Raylar Stage 2 Kit
 

I’m looking at a new Raylar Stage 2 kit for my 496 HO in my 2007 26 Outlaw. I’ll have it professionally installed. What are others experience with the kit? Reliable? Top quality parts? Performance/HP as advertised?

Not sure I'd go that route. $8k in parts plus assembly and still have a cast crank in the engine?

What route then? 600HP

The best thing they made was the sheet metal intake and they stopped making them.

The nodular crank is good up to 700HP+ they dont become an issue till you do the large supercharge kit. If the cast really makes you nervous (and it shouldnt) they offer forged cranks and also stroker cranks too. The only real weak point is the cast pistons but if you do the full kit, they are replaced.

There are a bunch of us on here that have the 600 and some with the 525. IMHO, the kit is nice, But I opted to weld fittings on the fuel rail to use an aeromotive fuel regulator. I wasnt a fan of the little in-line regulator. Other than that if you have a marine shop do the short block, the 496 only goes together 1 way, you cant mess it up, its stupid proof. The only thing they can screw up is the bore and ring gaps which I think Larry will tell you what they prefer. Then, set the fuel pressure, tune the ecu and go boating.

He can still get them. The reason they became scarce was due to his provider significantly increased cost. When I got mine, it was like $1995. BUT, he can get the same flow out of a modified stock intake anyway. However, as we all know, they are ugly.

Above post is spot on.......

I have the Raylar 525 kit minus cnc heads. Very nice parts, cam ground by cam motion.
My setup is turn key reliable. I am running a Whipple Stage 2 tune with base fuel psi @ 47 vs stock 43. Monitoring AF/ R as well.
I agree with Keith, for the stage 2 kit dump the stock pump/regulator. Go 1/2 fuel lines, aero/weldon pump, regulator, return to tank. You will also need your pcm tuned. Whipple has base map tunes for the 600 to get you started.

The stock 8.1 crank is not your GM 80s cast crank. It's a nodular iron and very similar to stock LSX cranks. 600hp is ok.

His original custom welder died in a diving accident I heard. They are making them again with a new fabricator. Larry said a ported stocker with 90mm tb will flow 80% of the coolgap.

Still quite a bit of a heat sink though compared to the cool gap? So close on flow but higher IAT.

I havent spoke to Larry in a couple of years but I thought it was better than that.
