Twin Illmor Y2K
 

Rick could this be done?
Those motors are quite a bit lighter than Mercs arent they?

Re: Twin Illmor Y2K
 

i dont think so....can barely squeeze twin small blocks in....now a single Illmor and a konrad or a III drive would be da bomb...

Re: Twin Illmor Y2K
 

Not sure if they still make the 3 drive. What about a staggard boat?
I remeber a thread a while back about staggaring 525s and weight was the issue I think but Illmors are much lighter.

Re: Twin Illmor Y2K
 

I think with staggered you lose the back seat. If you want a twin Superboat then the next step up is the 34.

Re: Twin Illmor Y2K
 

Nothin Wrong With That.:cool:

Re: Twin Illmor Y2K
 

ff, i think the ilmors are like 800lbs each... about 350-450lbs lighter than a 525efi.
btw, i was discussing w/ parnell about a pair of these in a 28 saber w/ konrads... that would be a nice ride.
On the 28-30ft range, the weight would really help the balance.

but i think 7ft beam will be a tough squeeze, and a stagger in short boat would really limit the cockpit space... if you care about that. ;)

Re: Twin Illmor Y2K
 

Or twin Whippled 6.2 @475-500hp. Damn !!!
We already know the stock twin 6.2 runs 84.

Re: Twin Illmor Y2K
 

Johnny, I did go through the twin staggered ( 496, 525, ETC ) set up with JC and Rick, anything can be done, look at the turbine. The real issue becomes the new onwer absorbs all the retooling and design costs, as this would be the first one being built. A great idea, even with just 496 HO's you would perhaps see 100 mph !!!!! :D :evilb: :evilb: :evilb: ..................hmmmmm, perhaps my next Y2K !!!!!

Re: Twin Illmor Y2K
 

If they can get 750hp out of a naturally aspirated SBC for nascar, with a whipple you could get 550-600 easily and reliably. Fuel Injected of course.:D

Re: Twin Illmor Y2K
 

Guys 84 With Twinn Stock Merc Small Blocks Is Great ! 84 Mph At Probably 4800 Rpm. From What I Remember The Drives Where Very Deep. Through In A Pair Of Shorty Lowers And Some Props It Mite Pickup A Few More. Now Through In A Pair Of Whipples , Naaaa. Im Old School How About A Pair Of Zul Small Blocks Reving 7000 Rpm All Day. 5000 Rpm Is Boring Sounds Like A School Bus Up Hill. 7000 Will Be Like Being At A Nascar Race.

Re: Twin Illmor Y2K
 

agreed, the stock sbcs in the 80s w/ a 5yr warranty and low maintenence is pretty cool.
But JC perf could build those same sbcs as zul for alot less.:D

Re: Twin Illmor Y2K
 

Hell if the 555 CI motors in King Sting turn 7500rpms, getting small blocks to do it would be easy.:drink:

Re: Twin Illmor Y2K
 

WOW a nascar race in the GSB WTF!!!:eek: :eek: :eek: how cool:D ::D happy new year tripps

Re: Twin Illmor Y2K
 

I said old school. Like ARMED AND DANGEROUS - FEVER - RC MARINE - EXTRACTOR Now that was some noise. All Zul powered. I guess you could call JC Zul junior. Jeff has become quite reputable and buids some great pieces.

Re: Twin Illmor Y2K
 

You will see Fever Racing again this summer.. Those small blocks are being assembled as we speak.......

Re: Twin Illmor Y2K
 

Steve Morris builds procharged 800hp 372inch sbc's that would work well!

Detune them slightly and the bravo's will live.

1400-1600Hp twin Superboat that should run 110Mph+!

Might even be able to kick some Activator A$$!:D :D

Better hurry though! I hear Activator is going to build a #6 Boat....And that can only mean one thing!

Re: Twin Illmor Y2K
 

Where is this Steve Morris? Any contaqct info?

Re: Twin Illmor Y2K
 

Steve has one of his 1200Hp motors in a 25 Baha with a #6 drive.
Can't remember, but I think the boat ran 109 at the Loto zoo.
It was mentioned in the "single V with a #6" thread located in the general boating section.

