Re: 2020 Supra B58 Engine Teardown - First Look - Better than the 2JZ?

Is this a true performance engine? My opinion is that it's not. Everything is done for cost, emissions and economy over performance. Then there are no "true performance engines". Emissions is always a concern when designing an engine for the road. If you can make the engine inherently clean, you ca...

Re: Engine oil temps

For passenger cars, normal operating temp is anything below 250 or 260* F. It's not considered overheating until that point.

Re: Laminar Flow

I didn't click it yet but if that's the "Smarter Every Day" channel, he has a few videos on laminar flow, I think, and a bunch of other really interesting stuff. Laminar flow is his favorite thing in the entire world lol. He talks about it a lot. There's one vid where he shoots colored vortex rings ...

Re: SBC 283 forged pistons

You'll likely end up needing to contact Autotec/Racetec for custom pistons.

Re: Valvoline VR1 for flat tappet cam break in?

I prefer to use a good break in oil with the ZDDP additive mixed into the oil. A good oil with a separate ZDDP additive is my second choice. I suggest pre-oil the engine to circulate the additive and oil before firing it up the first time. It may take a bit for the additive in the pan to get to whe...

Re: Dart Little M top end oiling? SBC

Ironically I was just reading a thread about this exact thing yesterday. There may be some usable info in it. They give specs on maximum groove size and there are pics, as well.

Re: Hemi vs Chevy wager...

Anybody that pay $24k for 650hp has more money than brains. That's just ridiculous. I guess he paid that so he can say it has a hemi? My money is on the Chevy. It started out as a lot less money... he bought the complete iron head 426 with single 4 bbl for under $12K add dual quad setup add new sol...

Re: Tech Speakers at the Race Engine Challenge

Not sure I'd call them that. It's not the 'new' EMC. Yea, it's another engine building competition but just because it's still going and the other one ended doesn't make this 'the new EMC'. Same goes for AETC. Just because one ends doesn't make the remaining conference 'the new AETC'. Yea, it's a co...

Re: Plenum box with two inlets and one outlet

Whatever happened with this? Did you guys end up using the box? How did it work? Anything done after that as far as modifying the box or making an entirely new one based on results gathered from this one? The box worked, but we relocated the MAF (and went to dual MAFs) so now there's a y-pipe there...

I fully understand the procedure used to split it even before I posted this, I was just very surprised that cracking at the same time 2 of the most meaty sections of the rod took only 1500 lbs of applied force!
Sorry! :oops: For me, that wasn't clear in the original post.

Re: Rod strength

If it only takes 1500 psi to crack these Rods in there thickest section, then how strong can these production Rods be? Its a 'pre-scored line'. They didn't just crack a solid chunk of metal, with 1500 psi in a targeted manner. There was already a failure point built into the rod so it would crack t...
