Who are these guys winning super late races with junk ? I'm not talking once a year when it hasn't rained in 2 months but winning on s regular basis in a super late running junk ... I'm waiting for a list

Technically speaking, I would bet the wet sumps are harder on oil than a dry sump.   Especially in the lower classes.   Dry sumps have more capacity, more filtration, better flow, and an oil cooler into the mix.   Locally on a 1/4 mile, their isn't much difference in RPMS between a wetsump street stock and a dry sump late model, other than one has a $100 oil pump, and the other a $1,000 oil pump. One is towing a 3000-3300 lb car around, and the other a 2200lb car. one depends on the factory oil passages to direct oil, and the other puts oil exactly where it needs it most,   One runs a coffee can size oil filter, and the other a coffee cup.  One with a reservoir and cooler and the other a 7 qt pan.    Heat and dirt is an oils worst enemy, not sustained high rpms.

Well heat is not much of an issue with full synthetic oil. It doesn't break down like conventional and its viscosity stays consistent. So less sludge and maintained oil pressure. But on the other side of that, if you change it often enough then the oil doesn't have time to break down. I have heard mixed feelings between the two though. Not sure how many are running conventional these days but im sure the engine builder has his recommendations.

So you are telling me your turning you cadet 84-8500 ???

even with 9qts in a wet sump motor you will run in the pan dry if you are turning over 7800rpm constant. I cant see anyone turning over that. In fact I bet most of them dont cross the 7000 mark.

Not to mention the valve train would explode without titanium valves and shaft rockers which I don't think are allowed

I know I'll be laughed at for saying this.  But John Brady #96 late model runs Marion Center, Hummingbird, Dog Hollow, and used to race AMP builds his own engines out of his own garage.  I'm not saying anything about his driving abilities, but among other things John is known for being able to build one hell of a motor.  Multiple drivers have driven his equipment and all say the same thing.  "If he ever gets the handling figured out we're screwed!"  He broke his wrist a few years back and put Jim Parsons in his car.  first night out Jim won the feature at hummingbird.  John was consistently top 2 or 3 at AMP running against the likes of Luke Hoffner and Duane Stiner with one win to his credit.  All with a motor that he built in his garage for about $10k.  In fact, get a hold of him he's selling everything trailer, race ready car and whatever else he has for $15k

Dude just stop .... Anyone can build and explosive light switch that can't be driven ... Professional builders build smooth , powerful , reliable pieces. Your trying to argue that some guy in his garage has more indepth knowledge than guys who build national title winning pieces and you sound like a clown doing so

[ramsey31]

While not sustained, I was close.  7800-7900.  Tight 1/4 mile.    While I can "backyard" build an engine, I would much rather pay for the expertise to get "smooth, powerful, and reliable"  IMO it was $ well spent.
