Yes please on the component info. What was the cost?

I talked to Brian today (my man @ Havasu) and he told me my entire steering system is now Hardin Marine. Remember this setup was done over 2 years a bit at a time. I know now no half assed hybrids will work. You need full hydraulic from helm to the leg.

Today I saw an all time best of 91 mph. Conditions were glass water and the temp was about 105F. This would be a 1 to 1 1/2 mph increase over any previous speed. My rpms were about 5200-5300 as a result of my propman giving me a bit more cup. I expect more speed as the temperature drops.
Not sure on the limiter, it kicks in at 5400 on my tach, which may be out 100 or 200. i was so impressed with my steering today that "I TOOK MY HANDS OFF THE WHEEL AT 90 MPH"
my wife just shook her head! No problems! Now I need more power!

Terry, be careful of the rev limiter. It removes fuel to do the limiting. It can easily damage the engine when running a supercharger.

Also, the 496/Whipple motor we built last year made peak HP at 5500 RPM. It had the Raylar blower cam in it and a 5700 rev limit. You probably should get them to raise your rev limiter if you've got all the forged internals.

Good advice. Thanks. I will look into this.

I know this is kinda a dead thread, but Desert Rage (Jon) tried my Merc labbed (it does matter who labs) 32 @ Mohave last weekend. He's running about the same 600 hp power & got his best 89 @ 5500. Good place to start, seems quick to me!

After some great test results it really does matter who labs your props :drink:
He ran my pseudo lab 30 the same day and got 86 @ almost 5500; WHAT??? :crazy:
Obviously there is a difference and my 30s are headed to BBlades for the Merc profile :drink:

Jon's hp is actually ~675...

Merc is good. They tell you very accurate what to expect if you give them accurate prop slip data. They can even adjust bow/transom lift if you know what your looking for. Turn around was only about a week too.

He's getting about the same #'s as me down there. Maybe my Whipple 500 isn't making the claimed ~750 hp or my GPS is off or altitude doesn't make much difference for SC motors. My best was 87 before rebuild @ Mead. (Same trip I blew a head gasket) Ran 87 all the way back to the trailer maybe with a rich water/fuel mix? I'll try to get a good run next spring @ the Desert Storm. I'm hopin for 92ish.

Why do I obsess over a couple mph?
