Re: Dry ground setup?

Typically a 383 of a generic high performance auto specification would make its peak HP in the 5400 rpm range and max torque around 4600 rpm. My friends with very high quality small blocks like to run them set at 5200 to 5500 for ride boat use. They play around with gear ratios from 2.37 to 2.68 mos...

Re: Dry ground setup?

Have you tried pitching the prop to allow you to get 5300 rpm on the trailer?

My experience was those blades liked to spin a little faster.

Re: New KelTec P50

KelTec has metallurgy issues.

Kelgren is a excellent engineer his company just can’t get the alloy and hardening process perfected.

It appears the P50 is designed around the FN magazine used to feed the P90 PDW. The patent must have expired. It’s a really cool magazine design.

PitBoss when you report the boat will not slide for you is this occurring in deep water? Have you tried running it in water less than 8 inches deep and what were your observations ?

Re: Levitator 6.2 LSA help

Start with the cap and replace it with a high quality part such as STANT brand with the same pressure rating. Make sure you are not watering down the coolant as water boils at a lower temp and mixing types (orange - green) will cause other issues. The LS engines also are sensitive to air in the syst...

Re: 500 Cadillac Crankshaft

I found Bryce some new cast 472 flat tops that would yield 8.25:1 with 120cc chambers but they were not cheap selling for $475 plus shipping from Courtney Hines.

Deano you have a source for flat top 472 pistons at a lower cost ?

When ever I find 472 pistons they are dished for the 76cc heads.

Re: Exhaust Manifold

The 1 1/2 should meet your need for a 383 spinning 5400-5600 rpm. In a natural aspirated engine a narrow long tube will aid in building torque as the scavenged exhaust gasses develop a flow and help to enhance your usable power. The use of an oversized or wider short tube will aid in making extreme ...

Re: Figuring out Gearbox ratios is giving me a constant headache, need help

Table 3 with Sensenich suggests optimum blade rpm between 2,000 - 2,400 Going by your data you sort of fall between a 2.37 - 2.55 in my opinion. That power would really be a better fit for the JX series of blade. As OneBFC told you 3 blades are not gonna get the job done if your data is accurate. He...

Big boat for a small block If it ran decent with your prior set up then this will be a solid gain in performance. A 2.55 ratio may work well with that prop too. I have run a 4 blade(82) JX and it pushed very well. You will find it sort of gives a snappy push when it spools up as compared to a steady...
