I want to point out only myself and a few others have decided that. Many still think it’s the only obvious choice. And to be fair, the LS won 4400, 4500 and 4800 at KOH, so there’s that.

Someone did mention that it is a scavenge pump...Not a pressure pump. Maybe someone does know how much oil gets pumped thru a motor at say 50psi pressure. I have never played on the oil side of SBC engines...other than pans, pickups, and "high volume" pumps vs stock or high pressure.
Lately, thru Eric, we have put numbers to power rack steering. A TT pump can flow as much as 55 gallons/minute and up to 1650psi, and consume as much as 35hp. Those are high end numbers but I made brackets and belts to withstand 35hp of torque. Eric does mention that 35 gallons per minute UNDER USE is about normal but think what is going on in the PS reservoir to flow and ditch air i that small thing. A dry sump reservoir is REALLY big and a packaging nightmare. More than the pump. MAny of the guys run covers for the belts. But a tough learning experience to get them right.
Rocks in and under the car are rarely mentioned, but every team has a strategy for them. With each fail, more deflectors are added. jason's problem was a rock stray rock exploding the servo/orbital. That has happened to others over the years. When doing media video you had to be respective to of rocks thrown and advise the newbies who just thought about the cars.
Good information on the pumps. I do know that it took less than 1 minute to take all the oil out of a 460 ford (7 quarts) when the oil filter gasket blew out. A data point.....

Yeah and that's the same story every year, fast people breaking.
No it's not
200hp is stock
Most people say Chainey and the hunter (Miller) brothers are in the 500hp range.
You're also on crack thinking those guys are 1800 lbs, again that's stock wieght. With all the reinforcement, spares, tools, nav, ect. I'd be surprised if they were much under, if at all, 3k lbs.
Seriously if you can't draw the parallels yourself and wanna get stuck in the mer..actuchly it's then this thread is turned into mental mastrubation at best.
id lump in the same boat as slawson, miller, and byler. they will are not going beat everyone but they have a shot at winning

I bet there are several motors that can run all day long at 10k RPM on a dyno. But look at that motor after it hits a wall and instantly stops. Usually junk. How many times a day might that happen to your 4400 LS. What makes a LS or Ford Motorsports motor north of $30k to survive that? Rumor has it that Joe Gibbs motors are used in Baja TT where there is more consistent running,but generally un-popular in Ultra4. Recently you will hear the Dugan Name, who seems to have found a robust offering. Most seem to use Motec ECU where most sensors are redundant. Only if both fail will the engine shut down.
From some of the banter on here. It seems that if you are not or cannot build for a serious car that could get you in the top 10. Then you should be saving and modify up a SXS. Not seeing a healthy co-dog get out of the seat at a bottleneck to help clear it.... Says 90% what the team might be about...and not about this thread. . I was glad to not see 150 cars in 4400. And 44 completed the course, which might be the most. (100ish start)

I didn't know that. I just figured they were main bearing priority because that's how basically every engine since the 1960s has been designed.
Probably yet another reason so many teams are running those Windsor based engines and frenchy is being so snooty about oiling solutions.

His entire fleet is mains priority oiling.

I think marine applications is where it's at. That's probably the engines with the roughest life out there.
All Chevy's are top end priority oiling. Since the beginning. Ford Cleveland and plenty of other V8s too. If anything, this thread has been amazing at showing how much you don't know about motorsports and Ultra4 in general.I didn't know that. I just figured they were main bearing priority because that's how basically every engine since the 1960s has been designed.

Show me those "so many" teams running OEM Windsor engines, short of JR4X.
Anyone with an aftermarket block has priority mains, LS included.
Would it be idea to start limiting pre running days in rocks or just make no pre running zones. you can go walk on it but not drive in them.
how many thousand passes goes trough those new hard rock trails and just level them out before main race.

I think that you would be leveling the competition with the lowest denominator.
If you want to put the effort into pre-running to find an advantage, I think that you should be able to.
there is no pre running in rock crawling. dont know if bouncers can

Yes, bouncers can walk the course.there is no pre running in rock crawling. dont know if bouncers can
And this is Ultra4, pretty different deal, it's endurance.
I wish the course didn’t get obliterated by the night wheelers as we are pre running and preparing to race on it. Chocolate Thunder got screwed up Wednesday night before the SXS’s had to run it. A trail car knocked a huge boulder down into the only line I could drive my 35” tired rig on. I smashed my driver door in on the pivot rock for a line that wouldn’t be there on race day.
But that’s probably part of the excitement for the crowd. You guys watch us flounder on shit you know we pre ran. Get to talk shit about how we can’t drive (you’re not wrong). And we’re out winching with a drone buzzing around our heads wondering wtf happened because we know we drove it no problem a few days ago.

Engine problems solved
Novelty itemLS 4cyl? I doubt they’ll ever make the block but it could be cool. But a cast iron block makes the whole package 300 lbs.
I thought it was cool at first until I started thinking about it
Most modern 4 cyl DOHC heads will outperform an LS head. Not to mention said modern 4 cyl is aluminum and probably at least 100 lb lighter than that 4 cyl LS.
May be good for some sort of class restricted engine but there are better 4 cylinder options out there
I wouldn’t count it out completely but it’s not the end all be all.
There’s some benefit to having simplicity when compared to a DOHC. SBC pattern out of the gate meaning no adapters to run common transmissions.

I think it is still no pre run for king of motos and course not open till day of the race, they do not even know where they are going to start, or used to be that way. maybe do not release course till day before. Let the driver figure it out on the fly not on a beat in path. I still think the guys should be driving down the rock trails rather than all the bypasses around them.

It’s exactly half and half. We go up 50% down 50%. And they rotate it year to year. It’s called course flowI fixed it for you
course didnt spend anytime on lakebeds, so there was no high speed drag racing

I have it setup very similar, however rather that pulling ignition, I have it pull 10 degrees of timing. That way I don't have it shut down on me on a steep hill climb where it could turn bad, but enough to know that something is wrong

Casey Currie nearly won this year, and his Trophy Jeep is big. Tom Wayes was announcing and commenting on how the rocks are gonna slow him down because he’s so big. It didn't seem to happen. I don't think the size/weight of the vehicle is as important as y'all are thinking it is. Then again, that may have been why he took out a diff, if only he had an axle sponsor.
