What i mean´t by that was, when you unnequip a Headlight (happens on the Old Pessima and the 200BX) the filter gets more air, which would mean to me (Car Guy/ Engine Specialist) the turbo would perform better/ get cleaner air, instead of that hot air that comes from the engine (that is usually "stuck" in the engine bay) If the Devs added a kind of "Air Flow Simulation" they could also add a Headlight Funnel, to channel the air. PS. The 200Bx has a more "hidden" Filter maybe there could be an extension pipe to help use the Headlight Funnel better.
Uhm, nope. It does make a difference, and its not a 2/3bhp increase. I´m an expert on car/engine matters, and a good K&N Filter make about a 20/30bhp difference depending on the turbo.
just about every independent dyno test will disagree with you. basic physics it's also no impact on spool times a good intercooler should offset any difference in air temperature which are regularly datalogged to show little reduction in temperature due to cold air intakes anyway, little temperature reduction = little power change
Thats the first thing I need someone to say in order for me to not take them seriously. Well done, I now have the firm belief that you're a kid who wishes they knew the first thing.
Jeesh, here come the agressive people that think they know everything. Well i said that because if i didnt it would just look like some one talking nonsense... --- Post updated --- Oh well if you really think that way i can't really do anything about it but if you just watch at least *some* stuff about cars you would realise you were wrong. (MCM/CarThrottle's MX5 build/and mainly the MTC Roadkill show all on youtube)
No way, that's complete nonsense. There's no way that a manufacturer would restrict the intake enough to kill thirty horsepower. In many cases, the stock air filter is the best air filter - pod filters and cold air intakes are just smaller than the factory airbox, that's why they're used instead of the factory one in custom/aftermarket turbo setups. Here's a great example, practically nothing they did, even a cold air intake through the headlight tubed way outside the car couldn't make more power.
Except you're both talking about the episode linked here, while on the S2000 build it actually did make a significant difference.. Not as huge as 20-30hp but they did make more with an aftermarket intake. But also that wasn't turbo so it's not really relevant bringing it up in this thread, but yea, a different air filter CAN (but does not have to) make a difference.
Actually they made about 3kw which even though it isn't noticeable it still seems like enough for it to possibly be a consistent gain in horsepower and a noticeable gain in street cred with the filter outside of the car, If the factory airbox was somehow mounted outside the engine bay it might have even more(but still not a noticeable amount) power. --- Post updated --- they are talking more about where its mounted as opposed to what kind.
Either way, i would love to have some kind of Air Flow Simulation depending on wether the intercooler is exposed improving engine cooling efficiency or the turbo is outside the engine bay (image1). It would be very nice to have something like this on the game.
I support the idea of better cooling for intercoolers, rads, or oil coolers when in the airstream, but still; those turbos aren't going to make more power just because they're outside the engine bay. Also, aerodynamics would be a really cool feature so that open hoods and other obstructions would slow down the car, and perhaps body kits could improve downforce.
I insert a stage 3 turbo (tuned appropriately) and remove the headlight to give the feel of a bit more power. Until the developers can implement airflow simulation I'll stick to this.
I think people above are confusing el-cheapo "looks cool" "cold air" intakes (the good 'ol, "aluminum pipe with a pod filter right over the stock exhaust manifold", upgrade) with actually providing an engine with colder air. The headlight funnels you see from time to time are used for a reason, and allowing an engine to get colder air is a very legitimate upgrade. It isn't a standalone upgrade, but it serves a purpose. Anything to fend off spark knock on an aggressive tune helps.
