Raylar Results
 

Just got my dyno sheet.

BCK 103 conversion on a 496 MagHO.

So far , it's everything Ray said it would be. Huge increase in torque at midrange. 527 hp at the rev limiter. :evilb:

Next is the water test.

Thanks Ray ! :D

Re: Raylar Results
 

Impressive!
Can you post the dyno sheet?

Re: Raylar Results
 

Rmbuilder has the dyno sheet. He is going to write an article for a magazine about the project.

It would be up to him if he wanted to release the dyno sheet now.

But I can tell you this......at least on the dyno so far.....it works !

Re: Raylar Results
 

David:

Thank you for your good words. I always makes us feel great when customers get excited about the results of our kits. I got my copy of the dyno sheet and the numbers are again impressive as we have seen from two other independant dyno evaluations. The torque is probably the most incredible item. When torque from about 2000rpms up to over 5000 rpms averages more than 550 ft./lbs and stays over 550 all the way to 5000rpms., the boat is going to run, torque does the work and a torque band like this is just like a diesel, nice and flat except its still flat a 5150rpms!! Wiat til that "toy" hits the water! That will be equally impressive. We just finished the dyno runs on two of our new HO600 496 cu/in. Mercury motors we built for a customers new 32 footer. They made 607HP at 5100rpms at the revlimiter and 640ft/lbs of torque at 4200 rpms with torque again staying over 630 ft./lbs all the way to 5100rpms!!The printout shows the horsepower still climbing at 5100 so I am sure at lets say 5400 rpms this motor will probably be over 625HP based on the still climbing line of the power at 5100rpms. This was also done on the stock Mercury ECM!! with our new piggyback programmer. A Michigander on these boards will have his HO600 closer to dial in this weekend and we expect pretty awesome results based on our preliminary testing earlier this month a Lake Havasu. I don't want to steal any of his thunder, cause I know he will be really excited to post his results when we get his boat dialed in. You probably know the boat it was in the shop with yours. In any event congratulations on your results I will be waiting to hear your in the water results! Should be great!!

We'll keep massaging the 496 and see where we can get!

Cheers!

Re: Raylar Results
 

The thing I am pretty interested in ( besides kick butt performance) is that there is the true potential that this will make my boat more fuel efficient in the cruising mode.

My hunch from the beginning is that getting just on plane with a very efficient hull will happen at lower engine RPM once my 496 was Raylared.

And thereby, quieter.

And draining 87 or 89 Octane.

We have pre - conversion numbers.

However, it is not going to be a pure comparison because I have added a standoff box with hydraulics, and planes. It was for control , of course , as I have learned from many OSO posts.

More to follow.

Re: Raylar Results
 

any thing in the works for the 525efi?

Re: Raylar Results
 

Has anyone tried the Raylar system with a Procharger? Would the intake make a difference under boost? I would love to see how your intake works on my rebuilt 496 with M1 Procharger 8 lbs boost.

Re: Raylar Results
 

great numbers! Ray, that torque sounds pretty impressive!!!

We should be finally splashing our newly ralyar'd 496 HO this weekend ( Baja H2X, 24', 3900lb dry weight) and doing some prop tests. Ran a best of 73 on GPS in stock form so we are hoping the Raylar boys can help us to 80mph.

Re: Raylar Results
 

Ray:
I like the fact that you have taken a clean slate approach to the 496 and have achieved results that no one has done to date. I think you guys deserve a lot of praise as the "pioneers" of the 496 aftermarket.
Have you guys given any thought to doing a set of heads and manifold of the same design that will bolt to the Mark IV, Gen V and VI blocks? It just seems that the tall symmetrical port design really works better than a traditional BBC siamesed port design and I can only imagine the power potential is there for even larger 500++ cid motors.
I guess I'm thinking of a happy middle ground between a set of stock style rectangular port heads and the much larger Dart "Big Chief" symmetrical heads.
Obviously, the cam would have to be changed as well.

Re: Raylar Results
 

:drink:
Great job Ray!!
What exhaust was this motor dyno'd with?
Thanks,
Dave

Re: Raylar Results
 

It was dynoed with stock Merc exhaust.

No engine mods, besides the Raylar BCK 103 kit.

Am adding a more efficient oil cooler kit before the engine goes back in the boat. Moves the cooler to the back of the engine, includes a cleaner look , new braided lines, a bit of bling.

Re: Raylar Results
 

Senecadds..what cooler did you go with? I just picked up one from "franky" over on hotboat.com. Should be showing up at my door in the next 30minutes according to the boys in brown (UPS)

Re: Raylar Results
 

Matt,

Yes, I am installing the "Franky" Oil Cooler Kit.

His real name is Frank Doerfler, and was great to deal with.

Re: Raylar Results
 

its a fairly pricey kit but it looks like its up to the task. All the fittings and braided lines should help sprucen up the generator...i mean 496

Re: Raylar Results
 

Matt99: what were your water-test results with the Raylar kit this past week-end?

Re: Raylar Results
 

Ray,
Does that mean you have all the mapping and everything dailed in for the 600 hp? Alos what exhuast did you have on the engines that were dynoed? I have not had a chance to get out on the boat since you sent the computer back to Aaron, we will be getting up a week from tomorrow, I am hoping everything runs smoothly.

Re: Raylar Results
 

Modern Marine's other Raylar upgrade with the 106 kit hit the water over the July 4th holiday in a Velocity VR1. This is the Michigander Ray referenced earlier. Last year the boat could barely hit the rev limiter with a labbed 26" Bravo, 1 person in the boat, a half tank of gas, and the tabs and trim up for speed. This year five adults with all their gear and a cooler, plus a full tank of gas, running a 28" labbed Bravo quickly ran into the rev limiter with throttle and trim left to go. That's also with Gibson bullet transom mount mufflers.

