I maybe incorrect did you own or still own an engine building shop?
He's the guy that seems to forget, as many do here, that a factory sealed coyote can make over 1000 RWHP with zero porting, stock throttle body, with the exception on INJECTORS. But you don't hafta take my word for it, just ask the crew at Midnight Racing.

Without trying to piss you off more. I think you're missing the point. No one is arguing that the coyote motor is not highly capable. The point being made is given the same motor. The car with the better list of mods will make more power. Porting a 18+ Intake is not worth a ton of power on it’s own. But 5 horsepower here, 10 there ads up to a better over all set-up. Is porting an 18 worth it? That’s totally up to the individual making the purchase. You likely only have a couple grand into your set up. I think your set-up runs good for the investment.

Perfect. Close the thread.

As a sole mod I do not think it is worth doing unless you are eventually going FBO and this is one of the steps to getting there. If you are only going intake and catback and nothing else then no. If you are going with a centrifugal supercharger system then it is a good upgrade. Or maybe it is something cool to have and say that you have.

One of the only reasons I ended up with a ported one is because Auto Mafia Racing had a steal on a ported one for just about the same price as a new one back during a Christmas sale. The porting job is actually really good when I checked it all out. No complaints here. I'll be pairing this manifold with an On3 single turbo soon.

Just because it CAN doesn't mean it's doing it efficiently. Nickels and dimes still add up dollars. You can totally make 1000whp with nothing but boost and fuel BUT you can do it easier with less boost with other mods. That's all anybody is really saying. The route one wishes to go is different and up to the individual

This community is as toxic as congress

Understand I don’t please english
Fixed it. I've always noticed when one has a valid point, out come the spelling/grammar nazis.

You didn’t fix anything but whatever.

my only point in my first comment was that not everybody wants to run their turbo or blower or whatever at 20lbs to make XXXX power figure when it can also be done at 10 with other parts. Worth is subjective. There’s been zero reason for you to be a douchebag about the whole thing

Your really think 10 hp is for 500 bucks on a FI car ? If you do, spend away.
Well a lot of people buy intakes for $300 or more and they don't add much HP. A ported manifold will increase power because the blower won't have to push the air through as hard. So it will work easier. And if it is working easier then it will make more power.

I agree. A lot of times in the past people have added cams, ported heads, headers, and other items to supercharged engines and actually lost boost but gained power. It happens all the time. Even if it does not increase power it might still be beneficial by allowing the blower to work less and thus reduce stress on the parts. So it is not a necessary item to have based on how well the stock unported manifold works. But there is some benefit to having one.

3 more this week on Lunds racing site went 7.80's.. No porting, Stock cams, stock ECU. 99% the records are No porting, stock cams, stock ECU.

I'm not sure what you think that proves. Nobody said that stock manifolds do not perform well. So your point is moot. Now if someone is running in the 7s then that is a testament to a lot of different factors on the car and a ported manifold would likely be unnecessary. But for a street car with boost, if the owner wanted a good bump in power and acceleration, then a ported manifold would help. See, there is a huge difference between an all out 7 second race car and a street car pushing some boost. Also, why does every debate turn into someone talking about 7 second this and 8 second that? You do realize that any car running those speeds, the results are attributable to the entire car and all parts working together right? You know they aren't running 7s and the main reason is because the manifold is unported right?
