about GM warranty, but if they don't warranty for this fuel this could cause add'l problems when its time to get things fixed. I know for a fact most technicians test fuel when they see fuel related problems. This could be an expensive process.

Thanks

Re: Diesel PU Engines in a Top Gun?
 

same fuel from the same tanks...

it's dyed for home delivery/farm so you can pay the huge fines if caught running it on the road and "ripping off" the gov't for the road taxes...

think of the tint as a "tracer"

that dye stays in the truck fuel system alot longer than you think...
and you can be denied warranty for it which is...

...f'kin rediculous
it's the same fuel you buy on the street, just with some HARMLESS red tint added. Often right as they are filling the tank truck at the distributor

Re: Diesel PU Engines in a Top Gun?
 

Whats the current cost for the red fuel vs the other where you're at?

Re: Diesel PU Engines in a Top Gun?
 

right now in the "panic" it's 50 cents a gallon cheaper than undyed, taxed road fuel.

historically, sometimes more...sometimes less...

I only drive 6-8K a year anymore (8 miles to work, 20 miles to water) so it's not worth the hassle to me.

Yea, I know...why a diesel? Resale, and all the power I want when I need it. :cool:

plus I just love the scent of diesel in the morning! :D

I've heard stories of "the man" (SP, DOT) pulling into stockyards, auctionhouse lots out west and testing the fuel in your diesel pickup on the spot!

Re: Diesel PU Engines in a Top Gun?
 

They are starting to do that in CA, (checking PU's) $500.00 fine in CA. for using the dyed fuel. Right now the fuel is only about 32 cents cheaper-hardly worth the hassel.
