Re: SCAT 9000 Limits

Imma put this right here.
9000 crank. Broken rods and lots of other parts too lol.
I had to cut the cap off the rod with a 5" cut off disk and the crank survived and it still in service.

Re: SCAT 9000 Limits

I've been using them in USRA/IMCA type CT engines, 550-575hp and 7200rpm. SRP Forged or KB Hyper pistons, 12-13:1cr. Dart heads or Brodix T1 heads. .5 percent overbalanced, 6" SCAT Pro Series Rods with 7/16ths bolts, 6 3/4 ATI dampers. The cranks live a good life. I crack check them at 100 nights, r...

Re: Speed Pro at2000 lifters to restrict upper end oiling?

I don’t like restricting oil. I’d rather add oil for cooling, and work on getting it back to the pan quickly without it getting in the way of the crank. The springs seem to appreciate the extra cooling and routings the oil via bigger returns in the front and back work well for me.

Re: sbc stock connecting rods

I've only seen one set fail in a CT525 worked over by Ballwin Racing Engine's in STL. They even said the power levels of the power/refresh were pushing the limit of the rods. They lasted around 100 nights in a Super Late Model before spontaneously auto-disassembling themselves.

Re: Engine Masters rod ratio test results

Every time I see/hear/read one of these shows/articles that go about testing stuff I get the critical feeling that ratings and controversy are more important and cleverly hidden inside illegitimate ABA type testing. It’s really hard to take any of them serious when something kinda important is gloss...

Re: What grit for lifter home.

320 for me. No issues that I know of yet. I use 50/50 cheap 10-30 oil an WD40 for home jobs.

Re: Tightwad at wallyworld

Lame opinion here about to happen. After reading and cussing and discussing for years and years on the nets and bench racing with buddies and some critical thinking skills on this subject says to me, if you change the oil on the regular, maintain on the regular and drive it like it was intended, any...

Re: Why does a tighter lsa need more compression?

I'm just here to complain about the word "dynamic compression" when IVC is actually a mechanical thing that CANNOT change therefor isn't dynamic at all but instead STATIC!

Climbing down now.

Carry on using the wrong terminology if you wish.

Re: Trying to salvage a 400 sb with Dish pistons.

Buying rods and cutting pistons negates the reason the OP doesn't wanna throw money at it. Assuming a 4.166 head gasket and deck height of 9.025 and a real 40cc below the deck then the math nets you at 9.5ish CR. It'll work just fine. IF you have to buy heads to get this done than I'd spend money on...

Re: Valve lift vs. port flow and cam selection

I'm pretty sure Mike Jones covers this in a previous thread and his theory is about the area under the curve. More lift, even if the port can't flow it, means the valve get too and stays at longer, the lift range that does matter the most. Sort of like the port hitting peak flow twice, once on the w...
