My 26 Daytona went 78.8 on GPS with a 496 HO and a 28 lab. My Raylar 600 will be done in two weeks and is supposed to make a little over 600 HP with the headers and the fuel system upgrade. I have no idea what to expect as far as top speed goes, does anyone know of any 26 Daytona running 575's ? If so, what are they runnig for top speed ?
Thanks

Don't know about top speed, but you better install more "oh shit" handles!

I would say high 80's, and maybe touch 90 with no weight in the boat.

Please tell me I'm going to see more than 10 MPH increase for the amount of money I just spent ! If that's the truth then this was a huge waste.
I would think that an additional 200 hp would net me more than 10 mph, or am I nieve ?
Looks like I may be buying a Pro Charger after all, which sucks.

Probably around 85-88mph.

I say that you should be able to break 90 MPH in the Winter....
and high 80's in the Summer.......
Also, depends where the drive sits.....
Good luck....

From 425 to 600 HP. You should be able to handle a 30 or 32 labbed prop. The key is what RPM's you will be turning the prop.
At 5000 RPM with a 26 pitch you should be running about 74. Same 5000 RPM with a 30 pitch you would be running about 85. With a 32 pitch prop 91. You see the additional HP alows you to swing a bigger prop. If Raylar raises your RPM even by 200 and you have enough HP to swing a 32 you go to 95. 400 more RPM you get 98.
Raylar can plug the numbers in for you. If you know what the RPM and prop pitch is then its easy to estimate your top speed.

Thanks FullUp,
At the 78.8 I was turning 5100 rpm. With the forged internals I think Raylar said that Whipple can raise my limit to 5700 rpm's, I was planning on starting with a 32 lab that I can borrow from a friend and work down.

Just expect to spend more money! I had a Raylar "600", let's just say it dynoed nowhere near 600hp. It only took about 30-60 seconds to get hole.
Good luck with it, I hope you don't have the same experience I did. All said and donem installing the Raylar kit cost me about 40k.
Good luck.

rvrhlic,
are you still running the Raylar package ? I hope to hell it makes the HP they said it would or I'm going to be pissed. I'm closing in on the same dollars that you did and I'm not happy about it.
I can tell you this, if I had it to do over again I wouldn't. Every time I turn around I'm buying more "stuff" for it and spending more money trying to get things to fit. I wish the fuel system upgrade, comp reprogramming, oil cooler upgrade and all the other crap was advertised and included in the kit price. If you read Raylars info it souds like for 6K you bolt on some parts and POW you got 600HP. Not the case at all.
Anyone planning on doing one of these 600 kits, plan on spending some serious dough.

I got rid of the Raylar engine. I had one that was built be them and probably would have not made it through the next season (according to a couple of different mechanics). But yeah they said I wouldn't get the HP with out this and that and when they installed what they recommended it LOST hp on the dyno. I have to say, Ray is a good talker. I ended up selling the piece of #%@ and getting a real engine.
Man, if you are closing in on what I spent, I feel for you. I ended up giving up on the Raylar engine after abour 6 months of them trying to get it right.
and by the way, before I got rid of it, it took longer to plane and went about 5mph faster than a stock 496HO.

I say you'll break 90 once, when everything is right. Other wise you will run in the 80's. I have to ask? How can you guys spend 40K on a 600hp kit? When you can go to GT Performance and buy a fuel injected 650hp motor out right for that same money or really less then that.

Andy Agreed..40k on a worked over 496 for maybe 200hp??

I got 20+ mph out of twin Raylar 600's on a fairly heavy V bottom, so you should easily be into the 90's in a daytona cat, with the caveot of needing to have your ECM reprogrammed by Whipple for the higher rev limiter of 5,500.

26_Daytona
05-17-2006, 06:08 PM
It's easy to spend that kind of money when you factor in the machine work to make a 8.1 ready for this type of upgrade. Factor in pistons, crank, heads, rods, all new stainless metric bolts, roller rocker, new roller lifters, 1,000 dollar Titan oil pump, headers, oil cooler,14 qt oil pan, fuel system, comp reprogramming, reassembly etc....it adds up in a hurry.

