Hi, I’ve got a few questions concerning carburators, pushrod engines, the quality setting and valve sizes.
Will we be able to select the airflow on a certain carb configuration?
For example, the standard engine is going to have a 650CFM 4bbl, while the more powerful engine is going to have a 750CFM one.
I think the power limit on 4bbl carbs is also very low, and the octane ratings should also be a bit lower.
I hope the answer won’t be ‘Just increase the quality’.
2: Pushrod engines
I have a feeling that pushrod engines are very underpowered in this game, losing power extremely quickly.
I don’t think the dropoff is so extreme in real life.
For example, building a Chevy 454 that revs to 7000rpm without losing more than 50hp of peak power (at Year 2014), is impossible unless I crank up the top end quality setting to 10 which makes it expensive to build.
We should be able to select lifter type and individual part quality, and it shouldn’t mostly affect man hours.
3: Quality settings
Why does changing the quality setting mostly increase man hours?
Doesn’t it also imply using higher quality materials, eg. titanium or magnesium instead of aluminum?
Independent quality settings for different parts under the same category should also be implemented, especially in the bottom end where it’s usually the pistons and rods limiting the redline.
- Valve sizing
Will we ever be able to change the valve sizes to achieve a effect similar to cam profile settings? (Also, is ‘manual’ lift/timing control possible)
EDIT: Three more things.
- Fuel type confusion
In RON mode, 91RON definitely wouldn’t be Regular.
95 is ‘Regular’ almost everywhere.
91 should be low-quality (in 2014).
In AKI mode, there should be 87, 89 and 91 (Regular/Plus/Premium) settings, which are common in the US, instead of the huge gap between 86.4 and 90.3.
- Fuel injection
You’ve already stated that you made Single and multi point EFI when most manufacturers started using them, but I think that’s not true.
I think most manufacturers started using EFI, both single and multi point, EFI in the early 80s, definitely not late 80s/early 90s.
For example, the 3rd gen Camaro with its TBI and TPI injection systems.
It makes developing realistic engines a LOT harder.
They spool waaaay too late, almost no boost until 2500rpm unless you want the car to be limited by the turbo at 5000rpm.
