3 and 4 valve pushrod engines.

[Vatarr]

Are we going to be able to make 3 and 4 valve pushrod engines in this game?

[Killrob]

No, the current valvetrain options are the final ones for Automation 1.0

Here's some history i've found about that subject. Looks the guys over at GM's defunct Oldsmobile division were playing with that idea for a while brfore them bean counters decided to pull the plug on that project altogether.

I was thinking more like a diesel engine. (Like a 2000 5.9L Cummins turbo diesel I6 with 4 valves OHV)

I think the newer vetts also use a 3 or 4 valve pushrod engine IIRC.

No they don't

The duramax diesel engines for consumer trucks use a 4 valve OHV engine layout and produces 445BHP and 910lb-ft of torque.

I remember seeing video of the BMW M1 with a Nascar engine in it so I tried to make the same thing but I can't get the OHV 5.8L engine to 10,000rpms and 800-900BHP. So I doubt that the game is modeling these things well enough to make anything outside of OHC engine layouts worth while.

The game simulates pushrod engines just fine. Don't try to compair a highly developed and specialized race car engine to a production one. Automation is a production car tycoon game, not a race car simulator.

I was talking about production vehicles like a lot of diesels. Pushrods in this game have a disadvantage because they aren't allowed to have 4 valves like the OHC. Pushrod has many advantages over OHC but in this game they're just the cheap bargain brand valve train.

OHV engines do not need to have 3 and 4 valve heads in order to make power and toqrue as LS motors as pushing 10,000 rpms making 1,100 to 1,200BHP normally aspirated. For drag racing setups they push those engines to over as high as 12,000rpms, I remember that this game use to have OHV and then modern OHV options however at some point they took those options away.

No it really doesn't, also they allow you to use racing type fuel as well as racing compression ratios and race headers so no this game does allow the building of some such engines.

Outside of Diesels, almost all pushrod production engines are 2 valve (one intake one exhaust), and diesels will not be in the base game, but rather a possibility for DLC later. The devs have made this clear in the FAQs.

Those engines built for NASCAR are literally the most purpose-built RACE engines you could get, using components the "racing" production engines would never use due to high cost and high maintenance (for the average buyer). Yes a top fuel dragster can hit well over 1K hp and spin well over 8K rpm, but it's also built to live a single quarter mile at a time, not to live for 100k miles of regular driving (and let's not forget how expensive it is).

Secondly, production "race" engines would include any high-performance varient of such engines for sport and track trims of cars as well as for super and hyper cars, and as such take more time irl and in Automation to produce, so it's not like it was simply thrown in to make uber race engines.

Third. List 10 common pushrod engines that can rev over 8,000rpm and are mass produced for automobiles.
Just try... While the LS series has shown that enough research can push pushrod engines (lol puns) into the modern era, it also proves that PRODUCTION PUSHROD engines have their limitations, just as illistrated in the game.

Speaking of which: Automation simulates hydraulic lifters, not solid lifters. Obviously hydraulic lifters are widely used in production engines due to the minimal maintenance on the end user's side. Don't go thinking that just because some special engine made in the 60s can rev over 6000rpm that Automation is wrong. That engine in the 60s was a high performance varient that had solid lifters (and thus every 3,000 miles needed to have the lifters adjusted).

Cpt. Doc, If you wish to continue pushing the "Just because a 5.8L nascar engine can do 10,000 rpm, automation is wrong" line... Then you should probably unplug from the internet for a few days and do some old school research at your local library.