If you do in fact have 600+ HP you should be able to run 90 mph, 1 person in boat low on gas. If you have a labbrd prop, 28 pitch will be 5700+ rpm, 30 pitch will be 5300.
I have run 92 (summer time) at about 5700 rpm, lab 28, 27 Daytona, Teague 620 motor,Teague Platium (1.5) XR short drive. Tested with 28,30,and 32 pitch lab props and same speed with each just different rpm. I have 2 GPS speedometers on board. The 26 has a very similar bottom to the 27.
You should be able to run 85 with boat loaded with people and tanks full.
Hope this helps.

I have to tell you earlier they told you to get handles-- try a 19 Daytona Blown 572 that is get handles that big bad boy should be like on a rail. Lucky shit :rollside:

28 lab, low on gas, 5100 rpm, November in Washington runninng in the salt water. That's how I did it. And no, I don't have thru transom exhaust, mine exits my drive.

It's hard to beleive Ray is not explaining all the extra cost up front. $6K for 180 HP seems very reasonable. For $40K or less you can get a Merc 525 package that generally dynos out at 560-570 HP, 520-530 at the prop. The HP3's (496's built by GM and marinized by Innovation) put out 565 HP without the Raylar heads and they come with all the good stuff in them. I really hope the Raylar conversion does well for you and lasts. You probably have spent about the same either way. :rolleyes:

For $40,000 you could problaby get a 540 blown making 1000hp.
and run in mid 120's I think you're spending you're money at the wrong place.
for $26,000 you could buy his 700hp. package single carburetor or fuel injected you're choice or go out with a big bang twin turbo set up 565 making 1500hp 1586torque fuel injected for a mere $85,000 :cool:

No way does a 26 Daytona with 600 hp run 98 mph. As far as rpm and prop pitch, you need to know his gear ratio to figure out a projected speed. I still say high 80's maybe 90 on a good day. Look at what a 26' west coast cat runs with about 600 hp and that is about where it is at.
My 26 DCB with about 800hp ran 106. That was a blower motor putting out a lot of torque. It takes a lot of hp to run a 26' (west coast) cat to 100 mph.

Here is a link to a calculator you can use. Just plug in the variables that you know (or estimate) and you can see what you should be looking at as far as speed.

I spent 40k by foolishly giving Raylar about 13-14k and then had the new engine built. So if you are spending that for just the Raylar... that is not good. You will enjoy the extra HP and speed.
I hope you have a better experience with their engine than I did. Any by the way in no way did Raylar explain the costs up front. In fact to this day, I am positive they did not even know about the ECM reprogram until after they did mine. I was promised an engine I would love by Raylar, I ended up with: an engine I hated, a ruined boating season, another 25-30k out the door. I would never trust a word Raylar says, get it all in writing!
By the way, Daytona, who is doing your install?

05-18-2006, 01:58 PM
Had a 2001 26' Daytona with a Merc 575/XR w/ 1.5 gears turning a labbed 32. Summer, 3/4 tanks, 2 people it would run 85 tops. I then installed the Arizona Speed and Marine 575 kit (120 thermostat, smaller blower pulley, reflash the ecu, MSD box), they claim 80 horse. Who knows? Never got to 90.................89.8 GPS as the best.
600 horsepower is all you need as long as it's coming from X's!!!!

I'm sorry to hear about your experience with Raylar, mine has been good up to this point. We will have to see what the engine runs like once it's installed.

Daytona, keep looking forward with confidence knowing that you are benefitting from the experiences of those of us that helped work through the developmental process for the 600 over the last year. Because I was one of the "early-adopters" of this new technology (and anticipated learning bugs), I lived through the learning curve on the need for and programming of the "e-box" and upgrading the fuel system to keep up with the additional horsepower. Now I'm on to the next phase of potentially upgrading the computer program itself with a higher rev limit. I'm starting my second season of strong and reliable engine performance, and am looking forward to even more fun this year. The past is in the past. Enjoy being in the "here and now".