This kit required using Raylar's "ebox" connected to the stock computer, and replacing the stock fuel pump/filter system with an Aeromotive pump and 1/2" fuel lines into and out of the fuel/water separator. The engine also uses the 14 quart Dooley oil pan and Hardin oil cooler/thermostat. The engine looks as great as it runs! It's like you hit nitrous once you get above 3500 rpm. It's amazing to be zipping along at 4500 rpm and hit the throttle and have instant acceleration left. Getting rid of the stock rev limiter will be another great improvement.

Re: Raylar Results
 

David, if you haven't seen your engine painted yet, the color is the same as the pictures I attached. The upholstery and air inlet tubes look orange in the pictures because the sun washed them out - they are actually bright red. However, the color of the engine's intake manifold and valve covers are very close to the actual color. I saw your dyno sheet and you've got a great performer. The dyno used has a reputation for being tough but fair.

Re: Raylar Results
 

Thanks Escape Velocity !!

Being so far away, I had no idea what the engine would look like. That red powdercoat looks great.

Are those the Basset(sp?) headers?

I plan to add a set ,not sure which, but wanted to have a more pure comparison by using Merc standard exhaust.

Anyway, congratulations on your project.

Now I am really getting excited to see my boat ! Hope Jeff finishes soon.

Dave

Re: Raylar Results
 

Dave,

Yes, those are the Bassett tri-Y headers. I posted on the thread about the CMI exhaust with some information about them. They look really great, and they're all set up for both the 496's exhaust water temperature sender and the stock "tee valve" for the cooling hoses.

I'm off for the weekend to see the "Smoke on the Water" poker run and a triathon on Sunday. I'll be looking for Jeff and his boats at the poker run.

Randy

Re: Raylar Results
 

Randy,

Good luck in your tri Sunday. I gave up on tri's last year and just cycle. Bad swimmer. :( Got a few medals , but too painful. Sloppy stroke, but I can pedal.

Heading over to So. France to do the last week of the Tour with Trek next Friday.

The CMI's might be a good idea, but I haven't found very much information. This is very new , right?

Dave

Re: Raylar Results
 

I really have to say that Randy (owner)and Jeff of Modern Marine our Michigan dealer really did an awesome job of building and rigging the "Red Monsta" HO600 496(previous 425hp 496HO) in Randy's "sic" "Escape Velocity!" Its so rewarding to know that all of the design and development that Larry and I have sweated over the last three years is continuing to bring the best compliment a high performance development company like us can have, "A Big Grin on the Owners face!"What Randy now has is an honest 600HP EFI 496 cubic inch motor with awesome torque and the reliability of our forged internals. It has the system secrets and efficiency of our kit parts that produce a motor that will idle at 650 rpms, make power and rev well beyond the 5150 rev-limit of the stock Merc ECM and still provide all the wonderful reliability and safe engine control thats provided by the wonderful Mercury "Guardian system" Our new stainless coil relocation brackets, the Jeff's awesome powdercoating and the polished 316 stainless Bassett/Raylar "Tri-Y" headers complete the bling and keep the "Monsta" breathing! Those of you with 496's can now see that your motors can be upgraded to horsepower levels from 525HP to 600HP+ and still run your stock HO ecm and use all of Mercury's great accessories found on the stock 496. The best part of this is that it can be done without supercharging and the big dent in the wallet that has accompanied some aftermarket and "blue" motor offerings. We are hard at work on all kinds of new 496 "goodies" including our 572 cubic inch 700HP+ EFI 496 motor and our new electronic IR efi manifold that will make "Bling Bling" and power like you've never seen!! As I've said before here on OSO, stay tuned more's on the way from Raylar!!
Again to Randy and his "Escape Velocity," Congratulations on a project "Well Done!! Wait till Randy" rev-limiter is reset to 5600 or so rpms!! The Grin will get bigger!!!

Ray & Larry @ Raylar

Re: Raylar Results
 

Ray,

You're right about the big GRIN! The new power has transformed the boat's performance. There are many great things about this new motor to love, but I'd like to re-emphasize two points. First, the idle at 650 rpm, though sounding awesome, is incredibly docile for docking and dealing with the long no-wake areas I have to boat through to get to Lake Michigan. You'd swear that it was a stock motor. Second, the tolerance for 87 & 89 octane gas. I could never consider supercharging because my boat spends much of its summer on the hoist, and I must buy whatever gas is available at the marinas where I boat.

I have peace of mind with the reliability of the engine and drive by having your H beam rods, Mahle forged pistons and roller rocker arms, combined with the upgrade to my Bravo X drive with Max Machine Worx gears, bearings, top cap and prop shaft.

Finally, I truly appreciated the collaboration we enjoyed as we worked through the final implementation of this project. Your accessability and the "adult supervision" you provided was a big source of help and confidence. Any future enhancements to the programming of the computer will be frosting on the cake.
Randy

Re: Raylar Results
 

Will you Email me copies of dyno sheets for the 496HO with stock ecm and exhaust manifolds for....
1.) Raylar heads only with your 1:1.8 roller rockers and optimized fuel pressure but stock injectors?
2.) Raylar heads and cam only with your 1:1.8 roller rockers and optimized fuel pressure but stock injectors?

Re: Raylar Results
 

why with all the talk of power why do I see no post of Dyno sheets. what is the big deal of showing the measurements???

Re: Raylar Results
 

PM me your address and I will send you all the independant dyno sheets you will need.

Ray @ Raylar

Re: Raylar Results
 

are we getting any where with the 525 efi Ray?
