Very informative video, thank you.
And thank you for indicating that it's atmospheric pressure that produces the flow into a normally aspirated engine and that it's not all that different than that of forced induction --- both methods work on pressurized air being pushed into the engine. It's just that one has greater air pressure than the other. Air is never sucked into an engine.
Hello from Toronto! Thanks very much for your clear explanation for someone who has NO background in auto mechanics!! We bought a 2021 Kia Telluride SX Limited for everyday use, and we noticed the term "naturally aspirated V6"; hence the search for an explanation! Awesome background you have there, and thanks again!
Glad my video helped you out! And thank you for the feedback, I really appreciate it.
Thanks for the very clear education!
You're welcome!
Sick srt4!
Thank you!
Hi from Jujuy Argentina. After watching plenty of videos yours is by far the best one, you have cleared most of my doubts. I own a Renault Sandero RS Racing Spirit which has a F4R naturally aspirated engine, the altitud of the city I live in ,Jujuy, is 4200 ft from Sea Level, the other day y went to another city about 13000 ft of altitud and my car literally lost all hp, had to slowly turn around and come back. What would you do if you were me? how would you compensate for the atmospheric pressure loss? (and please don't tell me sell the car as that's not an option for me at this point and with Argentina's economy fluctuating so bad) Thanks in advance!
Thank you for the feedback! As to your question situation, I would never suvgest selling the car. Unfortunately with that kind of altitude it's hard for naturally aspirated engines to continue to make power as there is less air available. The best option although not very cheap is to add either a supercharger or turbo to it. That way you can compensate for the lack of air at the higher altitude by increasing the boost.
Hey man great video! I have a e46 m3 what would you recommend?
Thank you! That's a great car you have there! My wife wants one in Laguna Seca Blue. If memory serves me correctly Dinan offers (or at least used to) a supercharger system for that car. I trust their work and would probably recommend a supercharger for forced induction over a turbo as that's what they use
@@LifeatSpeed thank you!!
You're welcome
Very informative, just the video I was looking for in completing between a scat pack and a hellcat. BEAUTIFUL Viper btw
Thanks! Glad my video helped
Hi, I just got my 2021 Lexus IS350 F sport, do you think I should add a turbo into it? Or should I just stick with NA? Btw I live in NY
Personally I'd leave it NA. Adding a turbo wouldikely be extremely costly, hurt your reliability and not gain enough power to be worth it.
@@LifeatSpeed thanks for the response, I personally really love the instant response with my 3.5L V6 NA engine, but I am trying to add some HP to it without adding turbo or supercharger. Do you have any advice?
Small power increases can generally made with items like; intake, exhaust, possibly ignition upgrades like more powerful coils and a tune. Big power gains get expensive with head work, cam change, pistons, etc.
i got one question, a few weeks ago i went to get my car tuned on a dyno but they said that since my car is naturally aspirated, i wouldnt be able to get a significant amount of power from the tune. i also mentioned wanting to add a supercharger but they said that im really not going to be able to get much more power out of my engine specifically because its naturally aspirated and that the best thing i could do is sell my car and get one with more potiental. would this really be the best option?
What kind of car is it and what engine is in it? They are correct that with a naturally aspirated engine the performance gains of adding just a tune will be minimal. You'll need to add other components like upgraded heads, camshaft(s), etc to see any real gains in a naturally aspirated engine.
@@LifeatSpeed Its a 2006 BMW 650i with an E63 4.8L v8
Adding a supercharger would be the best bet for that car. How much it would cost and if there are any "off the shelf" kits available for that platform, I'm not certain.
@@LifeatSpeed only one ive been able to find from very minor research is about 10,000 USD, which definitely wouldnt be worth it.
That's about what I would expect the cost to be. Adding forced induction isn't cheap. Especially if you want it to last and be reliable.
