A friend of mine asked me to post this on his behalf:
Cylinder deactivation: Used on a number of Chevrolet and Chrysler’s V8s, this technology deactivates cylinder banks during light engine loads as perhaps you’re already aware of. It’s a great way for naturally aspirated engines to remain competitive compared to turbo engines in the economy department, especially pushrod NA engines like the Chevrolet and Chrysler V8s known for the tech which in the game, can’t even use VVL.
Advanced gearbox: Unlike with individual quality sliders for bottom end parts, I can understand why some would find detailed gearbox sliders too complex and micromanage-y. I mean, I personally kinda feel that way about suspension in-game, but you added the presets to please both crowds. Therefore, I propose two like-minded solutions for gear boxes. The first is to keep it the way it is currently for casuals, but add an advanced button which when pressed, reveals a new tab with the sliders for proper gear ratios for each gear including one for final drive like in racing sims.
If for some reason that’s not possible, then a probably less pleasing for casuals, but definitely possible way would be to do exactly what you did for suspension. In other words, have the advanced options right there on the main tab, but have presets for the casuals like maybe “short”, “medium”, “long”, “economy short”, “economy medium” and “economy long” (the economy ones having a the last gear be super long just meant for highway cruising) and have them use the final drive slider the same way they do the current top speed slider.
MOHV made available from 1955: I hope you’re already aware of my usual complaints here so I don’t have to repeat them, but as much as those complaints still are and always have been true, MOHV has always had the potential to be a great and much needed addition to the game. That being if it was available from the mid 50’s to replicate the high performance American pushrod engines of the mid 50’s to early 70’s, and given my experience, it seems to me that MOHV as it is currently might be offering just the right amount of performance necessary for those engines. I think you guys said MOHV has basically identical performance to DOHC 2 valve, so I guess I could even put it to the test in video form and link the results here if you’d like. Sure it probably wouldn’t be as simple as moving the date it becomes available back, you may have to tweak things here and there, but these are things you should’ve done before you even added MOHV.
For seriously even some of the earliest small blocks require max 15 quality and are still a little short, meanwhile I’ve always found modern ones possible and this is all easily provable, I can link to examples of it being true in older builds and make a video showing it’s still true now. And if you guys think MOHV was necessary to replicate modern LS engines, then there’s absolutely no way you guys can honestly say it isn’t necessary to add a valvetrain to replicate those classic muscle car engines. And since it’s related, please add VVT for regular pushrod again… you most likely removed it as a failed attempt to make MOHV well, less completely unnecessary, it didn’t work.
Minor engine designer changes: The first is something that’s always kinda bothered me about the game, the fuel efficiency of the engine being called “Economy”, I think it should be changed to “Efficiency” or “Fuel EFF” as it’s meant to be the thermodynamic efficiency of the engine or something right?
Single and Multi-point Injection I think should be changed to the names I’m more use to and think are more common, Throttle-body and Port or Sequential Injection, I think it would fit better too. Mechanical Injection, Throttle-body Injection, Port Injection and Direct Injection. Also, add multiple throttle bodies for Single-point/Throttle-body Injection? Such configurations existed such as Chevrolet’s Crossfire Injection. Apparently American car makers used the same intake manifolds for it as their carburettors, so you could do the same with the new intake designs your incorporating in the revamp.
Less minor, but still, I think single barrel eco carbs are both OP and the opposite of that. 3 of them together outshine a 4 barrel efficiency wise and aren’t much more expensive if I remember correctly, I don’t think that should be the case. And what are they meant to represent anyway? My first thought was like how American economy engines (or at least cheap family ones) often had 1 barrels, but they’re way too restrictive for that, I think carbs might need to be recalculated at some point IDK.
