sounds like some big gains to me, but I would excpect to trade a little reliability for performance, Sounds like pretty good ratios to me

I cant see that, but who knows, my old 25 was good to see its best of 68.7 gps with a 502 mag w/ ecu upgrade, CMI's, and K&N running a 23" mirage plus at 5,000

Thanks, Liquid asset. That ties pretty much up with where my 25 is (2miles slower) without the CMI´s. As the K&N doesn´t do anything for the performance (same goes for removing turbolators on 496´s) it must be the ECU and CMI advantage. Definitely worth having but at around 4-5000 $ that almost makes a Raylar 103 seem like really good value.
As this is really a Raylar thread - I will add that what concerns me is that I am pulling 525 hp out of a block that is maybe not going to last running flat out at all the poker runs next year. If I buy a HP525, I get to sell the healthy 496 that I take out, and the mercury product is, by all accounts, going to survive fast WOT recreational usage easy! Oh yeah, and there is something blue under my motor hatch.............

@ 272 owners - I am in contact with the swedish 496 owner - hope to answer your questions soon
Best regards

What would happen with Raylar kits on twin 496 ho's in a 28 Daytona cat that currently runs 90 mph?

They were bought in march or april of 05. I tighten them by feel to around 15 foot lbs. I have used different versions of locking rocker nuts on at least 50 different motors Ive built and other than this motor I have only had a nut crack once in the past (It was a cheap imported looking harland- sharp). I ended up switching all the rocker nuts to arp's and haven't had any more breakage in 30 hours of run time,Smitty

Articfriends:
Our rocker lock down nuts are are own special AFN design whcih is a net zero adjustment type like the factory stock units, nothing like conventional polylocks. We had a small quanity show up without the champfer at the bottom of the threads and when some of these were over torqued past the 120 inch pounds or 10 ft/lbs specified, there were a small quantity that split and loosen. We have recalled and replaced these nuts to prevent the overtightening crack possibility.