My buddy has the same 25 with 800Hp and it only runs 86...Goes to show you what brute power can do for you.

Here is what your looking for,
http://www.stevemorrisracingengines.com/

A bunch of motor for 24 grand.

I bet JC Perf could put together something similar.

Re: Twin Illmor Y2K
 

KNOTWRIGHT your bud with the 800 what is his drive height ?? I put on a 2'' shortie and am up to 83.2gps 670hp at 5900rpms before the drive change and carb went to a nickerson 1050 I was hitting a wall at 74. and theboat flys leveler now, but it wants to chine walk over 76 so you have to drive the sh#T OUT OF IT TO KEEP IT STRAIGHT , but that will change this winter putting on the inside hdy steering only had the add on before. bblades think he can get me 2 more mph.

Re: Twin Illmor Y2K
 

AIR TIME,

Buddy runs an Imco shorty with a medium (unknown to me) spacer. Currently he has a stock Bravo prop and has been told by a few pros to change props and remove the spacer.

He has full hyd steering but his boat still gets weird in side wakes or waves. You really have to drive the boat. His current setup blows and I don't like the boat in rough water anymore.

You are right though, I think he should be running faster.

Re: Twin Illmor Y2K
 

nickersons has a 24baja to, that the son said his father can run faster than him. because you have to drive it ,they have about 1000hp said its hit 100.

Re: Twin Illmor Y2K
 

Yup,
Driver boats scare me when the water gets snotty......Probably cause I suck at driving them!

Seen to many high speed fish hooks at the Poker runs.:eek:

These are the engines for a twin engine Y2K...:evilb:
http://www.raylarengine.com/550_engine.html
Hell, 1 of these in a 24' would scream...:drink:

pat, i think the $ on those is low-mid 20s incuding header.
me likey.

Same power as the Merc 525EFI, 2/3 the weight, and 10K less $$...:cool:

raylar LSM550 is 500lbs.
merc525 is 1201? per merc page.
Ilmor is around 800lbs so the 525 has to be about 200 heavier.
Is the 1201lbs w/ drive(approx 150lbs?)

but w/ no merc warranty.
Any Raylar dealers in the NE?


.......oooooooooooooooo, look what i just found.

http://www.raylarengine.com/images/550_engine.jpg

An Iron Head 502 BBC marine engine does weigh about 1000lbs with exhaust all the accessories. The Merc 525EFI weighs a little less do to the aluminum heads and CMI headers.
My guess is that a Bravo drive, transom assembly and gimble housing add up to about 250lbs.
Yea, that all aluminum V-10 is like 150-200lbs lighter than a 502.
This new all aluminum small bock is really light!

Good questions...

And do we know what engine this is based on?
The new GM 6.0 or 7.0 small blocks found in Vettes with a stroker crank maybe?
Or a Dart, or World Products aluminum race block?
I gotto know...:drink:

I talked with Merc's Fusion boys in Miami (consumer motor referb division) and they are about to release a 383 motor that is very close to the same numbers as the Raylar motor. I do not remember the exact details, it was so new there was no price set at the time of the show.

They are taking the base 350 (I am assuming that is 5.0) boring and stroking it, doing a hand build up to what they referred to as a small block beast.

Was an interesting discussion and I got a little green man out of the deal.

I think they were blowing a little smoke T...
To get 500+HP out of a 383 (6.2L) and be marine friendly would be tough. Unless, of corse, you bolt a blower on it. Merc Racing did build the 377 Scorpian for a while and I believe that was rated 350HP at the prop.
I have seen some nice 450HP 383 cube sbc marine engines offered by some builders.

This new Raylar is a 550HP 450cube (7.4L) small block...:evilb:

and it looks the chit too. :cool:

I could not say if it is chit or not. I did ask how this "new" motor would compared to the old 377. The response was this motor was being developed to replace a big block in some applications, with the HP and torque numbers to match. They quoted numbers but I cannot remember what the heck they were. I guess we will need to see what they release over the coming months.
